B. MASTER PL~~ GUIDELINES/PURPOSE OF DOCUMENT
1. The Land Use-Development Plan (referred to as the "Plan" or "LUDP"). is a part of the planning process required by the East Bay Regional Park District Master Plan. the maj or policy document of the District (adopted 1973. revised 1980). The purpose of the LUDP is to direct future park development by: outlining expected levels of use and development, delineating general park character. planning access points and circulation systems. and dividing the Park into zoning units for recreation and for the natural areas which will preserve the significant natural resources of the park.
Quotes of Master Plan policies are reprinted in boxes throughout the report for clarification.
2 ,....------'---"-'---, EBRPD MASTER PLAN Land Use-Development Plan
The District will. following adoption of the resource analysis, prepare a land use-development plan prior to any significant development or substantial public use of the site. The plan will identify natural environment areas. environmental protective zones or any other designation within the parkland classification system which will control planning and management of the parkland and any recreation or staging area within the proposed parkland site. A schematic development concept or resource preservation plan will be prepared in map form along with supporting narrative. Specific sites will be planned with full recognition of both environmental and recreational needs based upon the resource analysis. Full consideration will be given to site resources to preserve significant resource values as well as public recreation need and demand as identified in policies relating to those areas of concern.
Recreation need and demand policies shall be based upon: data collected as part of the need and demand survey program. Expressed public desire for development or provision for activities. Evaluation of the recreational needs of current and future residents and overall regional system needs which can be met at a specific parkland. (Page 28) ,------__J
The Land Use-Development Plan is based on the conclusions of the Resource Analysis, public sentiment, as expressed in correspondence or at the public hearings, and the adopted policies of the East Bay Regional Park District in conformance with Regional and local plans. It will be followed by "Capital Improvement Plans" or design plans for development or improvement of specific areas.
2. The Natural Resources Management Plan (referred to as the "NRMP") , proposes objectives and policies with which to manage the land, water, vegetation and wildlife resources of the parkland.
iI 3. The Environmental Impact Report (referred to as the "EIR ), discusses the environmental impacts which could result from the implementation of the LUDP and suggests mitigation for possible significant impacts. Other project alternatives are also discussed. The Environmental Impact Report Policy is found on page 4S of the District Master Plan.
C. LOCATION AND DESCRIPTION
Anthony Chabot Regional Park (ACRP) is a 4,674-acre parkland (see D. Boundary line alterations) located in the Oakland/San Leandro Hills, east of Oakland and San Leandro. and north of Castro Valley. While residential areas skirt the Park to the south and west. undeveloped watershed lands border the Park on the east. and Redwood Regional Park
3 ..... ::.::... • > :;J~f • r--...... =>· ", I • • .- ....I ~ ~~ .~I!o I . I ...... E~UD\. I I \ I ,I _.II connects to ACRP on the north. ACRP is primarily an open space park of grass-covered valleys and west-facing hillsides. with dense brush and woodlands in the canyons and moist (east-facing) slopes. Tracts of eucalyptus. planted in the early 1900' s. cover large parts of the southern end of the Park. Major features are Grass Valley. Chabot and Las Cumbres Ridges (with many side ridges and canyons). and Lake Chabot. a manmade 315-acre reservoir (potable water supply). owned by East Bay Municipal Utility District.
The southern tip of Lake Chabot is a developed recreation area with marina complex. including fishing. boat rental. sightseeing launch. fishing pier with wheelchair access. Associated with the marina are family and group picnic facilities (including area for the disabled). turf meadows. horseshoe pits and exercise course.
Other recreational facilities at ACRP are disbursed throughout the Park and include the Chabot Marksmanship Range. a 67-acre motorcycle hill area, 7 youth group camping areas available by reservation. a Family Campground (73 sites which accommodate campers. vans. tents. trailers and RVs). and Willow Park Public Golf Course with driving range.
One of the maj or recreational activities at ACRP is the use of the extensive trail system by hikers. joggers. equestrians and bicyclists. There are 37.5 miles of unpaved service roads. and 4.5 miles of paved roads serving the marina and the family and group camps. One trail through the length of the Park is designated as part of the East Bay Skyline National Recreation Trail. and connects the Park to Redwood Regional Park. EBMUD trails connect ACRP to Las Trampas. Several miles of narrower. non-vehicular hiking/equestrian trails are located in the park.
Lake Chabot is operated by staff headquartered at the Lake Chabot Service Yard at the former NIKE site above Lake Chabot. Also housed at this site is the EBRPD Public Safety Department and the South County Corporation Yard. This area (132 acres) is owned by the South County Community College District. The Park. other than Lake Chabot. is currently operated from the Redwood Service Yard.
The original inhabitants of the ACRP area were the American Indians (the Costanoans). although there are no known habitation sites in the Park. The Mexicans arrived in the Bay Area in 1775. and in 1843. the southern half of ACRP became part of Rancho San Lorenzo. Cattle grazing (for hides). became the major use of the land. It came into American hands in 1846. In 1875. the Contra Costa Water Company began acquiring watershed lands here to provide a reliable source of water for the Oakland area. The dam and lake were also constructed in 1875 by Anthony Chabot. Cattle grazing continued as the maj or land use other than watershed purposes.
In 1952. ACRP land was first purchased for park use by the newly formed East Bay Regional Park District. Lake Chabot and its surrounding acreage was added to the Park in 1966. (See Section II.A for a more detailed history).
A more complete description of natural and manmade resources. including recreational facilities. is found in the Resource Analysis.

6 Fig. 2 MAJOR ··FEAfURES NAMING D. OWNERSHIP AND ADMINISTRATION
Of the 4.674 acres comprising Anthony Chabot Regional Park, 3.409 acres are owned in fee by the East Bay Regional Park District. The 133 acres containing Public Safety and the South County Corporation Yard are leased from the South County Community College District for a 20-year term ending in 1996. The 1.178 acres comprising the "Cordone Sanitaire" area around Lake Chabot and Willow Park Golf Course are leased from the East Bay Municipal Utility District for a term ending in 1997 (the lease on the Willow Park Golf Course ends in 1989. with a 25-year extension running to 2014). In accordance with an agreement amendment, the area to the west of Bass Cove has been added to the 1.178 EBMUD lease. The Bass Cove trail through this area provides the opportunity for joggers and hikers to venture around the entire lake.
In addition. a trail between the dam spillway and Estudillo Avenue and Sylvan Circle at San Leandro's Chabot Park, is open under license from EBMUD to EBRPD who operates and maintains it. The 10.S-acre "Chabot Park" is operated by the City of San Leandro and contains basketball, horseshoes, nature walk, bike paths, picnicking, play apparatus and play fields. and volleyball. When the parking lot is closed, trail users must park on the street to get onto the trail into EBRPD's Anthony Chabot Regional Park.
Boundary Line Alterations
The official boundary line between ACRP and Redwood Regional Park has been located at the Natural Dam extending to Pinehurst Road. This designates an approximate 422.S8-acre area of parkland south of Redwood Road as a part of Redwood Park. While this area is within the same watershed as Redwood Park, the MacDonald Staging Area has long been identified by park users as a part of ACRP. It seems likely that in the public's perception. Redwood Road is a more identifiable feature than a ridge for a park boundary line.
Adoption of this plan redesignates the boundary line between the two parks as Redwood Road, and will serve also as an amendment to the Redwood Regional Park Land Use-Development Plan. Thus, ACRP will contain S096. 58 acres and Redwood will contain 1806.62 acres on all official records.
Operationally, this area is a grey zone, as it falls at the edge of two operational boundaries. The local operating staffs of the Parks and Interpretation Dept. shall determine which park crew will be responsible for this area. The operating unit may change from time to time as conditions change. Any accounting system involved in operations shall consider the area to be under the jurisdiction of the operational unit responsible.
8 E. PARK NAMES
Currently used facility names are found in the park brochures (published by the EBRPD Public Information Department) and currently used feature names are found in the Anthony Chabot Regional Park Resource Analysis.
The following new facility names are used in the LUDP for areas that did not previously have names.

Many recreational groups publish maps which will become outdated with these changes, and some confusion by park users may occur. These inconveniences are unfortunate. The District will make a concerted effort through signing and correspondence, to eliminate confusion. A lO-acre park, run by the City of San Leandro. is located below the dam at the end of Estudillo Avenue. This park is named "Chabot Park", which causes some confusion with Anthony Chabot Regional Park. The lO-acre park will be referred to as "Chabot City Park" in this report, for ease of discussion. 12 II. BACKGROUND A. PARKLAND PLANNING Al\1D ACQUISITION HISTORY Acquisition History Public acquisition of the lands in what is now Anthony Chabot Regional Park began in 1875 by the Contra Costa Water Company (CCWC) in order to serve the growing water needs of Oakland. Lands were secured for both watershed area and reservoir sites. Also in 1875, Lake Chabot was constructed by a Canadian engineer, Anthony Chabot, utilizing hydraulic lnining techniques which he had invented, Chinese laborers for spreading, and 200 wild horses for compacting the dam. The reservoir served as the mainstay of the East Bay's water supply for 40 years. By 1890, the Water Company had acquired the former lands of Rancho San Lorenzo, which is the southern end of today's ACRP) , and part of the San Leandro Creek watershed. In 1906, the CCWC and several other water companies were united into the People's Water Company which immediately began further land purchase in the Grass Valley Creek and San Leandro Creek watersheds (the northeast end of what is now the park). People's Water Company also began large-scale eucalyptus plantings in about 1910, adding to the existing wind block plantings, which have since greatly changed the landscape of the area. By 1915. all but 25 acres of the Grass Valley area was watershed land. In 1916. the People's Water Company was reorganized as the East Bay Water Company (EBWC). The East Bay Municipal Utility District (EBMUD) was created in 1923, which acquired the entire holdings of the EBWC in 1928, including 40.000 acres of land in the East Bay Hills (of these, approximately 15,000 acres were declared surplus). A railroad right of way across the Grass Valley Ranch, once considered as a route across the hills, was acquired in 1937. In 1952, 3,100 acres of land were sold to the EBRPD. which were called Grass Valley Regional Recreation Area. Planning History Parkland planning of the ACRP area began long before the EBRPD was formed. As the nine cities which bordered the east shore of San Francisco Bay grew in the early part of the century, many residents recognized the need for an adequate park system and for preservation of the hill lands. A unique opportunity presented itself when EBMUD declared some of its lands surplus in 1928. In that same year, several park associations were formed to determine which portions of the surplus lands were suitable as parkland, and to appraise the public of the recreational opportunities. Resolutions were presented to EBMUD to delay sale until public sentiment could be ascertained. Studies were begun in 1929 by the Olmstead Brothers, Landscape Architects, and Ansel F. Hall of the National Park Service, in cooperation with the University of California, Bureau of Public Administration. In 1930, the "Proposed Park Reservations for East Bay 13 RESERVE • p~ ..

With their many miles of existing hiking and bridle trails (p. 23), the report recommended that the greater parts of lands be retained in their "natural" condition. with smaller parts developed for field sports, picnic grounds, camping, etc. (p. 28) and that a general plan of land use be evolved. Concern was expressed that the parks "services" (concessions, etc.) be for the enj oyment of the people, rather than for making profits from park users. Most of what is now ACRP, excluding the area of the lake, was declared as surplus land and the report recommended it for parkland. With proposed facilities, it was, in effect, the first Land Use-Development Plan for ACRP. A golf course was proposed in central Grass Valley, picnic groves in the hills north of the lake, and a playfield near where the marina is now located. Several new trails were recommended, as well as new roads, including roads crossing the Park in several locations. Service centers were proposed in central Grass Valley, lower Grass Valley. in the hills north of the lake in the picnic grove, and where the Lake Chabot Marina complex is now located. Also, as a result of the public attention generated over EBMUD's surplus lands, a new agency, the East Bay Regional Park District, was created in 1934, to acquire and preserve the appropriate surplus lands as parks. In 1936-39, some 4,000 acres were acquired. Acquisition of Grass Valley, however, did not take place until 1952. when 3,100 acres were purchased. Grass Valley Regional Recreation Area was created in 1952. Developing the Park into a useable area was described as the District's biggest project in the 1955 Annual Report. In 1955, the Park District's first Master Plan was accepted by the Board of Directors. The Plan included: the layout of a golf course in central Grass Valley, with entrance roads from Redwood Road and Skyline Blvd.; a chalet-hostel at Natural Dam served by road from Skyline Blvd., various picnic areas along Redwood Road, Skyline Blvd. and Hawk Ridge areas; parking at Marciel Gate; extensive picnic and group camp facilities on the broad upland of Chabot Ridge, with a field house and play meadow adjacent to a 600-acre natural area which extends near the lake. Two motorcycle runs were located along Redwood Road. Lake Chabot went on "standby" status in 1962, which made public use of the reservoir possible. Thus, Lake Chabot came under the operational jurisdiction of the Park District. In 1966, a new Master Plan was prepared and adopted by the District Board of Directors. It recognized existing uses and proposed major recreational development in the Park, including: regional conference center, camping on Chabot Ridge, golf course (Redwood Road). boating center-lake, hilltop lake/swim complex (Lost Ridge), archery range (Redwood Road), visitor's center, equestrian center, picnic area (Grass Valley), botanic reserve (northern Grass Valley), service yard (Redwood Road). 16 .. -" .-.- .... _._._._._._ ... _..

This Master Plan presented comprehensive policies for parkland planning, development and preservation. ACRP was formally classified as a "Regional Park". In accordance with the Master Plan planning sequence, a Resource Analysis was prepared and was accepted in June 1978. This report is the next step in the planning process. B. REGIONAL AND LOCAL AGENCY PLANS The General Plans of Alameda County Cities of Oakland. San Leandro and East Bay Municipal Utility District are discussed in Chapter V, EIR, C.l. Land Use and Planning. C. ADJACENT LAND USE This is described in Chapter V. EIR, C.l. Setting. Chabot is described ll as one of the District t s "front line parks that is one of the major parklands in the Berkeley-Oakland Hills that borders the vast East Bay population. Bordering Redwood (to the north) and EBMUD lands (to the east) make it a part of a vast East Bay open space area thousands of acres in size which separates urban areas, provides wild animal and plant habitat and regional recreational and open space opportunities. D. 30-MINUTE PLANNING ZONE 1. Master Plan Policy has suggested a planning zone which serves a population within 30 minutes driving time of a park. Within this zone, special attention is given to park access. public transportation, and the supply of regional recreation facilities. This knowledge is important in establishing recreational needs and access needs in the park. (Refer to Fig. 1 for the zone area). EBRPD MASTER PLAN Area of Influence Policy The District will plan and develop a parkland system designed specifically to meet the needs and demands of District residents. A planning zone. based generally on a 30-minute travel time or on a park use profile adapted from the 1976 I Tyler Study, shall identify principal users and potential users " of a parkland whose opinions, along with other interested District residents. will be actively sought prior to design of I ~~ parkland. (Page 27) .. ~_._~ "_l 2. Auto and Trail Access Anthony Chabot Regional Park is well served by public roads, with approximately 2/3 of the park bounded by Redwood Road, Lake Chabot Road and Skyline Blvd. Major auto access is at Marciel Gate and 18 \ ..

These and other staging areas on the edge of the park are shown in Fig. 7. ACRP is connected to Redwood and other parks to the north by the East Bay Skyline National Recreation Trail. This trail connects to EBMUD's Upper San Leandro Reservoir area and will eventually lead to Garin Regional Park (see Fig. 18). There are a few access points into the park to serve local residents. 3. Public Transportation Anthony Chabot Regional Park is not regularly served by AC Tansit. The 91 line, however. sometimes serves Lake Chabot in the summer, if a special busing program is enacted by the AC Transit board. There is no other convenient access to other recreation areas of the park. Those who would consider a long hike could reach Redwood Park on the 15A or enter ACRP at the Equestrian Center or Parkridge Drive from the 46A last stop at Skyline Blvd. and Hansom. 4. Population The population of the 30-Minute Planning Zone is estimated at approximately 730,000 and represents 66% of Alameda County, and 7% of Contra Costa County (estimates taken from 1980 census). TABLE 1 PLANNING ZONE POPULATION Population Estimate Oakland 339,000 San Leandro 64,000 Castro Valley 44,000 Hayward 94,000 Union City 39,500 Alameda 32,000 Moraga 15,000 Danville 26,000 Lafayette 10,000 Orinda 17, 000 Dublin 13,000 San Ramon 22,000 Pleasanton 15,000 The District's "Balanced Parklands Plan" (see Fig 5) divides the District into several subregions in order to better assess parkland distribution and speCial recreation needs. Anthony Chabot Regional Park is at the southern edge of the West Metropolitan area and predominantly serves it as well at the South Metropolitan area. 20 5. Regional Recreation Supply Anthony Chabot offers a variety of regional recreational opportunities including picnicking, hiking, riding (incl. horse rental), camping, fishing, golf, marksmanship, motorcycle trail opportunities. For some of these activities, there are other similar recreational opportunities in the 30-minute zone which are listed below. These are provided by other EBRPD parks, other agencies and, in some cases, private individuals. EBRPD Within the 30-minute zone there are several other regional parklands which provide some of the same activities as ACRP. These are listed below. Las Trampas - hiking/equestrian trails, family picnic Sibley - hiking/equestrian trails, jogging/running trails, family picnicking Huckleberry - hiking trails Temescal - fishing, family and group reservable picnicking (turf), bicycling, hiking, jogging/running trails Cull Canyon - fishing, family picnicking, hiking/equestrian trails. Garin - fishing, family and group reservation picnicking. hiking/equestrian/jogging/running trails. turfed play areas Alameda Creek Quarries - fishing, family picnicking, hiking Little Hills - hiking/equestrian trails, group reservation picnicking Redwood - family and reservable group picnicking, hiking/equestrian trails. jogging and running trails, Hunt Field (a show jumping field), youth group camping, archery range Don Castro - fishing, hiking/equestrian trails, family and group reservable picnicking Dry Creek Pioneer - hiking/equestrian/jogging and running trails Other regional recreational opportunities are provided within the 30-Minute Planning Zone by East Bay Municipal Utility District. Lafayette Reservoir has a lake with marina and boat rentals (non-gasoline), fishing, bike and jogging/hiking trails, and picnicking (family and group, 115 ac.) In the Upper San Leandro Reservoir area. the lake and shores are off-limits to visitors. M8.ny other permit-only trails for hikers and equestrians are available. This open space area is adjacent to ACRP on its northeastern side and a few trails between the two parks connect. Future plans for Upper San Leandro area include a recreation area and boating opportunities. Siesta Valley. which partially falls within the planning zone, is open by permit to school and research groups for nature education. Public golfing is provided within the 30-minute range at: Alameda Municipal Golf Course, Galbraith Golf Course (Oakland), Hayward Golf Course, Marina Golf Course (San Leandro), Lake Chabot Municipal Golf Course (Oakland), Diamond Park (9-hole golf course 21 and pee wee course). No other camping areas are located within the 30-Minute Planning Zone. Anthony Chabot provides the major publicly owned facilities providing boarding, horse rings, and horse rental in the planning zone. Hunt Field in Redwood Regional Park is an olympic style equestrian facililty including jumps and an arena. Another arena is available at Joaquin Miller Park. There are many privately owned boarding facilities and a few horse rental facilities throughout the zone. The only other gun range open to the public in the planning zone is the San Leandro Rifle Range. The nearest SOO-meter range or metallic silhouette is located in Reno, Nevada. Some city parks provide family and group picnicking facilities and small trails, etc. These are not considered regional facilities, however, and are not listed. One exception is the 513-acre Joaquin Hiller Park adj acent to EBRPD' s Redwood Regional Park. owned and operated by the City of Oakland. It has hiking/equestrian trails, arena, group camps and family and group picnic areas. Boating and fishing are available at Lake Merritt, and Estuary Park (Oakland) provides boating and fishing. Marina Park in San Leandro provides boating and fishing. There are no motorcycle areas within the 30-Minute Planning Zone. Motorcycle facilities generally draw visitors from a greater service area. Within an 80-mile radius of Chabot are the following motorcycle areas: Carnegie (Alameda Co.), Sand Hill Ranch (Contra Costa Co.), Sears Point (Sonoma Co.), Knoxville Recreation Area (Lake Co.), Prairie City OHV Park (Sacramento Co.), Frankie Raines-Deer Creek OHV Park (Stanslaus Co.), Santa Clara Motorcycle Park (Santa Clara Co.), Police Athletic League (Santa Clara Co.), and Hollister Hills (San Benito Co.). None of these sites are located adjacent to a large metropolitan population. Within this 80-mile radius, only one potential site in Solano Co. is being considered for future use by the California Department of Parks & Recreation. E. PUBLIC USE AND DEMAND 1. Existing Park Activities at Anthony Chabot Regional Park Anthony Chabot Regional Park is well used by those who hike. ride, bike. camp, shoot, fish, picnic and golf. The existing facilities are described below and also in Chapter III.C. Development Program. Picnic and Meadow Use Both family and group picnicking sites are relegated to one area of the park - the Lake Chabot Marina. There, a recently improved and expanded facility services approximately 100 families and 5 groups (for groups between 50 and 125 members, one of which serves wheelchair groups). The picnic areas are located near or adjacent to irrigated grass meadows, and one area has a good view of the lake. The facility is well used and popular. 22 Camping Camping is one of the major uses of the park for both families and groups. Five day and overnight group camps are located on ridges above Lake Chabot. These camps provide all-weather access road. water, chemical toilets, picnic tables with BBQ's and trash cans. They are well used on a reservation basis. Camping for larger groups (500 max.) such as scout jamborees is available at Bort Meadow. A 73 campsite (12 sites for trailer/RVs with sewer hookups) family campground overlooks Lake Chabot within a eucalyptus forest. Trail Use One of the major uses of the park is the trail use (predominantly by hikers and equestrians) of the extensive trail system (approx. 40 miles). These trails are well established. They consist of dirt hiking/riding/service trails; narrower hiking and riding trails and hiking only trails in steep terrain. One length of trail through the park is designated as a Regional trail. The Regional trail system connects the various parks of the EBRPD. Paved trails serve bicycles and service vehicles. Joggers use trails convenient to staging areas. Equestrian Facilities The Anthony Chabot Equestrian Center on Skyline Blvd. provides boarding and rental horses. It is convenient to the park trail system. Marksmanship Range This public range includes rifle. pistol and shotgun ranges and snackstand. and is run by the Chabot Gun Club. Motorcycle Trails A 66-acre motorcycle area was established in 1954. It is located on Redwood Road between ACRP and East Bay Muncipal Utility District. The closest residents to this area are approximately 1!2-mile to the west (as the crow flies). It is basically an undeveloped area with many dirt trails traversing the hills of the area. Many trails have eroded down to base rock. Informal parking is available on several undeveloped flat areas adj acent to the road. No services are provided. The 1966 Master Plan specifies that it is to be relocated in the future. It is the only free (non-fee) motorcycle area within the two-county area. Archery A IS-acre site. in an eucalyptus grove. was constructed by the So-Ea-Ba Archery Club years ago. and contains target and field 23 ranges. The club has since disbanded, and the 1972 eucalyptus freeze and lack of maintenance has left the site in a state of disrepair. It is still occasionally used by individual archers. Golf The 11O-acre Willow Park Public Golf Course provides an i8-hole course, putting green. driving range, pro shop. restaurant (with lounge, banquet and dining room) snackbar and outdoor wedding site. Fishing and Boating The Lake Chabot Marina serves as the gateway to Lake Chabot. a 315-acre lake stocked by Fish & Game. Facilities include a coffee shop that sells fishing permits, boat rental, including rowboats (electric motors), pedal boats. canoes and sightseeing launch. The 3-mile east shore and vlest shore and trails along the lake edge provide good access for shore and dock fishing. No swimming or private boat launching is permitted. Ropes Course Since 1979. the Alameda County 4-H organization has operated an adventure ropes course at Lower Lost Ridge (See Fig. 16). The course is a series of approximately is simulated wilderness challenges of obstacles built in the trees out of wire cable. wood platforms. log and rope, for individuals to challenge their physical skills. The "wilderness" quality of the site has been appropriate for this facility. The maj or season of operation is from April to October, although year-round use is feasible. weather permitting. Facilities for the Disabled Lake Chabot has a reservable picnic area which serves 35 picnickers. It is located near the lake, concession and restrooms. It is also near a fishing dock, designed to accommodate the disabled. Wheelchair access is available at the target and firing lines of the Marksmanship Range, and construction is underway to make other areas accessible. The Chabot Gun Club has recently started a disabled shooting program. 2. User Surveys The 1976 Tyler Need and Demand Survey of Park District residents conducted seven days of interviews at ACRP, talking to 106 park visitors. The most relevant questions, and their responses concerning existing and future facilities is shown below. 24 What (do you think you'll) (did you) enjoy most about being in the park today? 63% - activities made available 41% - natural environment 19% - getting away from it all 7% - sun. sunshine/nice weather 4% - social atmosphere 3% - clean park. beach What (do you think you'll) (did you) enjoy most about being in the park today - Activities made available? 29% - fishing 17% - walking. hiking 14% - shooting range 6% - boating 5% - picnicking 2% - playing games. sports 1% - bicycling 1% - walking or running dog 1% - jogging 1% - play area for children 1% - camping As far as you are concerned. what changes. if any. in this park might be made to make your coming here a more enjoyable experience? 45% - more recreational facilities 21% - improve the cleanliness 18% - nothing. everything is free 10% - improve grounds 6% - more restrictions/enforce restrictions 5% - more public convenience facilities 4% - improve restrooms More Recreational Facilities 45% 12% - stock more fish 10% allow more swimming 6% have international shooting 6% - more boating facilities 6% - more hiking trails 6% more picnic areas 4% more. larger recreation areas 4% more equipment for children 3% - more bike paths 1% - more campsites 1% more tennis courts 1% expand the beaches. waterfront 1% more motorcycle trails 25 Which activites listed have you ever done in this park? 64% - picnicking 64% - hiking 58% - fishing 52% - sightseeing 48% - boating 39% - loafing (sunbathing on the lawn) 35% - frisbee tossing 32% - walking or running dog 29% visiting the marina 28% - bicycling 26% - jogging 20% - softball/football 12% - sunbathing by the water 12% - camping/day 5% - other 5% - camping overnight 4% - golfing 3% - archery 2% - horseback riding 2% - photography 2% - motorcycling 2% - kite flying 1% - studying, reading Which of these activities did you or anyone in your party actually do in the park today? 43% - hiking 30% - fishing 23% - sightseeing 13% - loafing/sunbathing on lawn 13% - picnicking 13% - walking or running dog 13% - boating 13% - visiting marina 10% - other 7% - frisbee tossing 7% - bicycling 3% - sunbathing by water 3% - jogging 3% - softball/football 3% - camping overnight 26 3. Public Ideas on Park Resources and Future Development .._-_.__ ..__.-._._.__ .. __._-_ __._.~ .. _"__ 1 EBRPD MASTER PLAN Public Hearings To provide the public an opportunity to express its op1n10n about the resource analysis and to comment on potential I development and uses of a new parkland site. public hearings will be held in the planning zone for each parkland in the following manner: 1. Following completion of the resource analysis. to review the analysis and to solicit public comments and suggestions which should be considered in the formulation of the Land Use-Development Plan. 2. Following completion of the Land Use-Development Plan and prior to Board approval of the plan. to provide an opportunity for additional public review and comment. 3. Such public comment shall be for use in final plan. (page 29) L_ ---- _...._.._--_...... __ ._~_ .._--_._-----_..- Public meetings are the major forum for District residents to express their desires concerning the future use of a parkland. A public workshop was held in Castro Valley on August 31. 1982, at the Castro Valley Communi.ty Center. Aproximately 130 members of the public were present. The resources and existing facilities of the Park were described to the audience and then the meeting was open for public comments. Many park use ideas were proposed. Individuals and spokesmen for organizations. included homeow~ers. motorcycle enthusiasts. runners. hikers, bicyclists, equestrians. marksmen, group campers. archers and picnickers. These ideas are categorized and are listed below. and the list also includes comments received in letters and telephone conversations. Natural Resources Management Vegetation: Coyote brush should be controlled. Grass Valley should be returned to grassland (from coyote brush) lack of eucalyptus maintenance in archery area is a fire hazard reduce poison oak around the Family Camp graze cattle to reduce fire hazard and brush encroachment reduction of the fire hazard should be undertaken due to the proximity of critical watershed land east of the park. Grazing can reduce fuel and encourage open grassland efforts of reforestation should include increased maintenance, including brush removal the fuel loading in eucalyptus groves from the archery range to Stone Bridge should be reduced with brush management and fire breaks 27 Wildlife: deal with habitat maintenance to help protect wildlife mosquito abatement is needed in the Big Trees area look into natural mosquito abatement Coyote brush and poison ivy are taking over trails in motorcycle area and need control have a youth trapping contest to capture feral cats bring hunters into the parks to round up unwanted wild animals such as feral cats and take them to the SPCA rather than use poisons, traps or bobcats have the SPCA or District trap feral cats and fine those who abandon animals and sign this in the parks there should be management policies for protection of deer from dogs dog droppings are a health hazard in the park poisoning of cats will be a threat to other animals and humans humane boxtraps should be utilized to capture unwanted animals rather than other methods previously proposed initiate a publicity campaign to alert homeowners that dogs will be trapped if a problem by Alameda County Animal Control ducks and geese should be caught and taken to a wildlife preserve Water: fishery enhancements such as habitat or spawning/shelter habitat, and addition of a forage fish should be considered Grass Valley Creek flow would be improved above Bart Meadow with brush removal debris in a large gully at the firing range should be replaced with a standard erosion control method Soil: deal with erosion problems incorporate mitigation measures (such as culverts, drainage ditches, drop structures, gully plugs, sediment basins, energy dissipators) for severely eroded areas of the park {particularly the motorcycle area). Park Character keep Chabot a natural park especially keep area at Natural Dam and MacDonald gate natural keep Bart Meadow in native grasses so it continues to fit in with the natural park character Level of Development keep development away from property owners near Grovenor Gate do not implement any of the facilities on the 1966 Master Plan that have not yet been built (such as the Convention Center, thru park roads, hilltop lake, etc.) don't construct anymore day-use facilities (like picnicking). Use money to upgrade existing facilities 28 Access do not provide off-street or on-street parking at Chabot City Park below dam at Estudillo Avenue; adjacent neighbors already have had a lot of problems (vandalism, drugs. etc.) because of City Park parking lot investigate the possibility of an alternate staging area on Lake Chabot Road across from the quarry do not reopen Grovenor Gate provide adequate parking at Proctor Gate do not allow a parking lot down in Bort Meadow, keep it up by the road Recreational Facilities Archery: maintain the archery range so it can be used by interested people and groups. Provide water, tables and a picnic area close the archery range down since there is no responsible club maintaining and operating the site keep range open even if it is not a "Regional" facility allow the Bonnie Bowmen to rehabilitate the archery area in stages and operate it as a concession Marksmanship Range: Chabot Gun Club should be expanded because it lacks some types of range facilities and is at its maximum capacity. Some other local gun clubs in area are closing. making this range and proposed facilities more important Motorcycle (also see Natural Resources Management comments): keep this motorcycle facility: is good for all types of motorcycle riders; is closest legal place for off-road use. Closing down motorcycle area would result in motorcycles going into non designated areas upgrade and maintain this facility provide parking, toilets, water remove blind corners in course State funds (green sticker registration fees) for motorcycle area development should be applied for facility is ok as is do not upgrade the area with better parking, toilets and water don t t make any improvement that would necessitate charging an admission fee fix erosion problems (install water bars. fill ruts of major trails with gravel, plant pine trees in areas which you want to keep cycles off). Use State funds and volunteer labor expand area with a motocross track do not allow 4-wheel vehicles divide the site into beginners, advanced areas do not divide the area into different sections, it will be too hard to enforce 29 Golf Course: if the golf course leaves, convert it to an archery range if the golf course leaves, convert it to a nice campground if more golf course space is needed it should expand into adjacent marsh Picnic: provide more family picnicking (outside of the Marina area) make greater use of Bart Meadow with some day use provide more group picnic facilities including those for large groups (500-1,000 people) Marina: consider allowing private boats, cartop sailboats (with cockpit), rubber rafts (EBMUD) Camping: (General) camps should have privacy and a large staging area for cars, but not be near a large through-road (Group Camps) Bart Meadow the EBRPD has made commitments with the California State Horsemen's Association and these should be kept in any new plans provide a good group camping facility maintain horse access through the meadow: keep the 75 pipe horse-tie stalls where they are, provide four water stand pipes at locations agreed upon, maintain the overnight equestrian camp provide picnic opportunities especially for large groups leave Bart Meadow as it is - a camp that can serve hikers and equestrians, don't use it for picnicking don't put in irrigated grass that would look strange don't put in a parking lot in the meadow, keep it free of cars make greater reservab1e day use of the area provide irrigated lawns to play on Puma Point - (located at the south end of Family Camp) provide a good area for an equestrian camp (75 horses), including horse ties, picnic tables that can also be used as a trailside picnic area provide another equestrian campsite near Skyline Blvd. at Grass Valley Gate (formerly Chabot Gate) provide a primitive campsite for Boy Scout type groups where the kids can dig their pit toilets, make benches out of fallen logs, etc. Roads, toilets and water are not needed 30 (Backpacking Camps) provide a backpacking camp in the north end of the park (north of Bart Meadow) Trails: Chabot should be a trail park and have trails that traverse varying terrain narrower trails are the most enjoyable and most of trails are service roads;. more narrow trails are needed provide hiking only trails (no vehicles and horses) for the more sophisticated hikers toilets and drinking fountains should be provided at trailheads like Proctor Gate and along the trails for hikers and horsemen (trail users trespass on private property for water where none provided by parks) picnic tables and benches should also be provided along trails at rest areas for weary trail users provide water for horses along trail, e.g. develop spring south of McDonald Gate provide mileage markers on trails construct a braille trail (one is proposed in Redwood-Canyon Meadow) cosider allowing night hikers in park especially for day workers allow dogs to run naturally without leash don't bring trails into neighborhoods, this brings problems to the residents keep trail development away from back fences. especially at Grovenor Drive and Chabot City Park put in a switchback trail from lake to Anthony Chabot Family Campground (formerly Las Cumbres) as current one is too steep construct hiking/riding trail loop from Bort Meadow to Natural Dam Parkridge Gate (volunteer labor available) provide better trail access into the park on Oakland side. so people don't have to trespass through golf course Skyline Trail now dead-ends. it should connect to other trails connect Central Trail to Brandon at Valley Trail intersection location provide a shoreline loop around the lake for hikers and runners; pave shoreline loop for bikers; keep shoreline loop dirt (the whole world is already paved) vary elevations on trail for interest keep shoreline loop at lake level there are existing trails around the lake (on EBMUD land), so just open one up to public do not open a loop trail around the lake. This will bring more people into adjacent neighborhoods. some of whom will create problems for homeowners put in another bike trail from Chabot City Park to Lake Cha.bot Marina that isn't so steep as West Shore Trail; existing EBMUD trail below dam would be good. This will be a safe bicycle alternative for Lake Chabot Road 31 do not extend the Eastshore Trail (formerly Lakeview Trail) into the neighborhood below the dam because of past problems provide a trail to future Leona Heights Regional Park Equestrian Facilities (also see Group Camps & Trails): keep all existing equestrian facilities move Hunt Field from Redwood to Chabot because Hunt Field is not safe with rock exposed. and is not large enough for the larger 3-day events leave Hunt Field where it is because it is near the 2~ mile cross-country course on West Ridge of Redwood Regional Park make Chabot Equestrian Center more profitable, with a dressage area and riding school provide more horse boarding Miscellaneous the closed Grovenor Gate is an eyesore and should be fixed up to look better allow a quarter midget race course to be constructed at Marciel Gate allow a survival course to be constructed at Marciel Gate consider alternatives in regards to the operation of the small park leased to the City of San Leandro Comments received in subsequent hearing after publication of the Draft LUDP/EIR are found in the appendix. 32 III. LAND USE-DEVELOPMENT PLAN A. PARKLAND CLASSIFICATION AND REGIONAL PARK ACTIVITIES EBRPD MASTER PLAN Parkland Classification Policy and Designation The District Board of Directors will classify all parkland units which are, or shall become. a part of the East Bay Regional Park District system, into one of the following classifications: Regional Park, Regional Shoreline. Regional Preserve, Regional Wilderness, Regional Recreation Area (includes Off Road Vehicle Recreation Areas), and Regional Trail. The Land Bank category will be used for all other District lands which have not been assigned by a Board action to one of the above parkland classifications. (Page 10) This Plan establishes the classification of "Regional Park" for Anthony Chabot as suggested by the EBRPD Master Plan. (See Fig. 5, Balanced Parkland Plan) The Master Plan's Recreation Policies (p. 30) list the following activites as being appropriate for Regional parklands: Regional Gutdoor Activities 1. Facilities required If consistent with the parkland classification, the following activites may be considered for site planning and facilities provided for them: backpack camping, bicycling, boating, *botanic garden, children's environmental play areas, family camping, family picnicking, fishing, group picnicking, hiking, horseback riding, *merry-go-round riding, *miniature trains, meeting rooms, nature centers, oudoor sports and non-structured pursuits on turfed meadow areas, pony rides, sunbathing, sWimming and related aquatic activities, youth group camping and physical exercise. *(Includes activities which exist at Tilden but are not included elsewhere.) 2. Facilities not required Activities not requ1rlng facilities that may be planned for: bird watching, blanket picnicking. experiencing wilderness and open space appreciation, games such as horseshoes, volleyball and lawn croquet where the participants bring their own equipment. nature hikes. open space activities such as contemplation. painting, photography. sight-seeing. study and educational pursuits. 33 Special Interest Recreation Such activities currently authorized for consideration in planning are: field archery. bee keeping. bocce ball. disc golf. equestrian arenas, jump fields. stables and rental strings. hang gliding. marksmanship range. model airplanes, model boats. motorcycle and ORVis, pet exercise and training. B. REGIONAL PARK PURPOSE EBRPD MASTER PLAN Regional Park Purpose The purpose of a Regional Park is to provide a spacious area , with outstanding natural features where a variety of outdoor I recreation opportunities can be provided for the enjoyment and education of the public. (Page 10) ~.._,.,.,~u~,.... ~,.~·..~,,,-,-,.w--,~~··.~, •.•• ··,_._._,-_·_.""-"-"~""""~""""~'~'~""'~'~"""'"~"" ~""'" .. C. DEVELOPMENT PROG~I EBRPD MASTER PLAN Minimum Standards For an area to be considered suitable for designation as a Regional Park, it must possess the following characteristics: 1. A Regional Park is an area of land, or land and water, of approximately 500 or more suitable acres. 2. Seventy to ninety percent of the area must have, or potentially have. a scenic or natural character. This portion should be designated as a Natural Area for planning and management purposes. 3. Ten to thirty percent of the area must be suitable for accommodating a variety of recreational activities. This portion should be designated as a Recreation Unit for planning and management purposes. (page 10) Anthony Chabot Regional Park meets the overall acreage standard for a Regional Park. ApprOXimately 955 acres or 19% of the park is designated as Recreation Unit by this Plan and correspondingly 81% as Natural Unit. 1. Development Concept The level of development proposed in the 1966 Anthony Chabot Regional Park Land Use-Development Plan (then titled the "Master Plan", Fig. 4) has never been fully attained. Among the facilities 34 never constructed are the Visitors Center. swimming complex. Regional Conference Center. various day use and picnic areas. bicycle concession. sports fields and botanic preserves. The 1966 Plan was drawn in a more development-oriented era and today the values of natural resource preservation. open space. and associated types of recreation have assumed greater importance. particularly near the urban areas where relief from asphalt. cars and buildings is most welcome. With this expanded recreational outlook. the general development level of ACRP seems appropriate and the need for many of the facilities mentioned above no longer seems urgent or necessary. Thus. the general existing character of the park will be retained in the new Plan with the retention of most existing facilities. Most of the unbuilt facilities proposed in 1966 will be deleted from the Plan. The major expansion that will take place will include additional camping and picnicking facilities with one special recreation area available for future use. Minor expansion of the equestrian center and marksmanship range will be implemented and repair will be undertaken at the motorcycle area. Special Protection and Educational Use Units will be designated to reserve areas for scientific study, and to protect unique features. The designation of these two new units further attests the change of emphasis of the Plan since 1966. 2. Land Use Zoning As previously mentioned. a Regional Park is to be divided into "Natural Units" and "Recreation Units". Major development is to take place in the Recreation Units. while development will be restricted in the Natural Units. The Land Use-Development Plan is shown on fig. 7. Other alternatives to the Plan are considered in Section IV.E. The intent of the Plan is to discuss land use of ACRP in general terms and to leave details concerning proposed facilities to the design phases. In order to give the public an idea of the scale and type of facility proposed. however. a brief description is given with an estimated range of numbers representing the parking or person capacity. Only detailed design study can determine actual capacities and facilities. a.

I 2. All improvements should be designed, landscaped and managed to provide an appearance that harmonizes with the surrounding natural landscape. This may require extensive maintenance because of the relatively heavy use of I Recreation Units. (page 10) I ,-_.,,~._------,----,------,,~~~_..,-~.~_..~~__,----l Recreation Units require road access and relatively flat land in an attractive setting to allow for recreational activities and scenic enjoyment. When possible, active recreation areas are located near the periphery of the Park or are separated by topography from other Park areas and designed so that active and passive recreation do not conflict. The availability of utilities is also desirable in recreational development such as water to maintain green meadows. Operation of recreation units is more efficient if connected to sewer, phone, electric, and water lines. (1) Lake Chabot Recreation Unit The existing facilities at Lake Chabot Marina will be retained. The Lake Chabot unit comprises 315 acres of lake and 35 acres of land. The entry and major facility is located off of Lake Chabot Road near Fairmont Drive. There is paved parking for 254 plus overflow space for an additional 296 cars. Lake Chabot is stocked for sport fishing and facilities include fishing piers. boat rental, sightseeing launch, paved trails for bicycles, hiking and jogging trails, an exercise station, and irrigated meadows surrounded by group and family picnic areas. A food concession is open year-round and the disabled are served with an accessible picnic facility and fishing pier. A security residence is located near the concession. Most of the land suitable for recreation development has been utilized. The existing facilities at Lake Chabot will be retained and the remaining useable areas will be utilized for additional parking, picnic and meadow area when expansion is needed. A series of approximately six family boat-in (or walk-in) picnic sites will be developed along the edge of the lake on Live Oak Island, and other sites such as Pine Point, Coot Landing, Alder Point where there is sufficient flat space for picnic tables, BBQ and trash cans. These will be serviced by boat if service vehicles cannot reach them. The eastern edge of the Lake Chabot Recreation Unit is called Marina Meadow. This is east of the existing overflow parking lot, north of Lake Chabot Road. and west of Nike Base Road and Arcadian Drive (See Fig. 9A). Marina Meadow will be left as a natural, undeveloped grass meadow, although an existing mound at the southern edge will be extended and built-up to apprOXimately 8' high to visually and acoustically screen the area from adjacent __.______.'

The mound and its edges will be planted with shrubs and trees for additional screening and privacy. The strip of land between Nike Base Road and the residences will be left clear of additional vegetation for visibility and fire protection. The meadow will be used for backup overflow parking. although no parking south of existing log barriers will take place before a meeting is held with adj acent neighbors. Public parking in this area is expected to reduce parking on nearby residential streets. including Arcadian. during high-use periods. The meadow will be mowed to accommodate parking, and the grass will alleviate possible dust problems. The need for additional parking spaces at the Marina on a typical weekend day is estimated to be about 50. This number can be accommodated west of the log barriers. The remainder of the meadow east of the barriers can contain another 150 or so vehicles. A new group reservable day use and overnight camp named Westshore Camp will be developed near Coot Landing on Lake Chabot. for use by youth groups. This area will serve a maximum of 30 people and will be a walk-in site. Two vehicles only, will be allowed to the site from Lake Chabot Road. (2) Willow Park Recreation Unit The Willow Park Public Golf Course. opened in 1965. is a l12-acre area with an IS-hole golf course. driving range and practice putting green. pro-shop, restaurant with cocktail lounge, banquet room and formal dining room, a snack bar. an outdoor wedding area. These facilities are run by a concessionaire on a 25-year lease ending in 1989 with a 2S-year extension running to 2014. The existing facilities are retained in this Plan. The course occupies the flood plain of San Leandro Creek between Redwood Road and Lake Chabot. Local flooding and siltation has occurred on the golf course during years of heavy rainfall. This siltation has damaged and interfered with golf course operations and use in recent years (refer to Resource Analysis - Hydrology). The East Bay Municipal Utility District Land Use Master Plan 1970 shows a future dam at the eastern edge of the golf course, near EBlruD's Chabot Staging Area. Should the dam be constructed. land would be removed from the golf course. If this occurred. the golf course would need to be redesigned, utilizing the little additional flat land (not including existing marsh area) that is available in this area. The existing 305-car parking lot at the golf course is now insufficient for peak use periods. (3) Grass Valley Picnic Recreation Unit Minor family picnicking facilities were previously located along Skyline Blvd. near Grass Valley Gate. The water line still remains. The picnic facilities were removed several years ago because of occasional misbehavior of some teenaged youth resulting 40 ·Fig.~,.C) ······MARINAiMEADOW..'

When funds are available, future development would be placed further from the road on ridges exposed in the 1972 fuelbreak clearing, and parking lot (s) would be locked at night. Nearby residences will be screened by landscaping to minimize any possible conflict. This location is on the edge of the vast East Bay population center and is miles from other picnic facilities (7 miles from Redwood to the north and 6 miles from Lake Chabot Marina to the south.) Based on general picnicking levels and reservation requests throughout the District, it is expected that this area would be well used for both family and group picnicking when developed. The District will develop this 39-acre area with several family or group picnic areas (serving groups of 50 to 75), including one or more gated parking lots (estimated range 50-75 cars). This area is a part of the Chabot fuelbreak. Before picnic development is undertaken, the area will be grazed. (4) Equestrian Center Recreation Unit The 12-acre Chabot Equestrian Center located off Skyline Boulevard is operated by a lessee for the EBRPD. and rents and boards horses. A Capital Improvement Plan was developed in 1966. A large parking lot and picnic area on the southernmost ridge of the area was never completed. An additional prefab boarding barn was constructed in the last several years. All existing facilities will be retained. An additional boarding barn for 25-30 horses will be built when feasible to help meet eXisting demand and increase the financial viability of the concession. (5) Bort Meadow Recreation Unit A large open flat area in Grass Valley, containing several dozen large eucalyptus trees. has been used for many years as a camp for Boy Scout jamborees. equestrian campouts. and other similar major gatherings. This area was previously called "Big Trees!' and was renamed Bort Meadow in 1980 in recognition of Joseph Bort. past Chairman of the District Master Plan Citizens Advisory Committee. Bort Meadow is a Recreation Unit and will be upgraded and improved to serve both as a reservable group camp (including one area for equestrian campers) and as a group picnic area. Design of the area in the Capital Improvement Plan may divide it into sub-units that could serve several groups at a time or one large group, but camping and picnicking groups would not occupy the area during the same time period. First come/first serve reservations will be made through the EBRPD Reservations Department. Bart Meadow is a very large (32-acre) enclosed area and isolated from other recreational facilities. It is ideal for use by a large group (1,000 persons) that could reserve the entire site. Potable and irrigation water is available at the meadow, and chemical 42 ,__,Fi"g._, r~O ",,~ __ , __ '~·.C" " '_""~'-' ..~,j _ Grass ,ValleyPicnlc'Rec..Unit.

Other park users objecting to the noise, erosion and other effects of the facility, would like the site to be closed down. In this Plan, however, the site will retain the designation of the previous 1966 Land Use-Development Plan (Master Plan) as an "existing motorcycle course to be relocated in the future. 1I When a more suitable site is found, the facility will be relocated and Chabot I s Motorcycle Hill will be closed to motorcycle use. The site ~.rill then be rehabilitated in order to reduce erosion. Any action taken by the Board of Directors on the land use of Motorcycle Hill ~Jill be considered to be a public hearing, and public input will be received. (7) Marciel Gate Recreation Unit For many years, the So-Ea-Ba Archery Club operated a range in an eucalyptus grove just north of and adjacent to Marciel Gate. The facility included a field archery range with 28 targets and a target archery facility in a large cleared area. Several sheds served storage needs. Several years ago the original clubhouse burned. Also, the euaclyptus trees were damaged as a result of the freeze of 1973-74, and eucalyptus debris on the ground and leaning dead trees remain a maj or safety hazard. The membership of the So-Ea-Ba Club has declined and the few remaining members cannot carryon the club activities or the maintenance responsibilities required. Despite the decline of the club, some maintenance has been carried on and there is regular although relatively low archery use by East Bay residents. Archery is one of the Special Interest Recreation activities appropriate in the Regional Park system. A proposed archery plan was adopted following negotiations with archery representatives in the Briones LUDP by the EBRPD Board of Directors in September 181. This Plan designated three Regional archery centers at Briones. Redwood and a site somewhere in the South Metro Subregion of the District. The purpose of the District-~Jide plan was to locate centers at dispersed sites so they would serve all residents of the District. The So-Ea-Ba facility was not designated as a Regional Center because it is close to the Redwood site. The 10-acre Marciel Gate site is attractive for recreational use because it has good access, being adjacent to Redwood Road. It has flat land for parking and recreation. Problems with the site include the eucalyptus safety problem and the lack of utilities. There is no water, sewer, electricity or telephone at the site. The nearby kiosk is served with field radio and chemical toilet only. The Plan designates this site as a Special Use Recreation Unit with no specific use designated at this time. The process to be used in selecting a proposed special group use are found in the Revenue Manual on page 85. Uses that would be considered appropriate are 46 --_ .... ---I fig. .14, Marciel ..Gat(t ~ec.· Unit. ~ Fc~ 'ff7PECtPJ F-eC:~11ON ~"""ClUTle:s b 400 eoo .1-t-l...::::::..::::{-l===t1 ~LE IN FeeT 47 found in the EBRPD Master Plan Recreation Policy, page 30. (Three recent requests for a commercial archery range. a quarter midget racing track, and survival games have been rejected for this site). Before development can take place, major cleanup of the site must be accomplished (see NRMP). This would consist of hand-clearing or prescribed burning for 2 or 3 years in succession. The District would carry out the prescribed burning, although a timetable for work in this area has not been determined. Hand-clearing would have to be carried out by any group proposing develoment. When the site is ready for development, a separate site plan and environmental document would have to be prepared by any group proposing development. (8) Marksmanship Range Recreation Unit The Chabot Marksmanship Range, leased and operated by the Chabot Gun Club, occupies a 60-acre site off of Marciel Road in a small enclosed valley. First opened in 1963 and expanded with later additions, this public range is very popular with both organized groups and individual shooters. The range provides rifle, pistol and shotgun ranges (including access for the disabled) supervised by a rangemaster. Other facilities include a security residence, snackstand, clubhouse, parking and restrooms. A proposal has been made by the Chabot Gun Club for significant expansion of the Marksmanship Range, because of the existing and anticipated regional demand for additional range facilities. The Gun Club has included in its proposal, noise abatement measures identified in two acoustical studies done by an independent acoustical consultant. (The proposal reduces acoustical impacts compared to an earlier proposal made for the 11-14-83 Draft LUDP /EIR.) The LUDP includes the Chabot Gun Club expansion proposal. However, expansion will not take place until noise levels from existing facilities have been reduced to the level of background noise at the nearby residential areas and camping facilities. (see Table 2 for the location of these areas). The Gun Club lease area will increase one-third in size (adding approximately 22 acres). The proposed additional recreation elements of the range are listed below (see Fig. 15 which shows letters referred to in the following list). Development will be financed by the Chabot Gun Club, not by District funds. All plans will be approved by the District. (a) 500-meter!600-yard range for metallic silhouette and high-power rifle competition. This feature requires grading of 38,000 c.y. (Gun Club estimate) for three locations totalling 15 acres in area; 1) a maximum of 40' of cut in the impact area; 2) fill to create a dam for the silt pond (see (j»; 3) fill to create a new firing line, with 12'-high berms (2:1) for acoustical buffering on the south and west sides of 48 FIG. 14a View of Firing Line of 5OO-m./6OO-yd.

Six-hundred feet of the Brandon Trail will be near this fill area, which will require a maximum of 40 feet of fill (including berm) see Fig. 14A. The purpose of the berm is to lOyler the noise level of the new range to a point where it will not exceed current levels. The EIR identifies additional measures to reduce the noise to below background levels. Planting of indigenous vegetation is proposed to eventually screen the fill areas. (b) IOO/200-meter small-bore range. (c) 25-yard and 7-yard pistol ranges. (d) Four trap houses and ranges for shotgun practice. (e) Ballistics tunnel for testing firearms accuracy in a crosswind-free environment. (f) Maintenance building. (g) Indoor pistol range. (h) Classroom. (i) Two parking areas. This will increase the existing 200 parking spaces (of which 100 are gravel) to 340 spaces (of which 50 are gravel with remaining spaces as dirt overflow). This plan requires extensive grading with erosion potential. Also, signifi£ant visual changes will take place (see Fig. 14A and 15) which will be seen within a small area of the park. In an effort to make this proposal more consistent with parkland values, several features have been added by the Chabot Gun Club. Miscellaneous erosion control measures, including energy dissipators, and planting of indigenous vegetation, which will be used for visual screening. Sanitary lift pump and line would be installed. This would eliminate the need for hauling of waste to campground and would replace additional chemical toilets needed for the planned expansion. Noise reduction measures will reduce noise for existing and new facilities to below background levels. Refer to Appendix D for the text of the Chabot Gun Club proposal. (9) Hilltop Camping Recreation Unit Anthony Chabot Regional Park is one of the major camping parks in the East Bay Regional Park system. It provides the opportunity for both family camping and group overnight and day camping, and will also provide backpacking camps in the future. This unit is approximately 233 acres. 50 i I ' \ : \ ' , \ \ '\ i , c: 1 . '. Anthony Chabot Family Campground The Anthony Chabot Family Campground (formerly called Las Cumbres Family Campground), is located on Las Cumbres Ridge in a eucalyptus grove overlooking Lake Chabot. It contains 73 campsites, 12 of which are trailer/RV sites with sewage hookups. Thirty-four of the sites are for walk-in use and cars must be parked in nearby parking lots. A rustic stone shelter and several irrigated meadows are located in the camp; and toilets with showers provided. Each site has a picnic table and BBQ with water nearby. Visitorship is below maximum levels, except during the peak of the camping season. A Capital Improvement Plan is needed to improve the facility. to take advantage of an existing regional camping demand to fully utilize this facility which was constructed at considerable expense. Conversion of some walk-in sites to car sites is suggested to improve campground utilization. Conversion of the eucalyptus to mixed evergreen forests is suggested, to bring in more light and improve aesthetic qualities. To improve operations and management of the campground, the existing kiosk at Marciel Gate will be relocated to the campground near Puma Point. Associated with the kiosk will be a security residence (possibly a trailer) which will oversee the kiosk entrance and a service yard. Both the residence and service yard will be located across the road from the Puma Point campsite. The original 1971 Capital Improvement Plan for the campground included additional ridgetop areas to the west and the old Toyon Hut site as expansion areas for campground. Utilities were designed and constructed for this additional use. The LUDP includes expansion of the campground into this area when demand is demonstrated by full utilization of the existing facility. Group Camps Anthony Chabot Regional Park now serves the public with six group camps available for day and overnight use on a first-come first-serve basis. Hawk Ridge was funded by the YMCA. which has an agreement for use during certain periods of the year. Five of these camps are located in the eucalYP,tus forest of Hilltop Recreation Unit. and the sixth. Bort Meadow; is discussed separately. Facilities for these camps consist of all-weather access road. water, chemical toilets, picnic tables. BBQ I sand trash cans. However; Two Rocks is in need of an all-weather road; and Lookout Ridge (previously Chabot View) needs water and grading. Hawk Ridge is the most popular camp because of its large wooden shelter and open meadow. All existing camps will be retained. Capital Improvement Plans are needed on these camps, to improve parking and recreation facilities. Maximum capacity of uses and automobiles allowed into the site are as follows: 52 .' ..

In several cases these maximum car capacities are reductions from current numbers of cars allowed at the sites. These new numbers (10 people per car) will require car pooling by large groups and the parking of autos at the Marksmanship Range and Marciel Gate Staging Areas. The purpose of this change is to reduce the amount of parking space required at the campsites. Some of these sites are quite small and recreation space is at a premium. Puma Point This site, located at the entrance to the Family Camp, is available on a reservation basis for trailer or RV groups (10-20 vehicles) and equestrian groups (20-35 horses). A Capital Improvement Plan should be implemented for upgrading the facility, including a group picnic facility for the users. This camp will also serve day camp groups. Lower Lost Ri~ A large. level area approximately 700 feet beyond Lost Ridge will serve approximately 100-120 campers and 12 cars. The all~weather road and water line between these two camps can easily be extended. An old rustic. amphitheater between the two camps will be rehabilitated. The Alameda County 4-H Club has been using Lower Lost Ridge for the past five years for an Adventure Ropes Course under a Special Recreation Use agreement with the District. This group will continue to use this area under a new five-year contract ending in 1989. The site will remain unimproved during this period of use for the ropes course. Development of the site for a group camp may take place in the future. The ropes course would be relocated if the site was needed for camping during the lease period. 54 Sunset View Another. but smaller campsite is located at the end of Sunset Trail. This will serve between 40 and 50 persons. I t. will be opened as a primitive walk-in camp until funds can be allocated for an all-weather road and water line. when it will serve five autos. An additional group camp is discussed with Bort Meadow and the backpacking camps are in the Natural Unit. Hilltop Recreation Unit Within Chabot, family picnicking is currently restricted to the Lake Chabot Marina. There are frequent requests for picnicking sites along Marciel Road, although no sites are located on the Redwood Road side of the park. A ridgetop family picnic area will be developed along the south side of Marciel Road east of the new kiosk of the campground, and along the adjacent ridge containing the Live Oak Trail. Approximately 25 to 30 family tables will be provided with an equivalent number of parking spaces. Native trees will be planted to provide shade, and irrigated meadows may be developed. A small spur road may extend a short way onto the ridge for access. Parking may be located parallel to the roadway. (10) Maintenance and Operations Service Areas The South County Service Unit above Lake Chabot includes the EBRPD Public Safety Headquarters, South County Class Room, South County Service Yard and Lake Chabot Service Yard. These facilities will be retained. A fire house, housing 2-3 vehicles, an office, restrooms and workshop, will be constructed to serve the southern Alameda County Regional parklands. The equipment shops will be expanded and a storage and covered parking area will be constructed. A capital improvement plan is needed for this area. The entire area is approximately 19 acres. An Anthony Chabot satellite service yard (not serving the Marina area) will be constructed near the entrance to the Family Campground across from Puma Point. This facility will eventually include office/shops, etc., and an enclosed yard. Specific facilities for the service yard will be determined in the Capital Improvement Plan. It will be associated with a security residence and entrance kiosk. The Redwood zone service yard will continue to operate as a zone service yard and will contain some equipment not available at Chabot. 55 b. Natural Unit EBRPD MASTER PLAN Planning and Management Guidelines - Natural Areas 1. The purpose of this designation is to assure protection of natural features and values within a significant portion of a Regional Park. 2. The primary management objective is to allow only activities which are compatible with the natural environmental values while preserving, or restoring where necessary, scenic. near-natural landscape conditions. 3. Development should be limited primarily to making the natural area available for public enjoyment in a manner consistent with the preservation of natural resource values. Development may include such things as basic. but not elaborate. improvements necessary for camping and related outdoor activities, hiking, nature study and horseback riding. 4. A Natural Area may contain a Regional Preserve or a Trail Link, which should be planned and managed according to applicable guidelines. A Natural Area may contain peripheral access staging facilities for internal trails. 5. Forest and land management techniques such as tree cutting. controlled burning. reforestation and planting programs using indigenous plant materials. and livestock grazing may be used to preserve, maintain or recreate the desired environmental setting. (page 10) The Natural Unit includes all other areas of the parkland not designated as Recreation Units, and includes the Special Protection and Educational Use Units. The vast majority (approximately 81%) of the parkland will be the Natural Unit, where development is limited to preserve the Park's natural features and qualities. This area contains a variety of wildlife habitats, topographical units and scenic areas. The major features are the Grass Valley watershed with surrounding Chabot and Skyline Ridges. This area will be free from the intensive use associated with recreational facilities. except for a fe~l areas where recreational units will be located within it. It provides quiet, undisturbed space for hikers. equestrians and picnickers, and those who seek a quiet alternative from their urban environment. (See Fig. 7). Staging requires level space for parking, road and trail access and should be located at the periphery of the Park. As in recreation units, operation is sometimes more efficient if utility service is available. Chabot is almost entirely surrounded by public roads. but utility service is limited. Useable flat areas are limited along the road-lined edge of the Park but a significant amount of flat useable open space areas occur on interior ridge tops and in Grass Valley. 56 (1) Educational Use Units These are areas within parklands identified by the District Educational Use Committee as appropriate for the study of natural. archaeologic. and historic features by University and College faculty and students, high schools, and professional and amateur researchers. It is contemplated that sample areas of each of the major ecological communities to be found within District lands will be available for study within designated units. ~D MASTER PLAN I Educational Use Area Policy 1 1. The District will designate selected areas within various I regional parklands as Educational Use Areas, where faculty or advanced students of universities and colleges and I other research organizations within the District are II encouraged to conduct ongoing or periodic studies. and . where they can be assured of the long-term status of such use. 2. When the Land Use-Development Plan of the pertinent parkland is prepared. any such Educational Use Area in that parkland will be incorporated into the plan, insuring maintenance of the integrity of the natural resources for which the Use Area was established. 3. Group use of such areas will be limited to educational i purposes and may include projects by individuals or organizations representing university. college, high school, interested professionals, and amateur researchers. provided the ongoing research is not thereby disrupted. 4. Selection of and subsequent regulation of USes at Educational Use Areas will be with the advice of an adVisory committee whose members represent university. i college faculty and others appointed by the Board of I Directors. Research proj ects will be focused on field studies of geological or bio-ecological features which the East Bay Regional Parklands prOVide in greater degree or accessibility than most other properties in the region. It is contemplated that sample areas of each of the major ecological communities to be found in the District lands will comprise most of these Use Areas. 5. Use of Educational Use Areas for research or group education will be by permit through the General Manager. In each Educational Use Area this may involve strict limitations on the alteration. disturbance, or removal of plants, animals, or any other natural feature that is allowed during such use. (page 34) '------, ---_._._-----_.. _-_.--,------'------ 57 Three units have been selected by the EBRPD Educational Use Committee in ACRP: E-l This areaa is important for 1) r,ative grasses on Nike Hill and Tule Overlook and 2) developing marshland at Frog Flats. Frog Flats has been filling in gradually but continually since the lake was created. with deposits from San Leandro Creek. The marsh development was accelerated during the drawdown for the repair of Chabot Dam. E-2 This area is located within one of the largest eucalyptus stands in California and includes a small stand of mixed evergreen forest. E-3 The third unit contains the southernmost natural stand of redwood trees in the East Bay. It is also designated to study the succession of grassland into brushland. (2) Special Protection Units These include any area within a parkland containing: outstanding natural features; rare or endangered plant and animal species, and their supporting ecosystems; selected samples of each plant and animal community occurring naturally in the District; significant geologic. topographic. hydrologic or scenic features; archaeological sites; historical structures; or blue-line streams as shown on USGS maps and other designated water courses. which. in the context of all District resources. warrant special protection management policies. EBRPD ~illSTER PLAN Environmental Preservation Zones There may be areas within all parkland classifications which contain outstanding natural features. rare or endangered plant and animal species and their supporting ecosystem. significant geological. topographical features or have structures of historical significance. Because of the unique and potentially fragile nature of these areas. Special Protective Zones shall be identified in the Resource Analysis and designated. in the Land Use-Development Plans for each parkland. The primary objective of these Special Protection Zones is the preservation and enhancement of significant resources. Development within the Special Protection Zone shall be held to the minimum required for public safety protection and enhancement of the resource. Detailed restrictions of each Special Protective Zone shall be included v.!ithin the Land Use-Development Plan of each pa.rk. Prior to completion of the prescribed planning process, Environmental Preservation Zones may be designated by the Board without benefit of a completed Resource Analysis or Land Use-Development Plan to protect sensitive areas. (page 33) 58 S-1 This unit is a great blue heron rookery. Public access is restricted and prescribed burning is to be carried out only outside of the spring breeding season. 8-2 This unit is an area which supports a population of western leatherwood. It is to be excluded from any prescribed burning. 8-3 This unit provides habitat which appears suitable for the Alameda striped racer snake. Prescribed burning is to be carried out only during the fall when these animals appear to be less active. Thus, they are more likely to be in an underground burrow and survive a fire. 8-4.5 These units include reported localities of the Diablo rock-rose, Oakland star-tulip and fare-well-to-spring. Prescribed burning is to be carried out only outside of the spring seed producing period. 8-6 This unit is an area which supports a population of western leatherwood. It is to be excluded from any prescribed burning. (3) Park Staging Areas There are several staging (parking) areas located around the edge of the park which provide parking and trail access. These are adjacent to or completely separated from the previously discussed recreation units. All existing staging areas will be retained. Macdonald Staging Area (20 cars and trailers) Bort Meadow Staging Area (30 cars at Redwood Road) Marciel Gate Staging Area (40 cars and trailers at Redwood Road) Brandon Staging Area (10 cars) Ten Hills Staging Area (16 cars and trailers previously called Proctor Gate Staging Area) Grass Valley Staging Area (formerly Chabot gate 20 cars) Chabot Staging Area (EBMUD - Upper San Leandro Reservoir) also serves ACRP No additional staging areas will be constructed. unless associated with a planned recreation facility. Capital Improvement plans are needed for several of the staging areas, particularly Ten Hills Staging Area. (4) Public Park Roads and Entry Kiosk Several public roads surround the park. and provide good access. (Some of these coincide with the park boundary.) Within the park there is only one significant in-park public road. It is the 3. S-mile-long Marciel Road. which runs from Marciel Gate to the family campground. Two side roads. to the Marksmanship Range and 59 group camps, branch off from it. These roads will be retained in the Plan. Capital improvements should be undertaken to correct existing problems with the road. A minor road. Nike Base Road, approximately 4/5 of a mile long, goes from Lake Chabot Road to the South County Service Yard. The park's only entry kiosk is located at Marciel Gate. From it, park staff accepts fees for the family campground, directs park users. provides public information, and discourages "Sunday driving" in the park. The kiosk is open on a part-time basis, primarily during the periods of heavier use. During off-hours. family campers must drive at least five miles to phone Public Safety for the gate lock combinations to get into the park at the Brandon Staging Area. Park workers then collect fees the next morning. Group campers and marksmen need not stop at the kiosk and are sometimes required to wait in long lines behind trailers paying fees. There are no utilites other than a chemical toilet and communications radio at the kiosk. It is an isolated facility which could pose a possible hazard to a lone employee working there. Conversely. it can assist drivers with problems (on Redwood Road) through the use of its radio. The kiosk will be relocated to the campground entrance to better serve its main function of fee collection. It will be placed in conjunction with a new service yard and security residence near Puma Point Camp. (5) Park Trails A major recreational use of the Park has been. and is expected to continue to be, hiking and riding on the extensive trail system (approximately 40 miles). The large-scale open space park provides an opportunity for District residents to get away from the urban areas while really being very close to them. In general. the Plan maintains this basic system. Construction of a few non-vehicular trails will complete the trail system. Hiking/Riding/Service Trails The majority of trails in the park, the hiking/riding/service trails, will continue to be the backbone of the Chabot trail system. All existing trails will remain. Some trail construction will be implemented to complete the existing deadend trails. These are: northern end of the Goldenrod Trail (formerly Skyline Tr.) - northern end of the Grass Valley Trail (formerly Central Trail) 60 Until recently, the west edge of Lake Chabot (between the dam and Columbine Trail) has been off-limits to park users, thus making a circuit around the lake impossible. A new agreement was reached several years ago with East Bay Municipal Utility District making the loop trail complete. The trail was opened in the Summer of 1983 after remedial trail construction was completed. "Stay-on-the-trail" restrictions near the dam and Lake Chabot Municipal Golf Course are in effect for the protection of park users. The newly opened trail is called Bass Cove Trail. The majority of trails used by hikers and equestrians are dirt roadways suitable for service and fire vehicles. These trails generally run through grassland or eucalyptus areas, while a few are within woodland areas. Because of the necessity of providing service and fire protection, these trails predominate through the park and receive first maintenance priorities over narrow trails. Fire protection in the park is provided by EBRPD, California Department of Forestry, and the Oakland Fire Department. A minimum road width of 10 feet is required on straight, flat runs, 12' on a straight but steep side hill situation, with wider areas needed at curves. Many of the existing trails are wider. For a more natural, aesthetic look, these will be reduced in size. The LUDP hiking/riding/service trails will be consistent with the official fire trails map for Chabot. Hiking/Riding and Hiking Only Trails Some trails in ACRP are designated for hiking/riding or hiking only, where steep terrain is encountered. They are to be maintained at a maximum 4-foot width and minimum 18-inch with hand labor and small equipment. These trails are described by some park users (generally hikers and equestrians) as the most scenic and enjoyable trails within the parkland, and additional narrow trails have been requested. particularly in areas now inaccessible. In the past, ACRP has suffered in comparison with other Regional parks. such as Redwood. because of the lack of scenic trails in areas of native vegetation, particularly the mixed broadleaf forests. Most of the existing ACRP trails are within dense euaclyptus forest or in grassland. Thus, three new trails (Grey Fox, Oracle Oak and Woodland Trail) will be constructed to take park visitors into these more scenic areas. Jogging/Bicycle/Service Trails Joggers and bicyclists have different needs from the hikers and equestrians. Bicyclists prefer paved roads and require a wider width because of their relatively faster speeds. Joggers also prefer gentler grades than hikers and equestrians, although many prefer dirt surfaces. In addition, most joggers prefer loop trails which are accessible to staging (parking areas) • Existing Westshore and Eastshore Trails along Lake Chabot are paved and are designated as multi-purpose trails. No additional paved trails 61 will be constructed. The recently built McGregor-George Trail was constructed for joggers and terminates at an exercise station at the Lake Chabot Marina. No additional dirt trails are proposed which would be particularly suitable for joggers. There are a few trails within the parkland that do not fit into the above categories. Horses are not allowed on paved trails around the lake (Westshore Trail, Eastshore Trail). The Cottontail Trail, when constructed, will be an " a ll weather road" to accommodate service vehicles. The all-weather surface will extend from Marciel Road at Marciel Gate to Grass Valley Gate. Private autos will not be allowed on this route. EBRPD MASTER PLAN Trail Policy The District, in coordination with other governmental agencies in the two counties, will acquire, develop and operate a Regional Trail System with the overall obj ective of providing a comprehensive system of trails through and connecting its parklands with each other and with other trail systems as well as the urban communities. To this end, the Two-County Regional Trail Plan adopted by the District June 20, 1972, and as amended on October 5, 1976, is hereby amended and is found in this revised Master Plan on page 20. (page 32) A major trail running through the length of the Park is identified on the Plan as the East Bay Skyline National Recreation Trail, and includes the Macdonald, Grass Valley, Redtail, Brandon and Willow View Trails (see Fig. 7). This reroutes the present alignment off of the Redtail Trail (formerly Valley Trail) and part of the Brandon Trail to take advantage of more scenic areas and to connect into the Chabot to Garin Regional Trail. When the Grey Fox Trail is constructed. the regional East Bay Skyline National Recreation Trail shall be rerouted to that more scenic location. Services Along Trails Many people have expressed the desire for the District to place picnic tables, toilets and water fountains/troughs along the trails in the park, especially for park users who are on long hikes. Such facilities will be located within the Park at reasonable intervals where: there is adequate access for maintenance vehicles; at locations where there are springs or waterlines, making them economically feasible; and at locations where vandalism is not expected to be a problem. The construction of several facilities outlined in the Plan will provide water and toilets at appropriate locations in the parkland to serve several of the trails as well. 62 __,_ ... .__.__,_ Fig.... __ 1':~8 .-BEGI.ONIL,~:ttlAILS:PLAN- ~ A Existing or EIR adopted Potential . 16.

(6) Local Access Points and Gates Additional local access points with no parking facilities are available for local residents to walk; jog or ride into the Park (and for park vehicles). The McGregor-George trail is located at the southern edge of the Chabot Marina. An entry at the end of Parkridge Drive goes into the park at Natural Dam. Trail access into the Park is available at Chabot "City Park" at the end of Estudillo Avenue. An additional access at Grovenor Road has been closed for many years as a result of desires of the neighbors. The Plan does not call for the reopening of this gate at this time. (7) Backpacking Camps Small backpacking camps (6 to 10 people) in the interior of the park (away from areas of more active recreation) will be established for the use of families and small groups of backpackers. (See EBRPD Trail Manual, 1976). These camps will be reservable for one night only per group and are designed to serve hikers who are on a trek from one Regional Park to another; utilizing the Regional Trail System. EBRPD MASTER PLAN Camping Policy The District will provide overnight camping facilities, including those for overnight stops on continuous hikes, for organized groups as well as for individuals. As the need presents itself. the District will consider the provision of rudimentary shelters. These shelters will be designed to provide sufficient protection from the elements so that campers will need little more than a sleeping bag for an overnight stay. (page 31) Two backpacking camps are proposed for ACRP. These may be located in a number of good sites throughout the Park and may be rotated to avoid injury to vegetation and other resources or to permit restoration if damage occurs. These camps will be located near service trails and will be identified by a camp name sign with an attached reservation card listing the reservation parties. Several small groups may be booked into one campsite at the same time to reach the maximum capacity of the camp. Facilities will include chemical toilets and possibly a shelter. No trash cans will be provided as campers will be asked to carry out what they carry in. Water will be provided. if possible. otherwise hikers will have to carry it in. No horse facilities will be provided. (See Bort Meadow and Puma Point for equestrian facilities.) No fires will be permitted. 64 Corral Camp An old group campsite between Bort Meadow and Stone Bridge on Grass Valley Trail will be the site of one backpacking camp. Repair of an old water line and the planting of shade trees may be included. It will serve approximately 12 campers. Acorn Hollow A flat area at the end of a ridge on Loggers Loop will be a second packpacking camp. It will serve approximately 12 campers. Additional Site If there is sufficient demand, an additional site may be added within the parkland. D. FUNDING AND SCHEDULES Implementation of this plan is expected to proceed in phases. some of which may not be undertaken for many years. This plan is long-range in nature and user demand must increase in some cases before development will be contemplated. Also. funds must be budgeted for each project, and development funds for Chabot must be balanced against the other parks and priorities of the Park District. Development of Bort Meadow and a service yard has been anticipated for many years as a part of the 1966 Capital Improvement Plan. and budgeted funds for these two projects may be carried over to the 1984 budget. In 1983, $54,274 was reserved for development of Bort Meadow and $78,125 was designated for the service yard. Upon the adoption of this Plan and in coordination with a Capital Improvement and Restoration Plan, grant funds for the Redwood Road Motorcycle Recreation Unit will be sought from the Off-Highway Vehicle Grants Program through the California State Department of Parks and Recreation. Other grants that may be applicable will be investigated. E. PLAN ADMINISTRATION AND IMPLEMENTATION Upon adoption by the Board of Directors, this Plan shall be implemented under the direction of the East Bay Regional Park District General Manager vs office. In areas where land ownership or use permits are incomplete, purchase, dedication, or agreements shall be administered by the Land Acquisition Department. Design, development, working drawings, permits, environmental review, and contract administration shall be the responsibility of the Planning and Design Department. Development plans and specifications for specific areas shall be approved by East Bay Municipal Utility District and South County Community College District. Maintenance of the existing and proposed facilities shall be by the Anthony Chabot and Lake Chabot crews and special District crews, and be under the supervision of the Park Supervisor and Zone Manager. The area between Natural Dam and Redwood Road may at times be maintained by the 65 Redwood crew. (See Chapter I, Boundary Alterations.) The Park Supervisor is responsible for seeing that maintenance and small construction projects are consistent with the adopted Plan. Any questions regarding this consistency shall be discussed with the Chabot Project Manager, a Landscape Architect of Planning & Design. Maintenance work on grading, drainage, roads, structures, fencing, pond, creek or spring work and work in special protection units, etc., will be performed under direction of the appropriate specialist. such as Engineer, Water or Land Management or Grazing Specialist, Resource Analyst. and Environmental Coordinator. Any maintenance work involving design or layout changes shall be approved by a District Landscape Architect. Reservations shall be through the EBRPD Reservations Department. Special Interest Recreation license agreements, grazing leases. concession agreements and security residence agreements shall be negotiated and managed by the Revenue Operations Branch of the Parks and Interpretation Dept. The progress of the implementation of the Plan shall be reviewed annually as part of the Coaching Plan of the Park Supervisor and crew. The Chief of Planning and Design shall establish a priority order for development of the proposed facilities requiring capital expenditure, and shall also annually review the Plan implementation and establish capital projects utilizing any development funds that may become available. Inventory of Park resources and facilities shall be maintained by the Planning and Design Department in cooperation with other departments. F. REVISIONS TO THE PLAN 1. Amendments to Plan/EIR and Major Park Developments The Land Use-Development Plan will be amended as conditions change and as needed. These amendments will be developed by the EBRPD Planning and Design Department and presented to the EBRPD Board for adoption. Amended Plans will have the appropriate CEQA work, as determined by the Environmental Coordinator. and will be adopted by Board resolution. 2. Corrections and Minor Park Development Minor corrections or minor Park developments not on the Plan that are identified by the Park crew or others, shall be discussed with a District Landscape Architect. A written letter to the file stating the changes and signed by the Chief of Planning and Design shall be filed with the originals of the Plan/EIR for future reference. Public suggestions for changes to the Anthony Chabot Regional Park Land Use-Development Plan shall be directed to the Assistant General Manager and he shall assign action to the appropriate department, if necessary. These suggestions shall be filed with the LUDP originals for future reference. 66 IV. NATURAL RESOURCES MANAGEMENT PLAN A. GENERAL Anthony Chabot Regional Park (ACRP) is a large open-space parkland which has been substantially affected by human activity. These influences require a future commitment for significant resource management efforts to stop erosion, prevent uncontrollable wildfires, maintain landscaped areas. and support a recreational fishery. Many people imagine ACRP to be a "natural" parkland and others appear unable to recognize the substantial adverse effects associated with the form of recreation which they pursue there. This leads to an attitude that existing conditions are satisfactory. An obj ective survey of ACRP leads to a conclusion that active resource management is required to correct past mistakes and prevent future damage to the park's resources. The following segments outline both management objectives and the policies needed to accomplish them. Where these policies represent a choice from among several options, and where no previous policy guidance has been given by the Board, a rationale is presented. B. VEGETATION 1. Landscaped Areas Objectives These are; to provide landscaped areas to accommodate a golf course and informal sports in camping and picnicking areas and to implement District land resource policies regarding pest plants in a manner consistent with the EBRPD environmental hazards policy, (Master Plan, 1980, p. 34). Policies The District will provide irrigated meadow areas and associated landscape plantings for informal lawn sports near maj or picnic and camping areas. The District will encourage the operators of the Willow Park Public Golf Course to use integrated pest management as part of the maintenance of the golf course and will actively review and approve future pest management practices. 2. Grassland Objectives These are; to maintain a significant portion of ACRP in grassland vegetation. 67 to preserve the park's grasslands in a condition which promotes a diverse flora, including those grassland herbs which have been proposed for protection as rare or endangered and to promote scientific study of ecological succession in grassland. Policies The District will maintain grassland as the primary vegetative cover in the southeasterly portion of Grass Valley (See Fig. 19). The primary method of brush removal will be by the repeated use of prescribed fires or by mechanical crushing plus prescribed fires; however, where the safe use of prescribed fire is not possible, mechanical equipment, the introduction of goats and/or hand labor will be used initially to remove the brush. The District will develop specific criteria for identifying such areas. This area will be maintained as grassland by fencing it, developing water sources and introducing livestock. The District will preserve existing grassland in the Cow Hollow portion of ACRP by continued grazing with livestock. The District will preserve other existing grassland areas as shown in Fig. 19, by the use of prescribed fires, the introduction of livestock, or by the institution of haying operations. The District will set aside certain grassland areas where ecological succession from grassland to brushland is occurring for the scientific study of this phenomenon. These reserved areas are within the northerly and southerly educational use units (see Fig. 7). Vegetation management will include reduction of fuel levels on slopes with urban development on the ridgecrest above, using prescribed fires. Rationale The policy to maintain portions of ACRP as grassland is recommended to maintain a significant amount of grassland and to preserve a diverse flora and fauna. The Grass Valley area very probably has been a grassland since the end of the last ice-age, due to the combined effects of grazing by large mammals (first by tule elk, and later by cattle) and the periodic occurrence of wildfires (caused first by lightning and later the increased frequency of fires caused by human activity). With the cessation of grazing and the prevention of fires which resulted when the land was acquired by the EBRPD, brush invasion of the grassland has occurred. Portions of Grass Valley (north of Bort Meadow) are reco1Il1llended to be set aside for the scientific study of this process, similarly, portions are recoro.mended to be maintained as grassland to preserve diversity and historic context. The specific areas defined for preservation were selected because grassland can be maintained as the primary vegetative cover with the least visual change from current (1983) conditions. The policy to use livestock as a method of preserving grassland is recommended because 68 livestock grazing would approximate prehistoric vegetative conditions. These conditions cannot be exactly duplicated because of the abundance of non-native grass species and the extremely low numbers of tule elk. The use of domestic livestock for this purpose will provide an annual removal of excess grass biomass produced by the non-native annual grasses. Without such a removal. thatch tends to build up and inhibit the growth of the native grassland herbs. These herbs are adapted to growing in the openings between the native perennial bunch grasses; however, the thatch from the non-native annual grasses closes in the openings between grass plants. Among the native herbs of concern here are three species which have been proposed for protection as rare or endangered species. If. alternatively, this grassland were to be managed with prescribed fires alone, a thatch of annual grass \I.'Ould build up in the years between the prescribed fires. This is not as desirable a circumstance for the native herbs as an annual removal pattern. The policy to use prescribed fires. livestock or haying operations to preserve certain smaller existing grassland areas is recommended because these areas are somewhat isolated. Thus, the most cost-effective method of maintenance may change over time. The policy was worded to provide staff flexibility in dealing with changing costs. The policy to set aside certain areas where grassland will be allowed to succeed to brushland is recommended upon the advice of the EBRPD Educational Use Committee. The Cowmittee has indicated that the use of prescribed fires to reduce fuel levels on slopes with urban development above is consistent with desirable educational uses as long as researchers are informed of burning schedules and can make observations before and after such fires. 3. Brushland Objectives These are; to maintain brushland areas in a way which reduces the potential for wildfires spreading from them into adjacent developed areas, to preserve the brushland in a condition which promotes a diverse flora as nearly representative of the natural occurrence of this association as is consistent with existing recreational use commitments and to promote scientific study of brushland. Policies The District will cooperate with other adjacent land owners to extend a variable-width fuelbreak using mechanical equipment, the introduction of goats and/or hand labor along the crest of Skyline Ridge from its present northerly terminus north to Redwood Road. Maintenance of the fuelbreak will be carried out in accordance with the EBRPD Fuelbreak Maintenance manual. 69 The District will reduce the fuel levels on brushland slopes, which have residential or other structures on the crest above, using prescribed fires. The District will conduct occasional prescribed fires in the brushland areas for the purpose of long-term preservation and enhancement of this plant association. The District will set aside certain brushland areas where ecological succession from brushland to mixed-broadleaf forest is occurring for the scientific study of this phenomenon. The reserved areas are in the northerly and southerly educational use units (see Fig. 7). Vegetation management will be limited to the reduction of fuel levels on slopes with urban development on the ridgecrest above using prescribed fires. Rationale The policy to extend a variable-width fuelbreak northerly from its present terminus to Redwood Road is recommended because of the residential development located on the ridge crest immediately above the brush-covered slopes of Skyline Ridge. The relative position of brush and houses could lead to severe damage or destruction of the houses in the event of a wildfire. This policy was recommended by the Blue-Ribbon Fire Prevention Committee whose report has been accepted by the EBRPD Board. The policy to use mechanical equipment, goats and hand labor to construct the fuelbreak is recommended because it would be cost-effective compared to hand-clearing exclusively and because prescribed fire cannot be used for fuelbreak construction in areas proximate to residential development with complete assurance that it would not damage the houses. The policy to use prescribed fire for fuel reduction and vegetation 1nanagement in brushland is recommended because this method more closely approximates natural processes and is more cost-effective on a prepared site than mechanical clearing or the use of herbicides. The extensive use of prescribed fires has not been attempted previously by the EBRPD. Thus, various "prescriptions" will be tested initially to determine which might best meet the District's objectives. In order to prepare an area for a safe prescribed fire, mechanical equipment, the introduction of goats and/or hand labor may be needed. The policy to set aside certain areas where brushland will be allowed to succeed to mixed-broadleaf forest is recommended upon the advice of the EBRPD Educational Use Committee. The Committee has indicated that the use of prescribed fires to reduce fuel levels on slopes with urban development above is consistent with desirable educational uses as long as researchers are informed of burning schedules and can make observations before and after such fires. 70 4. Mixed-Broadleaf Forest Objectives These are; to preserve the mixed-broadleaf forest areas in a condition which is representative of the natural occurrence of this association and to promote the scientific study of the mixed-broadleaf forest. Policies The District will remove eucalyptus trees which occur within the primarily mixed-broadleaf forest in the area shown in Fig. 19. This removal may be accomplished with a license between the District and a private timber operator. The remaining stumps will be treated with a chemical, approved by the District, to kill them. The District staff will fell and treat isolated eucalyptus trees in the mixed-broadleaf forest which cannot be economically removed by a timber operator. The District will set aside certain mixed-broadleaf forest areas for scientific study. The reserved area is in the central educational use unit (see Fig. 7). Vegetation management will be limited to the removal of eucalyptus trees as described above. Rationale The policy to remove the eucalyptus trees from the mixed-broadleaf forest is recommended to preserve the natural occurrence of this association. The policy to consider the use of a private timber operator to perform this work is recommended as a cost-effective method of obtaining the skilled labor needed for this work. The policy to treat the stumps with an approved chemical is proposed as a cost-effective method of quickly killing them. The policy to fell isolated trees and treat them is in accordance with the adoped policies of the EBRPD Vegetation Managment manual. The policy to set aside certain mixed-broadleaf forest areas for scientific study is recommended upon the advice of the EBRPD Educational Use Committee. The Committee has indicated that the removal of eucalyptus trees in this plant association is consistent with the desirable educational uses. 5. Eucalyptus Groves Objectives These are; to establish and maintain. conditions in all the eucalyptus groves which mitigate against uncontrollable wildfires, 71 to maintain the functions of education, isolation and noise control currently provided by the eucalyptus groves numbered 3, 4, 7, 8 and 9 which are near the Marksmanship Range, the campgrounds, the group picnic areas and the central educational use unit, to manage the eucalyptus groves in a cost-effective manner with the eventual obj ective of establishing indigenous vegetation in their place and to promote scientific study of eucalyptus groves. Policies The District will establish a series of fuel and fire breaks between the eucalyptus groves, as shown in Fig. 19. This may be accomplished with a license between the District and a private timber operator. The remaining stumps will be treated with a chemical, approved by the District, to kill them. Maintenance of the fuel breaks will be carried out in accordance with the EBRPD Fuelbreak Maintenance manual. The District will reduce fuel levels in all eucalyptus groves using prescribed fires and in groves numbered 7, 8 and 9 selective thinning may be used on an occasional basis. The District YTill harvest timber products on an experimental basis from certain of the eucalyptus groves. The District Land Management Specialist will prepare a timber harvest plan for this purpose beginning in grove number 1 (Fig. 19). This harvest may be accomplished with a license between the District and a private timber operator. The trees will be allowed to coppice, i.e., the stumps will resprout. The interval between harvests of the same block will be between 5 and 20 years. This harvest pattern, intended to result in the eventual decline and death of the eucalyptus trees, will be replaced by volunteer indigenous trees which will not be included in the timber harvest. If there are substantial pockets of indigenous forest within a harvest area (one acre or more), the eucalyptus trees harvested around its periphery will be treated with a chemical, approved by the District, to quickly kill them (see also policies under the mixed-broadleaf forest). If the experimental harvest is successful in converting to indigenous vegetation, it also will be pursued in groves numbered 2. 5, and 6 (Fig. 19). The District will set aside eucalyptus grove number 4 for the scientific study see Fig. 19). Vegetation management will be limited to the use of prescribed fire to reduce the accumulation of fuel on the forest floor to desirable levels, and the removal of vegetation which may present a hazard to park users. Rationale The alignment for the fuel breaks was determined based upon the recommendations of Mr. Roger Fenwick. a consulting fire ecologist, with expertise in managing eucalyptus trees both in California and in 72 Fig. 1 9 FUEL BREAK l MANAGEMEN' 1t PLAN LEGEND: ~Experimental Eucalyplus·Harv9st "..Unharvested Eucalyptus ~Groves ••• Fuel Break Forest Grassland Preservation " t Grassland Study Areas Australia; his recommendations have been reviewed and approved by the District Fire Chief. The policy to consider the use of a private timber operator to perform this work is recommended as a cost-effective method of obtaining the skilled labor needed for this work. The policy to treat the cut trees with an approved chemical is proposed as a cost-effective method of quickly killing them. The policy to use prescribed fire for fuel reduction and vegetation management in eucalyptus forests is recommended because there is an excessive accumulation of fuel on the forest floor (the equivalent of 16 cords of wood per acre). This method more closely approximates natural processes and is more cost-effective on a prepared site than mechanical clearing The extensive use of prescribed fires has not been attempted previously by the EBRPD. Thus. various "prescriptions" will be tested initially to determine which might best meet the District's objectives. In order to prepare an area for a safe prescribed fire. mechanical equipment. goats or hand labor may be needed. The policy to harvest timber products from certain eucalyptus groves is recommended as a cost-effective method of maintaining these groves so that all of the trees are not of the same age and so that there is the possibility of future conversion to indigenous forests. It is intended that the recommended harvest pattern eventually will exhaust the trees and convert the eucalyptus groves to indigenous vegetation in accordance with the adopted policies of the EBRPD Vegetation Management manual. An income also will be produced to partially support the costs of other maintenance activities within ACRP. including the costs associated with the maintenance of fuel breaks and the maintenance of acceptably low levels of fuel within all of the eucalyptus groves. At the same time, some eucalyptus groves (i.e. groves numbered 3, 4, 7, 8 and 9) will be allowed to mature. die and reproduce without timber harvest activity. It may be that such a management pattern eventually will result in conversion of these groves to indigenous forests. The presence of indigenous tree species in the forest understory suggests that such a conversion may result. Since there is no way of predicting which management approach will be most successful in converting the eucalyptus plantations to indigenous vegetation, both approaches are recommended simultaneously. The policy to consider the use of a private timber operator to perform this work is recommended as a cost-effective method of obtaining the skilled labor needed for this work. An alternative method of establishing indigenous vegetation is to remove the eucalyptus trees and either physically remove or chemically treat the stumps. stump sprouts and seedlings which grow after removal. Such a program was not recommended because it would not be cost-effective. and would not be consistent with other objectives relating to vegetation. wildlife, and soil. The policy to set aside certain eucalyptus plantation areas for scientific study is recommended upon the advice of the EBRPD Educational Use Conmittee. The Committee has indicated that the use of prescribed fires to control fuel levels on the forest floor is consistent with desirable educational uses as long as researchers are informed of the burning schedule and can make observations before and after the fires. 74 6. Riparian Woodland Objectives These are; to preserve the riparian woodland areas in a condition which is as nearly representative of the natural occurrence of this association as is consistent with existing recreational use commitments and to promote the scientific study of riparian woodland. Policies The District will allow all areas of riparian woodland to persist and increase in extent without active management, except for the portions of San Leandro Creek which are within the Willow Park Public Golf Course. Within the existing golf course, the characteristic trees will be maintained, however. the understory vegetation will continue to be managed in a manner which is consistent with golf course use. The District will set aside a riparian woodland area for scientific study. The reserved areas are in the southerly educational use unit (see Fig. 7) • Vegetation management will be limited to minor clearance of vegetation to maintain the trail and sewerage pipeline which passes through this area. The District staff will fell and treat isolated eucalyptus trees in the riparian woodland which cannot be economically removed by a timber operator. Rationale The policy to set aside certain riparian woodland areas for scientific study is recommended upon the advice of the EBRPD Educational Use Committee. 7. Aquatic and Emergent Vegetation Objectives These are; to preserve areas of indigenous aquatic and emergent vegetation in a condition which is as nearly representative of the natural occurrence of this association as is consistent with existing recreational use commitments and to promote the scientific study of aquatic and emergent vegetation. Policies the District will allow all areas of indigenous aquatic and emergent vegetation to persist and increase in extent except for the portions of Lake Chabot in and around the Marina complex. Within the Marina area aquatic and emergent vegetation may be removed as part of the dredging and maintenance operations needed to assure continued operation of the Marina. (The East Bay Municipal Utility District. 75 which owns Lake Chabot, has the right to continue its past algae control practices to assure drinking water supplies. It is anticipated that they will continue to do so.) The District will set aside an area for the scientific study of aquatic and emergent vegetation. The reserved area is the Frog Flats area in the southerly educational use unit (see Fig. 7). Vegetation management will be limited to minor clearance of vegetation to maintain the trail and sewerage pipeline. which passes through this area. Rationale The policy to set aside certain areas of aquatic and emergent vegetation for scientific study is recommended upon the advice of the EBRPD Educational Use Committee. 8. Exotic Vegetation Objectives These are; to return areas now planted with exotic vegetation to indigenous vegetation without adversely affecting the recreational uses which may take place near them. Policies The District staff will not take further actions to plant or nurture non-indigenous vegetation. The District staff will, incidental to their other activities, take actions to discourage and prevent the reproduction of non-indigenous vegetation within ACRP. Rationale The policy to cease planting and nurturing activities for non-indigenous vegetation is recommended as a cost-effective method of eliminating exotic vegetation which does not reproduce in ACRP. This represents a reversal of the previous policy of afforestation within ACRP. Existing exotics which do not in general reproduce (e.g.• Monterey pine, and fruit trees) will mature and die over a period of time and thus be eliminated. This policy is in accordance with the adopted policies of the EBRPD Vegetation Management manual. The policy to discourage and prevent the reproduction of exotic vegetation as an incidental part of other maintenance activities is recommended as a cost-effective method of containing exotic vegetation which reproduces in the park (e.g•• eucalyptus trees. acacia trees and pampas grass). This policy is in accordance with the adopted policies of the EBRPD Vegetation Management manual. 76 9. Jeopardized Plants Objectives These are; to manage the plants and animals in ACRP in a manner which will maintain existing populations of the western leatherwood (Dirca occidentalis). fare-well-to-spring (Clarkia rubicunda rubicundia) and Oakland star tulip (Calochortus umbellatus); and to create conditions conducive to populations of other jeopardized plants such as the Diablo rock-rose (Helianthella castanea) and other plants whose range and habitat requirements might include portions of the park. Policies The District staff will continue past efforts to determine the range and habitat requirements of the jeopardized plants which can and do live in ACRP and will modify their management practices as is appropriate to encourage and protect them. C. WILDLIFE 1. Mammals Objectives These are; to provide habitat for indigenous mammals, to remove untagged domestic dogs and feral domestic cats when their presence conflicts with the previous objective or conflicts with existing recreational uses and to provide suitable population management in case the population of any mammal species declines significantly or rises to levels which result in damage to the park I s natural resources or conflicts with park uses. Policies The District will pursue vegetation management policies which encourage indigenous vegetation (see above) and will carry out appropriate wildlife habitat enhancement projects which have been scientifically demonstrated to be effective. The District staff will trap and remove untagged domestic dogs and feral domestic cats when their presence conflicts with native wildlife or existing recreational uses. Only live traps will be used for this purpose. Only District personnel who have been properly licensed to trap under the State Fish and Game Code will carry out such trapping. Each of the park supervisors will assure that at least one licensed person is available to carry out the trapping in the area he or she supervises. Trapped domestic animals will be surrendered to Alameda County Animal Control Officers. Only when there is an immediate life-threatening circumstance as described 77 above or when a particular problem animal cannot be lured to a trap, will feral domestic animals be dispatched (killed) on-site. Only sworn officers or other District employees who may in the future be so authorized will be called upon to dispatch feral domestic animals on-site. The District will retain the services of an individual qualified in wildlife management to evaluate the population levels of wildlife species in the District (including ACRP) • and to recommend appropriate management practices in cases where the population appears to have declined to levels approaching extirpation or which appears to have risen to levels which result in damage to natural resources or which conflict with park uses. Rationale The policy to remove feral mammals from the park is recommended because their presence conflicts with the objectives of accommodating existing recreational activities and of encouraging native fish and wildlife. These conflicts may occur when they act to spread disease to park users or to native wildlife. This may also occur when the feeding an.d other activities of the feral domestic animals act to reduce the SUitability of the park for native animals. The policy to trap and remove untagged domestic dogs and feral domestic cats is recommended because of the proximity of ACRP to areas of urban development. It may be fairly argued that a policy of dispatching (killing) these animals on-site is both more cost-effective and more humane than trapping and removal. However, responding to the potential adverse reaction of the urban public would require a significant amount of District staff time, thereby reducing the cost-effectiveness of this alternative. The policy retains the option of dispatching especially troublesome animals on-site. The use of sworn officers or other District personnel who may in the future be so authorized, assures that any attempt to dispatch feral mammals in the park Y]ill not result in violations of the laws protecting dogs which have been properly tagged under State law. 2. Birds Objectives to provide habitat for indigenous birds, to remove feral domestic ducks and geese when this presence conflicts with the provisions of habitat for indigenous birds or conflicts with existing recreational uses, to protect an important local breeding area for great blue herons and to provide suitable population management in case the population of any bird species declines significantly or rises to levels which result in damage to the park I s natural resources or conflicts with park uses. 78 Policies The District will pursue vegetation management policies which encourage indigenous vegetation (see above) and will carry out appropriate wildlife habitat enhancement proj ects which have been scientifically demonstrated to be effective. The District will continue to restrict park user access to the great blue heron rookery near Lake Chabot. The District staff will trap and remove feral domestic ducks and geese when their presence conflicts with native wildlife or existing recreational uses. Only live traps or nets will be used for this purpose. Only District personnel who have been properly licensed to trap under the State Fish and Game Code will carry out such trapping. The Chabot Marina supervisor will assure that at least one licensed person is available to carry out the trapping in that unit. Trapped animals will be surrendered to Alameda County Animal Control Officers. Only when there is an immediate life-threatening circumstance or when a particular problem animal cannot be trapped, will feral domestic animals be dispatched on-site. Only sworn officers or other District employees who may in the future be so authorized, will be called upon to dispatch feral domestic animals on-site. The District will retain the services of an individual qualified in wildlife management as indicated under mammals (above). Rationale The policy to remove feral domestic birds from the park is recommended because their presence conflicts with the obj ectives of accommodating existing recreational activities and of encouraging native fish and wildlife. These conflicts may occur when feral domestic birds act to spread disease to park users or to native wildlife. They may also occur when the feeding and other activities of the feral domestic birds act to reduce the suitability of the park for native animals. 3. Other Wildlife Objectives These are; to provide habitat for indigenous reptiles. amphibians, insects and invertebrates and to provide suitable population management in case the population of any species rises to levels which result in damage to the park's natural resources or conflicts with park uses. 79 Policies The District will pursue vegetation management policies which encourage indigenous vegetation (see above) and will carry out appropriate wildlife habitat enhancement proj ects which have been scientifically demonstrated to be effective. The District will retain the services of an individual qualified in wildlife management as indicated under mammals (above). 4. Fish Objective to provide for both a warm water and cold water sport fishery in Lake Chabot. Policy The District will continue to pursue a program of fish habitat improvement and fish stocking which will provide a sport fishery for both warm water and cold water fish on a cost-effective basis. This program will be designed and supervised by the District's Water Management Specialist. 5. Jeopardized Animals Objective to manage the plants and animals in ACRP in a manner which will maintain any existing populations of the Alameda striped racer snake (Masticophis lateralis euryxanthus) and any other jeopardized animal whose range and habitat requirements might include portions of the park. Policy The District staff will continue past efforts to determine the range and habitat requirements of the jeopardized animals which can and do live in ACRP and will modify their management practices as is appropriate to encourage and protect them. D. Water Objectives These are; to assure a high quality of surface water, to assure a high quality of potable water. 80 to provide appropriate fire protection and to reduce the damage to improvements from local flooding along Grass Valley and San Leandro Creeks. Policies The District will pursue erosion control policies to preserve water quality (see below). The District will construct and maintain a domestic water supply system which will provide water for domestic uses in campgrounds and picnic areas and will provide adequate flows for fire protection in portions of ACRP which have been developed with structures. The District will not construct new facilities which could be significantly damaged by flooding within the flood plains of Grass Valley and San Leandro Creeks. The District will design and construct a water channel for the tributary stream which crosses Bort Meadow; this channel will be capable of containing the runoff from a lO-year storm and will be revegetated. using indigenous vegetation. The District will encourage the operators of the Willow Park Public Golf Course to provide formal water channels to carry the waters of tributary streams which now flow across the golf course turf into San Leandro Creek. The District will continue to prohibit equestrian activities on trails which are entirely aligned along creeks or the shoreline of Lake Chabot (i.e•• the Buckeye Trail. the Bird Trail. the Westshore Trail. and the Eastshore Trail). The District will continue to prohibit equestrian activities during the rainy season on trails which are aligned along creeks for a significant portion of their length (i.e.• the Cascade Trail and the Columbine Trail). E. Soil Objectives These are; to minimize erosion in the park. Policies The District will construct roadside fences. as necessary. to exclude illegal access to ACRP by four-wheel-drive off-road vehicles. The District will continue training of its staff in erosion control maintenance practices so that these become an integral part of road and trail maintenance. as called for in the EBRPD Grading manual. 81 The District will close and rehabilitate the Motorcycle Hill area of ACRP to reduce erosion. Siltation basins will be constructed as part of the rehabilitation work. Check-dams and water-bars will be constructed to control erosion on those trails which are closed; these trails will then be revegetated. The District will incorporate erosion control plans as part of any capital improvement project which involves grading or other activities which expose the soil and as a part of its timber harvest plan. The District will design and construct the structures necessary to stablize and reestablish a bottom elevation along Grass Valley Creek sufficient to prevent the bank undercutting and headward erosion which is occuring on the reach of the creek north of Stonebridge • (This action will be taken in cooperation with the City of Oakland. Alameda County. the East Bay Municipal Utility District and the U. S. Soil Conservation Service. For example, the construction of energy dissipators. siltation ponds and gabions will be considered.) Rationale The policy to close and rehabilitate Motorcycle Hill is recommended as a method to reduce the amount of erosion occurring there. The policy to take the steps necessary to stablize Grass Valley Creek is recommended because the present rate of bank failure is sufficient to threaten existing improvements near the creek including those in the Bart Meadow area. Conditions which contribute to this circumstance include the increased amount and speed of runoff coroming from residential and street development in the portions of the watershed which are in the City of Oakland. plus similar effects from Redwood Road and from the Motorcycle Hill area. F. Air Objectives These are; to operate ACRP in a manner ~vhich will avoid violations of air quality standards. Policies The District will conduct prescribed burning operations in accordance with the regulations of the State and Regional Air Quality Management Districts. 82 TABLE OF CONTENTS PAGE V.

SUMMARY The proj ect includes a Land Use-Development Plan (LOOP) and a Natural Resources Management Plan (NRMP). The LUDP includes expansion of existing camping facilities on Las Cumbres. Lost Ridge. Hawk Ridge and at Bart Meadow. It also includes the closure and rehabilitation of Motorcycle Hill. the expansion of facilities at the Marksmanship Range. the expansion of the Equestrian Center and the establishment of picnic areas along Skyline Ridge. The NRMP includes the institution of a fuel reduction program in the brushland and eucalyptus forest areas using prescribed fires. It includes the reintroduction of grazing in the Grass Valley area to preserve grassland. the institution of an erosion control program along the upper reaches of Grass Valley Creek, and the conversion of certain eucalyptus groves to indigenous vegetation, using a timber harvest program. The LUDP and NRMP were developed to avoid and/or mitigate for adverse environmental impacts. The EIR outlines a variety of mitigation measures for erosion control, water quality maintenance and traffic safety which have been incorporated into the project. No alternative was identified which would have a substantially reduced adverse impact upon the human environment. 85 B. BID-PHYSICAL ENVIRONMENT I. Geology, Soils and Seismicity Setting The terrain of ACRP ranges from gentle to rugged. Elevations range from 235 feet at Lake Chabot to about 1200 feet at Vulture I s View. Lake Chabot is formed by a liS-foot-high earth-fill dam. The dam is 1300 feet thick at its base, 50 feet thick at its crest, and rising 120 feet above the streambed. The earthfill \>las washed from the surrounding hillsides using hydraulic mining methods, and compacted by a method called "puddling", in which horses were driven back and forth across the fill, compacting it with their hooves. The bedrock of the park consists mainly of sandstone, shale and conglomerate rocks, deposited during the Cretaceous period (Robinson, 19S6, Radbruch, 1969). Originally classified as a single geologic unit (the Chico formation), these rocks are now divided into three units (see Lindenmeyer, 1982, Fig. 4); the name "Chico" formation is applied only where the units have not been studied in detail and differentiated (Perkins, 1974). The erosion-resistant Oakland conglomerate and Redwood Canyon sandstone form the ridges of the park, with the more erodable Shepherd Canyon shales underlying Grass Valley. The Cretaceous sediments terminate abruptly against East Chabot Fault. On the west side of Lake Chabot, the extensive bedrock faulting results in a complex mixture of rock types, including serpentine, rhyolite, shale and conglomerate. Small areas of recent alluvium, now left as terraces, are located on Skyline, Hawk, Lost and Las Cumbres Ridges. On Chabot Ridge, there is a small area of Pinehurst Shale. Younger alluvial fan deposits are mapped in Grass Valley and along San Leandro Creek above Lake Chabot (ReIley, Lajoie & Burke, 1972). The nearest active bedrock fault is the Hayward Fault located about one mile west of ACRP; this fault is capable of producing a major. damaging earthquake. Soil types in the park are primarily loams. These are thin upland soils of the Gaviota, Los Gatos, Los Osos and Millsholm series, developed under fores t and grassland conditions. All have a low shrinklswell capacity, low or moderate erosion hazard, and present few engineering difficulties (Soil Conservation Service, 1981). Grass Valley contains a deep alluvial soil of the Danville series. The flood plain of San Leandro Creek contains rich, deep alluvial loam of the Yolo series (ibid.). At the Lake Chabot Marina and entrance, there is a small area of clay soils from the Altamont Series (ibid.). This is the only heavy clay soil within the Park. Existing soil erosion problems range from moderate to severe; they are primarily associated with human activities. including residential development, road and trail development, and the use of the Motorcycle Hill area. There are also a number of soil failures, slides, and slumps in various localities within ACRP. The upper reaches of Grass Valley Creek (from Stonebridge to Bort Meadow) are actively eroding as 86 evidenced by bank undercutting, headward erosion scarps and deeply incised channel profiles. These problems contribute to silt deposition in Grass Valley Creek, San Leandro Creek and Lake Chabot. Impact The LUDP indicates areas for additional development which are located in the relatively level portions of the park. These additional developments would consist primarily of picnic facilities and associated meadows, access roads and parking areas. This type of development requires moderate grading volumes on slopes less than 10 percent. Additionally, grading would occur to reconstruct the trails on Motorcycle Hill, to modify the Marksmanship Range, to develop livestock water sources, and to construct about 7 miles of new trails and trail extensions. This type of development requires moderate to substantial grading volumes on slopes greater than 20 percent. All grading would be balanced on-site. A total of about 65 acres of the site would be affected by grading after the ultimate completion of the LUDP. Significant increases in erosion will occur on all graded sites for the first two rainy seasons following grading, regardless of revegetation efforts. If the silt from the graded areas is not contained in siltation structures, it will contribute to the siltation problems in the receiving waters (Le., the upper San Leandro Reservoir and Lake Chabot). In the event of a large, damaging earthquake, ACRP will be subject to potentially significant damage and simultaneously will be sought as a refuge by several hundred nearby residents. The earthquake damage which may occur could include landslides blocking or damaging roads and trails, rYpture of water and sewer lines, loss of electrical power. downed electrical transmission lines. and possible secondary fires. As a secondary consequence of the loss of power, the District's sewage treatment plant and sewage lift stations serving the Family Campground will become inoperative and probably will require extensive maintenance to return to operation. The possible rupture of sewer lines may result in sewage reaching Lake Chabot. It is not anticipated that either the Upper San Leandro Dam or the dam at Lake Chabot will fail as a direct result of seismic shaking or seiche. Both dams have been improved in accordance with the recommendations of the best scientific evaluation available. Further, the dam which forms Lake Chabot has a history of surviving the last great earthquake which occurred on the nearby portions of the San Andreas Fault in 1906. The EBRPD has adopted an Emergency Operations Plan. This plan provides an organization table and outlines the general missions which the EBRPD will be expected to carry out in accordance with local, State and Federal disaster planning. Specific plans to accommodate disaster refugees in ACRP have not yet been formulated. Most such refugees are likely to arrive at Skyline Ridge, Chabot Marina and at the Willow Park Public Golf Course. 87 Mitigation Proposed as Part of the Project The District will review the establishment and maintenance of existing and planned roads and trails within ACRP with erosion control as a primary consideration. The District will construct and maintain roadside fences. as necessary, to exclude illegal access to ACRP by four-wheel-drive off-road vehicles. The District will continue training of its staff in erosion control maintenance practices so that these become an integral part of road and trail maintenance, as called for in the District I s Grading Manual. The District will close and rehabilitate the Motorcycle Hill area of ACRP to reduce erosion and to eliminate trespassing into the Upper San Leandro Reservoir watershed. Check-dams, water-bars. and siltation basins will be constructed to control erosion as part of the rehabilitation. The District will incorporate erosion control plans as part of any capital improvement project which involves grading or other activities which expose the soil. and as a part of its timber harvest plans. The District will take the steps necessary to correct and prevent bank undercutting and heaclward erosion caused by human activity along Grass Valley Creek from Stonebridge to Bart Meadow. The expansion of the Marksmanship Range facilities includes a .program of erosion control and the construction of a siltation basin. Identified by this Report The institution of erosion controls in the westerly lane of Skyline Blvd. adjacent to ACRP would reduce the silt coming from that road into the park. This measure must be instituted by the City of Oakland. The improvement of the roadside drainage structures along the portions of Redwood Road which border ACRP will reduce the silt coming from that road into the park. This measure must be instituted by Alameda County. 88 Prepare detailed plans specifically for ACRP to provide (open) shelter, sanitation. medical care, food and water for earthquake disaster refugees. This measure is being carried out as part of a District-wide program and is not specifically part of the planning for ACRP. 2. Hydrology and Water Quality Setting ACRP lies entirely within the San Leandro Creek watershed. The park contributes to two major tributary streams - Grass Valley Creek and Redwood Creek. San Leandro Creek is a public water supply watershed. The runoff from most of ACRP flows directly into Lake Chabot which currently serves as an emergency water supply for portions of the EBMUD service area. The local watershed (including only that below Upper San Leandro Reservoir) is 12 square-miles. Lake Chabot is a 315-acre reservoir. one of the five terminal reservoirs of EBMUD's water distribution system. The lake has an estimated capacity of 4.1 billion gallons of water. Body-contact water-sports are not permitted. due to the emergency water supply status of the lake. The lake waters are thermally stratified from about April to November (Britton, Ferreira & Averett. 1974). The warmer surface layer varies, but is about 10 feet deep and is well oxygenated (ibid.). The colder lower layers (below 30 feet) have reduced oxygen levels which approach zero at the greater depths (ibid.). During the winter months. the waters of the lake mix and the temperature and oxygen content of the water is the same from the surface to the bottom (ibid.). The lake waters have a high amount of total dissolved solids (230 ppm) (ibid.). The water level of the lake fluctuates about 10 feet each year; the high level occurs in the early spring and the low level in the late summer (Vecchiarelli, 1967). Other water supplies in ACRP include several springs along Redwood Road and in other draws and ravines. A small drainage west of Bort Meadow contains a spring. The lower end of Grass Valley Creek is a perennial stream. Well capacity is unknown but has been mapped as marginal with yields likely to be less than five gallons per minute (Webster. 1972). There are two livestock ponds in the Cow Hollow area of the park. The western and southern sides of ACRP adjoin urban areas, which generate storm runoff containing pollutants typical of urban areas. Storm waters from approximately 12.5 miles of paved road (including Skyline Blvd .• Redwood Road and Lake Chabot Road). are also discharged into the park. However, most of the runoff from the Grass Valley Creek watershed comes from the vegetated slopes within that watershed. Runoff from the San Leandro Creek watershed comes from Redwood Regional Park. ACRP and from the watershed lands of EBMUD; all of these lands are undeveloped, open space lands. The quality of this runoff is affected by silt. The maj or sources of silt include the unpaved portions of Skyline Blvd., unpaved service roads and Motorcycle Hill. Other sources include road cuts along paved roads. hiking trails. riding trails, the marksmanship range, landslides and other slope failures. 89 The runoff characteristics of the San Leandro Creek watershed are influenced by the presence of the Upper San Leandro Reservoir. This reservoir is one of the terminal storage facilities in EBMUD's system; it receives water from EBMUD' s water supplies in the Sierra Nevada Mountains. The Upper San Leandro Reservoir is drawn-down during the summer months and is refilled primarily with water from the Sierra Nevada Mountains during the winter months. Thus, local runoff from storms which occur early in the winter months are retained in the Upper San Leandro Reservoir; however, towards the end of the winter and in the spring, this reservoir is full and local runoff is passed through the spillway and flows down San Leandro Creek to Lake Chabot. Under these circumstances. local flooding may occur along the portion of the creek which flows through the Willow Park Public Golf Course. This is exacerbated by the lack of sufficient capacity of the bridge which carries the main access road to the clubhouse area of the golf course. Floodwaters carry silt which is deposited in the streambed. on the golf course and in Lake Chabot; this silt also acts to exacerbate flooding problems. An additional consideration in this watershed is the long-standing plan for EBMUD to construct an additional reservoir between the Upper San Leandro Reservoir and Lake Chabot. This plan would involve part of the area now used for the Willow Park Public Golf Course. Impact There are four areas of ACRP where existing and planned development occur in the flood plains of Grass Valley and San Leandro Creeks. The first area is Bart Meadow; local flooding occurs from Grass Valley Creek and from a small tributary creek which crosses the meadow from west to east. Flooding has occurred from Grass Valley Creek when sto~1ll waters have deposited debris, blocking the culvert under the primary access road. Flooding has occurred from the tributary creek when flood flows have exceeded the capacity of the small channel which was placed by EBRPD in an attempt to route the creek around the edge of the meadow. Existing facilities at Bort Meadow include picnic tables and a series of toilets which drain into two underground concrete vaults. Past flooding has not resulted in flood waters entering these vaults, as the openings to them were above the high water mark. There are no new structures planned at Bort Meadow which would be adversely affected by flooding. The second area is Corral Hollow; local flooding occurs from Grass Valley Creek and from a small tributary creek which crosses the area from east to west. Grass Valley Creek floods in this area because the low gradient of the valley floor means that the creek channel is not deep enough to contain flood waters; this type of flooding is normal and occurs with almost every significant storm. The small tributary stream in this area lacks a well-defined creek channel. Flood waters form a shallow pond behind the road berm of the access road and cause significant erosion when the berm breaches at its weakest point. This berm is reconstructed every year as an incidental part of road maintenance. Planned development at Corral Hollow includes minimal facilities to accommodate hiking and camping which will not be adversely affected by flood waters. 90 The third area is Marina draw; local flooding occurs when heavy runoff combines ~1ith high lake levels. The only existing structure in this area is a small wooden footbridge which is expendable. No new structures are planned in the portion of the Marina which is subject to flooding. The fourth area is the Willow Park Public Golf Course; local flooding occurs when late season storms cause runoff which raises the Upper San Leandro Reservoir to the elevation of its spillway, as described above. Existing development in the flood plain includes a golf course. driving range and clubhouse. No additional development is planned by EBRPD in this area. Any plans for development of a new water supply reservoir (by EBMUD) would be subject to separate environmental impact evaluation. All existing and planned recreation which contributes to erosion will adversely affect the quality of the runoff water and of the waters of Lake Chabot. Equestrian activity adjacent to or within a creek channel also can adversely affect water quality, both as a result of the physical disturbance of the creekbed and as a result of animal wastes entering the runoff waters. In the event of a major earthquake. it is possible that the sanitary sewer lines serving the Chabot Family Campground, the Marina and the Willow Park Public Golf Course will rupture, and sewage will reach Lake Chabot. Overuse. misuse. and accidental spills of fertilizers and pest control chemicals also could result in pollution or Lake Chabot. especially if this occurs during the winter rainy period, or during a flood. The primary area within ACRP where these materials are used is the Willow Park Public Golf Course. Mitigation Proposed as Part of the Project The District will pursue erosion control policies to preserve water quality (see Section 1 above). The District will not construct new facilities which could be significantly damaged by flooding within the flood plains of Grass Valley and San Leandro Creeks. The District will provide a water channel and replace the road crossing for the tributary stream which crosses Bort Meadow. This channel will be designed to accommodate a storm which has the probability of occurring once every 10 years, and revegetated, using indigenous plants. The District will continue to prohibit equestrian activities on trails which are entirely aligned along creeks or the shoreline of Lake Chabot (i.e •• the Buckeye Trail, the Bird Trail. the Westshore Trail, and the Eastshore Trail). 91 The District will prohibit equestrian activities during the rainy season on trails which are aligned along creeks for a significant portion of their length (i.e., the Cascade Trail and the Columbine Trail) . Identified by this Report Reconstruct the Willow Park Public Golf Course access road where it crosses San Leandro Creek so that it does not act to restrict the flow of floodwaters and thereby promote siltation on the golf course. This measure must be instituted by the golf course operator. Provide formal water channels across the Willow Park Public Golf Course to carry the waters of tributary streams which now flow across the golf course turf into San Leandro Creek. This measure must be instituted by the golf course operator. Provide a storage area for fertilizers and pesticides at the Willow Park Public Golf Course. This area should be located above the flood plain; it should have an impermeable surface and should be surrounded by a spill containment berm. This measure must be instituted by the golf course operator. 3. Air Quality Setting ACRP has a Mediterranean climate; cool. wet winters and warm, dry summers. The summer heat is moderated by the influence of coastal fog. When warm temperatures persist in the inland valleys of the State for several days. a local low pressure area is created. This draws the cool coastal fog inland to the ACRP area. where its persistence from late evening until late morning acts to limit the high temperature of the day. In the winter, the daily high temperatures are in the mid-50' s (degrees Fahrenheit), while evening lows are in the mid-30's; frost is rare. In the summer. the daily high temperatures are in the mid-70's, while evening lows are in the low 50's. Winds come predominantly from the west, except during winter storms. Typical summer wind patterns are calm in the morning hours. with breezes of up to 15 to 20 miles per hour occurring in the evenings. and calm returning at night. During the winter, huge cyclonic storms come off the Pacific Ocean. These are generally preceded by one or more days of southerly winds caused by the counterclockwise circulation of the storms. Precipitation occurs almost exclusively as rainfall brought by the winter storms; snow and hail are rare. About 90 percent of this precipitation falls between the months of November and March. Total precipitation amounts to between 22 and 24 inches per year (Rantz. 1971). Some of the plants in ACRP are able to supplement this rainfall by condensing moisture out of the summer fog and/or by absorbing it directly from the air. Air pollution may tend to make local rainfall 92 and fog acidic; however, there is no data from within the park to document this. Lake Chabot measures slightly alkaline (PH 8.1), indicating that any such effects have not yet affected the lake. There have been no air quality measurements taken from within ACRP. The park is assumed to experience violations of State and Federal Air Quality Standards for oxidants because this is a Region-wide problem which has been measured in areas both to the east and west. Oxidants are largely a product of photo-chemical reactions between air pollutants in the atmosphere. Within the last decade. violations of oxidant standards have declined in frequency because of reduced emissions of those pollutants which enter into the reaction (sulphur and nitrogen oxides. and particulates). fortunate weather patterns, and fuel conservation. Violations occur primarily during calm weather periods when cold air is trapped in the valleys of the region with a layer of warmer air above. Under these conditions. all emissions into the air are trapped and contained until wind or storm activity mixes the air layers and disburses the pollutants. There are two "fixed" sources of air pollution within ACRP; cattle and eucalyptus trees. Both emit hydrocarbons; the cattle emit methane and eucalyptus trees emit a volatile oil. Mobile sources within ACRP include automobiles traveling on roads and streets adjacent to the park. and the motorcycles on Hotorcycle Hill. These mobile sources emit oxides of nitrogen. particulates. carbon monoxide and hydrocarbons. It is not likely that any violatic:ms of standards result from emissions occurring in the park because of the low number of vehicles involved. and because there are no standards for methane hydrocarbons. Impacts The NRMP will institute three changes in the park which may affect air quality. First. additional livestock grazing would occur to preserve grassland areas in the park. Second, eucalyptus trees would be removed to provide fuel breaks and to preserve the integrity of the native mixed evergreen forest. The first change would act to increase hydrocarbon emissions occurring in the park while the second would reduce them. The net effects of these two opposite changes is unknown. The third change is to institute a program of prescribed burning as a vegetation management tool. Prescribed fires will emit primarily oxides of nitrogen, carbon dioxide and particulates. There may also be emissions of volatile oils from eucalyptus, poison oak and other plants as they are burned. The oxides of nitrogen and particulate emissions have the potential to contribute to region-wide oxident violations, and may result in local exceedance of standards for these individual pollutants in and around the burn site. The emissions of volatile oils could present a health risk to those individuals who are allergic to them and who are exposed to the smoke from a prescribed fire. For these reasons. the setting of prescribed fires is regulated by State and Regional Air Quality Management Districts. Such fires are restricted to days when the predicted weather pattern provides good mixing of the upper and lower atmospheres, to reduce the likelihood of violations of air quality standards. 93 Mitigation Proposed as Part of the Project The District will conduct prescribed burning operations in accordance with the regulations of the State and Regional Air Quality Management Districts. 4. Ecology Human influence has had a significant effect on the vegetation of ACRP, due to the introduction of large numbers of European grazing mammals (for 200 years), the extirpation of the tule elk and the extinction of the California grizzly bear, the subsequent removal of grazing mammals from the park (except in Cow Hollow), the suppression of wildfires, the logging of redwood trees, the planting and logging of eucalyptus trees, and the creation of Lake Chabot. Despite these changes, ACRP retains the character of a natural-area parkland with a variety of plant associations described and discussed below. Grassland occupies about 1,200 acres of the park. The grassland consists primarily of introduced annual species, such as wild oats. barleys and bromes. Some areas also contain stands of native grasses. particularly on the rockier sites. Needlegrass, meadow barley and creeping wildrye are the most common natives. Native wildflowers in the park are diverse and abundant; species include the California poppy. wyethias, brodiaeas. and mariposa lilies. A great variety of herbs and grasses have been identified from ACRP; these are listed in Appendix A of the Resource Analysis (Lindenmeyer. 1982). After grazing mammals were removed (in the mid-1950's). coyote brush began actively to invade the grasslands. Extensive plantations of eucalyptus trees were placed in the grassland portions of the park, starting in about 1910. Brushland occupies about 1.200 acres of the park. In northeast-facing slopes and canyon areas, the brushland consists of such species as coffeeberry, thimbleberry, ninebark, rose. ocean spray, osoberry, toyon, currant, blueblossom and blue elderberry. In the drier, south and west-facing sites. the brushland includes stands of coyote brush, sagebrush. and monkeyflower. In certain east-facing slopes, the brushland includes chamise. manzanita, toyon. blueblossom. black sage and mountain mahogany. In the Grass Valley area. the brushland consists of almost pure stands of coyote brush. A species list is found in Appendix A of the Resource Analysis (ibid.). The brushland is subject, and adapted to, the periodic occurrence of wildfires. Such fires consume the standing dead branches of the brushy plants, releasing their nutrients to the soil, and creating soil conditions conducive to the germination of the seeds of the brushland plants. In the past 50 to 100 years. humans have actively suppressed wildfires. The result has been an accumulation of standing, dead 94 branches which (in some older stands of brushlands) would result in wildfires of a much greater intensity than would occur under a more regular periodic burning regime. The mixed-broadleaf forest occupies about 1,200 acres of the park. The trees in this forest are coast live oak, bay, and madrone, with maple and buckeye present in smaller numbers. Under the trees there is a rich shrub and herb layer, including poison oak, blackberry, hazelnut, and numerous other shrubs. Common herbs include Solomon's seal, fairy bells, woodland star, alum root, angelica and several species of ferns, including sword fern and wood fern. In the east-facing draws at the north end of Chabot Ridge, there are about 50 acres where this community includes the coast redwood tree. A species list is found in Appendix A of the Resource Analysis (ibid.). This association has not experienced a great degree of disturbance from human activities. with the exception of the logging operations. which harvested virtually all the redwood trees in the park during the 1850s. Eucalyptus groves occupy about 500 acres of the park. This community consists of blue gum and red gum eucalyptus trees, with an understory of shrubs and native evergreen trees which is similar to that found in the mixed-evergreen forest. These trees were planted around 1910. In December 1972, the East Bay area experienced a prolonged freeze. an infrequent recurring phenomenon in the area. The low temperatures caused extensive damage to many tropical and subtropical plants in the area, including eucalyptus. The eucalyptus trees produce a large volume of litter on the forest floor. including leaves. branches and long shreds of bark. This material is not rapidly decomposed because of the dry climate, and because the non-native eucalyptus plant material is not as susceptible to native decomposers as the native plant material. The result has been accumulations of plant litter of up to 40 tons per acre (Fenwick, 1980). Under such circumstances. a wildfire would be severe and uncontrollable (ibid.) • Riparian Woodland occupies the streambank areas of Grass Valley Creek. It includes arroyo, yellow and red willow, white alder. black cottonwood and an understory of shrubs, including poison oak, blackberry, ninebark. creek dogwood, twinberry and blue elderberry. A maj or willow grove occurs at the lower end of Willow Park Public Golf Course, near Lake Chabot. Riparian trees also occur along San Leandro Creek within the golf course area. including willow. white alder, black cottonwood and sycamore. Aquatic and emergent vegetation occurs more or less regularly around the shoreline of Lake Chabot. Cattails are the most common emergent plants, along with bulrushes and sedges. Several aquatic species of knotweed (Polygonum) occur in slightly deeper water. Algae, especially blue-green algae occur throughout the lake in some numbers. Two aquatic plants, Potamogeton and Myriophyllum. are of particular concern. as they have infested two areas of Lake Chabot, including the marina area where 95 it can restrict boat passage. Recent dredging operations have eliminated the shallow water conditions conducive to these plants in the marina area. Exotic vegetation plantings include cultivars around old homesites and the conifer tree plantings done by the EBRPD. Four homesites occurred in what is now the park; these sites include fruit, locust, walnut, and acacia trees. Several huge eucalyptus occur at Bort Meadow. Over the years, several stands of Monterey pine and other conifers have been planted around Lake Chabot and in Grass Valley by EBRPD personnel, as called for in the 1965 LUDP. These have generally been small groves or scattered individuals. In 1974, two redwood groves were planted in former eucalyptus areas, one at the northern end of the fuelbreak area at the western boundary of the park, and a second in Grass Valley extending northward about ~ mile from the Stonebridge area. In 1982 another grove of redwood trees was planted in the Bort Meadow area. There are four jeopardized plants which occur or may occur in Chabot Park. The first is western leatherwood (Dirca occidentalis) which occurs in Deer Canyon, in Bird Canyon, and may occur on the western sides of Grass Valley and Grass Canyon. The western leatherwood is found on moist, rocky hillsides below 1,500 feet in Sonoma, Marin, San Mateo, Contra Costa and Alameda Counties. It is rare, but present in sufficient numbers, that the potential for extinction is low; its populations are increasing or stable in numbers; however, it is restricted entirely to the San Francisco Bay Region. The second plant is the Diablo rock-rose (Helianthella castanea) which may occur on grassy hillsides along Chabot Ridge. The Diablo rock rose is found on grassy hillsides between 500 and 4,000 feet in Alameda, Contra Costa, San Francisco and possibly San Mateo Counties. It is restricted to a few populations, several of which may be threatened by development; its populations are increasing or stable in numbers; however, it is restricted entirely to the San Francisco Bay Region. The third is the fare-well-to-spring (Clarkia rubicunda rubicunda) which occurs on the hillside below the equestrian center and alongside Redwood Road. The fare-well-to-spring is found on grassy hillsides including serpentine soils in Alameda, Contra Costa, Monterey, San Francisco, San Mateo, Santa Clara and Santa Cruz Counties. It is rare, but present in sufficient numbers, that the potential for extinction is low; however, it is restricted to the San Francisco and Monterey Bay Regions. The fourth is the Oakland star tulip (Calochortus umbellatus) which occurs on Chabot Ridge above Bort Meadow. The Oakland star tulip is found in grassy openings on dry, wooded hillsides, often on serpentine soils, in Marin, Alameda, Contra Costa and Santa Clara Counties. It is rare. but present in sufficient numbers, that the potential for extinction is low; however. it is restricted to the San Francisco Bay Region. These plants have been listed by the California Native Plant Society in its Inventory £!.. Rare and Endangered Vascular Plants (Smith, et al., 1980). These plants have not yet received official protection under either State or Federal law. The diversity and the extensive intermixing of vegetative communities provides a productive wildlife habitat. Water is reliably available at Lake Chabot, as well as along portions of Grass Valley and San Leandro 96 Creeks, (other water sources are more seasonal). The eastern slope of the north end of Chabot Ridge contains numerous springs. The mixed-broadleaf forest and eucalyptus groves support the greatest number of animals. because of the many food sources (native plants under the eucalyptus and virtually all plants in the mixed-evergreen forest) and good cover. The brushland contains some species unique to it, and the grasslands are important as habitat for rodents and their predators, such as hawks and owls. The mammals found in the park include raccoon, long-tailed weasel, California ground squirrel, pocket gopher, deer mouse, black-tailed jackrabbit and black-tailed deer. Both domestic dogs and cats are found roaming free in the park. Domestic horses are kept in the District I s equestrian center and are often brought to the park from nearby privately-operated stables or by trailer. A more complete species list is found in Appendix B of the Resource Analysis (Lindenmeyer, 1982). Domestic cats appear to have become feral throughout much of the park. There appears to be a number of these animals living in the vicinity of the Chabot Family Campground on Las Cumbres Ridge where they apparently obtain food from the campers. These animals can inflict serious injury with their teeth and claws, if handled by park users. They are also capable of transmitting diseases such as rabies and plague to humans, and feline distemper to the pets of park users and park neighbors. The domestic dogs which have been observed roaming in the park appear to be pets from the adjacent neighborhoods. Although these animals may not have gone feral, they harrass and occasionally may kill wildlife in the park. No hunting for mammals is permitted in the park. The birds include a variety of raptors such as red-tailed hawk, sparrow hawk, and golden eagle. There are several bird species associated with aquatic habitats, including canvasback duck. mallard duck, American coot, osprey, great blue heron and great egret. Among the songbirds in the park are the horned lark, scrub jay, chestnut-backed chickadee. bushtit. northern mockingbird, American robin, song sparrow, western meadowlark, and American goldfinch. Many migratory birds also use the park, including the ducks, barn swallow. cedar waxwing, solitary vireo. MacGillivray I s warbler and purple finch. At Lake Chabot there are a number of domestic ducks and geese which are present on Oak Island and in Marina Cove. A more complete species list is found in Appendix B of the Resource Analysis (ibid.). The domestic ducks and geese found on Lake Chabot appear to obtain much of their food from park users in the Marina area. These animals are causing significant damage to the styrofoam floats which support the docks at the marina. Domestic geese are capable of inflicting painful wounds with their beaks and claws. if handled by park users. Both domestic ducks and geese are capable of harboring avian cholera. which could be transmitted to wild migratory waterfowl using Lake Chabot. The eucalyptus trees located on a peninsula into the Bass Cove portion of Lake Chabot offer a breeding area for colonies of great blue herons. These large and attractive birds are desirable and interesting to 97 observe. Public access to the heron rookery area has been restricted, to assure continued breeding success. No bird hunting is permitted in the park. The reptiles and amphibians include species such as the western fence lizard, northern alligator lizard, gopher snake, striped racer snake, Pacific rattlesnake, Pacific treefrog, red-legged frog, and western pond turtle. A more complete species list is found in Appendix B of the Resource Analysis (ibid.). The Pacific rattlesnake is a poisonous animal, however, there have been no incidents of park users suffering from their bites within recent years. Although frog catching is permissible under State fishing regulations, the District's night curfew regulations substantially limit it in ACRP. The insects and invertebrates of the park are diverse and abundant. There has been no systematic attempt to surveyor identify them. There is a potential for certain common insects to conflict with park users. Ants, yellow jackets and domestic bees can be annoying if present in campground and picnic areas. Most such areas in ACRP are in areas with eucalyptus trees which do not offer the hollow tree habitat favored by domestic bees. The tree-hole nesting mosquito is found in the mixed-evergreen forests of ACRP. This animal is capable of transmitting a parasite of dogs, called heartworm. There is no effective pest control method for the tree-hole nesting mosquito (Dr. D. Sanders, 1983, personal communication). The aquatic animals of the park are found primarily in Lake Chabot; however. there are some species in Grass Valley and San Leandro Creeks. Among the planktonic animals are species of the rotifers, copepods and cladocerans. Among the gamefish present are rainbow trout, catfish, largemouth bass, bluegill, black crappie, and carp. Notable among these. are landlocked native steelhead, which have not hybredized with the hatchery trout planted in the lake. These unusual fish live in the Upper San Leandro Reservoir and spawn in Redwood and other local creeks. During periods of high rainfall, some individuals are believed to be washed over the spillway and down to Lake Chabot. Among the non-game fish are golden shiner, goldfish, and Mississippi silverside. A more complete species list is found in Appendix B of the Resource Analysis (ibid.). The fishery in Lake Chabot is a managed one. Between 80,000 and 100,000 catchable-sized trout and catfish are planted in the lake each year. The planting is done at two or three-week intervals throughout the year. Marina Bay has been dredged to a bottom configuration which is suitable for fish spawning, and fishing is prohibited there. Additionally, there are 70 "fish hotel" structures sunk in various localities in the lake. These structures are made of rubber tires; they provide both spawning and escape habitat for fish. The result is a popular fishing area. There probably i.s one jeopardized animal in the park this is the Alameda striped racer snake (Masticophis lateralis euryxanthus). This animal is protected as "rare" under the California Endangered Species Act. This 98 snake has been noted most often in brushland areas which have rocky and grassy openings; it is found only in Alameda and Contra Costa Counties. The only study of this animal, which included diet items, indicated that western fence lizards were a primary food (Hammerson, 1979). There are several hundred acres within ACRP which may offer suitable habitat for this animal. There is no information about whether this habitat is occupied by the Alameda striped racer. Impact The NRMP will institute a number of changes in vegetation and wildlife management practices. These are intended to achieve stated objectives which are generally to improve the quality of the park's environment. The following discussion will center on those aspects of the proposed practices which could go wrong. The most significant potential for such an occurrence would be if one of the fires set to reduce excess fuel escaped Hcontrolll. This is most likely to occur when there has been an unpredicted change in weather conditions after the fire has been set. A IIworst case" occurrence would be if a prescribed fire crossed the fuel breaks established around its periphery and spread into an area of Skyline Ridge which had a high accumulation of fuel. and which had urban development on the ridgecrest above the fire. Under these circumstances, an lIescapedll prescribed fire might cause significant damage to the vegetation of the park~ loss of property, personal injury and/or death in the urban area above the fire. The circumstances of the "escapell of a prescribed fire may be beyond control (or mitigation). However, once a prescribed burning program is established, the areas adjacent to any particular prescribed fire site probably would have been burned within recent years and would not have a high accumulation of fuel to burn. Thes, the greatest danger of escape occurs in the first few years of burning when the fuel accumulations of many years of past fire suppression have not yet been removed. Another potential for adverse impacts would occur if the livestock which graze in the park were mismanaged. The result could be overgrazing, loss of wetland vegetation, erosion, and \cJater pollution. This could adversely affect the grassland herbs which occur in the grazed area and could contribute to conditions which put certain of those plants in jeopardy of extinction. The wildlife dependent upon the grazed area and the fish in the streams and lakes downhill would be adversely affected. The result would be a reduced value to a parkland serving the residents of the southwestern portion of Alameda County. Similar adverse impacts would occur if the timber harvest activity were mismanaged. Lake Chabot is a large body of water; it is not likely that major spills of sewage, fertilizers or pest control chemicals will completely destroy the fishery there. Such a spill, however. may render the surviving fish unfit for human consumption for some period of time. 99 The planned new trails, road extensions and new parking areas would result in the loss of about 65 acres of vegetation, most of which is grassland. A significant number of acres of the park will be landscaped in association with new development in the recreation units. This will amount to about 30 acres; however. the exact acreage cannot be estimated without specific capital improvement plans for each of the recreation units. This land is primarily grassland. No existing or planned development occurs or would occur in portions of ACRP known to support populations of jeopardized plants or animals. The introduction of well-managed grazing into grassland portions of the park which support or may support populations of the Diablo rock-rose, the fare-well-to-spring and/or the Oakland star tulip, is likely to improve habitat conditions for these plants by removing the annual grasses and preventing a build-up of thatch on the ground. The use of prescribed fires for vegetation management is not likely to adversely affect those three grassland plants or the Alameda striped racer snake; the grassland plants are adapted to the periodic occurrence of wildfires, the snake is active during the day when such fires would be set and would therefore may be able to flee from the flames or seek refuge in rodent burrows. Thus, while individuals may be killed during prescribed fires, there are likely to be sufficient survivors that the species will persist in the area. The use of prescribed fires could adversely affect the persistence of western leatherwood in the park; however, this plant normally occurs in moist areas as part of the understory of the mixed-broadleaf forest. Prescribed fires would not be set in this community because it does not typically have the high accumulations of dry fuels which present a fire bazardand because periodic fires are not necessary to maintain the health of this plant association. Mitigation Proposed as Part of the Project The District will establish and maintain a system of fuel and fire breaks dividing the park into management units. It will use prescribed fires to reduce the hazards of wildfires in the brushland and eucalyptus forest and to assure the long-term preservation and enhancement of the brushland association. (This will be accomplished under the direct supervision of the District Fire Chief or a qualified employee appointed by the Chief). The District staff will continue past efforts to determine the range and habitat requirements of the jeopardized plants and animals which can and do live in ACRP and will modify their management practices as is appropriate to encourage and protect them. The District staff will trap and remove untagged domestic dogs, domestic cats, domestic ducks and domestic geese when their presence conflicts with native wildlife or recreational uses. Only when 100 there is an immediate life-threatening circumstance or when a particular problem animal cannot be lured to a trap, will untagged feral domestic animals be dispatched (killed) on-site. (The District will form team of staff members qualified in wildlife and resource management issues to implement this policy.) The District will continue to restrict park user access to the great blue heron rookery near Lake Chabot. The District will continue to pursue a program of fishery habitat improvement and fish stocking which will provide a sport fishery for both warm water and cold water fish on a cost-effective basis. (This program is designed and supervised by the District's Water Management Specialist.) The grazing activity in the park will be carried out as part of the District's grazing program which is supervised directly by a Revenue Analyst who sets limits on the amount of grazing and assures that overgrazing is controlled. The timber harvest activity in the park will be designed and supervised by the District's Land Management Specialist, in accordance with the provisions of a timber harvest plan appropriate to characteristics of the site and of the tree species. 5. Noise Setting The ridge along the easterly side of ACRP varies from 600 to 1,000 feet in elevation; this effectively shields much of the park from the noise of the adjacent urban areas. The low levels of traffic on the roads adjacent to the park do not represent a significant source of noise. In general, the noise levels in ACRP may be characterized as those of rural areas which typically range from 40 to 50 decibels on a 24-hour noise scale called the Community Noise Equivalent Levels (CNEL). There are three activities in ACRP which produce significant increases in noise when they occur. These activities are aircraft overflights, off-road motorcycle use, and the operation of the Marksmanship Range. Overflights of large jet-powered aircraft generally occur between 8 and 15 thousand feet above the park. Overflights of small piston-engine aircraft and helicopters generally occur between one and five thousand feet above the park. None of this activity is frequent enough or loud enough to interfere with normal conversations between people within 10 feet of each other, although it is audible throughout the park area. The EBRPD police helicopters frequently fly over the park as described above; however, occasionally they operate at lower altitudes when participating in law enforcement or rescue activities or when landing at Public Safety Headquarters. These helicopters are based at Hayward 101 Airport. and landings at headquarters occur only when a. specific purpose requires it. The landing pad is located in a topographic depression. The nearest structures are the EBRPD police headquarters bUilding and the EBRPD South County Service Yard maintenance building. The nearest residential structures are about 1.000 feet easterly and southerly of the landing pad. Exterior noise levels in the nearest residential neighborhoods are loud enough to interfere with normal conversations for a period of two to three minutes during takeoff and landing operations on the helicopter pad (Wilson, Ihrig & Assoc.. 1976). However, such operations are so infrequent that they do not contribute significantly to the exceedance of EPA recoIDnended noise criterion for outdoor activities (ibid.). Off-road motorcycle use is limited to a single 66-acre portion of the park. It occurs primarily during the late afternoon on weekdays and on weekends during daylight hours. This activity is also seasonal, and diminishes during the winter months, due to wet weather and trail conditions. This activity occurs in a. ridgetop locality which supports grassy and shrubby vegetation. The motorcycles include both 2-stroke and 4-stroke engines which vary in age and alterations performed by their owners. Thus, noise levels produced by motorcycle engines vary considerably from vehicle to vehicle. There are also various motorcycle sports practiced in this area, ranging from slow speed "trials competition" to higher speed trail riding. These various methods of operating motorcycles produce great variation in engine noise. Although no measurements have been taken, it is likely that motorcycle engine noise measured at 50 feet would vary from 70 to 95 decibles, depending upon the factors outlined above. ~~en several motorcycles are using the park, they are audible over the entire Grass Valley and Upper San Leandro Reservoir area. This noise is not loud enough to interfere with a normal conversation between people within 10 feet of each other anywhere outside the immediate Motorcycle Hill area itself. Activity at the Marksmanship Range is limited to a single ravine area which has heavily wooded hills both in front and behind the firing lines. The range is open from 9 a.m. to 5:30 p.m., Wednesday through Sunday. Most of the activity occurs in the late afternoon on weekdays and during the entire operating period on weekends. The range is open to competition events held by organized private groups, law enforcement agencies, and the Chabot Gun Club (which operates the range). The firearms used at the range are limited to single-action and semi-automatic small arms. No rapid-fire is permitted. Large-bore rifles and large-bore handguns produce a sharp report resulting both from the escape of explosive gases and from the sonic "boom" of the projectiles which travel at speeds in excess of 1,100 feet per second (the speed of sound). Blackpowder rifles, blackpowder handguns, shotguns, many small-bore rifles and many handguns do not propel projectiles faster than 1,100 feet per second and, therefore, produce a less pronounced report. The simultaneous firearms discharge typical of competition shooting can result in a combined report more pronounced than any produced by an individual weapon. The noise produced by the 102 discharge of an individual weapon which propels a projectile faster than 1,100 feet per second is sufficient to present a risk of hearing loss to individuals within 25 feet of the weapon. Hearing protection devices are available at the range master's office and are universally worn by range users. Noise levels from the Marksmanship Range were measured during a weekend when maximum activity was occurring (Wilson. Ihrig & Assoc.. 1983). This included a high-power rifle competition, a shotgun competition. a law- enforcement/combat handgun competition. and a variety of individual shooters using over 50 of the firing positions on those rifle and pistol ranges which are open to the public. Measurements were taken at the group picnic areas on Lost Ridge (about 2.000 to 3,000 feet from the range), at Las Cumbres Ridge (about 3,000 feet from the range). at the intersection of Skyline Blvd. and Grass Valley Road (about 6.000 feet from the range), and on Moran St. in Oakland (about 8,000 feet from the range) . The single-event peak noise levels are indicated in Table 2. These measured noise levels are not sufficient to interfere with a normal conversation between people within 10 feet of each other. Further, the noise levels measured in the nearest residential areas (in Oakland) would not contribute significantly to exceeding the EPA recommended noise criterion for outdoor activities. Table 2 Daytime Single-Event Noise Levels at Use Areas Near the Chabot Marksmanship Range Proposed Background Existing 500-Meter Location Noise Range Noise Range Noise Lost Ridge 42-47 dBA 51-58 dBA 60-68 dBA (Group Picnic) Las Cumbres Ridge 40-45 dBA 51-57 dBA 57-65 dBA (Family Campground) Skyline/Grass Valley 42-47 dBA 56-61 dBA 60-67 dBA (future picnic area) Monan Street 42-47 dBA 53-59 dBA 60-66 dBA (Oakland residential area) Source: Wilson. Ihrig & Assoc., 1983 103 Impact The LUDP does not include a significant alteration of the flight patterns, or landing facilities for the EBRPD police helicopter. Thus, no change in aircraft noise would occur. The LUDP includes the closure and rehabilitation of the Motorcycle Hill area. The closure of this area will significantly decrease the volume of noise generated by eliminating motorcycle use. The LUDP includes the expansion of facilities at the Marksmanship Range. The Chabot Gun Club has proposed a variety of new facilities, including a new IOO/200-meter small-bore range, two new pistol ranges. four new trap ranges. and a new SOO-meter!600-yard range (see Fig. IS). The firing line for the proposed new SOO-meter range would be outside the physical confines of the ravine in which the remainder of the facilities are contained. Noise measurements were made of test firings by five marksmen standing at this proposed new SOO-meter firing line. The test firing simulated the simultaneous firing typical of competition events. The result of these measurements are shown in Table 2; they indicate a significant (S-6 decibel) increase in noise at all points measured. Further. these increased noise levels would contribute significantly towards the exceedance of EPA recommended noise criterion for outdoor activities in all the measured localities. Most individuals will probably obj ect to the noise levels which would result from the proposed new SOO-meter range. if it were constructed without any noise abatement features. Individual reactions to lesser noise levels, even those which are not loud enough to interrupt a normal conversation, will vary in accordance with a variety of factors, including their underlying approval of the noise-producing activity, their expectations of a recreation experience, and their perception of personal control over their exposure to the noise. Mitigation Proposed as Part of the Project See the mitigation measure regarding the closure and rehabilitation of the Motorcycle Hill area in Section 1 (above). This would reduce noise by eliminating motorcycle activity. The District will post the Motorcycle Hill area to eliminate its use by motorcycles. The universal use of hearing protection devices at the Marksmanship Range will continue. 104 The construction of new facilities at the Marksmanship Range will include the noise abatement features identified in the consultant's technical report (Wilson, Ihrig & Assoc, 1984) and summarized below: a. SOO-meter/600-yard high-power rifle range o partial enclosure structure around the firing line o landscaped berm along the southerly and westerly sides of the firing area o landscaped berm along the westerly side of the impact area b. lOO/200-meter small-bore rifle range o partial enclosure structure around the firing line o landscaped berm along the westerly side of the entire length of the range c. New 25-yard and 7-yard pistol ranges o grading to reduce the elevation of the ranges o partial enclosure structure around the firing lines o landscaped berm along the southerly side of the ranges d. New trap ranges o grading to reduce the elevation of the ranges o partial enclosure structure around the firing positions o landscaped berm along the southerly side of the ranges The implementation of these measures will effectively prevent increases above background noise levels as a result of the proposed new facilities. Id·entified by This Report The District will reach an agreement with the Chabot Gun Club, upon a schedule for the retrofitting of the existing facilities with noise abatement features identified in the consultant's technical report (Wilson, Ihrig & Assoc .• 1984) and summarized below. a. 200-yard high-power rifle range o improve the partial enclosure structure around the firing line o landscaped berm along the westerly side of the firing area 105 b. lOO/50-yard rifle range o partial enclosure structure around the firing line o landscaped berm along the southerly side of the firing line c. 50-yard public pistol range o partial enclosure of the firing line d. 50-yard reservable pistol ranges o improve the partial enclosures around the firing lines e. Trap ranges o partial enclosures around the existing firing positions The implementation of these measures will effectively reduce the existing noise levels from the Marksmanship Range. No approval of expansion of range facilities will be granted until noise levels from existing facilities have been reduced to the level of background noise as measured at nearby residential areas and camping facilities (see Table 2). 6. Visual and Aesthetic Setting Urban development is visible from the northern end of Grass Valley, at scattered locations along Skyline Ridge, and from the southern boundary of the park adjacent to Castro Valley. On the whole, however, ACRP presents a visual impression of remoteness. Lake Chabot, Willow Park Public Golf Course and Grass Valley area users are presented with a variety of self-contained views across meadows, streams and lake waters. The visual attention of the ridge area users is often focused to the east across 70 square-miles of watershed and range lands with Mt. Diablo forming a prominent distant horizon feature. Ridgetop views to the west include panoramas of San Francisco Bay. the San Francisco Peninsula beyond, and the extensive urban development around the Bay. The park itself is visible primarily from the public roads on its periphery. The City of Oakland has designated the portions of Skyline Blvd. adjacent to ACRP as a possible future scenic route. Views of ACRP from Skyline Blvd. are limited by the depressed topography of the roadbed in many areas; however. there are three or four localities where panoramic views are available across Grass Valley to Chabot Ridge and beyond. The visual impression from these viewpoints are of an extensive 106 undeveloped area covered with a mosaic of grass, shrub and forest vegetation. Alameda County has designated both Redwood Road and Lake Chabot Road as scenic routes. Views of ACRP from Lake Chabot Road are limited by extensive groves of eucalyptus trees along much of its length; however, there are many places where Lake Chabot is visible with forested hills beyond the lake. Views of ACRP from Redwood Road are many and varied along the nine miles which it borders or passes through the park. At the northerly end of the road, views are of a steep wooded slope, along the central portion of the road there are a variety of views along the length of Grass Valley, along the southerly portions of the road views are of a brushy wooded canyon with views of a golf course along the creek bottom. Impact The new development called for in the LUDP would not be highly visible from outside the park. New picnic facilities and associated parking and landscaped areas along Skyline Ridge would be visible from Skyline Blvd. New picnic facilities at the Marina would be visible from Lake Chabot Blvd. New trail development in the Motorcycle Hill area would be visible from Redwood Road and Pinehurst Road. Neither of these roads, serves more than 1,000 vehicles per day. Grading to construct additional facilities at the Marksmanship Range will ~nvolve about 15 acres. Most of this grading will be visible only to users of the range. However. the fill required to construct the firing line and associated noise abatement berm for the SaO-meter! 600-yard range will be visible to users of the nearby portions of the Brandon Trail and from the Brandon Staging area. This fill will be about 40 feet in height. Figure 14A shows artist's renditions of this fill as seen from the staging area (upper) and the trail area (lower). This fill will decrease in visibility because its landscaping will grow to act as a visual screen. Mitigation Proposed as Part of the Project The cut and fill slopes will be landscaped with indigenous vegetation at the time of construction. 107 C. SOCIO-ECONOMIC ENVIRONMENT 1. Land Use and Planning Setting ACRP is bordered on the west primarily by developed private residential subdivisions and three public holdings; the Lake Chabot Municipal Golf Course, Knowland State Park, and Chabot "City" Park. The first two are operated by the City of Oakland. The Chabot "City" Park is owned by EBMUD and leased to the City of San Leandro which operates it on a reservation only basis. On the north. ACRP is bordered by Redwood Regional Park. On the east, the park adjoins watershed lands of EBMUD. On the south, the park adjoins the developed residential area of Castro Valley. ACRP has been developed with a variety of facilities for recreational uses. These are described in detail in Chapter II, Background, Chapter III, Land Use-Development Plan discussion (above) and in the ACRP Resource Analysis (Lindenmeyer. 1982, pp. 9-12). There are also large areas of the park which are maintained as natural areas. The General Plans of Alameda County. the City of Oakland and the City of San Leandro all show various open space categories for ACRP. (Alameda County, 1978, the City of San Leandro, 1975, the City of Oakland, undated.) The Open Space and Conservation Element of the Alameda County General Plan (Alameda County, 1973) includes principles to provide park, recreation and nature areas within the open space adjacent to each community, to keep ridgelines and steep slopes as open space, to limit development in open space areas by prohibiting high-density commercial recreation areas. and to encourage low-intensity commercial recreation in selected open space areas. Lake Chabot and adj acent property (totalling about 1.500 acres) are owned by the East Bay Municipal Utility District and maintained and operated by EBRPD. The basis of the lease agreement is the EBMUD policy document. "Land Use Master Plan of the EBMUD" (1970). In the EBMUD Land Use Master Plan, the Lake Chabot area is classified primarily as a Recreation Management Area and further divided into the following categories: "Developed Recreation" areas for comparatively intensive use levels. primarily for water-oriented activities. including boat docks and other marina facilities. parking areas. picnic and campsites, conference centers, riding stables, golf courses and other uses. "Undeveloped Recreation" areas, low-intensity use areas ~lhere public access is permitted. but developments limited to basic sanitation and other minimum facilities. 108 "Public Service" areas, sites suitable for schools. hospitals, Utility District facilities or other institutional uses in the public interest. (In this category near ACRP is the 143-acre filtration plant site near Chabot Dam.) The 1980 Master Plan of the EBRPD identifies ACRP as the southernmost regional park serving the west metropolitan area of the District. The Master Plan also identifies planning and management guidelines for both natural areas and recreation units within a regional park. Within natural areas, development should be limited to basic but not elaborate facilities necessary for camping, hiking, horseback riding. nature study and other outdoor activities; forest and land management techniques such as livestock grazing, tree cutting, prescribed fires and planting using indigenous plants may also be used. Within recreation units a broad range of facilities may be developed, including campgrounds, picnic areas. snack stands. outdoor education facilities. equestrian facilities. beaches, bathhouses, archery fields, turfed meadows and other regional outdoor recreational facilities. In addition to the Master Plan, the EBRPD is developing a parkland zone plan for each of its maj or land holdings. This zoning identifies recreation units. natural areas, educational use areas and special protection areas. The appropriate uses within the recreation units and the natural areas are described in the Master Plan. The educational use areas are identified by the District I s Educational Use Committee as areas where scientific studies of the physical and natural resources may be appropriate. The special protection units are identified by the District staff and include areas where rare or endangered species live, unique habitats, important wildlife breeding areas and historic resources requiring special protection. Impacts There are two areas adjacent to the park with potential for major land use change. The first is to the southwest of Lake Chabot, where there are two large tracts of privately owned land. These are in an unincorporated area planned for agricultural uses by Alameda County. However, the possibility of development of these properties could change the character of the viewshed and result in increased storm runoff and siltation into Lake Chabot. The second is the portions of ACRP which are owned by EBMUD and developed as a golf course. This area has been planned for a possible new reservoir since the late 1800s; however. the plans have not yet been finished. The proposed (new) LOOP would result in the development of ACRP by expansion of existing uses and the development of new low-intensity recreation facilities (former plans for a conference center. a swimming complex, new park headquarters, bicycle rental concession and extensive afforestation are not included). The proposed LUDP is consistent with the General Plans of Alameda County. the City of Oakland, the City of San Leandro, the East Bay Municipal Utility District. and the East Bay Regional Park District. 109 Mitigation None required. 2. Traffic and Circulation Setting ACRP is bordered on part of it.s western boundary by Skyline Blvd., on the southwest by Lake Chabot Road, and on the east by Redwood Road. Along Redwood Road, there are four parking areas (called staging areas): Macdonald Gate - 20 cars, Bort Meadow Gate (formerly Big Trees and before that San Leandro Gate) - 20 cars, Marciel Gate - 40 cars and trailers, and Ten Hills Gate - 15 cars and trailers. Additionally, there is an access road and parking lot for about 305 vehicles associated with the clubhouse facilities of the Willow Park Public Golf Course. From Lake Chabot there is a large (200-car) staging area serving the picnic and marina facilities. Along Skyline Blvd. there are two gates: Grass Valley Gate - 20 cars, Chabot Equestrian Center - 30 to 40 cars. Park Ridge Drive is a local access point with on-street parking only. Two other local access points with on-street parking only, are located on Estudillo Avenue at "Chabot City Park" and at Lake Chabot Road on the McGregor-George Trail. There is one EBRPD road open to the public within ACRP; this is the 3.5-mile-long road from Marciel Gate (along Redwood Road) to the Marksmanship Range and the Chabot Family Campground. The public roads which serve ACRP are lightly traveled; their alignment and traffic volumes are shown in Figure 20. A description of each road is prOVided below. Redwood Road borders or passes through ACRP for a distance of about nine miles. It is a paved, two-lane, curving mountain road, with reduced sight-distances and narrow shoulders for much of its length. The portion of Redwood Road which is southerly of the Willow Park Public Golf Course serves about 1,000 vehicles per day; the portion north of the golf course serves about 500 vehicles per day (data based on weekday traffic counts taken in the late 1970s and early 1980s). The road adjacent to the park has an accident rate (based on 1982 accidents) of about 1.3 accidents per 100,000 miles traveled; most accidents involve a single vehicle either running off the road or overturning. The locations of these accidents do not suggest that they are associated with the entrances to ACRP. Lake Chabot Road borders ACRP for a distance of about 1.7 miles. The 0.4-mile segment southerly of the Fairmont Drive intersection is a paved, four-lane, divided roadway with a parking lane, curbs and sidewalks on each side. The portion of this road northerly of Fairmont Drive is a paved, two-lane, curving mountain road with reduced sight-distances and narrow shoulders for portions of its length. The portion southerly of :£i'airmont Drive serves about 10,000 vehicles per day; the portion northerly of Fairmont Drive serves about 3,500 vehicles 110 Fig. 20 REDwcoo TO BERKELEY h,,~ RE6/0NAL TRAFFIC PARI<. 1} o 500 lOCO 1111111111111 .J111111111111 -scALE IN FEET .AWDT 2,000 2,30 AWDT 2,000 2,300 AWDT 1,000 1,30 AWDT' 500 2,10 AWDT 1,900 3,50 _-----TO CASTRO VAL.L.EY EXISTING "." - -1- ......

The portion of this road northerly of Fairmont Drive has an accident rate (based on 1982 accidents) of about 0.2 accidents per 100.000 miles traveled; these are primarily single-vehicle accidents. The locations of these accidents do not suggest that they are associated with the entrance to the Lake Chabot Marina area. Skyline Boulevard borders ACRP for a distance of about three miles. The northerly 0.25 mile segment of this road (just south of Hansom Drive) is a paved. four-lane. divided road, with a parking lane and curbs on each side. The southerly portion is a paved, two-lane road, with an unpaved shoulder along its eastern side only (this portion has been graded as a four-lane. divided road; however, the westerly lanes are unpaved and little used). The portion of Skyline Boulevard northerly of Keller Drive serves about 2.000 vehicles per day, while the segment southerly of Keller Drive serves about 1,000 vehicles per day (this data is based on weekday traffic counts taken in the late 1970s). The portion. of Skyline Blvd. northerly of Keller Drive has an accident rate (based on 1974-1979 accidents) of about 0.2 accidents per 100.000 miles traveled, while the segment southerly of Keller Drive has an accident rate (based on 1974-1979 accidents) of about 0.5 accidents per 100,000 miles traveled. Over one-half of the accidents on the portion of Skyline Blvd. south of Keller Drive occurred at the intersection of Skyline Blvd. and Grass Valley Road. At that point, both Skyline Blvd. and Grass Valley Road end, and all traffic must make a sharp right-angle turn through the intersection. The approaches to this intersection recently have been marked with "slow" signs and with massed "Bott Dots" in the travel lanes. Additionally, a sign has been posted at the end of Skyline Blvd. indicating the required turn with an arrow; this sign has two alternately-flashing warning lights. The accidents which have occurred at this point appear to be primarily single-vehicle accidents where vehicles run off the road and strike a fixed object. There was, at one time, a staging area (parking lot) for family picnic facilities in ACRP located at the southerly leg of the Skyline Blvd. /Grass Valley Road intersection. Although an unpaved level area remains, this area is now only a gated service entrance to the park. Thus, it appears that the incidence of accidents at this intersection is more related to the configuration of the road, than to any effects of traffic entering or leaving ACRP. Marciel Road is a paved. two-lane. curving mountain road. with reduced sight-distances and narrow shoulders for much of its length. It is about 3.5 miles long, and is entirely within ACRP. No traffic count is available for this road; however, it is estimated that it serves about 150 vehicles per day (based on recent use of the campgrounds, picnic areas and the Marksmanship Range to which it provides access). This 112 road has an estimated accident rate of about 2.1 accidents per 100,000 miles traveled. Many of the accidents involve a single vehicle, where a vehicle runs off the road; however, there are a significant number of two-vehicle side-swipe accidents. In most accidents, excessive speed appears to have been a factor, and citations were issued. About one-half of these accidents occurred along a series of curVes located about one mile southerly of Marciel Gate. At this location, there are reduced sight-distances along the road, narrow shoulders, a deer crossing, and a panoramic view of the southern portion of the East Bay hills. There are approximately 37.5 miles of service roads within ACRP used for maintenance, fire protection, and as hiking and equestrian trails. All are unpaved except for the 4.5 mile-long Lakeside and Lakeview Trails at Lake Chabot, which are designated bicycle trails, and the 1.5 mile-long road serving Lost Ridge and Hawk Ridge Group Camps. In addition to the service roads, there are several miles of hiking and equestrian trails unsuitable for vehicles. These are found in Grass Canyon and the northeast shore of Lake Chabot. ACRP is not currently accessible by public transportation along Redwood Road. During the summer, AC Transit Route 91 provides bus service to the Lake Chabot Marina as an extension of its regular route on Lake Chabot Blvd. The AC Transit Route 46A stops at the intersection of Keller Avenue and Surrey Lane in Oakland, about two blocks from the Equestrian Center. The AC Transit Route 56A ends about four blocks from Grass Valley Gate. The AC Transit route V-I provides express commuter service between Skyline Blvd. and San Francisco, with morning and evening runs. Impacts Estimates of the traffic impacts from increased traffic volumes associated with the project were based on the following assumptions: 1. all existing planned facilities would attract the maximum number of individuals for which they are designed, 2. vehicle occupancy of 2.1 persons per vehicle, 3. no coordination between user groups regarding arrival or departure times, 4. all recreation areas are assumed to be fully occupied on the same day and are added to the existing weekday traffic volumes on City and County roads, even though existing volumes already reflect trips by users of existing park facilities, 5. peak-hour traffic volume is 12 percent of the daily total and 6. traffic is evenly split with respect to direction at each park entrance, except at the Willow Park Public Golf Course and the Ten Hills staging area where all traffic is assumed to be southbound. 113 Under these "worst-case" assumptions. the peak hour traffic volumes for each of the road segments serving ACRP were estimated and are shown on Table 3. Daily volumes are also shown in Figure 20. None of these traffic volume increases will result in a significant reduction in the existing high levels of service. No traffic congestion would occur; however, minor queuing may take place at Marciel Gate during the evening peak hour as vehicles wait to enter Redwood Road. The traffic volumes assumed for this analysis represent simultaneous full use of all park facilities on a weekday; such an occurrence is extremely unlikely. TABLE 3 Estimated Traffic Volumes Existing plus Existing Project AWDT Peak AWDT Peak Redwood Road - two lanes 1,100 130 2,700 300 (E/O Skyline) Redwood Road - two lanes 1,900 230 4,200 500 (N/O Ten Hills) Skyline Blvd. - two lanes 1,000 120 1,200 140 (S/O Keller) Lake Chabot Road - four 10,000 1,200 11,000 1,300 lanes (N/O Brookdale) Marciel Road - two lanes 150 18 1,000 130 (S/O Marciel Gate) AWDT Traffic volume in a 24-hour weekday period. Peak = Traffic volume during the evening-peak, one-hour period Traffic oriented to and from ACRP would travel on road segments which have an accident history as described above. In 1982, Redwood Road was resurfaced, and some minor changes in alignment were made. In 1983. landslides damaged Redwood Road in several localities. There also have been recent improvements made to the Skyline Blvd. /Grass Valley Road intersection. as described above. In 1982. brush was cut back or removed from the road shoulders of Marciel Road, thereby increasing. somewhat, the sight-distances along that road. These changes in road conditions may affect future accident rates. Never-the-Iess. the projected increases in traffic statistically imply an increase in the 114 number of accidents which would occur on the affected roadways. The EBRPD's responsibility with respect to traffic, is primarily associated with the entrances to ACRP from roads operated by other public entities and with the operation of Marciel Road. There is no apparent need to physically modify the entrances to ACRP; however, a number of safety improvements are needed along Marciel Road. Mitigation Proposed as Part of the Project The District will maintain signs notifing drivers they are approaching all the entrances to ACRP use areas. The District will post Marciel Road every mile with both roadside and painted pavement signs indicating the 25-mile per-hour speed limit. The District will post appropriate curve signs with subordinate speed signs along Marciel Road. The District will paint two-way barrier stripes along the centerline with reflective glass beads in the paint the entire length of Marciel Road. The District will post signs warning drivers that they are approaching a deer crossing about one mile south of Marciel Gate on Marciel Road. The District will place a pair of two-way yellow reflective markers every 24 feet along the entire length of the centerline of Marciel Road. 3. Community Services Setting Municipal water is available along much of the park1s west side. Water supplies come from the EBMUD system which relies upon surface water sources in the East Bay hills and in the Sierra Nevada mountains. Separate metered lines serve the Equestrian Center, Bart Meadow, and the southern Chabot Ridge portions of the park. The Chabot Ridge water system includes a 125,OOO-gallon reservoir to supply Chabot Family Campground and another reservoir to supply the Marksmanship Range. Individual lines also serve the Chabot Marina, Public Safety Headquarters/South Corporation Yard, and Willow Park Public Golf Course. Electrical power and telephone service are available at the Marksmanship Range, Chabot Family Campground, Chabot Marina, the service complex and Willow Park Public Golf Course. One major electric transmission line and one smaller electric utility line cross the park. Lines serving District facilities are underground. 115 Bottled gas is provided to facilities at the Marksmanship Range, Chabot Marina and the Willow Park Public Golf Course. A piped supply of natural gas is available at the service complex. Sewage from the Chabot Family Campground is pre-treated in a small "package" treatment plant near the campground and then pumped to a sewage line near Grovenor Road which receives it into the Castro Valley Sanitary District (CVSD) system. There are severe limits to the hydraulic capacity of the EBRPD treatment plant resulting from a progressively decreasing size in the diameter of the sewage collecting lines as flow approaches the plant. Further. there are two hydraulic problems associated with the outfall lines leading from the EBRPD plant to the CVSD sewage plant. The first problem is in the EBRPD line from its treatment plant to the Grovenor Road line. This line is. in fact, a siphon which has a variable flow rate that includes long periods (up to several weeks in the winter) when there is virtually no flow. This leads to the settlement of solids in the bottom of the siphon. These settled solids act to reduce the hydraulic capacity of this line. The second problem is that the Grovenor Road lift station pumps sewage into the same gravity collection line which serves ACRP. When this pump station operates, the gravity line is at or near its capacity. Sewage from the Chabot Marina and Willow Park Public Golf Course is pumped into the CVSD system through separate lines. The Corp Yard/Public Safety complex feeds into CVSD lines by gravity. Other facilities are served by holding tanks or chemical toilets. These are emptied periodically by the District's tanker trucks which transport the waste to the CVSD system. Impacts The majority of ACRP users are also residents of the service area of the EBMUD; thus, their water use within ACRP does not represent an increase in demand for water from EBMUD. However. increased family camping facilities (which primarily serve individuals who do not live within the EB~IDD service area) and increased irrigated turf areas (associated with group picnicking and camping areas) are aspects of the LOOP which represent an increased demand for water supplies. These improvements represent a potential increased demand for water of about 21 acre-feet per year. The LUDP does not include improvements which would require significant increases in the use of energy or which would conflict with the power transmission lines which cross the site. Increases in sewage generated as a result of an expansion of the Chabot Family Campground could amount to flow increases of up to .003 million gallons per day (mgd) on a peak occupancy day. These flows would not be significant with respect to the capacity of the EBRPD or CVSD treatment facilities. Such a flow rate will contribute to exceeding the hydraulic capacity of the lines feeding into and draining away from the existing EBRPD sewage treatment plant. 116 Mitigation Proposed as Part of the Project The District will perform a complete engineering evaluation of its sewage treatment system in consultation with officials of the CVSD and will accomplish the needed improvements as part of the construction program to expand the Chabot Family Campground. 4. Archaeology and History Setting When the first Europeans entered San Francisco Bay in 1769, they found the San Leandro Creek area occupied by a tribelet called the Jalquin. This was apparently a small family group (numbering about 100 individuals) who spoke a dialect known as Bay Miwok (Milliken. 1981). These people were hunters and gatherers; the women gathered acorns, roots. bulbs, seeds and greens, while the men hunted deer, elk, small mammals, migratory waterfowl and fished (Banks, 1982). In 1797, the Mission San Jose was built in the Fremont area. Its records show that between 1801 and 1807, at least 62 Jalquin individuals were brought to the Mission (Milliken, 1981). In 1836. the missions of California were secularized and the surviving Indians were released. A search of the records of previously discovered prehistoric resources revealed only one such site occurs in ACRP (Banks, 1982). This site consists of four groups of bedrock mortars located in the vicinity of the Willow Park Public Golf Course (ibid.). A surface survey of about 500 acres of the park (in areas where development has occurred or may occur) did not uncover any further prehistoric resources (ibid.). Subsequently, staff has noted what may be two bedrock mortars along Chabot Ridge north of Cottontail Canyon. There are no historic buildings remaining in ACRP. Two buildings are shown on old maps in the Bort Meadow area (Banks, 1982). One building is shown on old maps in the vicinity of Corral Camp (ibid.). There may have been four or more other structures in ACRP in the past (ibid.). These may have been located near the MacDonald Gate. near the Brandon/Equestrian Center Trail intersection, at the base of Chabot Ridge by the Grass Valley Trail, and near the Willow Park Public Golf Course (ibid.). These structures were probably associated with residential and agricultural uses of the American homesteaders; they were probably removed when the land was acquired for watershed purposes. There is one significant historic site located near Chabot Dam but outside ACRP. This is an encampment used by the Chinese immigrant laborers who constructed the dam and its associated tunnels. This encampment has been called Yema-po (wild horse ridge) (Miller. 1981). It appears to have been occupied from the time of the initial dam construction (1874) until the turn of the century (ibid.). 117 Impacts The LUDP will not have a direct physical impact upon any identified cultural resource. The policies in the Natural Resources Management Plan would allow non-native plants which do not reproduce to die and not to be replaced. These plants are the only identified remains of the early ranches in the park area. This would not result in the loss of any significant scientific information about these early ranches. Mitigation None needed. 5. Energy Setting Fuel energy is used by park patrol vehicles. by maintenance vehicles and equipment. and by park visitors who travel to and from the park and operate their vehicles within the park. Electrical energy is used to pump water to the park. to remove sewage from the park, and to supply the energy for golf carts and boat motors and maintenance and operations facilities. There is no reliable way to estimate the amounts of energy involved. Impacts The provision of recreation opportunities which are not available in city parks in a location which is close to a major urban area may result in energy savings. This could occur if ACRP users would otherwise have traveled a greater distance to participate in these activities. There is no reliable method of estimating any such savings. The NRMP includes the institution of a timber harvest program in certain of the eucalyptus groves in ACRP. This harvest will result in the use of at least some of the timber products as a source of fuel; there is no reliable method of estimating any such energy production. Mitigation None required. 6. Fiscal Setting There are nine fee or concession activities in ACRP. The equestrian center and the golf course are concessions operated by a private business. The Marksmanship Range is operated by a non-profit private gun club. The EBRPD operates a marina, the campgrounds, the reservable picnic areas, the grazing program and the fishing program. 118 The revenues and estimated maintenance and operation expenses are shown in Table 4. This shows that except for the marina, each of these activities produced more revenue than expenses in 1982. The loss at the Marina is associated with reduced revenues because of construction activity. and is not expected to continue. TABLE 4 1982 Annual Revenues and Estimated Expenses for ACRP Estimated Net Activity Revenue Expenses Revenue (loss)* Grazing $ 1,400.00 $ 140. 00 $ 1. 300. 00 Fishing 36.000.00 24.000.00 12,000.00 Picnicking 260.00 100.00 160.00 Camping 54.000.00 23,000.00 31,000.00 Marina 180,000.00 210.000.00 (30, 000.00) Marksmanship Range 5.000.00 1,400.00 3.600.00 Equestrian Center 5,400.00 3,100.00 2,300.00 Golf Course 29,000.00 18,000.00 11 ,000.00 Net Total $31,000.00 *Rounded to two significant digits. Impacts The NRMP includes the expansion of the grazing program which could result in an increase in revenues. It also includes the institution of a timber harvest program for some of the eucalyptus groves which could result in a new source of revenue. No expansion of the fishing program is planned. The LUDP would provide an increase in facilities for camping and picnicking which could produce an increase in revenues. There probably would be an increase in revenues to the EBRPD from the planned expansion of the Marksmanship Range and equestrian facilities, based upon the increase in land needed and people served; however, the amount of these increases would be subject to negotiation and no specific change can be predicted. No change in golf course facilities is planned. These increases in revenues (to the extent they can be predicted) are shown in Table 5. 119 Table 5 Projected Annual Revenues and Estimated Expenses for ACRP (1983 dollars) Estimated Net Activity Revenue Expenses Revenue (loss)* Grazing $ 5,400.00 $ 540.00 $ 4.900.00 Fishing* 36.000.00 24.000.00 12,000.00 Timbering 36.000.00 6,000.00 30.000.00 Picnicking 5.800.00 2,500.00 3.300.00 Camping 74.000.00 33,000.00 41, 000. 00 Marina 240.000.00 210,000.00 30,000.00 Marksmanship Range** 5,000.00 1,400.00 3,600.00 Equestrian Center** 5.400.00 3,100.00 2,300.00 Golf Course 28,800.00 18,000.00 11.000.00 Net Total $140,000.00 *Rounded to two significant digits. **No change is predicted or any change is problematic and cannot be predicted. Mitigation None needed. 120 D. IMPACT OVERVIEW 1. Unavoidable Adverse Impacts The LUDP would have the following unavoidable adverse impacts. Increases in erosion for the first two years following a project involving grading. Grading in the Motorcycle Hill and Marksmanship Range will contrast visually with surrounding vegetated areas until revegetation and landscaping grows to cover and screen it. Pollution of Lake Chabot with sewage in the event of a large, damaging earthquake. Pollution of Lake Chabot with fertilizers or pesticides in the event of an accidental spill of these materials. Increased methane emissions from increased livestock grazing. Possible escape from control of a prescribed fire set as part of the planned vegetation management policies. All of these are adverse impacts which would occur, to some degree, despite mitigation measures outlined in the DElR. These adverse impacts are the kinds of risks faced by all development in the region. The LUDP is proposed, despite its unavoidable adverse impacts. because the benefits of providing the proposed regional park facilities are judged to outweigh the adverse impacts. 2. Irreversible Environmental Changes Once expanded camping. picnicking, Marksmanship Range, Motorcycle Hill facilities, and service roads are completed, it is unlikely that significant human use of the affected land would ever cease. Thus, they represent an irreversible commitment of land from a "natural" condition to a recreation oriented use. 3. Short-Term Uses Versus Long-Term Productivity The uses included in the LUDP are all long-term uses, The Natural Resources Management Plan is designed to increase the productivity of ACRP as part of the human environment. The LOOP is proposed at this time as part of the EBRPD's regular review and reevaluation of land uses required by the 1980 Master Plan. 4. Growth-Inducing Impacts The institution of wood-product harvest activity in ACRP may result in an increase in regional employment of three to five jobs. These probably would be jobs in the private sector working for contractors to the EBRPD. This does not constitute a significant growth-inducing impact. 121 5. Alternatives a. The No Project Alternatives would not make further capital improvements in ACRP. Existing natural resource management practices would continue unaltered. This alternative would avoid the grading necessary to develop additional recreational facilities and therefore the erosion associated with that grading. However, no actions would be taken to rectify the erosion occurring on Motorcycle Hill and along Grass Valley Creek. The net result would be significantly more erosion than would occur with the project. This would result in potential adverse impacts upon the water quality and managed fishery of Lake Chabot; these would be worse than the impacts of the proj ect. Because there is no existing fuel management plan, this alternative would eliminate the potential for an "escape" of a prescribed fire. However, it would have a significantly higher probability of an uncontrollable wildfire than would occur with the project. Such wildfires would have substantially increased adverse impacts upon vegetation and wildlife than would occur under the fuel reduction practices which are part of the project. This alternative would continue the existing relatively high probability of automobile accidents along Marciel Road; under the project the probability of such accidents would be reduced. This alternative is not recommended because it vlOuld have substantially increased adverse impacts upon the human environment compared to the project (as outlined above). b. The Existing LUDP Alternative includes substantial capital developments within ACRP. These improvements include a Conference Center, a new lake with a beach/swimming complex, a Visitor Center building, a bicycle concession building and about three miles of new two-lane paved public roads. This alternative also would include all of those improvements contained in the project. The construction of the improvements in the existing LUDP would cause substantially more erosion than would occur with the proj ect. This would result in potential adverse impacts upon the water quality and managed fishery of Lake Chabot; these would be worse than the impacts of the project. Because this alternative does not include a fuel management plan there would be no potential of an t'escape" of a prescribed fire. However, it would have a significantly higher probability of an uncontrollable wildfire than would occur with the project. Such wildfires would have substantially increased adverse impacts upon vegetation and wildlife than would occur under the fuel reduction practices which are part of the project. This alternative would substantially increase the probability of automobile accidents along Marciel Road; under the project the probability of such accidents would be reduced. This alternative is not recommended because it would have substantially increased adverse impacts upon the human environment compared to the project (as outlined above). 122 c. The Third Alternative consists of the alternate uses which have been suggested during the planning process and were not part of either the existing LUDP or the recommended project. The rehabilitation and permanent establishment of the Motorcycle Hill area has been advocated by several individuals and one organized user group. This was not included in the project because the Board of Directors directed staff to study its options for providing a motorcycle facility at a more appropriate location. The Chabot Gun Club proposed a program of expansion for the Marksmanship Range which is included in the project. Concerned citizens have proposed either these facilities should be closed. or that no expansion of them will be allowed. This alternative would avoid the potential for adverse impacts associated with the project. (e.g., erosion of graded areas and increased noise). Since mitigation has been included to reduce these potential adverse impacts to acceptable levels, any reduction in adverse impacts associated with this alternative would be problematic. This alternative 'vas not included in the LUDP because it would not provide recreation facilities for which there is a clear and substantial public demand. A concerned citizen has proposed the rerouting of the trail from Chabot "Cityll Park to ACRP. This route is outside the EBRPD' s lease area around the lake. is threatened by a major landslide and could disturb the historically important cultural artifacts of the Chinese worker's camp called Yema-Po. Because of the resource management and cultural implications of the proposed realignment, it was not included in the LUDP. There have been three specific proposals for uses at Marciel Gate. These are: a quarter midget racecar track a commercial concession for an archery range a designated range for survival games while the LUDP designates the area as a special recreation area, no specific use has been shown. The proposal for designation as a survival game range would not require substantial physical changes; thus, no environmental review was required. On January 3, 1984, the EBRPD Board of Directors considered this proposal and rej ected it. The remaining proposals require public works improvements, removal of hazardous vegetation, liability protection and changes to EBRPD ordinances. They also have a variety of potential environmental impacts, which means that they will require a separate feasibility study and environmental impact document before they could be accomplished. The quarter midget racecar track was not included because it is not among the special interest recreation activites specified in the 123 Master Plan, and because the PAC has recommended that it not be allowed as proposed. The commercial archery range was not included because it is inconsistent with adopted plans for regional archery facilities. E. REPORT PREPARATION 1.

All such public input is summarized in II.E, Public Use and Demand. Responses to suggestions on the LUDP and NRMP are summarized in V.D.5., Alternatives. All letters are on file (with report originals) in the Planning and Design Department. 140 APPENDIX D- PUBLIC COMMENTS AND RESPONSES FOR THE FINAL LUDP/EIR A. COMMENTS AND RESPONSES Comments on the Draft LOOP jEIR were received through public hearing testimony and letters. A public hearing was held at the Castro Valley Unified School District Board Room on December 7, 1983. Approximately 80 people attended, representing equestrians, hikers, runners, campers, picnickers, motorcyclists. marksmen. local residents and neighborhood associations. All of the comments are categorized and summarized below. District responses will follow each category. The many comments in support of various aspects of the Plan are appreciated, but are deleted from this discussion unless opposing points of view have been expressed. Also, comments concerning issues other than the LUDP/EIR are not discussed. Natural Resources Management Vegetation: Comment: o Grazing can result in a decrease of park use because of (1) bulls scaring away hikers, (2) excessive cow dung making hiking unpleasant. Response: o The overwhelming majority of visitors to ACRP use facilities such as the Motorcycle Hill, the Equestrian Center, the Marksmanship Range, the Public Golf Course, the Chabot Marina, and the reservable and family campgrounds. No grazing is proposed in these areas. so no conflicts are likely and no substantial reduction in Park use is likely. The reintroduction of grazing in the Grass Valley area will act to halt the process of brush invasion of grasslands, thereby assuring the future possibility of cross-country and trail-side activities to hikers in that area. Conflicts between cattle and hikers are rare events. because of the relatively few numbers of bulls in a typical herd. because EBRPD grazing tenants routinely remove unruly animals from District lands, and because of the relatively short segments of trail passing through the identified grazing area (viz: about three miles of a total of 35 miles of trail) . Wildlife: Comment: o The feral cats don't harm anything. Don't do anything about them. Response: o Feral cats do harm the populations of native small animals and potentially could harm park users. The need for action is outlined in both the Resource Analysis and the Natural Resources Management Plan. 141 Comment: o People enjoy feeding feral cats. Response: o Feeding feral cats compounds the potential for adverse effects on park users (such as possible disease transmission) by increasing their numbers and concentrating them in recreation activity areas. Comment: o One park user, who has hiked for many years. has seen no more than 20 cats. Response: o This species is primarily nocturnal, and would be less likely to be observed by a daytime hiker. Comment: o Ensure that cats of adjacent neighbors are not trapped. Response: o Neighboring pet owners will be able to ensure that their pets are not trapped by keeping them under control. If an uncontrolled animal is trapped in ACRP because of conflicts with park users, the owner will be able to reclaim the animal from the County Animal Shelter. Comment: o Do something to discourage people from dumping unwanted cats in the parks. Response: o This activity is forbidden under Ordinance 38. Comment: o Favor indigenous animals by reducing non-natives. Response: o This is the approach recommended in the Natural Resources Management Plan. LUDP Recreational Facilities Marksmanship Range: Comment: o The Chabot Gun Club presented a proposal for the expansion of the Marksmanship Range (see Fig. 14A & 15) at the December 7, 1983 public hearing. It includes noise abatement measures identified in acoustical studies done by an independent acoustical consultant. These measures would mitigate the adverse noise impacts identified in the LUDP/EIR. Response: o The Land Use-Development Plan is hereby revised in accordance with this latest proposal. 142 Comments in Favor of Expansion of the Marksmanship Range: o Accept the Chabot Gun Club's expansion proposal to meet current public desires and make it a truly Regional facility. Metallic silhouette shooters have to go to Reno. Nevada for a SOD-meter facility. A SOD-meter range would be good for their needs to the year 2000. o The Gun Club proposal is a responsible one. o As many or more people use the marksmanship facilities in a year. than all other park concessions put together. o Hunters need the proposed facility for practice. a We use the park for hiking and equestrian uses and the range does not bother us. o Provide these facilities for local competitive meets. o The proposed ranges could be used for international-style practice. o This area is pleasant, family oriented and should be allowed to expand to meet its potential. o Enlargement of the range is worthwhile to teach shooting skills to pre-military-aged young people as is done in Russia. Comments Against Expansion of the Marksmanship Range: o Guns are totally incompatible with the proper use of a park. There are very few places where a person can go for peace and quiet. Parks are oases of calm and quiet. o It's harder and harder to get away from the city and its impacts. o This use is different from others as it disturbs others. This use displaces other uses and animals from its area. o The Gun Club takes up 98% of the park acoustically and makes it impossible to enjoy the park. o Chabot has bad reputation because of noise and many won't go there. o EXisting weekend range noise bothers nearby homeowners. a The gun range produces constant noise. o Larger facilities would increase the radius of disturbance. o Sound adversely affects the animals. o The existing facilities are adequate and fullfill the reasonable needs of the sportsmen and police officers. o The gun club should abate the current noise level. o See if existing range can be made quieter first. then make it bigger. o Extensive reconfiguration of terrain is required to accommodate the new range. o Don't encroach on Brandon Trail with expansion of the gun range. o Greater numbers of people (unorganized hikers. equestrian. etc.). are disturbed by the gun range than those who use it. o The general public. who are the maj ority of users, are annoyed by the noise. o There are vested interests involved in the gun club acoustical report. o Limit the caliber of the guns used. 143 o Close the gun club one weekend day for the serenity of other park users. Response: o Marksmanship is one of the activities that is regarded as an appropriate parkland use by the Recreation Policy of the EBRPD 1980 Master Plan. The Chabot Marksmanship Range is being expanded in order to modernize it with the longer ranges now used in competitions for high-powered rifles and metallic silhouette shooting. This effort will increase the regional value of the facility and maximize the site's potential for its many users. As a part of the expansion, several mitigation measures will be incorporated to improve existing conditions and alleviate possible negative effects. These include: berms to avoid an increase in sound for the new range sound buffering to reduce the sound from existing ranges silt ponds and other erosion control methods a sewer lift station and line planting of indigenous species for screening An area around the range is affected by the sound generated from the range. The closest areas are Grass Valley and Upper San Leandro Reservoir, although the range can also be heard at Lake Chabot and residential areas to the west and south. With mitigation measures, noise will not increase as a result of new facilities, and will be reduced, as existing facilities are retrofitted. For those park users who find this level of noise unacceptable, other areas of the remaining 50,000 acres of District lands can provide quieter, more undisturbed open space experiences. It is not expected that any new additional ranges will be created by the EBRPD. Grading for the project is extensive, and visual impact for a small area will be great, but native planting can eventually screen it from non-gun range areas (Brandon Staging area). While some animals may have left this area for quieter quarters, deer can regularly be seen feeding on ranges next to ranges in use. Occasionally, these deer enter the line of fire, forcing a temporary cease-fire. The Marksmanship Range is currently closed on Monday and Tuesday. There have not been a sufficient number of requests to consider closing the gun range on a weekend day. The acoustical report was written by an independent consultant under contract to the EBRPD. The EBRPD was reimbursed for the cost of this work by the Chabot Gun Club, as required under the EBRPD Environmental Review Manual. Motorcycle Hill: Connnents in Favor of a Permanent Motorcycle Hill: a Off-road motorcycling is an outdoor sport enjoyed by a large number of District residents. 144 o Improve Motorcycle Hill which has been used and enj oyed for many years by District residents and taxpayers. o Tax fees paid by motorcyclists are available for development of motorcycle areas; other users don't finance their facilities in this way. o A legal place to ride will reduce misuse of other areas. o The District promised residents of Contra Costa County during annexation. that a motorcycle area would be provided. o Clean-up the ruts and make the site safe for riding. o A small area should be located for motocross, perhaps a strip along edge, at the least. o Install directional arrows (signs) on the one-way trails to help prevent head-on collisions. o Utilize local clubs (like East Bay P.I.T.S and Pacific Trail Riders) and professionals as design consultants for improvement of the area. o Provide drinking fountains and toilets. o Some of terms used in report are confusing - please clarify the uses. o Be aware of 1984 deadlines for State funds. Work should be done as soon as possible. o How are restricted activities (hill climb) to be enforced? o Water causes erosion, not trails; so redesign the trail system to stop erosion. o There is not enough parking provided in the Plan. Comments Against a Permanent Motorcycle Hill: o Motorcycles are totally incompatible with the proper use and purpose of a park. There are very few places a person can go for peace and quiet. Parks are an oasis of calm and quiet. o Use is low now, and will dramatically increase when the place is improved, and thus increase the noise. The area should be closed. o Chabot has bad reputation because of noise, and many won't go there. o Motorcycles produce constant noise. o The general public, who are the majority of users, are annoyed by the noise. o Motorcycle Hill noise will disturb those reserving Bort Meadow for camping and picnicking. o The large lake just below the motorcycle hill could conceivably be used for recreation someday. The noise would not make it a peaceful place to boat or fish. Boaters and fishermen want peace and quiet. o This area is on a hill where noise affects a large area; it should be in a valley. o This use is different from others, as it disturbs others. It also displaces other uses and wildlife from its area. o Motorcycle noise disturbs wildlife habitat and trails. o It is common for motorcyclists to remove muffler/spark arrestors. This will be a law enforcement and fire hazard problem. o Area will require disproportionate patrolling and cleanup. o Motorcycle Hill should be closed because of the erosion. o Erosion control will never be adequate while area is being used by motorcycles. o Extensive reconfiguration of terrain required to accommodate this activity. o Place has been better since noise reduced. 145 o Find another place for motorcycles. Response: o A motorcycle area is an activity that may be provided by the East Bay Regional Park District as stated in the Off-Road Vehicular Policy of the EBRPD Master Plan. Alternate sites for this facility have been studied throughout the two-county area. but no suitable area has been found. This site has been used for many years. is liked by motorcyclists. is capable of being rehabilitated to provide several miles of trails. a trials area and motocross practice area on its rolling terrain. Erosion problems can be controlled by rerouting of trails. closure of some localities. and establishing a system of siltation basins. It is within a large metropolitan area where there are a large number of potential users. Fees that these users pay in motorcycle taxes will be utilized to pay for the needed improvements. Noise generated by the motorcycles will increase over current low levels when the site is improved and opened. A maximum of 100 parking spaces including trailers. will be provided. Maximum use capacity is expected to be approximately 220 motorcycles at a time. It will be audible within Grass Valley and Upper San Leandro Reservoir (a potential recreation area). As stated in the EIR. it will not be loud enough to interrupt a normal conversation in the portions of the park outside the Motorcycle Hill area. Reactions to this sound are personal and are related to one I s sensitivity and expectation of an acceptable parkland experience. For those park users who find this level of noise unacceptable. other areas of the remaining 50.000 acres of District lands can provide quieter. more undisturbed open space experiences. No additional motorcycle areas are planned by the Park District. The District will utilize the assistance of local clubs during design development. Safety features (trail alignments. erosion features) and services (parking, chemical toilets) will be maj or elements of the Capital Improvement Plan for Motorcycle Hill. The District is aware of the State I s deadlines for "Green Sticker Money". Mufflers and spark arrestors will be required on all motorcycles. "Widow-maker" (spiked) tires will be prohibited. Public safety problems are not expected to be disproportionate for this facility. Marina: Comments: o The Marina Meadow area (flat area at Nike Base Road and Lake Chabot Road) development should not increase traffic. dust or noise. o Marina Meadow should be a natural area. o Marina Meadow should be developed as a meadow to reduce dust problems. o The trailer camp should be removed from Marina Meadow Plan because it will impact with neighbors. 146 o Previous agreements with local residents guaranteed there would be no development at Marina Meadow. This plan breaks those agreements. The area is not a good site for such a facility. Response: o The trailer or RV camping area is deleted from the Final Plan. This area will be utilized for backup overflow parking and special events. A maximum of 200 parking spaces will be provided. Maximum use is expected to occur fewer than six times per year. An average of 50 or fewer cars is estimated as an average use. The area is expected to reduce parking on nearby residential streets. Dust will be controlled with dust suppresants, irrigated grass or paving treatments. Special events such as boat or art displays, or staging for running events will be arranged through the Lake Chabot crew. It will be visually screened from private residences with earth mounds and vegetation. This area cannot be considered a "natural area" because of its proximity to existing development. It thus has been included in the Lake Chabot Recreation Unit. The area I s flatness and good access to Lake Chabot Road make it a logical area for the limited type of activities described above. A major goal of any design in this area will be to avoid conflicts with adjacent neighbors. Comment: o Use of the island for picnicking could result in possible uncontrolled behavior and other problems. o Picnic areas along the lake are welcome. Response: o The lake is one of the heaviest used areas of the park and is well staffed. The island will be a very popular place to boat to. For these reasons the District does not expect any disproportionate public safety problem on the island. Comment: o Allow private citizens to carry in non-motor driven boats and canoes. (This use could include permit charges, limited areas, limited use of crafts/day and required safety measures.) Response: o Flat land is limited in the Marina area and the priority area around the water I s edge is devoted to recreation rather than parking or boat launching. With this design, access for those carrying boats is through major recreation areas, thus providing a potential conflict, as well as a minimum 700-foot walk. A large outlay of capital funds was required to develop the marina facility and income derived from boat rental is necessary. Enforcement of boat safety would be difficult and could result in liability problems for the District. EBMUD does not allow water contact in the reservoir and sailing is therefore excluded as a possible use. Camping: Comment: oSEE MARINA SECTION FOR TRAILER CAMP o Don't expand the Chabot Family Campground because it would take away more open space. (It is under-used anyway.) 147 o Don't expand campground until demand justifies it. Response: o Expansion of the Chabot Family Campground on its southwestern end will only reduce the natural area by less than 1% and is therefore not significant. Expansion of the campground will not be made before there is a clear need identified; the cost/benefit factors are developed; and aesthetic improvements are made to the existing factors to improve their desirability. Development of the campground has been costly. Expansion there is more cost effective than creating another facility elsewhere in the District. Trail & Roads: Comment: o Reestablish a trail link from Skyline Blvd. equestrian trail (near Skyline High School) to the Big Bear Loop Trail. Response: o This trail link crosses property not owned by the District and would involve negotiations and possibly an agreement. The idea will be studied by the District. Comment: o Provide a link between Brandon Trail (at Willow Park parking area) and Live Oak Trail and inlet of Lake Chabot for local residents that need a shorter loop trail because they cannot hike the existing loop. This has been promised for a long time. Response: o This area has been studied in detail and a route is not possible. The existing trail at the bottom of the slope is within the golf course lease area and is used by golf carts and golf service vehicles. Non-golf use would conflict with golfing, especially at the tees. A trail located higher on the hillside would require severe cutting for a trail tread. This would result in unacceptable erosion problems. Comment: o Put a bridge in for equestrians like the joggers have at the junction of Eastshore Trail and Honker Bay Trail. Response: o This is a logical trail connection; however, it has not been included in the Plan because of the high cost of construction (estimated at approximately $400.000). Comment: o Legalize night hiking (at least in some areas). Response: o Ordinance 38 now establishes a curfew in all parks during nighttime hours. Closing time varies with the season. Since this is a District-wide proposal. it will be referred to the Park Advisory Committee and Board of Directors. 148 Comment: o Provide access to the EBMUD Chabot staging area other than on Redwood Road; maybe on an easement through Willow Park Golf Course along Redwood Road. Response: o Trail users adj acent to the golf course might disturb golfers. Thus, the golf course side of the road is not desirable for a trail. This area is also too steep for a trail, and golf balls would be a potential hazard for equestrians. Those not wanting to ride along Redwood Road should use the Brandon and Willow View Trails. Comment: o Keep Grovenor Gate only as service entrance. Response: o Grovenor Gate is not shown as a public access on the Plan. Comment: a Relocate Ten Hills Trail where it is adjacent to residences. Response: o Relocating the trail would put it in areas that are significantly steeper, making construction difficult. This would increase maintenance, as well as erosion and landslide potential. Equestrian: Cornments: o Provide a horse trough at Bart Meadow. o Design the equestrian camp so that camping, horse stalls and parking are all in the same area, particularly so that the horses are visible to the campers for security. The north end of the meadow was a good site in former years. o The existing site for horse stalls is good. o The existing site for horse stalls is bad. Response: o The Capital Improvement Plan will deal with the design details of the equestrian camp at Bart Meadow and leaders of the interested equestrian groups will be contacted for their input. The goal of the Plan will be to provide a good equestrian area that will provide for all of the equestrian needs (such as security and privacy) while not conflicting with other activities of the meadow. Picnicking Comment: o Provide a place where a few riders can tether their horses and picnic (without having to make an overnight reservation.) Response: o As stated in IILC.2.b.5. IiServices Along Trails". such facilities will be located within the park at reasonable intervals (see text for criteria). 149 Comment: o ----Provide family picnicking in Anthony Chabot somewhere along Marciel Road. Response: o See preceding response. A family picnic area for 25 to 30 families near the campground along Live Oak Trail has been added to the Plan. Miscellaneous: Comments: o Nike Hill not a good name. o No oaks on new trail named Acorn. Response: o Comments noted. Comment: o The park should be expanded. Response: o There are no current plans to expand this parkland. Many additional recreation opportunities are available within the EBRPD. There are almost 60, 000 acres of parkland (including Chabot) available for public use at this time. Specific acquisition proposals should be referred to the EBRPD Land Department. Environmental Impact Report Comment: o The traffic discussion does not include potential impacts on the State highway system. Response: o The traffic impact evaluation does not discuss impacts upon the State highway system. because no significant traffic impact would occur on any State highway. Comment: o The Soil Conservation Service has available. standards and specifications to reduce the unavoidable adverse impacts associated with grading and road construction. Response: a The Natural Resources Management Plan includes the use of erosion control measures. including the measures recommended by the SCS. However, total control of erosion is impossible, and therefore it is listed as an unavoidable adverse impact. Comment: o The SCS can work with the EBRPD staff to help avoid overgrazing. Response: o The EBRPD staff will continue to cooperate with the SCS in its administration of the grazing program. This mitigation measure is hereby incorporated into the EIR. 150 Comment: o The California Division of Forestry, through its Chaparral Management Program, can provide both technical and financial assistance in the execution of prescribed burning in brushland areas. Response: o The EBRPD staff will continue to cooperate with the CDF in the carrying out of a prescribed burning program. This mitigation measure is hereby incorporated into the EIR. Comment: o The Resource Conservation District has records of a cooperative agreement covering 1,300 acres of ACRP; this should be expanded to cover the entire park. Response: o The records of the EBRPD indicate that this agreement covers 4,600 acres; however, this agreement will be modified to cover the entire park. B.

We discuss some of them below. The L.U.D.P. mentions two other ranges within the 30 minute planning zone. One of those facilities has already closed and its patrons are shooting at Chabot. Because of high land costs, we do not anticipate the development of any new shooting ranges in the foreseeable future. Presently over 15 local police departments use the Club for training, in addition to many private and corporate security forces, schools and dis placed culbs. We operate programs for juniors, the handicapped, pistol safety and hunter safety. Our hunter safety program is the largest in the State of California. Unfortu nately, our present facilities are not adequate to meet the demands of East Bay shooters, both in terms of size and variety; thus our expansion request. We propose additional trap ranges. We have eliminated two additional 50 yd. pistol ranges, instead we are requesting two smaller 25 yd. pistol ranges beyond trap. We include associated parking and an access road to the above facilities. To further reduce our need for additional land, our present proposal superimposes the smallbore range on the 200 yd. silhouette range that the L.U.D.P. recommends. In addition, we propose a 500 meter/600 yd. range sited and constructed in a manner that will mitigate its sound and visual impact. At present, Metallic Silhouette is probably Lhe most popular type of competition. IHMSA, (International Handgun Metallic Silhouette Association) has approximately 600 members in the East Bay. It strongly supports our request for a 500 meter range. Currently. East Bay residents must drive to Reno, Nevada to shoot 500 meter silhouette. The 500 meter range would be superimposed on the 600 yd. range, which would be utilized for 600 yd. NRA competition. The silhouette shooters prefer a natural terrain and current design criteria for NRA competition allow up to a 4% grade. Utilizing the computer augmented topographic map recently· drawn for the Club. and calculating a 4% grade, we were able to reduce the amount of cut required to 10% of our previous proposal, or 38,000 cubic yds. at the impact area with balanced filIon site. The porposal includes the sound berm, recommended by the acoustic report of Wilson. Ihrig & Associates, which states. "This [the sound berm] would be sufficient to lower the noise level to a point where it should not exceed that which is presently experienced and it may actually reduce the noise to lower levels." The Chabot Gun Club is committed to achieve or exceed that goal. Our proposal will control erosion in numerous ways. First, slopes will be no greater than 2:1 and they will be planted with selected native plants indigenous to this area. The construction of a siltation pond and associated structures will further 154 .--. .... " f I '\ ~ / / / / I" , i \.

Currently we have 100 graveled parking spaces; dirt parking of 50 at the 200 meter range and an overflow parking capacity of 50. The proposal will add a total of 140 dirt parking spaces and replace the overflow parking with 50 graveled spaces. The 500 meter/600 yard range will probably be used twice a month. The High Power match draws 30 - 50 shooters and will probably see an increase to 40 - 60 shooters. The silhouette match usually draws 20 shooters, depending on the weather. This course of fire will probably see a larger increase, possibly up to 40 - 60 shooters per match. With the 500 meter/600 yard range would come two new types of competition, Long Range Rifle and Long Range Pistol silhouette with about 40 - 60 shooters per match. The only other new match we are proposing is the rimfire silhouette which will probably be popular as well. The other programs will probably all see some growth to fill the expanded facilities. This may sound confusing to a non-shooter so please feel free to call and I'll elaborate more. 158 " . January 6, 1984 Executive Director Richard Trudeau East Bay Regional Park District 11500 Skyline Boulevard Oakland, California 94619 Re: Chabot Regional Park Land-use Development Plan Dear Mr. Trudeau: Based on its national ORV policy, the Sierra Club opposes the District's plan to continue to allow motorcycle use in the motorcycle hill area and to "upgrade" the area for such use. The opposition is based on two very detrimental effects of motorcycle use: noise and destruction of natural habitat. Dirt bikes, some of which are unmufflered, are very noisy and can be heard in many areas of the park as well as other adjacent areas. Such noise makes it very difficult to fully enjoy an outdoors or wilderness experience. The noise also has a deleterious effect on wildlife. The effects of motorcycle use on the land and vegetation are obvious from an Bxamination of the existing condition of the motorcycle area. What better example of the reason for prohibiting such use in this area is necessary since the use caused the erosion problems. Erosion control should be implemented but will never be adequate while the area is being chewed up by motor cycles. In summary, motorcycle use is incompatible with all other uses of the Park and should be prohibited. An additional consideration that should concern the Board is the increased expense that will result from continued and increased use by motorcyclists. The area will require more patrolling and cleanup in addition to the expense of the planned facilities.

Real attempts should be made to reduce the noise level polution rather than increasing the noise level by possibly using heavier armllunition for longer ranges. Beside the fact that the noise is not pleas,,,nt, one wonders what it does to the aninlals as well as park users close to the range when it is used. h. The Marina. It is felt, by the Association, that the Marina is now being advertised with a large sign giving it a commercial slant. Traffic is becoming a problenl.

The review period is closed and the co~ ments of the individual agency(ies) is(are) attached. If you would like to discuss their concerns and recommendations, please contact the staff from the appropriate agency(ies). When preparing the final EIR, you must include all comments and responses (CEQA Guidelines, Section 15146). The certified Era must be considered in the decision making process for the project. In addition, we urge you to respond directly to the commenting agency(ies) by writing to them, including the State Clearinghouse number on all correspondence. A 1981 Appellate Court decision in Cleary v. County of Stanislaus (118 Cal. App. 3d 348) clarified requirements for responding to review comments. Specifically, the court indicated that comments must be addressed in detail, giving reasons why the specific comments and suggestions were not accepted. The responses must show factors of overriding significance which required the suggestion or comment to be rejected. Responses to comments must not be conclu8ory statements but must be supported by em pirical or experimental data, scientific authority or explanatory information of any kind. The court further said that the responses must be a good faith, reasoned analysis. In the event that the project is approved without adequate m1tlgatiou of significant effects, the lead agency must make written findings for each significant effect and it must support its actions with a written statement of overriding considerations for each unmitigated significant effect (CEQA Guidelines Section 15088 and 15089). If the project requires discretionary approval from any state agency, the Notice of Determination must be filed with the Secretary for Resources, as well as with the County Clerk.

Frydendal, ;ve reviewed the draft land use development plan for Anthony Chabot Regional Park. The Park District has incorporated the Resource Con servation District's recommendations which were sent August 31, 1982. The Land Use Development Plan also includes recommendations made by the Soil Conservation Service on erosion control and brushland im provement. The Land Use Development Plan, if adopted, will place a high priority 011 erosion control on roads and trails. The Plan requires erosion control plans as part of any capital improvement projects and as part of the timber harvest plans. Four items which should be discussed with the Park District further are as follows. 1. The LUDP lists as an unavoidable adverse impact increases in erosion for the first two years following a grading project. The Soil Conservation Service has standards and specifications for temporary erosion control on construction sites and access roads. '1 '-. :he LUDF mentions the potential for over grazing if t~e cattle are mismanaged. We have worked closely with Neil Havlik on developing grazing guidelines, stockwater developments, and fencing at Sunol Regional Park. The same type of plan could be developed for Chabot. 3. Prescribed burning is recommended for parts of the Park in the LUPD. The California Department of Forestry has a great deal of experience with controlled burns and should be consulted. In addition, CDF offers the Chaparral Management Program which cost-shares up to 90% of the cost of a burn program. 4. The Resource Conservation Districts existing cooperative agreement with EBRPD for Chabot Regional Park covers 1300 acres. The Park now includes 4,674 acres and will expand to 5,096.58 acres if the Land Use Development Plan is adopted. • ~~ Luana Kiger Soil Conservationist , "U LARRY T. WILKINS F.F.

As President of the Presidio Gun Club~ numbering 100 members, the facilities are an extention for outdoor marksmanship train ing for our indoor programs. These programs are of the International style and our club counts in its membership, 2 Olympic Champions and 2 World Class shooters, 1 in International Rapid Fire and one in Ladies Sport Pistol. The last two are both in training for the Summer Olympics in Los Angeles. The Presidio Gun Club and the Chabot Gun Club are co-hosting the California State Outdoor Pistol Championships in May of 1984. At this Championship will be most of the competitors now in training for the Summer Olympics. Please consider any and all support possible for the expansion and up grading of the facilities as they aid in Junior Programs and aid in the mental disipline of the shooting sport. Thank you. ----~Fj;ir~~L---? /' Larry Wilkins President, Presidio Gun Club 172 APPENDIX E RECONNENDATIONS OF THE EBRPD EDUCATIONAL, USE ADVISORY COHNITTEE regarding ANTHONY CHABOT REGION.i"\L PARK December 5, 1983 Meeting ~ at which Committee considered this park: Feb.ll, 1982. with subsequent delineation of two boundaries on: Jan.11,19B3. Educational/ResearchLStudy Areas Recommended by consensus of the 14 members of the Committee present are as follows, with the rationale for each: [Boundaries of each are ShO~l in green on the photo-map returned herewith] 1). The ENTIRE HEAD OF GRASS VALLEY plus ACROSS ADJACENT RIDGES TO THE NORTH WEST AND NORTHEAST, exclusive of buffer strips as noted. The boundaries recommended would extend approximately perpendicularly to Grass Valley Creek at about 200 feet above the limits of any Recreation Unit develop ment to be done at Bort Meadow, to the edge of Redwood Road right-of-way from the MacDonald Trail staging area around to intersect the northeast extension of the boundary across Grass Valley, and to a line on the south west which would exclude Skyline Trail from the designated E/R/S Area. The north"l'rest part of MacDonald and Grass Valley Trails wnuld thus traverse the E/R/S Area, as well as several local trails (one of Which, on the northeast-facing slope above Redwood Road, provides the closest access to coast redwood trees there). These trails could be readily reached by researchers from the MacDonald Staging Area, from parkridge Gate, or by a short hike from Redwood Road past Bort Meadow. If the fuel break along the southwest border of this park is ever extended northwestward, it would still leave a significantly large and valuable study area. Some members of the committee felt that there is no need for clearing of vegetation of the moist shrub types for such a project, inasmuch as they are hardly ever burned in a fire. Rationale: The head of Grass Valley includes various coastal scrub areas as well as grasslands and patches of broadleaf evergreen woods, and thus provides opportunities close to the immediate East Bay educa tional institutions for study of these common plant communities and their typical animals. Ecological succession continuing in the area since it was removed from grazing in the 1950s is also of interest if it is to remain free of grazing by domestic stock. The extension north\,lTest onto the Redwood Creek drainage includes a large area where coastal scrub merges into more moist shrub types (un-named as a community) and with larger trees in the canyons. The frequent use of this area by hikers and equestrians along the trails would not conflict with research at sites that could be mostly hidden from the trailS themselves. Plant and bird diversity in the area are both high. The extension northerly and northeastward over the north part of Chabot Ridge inclUdes the ecotone between the southern end of redwood forest (of the East Bay Hills) and the live-oak - laurel - madrone forest, with additional interspersed patches of shrubs. Ecotones and areas of range-limits (as here of the coast redwood) are of special importance for ecological studies. 2). The EAST INLET OF LAKE CHABO'I' and CA,.I'-JYONS AND HILLTOPS '1'0 THE SOUTH. Boundaries of this area would be from a buffer strip (estimated 100-200 feet) along Ten Hills Trail and tr~ northerly edges of the Corporation Yard and Public Safety Headquarters north to include the entire head of Lake Chabot (near the Cameron Trail lOOp) and east to the golf course boundary. On the west, beyond the Cameron Trail junction with the East shore Trail, the boundary could be along the 1m.'1er half of the slopes to avoid conflict with with the heavy use of that paved trail. 173 Rationale: This proposed E!R/S Area includes several opportunities for study of ecological succession in stages not readily found in most parts of the East Bay area. First, the inlet of Lake Chabot has all stages of the development of plant communities in open water to marshes and in creasing riparian woodland. Later stages of the latter developing into upland types of forest/woodland were removed when the golf course was built; but the hydrosere example here is,even so, the most complete of any in the EBRPD. Mature, but irregularly fire-affected, areas of live-oak laurel forest occupy most of the steeper northerly-facing slopes of the canyons. Bordering these are areas of old coastal scrub (mostlY coyote brush) in which many of the shrubs are dying, while young live-oak and laurel trees are growing vigorously. Opportunities to watch this develOp ment will last only as long as such brush areas are ~ again burned, even though a fire may be considered to be a natural event in such vegetation. Also included are considerable areas of native perennial grasses (StipaL ElTInus) on gently-sloping ridges northwest of the Public Safety headquar ters. While one fire would not be expected to remove these native spe cies, repeated burning and especially grazing would probably result in encouraging introduced annuals at the expense of the perennials. The proposed E/R/S Area as a whole has apparently been free of heavy grazing for many years and as such is very worthwhile for studies needing such a "base" against which to compare lands not so protected .. 3). An AREA FOR STUDY OF EUCALYPTUS and ADJACENT NATIVE WOODLANDS, SWof northern part of Marciel Roade Boundaries (as drawn by H.L.C. after a hike through the area and presented to the committee in Jan.1g83) would extend from Red-tail Trail or Marciel Road for about 3000 feet west to southwesterly to include the native tree zone along Grass Valley Creek, and thus to encompass in the E/R/S Area two spurs of Chabot Ridge each of which divides into two above Brandon 'frail. Three tributary canyons of Grass Valley Creek are thus included in the lower part of the area. The southeast boundary is kept one canyon and one ridge away from the marks manship range, at which distance the noise of the latter is moderated. Rationale: Despite extensive discussions of the parkland values of Euca lyptus as well as the fire hazards which large groves of these introduced trees present, there has been little study of the basic ecology of these groves (planted 'tvidely in the East Bay beginning in the 1870 IS) • The de gree to which various wildlife species use these trees and associated understory and litter has not been quantified. Nor have the successional relationships "ivith native species of trees and shrubs ("more desirablell to some) been investigatede The area here selected is ideally situated for investigations of all these features and readily available on foot in all weather from Marciel Road, or by a longer hike from Skyline Blvd. The committee was aware of the proposed fuel-management program in Chabot Regional Park~ If the E/R/S Area here reco~nended is so designated by the Board, the Committee further recommends that notice be given well in advance of any prescribed burning (or other alteration) of the Eucalyptus groves within it so as to enable any interested researchers to gather per tinent data both before and after such procedures~ Drafted for the Committee, Dec.5,1983, Jiff. by Howard L.
