CITY COUNCIL AGENDA ITEM NO. 22

Meeting Date: May 23, 2006

Subject/Title: Adopt a resolution certifying and approving the Negative Declaration and adopting the 2006/07-2010/11 Capital Improvement Program

Prepared by: Doug Alessio, Business Services Manager

Submitted by: Pamela Ehler, Director of Finance and Information Systems

RECOMMENDATION
Adopt a resolution certifying and approving the Negative Declaration and adopting the 2006/07-2010/11 Capital Improvement Program (CIP) for the City of Brentwood including roadway, park, sewer, water and other municipal improvements to be constructed during the next five years.

PREVIOUS ACTION
On July 26, 1994, the City Council approved the first five-year CIP. The CIP budget was added to the City’s adopted 1994/95 budget. The City Council also authorized the creation of the CIP Team to plan, design and administer the projects outlined in the CIP report. The CIP Team is also responsible for updating the CIP report and preparing the report annually. The attached CIP report represents the efforts of the CIP Team to present the City Council with the next year’s update.

On April 11, 2006, the City Council held a workshop on the proposed CIP report. As a result of this workshop, the following changes were made to the 2006/07-2010/11 CIP:

Roadway Improvements:

American Avenue Extension – Modified the project description and map to reflect a change in the scope of the project. The project addresses only the work done at the intersection of American Avenue and Balfour Road. It no longer includes the extension of American Avenue from the existing end along Heritage High School back to Balfour Road.
City Wide Overhead Utility Replacement – This project was submitted with $73k funded by the General Fund, $500k funded by PG&E Rule 20A and $150k unfunded. The following changes were made to ensure the entire project was funded: removed $3k in Project Administration from Prior; reduced Planning and Design in 06/07 $30k, from $80k to $50k; reduced Construction in 07/08 by $120k, from $570k to $450k; reduced Project Administration in 07/08 by $20k, from $50k to $30k; moved all 06/07 dollars to 07/08 and moved all 07/08 dollars to 08/09. These changes resulted in a $23k decrease in the amount of funds required from the General Fund.
Grant Street Undercrossing – This project was removed from the Capital Improvement Program.
Lone Tree Way – Union Pacific Undercrossing – The following changes were made due to the uncertainty of the negotiations with the Union Pacific Railroad: moved $450k in Planning and Design from Prior, $350k to 06/07 and $100k to 09/10; reduced Construction in 06/07 by $140k, from $1.3M to $1.16M; moved $3M in Construction from 07/08 to 10/11 and moved all 07/08 dollars to 08/09; moved $460k in Project Administration from 08/09 to 10/11 and moved all 08/09 dollars to 09/10. Additionally, the project is unfunded in 08/09, 09/10 and 10/11 except for $644,230 in Development Contributions in 08/09.

Parks and Recreation Improvements:

Minnesota Avenue / Central Boulevard Soundwall – This project was removed from the Capital Improvement Program.

Development Improvements:

Fairview Avenue Improvements – Phase VIII – This project was removed from the Capital Improvement Program.

On May 9, 2006, the City Council approved the report and referred it to the Planning Commission for a consideration of conformance to the City’s General Plan.

On May 16, 2006, the Planning Commission found the 2006/07-2010/11 CIP to be consistent with the City of Brentwood General Plan and recommended that the City Council certify the Negative Declaration. The Planning Commission also recommended City Council ensure sufficient funds are allocated for shade trees and shade facilities in the City’s parks. Pursuant to this recommendation, staff contacted the Director of Parks and Recreation who stated the Parks and Recreation Commission currently requires all park designs include shade trees and shade structures as a condition of approval.

A copy of the CIP is available for public review in the City Clerk’s office, Engineering Department lobby, Community Development lobby, Parks and Recreation lobby and at the Brentwood library.

BACKGROUND
Adoption of the 2006/07-2010/11 CIP will continue the five-year Capital Improvement Program for City projects. An annual update will take place in the year 2007 and every subsequent year. The preparation of this annual budget assists staff in determining and updating our development fee program that finances the majority of these projects.

A Negative Declaration has been prepared to address the potential environmental effects of the CIP. The Negative Declaration finds that no significant adverse impacts would result should this program be adopted. Therefore, staff recommends that the City Council certify the Negative Declaration and file a Notice of Determination with the County Clerk.

FISCAL IMPACT
The fiscal year 2006/07 costs from various non-General Fund sources are noted in the CIP. Future year costs and revenues will be reviewed every year by the City Council as a part of the annual update and adoption of a new five-year CIP.

Environmental Checklist/
Initial Study

Introduction
This Initial Study has been prepared in accord with the provisions of the California Environmental Quality Act (CEQA) and assesses the potential environmental impacts of implementing the proposed project described below. The Initial Study consists of a completed environmental checklist and a brief explanation of the environmental topics addressed in the checklist.

Project Location and Context
Brentwood is located in eastern Contra Costa County on the eastern perimeter of the San Francisco Bay metropolitan complex. The City is approximately equidistant (fifty miles) from San Francisco to the west and Sacramento to the east.

The Brentwood planning area encompasses approximately 30 square miles with the boundaries formed by the City of Antioch to the west and northwest, Oakley to the north and unincorporated agricultural lands to the south and east.

Exhibit 1 shows the Brentwood's location with respect to the Bay Area.

Project Description
The proposed project is the City’s Capital Improvement Program (CIP) for fiscal years 2006-2007 to 2010-2011, which inventories proposed capital improvements throughout the City over a five-year period. Preliminary budgets are also provided for individual projects identified in the CIP. Capital improvements include a range of public works and infrastructure projects to enhance the quality of life for local residents and visitors. Proposed projects include roadway, parks and trails, water, wastewater, drainage, community facility improvements and developer-funded improvements throughout the City of Brentwood.

The document is submitted to the City Council for adoption in conjunction with the 2006-2007 budget process. Major capital improvements can take several years to plan, design, finance, and construct. As noted in the Capital Improvement Program document, the purposes of a five-year program are to:

_•* Ensure that planning for capital improvements is tied to realistic, predictable sources of income.

_• Define desired improvements and construction schedules so that there is adequate time for pre-planning, environmental review, planning, design, and community/Council review.

_• Establish basis for future maintenance projections.

_• Integrate the Capital Improvement Program with other activities, such as the City’s General Plan.

The CIP is developed as a coordinated effort between the CIP Project Managers and the CIP Executive Committee. The CIP Project Managers submit projects to the Executive Committee based on perceived need and feasibility of the project. The CIP Executive Committee, made up of the City Manager, the City Engineer and the Director of Finance, evaluate the projects based on need and available funding. Some projects have specified funding sources, such as assessment districts or special fees and are, for the most part, recommended for funding without question. However, some projects may compete for limited fund dollars. These projects are prioritized by the Executive Committee. The list is then compared to available staffing and dollars and as many projects as feasibly possible are funded, either fully or partially, with any remaining projects designated as unfunded.

All submitted projects, whether funded or unfunded, are included in the CIP and recommended to the City Council for approval. City Council and citizen input on the proposed CIP is solicited by way of the CIP Workshop. The CIP document is then reviewed by the Planning Commission for determination of General Plan conformance. Finally, the draft document is presented to the City Council for review and public input prior to the City Council’s final approval.

The CIP Executive Committee also manages the CIP on an ongoing basis throughout the fiscal year, providing progress reports to the Council, evaluating new opportunities and resolving issues.

The CIP contains individual projects within the following general categories:

1) Roadway improvements, including purchase of land for new roads and improvements to existing roads, such as road widenings, construction and/or realignment of roads, installation of and/or upgrades to traffic signals, sidewalk replacement, acoustic wall construction, repaving and overlay of streets, roadway grade crossings, bridge crossings over creeks and related actions, including traffic calming. Major roadway improvements envisioned in the CIP include but are not limited to extension of American Avenue, the extension of John Muir Parkway, the extension of Logan Way and Lone Tree Way widening.

2) Parks and Trail improvements including purchase of land for new parks, development of new parks and improvements to existing parks, public art programs, creek enhancements, and development of recreational trails within the community. A number of these proposed improvements include but are not limited to development of Blackhawk Park, a joint use theater with the school district, City park redesign, Sand Creek Park soccer fields construction, John Marsh Home rehabilitation, a joint-use gymnasium, Windsor Park expansion and similar facilities.

3) Water improvements, including purchase of land for new and upgraded water lines, construction and upgrading of water reservoirs, water well upgrading, a well monitoring program, a surface water treatment facility, rehabilitation of existing water lines, water treatment facilities, and similar facilities intended to improve the delivery of water and water pressure and to ensure drinking water quality standards continue to be achieved. Specific major water projects include a new surface water treatment facility, construction of well #15, and a new reservoir for the zone 1 water pressure system.

4) Wastewater improvements, including new and upgraded sewer collectors, development of a recycled water program to reduce the need for potable water, and expansion and upgrades of the City’s wastewater treatment plant.

5) Community facilities improvements, including new and upgraded public buildings and City facilities, such as a new City Hall, a downtown parking structure, two new fire stations, a geographic information system (GIS) mapping program, a fiber optic installation, improvements to the City’s solid waste transfer station, upgrades to the City’s information technology, upgrades to the Community Center and Maintenance Service Center and similar facilities.

6) Drainage improvements, including a program to mitigate agricultural water runoff and storm drain improvements.

7) Developer improvements consist primarily of road, water, sewer and drainage and similar improvements that are anticipated to be made by private developers and dedicated to the City.

Table 1 presents a summary of the City’s proposed projects by CIP category. It is possible that minor changes may be made to this list as it is reviewed by the City staff and Brentwood City Council, however, this is substantially the list of projects envisioned to be undertaken within the five-year time frame. A more complete description of these proposed projects is available at the City of Brentwood Engineering Department, 120 Oak Street, Brentwood, during normal business hours.

It is important to note that Council approval of the five-year CIP does not constitute an appropriation of funds to the specific project(s). Projects are funded as a result of budget approval or specific allocation of funds by the City Council. In addition, some projects may proceed as a result of grant approval of funding from other sources (developer, county, state or federal source).

Additional environmental review, if required, would occur for individual projects contained within the CIP, as more specific information is provided through specific design processes and individual project initiation by the City.

Environmental Factors Potentially Affected
The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a "potentially significant impact" as indicated by the checklist on the following pages.

- Aesthetics
- Agricultural Resources - Air Quality
- Biological Resources
- Cultural Resources - Geology/Soils
- Hazards and Hazardous Materials
- Hydrology/Water Quality - Land Use/Planning
- Mineral Resources
- Noise - Population/Housing
- Public Services - Recreation
- Transportation/
Circulation
- Utilities/Service Systems - Mandatory Findings of Significance

Determination (to be completed by Lead Agency):

On the basis of this initial evaluation:

___ I find that the proposed project could not have a significant effect on the environment and a Negative Declaration will be prepared.

X_ I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A Negative Declaration will be prepared.

____ I find that although the proposed project may have a significant effect on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on earlier analysis as described on the attached sheets, if the effect is a "potentially significant impact" or "potentially significant unless mitigated." An Environmental Impact Report is required, but must only analyze the effects that remain to be addressed.

___ I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier EIR pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR, including revisions or mitigation measures that are imposed on the proposed project.

Evaluation of Environmental Impacts

1) A brief explanation is required for all answers except "no impact" answers that are adequately supported by the information sources a lead agency cites in the parenthesis following each question. A "no impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g. the project falls outside a fault rupture zone). A "no impact" answer should be explained where it is based on project-specific factors as well as general factors (e.g. the project will not expose sensitive receptors to pollutants, based on a project-specific screening analysis).

2) All answers must take account of the whole action, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts.

3) "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significant. If there are one or more "potentially significant impact" entries when the determination is made, an EIR is required.

4) "Negative Declaration: Potentially Significant Unless Mitigation Incorporated" implies elsewhere the incorporation of mitigation measures has reduced an effect from "potentially significant effect" to a "less than significant impact." The lead agency must describe the mitigation measures and briefly explain how they reduce the effect to a less than significant level.

1. Aesthetics

Environmental Setting
Brentwood is located in the eastern valley area of Contra Costa County immediately east of the Diablo Range. The City has historically been surrounded by agricultural uses, including row crops, orchards and grazing.

Major scenic resources include riparian corridors that traverse the community and distant views of Mt. Diablo and other foothills.

Project Impacts
a-c) Have a substantial adverse impact on a scenic vista? LS. Roadway improvements and parks and trails improvements would increase access to scenic vistas and would, therefore, have a beneficial impact. Proposed water and wastewater projects consist of improvements to existing infrastructure (e.g., waterline replacements, new water well, well monitoring program, well abandonment) would typically be underground facilities so that no impacts would relate to scenic resources. Proposed construction of the Zone I reservoir and other above ground facilities would be subject to further environmental documentation to review potential impacts to aesthetics.

Major community facilities improvements include new City parks, a new City Hall, new fire stations, a downtown parking structure and other projects would be subject to design review by the Brentwood Planning Commission to ensure that less-than-significant impacts would be created with regard to scenic vistas. Other community facility projects would have no aesthetic impacts, including but not limited to fiber optic links, the GIS system, and ADA improvements

d) Create light or glare? LS. Roadways improvements, community facilities and parks may include new sources of light, including street lighting, playfield lighting and security lighting. The potential for new sources of light and glare and potential impacts surrounding properties will be evaluated as part of future review of specific CIP projects and mitigation measures determined, if necessary. The majority of projects include minor additions to existing facilities or underground utility lines, so less-than-significant impacts are anticipated and no mitigation measures are required at this level of environmental review.

2. Agricultural Resources

Environmental Setting
Brentwood and the eastern Contra Costa County area contain a significant amount of the County's prime agricultural land. Among its advantages is the availability of relatively low cost irrigation water, a superior growing climate, presence of prime soils and, until the last few years, the absence of strong urbanization pressure.

Urbanization of agricultural soils was considered a significant and irreversible impact in the General Plan EIR and a Statement of Overriding Considerations was adopted as part the Certification of the 1993 General Plan EIR. Approximately four years ago, the City of Brentwood adopted an Agricultural Enterprise Program to protect existing prime agricultural operations.

Large specific projects included in the 2006/07-10/11 CIP may be required to provide some level of mitigation for loss of prime agricultural soils depending on their location. These will be evaluated at the time specific CIP projects may be initiated.

Project Impacts
a-c) Convert Prime Farmland, conflict with agricultural zoning or convert prime farmland to a non-agricultural use? LS. Many of the projects proposed as part of the CIP would have no impact on agricultural lands or agricultural resources. These would be water and sewer projects, minor roadway improvements, improvements to existing City parks, downtown improvements and civic improvements. Some of the proposed projects, including the proposed new City Hall, new fire stations, new roads, new parks and similar facilities may convert small amounts of existing farmland to non-agricultural uses, however, such increases would be subject to providing mitigation pursuant to the City’s Agricultural Enterprise Program. Therefore, conversion of prime agricultural lands associated with the implementation of several proposed CIP projects are anticipated to be less-than-significant. Additional environmental reviews will be conducted by the City of Brentwood for individual projects that could have the possibility of impacting agricultural uses or prime farmland.

One of the proposed CIP projects would mitigate stormwater runoff from agricultural operations in the community, which would be a beneficial impact and would assist in supporting on-going agricultural operations in the community.

3. Air Quality

Environmental Setting
The project area is located on the southern shore of the San Joaquin River delta, east of the Carquinez Strait. This geographic portion of Contra Costa County is typified by winds flowing through the Carquinez Strait and into the Delta.

Air quality emissions within Contra Costa County is regulated on the federal level by the Environmental Protection Agency (EPA), on the state level by the California Air Resources Board (CARB) and on a regional and local level by the Bay Area Air Quality Management District (BAAQMD). Federal and state air emission standards have been established for the following substances: carbon monoxide, ozone, particulate matter (PM-10), nitrogen dioxide, sulfur dioxide and lead.

The BAAQMD maintains monitoring stations at Concord, Pittsburg and Bethel Island within Contra Costa County. As indicated in the General Plan EIR, there were minimal exceedances of state and federal air quality standards through 1990 for ozone and carbon monoxide.

Project Impacts
a) Would the project conflict or obstruct implementation of an air quality plan? NI. Would the project conflict or obstruct implementation of an air quality plan? NI. None of the proposed projects would serve to impede the implementation of any local, regional, state or federal air quality. No impacts are therefore anticipated. Proposed trail projects would serve to provide an alternative to automobile travel and could have a beneficial air quality impact. Similarly, landscape improvements associated with the Community Beautification project, Tree Reforestation project and planting of trees and other vegetation at Blackhawk Park, Empire Elementary School/Park, Sand Creek Parks and other parks would serve to filter out air pollutants, such as carbon monoxide.

b) Would the project violate any air quality standards? LS. Construction of roadway improvements, developer improvements (many of which are developer-funded roadway improvements, as shown in Table 1), new public buildings and parks may violate air quality standards or contribute to a projected air quality violation. Two potential air quality impacts are identified in this Initial Study: short-term construction air quality impacts and long-term operational air quality impacts.

Short-term construction impacts
Construction activities such as earthmoving, excavation and grading operations, construction vehicle traffic and wind blowing over exposed earth would generate exhaust emissions and fugitive particulate matter emissions that would affect local and regional air quality. These activities would generate exhaust emissions and fugitive particulate matter emissions that would affect local and regional air quality. Construction activities are also a source of organic gas emissions. Solvents in materials would evaporate into the atmosphere and would participate in photochemical reaction that creates urban ozone. Asphalt used in paving is also a source of organic gases for a short time after application.

Construction dust could affect local air quality at various times during construction of the proposed projects. The dry, windy climate of the area during the summer months creates a high potential for dust generation when and if underlying soils are exposed to the atmosphere.

The effects of construction activities would be increased dustfall and locally elevated levels of PM10 downwind of construction activity. Construction dust has the potential for creating a nuisance at nearby properties. These potential impacts would be mitigated on a project-by-project basis by requiring mitigation measures controlling dust generation.

Long-term operational impacts
On the local scale, roadway projects would change traffic on the local street network, changing carbon dioxide levels along roadways used by project traffic. Carbon monoxide is an odorless, colorless poisonous gas whose primary source in the Bay Area is automobiles. Concentrations of this gas are highest near intersections of major roads.

Project-related emissions from vehicles are expected to be below thresholds of significance from major pollutants, since the amount of traffic is consistent with regional transportation projections. Therefore, operational air quality impacts are expected to be less-than-significant.

c) Would the project result in cumulatively considerable air pollutants? NI. Many if not all of the proposed projects listed in the CIP would assist in supporting development anticipated in the Brentwood General Plan. Many of the air quality impacts associated with the General Plan can be mitigated to a less-than-significant level through goals and policies contained in the General Plan as well as through adherence with local zoning requirements and other development requirements, such as the State Building Code and Brentwood Zoning Ordinance. For long-term regional air pollutants, the General Plan EIR notes these would be significant and unmitigatable, so a Statement of Overriding Considerations was adopted and no further analysis is required.

d,e) Expose sensitive receptors to significant pollutant concentrations or create objectionable odors? NI. Projects envisioned as part of the CIP primarily involve utility infrastructure and community projects. No residential development is anticipated as a result of implementing proposed CIP projects. Therefore, no impacts regarding creation of odors or introducing significant pollutants to sensitive receptors are anticipated.

4. Biological Resources

Environmental Setting
Brentwood lies in the western portion of the San Joaquin Valley, immediately east of the Mt. Diablo Range. The majority of soils within the planning area are formed from alluvial sediment from nearby hills and are moderately well drained with slow runoff.

A series of east-west trending ridges and valleys extend eastward from the Mt. Diablo Range toward the San Joaquin Valley. Lone Tree, Horse Valley, Deer Valley and Briones Valley for a set of drainage basins which collect seasonal rainwater and direct runoff into a network of small streams and creeks in the Brentwood area, including Marsh Creek, Sand Creek, Deer Creek and Dry Creek.

Vegetation types in and near Brentwood include urban, rural/agricultural, grassland/oak savanna, vernal pool, riparian, fresh emergent wetland and alkali sink. Each of these vegetation types have associations of animal, reptile and bird species within them.

Project Impacts
a) Have a substantial adverse impact on a candidate, sensitive, or special-status species? LS. The majority of projects proposed in the CIP are relatively minor and would be located in an urbanized area. A number of projects, primarily new roads, trails, new parks, new drainage facilities and the proposed Creek Habitat Enhancement Program, could have impacts to wetland or upland special-status species of plants or wildlife. New and extended roadways and water lines, depending on their locations, may impact wetland resources. Similarly, drainage improvements may increase flows into existing channels. Impacts to biological resources from these projects will be evaluated at the time specific projects are proposed to be implemented. Projects proposed on non-wetland upland areas of the City could also impact burrowing owl species or their habitats. Potential impacts to special-status plants and wildlife and their respective habitat will be evaluated at the time individual projects are proposed and appropriate environmental reviews conducted prior to individual project approval. Overall, impacts to sensitive biological species at this program level are anticipated to be less-than-significant.

b, c) Have a substantial adverse impact on riparian habitat or federally protected wetlands? LS. The General Plan EIR notes that four creeks traverse the Planning Area – Sand, Deer, and Dry Creeks flow into the major water course, Marsh Creek. Some of the proposed facilities may be located close to a creek; the proposed roadway improvements may traverse one or more creeks. Each proposed CIP project will be subject to its own Initial Study pursuant to CEQA and possible further environmental review. At that time, with more specific information about the proposed project, impacts will be identified and appropriate mitigation measures will be proposed. Less-than-significant impacts are anticipated at this program level of review.

d) Interfere with movement of native fish or wildlife species? LS. Consideration of impacts, if any, of proposed projects with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or with the impeded use of native wildlife nursery sites will occur on a project-by-project basis. Each project will be subject to its own Initial Study, if applicable. At that time, with more specific information about the proposed project, impacts will be identified and appropriate mitigation measures will be proposed. Overall, less-than-significant impacts are anticipated with regard to movement of fish or wildlife species at this program level of review.

e, f) Conflict with local policies or ordinances protecting biological resources or any adopted Habitat Conservation Plans or Natural Community Conservation Plans? NI. The City is located within the boundaries of the Eastern Contra Costa Habitat Conservation Plan and is a participant in this multi-agency planning effort. No impact is anticipated at this time, since a final plan has not been adopted, however, any future capital projects that may occur within the planning area of the HCP will be required to be reviewed to determine consistency with HCP elements.

5. Cultural Resources

Environmental Setting
Information presented in the General Plan EIR notes that the Brentwood Planning Area was historically occupied by indigenous Indian tribes, including the Mi-Wok and Ohlone. Based upon a number of site specific studies conducted in the area, the EIR concludes that Brentwood has a low to moderate probability of containing prehistoric artifacts and a moderate to high probability of containing historic resources.

Project Impacts
a-d) Cause substantial adverse change to significant historic resources? LS. A number of projects listed in Table 1 could have impacts to historic, archeological, cultural, Native American, paleontological resources since they would involve sub-surface excavation (such as roadways and utility lines). Other CIP projects would involve upgrades to historic structures, such as the John Marsh House. A number of these proposed projects could impact sensitive cultural resources. The possible impact of a proposed CIP project on such resources will be addressed on a project-by-project basis as individual projects are proposed for implementation. At that time, possible impacts will be assessed and appropriate mitigation measures proposed based on CEQA standards. Overall, since many of the projects identified in the CIP are minor, less-than-significant impacts are assumed.

6. Geology and Soils

Environmental Setting
Brentwood is located along the northwest margin of the San Joaquin Valley, with Mount Diablo to the west and Suisun Bay and the Sacramento/San Joaquin River Delta to the north. The community borders two geomorphic provinces, the Coast Range Province and the Great Valley Province. The Coast Range Province includes a north-south trending coastal range comprised of marine sediments and volcanic rocks. Once a large inland sea, the Great Valley Province was filled with sediments eroded from nearby mountains with current alluvial deposits laid down on flood plains within river and stream beds.

Soil conditions are generally of a fine-grained nature and comprised of clay, silt and fine-grained sand. Loamy sand and silty clay loam exists in small quantities along stream channels and near sandstone beds in the western and southern portions of the community's planning area.

Being a part of the San Francisco Bay area, Brentwood is subject to seismic activity from a number of local and regional earthquake faults, including the San Andreas fault, located approximately 45 miles west of the city, the Hayward Fault, located approximately 27 miles west, and the Calaveras fault, approximately 18 miles southwest. Other regional faults include the Greenville fault, approximately 25 miles to the southwest and the Concord-Green Valley fault, generally located 14 miles west of Brentwood.

Locally identified seismic faults, which are mapped on Figure 7 of the1993 General Plan EIR, include the Antioch-Davis fault and the Brentwood-Sherman Island Fault, both located west of the project study area.

Project Impacts
a) Expose people or structures to potential substantial adverse impacts, including loss, injury or death related to ground rupture, seismic ground shaking, ground failure, or landslides? LS. The Brentwood planning area is not within the boundaries of an Earthquake Fault Zone. Therefore, the risk of damage due primary fault rupture is determined to be low, although future projects constructed identified in the CIP will be designed to adhere to the most stringent seismic requirements applicable. Major CIP projects will be required to obtain geotechnical analyses per standard City requirements and to follow site-specific construction recommendations. This is considered a less-than-significant impact at this programmatic level.

b) Is the site subject to substantial erosion and/or the loss of topsoil? LS. Certain proposed roadway and trail improvements, proposed park developments, construction of new public buildings and other CIP projects would entail grading, excavation and possibly filling. The amount of material to be graded is not known at this time. Grading is not anticipated to significantly change existing topographic patterns; however, erosion of graded material could result in significant impacts. Unless properly controlled, erosion of earthen material and/or construction debris could impact surface water quality of projects close to creeks. Erosion could also impact adjacent public streets, private property, and the City’s storm drain system. The City will require submittal of an erosion and sedimentation plan prior to commencement of site grading for individual projects to ensure that erosion impacts would be reduced to a less-than-significant level.

c-d) Is the site located on soil that is unstable or expansive or result in potential lateral spreading, liquefaction, landslide or collapse? LS. Individual sites for each project would be examined for the possible occurrence of expansive soils, lateral spreading, liquefaction and related hazards. Adherence to recommendations contained in each soils and geotechnical report would ensure that any expansive soils or similar hazards found on individual sites would be reduced to a level of insignificance. This is a less-than-significant impact and no mitigation measures are required.

e) Have soils incapable of supporting on-site septic tanks if sewers are not available? NI. None of the projects listed in the current CIP document involve use of septic systems Therefore, no impact is anticipated with regard to septic tanks.

7. Hazards and Hazardous Materials

Environmental Setting
The General Plan EIR notes that major sources of hazards in Brentwood include hazards linked to oil extraction operations, chemical pesticides and fertilizers related to historic and on-going agricultural operations, industrial operations and hazardous materials that may be transported on major transportation corridors in the community.

Project Impacts
a-c) Create a significant hazard through transport of hazardous materials or release or emission of hazardous materials? LS. The majority of proposed projects identified in the CIP would not entail the routine transport or disposal of hazardous materials. A small number of proposed projects would include use of potentially hazardous material, such as the proposed well disinfection system and well chlorination. This work would be done in compliance with local, state and federal safety standards and likely subject to additional environmental studies at the time they would be constructed. Less-than-significant impacts would result and no mitigation measures are required.

b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? LS. None of the proposed CIP projects, with the possible exceptions of those related to water and wastewater improvements, involves processes in which accidental releases might occur. Future proposed water and wastewater improvements will be subject to initial study pursuant to CEQA and appropriate subsequent environmental review at the time these projects are initiated. Less-than-significant impacts are therefore anticipated and no mitigation measures are required.

d) Is the site listed as a hazardous materials site? NI. The State of California Department of Toxic Substances Control (DTSC) does not list any sites within the City of Brentwood as containing contaminated soil or groundwater conditions. Therefore, no impacts would result at this programmatic level of review. This information was current as of April 3, 2006.

e,f) Is the site located within an airport land use plan of a public airport or private airstrip? NI. None of the proposed projects are located near a public or private air facility so no impacts are anticipated and no mitigation measures are needed.

g) Interference with an emergency evacuation plan? NI. Proposed roadway improvements included in the CIP can be anticipated to have a beneficial impact by offering responding personnel additional alternative routes through the city. No impacts are anticipated and no mitigation measures are required.

h) Expose people and structures to a significant risk of loss, injury or death involving wildland fires or where residences are intermixed with wildlands? NI. Few the proposed new facilities would be located at the perimeter of the city. Further, most peripheral areas are developed or cultivated to minimize the possibility of wildland fire. Therefore, no impacts would result and no mitigation measures are needed.

8. Hydrology and Water Quality

Environmental Setting
The City of Brentwood lies on the southwestern edge of the Sacramento/San Joaquin River Delta. The primary natural drainage channel in the community is Marsh Creek, which originates in the foothills of Mt. Diablo and flows north through Brentwood to the San Joaquin River.

Project Impacts
a) Violate any water quality standards or waste discharge requirements? LS. None of the proposed projects are anticipated to violate existing standards and requirements. proposed improvements to the wastewater treatment plant would comply with NPDES discharge requirements. Improvements to the City’s municipal water system will ensure that state and federal water standards are met. Therefore, less-than-significant impacts would result and no mitigation measures are required. Proposed surface drainage improvements included in the CIP, including the agricultural runoff mitigation program, would have a beneficial impact. No mitigation measures are required at this programmatic environmental review level.

b) Substantially deplete groundwater recharge areas or lowering of water table? LS. None of the proposed water improvements are anticipated to substantially deplete groundwater supplies. Withdrawals of underground water resources for domestic and firefighting purposes are currently occurring in accord with existing agreements. The proposed CIP budget does include new water wells and well site improvements, all of which will be done in cooperation and with necessary permits from local groundwater authorities. Less-than-significant impacts are anticipated.

c-e) Substantially alter drainage patterns, including streambed courses such that substantial flooding, siltation or erosion would occur? LS. Many of the proposed projects included in the CIP would involve minor additions to existing surface facilities (i.e., installation of traffic signals at existing intersections and sidewalk upgrades), or would be underground facilities, such as water, sewer and/or drainage pipelines. Neither of these types of projects would contribute to flooding or increased stormwater runoff. For larger projects, such as construction of new roads, public buildings, parking lots, parks and similar projects, grading plans would be prepared and reviewed by the City Engineer as part of final construction drawings and specifications to ensure that anticipated runoff will not exceed stormwater drainage system capacity. In addition, construction of proposed drainage facilities would improve existing drainage patterns and result in a beneficial impact. Overall, less-than-significant impacts are anticipated and no mitigation measures are required.

f) Substantially degrade water quality? LS Refer to the analysis and mitigation measure under "a," above.

g, h) Place housing within a 100-year flood hazard area as mapped by a Flood Insurance Rate Map? NI. None of the proposed projects would involve the construction of new housing, so there would be no impacts related to flooding of housing projects and no mitigation measures are needed.

j) Result in inundation by seiche, tsunami or mudflows? NI. The Brentwood planning area is well inland from the San Francisco Bay and other major bodies of water. CIP projects would therefore not be subject to seiche or tsunami. Individual projects in proximity to slopes would be subject to geologic and other environmental review to ensure safety from possible mudflow. No impacts are therefore anticipated and no mitigation measures are needed.

9. Land Use and Planning

Environmental Setting
The City of Brentwood has historically been an agricultural community. Growth pressures in Contra Costa County have resulted in increased residential development in Brentwood and additional residential growth is anticipated in the near future. As the City has matured, commercial development has occurred along with employment uses. Brentwood is recognized as one of the fastest growing communities in California. The General Plan was most recently updated in 2001 and provides for a mix of residential, commercial, industrial, and open space and public uses. Goals and polices are also included in the General Plan to require the provision of adequate infrastructure and community services to support anticipated growth.

Project Impacts
a) Physically divide an established community? LS. The proposed roadway projects included in the CIP comprise the improvement, extension or widening of existing roadways. No other projects listed in the CIP would physically divide an existing community. For these roadway projects, there could be temporary rerouting of local traffic to accommodate construction. Long-term impacts that could physically divide a community would be reviewed in CEQA documents prepared for individual roadway projects. Less-than-significant impacts are therefore anticipated. One of the proposed community facilities projects is to install traffic calming devices in portions of the community to assist in neighborhood cohesion. Other projects included in the Parks and Trails section, development of community trails, would help to integrate the community.

b) Conflict with any applicable land use plan, policy or regulation? NI. The City’s Capital Improvement Program is consistent with General Plan goals, policies and objectives. No impacts would therefore result and no mitigation measures are needed.

c) Conflict with a habitat conservation plan or natural community conservation plan? NI. No such plan has been adopted within the City of Brentwood, although the City is a participant in the development of the Eastern Contra Costa Habitat Conservation Plan. There would therefore be no impact with regard to the plan at this time, since it has not been adopted. Future CIP projects will be reviewed at the time they are proposed to ensure consistency with the HCP.

10. Mineral Resources

Environmental Setting
Primary mineral resources in Brentwood include oil and gas fields in the northwesterly quadrant of the community and sand and coal deposits in the southerly portion of the Brentwood planning area.

Project Impacts
a, b) Result in the loss of availability of regionally or locally significant mineral resources? NI. None of the proposed projects is located in proximity to a resource that would be of value to the region and the residents of the state. Therefore, no impacts would result and no mitigation measures are required.
11. Noise

Environmental Setting
Primary long-term sources of noise in the Brentwood planning area include vehicular noise from major highways and streets, railroad noise, and operational noise generated by industrial uses.

Short-term, periodic, noise is also generated from construction activities.

Project Impacts
a, d) Would the project expose persons or generation of noise levels in excess of standards established by the General Plan or other applicable standard: LS. Construction of roadway improvements, new civic buildings, parks, trails and other facilities identified in the proposed CIP would increase noise levels on properties adjacent to these projects. During environmental review of individual CIP projects, the City can impose appropriate mitigation measures regarding noise abatement and hours of construction to mitigate these impacts to less-than-significant and no mitigation measures are required.

b) Exposure of people to excessive groundborne vibration or groundborne noise levels? NI. None of the proposed projects are industrial activities that would generate groundborne vibration. The municipal water and wastewater operations are buffered from incompatible land uses. Therefore, no impacts would result and no mitigation measures are required.

c, d) Substantial permanent increases in permanent or temporary ambient noise levels? LS. New roadways and well projects included in the proposed CIP could result in a permanent increase in ambient noise levels. The City will review such projects on a case-by-case basis to identify potential noise level increases and impose appropriate mitigation measures, if needed, to reduce impacts to a less-than-significant level. Regarding a temporary or periodic increase in ambient noise levels, the City would impose appropriate mitigation measures regarding noise abatement and hours of construction for major projects to mitigate these impacts to a less than significant level.

e, f) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport, public use airport or private airstrip, would the project expose people residing or working in the project area to excessive noise levels? NI. None of the projects are located near a public or private airstrip. No impacts would therefore result and no mitigation measures would be required.

12. Population and Housing

Environmental Setting
The City of Brentwood has experienced cyclical population growth over the past few decades. Most recently, the community has experienced rapid residential growth, mirroring a strong Bay Area economy. Population forecasts prepared by the Association of Bay Area Governments (ABAG) as part of Projections 2005 indicate that anticipated population for the City is expected to be 45,700 by the year 2005, 53,500 by the year 2010, and 61,000 by the year 2020. These estimates included both incorporated City as well as the area within the adjacent sphere of influence.

Project Impacts
a) Induce substantial population growth in an area, either directly or indirectly? LS. The project, which is the City’s five-year Capital Improvement Program budget, is a planned response to the growth projected in Brentwood’s General Plan; the project itself does not result in that growth. Therefore, there would be no impact and no mitigation measures would be required.

b,c) Would the project displace substantial numbers of existing housing units or people? NI. No residential units will be displaced as a result of the proposed projects. Therefore, there would be no impact and no mitigation measures would be required.

13. Public Services

Environmental Setting
Public services are provided by the following agencies:

• Fire Protection. Fire protection is provided to the area by the East Diablo Fire Protection District, which provides structural fire suppression and rescue services from four stations and an administrative headquarters facility located within or immediately adjacent to the Planning Area. The District maintains mutual aid agreements with all other fire departments within the County.

• Police Protection. Police protection is provided by the Brentwood Police Department which is headquartered at 9100 Brentwood Boulevard. The Brentwood Police Department maintains a staff of approximately 62 sworn officers, plus support and reserve officers to provide police protection to the community.

• Schools. Educational facilities are provided by the Brentwood Union School District which operates kindergarten through eighth grade school services within the community and the Liberty Union High School District that provides grades 9-12 educational services.

• Maintenance. The City of Brentwood provides public facility maintenance, including roads, parks, street trees and other public facilities.

Environmental Impacts
a) Fire protection? NI. The Brentwood CIP contains a number of proposed projects that would serve to improve fire protection service in the community, including, new and upgraded water lines and water reservoirs to increase water quantity and pressure and improved roads to expedite emergency access to various portions of the community. Included in the roadway category are several proposed grade separation projects that, when complete, would eliminate emergency vehicle conflicts with trains. In addition, two new fire stations are included in the Community Facility portion of the proposed CIP budget. No impacts are anticipated and no mitigation measures would be needed.

b) Police protection? NI. The Brentwood CIP contains a number of proposed projects that would serve to improve police protection service in the community, including improved roads to expedite emergency access to various portions of the community. No impacts are anticipated and no mitigation measures would be needed.

c) Schools? NI. None of the proposed projects listed in the CIP involves the construction of new residences that would generate new school-aged children, so no impacts would result and no mitigation measures would be needed. The proposed CIP does include several projects to assist the local school district, such as joint use of a community theatre and gymnasium facilities with the Brentwood Unified School District

d) Maintenance of public facilities, including roads? NI. No impacts would result to maintenance, since CIP facilities, once constructed, would be built to City standard and would not require maintenance for a number of years. One of the proposed CIP elements is a pavement management program that would prioritize local roadways in need of maintenance. No mitigation measures would be needed.

e) Solid waste generation? LS. Construction of CIP projects would generate increased but less-than-significant levels of construction debris. Some of this debris could be recycled in the City's Solid Waste Transfer Facility located on Tresh Road, which is proposed to be improved as part of this CIP project. No mitigation measures are needed.

14. Recreation

Environmental Setting
The City of Brentwood has constructed several neighborhood and community parks and recreation services are provided by the City of Brentwood. Regional park facilities within the Brentwood area are provided by the East Bay Regional Park District.

Project Impacts
a) Would the project increase the use of existing neighborhood or regional parks? NI. None of the projects listed in the proposed CIP include additional residential development, which would increase the need for parks and recreation service. No impacts are therefore required and no mitigation measures would be needed.

b) Does the project include recreational facilities or require the construction of recreational facilities? LS. The proposed CIP includes a number of projects involving parks and recreational facilities, including an aquatic complex, Empire Avenue joint school and park facility, Sand Creek soccer complex, among others. A number of community trails are also proposed. Further environmental review of major parks and recreational facilities would occur at the time each individual project is proposed for construction. Less-than-significant impacts are anticipated and no mitigation measures are needed.

15. Transportation/Traffic

Environmental Setting
Regional access is provided to Brentwood via State Route 4, which is currently being upgraded through the community by the SR 4 Bypass. Major north/south arterial roads include Fairview Avenue, Minnesota Avenue, Walnut Boulevard and Sellers Avenue. Major east/west roadways include Lone Tree Way, Sand Creek Road, Central Avenue, and Balfour Road. In addition, many collector and interior roads provide access to individual neighborhoods and commercial areas.

Union Pacific Railroad lines bisect Brentwood in a northwest/southeast direction.

Project Impacts
a) Cause an increase in traffic which is substantial to existing traffic load and street capacity? NI. The proposed roadway improvements (which include developer improvements) listed in the CIP are anticipated to have a beneficial impact on traffic by increasing roadway capacity, increasing the number of linkage, and ease of traffic movements. No impacts are therefore anticipated and no mitigation measures are needed.

b) Exceed, either individually or cumulatively, a LOS standard established by the County CMA for designated roads)? NI. None of the CIP projects would generate sufficient traffic to have any impact on CMP roadways. No impacts would therefore result and no mitigation measures would be needed.

c) Change in a change of air traffic patterns? NI. The proposed project would have no impact on air traffic patterns, since none of the proposed project relate to air traffic. No mitigation measures would be required.

d) Substantially increase hazards due to a design feature or incompatible use? NI. The proposed roadway improvements (which include developer improvements) are anticipated to reduce hazards due to undersized streets and similar conditions. This would include Brentwood Boulevard widening, American Avenue extension. Logan Extension, Empire Avenue extension north and others identified on Table 1. All facilities constructed pursuant to an approved CIP would comply with City design standards, therefore, the proposed project is anticipated to have no impact with regard to increases in safety hazards.

e) Result in inadequate emergency access? NI. Construction of projects proposed in the CIP would serve to improve emergency access, through construction of new and improved roads. This would include the proposed grade separation of Lone Tree Way and the Union Pacific Railroad tracks in the northerly portion of Brentwood. No impacts are therefore anticipated and no mitigation measures are needed.

f) Inadequate parking capacity? NI. Parking for individual projects constructed as part of the CIP would contain on-site parking, per the City's Zoning Ordinance. Therefore, no impacts are anticipated and no mitigation measures are needed. The proposed downtown parking garage would increase the parking availability in the downtown area, allowing for increased use of activities in the downtown core.

g) Hazards or barriers for pedestrians or bicyclists? NI. The project does not conflict with adopted policies, plans or programs supporting alternative transportation. Individual projects are reviewed for consistency with the General Plan as well as for conformance with adopted policies, plans or programs supporting alternative transportation. Proposed projects included in the CIP include a construction of a number of trails and a city-wide sidewalk replacement program. No impacts are therefore anticipated and no mitigation measures are needed.

16. Utilities and Service Systems

Environmental Setting
The City of Brentwood is served by the following service providers:

• Electrical and natural gas power: Pacific Gas and Electric Co.

• Communications: AT&T and Comcast Cable

• Water supply and sewage treatment: City of Brentwood

• Storm drainage: City Brentwood and Contra Costa County Flood Control District

• Solid waste disposal: City of Brentwood

Environmental Impacts
a) Exceed wastewater treatment requirements of the RWQCB? NI. The project, which is the City’s five-year Capital Improvement Program budget, is a planned response to the growth projected in Brentwood’s General Plan; the project itself does not result in that growth. Therefore, the project does not exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board. No impact is anticipated and no mitigation measures are required.

b) Require new water or wastewater treatment facilities or expansion of existing facilities? NI. The proposed project itself does not result in that growth. It reflects the City’s response to projected growth and includes improvements to the City’s wastewater treatment and conveyance system as listed in Table 1. No impact is anticipated and no mitigation measures are required.

c) Require new storm drainage facilities? NI. The proposed project does not include new residential or non-residential components. It is instead a planned response to Brentwood’s projected population growth as set forth in the adopted General Plan. The City’s response to projected growth includes improvements to the City’s storm water system as listed in Table 1. No impact is anticipated and no mitigation measures are required.

d) Are sufficient water supplies available? LS. The project, which is the City’s five-year Capital Improvement Program budget, is a planned response to the growth projected in Brentwood’s General Plan; the project itself does not result in that growth. The City’s response to projected growth includes improvements to the City’s water. Specific projects included in the CIP may have a potential to increase demand for water supplies, including construction of new neighborhood parks, fire stations, a city hall and other new landscaping. Requirements for additional water to serve these facilities will be reviewed at the time actual construction is proposed. Less-than-significant impacts are anticipated and no mitigation measures are required at this stage in the environmental review process.

e) Adequate wastewater capacity to serve the proposed project? LS. Minimal additional wastewater capacity is anticipated for a majority of proposed projects included in the most recent CIP. A number of potential projects, such as construction of new local parks and two fire stations, may require new wastewater connections. These are believed to be less-than-significant and the need for additional wastewater generation would be reviewed at the time projects are proposed for construction.

f, g) Solid waste disposal, including compliance with all solid waste regulations? LS. Construction of certain individual projects included within the CIP may generate additional quantities of solid waste, including additional amounts of construction debris. Operation of certain projects would also increase solid waste generation, including construction of new local parks and a fire station. The amount of additional solid waste is anticipated to be less-than-significant and no mitigation measures are required at this stage of environmental review. One of the proposed community facility projects listed on Table 1 includes improvements to the City’s solid waste transfer station. Construction of new civic facilities included in the CIP would comply with local recycling requirements as well as state and federal solid waste requirements.

17. Mandatory Findings of Significance

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 wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number of or restrict the range of a rare or endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? No. The preceding analysis indicates that the proposed project would not have a significant adverse impact on overall environmental quality.

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 other current projects and the effects of probable future projects). No, although incremental increases in certain areas can be expected as a result of constructing this project, including additional traffic, air emissions, light and glare, increases in demands for public services and noise, the project is consistent with the Brentwood General Plan and would not result in a significant individual or cumulative impacts.

c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? No. No such impacts have been discovered in the course of preparing this Initial Study.
