6. General Plan Designation: General Industrial

7. Zoning: IG(S)-Industrial General

Project Description: The City of San Leandro, Kaiser Foundation Hospitals (Kaiser), and ICI Development Company (ICI), are undertaking review of a significant project to be located on a 65-acre site near I-880 and Marina Boulevard. The northern approximately 30 acres of the site would be developed with a 387,000-square foot retail project (consisting of large format stores, multi-tenant retail uses, restaurants, soft goods, and service-oriented retailers) and a mixed-use residential project (consisting of up to 250 one- and two-bedroom apartments and 25,000 square feet of retail uses). The southern approximately 35 acres of the site would include up to 865,000 square feet of medical uses to be developed by Kaiser. The medical uses to be developed by Kaiser would include a 434,000-square foot, six-story, 262-bed hospital; a 400,000-square foot, six-story hospital support building; a 35,000- square foot central utility plant; a 20,000-square foot outdoor service yard; and parking necessary to meet projected demand, estimated to be no more than 2,510 stalls. Parking facilities could include surface parking and an additional 800-stall, five-story parking structure.

Kaiser Permanente San Leandro Medical Center/Marina Point Mixed-use Development Project Initial Study Page 1 P:\Projects - All Employees\D40000.00+\D41268.00 ICI San Leandro\Initial Study\Kaiser San Leandro Medical Center-Marina Point IS.DOC The project will also include the following roadway improvements: the widening of Merced Street to the east along the project site frontage; an eastern extension of Republic Avenue into the project site and the signalization of the Republic Avenue/Merced Street intersection; and a new signalized intersection at the main entrance to the proposed mixed-use development site along Merced Street.

The project site is currently owned by Kaiser and is occupied by the former Albertson’s supermarkets distribution and maintenance center and various warehouse distribution and industrial uses. Prior to the submittal of this application, Kaiser had submitted a separate application to the City of San Leandro for the demolition and grading of all structures on the Kaiser site. Therefore, for the purposes of this analysis, it is assumed that the Kaiser portion of the project site will be cleared of structures and rough graded prior to or concurrently with the approval of the project. Potential development of the site with the ICI development and the medical uses would require the creation of a new General Plan land use designation and zoning district.

Affected Assessor’s Parcel Numbers include: 077A-0647-001-38; 077A-0647-001-37; 077A-0647-001- 36; 077A-0647-001-35; 077A-0647-001-34; 077A-0647-001-27; 077A-0647-009-27; 077A-0647-009- 32; 077A-0647-009-35; 077A-0647-009-37; 077A-0647-009-42; 077A-0647-009-45; and portions of 077A-0647-012-01; 077A-0647-012-02; 077A-0647-012-03.

8. Surrounding Land Uses and Setting: The project area is bounded by the I-880 freeway right-of-way to the east, Marina Boulevard to the north, Merced Street to the West, and Fairway Drive to the South. The site is served by the Marina Boulevard and the Davis Street interchanges with I-880. The land uses immediately surrounding the project site are primarily industrial and commercial. Land uses east of I-880 include residential; a commercial shopping center; and the San Leandro Ball Park and Pacific Recreation Complex. Residential land uses are also present further west and further south of the project site.

Potentially Significant Potentially without Less than Significant Mitigation Significant No Issues: Impact Incorporated Impact Impact Source I. AESTHETICS– Would the project: a) Have a substantial adverse effect on a scenic 1, 2 vista? b) Substantially damage scenic resources, 1, 2, 3, 4 including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? c) Substantially degrade the existing visual 1, 2 character or quality of the site and its surroundings? d) Create a new source of substantial light or 1, 2 glare which would adversely affect day or nighttime views in the area?

Discussion

a-b) The proposed project site is in a relatively flat area of northwest San Leandro. The surrounding area is characterized by one- and two-story concrete warehouses. Most buildings extend to the sidewalk. However, there are periodic breaks in the street façade due to the presence of surface parking lots. There is limited natural landscaping in the project vicinity. A small cluster of mature trees is on the northeast edge of the project site near I-880 as well as limited ornamental landscaping in the form of mature trees surrounding buildings and parking lots. The project site is visible from I-880 on the east and areas immediately east of I-880, as well as from surrounding roadways and adjacent development. Distant views to and from the project site are limited due the flat topography and the presence of buildings. However, the East Bay Hills are visible from some areas of the project site.

There are no designated scenic vistas or scenic resources on or adjacent to the project area. I-880 is not a designated state scenic highway in the project vicinity. Accordingly, the proposed project would have no impact on scenic resources nor damage scenic resources within a state scenic highway. c) The proposed project could change the visual character and quality of the project site. The proposed development of the project site would introduce more intensive uses, thereby introducing visual elements and features that could contrast with the existing visual landscape creating a potentially significant impact. Accordingly, the EIR will discuss the visual effects of the proposed project on existing development in the project vicinity. This discussion will include the creation of visual simulations. d) Existing lighting in the vicinity of the project site is characterized by low-intensity security and safety lighting along walkways, within parking lots, and at building entrances. Although no lighting plans have been created for the proposed project, development at the project site would include nighttime and security lighting characteristic of existing development. However, the new buildings may involve lighting designs or construction materials that could increase potential light and glare impacts for neighboring uses and motorists. This could be considered a potentially significant impact. Therefore, the EIR will discuss potential light and glare impacts associated with the proposed project.

Potentially Significant Potentially Unless Less than Significant Mitigation Significant No Issues: Impact Incorporated Impact Impact Source II. AGRICULTURE RESOURCES - In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Dept. of Conservation as an optional model to use in assessing impacts on agriculture and farmland. Would the project: a) Convert Prime Farmland, Unique Farmland, 1, 2, 3, 5, or Farmland of Statewide Importance 6 (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? b) Conflict with existing zoning for agricultural 1, 2, 3, 5, use, or a Williamson Act contract? 6 c) Involve other changes in the existing 1, 2, 3, 5, environment which, due to their location or 6 nature, could result in conversion of Farmland, to non-agricultural use?

Discussion

a) The project site is not on or adjacent to any farmland. Therefore, the proposed project would not convert or have the potential to convert existing farmland to a nonagricultural use, and the proposed project would result in no impact on important farmlands. b, c) The project site is not currently protected under the Williamson Act or zoned for agricultural uses. All properties to be directly or indirectly impacted by the proposed project are zoned for a variety of retail, industrial, and warehouse uses. Therefore, the proposed project would result in no impact to agricultural resources.

Potentially Significant Potentially Unless Less than Significant Mitigation Significant No Issues: Impact Incorporated Impact Impact Source III. AIR QUALITY – Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the project: a) Conflict with or obstruct implementation of 1 the applicable air quality plan?

Kaiser Permanente San Leandro Medical Center/Marina Point Mixed-use Development Project Initial Study Page 6 P:\Projects - All Employees\D40000.00+\D41268.00 ICI San Leandro\Initial Study\Kaiser San Leandro Medical Center-Marina Point IS.DOC Potentially Significant Potentially Unless Less than Significant Mitigation Significant No Issues: Impact Incorporated Impact Impact Source b) Violate any air quality standard or contribute 1 substantially to an existing or projected air quality violation? c) Result in a cumulatively considerable net 1 increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? d) Expose sensitive receptors to substantial 1 pollutant concentrations? e) Create objectionable odors affecting a 1 substantial number of people?

Discussion

a-e) The proposed project could intensify existing land uses at the project site and permit a range of commercial, residential, and hospital uses that do not currently exist in the project vicinity. The traffic related to the new residents, employees, visitors, and patients attracted to the site could result in additional regional air emissions. This increase in emissions could contribute to local traffic congestion that may result in “hotspots” of localized air pollutants such as carbon monoxide. In addition, construction activities involved in the development of the new mixed uses would emit particulate matter and construction equipment exhausts. Also, new uses, including the hospital uses, could create odors that may disturb any sensitive receptors near the project area. Because of potential new uses, the proposed project may hinder efforts to attain state and federal air quality standards for ozone and small particulate matter, for which the Bay Area is in nonattainment. Any of these effects would be considered potentially-significant impacts. Accordingly, air-quality related concerns will be examined in the EIR.

Potentially Significant Potentially Unless Less than Significant Mitigation Significant No Issues: Impact Incorporated Impact Impact Source IV. BIOLOGICAL RESOURCES – Would the project: a) Have a substantial adverse effect on either 1, 2 directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Services? b) Have a substantial adverse effect on any 1, 2 riparian habitat or other sensitive natural community identified in local or regional plans, policies, and regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Services?

Discussion

a-b) A query of the California Natural Diversity Database (CNDDB) for the U.S. Geological Survey (USGS) San Leandro, Hayward, Oakland East, Oakland West, Las Trampas Ridge and Newark 7.5- minute quadrangles resulted in records for 82 special-status plant and animal species, and four sensitive natural communities (Appendix A). This database includes species listed as rare, threatened, endangered, or proposed for listing as such, under the California and Federal Endangered Species Acts, species of special concern to California Department of Fish and Game (CDFG), and plants on the California Native Plant Society (CNPS) list 1 or 2 (considered rare or endangered within California and elsewhere). In general, the extensive species lists generated by the CNDDB and CNPS queries are the result of:

1. Populations of sensitive species associated with freshwater wetlands and undisturbed native grasslands found within the region (primarily east of the project site); and

2. Species associated with the brackish and freshwater habitats of San Francisco Bay (approximately one mile west of the project site).

Although the distance to some of these known resources is less than two miles, the project site is separated in all directions from any natural habitats by extensive residential, commercial, and industrial development. Therefore, it is extremely unlikely that any special status animal species would use the project site for nesting, cover, or foraging habitat. Plant species observed within and adjacent to the project site during the December 11, 2007 biological survey are limited to ornamental species confined to limited landscaping on the property, and introduced weedy annual grasses and forbs occurring in pavement cracks, or other highly disturbed unpaved areas.

Kaiser Permanente San Leandro Medical Center/Marina Point Mixed-use Development Project Initial Study Page 8 P:\Projects - All Employees\D40000.00+\D41268.00 ICI San Leandro\Initial Study\Kaiser San Leandro Medical Center-Marina Point IS.DOC No sensitive natural communities such as vernal pools, marshes or riparian areas are present within, or adjacent to the project boundaries. Therefore, implementation of the proposed project would not result in impacts on any special-status plant or wildlife species, or on any sensitive natural communities.

An examination of the limited number of trees and shrubs on the site during the biological survey did not reveal the presence of any nests of birds protected by the Migratory Bird Treaty Act. However, any project activities that would result in the removal of existing woody vegetation could potentially impact nesting birds (i.e., the loss of young birds or the abandonment of an active nest), which would be a violation of Fish and Game Code Section 3503 and the federal Migratory Bird Treaty Act and would be potentially significant impact.

Mitigation Measure. Implementation of Mitigation Measure BIO-1 would reduce potential impacts to nesting birds to a less-than-significant level.

BIO-1. Conduct pre-construction surveys for the presence of nesting birds. The project applicants shall retain a qualified biologist to conduct a pre-construction breeding-season survey (approximately February 1 through August 31) to determine if any birds are nesting on or directly adjacent to the project area. The survey shall be conducted during the same calendar year that construction is planned to begin. If no nesting birds are found, then no further action would be required.

If nesting birds are found within the trees on or directly adjacent to the project area, the project applicants shall avoid all birds nest sites located in the project area during the breeding season (approximately February 1 through August 31), or until it is determined by a qualified biologist that all young have fully fledged (left the nest). If the construction cannot be delayed, avoidance shall include the establishment of a non-disturbance buffer zone around the nest site. The size of the buffer zone will be determined in consultation with the CDFG. The buffer zone shall be delineated by highly visible temporary construction fencing, and shall remain in place until it is determined by a qualified biologist that all young have fully fledged (left the nest). c) No “wetlands or other waters of the United States” are present within, or adjacent to the project boundaries. A single shallow, open drainage ditch occurring in the northwestern portion of the project site is an artificial drainage feature constructed in an upland area. Pursuant to the Supreme Court Decision; Rapanos, et al. v. United States, No. 04-1034, such drainage features do not meet the definition of “wetlands or other waters of the United States,” Implementation of the proposed project would therefore not result in a substantial adverse effect on any wetland protected by state or federal regulations. d) Historically, the project site was completely developed. Therefore neither it or the surrounding areas serve as a migratory corridor for native species; nor does the project site provide nesting sites for wildlife species. Therefore, no further analysis is necessary. e) The City of San Leandro does not require tree removal permits on private property, though they do strongly encourage the preservation and care of such trees. The City does provide some protection for any large “heritage” trees in the City as long as they remain healthy and do not pose a hazard to nearby properties. Trees occur in only small landscaped areas in the northern portion of the site. These trees are ornamental species that are relatively young, and would not qualify as “heritage” trees. Implementation of the proposed project will not result in conflicts with any local tree protection ordinances, and is likely to result in an increase in tree cover in the area as larger portions of the property would be landscaped with implementation of the proposed project. Therefore, no further analysis is necessary. f) The project site and surrounding area does not lie within or adjacent to an adopted Habitat Conservation Plan, Natural Community Conservation Plan or other approved local, regional, or state habitat conservation plan. Accordingly, there would be no impact to these resource areas.

Potentially Significant Potentially Unless Less than Significant Mitigation Significant No Issues: Impact Incorporated Impact Impact Source V. CULTURAL RESOURCES – Would the project: a) Cause a substantial adverse change in the 1, 23 significance of a historical resource as defined in code 15064.5? b) Cause a substantial adverse change in the 7 significance of an archaeological resource pursuant to 15064.5? c) Directly or indirectly destroy a unique 8 paleontological resource or site or unique geologic feature? d) Disturb any human remains, including those 7 interred outside formal cemeteries?

Discussion

a) As described above, the project site is currently owned by Kaiser and is occupied by the former Albertson’s supermarkets distribution and maintenance center and various warehouse distribution and industrial uses. However, Kaiser has submitted a separate application to the City of San Leandro for the demolition and grading of all structures on the Kaiser site. Therefore, for the purposes of this analysis, it is assumed that the Kaiser portion of the project site will be cleared of structures and rough graded prior to or concurrently with the approval of the project. It should be noted that prior to the granting of the demolition permits for the Kaiser portion of the project site, an assessment of potential historic resources on the project site was undertaken. The assessment determined that the project site did not contain any significant historic resources. Therefore, implementation of the proposed project would have no impact on the significance of a historic resource. b, d) A records search of historic and archaeological resources for the proposed project was conducted on November 30, 2007 at the Northwest Information Center (NWIC) at Sonoma State University. According to the NWIC, the project vicinity contains no recorded Native American or historic archaeological resources listed with the Historical Resources Information System. Based on an evaluation of the environmental setting and features associated with known sites, Native American cultural resources in this part of Alameda County are found in many areas adjacent to water resources like the bayshore or intermittent and perennial watercourses. The proposed project area is on a broad alluvial plain that is marginal to the bayshore. For this reason it is unlikely that unrecorded Native American cultural resources exist in the project area.

Although the project site does not contain recorded Native American or historic-period archeological resources, there remains a low possibility of encountering Native American and cultural archaeological or human remains. Construction activities could result in ground disturbance that would cause a substantially adverse change in the significance of an unknown archeological resource. Thus, impacts are considered potentially significant.

Mitigation Measure. Implementation of Mitigation Measure CR-1 would reduce potential impacts to unknown cultural resources and human remains to a less-than-significant level.

Kaiser Permanente San Leandro Medical Center/Marina Point Mixed-use Development Project Initial Study Page 10 P:\Projects - All Employees\D40000.00+\D41268.00 ICI San Leandro\Initial Study\Kaiser San Leandro Medical Center-Marina Point IS.DOC CR-1. Conduct protocol and procedures for encountering cultural resources. The following provisions shall be incorporated into the grading and construction contracts to address the potential to encounter currently unknown cultural resources:

1. Prior to the initiation of construction or ground-disturbing activities, all construction personnel shall receive environmental training that will include discussion of the possibility of buried cultural and paleontological resources, including training to recognize such possible buried cultural resources, as well as the procedures to follow if such cultural resources are encountered.

2. If potential historical or unique archaeological resources are discovered during construction, all work in the immediate vicinity shall be suspended and alteration of the materials and their context shall be avoided pending site investigation by a qualified archaeological or cultural resources consultant retained by the project sponsors. The immediate vicinity wherein work shall be suspended shall be approximately 50 feet from the discovery or within an appropriate distance to be determined by the archaeologist or cultural resources consultant. Construction work shall not commence again until the archaeological or cultural resources consultant has been given an opportunity to examine the findings, assess their significance, and offer proposals for any additional exploratory measures deemed necessary for the further evaluation of and/or mitigation of adverse impacts to any potential historical resources or unique archaeological resources that have been encountered.

3. If the find is determined to be an historical or unique archaeological resource, and if avoidance of the resource would not be feasible, the archaeological or cultural resources consultant shall prepare a plan for the methodical excavation of those portions of the site that would be adversely affected. The plan shall be designed to result in the extraction of sufficient volumes of non-redundant archaeological data to address important regional research considerations. The work shall be performed by the archaeological or cultural resources consultant, and shall result in detailed technical reports. Such reports shall be submitted to the California Historical Resources Regional Information Center. Construction in the vicinity of the find shall be accomplished in accordance with current professional standards and shall not recommence until this work is completed.

4. The project sponsors shall assure that project personnel are informed that collecting significant historical or unique archaeological resources discovered during development of the project is prohibited by law. Prehistoric or Native American resources can include chert or obsidian flakes, projectile points, mortars, and pestles; and dark friable soil containing shell and bone dietary debris, heat-affected rock, or human burials. Historic resources can include nails, bottles, or other items often found in refuse deposits.

5. If human remains are discovered, there shall be no further excavation or disturbance of the discovery site or any nearby area reasonably suspected to overlie adjacent human remains until the project sponsors have complied with the provisions of State CEQA Guidelines Section 15064.5(e). In general, these provisions require that the County Coroner shall be notified immediately. If the remains are found to be Native American, the County Coroner shall notify the Native American Heritage Commission within 24 hours. The most likely descendant of the deceased Native American shall be notified by the Commission and given the chance to make recommendations for the remains. If the Commission is unable to identify the most likely descendent, or if no recommendations are made within 24 hours, remains may be re-interred with appropriate dignity elsewhere on the property in a location not subject to further subsurface disturbance. If recommendations are made and not accepted, the Native American Heritage Commission will mediate the problem.

Kaiser Permanente San Leandro Medical Center/Marina Point Mixed-use Development Project Initial Study Page 11 P:\Projects - All Employees\D40000.00+\D41268.00 ICI San Leandro\Initial Study\Kaiser San Leandro Medical Center-Marina Point IS.DOC c) Geologically recent invertebrate fossils (mollusks, micro-organisms, etc.) recovered from bay sediments such as those in the project vicinity are widely distributed, are found in predictable locations, and are both abundant and well preserved. Many types of marine and brackish-water invertebrate fossils can number in the millions and can be exposed over many miles of bayside sediments (some invertebrate fossils are so prolific that they constitute major soil or rock material, such as diatomaceous clay or fossiliferous limestone). Consequently, exposed sediments containing abundant, well- preserved, and extensively-distributed invertebrates such as the mollusks in the project vicinity, but lacking vertebrate fossils (see below), are less paleontologically sensitive than limited exposures containing few fossils from a restricted depositional zone.

Vertebrate fossil (fossils representing animals with backbones, including mammals, birds, reptiles, amphibians and fish) are more rare than invertebrate fossils and often are more poorly preserved. In marine sediments, significant vertebrate fossils are much less common than invertebrate fossils. Paleontological resource localities yielding vertebrate fossils frequently represent terrestrial environments, i.e., non-marine deposits such as the Holocene basin deposits at the project site. These continental deposits generally are less uniform depositionally and represent higher energy environments than marine deposits, and, consequently, fossilization is even more infrequent. Further, in life vertebrates are far less abundant than invertebrates (picture the difference between a herd of hundreds or even thousands of bison versus marine beds containing hundreds of millions of bivalves). The infrequency of fossilization and the vicissitudes of the many burial factors involved result in vertebrate fossils being extremely rare relative to their original numbers in life. For these reasons, vertebrate fossil resources are considered to have very high paleontological significance; geologic formations that have the potential to yield vertebrate fossil remains are considered to have the greatest paleontological significance and the highest paleontological sensitivity. Although there are numerous vertebrate-fossil- bearing localities in Alameda County, there are no geological formations of this type in the vicinity of the project site. Therefore, it is extremely unlikely that any paleontological resources exist at the project site.

Seismic-related ground failure, 12, 13, including liquefaction? 14 iv. Landslides? 12 b) Result in substantial soil erosion or the 13, 14 loss of topsoil? c) Be located on a geologic unit or soil that is 13, 14 unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? d) Be located on expansive soil, as defined in 13, 14, Table 18-1-A of the California Building 15 Code (2001), creating substantial risks to life or property? e) Have soils incapable of adequately 1 supporting the use of septic tanks or alternative wastewater disposal systems where sewers are not available for the disposal of wastewater?

Discussion a) i. The project site is not on or immediately adjacent to an active or potentially active fault, nor is it in an Alquist-Priolo Earthquake Fault Zone. The Alquist-Priolo Earthquake Fault Zoning Act requires the delineation of zones along sufficiently active and well-defined faults by the California Department of Conservation, Geological Survey (CGS). The active faults nearest to the project site are the Hayward fault, about 2.5 miles northeast; the San Andreas fault, about 17 miles southwest; the San Gregorio fault, about 25 miles southwest; and the Calaveras fault, about 14 miles northeast. Because the project site is not adjacent to any known active fault nor in an Alquist-Priolo Earthquake Fault Zone, fault rupture hazards would have no impact on the proposed project. a) ii, iii. Alameda County and the San Francisco Bay Area are in one of the most seismically-active regions in the United States. Recent studies by the United States Geological Survey (USGS) indicate there is a 63 percent likelihood of a Moment Magnitude 6.7 (Mw 6.7) or higher earthquake occurring in the Bay Area in the next 30 years. The Hayward fault has the highest probability (27 percent) of generating a Mw 6.7+ earthquake in this timeframe; the probability for the San Andreas fault is 21 percent. The project site could experience very strong (Modified Mercalli Index [MMI] VIII) to violent (MMI IX) groundshaking intensities during a characteristic earthquake on the Hayward or San Andreas Fault. Groundshaking of this intensity could result in moderate damage, such as collapsing chimneys and falling plaster. Seismic shaking of this intensity can trigger ground failures such as liquefaction, potentially resulting in foundation damage, disruption of utility service and roadway damage.

The project site has been identified by the State Geologist as an area where groundshaking-related liquefaction may occur. The Seismic Hazards Mapping Act (SHMA) was enacted in 1990 to protect the public from the effects of strong groundshaking, liquefaction, landslides, or other ground failures

Kaiser Permanente San Leandro Medical Center/Marina Point Mixed-use Development Project Initial Study Page 13 P:\Projects - All Employees\D40000.00+\D41268.00 ICI San Leandro\Initial Study\Kaiser San Leandro Medical Center-Marina Point IS.DOC caused by earthquakes. SHMA requires the State Geologist to delineate various seismic hazard zones and requires cities, counties, and other local permitting agencies to regulate certain development projects within these zones. Before a development permit is granted for a site in a Seismic Hazard Zone, a geotechnical investigation must be conducted and appropriate mitigation measures incorporated into the project design. The CGS Special Publication 117, adopted in 1997 by the CGS in accordance with the SHMA, constitutes guidelines for evaluating seismic hazards other than surface faulting, and for recommending mitigation measures as required by Public Resources Code Section 2695(a).

The project site is in California Building Code Seismic Zone 4, as is about 57 percent of the State, and construction at the site would be required to meet the most stringent Building Code standards. Because it is within the 3.1 mile-wide Near-Source Zone of the Hayward fault, Building Code Section 1629, Criteria Selection, requires Near-Source Factors for Seismic Source Type A to be applied to the design of new structures in this Near-Source Zone.

The City of San Leandro has incorporated the 2006 International Building Code into its municipal building code (Title 7, Chapter 7-5).1 The project sponsors would be required to comply with all applicable State and City regulations and standards to address potential geologic impacts associated with the proposed project, including groundshaking and liquefaction. Geotechnical and seismic design criteria must conform to engineering recommendations in accordance with the seismic requirements of the 2007 California Building Code (Title 24) and any amendments adopted in the City’s municipal code. In addition, if the southern portion of the project site is developed for hospital uses, the hospital facility would be subject to the California Health and Safety Code Division 107, Statewide Health Planning and Development Part 7, which regulates the design of hospitals to ensure seismic concerns are addressed. Finally, because the project site is in a liquefaction Seismic Hazard Zone, the project sponsors would be required to comply with the guidelines set by CGS Special Publication 117.

The San Leandro Building Code requires that all foundations and other improvements (i.e., roads, driveways, utilities) be designed by a licensed professional engineer based on site-specific soil investigations performed by a California Certified Engineering Geologist or Geotechnical Engineer to ensure the suitability (especially considering the existence of potentially liquefiable soils and expansive soils at the site) of the subsurface materials for adequately supporting the proposed structures. All recommendations from the investigation would be summarized in a geotechnical engineering report and incorporated in the project, pursuant to State law. The San Leandro Building Code requires that geotechnical investigations provide design criteria that would minimize impacts associated with strong groundshaking during an earthquake. All structures, roads, and utility lines must meet or exceed design criteria of the 2007 California Building Code. Adherence to the soil and foundation support parameters in Chapters 16 and 18 of the Building Code and the grading requirements in Chapters 18 and A33 of the California Building Code, as required by City and State law, ensures the maximum practicable protection available from soil failures under static or dynamic conditions for structures and their associated trenches, temporary slopes, and foundations. Consequently, the proposed project would have a less-than-significant impact with regard to exposure of people or structures to damage resulting from seismic groundshaking or ground failure. a) iv. The project site is on an alluvial plain with a very slight slope (<2%) from east to west. There are no adjacent hillsides. Consequently, the proposed project would create no impact associated with landslides, mudflows, or other statically or dynamically induced mass soil movements. b) The proposed project would involve grading and trenching, which could create a significant effect on water quality as a result of erosion. Because the project site exceeds one acre in size, the project sponsors would be required to apply for coverage under the State General Construction Permit in order to comply with federal National Pollutant Discharge Elimination System (NPDES) requirements, in

1 Effective January 1, 2008, the City of San Leandro adopted the 2006 International Building Code with amendments.

Kaiser Permanente San Leandro Medical Center/Marina Point Mixed-use Development Project Initial Study Page 14 P:\Projects - All Employees\D40000.00+\D41268.00 ICI San Leandro\Initial Study\Kaiser San Leandro Medical Center-Marina Point IS.DOC accordance with the State Water Resources Control Board requirements (see Section VIII, Hydrology and Water Quality). The project sponsors would be required to develop and implement a Storm Water Pollution Prevention Plan (SWPPP) to reduce potential erosion and subsequent sedimentation of storm water runoff. This SWPPP would include Best Management Practices (BMPs) to control erosion associated with grading, trenching, and other ground surface-disturbing activities. All construction activities would be required to comply with Chapter 18 of the San Leandro Municipal/Building Code, which regulates excavation activities and the construction of foundations and retaining walls, and San Leandro Grading Ordinance, which regulates grading activities, including drainage and erosion control. Prior to receiving a permit, the project sponsors would be required to submit a grading plan to be approved by the City. Compliance with the NPDES permit process and the California Building Code requirements would minimize the effects from erosion during and after construction. Such compliance would ensure that potential erosion resulting from project construction would have a less-than- significant impact. c, d) Two primary soil types are found at the project site: Danville Silty Clay Loam on the north side of the site, and Clear Lake Clay on the south side. These soils have a moderate-to-high shrink/swell potential (i.e., they are potentially expansive), and are both considered weak soils for building purposes. When weak soils are re-engineered specifically for stability prior to use, these potential effects can be reduced or eliminated. An acceptable degree of soil stability would be achieved for expansive, liquefaction- prone, and compressible soils by the required incorporation of soil treatment programs (replacement, grouting, compaction, drainage control, etc.) in the excavation and construction plans to address site- specific soil conditions. A site-specific evaluation of soil conditions is required by the California Building Code and San Leandro Municipal/Building Code and must contain recommendations for ground preparation and earthwork specific to the site that become an integral part the construction design.

As part of the construction permitting process, the City would require completed reports of soil conditions at each specific construction site to identify potentially unsuitable soil conditions including liquefaction, subsidence, and collapse. The evaluations must be conducted by registered soil professionals. The reports must (a) identify potentially unsuitable soil conditions and (b) contain appropriate recommendations for foundation type and design criteria that conform to the analysis and implementation criteria described in the California Building Code, Chapters 16 and 18, to eliminate inappropriate soil conditions.

Adherence to the soil and foundation support parameters of the San Leandro Municipal/Building Code, as required by City and State law, ensures the maximum practicable protection available from soil failures under static or dynamic conditions for structures and their associated trenches, slopes, and foundations. The project sponsors would be required to incorporate these recommendations into the project design. In view of these circumstances, potential hazards related to unstable geologic or soil units would be reduced to a less-than-significant impact.

e) The proposed project would not include any septic tanks or leach field systems. Development in the area would continue to dispose of wastewater through the existing sanitary sewer system. Consequently, the existence of soils incapable of supporting septic systems would have no impact on the proposed project.

HAZARDS AND HAZARDOUS MATERIALS - Would the project: a) Create a significant hazard to the public or 1 the environment through the routine transport, use, or disposal of hazardous materials? b) Create a significant hazard to the public or 1 the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? c) Emit hazardous emissions or handle 1 hazardous or acutely hazardous materials, substances or waste within one-quarter mile of an existing or proposed school? d) Be located on a site which is included on a 1 list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? e) For a project located within an airport land 1, 2 use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? f) For a project within the vicinity of a private 1, 2 airstrip, would the project resulting in a safety hazard for people residing or working in the project area? g) Impair implementation of or physical 1, 2 interference with an adopted emergency response plan or emergency evacuation plan? h) Expose people or structures to a significant 1, 2 risk of loss, injury or death involving wild land fires, including where wild lands are adjacent to urbanized areas or where residences are intermixed with wild lands?

Discussion

a-d) A Phase I Environmental Site Assessment, has been prepared for the project site to identify the potential for onsite or nearby soil or groundwater contamination. Lincoln Continuation High School is located approximately 0.2 miles west of the project site and is therefore within one-quarter mile of the project site. As a result, the proposed project may expose future construction workers and site

This is considered a potentially significant impact. Potential public health risks will therefore be evaluated further in the EIR. e-f) There are no airports or airstrips in the vicinity of the project site. Oakland International Airport is approximately 2.1 miles northwest of the project site and Hayward Executive Airport is approximately 4.2 miles to the southeast. The project site is within the Oakland International Airport height referral area boundary, as described in the Alameda County Airport Land Use Policy Plan. This boundary extends 20,000 feet from the runway and imposes a height restriction of 1 foot for every 100 feet away from the runway. Project compliance with the Alameda County Airport Land Use Policy Plan will be discussed in the Land Use and Planning section of the EIR to be prepared for the project. g) The project would not alter existing emergency response procedures, nor impose a substantial demand on emergency response personnel. Accordingly, the proposed project would not impair implementation or interfere with emergency response in the project vicinity and therefore have no impact. h) The project site is in an urbanized setting, remote from wildlands. Therefore, safety hazards from wildland fires would have no impact on the proposed project.

Discussion

a.) The project site discharges to an underground storm drainage system that outlets to the Estudillo Canal, an engineered channel, prior to discharge into the Lower San Francisco Bay. The applicable water quality objectives and standards for this water body is listed in the San Francisco Bay Basin Water Quality Control Plan Basin (Basin Plan) prepared by the Regional Water Quality Control Board (RWQCB) in compliance with the federal Clean Water Act (CWA) and the State Porter-Cologne Water Quality Control Act. Additionally, section 303(d) of the CWA requires that the states make a list of waters that are not attaining standards after the technology-based limits are put into place. For waters on this list (and where the USEPA administrator deems they are appropriate), the states are to develop total maximum daily loads or TMDLs. TMDLs are established at the level necessary to implement the applicable water quality standards. The proposed project would be subject to existing TMDLs that are considered protective of water quality.

The City of San Leandro Municipal Code regulates the discharge of stormwater and the potential for pollutant transport to water resources through Title 3: Health and Safety, Chapter 3-15 Storm Water Management and Discharge Control. Chapter 3-15 requires best management practices (BMPs) for new developments and redevelopments and compliance with BMPs where BMP guidelines or requirements have been adopted by any federal, state, regional and/or City agency (Section 3-15-215 – Reduction of Pollutants in Storm Water). Additionally, stormwater dischargers are regulated through Title 7: Maps, Buildings, and Subdivisions, Chapter 1-12 Grading, Excavations and Fills. If a grading permit is required, the project applicants must prepare and implement an erosion and sediment control plan (ESCP) including interim and permanent erosion and sediment control measures, and a pollutant control plan (PCP). Additionally, a grading permit cannot be issued until the project developers have filed the required documentation to the State Water Resources Quality Board and have prepared a

Kaiser Permanente San Leandro Medical Center/Marina Point Mixed-use Development Project Initial Study Page 18 P:\Projects - All Employees\D40000.00+\D41268.00 ICI San Leandro\Initial Study\Kaiser San Leandro Medical Center-Marina Point IS.DOC Storm Water Pollutant Prevention Plan (SWPPP) which has been reviewed and approved by the City Engineer. Furthermore, the City Engineer or their representative must conduct inspections prior to issuing a certificate of occupancy, to ensure that requirements are complied with.

In summary, the proposed project would be subject to existing regulations that are considered protective of water quality. The applicable waste discharge requirements and municipal code requirements include preparation of a SWPPP for construction activities and compliance with the Alameda Countywide Clean Water Program (ACCWP). These permit programs are designed to prevent violation of water quality standards through mitigation and control of pollutant transport in stormwater runoff and infiltrating waters. The City of San Leandro municipal code ensures that permit conditions are met. Consequently, the proposed project would not violate water quality standards or waste discharge requirements and the impacts would be less than significant. b) The project site has historically been covered by impervious surfaces including warehouses and associated infrastructure. Therefore, the existing groundwater recharge potential was minimal. An application has been submitted to the City of San Leandro for the demolition and grading of all structures on the Kaiser site. Therefore, for the purposes of this analysis, it is assumed that the Kaiser portion of the project site will be cleared of structures and rough graded prior to or concurrently with the approval of the project. The proposed project includes the development of mixed commercial, residential, and medical uses. Consequently, the proposed project may have less impervious surfaces than past conditions because the future uses would likely have a landscaping requirement whereas landscaping historically been minimal to nonexistent. Regardless, whether or not more landscaped area is incorporated into the final plans compared to existing conditions, there would be a no-net increase in impervious surfaces and therefore, no impact on potential groundwater recharge.

The majority of water supplies serving the City of San Leandro are obtained from the East Bay Municipal Utilities District (EBMUD). The proposed project would not include development of any groundwater supply wells and would rely on EBMUD water supplies. About 90 percent of EBMUD water supplies are surface water resources from the Mokelumne River system with the rest from runoff from local watersheds to terminal reservoirs, such as Chabot Lake (EBMUD 2005).

EBMUD collaborates with the Alameda County Flood Control and Water Conservation District (ACFCWCD), Alameda County Water District (ACWD), the City of Hayward and the California Department of Water Resources (DWR) to coordinate initial regional groundwater management activities, such as sharing monitoring data from each basin and monitoring performance of projects. The basin is currently not in overdraft condition (EBMUD 2005). Therefore, proposed project impacts on groundwater supplies would be less than significant.

It is anticipated that dewatering of excavated pits and trenches could be necessary during the construction phase of the proposed project because there may be a relatively high water table (5-17 ft below ground surface) (DWR 2007). This would locally and temporarily lower the local aquifer table and reduce aquifer volume. However, no large underground structures are anticipated and dewatering would not be expected to continue following the construction phase. Construction impacts on the local groundwater aquifer would be temporary and less than significant.

With implementation of the proposed project, the total area of paved surfaces could be reduced, although the intensity of development would be increased relative to existing conditions. If so, there would be no reduction in groundwater recharge potential. As there would be no long-term impact of the project on the local groundwater table and as water supplies would not involve local groundwater

Kaiser Permanente San Leandro Medical Center/Marina Point Mixed-use Development Project Initial Study Page 19 P:\Projects - All Employees\D40000.00+\D41268.00 ICI San Leandro\Initial Study\Kaiser San Leandro Medical Center-Marina Point IS.DOC resources, there are no new wells proposed. Local groundwater table impacts would be less than significant. c-f) Construction activities associated with the proposed project would generally alter existing drainage patterns in a manner that could result in substantial erosion or siltation as surfaces are exposed to wind and rain. This potentially significant impact will be fully evaluated in the DEIR. g, h) The project site is not located within a FEMA defined 100-year flood hazard area. Therefore, there would be no impacts of or to the 100-year floodplain. i) The project site is located within the dam failure inundation zone for both the Lake Chabot and New Upper San Leandro Reservoir dams. For existing conditions, land use is limited to commercial/industrial. However, the proposed project includes development of residential land uses within this dam failure inundation zone. This would expose more people to risks associated with dam failure inundation, a potentially significant impact.

The EBMUD East Bay terminal reservoirs, such as Lake Chabot and the New Upper San Leandro Reservoir, function as secondary water sources that store runoff from local watersheds for system use. Lake Chabot, an earthen dam, is about 130 years old and holds more than 3 billion gallons of water. The Upper San Leandro Reservoir was built in 1977 and holds more than 13 billion gallons. Requirements for earthquake and flood safety for the East Bay dams are imposed by the State of California Division of Safety of Dams (DSOD), which routinely inspects dams statewide. DSOD requires that embankments under its jurisdiction are safe to withstand the maximum credible earthquake without an uncontrolled release of reservoir water. In 2003, DSOD requested that EBMUD perform a stability evaluation of the Chabot dam. Studies are still in progress (EBMUD 2005). However, studies conducted by EBMUD have identified the time it would take for water to reach certain regions (Beaver, 2005). If the Upper San Leandro Reservoir were breached, much of its contents would surge into Lake Chabot, overflowing it and flooding highly populated areas downstream in a matter of minutes. At 40 mph, it would take just 13.1 minutes to get from Chabot to Estudillo Avenue near Bancroft Avenue. About five minutes later, the water there would peak at a height of 22 feet. Further west, at the intersection of Davis and Alvarado streets, the water would peak at 15 feet.

The City of San Leandro has developed a Hazards Master Plan to coordinate efforts for mitigating emergency conditions. Regardless, the proposed project would expose additional people to potential risk of dam failure inundation, unless sufficient floodproofing and safety mitigation is available. This would be a potentially significant impact and will be evaluated in the DEIR. j) Tsunamis are large sea waves generated by submarine earthquakes or similar large-scale, short- duration phenomena, such as volcanic eruptions, that can cause considerable damage to low-lying coastal areas. Because the project site is located 20 feet above mean sea level, not along an exterior coast, and over one mile inland from the San Francisco East Bay, it would not be subject to tsunami inundation. Therefore, no impact would result, and no further analysis is required.

Mudflow hazards typically occur where unstable hill slopes are located above gradient, where site soils are unstable and subject to liquefaction, and when substantial rainfall saturates soils causing failure. The project site is in a flat area and not located near steep unstable hill slopes susceptible to mudslides. Therefore, the project site is not expected to be subject to a mudflow risk. No impact would result, and no further analysis is required.

Kaiser Permanente San Leandro Medical Center/Marina Point Mixed-use Development Project Initial Study Page 20 P:\Projects - All Employees\D40000.00+\D41268.00 ICI San Leandro\Initial Study\Kaiser San Leandro Medical Center-Marina Point IS.DOC Seiches are waves caused by large-scale, short-duration oscillation of confined bodies of water (such as reservoirs and lakes) during earthquakes that may damage low-lying adjacent areas, although not as severely as a tsunami. The closest enclosed body of water that could result in earthquake-induced seiche is Lake Chabot, over 2.5 miles upstream of the project site. Furthermore, there have never been any documented impacts from seiches at Lake Chabot. Therefore, the project site is not subject to seiche risk. There would be no impact, and no further analysis is required.

LAND USE AND PLANNING – Would the project: a) Physically divide an established community? 1, 2, 3 b) Conflict with any applicable land use plan, 3 policy, or regulation of any agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? c) Conflict with any applicable habitat 2 conservation plan or natural community conservation plan?

Discussion a) The project site is bound by Fairway Drive to the south, Marina Boulevard to the north, I-880 to the east, and Merced Street to the west. The land uses surrounding the site include commercial and industrial to the north, south, and east along with Lincoln Continuation High School across I-880 to the west. The proposed project would allow for residences, retail, restaurant, medical, and other commercial uses to be developed within the existing industrial uses contained in the project vicinity. These uses would complement rather than divide the established community. Therefore, the proposed project would not disrupt or divide the physical arrangement of the community established by existing uses and no project-impact is anticipated. b) The City of San Leandro General Plan contains various policies pertaining to land use, housing, circulation and transportation, open space and recreation, and noise, which could be applicable to the proposed project. Since the proposed project involves the creation of a new General Plan land use designation and zoning district, the EIR will discuss the consistency of the proposed project with applicable plans and policies, and the effects the proposed project may have on the environmental factors associated with density increases and land use/zoning changes. As a result, the proposed project could conflict with an applicable land use plan, policy, or regulation and therefore have a potentially significant impact. This potential conflict will be discussed in the EIR to be prepared for the project. c) There are no habitat conservation plans or natural community conservation plans in effect within the project area. Accordingly, the proposed project would not conflict within any habitat conservation or natural community conservation plans and therefore have no impact.

X. MINERAL RESOURCES – Would the project? a) Result in the loss of availability of a known 21 mineral resource that would be of value to the region and the residents of the state? b) Result in the loss of availability of a locally - 21 important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan?

Discussion

a-b) The State legislation protecting mineral resource zones is the Surface Mining and Reclamation Act of 1975. Part of the purpose of the act is to classify mineral resources in the State and to transmit the information to local governments which regulate land use in each region of the State. Local governments are responsible for designating lands that contain regionally-significant mineral resources in local general plans to assure resource conservation in areas of intensive competing land uses. The law has resulted in the preparation of Mineral Land Classification Maps delineating Mineral Resource Zones (MRZ) 1 through 4 for aggregate resources (sand, gravel and stone).

The project area is classified by the California Geological Survey as MRZ-1, a Mineral Resource Zone for which there is adequate information to indicate there are no aggregate mineral resources present. Consequently, there would be no impact on mineral resources.

Discussion

a-d) Existing ambient noise in the vicinity of the project is predominantly due to motor vehicle traffic, mainly from vehicles traveling on I-880. The vicinity of the project to Oakland International Airport also influences noise levels in the project area. Existing sensitive receptors in the vicinity of the proposed project area include residences to the east of Merced Street and south of Fairway Drive. Students at John Muir Middle School and Lincoln Continuation High School to the east of the project area are also considered sensitive receptors. The project could also introduce new sensitive receptors into the project site because of the residential and potential medical components of the project.

As described below in Section XV, TRANSPORTATION/TRAFFIC, implementation of the proposed project would result in a direct and indirect increase in residents, employees, and visitors to the project site over current conditions. The increased activity levels at the project site, in addition to traffic and operation of the proposed project, have the potential to increase noise levels in the vicinity of the project. This potential increase could impact both existing sensitive receptors, as well as new potential residents within the project area. Accordingly, the effects of noise and vibration could have a potentially significant impact and the EIR will analyze those effects to determine the potential construction, operational, and traffic-related noise effects of the proposed project on sensitive receptors. e-f) The proposed project is not located within the vicinity of a public airport or private airstrip. Oakland International Airport is located approximately 2.1 miles northwest of the project site. The project site is slightly outside the airport’s general referral area and well outside the designated noise zone. However, the effects of any airport-related noise could be considered a potentially significant impact on new residents and patients due to the residential and potential medical components of the project. These effects will be further discussed in the EIR.

POPULATION AND HOUSING – Would the project: a) Induce substantial population growth in an area, 1, 2 either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? b) Displace substantial numbers of existing 1, 2 housing, necessitating the construction of replacement housing elsewhere? c) Displace substantial numbers of people, 1, 2 necessitating the construction of replacement housing elsewhere?

Discussion

a) The proposed project includes the development of 250 new residential units, which would directly lead to population growth in the area. In addition, the proposed project includes development of up to 400,000 square feet of retail uses and potentially 869,000 square feet of medical uses. As a result, the employment at the project site has the potential to be considerably greater than existing conditions. Furthermore, the project could indirectly affect housing demand because increased employment at the project site could result in additional housing demand in the City and surrounding communities. Therefore, the proposed project could induce substantial population growth and result in a potentially significant impact. Accordingly, the EIR will discuss potential effects of greater employment and housing demand as a result of the proposed project.

b-c) No housing units are located within the project area. The construction of replacement housing is not necessary because the proposed project would not displace any housing units or residents. Therefore, the proposed project would have no impact on the displacement of existing homes.

Discussion

a) Implementation of the proposed project would result in a direct and indirect increase in residents, employees, and visitors to the project site over current conditions. This change may necessitate the acquisition of new or additional equipment and hiring of additional personnel in order to adequately maintain acceptable standards of fire and police protection. In addition, the increase in population may result in the need for increased school facilities to accommodate new students or increased public facilities such as access roads. The increased demand associated with the proposed project may result in the need for new or expanded facilities, which, in turn, could result in a potentially significant impact. Therefore, an EIR-level analysis will be performed to determine any environmental effects as result of the proposed project.

Impacts with regards to parks are discussed in Section XIV of this document.

RECREATION - Would the project: a) Would the project increase the use of existing 1 neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? b) Does the project include recreational facilities 1 or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment?

Discussion

a-b) Because the proposed project could result in greater employment and population at the project site, it is expected that demand for parks and recreational facilities could increase. Depending on the existing use and condition of local parks and related recreational facilities, the proposed project could necessitate the expansion or construction of park related resources which could result in a potentially significant impact. Therefore, the EIR will discuss potential project impacts to parks and recreational facilities in the project site and its vicinity.

TRANSPORTATION/TRAFFIC – Would the project: a) Cause an increase in traffic, which is 1, 2 substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)? b) Exceed, either individually or cumulatively, a 1 level of service standard established by the county congestion/management agency for designated roads or highways? c) Result in a change in air traffic patterns, 1, 2 including either an increase in traffic levels or a change in location that results in substantial safety risks? d) Substantially increase hazards due to a design 1 feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? e) Result in inadequate emergency access? 1 f) Result in inadequate parking capacity? 1 g) Conflict with adopted policies, plans, or 1 programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)?

Discussion

a, b, d, f, g) Implementation of the proposed project would result in a direct and indirect increase in residents, employees, and visitors to the project site over current conditions. As a result, the number of project-related trips would be expected to increase demand on the local and regional transportation network and could adversely impact emergency access as a result. The additional traffic could add to congestion at local intersections and could exceed established levels of service. Accordingly, the EIR will examine the transportation impacts of the proposed project on the existing and planned road network, pedestrian and bicycle activity, transit services, parking, and operational safety.

The EIR will analyze potential impacts to the following intersections in accordance with the City’s Transportation Impact Analysis Guidelines: 1. Davis Street/Doolittle Drive 2. Davis Street/Phillips Lane 3. Davis Street/Warden Avenue 4. Davis Street/Southbound I-880 Ramps

c) The proposed project would involve the redevelopment of an industrial site. No aircraft use is required for operation or construction of the proposed facilities. As such, the proposed project would not lead to an increase in air traffic and would have no impact on this mode of travel.

Discussion

a-g) Because the proposed project would result in greater employment and population at the project site, it is expected that demand for public utilities would increase. Depending on the existing and planned capacities to be available, the proposed project could necessitate the alteration or construction of water, wastewater, or solid waste facilities resulting in a potentially significant impact. Therefore, the EIR will discuss potential project impacts to utilities and service systems in the project site and its vicinity.

Potentially Significant Potentially Unless Less than Significant Mitigation Significant No Issues: Impact Incorporated Impact Impact Source XVII. MANDATORY FINDINGS OF SIGNIFICANCE – Would the project: a) Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or a wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or pre-history? b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of

Discussion a) As discussed under Section IV, Biological Resources, the project would not likely affect any sensitive species or habitat. However, trees on the site may provide habitat for nesting birds typically found in urban settings. It is unlawful to take, possess, or needlessly destroy the nest or eggs of any bird, per the California Fish and Game Code (Section 3503). Removal of trees currently on the site during nesting season could affect these birds. (Additionally, potential removal of heritage trees would conflict with a local ordinance protecting biological resources.) The project will not affect historical and architectural resources and the potential for discovering pre-historic cultural resources is low. b) Impacts that are individually limited but can be cumulatively considerable include impacts related to air quality, noise, population and housing, public services, traffic, and utilities. A cumulative discussion of those topics will be included in the EIR. c) As discussed in Section III, Air Quality, the proposed project could introduce regional and localized air emissions through construction and long-term operational activities. Section VII, Hazards and Hazardous Materials, notes that a Phase I Environmental Assessment will be conducted to determine whether or not any contaminated groundwater has been identified beneath the project site. Moreover, as explained in Section XI, Noise, the increased activity levels at the project sites, traffic, and operations (relative to existing conditions and existing zoning) have the potential to generate noise that may disturb nearby sensitive receptors. Given these impacts, the project may have environmental effects that will cause substantial adverse effects on human beings, either directly or indirectly, that need to be explored in the EIR.

The CBC is based on the 2006 International Building Code, but contains Additions, Amendments and Repeals that are specific to building conditions and structural requirements in the State of California. City codes are permitted to be more stringent than Title 24, but are required to be no less stringent. Chapter 16 of the CBC deals with General Design Requirements, including (but not limited to) regulations governing seismically resistant construction (Chapter 16, Division IV). Chapter 18 deals with excavations, foundations, retaining walls, and grading, including (but not limited to) requirements for seismically resistant design, foundation investigations, stable cut and fill slopes, and drainage and erosion control. 15.
