FOREWORD

Carquinez Strait channels waters flowing from Sierran snow beds through the vast fields of the Central Valley to meet the salt waters of the Pacific Ocean in the San Fran­ cisco Bay. The broad streams of the San Joaquin and Sacramento Rivers converge in the Carquinez Strait and along their course supply water for over two thirds of California residents. Much of this immense ancient water system is visible from the bluffs rising above the Carquinez Strait Regional Shoreline.

We usually speed by these waters on freeways or over them on bridges, catching a glimpse of sailboats on the way to somewhere else. At Carquinez Strait Regional Shoreline one can sit quietly under coastal bluffs next to the water's edge and contrast the relatively recent trappi1\gs of human history, the factories, subdivisions, railroads and ships, to the larger, more permanent forces of nature at this northern border of the Bay.

This waterfront area offers tremendous potential for recreation, preservation of natural resources and education. The diversity of resources is reflected in the special aspects of the park's location; its views, open water, trail system, marine climate and historic buildings. It is the water oriented and water dependent attributes that make this site so unique - an area of truly regional significance.

To determine the feasibility of Carquinez Strait Regional Shoreline to function as a park, it is necessary to understand the natural and cultural features that the area pos­ sesses; for these are the primary materials from which the park is to be made. The purpose of the Resource Analysis is to describe and locate those features that are most crucial to the development of a plan that will preserve the park's natural resources and develop its recreational opportunities: topography, slope, hydrology, vegetation, wildlife, soils, geology, visual attributes, roadways, trails and cultural resources. This information will form the foundation upon which the Land Use-Development Plan will be built.

The Port Costa Unit encom­ passes grassland rising above both sides of the town of Port Costa and forming a continuous open space west to Crockett. This site consists of open rolling grasslands, the wooded ravine of Bull Valley, eucalyptus groves and river shore­ line access at the former Eckley townsite. The remnants of a former brickworks, grain wharf and resort, dating back to the tum of the cen­ tury, recall the historic character of the site. The Crockett Hills Unit ascends steeply from the south side of Carquinez Scenic Drive to an elevation of 700 feet. This unit contains scenic ridgeland at the end of Dupuru Street, a resi­ dential road. This park unit is not open for public use.

The area has historically remained in agricul­ ture and grazing land use because of its steep topography. These coastal hills rise from sea level up to 750 feet and are the predominant

Although results were variable and may be somewhat elevated, County Health offi­ cials typically require remediation only when lead in soil exceeds 100mg/ kg due to potential exposure and health concerns. Other potential problem areas of concern regarding sources of soil and/ or groundwater contamination that could af­ fect parkland uses include the former Tosco refined petroleum storage tank farm adja­ cent to Port Costa Clay Products and the OZOL Fuel Terminal.

• Ground water contamination at Ozol terminal will require remediation by Regional Water Quality Control Board (RWQCB).

• Soil and ground water contamination could affect parkland use and shoreline recreation.

• Spring development is needed for livestock grazing.

• There is an inadequate supply of drinking water for park users.

But Landslide damage on Carquinez Scenic Dri'De Schwartz et a1 (1992) believe that it is capable of generating magnitude 7 quakes, the last of which may have been during 1808. Although no definitive information exists to date on whether an earthquake will occur on one of these faults, the potential for displacement to occur along faults that are proximal to active faults is certainly possible. This has been indicated by field evidence from the Loma Prieta quake. Thus, caution is advised for any improvements crossing the Southhatnpton Fault in the Franklin Hills Unit.

The Hayward, Calaveras and San Andreas Faults are all capable of generating earth­ quakes larger than magnitude 7, the greatest of which would be from the latter, on the order of an 8.3 magnitude. Maximum tnagni­ tude quakes from any of these faults could ,cause sufficient damage to structures, foun­ dations and utility lines, particularly those constructed upon non-engineered fill or upon ,bay muds near the shoreline.

Resource Issues

• In the absence of a mechanism to control herbaceous vegetation growth, most productive non-native grassland and some woodland understory sites accumulate large amounts of plant material, which acts as a mulch to diminish native herba­ ceous plant diversity and increase the risk of wildfire. Some sites may be subject to encroachment by weed and brush spe­ cies, such as mustard, fennel, poison oak, coyote brush, and broom.

• The conselVation and protection of rare plant populations on the park will require appropriate management that addresses the individual requirements of the plants and their habitats. Addi­ tional, focused, field surveys of park flora are necessary to identify significant plant species and communities on the park.

• Appropriate management is necessary to preserve and enhance riparian and other wetland resources on the park.

• The fragility of the White's Resort drain­ age warrants concern for its continued protection, especially in developing public access to the fishing pier.

• Two animal species listed by the state as "species of special concern" have been found as residents of the park. The first is the Cooper's Hawk (Accipiter cooperz) which nests in the dense woodlands in the former McNear property. The other is the

There are two possible locations of the main village of the Karkin. One site may have occupied the eastern edge of Crockett. The Karkins, who controlled both sides of the Strait, may have had a main village in the Benicia area. In either case, it appears that the south shore of the Strait and the hills that extend over to Franklin Canyon were in an area primarily used for hunting and gather­ ing, not for tempor~ camp sites or more permanent villages. The only prehistoric sites which have been recorded inthe general vicinity of the southern shore of the Strait are at the Ozol Fuel Depot and on the edge of Rankin Park in Martinez. There may have been additional midden sites on either the western or eastern peripheries of the shore­

Teodora Soto, claimant for Rancho Canada del Hambre, was granted 13,312.7acresbyJuanB.Alvarado on May 18, 1842. In 1860 half of the land was sold to William Piper. John Eckley bought 374 acres of this land in 1870. (See section lI.B Land Use History for a description of the settlement of Eckley and the development of the grain and shipping industry along the strait.)

Four relatively recent historic phases have been identified on the former Eckley townsite: 1) the Eckley homestead (c. 1870-1889); 2) the development of George McNear's grain ware­ house (c. 1880-1942); 3) construction of the Carquinez Brick and Tile Company (c. 1880- 1942) and 4) operation of a fishing resort (c. 1921-1970). Historic sites of varying types exist at several other locations in the park. Eckley townsite ruins, brick office Eckley Townsite building and grain warehouse

The grain warehouse, house and office, (courtesy of Contra Costa County Historical Society) built by the Granger's Business Association sometime between 1880 and 1889 are consid­ ered historically significant. These buildings are located along the water's edge, north of the railroad tracks. Despite extensive fire damage to the warehouse itself, the charred wood pilings still supporting the building's structure over the waters ofthe Strait conveys to observers the original appearance and feel­ ing of the place. Also evoking the presence of early industrial activity on this site is the one­ story brick building used to house the office of the Carquinez Brick and Tile Company.

Left to deteriorate after the decline of the sport fishing business, the "Garden City" burned in 1983.

Three residences and several buildings asso­ ciated with the fishing resort phase of the site (dating from the 1940's) were demolished by EBRPD when the Maguire parcel was ac­ quired in 1988. These buildings had been used as residences since the early 1970' s and were considered attractive nuisances in their dilapidated condition. A building survey by a qualified architectural historian determined that they offered no or insignificant architec­ tural or historical interest.

4.1 White's Resort

White's Resort was built about 40-50 years ago as a riverside resort, and included a boat dock and fishing pier built over the water. Other buildings on the site include a bait shop / snack bar, sheds, out-buildings and a single family residence located inboard of the railroad tracks. These 15uildiitgs have little historical or architectural significance. How­ ever, White's Resort does contain a unique historic feature. Over the years of operation of the Resort tons of brick were hauled in and used to pave the road leading from the cluster of shoreline buildings up a small canyon, eventually turning south to a clearing. The visible portions of this paved road show a combination of overlapped dry laid brick merging at points into a herringbone design. This section of paved roadway is probably the longest intact brick road in Contra Costa County.

3. Resource Issues

• Evaluate the grain warehouse and ferry "Garden City" ruins and brick office building for restoration and public in­ terpretation.

• Evaluate the brick road at Whites Resort for preservation and protection.

• Recognize the abundant physical evidence of California's grain shipping operation and other water related history (fishing resorts, ferries) along the Strait in the planning and interpretation of this park

• Evaluate the brick office building and Eckley snack shop for conversion to park uses.

Other visitors came from Concord, Lafayette, Moraga, Pied­ mont, San Jose, Walnut Creek, Vallejo, Benicia, Marin, Hercules, Oakland, Pinole,Richmond, Rodeo,Sausalito, San Pablo, San Mateo, Pleasant Hill and San Francisco.

• Twice as many people enter Carquinez Strait Regional Shoreline at the Bull Valley Staging Area than at the Nejedly Staging Area.

• Tilden, Briones and Martinez Shoreline were the other regional parks most vis­ ited.

• The park's location was the key attrac­ tion followed by views, trails, open land, proximity to the shoreline and lack of traffic.

2. Resource Issues

• Consider restoring shoreline related fa­ cilities (boat docks and fishing piers) to Eckley and White's Resort.

• Identify suitable locations for family picnic sites and drinking fountains.

• Provide for the interpretation of: the historical and archaeological use of the area; the hydrodynamics of the Northern Beach at Eckley California watershed; and the importance of the strait to the bay and delta.

53 D. SERVICE FACILITIES AND UTILITIES

1. Police Protection

Carquinez Strait Regional Shoreline receives full police seIVices from EBRPD's Public Safety Department, the primary law enforcing au­ thority for the parks. City of Martinez police are capable of providing a three to five minute response time to most areas within Carquinez Strait. Martinez police patrol the area to the east of the Nejedly Staging Area and the Contra Costa County Sheriff's Department provides services to the unincorporated towns of Crockett and Port Costa within and to the west of the park The California Highway Patrol has jurisdiction on roadways in unincorporated portions of the county. The Contra Costa Sheriff and the Coast Guard Residence at Eckley Shoreline patrol the waters of the strait, providing emer­ gency rescue assistance. The open parklands along the ridge are also patrolled by the 2. Fire Protection District's helicopter. Fire protection services are provided by four A three year review of law enforcement inci­ agencies in the vicinity of Carquinez Strait dents at Carquinez Strait indicate mostly Regional Shoreline.

There is no District service yard at Carquinez Strait Regional Shoreline. The park is ser­ viced by District field staff housed at the maintenance yard located in Martinez, less than one mile from the Nejedly Staging Area.

7. Resource Issues

• Remove or rebuild piers to reduce safety hazards.

Identify critical fire hazard areas along park boundary and plan strategies to handle fires.

Evaluate impact of Carquinez Scenic Drive road closure in the reduction of car accidents and public safety viola­ tions.

Develop water resources in the park to benefit wildlife, fire management and equestrian use.

Develop drinking water facilities at staging areas and new recreation facili­ ties for park users.

Remove or upgrade unsafe cesspool at White's Resort prior to public use.

• Consider consolidating overhead utilities into one corridor or placing them under­ ground where possible.

APPENDIX A

PURPOSE AND ROLE OF THE EAST BAY REGIONAL PARK DISTRICT

The East Bay Regional Park District ("EBRPD" or "District") is a State authorized special district within Contra Costa and Alameda Counties. The District encompasses 49 parIdands on approximately 71,063 acres of land. The District derives its powers from the State Public Resources Code, Sections 5500-5595. These sections: (1) established the District; (2) set procedures for acquiring, using and disposing of District property; (3) empower the District with design and maintenance ofthe system; (4) establish wards, the Board ofDirectors , officers and the right to employ staff; (5) give the District the right of eminent domain; (6) give the power to create ordinances, resolutions and motions; and (7) give the power to tax.

The EBRPD is governed by an elected Board of Directors. The Board is responsible for establishing policies and objectives, as necessary, to accomplish the District's purposes. The District's policies and objectives are: (1) to provide a diversified land and water system of regional parks; (2) to acquire, preserve and interpret significant examples of the natural environment; (3) to cooperate with other public agencies in the development of non-park open space lands; (4) to emphasize balance ofboth environmental concerns and regional recreation opportunities; and (5) to develop a dispersed parIdands system close to the people.

An Environmental Impact Report (EIR) was prepared in 1989 for the Carquinez Shoreline Trail and the NejedlyStaging Area (the former Sacchi property). This document was pre­ pared by EBRPD in compliance with the Cali­ fornia Environmental Quality Act (CEQA). This EIR was prepared to inform the public aboutthe potential significant environmental effects of the staging area to the east side of Carquinez Strait Regional Shoreline and the trail connecting the staging area to the city of Martinez' Rankin Park and the California Riding and Hiking Trail. The EIR was certi­ fied by the Board of Directors on March 7, 1989.

RANGE ANALYSIS

The following pages include range analysis reports generated for the various grazing units on Carquinez Strait Regional Shoreline. The range analysis process is used to estimate forage production and determine the number of animals that can be supported on a given area of land consistent with resource conservation objectives. Where historical or current grazing records are available, the process is used to verify whether existing use levels are adequate, or whether adjustments are necessary. Where this information is unavailable, the analysis offers a reliable method for establishing an initial stocking rate.

The range analysis is based on information contained within the USDA Soil Conservation Service soil surveys of Alameda and Contra Costa Counties. The soil surveys group soils into "range sites" on the basis of similarities in texture, depth and slope. Forage production estimates for favorable and unfavorable rainfall years are provided in pounds per acre for each range site. This information is used in conjunction with vegetation data collected in the field to prepare the final reports.

The process incorporates residual dry matter standards, which are used to determine the amount of vegetation that should remain on the ground at the end of the grazing season. This residue or mulch acts as a protective layer over the soil to guard against erosion, encourage nutrient recycling and promote optimum conditions for plant growth. Total forage production minus residual dry matter equals the amount offorage actually available for livestock to consume.

Additional adjustments in stocking levels may be necessary in situations where steep terrain and/ or the lack of available drinking water limit or preclude grazing use on certain areas of the parks where forage is otherwise available. Areas of high recreation use, wetlands and sites containing notable resources may also require exclusion from livestock use.

Once a stocking rate has been established, use levels can be changed to reflect existing conditions. Plant production and species composition can fluctuate drastically from year to year in response to temperature differences and the timing and amount of rainfall during the growing season, and some adjustments in stocking levels are usually necessary to ensure that grazing occurs within established standards. The District's Range Manager conducts periodic inspections of the park during the grazing season to determine if grazing use needs to be modified to achieve proper utilization.
