Resolution approving Mitigated Negative Declaration for Fire Station No. 18 2. Mitigated Negative Declaration for Fire Station No. 18 RECOMMENDATION.~./~,~I. Adopt resolution approving Mitigated Negative Declaration for Fire Station No. 18. FINANCIAL STATEMENT: None PROJECT DESCRIPTION: At the City Council meeting on June 4, 2002, the City Council reviewed the designs for Municipal Fire Stations No. 17 and 18 and authorized the preparation of construction documents for the two facilities. Prior to the issuance of building permits, the environmental documentation for the project must be approved. Mitigated Negative Declarations were prepared for the two projects and circulated in accordance with the California Environmental Quality Act (CEQA) Guidelines. A resolution approving the Mitigated Negative Declaration for Fire Station No. 18 is included as Attachment 1. The proposed Fire Station No. 18 project consists of the construction of a municipal fire station to serve the eastern portion of Dublin. The fire station is to be located on the western side of Fallon Road at its 'intersection with Bent Tree Drive in Dublin Ranch. The site is approximately 1 acre and is currently vacant. The proposed fire station building is 8,945 square feet. The project includes the construction of the fire station, 10 on-site parking spaces (one of which is disabled-accessible), associated landscape improvements, and a service bay for the fire trucks. Construction of the proposed project would change the character of the site from open space to a built area, although the area immediately adjacent to the project site is proposed to remain open space and is the site of a proposed Community Park. Fire Station No. 18 will be constructed by DR Acquisitions, LLC, pursuant to conditions of apProval and an improvement agreement that implements the conditions of approval. The fire station will not be accepted by the City until it is completed and deemed compliant with the approved design and City standards. BACKGROUND: An Initial Study was prepared by the City of Dublin in May 2002 to assess the potential environmental effects of the proposed fire station based upon location, planning staff review, field review, comments COPIES TO: Applicant ' In House Distribution G:LPA#X2002\02-010\CC Staff Report FS no 18 Mit Neg Dec.doc ITEM NO. from the City and other local agencies, studies prepared by consultants, use of City Planning documents, CEQA Law and Guidelines, and City of Dublin CEQA Guidelines. The analysis is intended to satisfy the requirements of the California Environmental Quality Act and to provide the City with adequate information for project review. The public review period for the environmental documents was 20 days and began on May 13, 2002 and ended on June 3, 2002 at 5:00 p.m. In summary, the Initial Study concluded that the project would not pose any significant environmental impacts with the implementation of the mitigation measures as described in Attachment 2. Comments Received: Comments were received from the Alameda County Flood Control and Water Conservation District (Zone 7) regarding the payment of impervious surface impact fees and floodplain drainage issues. Those comments were incorporated into the final Mitigated Negative Declaration and no additional action is necessary. CONCLUSION: With the mitigation measures outlined in the Mitigated Negative Declaration, which will be incorporated into the plans and the construction activities for Fire Station No. 18, no significant adverse environmental impacts will result from the implementation of this project. After the Mitigated Negative Declaration is approved by the City Council, a Notice of Determination will be filed by Staff, notifying local agencies and the general public of the action that has been taken. RECOMMENDATION: Staff recommends that the City Council adopt a resolution approving the Mitigated Negative Declaration for Fire Station No. 18 (Attachment 1).

The Initial Study consists of a completed environmental checklist and a brief explanation of the environmental topics addressed in the checklist. 1. Project title: City of Dublin Fire Station No. 18. Project includes approximately 8,945 square feet of building with associated parking, landscaping, and site improvements. 2. Lead agency: City of Dublin 100 Civic Plaza Dublin CA 94588 3. Contact person: Kristi Bascom, Dublin Community Development Department (925) 833-6610 4. Project location: The project site is located on the southwest side of Fallon Road where it intersects with Bent Tree Drive in the eastern Dublin neighborhood known as Dublin Ranch. Exhibit 1 depicts the location of the project area in context of the larger City of Dublin and Exhibit 2 depicts the fire station site in relation to Eastern Dublin. 5. Project sponsor: City of Dublin Parks and Community Services Department Herma Lichtenstein, Manager, Parks and Facilities Development 100 Civic Plaza Dublin CA 94588 6. Specific Plan/General Plan designation: Community Park 7. Zoning: Planned Development 8. Public agency required approvals: Grading and Building permits (City of Dublin) Sewer and water Connections (DSRSD) Encroachment permits (City of Dublin) City of Dublin Page 3 Initial Study and Mitigated Negative Declaration for Fire Station No. 18, PA 02-010 May 6, 2002 Project Description and. Context The project site is located within the Eastern Dublin Specific Plan/General Plan Amendment area. This Specific Plan/General Plan was adopted by the City of Dublin in 1994 for the purpose of directing long-term land use, circulation, infrastructure and environmental protection for 3,302 acres of land located east of the central portion of Dublin and north of the 1-580 freeway. At full build-out, the Eastern Dublin planning area would allow a range of residential, commercial office, employment, recreation, and open space uses. The proposed project involves construction of a municipal fire station to serve some of the recently- developed neighborhoods in Eastern Dublin. The fire station site is approximately 1 acre and is currently vacant. The site has a substantial slope to the southwest. The proposed fire station building is 8,945 square feet. In addition, the site would include 10 parking spaces (one of which is disabled-accessible) and a wash bay for the fire trucks. Xccess to the site would be provided by two driveways off Fallon Road, one of which will be in line with the Bent Tree Drive intersection and one' of which will be immediately north. At this time Fallon Road is built as a half road which will be fully constructed once development in the Area A portion of Dublin Ranch is completed. Unless Fallon Road is constructed in its entirety before the fire station is constructed, the City will have to construct the portion of Fallon Road in front of the fire station so access to the site is acceptable. Landscape improvements would also be constructed as part of the project. Landscaping would be located around the perimeter of the site, within the surface parking lot, and adjacent to the fire station. Other actions Grading activities would occur on the site to accommodate the proposed fire station, parking area, and utilities. A preliminary grading plan has been submitted as part of this application. Water, sewer and recycled water services would be proVided by Dublin San Ramon Services District (DSRSD) in accordance with DSRSD's Eastern Dublin Facilities Master Plan. Sewer service for the project would be accommodated through connection to the existing sewer system owned and maintained by the Dublin San Ramon Services District (DSRSD). When available, recycled water from DSRSD would be used for irrigation purposes, reducing the need for potable water.

I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a "potentially significant impact" or "potentially significant unless mitigated" impact 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 the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required. Signature: ~"~l~'~:~t~.._. Date: ~[IoIo7,. Printed Name: [~-'1(' I' ~lf i ~ ~t. ¢ l;. ~ For: City of Dublin Page 10 Initial Study and Mitigated Negative Declaration for Fire Station No. 18, PA 02-010 May 6, 2002 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 parentheses 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 standards (e.g., the project will not expose sensitive receptors to pollutants, based on a proj ect-specific screening analysis). 2) All answers must take account of the whole action involved, 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) Once the lead agency has determined that a particular physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant ~vith mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect may be significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4) "Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" 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 (mitigation measures from Section XVII, "Earlier Analyses," may be cross-referenced). 5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). In this case, a brief discussion should identify the following: a) Earlier Analysis Used. Identify and state where they are available for review. b) Impacts Adequately Addressed. Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation Measures. For effects that are "Less than Significant with Mitigation Measures Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7) Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8) This is only a suggested form, and lead agencies are free to use different formats; however, lead agencies should normally address the questions from this checklist that are relevant to a project's environmental effects in whatever format is selected. 9) The explanation of each issue should identify: a) the significance criteria or threshold, if any, used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significance City of Dublin Page 11 Initial Study and Mitigated Negative Declaration for Fire Station No. 18, PA 02-010 May 6, 2002 EnVironmental :Impacts (NOte: SOurce of determination listed in parenthesis.

City of Dublin Page 20 Initial Study and Mitigated Negative Declaration for Fire Station No. 18, PA 02-010 May 6, 2002 Attachment to Initial Study: Discussion of Checklist Proiect Impacts and Mitigation Measures I. Aesthetics a-d) Significant impact on scenic vista; damage to scenic resource, degrade visual character of the site or create light or glare? Less than significant. Construction of the proposed project would change the character of the site from open space to a built area, although the area immediately adjacent to the project site is proposed to remain as open space and be used as a Community Park. The construction of the proposed fire station in this location will' nOt add additional visual impacts that have not already taken place due to the construction of residences in the immediate vicinity. Aesthetic impacts of construction in the Eastern Dublin Specific Plan area as a whole were addressed in the Eastern Dublin Specific Plan/General Plan Amendment EIR. Despite the inclusion of mitigation measure no. 3.8/4.0 which requires that grading be done sensitively to reduce visual impacts, the EIR concluded that alteration of visual character of the hillside and flatland areas are significant and unmitigatable impacts and. were included in the Statement of Overriding Considerations. No impacts not previously analyzed in the Eastern Dublin Specific Plan/General Plan Amendment EIR are expected to occur as a result of the proposed project. II. Agricultural Resources a-c) Convert Prime Farmland, conflict with agricultural zoning or convert prime farmland to a non- agricultural use? Less than significant. Although the greater area near the site has historically been used for agriculture, the underlying soil is not considered primary agricultural soil and no Williamson Act Land Conservation Agreement exists on the project site. The Eastern Dublin Specific Plan/General Plan Amendment EIR found that discontinuance of agricultural operations is an insignificant impact based on the large number of non-renewal notices being filed on Williamson Act Agreements within the Eastern Dublin area. Similarly, loss of farmland of local importance in the area would be considered a less-than-significant impact due to the fact that on-site soils are not prime agricultural soils. No impacts not previously analyzed in the Eastern Dublin Specific Plan/General Plan Amendment EIR are expected to occur as a result of the proposed project. III. Air Quality a) Would the project conflict or obstruct implementation of an air quality plan ? Less than significant. The proposed project would not conflict with the local Clean Air Plan City of Dublin Page 21 Initial Study and Mitigated Negative Declaration for Fire Station No. 18, PA 02-010 May 6, 2002 adopted by the Bay Area Air Quality Management District, since the proposed amount of development square footage has been included in Dublin's planned growth as part of Eastern Dublin Specific Plan/General Plan. Therefore, such impacts would be less-than-significant. b) Would the project violate any air quality standards? Less than significant. Short-term construction impacts related to implementation of the project, including grading and excavation, could result in exceeding air quality standards established by the Bay Area Air Quality Management District. Adherence to Mitigation Measures nos. 3.11/1.0, 3.11/2.0, and 3.11/12.0 of the Eastern Dublin Specific Plan/General Plan Amendment EIR will reduce short-term air quality impacts to a less-than-significant level. These measures minimize the creation of fugitive dust during grading and construction activities and also mandate that construction equipment be kept in proper running order. The proposed fire station itself, however, will generate a minimal level of air quality impacts due to the low level of vehicular emissions and few stationary sources. c) Would the project result in cumulatively considerable air pollutants ? Less than significant. The Eastern Dublin Specific Plan/General Plan Amendment EIR identifies Mobile Source Emissions and Stationary Source Emissions as significant irreversible impacts. Generally sUCh impacts are based on vehicular emission from furore traffic within the sub-region as well as stationary sources. This project will not generate significant amounts of traffic and therefore vehicular emissions are estimated to be minimal and no additional environmental analysis is necessary. d,e) Expose sensitive receptors to significant pollutant concentrations or create objectionable odors? Less than significant. The proposed fire Station project is not considered a land use that includes sensitive receptors. In sum, air quality impacts associated with the proposed fire station are expected to be less than significant and have been addressed in the Eastern Dublin Specific Plan/General Plan Amendment EIR. No impacts not previously analyzed in the Eastern Dublin Specific Plan/General Plan Amendment EIR are expected to occur as a result of the proposed project. IV. Biological Resources a) Have a substantial adverse impact on special-status species, riparian features, movement offish or wildlife species, or conflict with Habitat Conservation Plan ? Less than significant. Potential impacts to rare, threatened or endangered species have been addressed in the Eastern Dublin Specific Plan/General Plan Amendment EIR as well as several additional studies conducted since the EIR was certified by the City in 1994. These studies include rare plant surveys, wetlands jurisdictional studies, and studies regarding sensitive-species and endangered species, including the San Joaquin kit fox, fairy shrimp, golden eagle and a variety of amphibians and reptiles. City of Dublin Page 22 Initial Study and Mitigated Negative Declaration for Fire Station No. 18, PA 02-010 May 6, 2002 However, no impacts are anticipated with regard to wetlands, wildlife corridors, or riparian features on the proposed fire station site, since none have been observed at this site and the site is outside of Sensitive wetland areas. A memorandum (Source No. 7) from the Dublin City Manager to the City Parks and Facilities Development Manager confirmed that the proposed fire station site does not fall under the jurisdiction of the U.S. Army Corps of Engineers. Mitigation measure nos. 3.7/5.0 and 3.7/19.0 ensure that any disturbed areas are revegetated as soon as possible and that the use of rodenticides and herbicides be limited to minimize impacts to wildlife. The site grading plan contained in this document shows the areas of disturbance due to development of the site and new construction will be over fifty (50) feet from any Army Corps jurisdictional boundaries. The limit of disturbance will be a minimum of fifteen (15) feet from the adjacent creek and steps will be taken during construction to minimize impacts on the resource. Additionally, the proposed fire station site is not located within a Habitat Conservation area. No impacts not previously analyzed in the Eastern Dublin Specific Plan/General Plan Amendment EIR are expected to occur as a result of the proposed project. V. Cultural Resources a-d) Cause substantial adverse change to significant historic, archeological or paleontological resources or human remains? Less than significant. The Eastern Dublin Specific Plan/General Plan Amendment EIR identified a number of potentially significant impacts associated with development in eastern Dublin, including disruption or destruction of prehistoric resources, and disruption to historic resources. Although there are no historic structures on this site and no known prehistoric or archeological resources, mitigation measure no. 3.9/5.0 of the Eastern Dublin Specific Plan/General Plan Amendment EIR insures that should any resources be located during grading and/or construction, activities at the site will cease until the situation can be properly assessed. No impacts not previously analyzed in the Eastern Dublin Specific Plan/General Plan Amendment EIR are expected to occur as a result of the proposed project. VI. Geology and Soils a-e) Expose people or structures to potential substantial adverse impacts, including loss, injury or death related to ground rupture, seismic ground shaking, ground failure, landslide, substantial erosion, unstable soils, or liquefaction? Less than significant. The Eastern Dublin Specific Plan/General Plan Amendment EIR identifies several potential impacts to soils and geology, including earthquake and ground shaking, ground rupture, seismic ground shaking, impacts to groundwater resources, shrink-swell potential due to expansive soils, slope stability, erosion and sedimentation. City of Dublin Page 23 Initial Study and Mitigated Negative Declaration for Fire Station No. 18, PA 02-010 May 6, 2002 No known active or potentially active faults traverse the project site, and Alquist-Priolo Special Studies Zones are not located within the site. The potential for fault ground rupture is therefore considered to be minimal. Nonetheless, the Eastern Dublin Specific Plan/General Plan Amendment EIR noted that potential groundshaking effects could result from large earthquakes on active fault zones in the region. The previously adopted mitigation measures will be applied to this project, and will reduce but not completely eliminate all hazards associated with groundshaking. Mitigation measure nos. 3.6/1.0-7.0, 3.6/11.0, 3.6/12.0, and 3.6/18.0-28.0 of the Eastern Dublin Specific Plan/General Plan Amendment EIR relating to seismic stability, soil compaction, grading, structural design, and will reduce soil and geologic impacts for the fire station site to a level of less-than-significant. A statement of ovenfding considerations was previously adopted with the Eastern Dublin GPA/SPA. No impacts are anticipated with regard to septic systems, since on-site sewers would be connected to the local sanitary sewer system. No new impacts not previously analyzed in the Eastern Dublin Specific Plan/General Plan Amendment EIR are expected to occur. VII. Hazards and Hazardous Materials a-g) Create a significant hazard through transport of hazardous materials or release or emission of hazardous materials, listed as a hazardous materials site, interference with an emergency evacuation plan, subject to wildland fires, or located near a public or private airstrip? Less than significant. The proposed project would involve construction and operation of a fire station on the site. Significant amounts of hazardous materials would not be manufactured, used, stored or transported as part of the project. The proposed project will contain small quantities of motor oil, waste oil, and coolant materials. The applicant will be required as part of the storage of those materials to file a hazardous material management plan (HMMP) with the Alameda County Environmental Health Services (EHS). Enforcement of EHS's requirements of the HMMP will assure that the materials are stored in a safe manner and will reduce the risk of accidental explosion or release of hazardous substances to an insignificant level. . Since the site would be converted from a vacant, undeveloped parcel to an urbanized condition, risk of wildland fire would be minimal and considered less-than-significant. No impacts are anticipated with regard to aircraft, since the project site is not located within or near any crash hazards zones of any public or private airfield or airstrip. In sum, risks of hazardous material impacts would be less-than-significant and no mitigation measures are required. City of Dublin Page 24 Initial Study and Mitigated Negative Declaration for Fire Station No. 18, PA 02-010 May 6, 2002 VIII. Hydrology and water Quality a-i) Violate any water quality standards or waste discharge requirements, deplete groundwater resources, alter drainage patterns, effect surface or subsurface water quality, result in placing housing in a flood plain ? Less than significant. The City of Dublin is a co-permittee of the Alameda County Clean Water Program, which is a coordinated effort by local governments in the County to improve water quality in the San Francisco Bay. In 1994, the San Francisco Bay Regional Water Quality Control Board issued a set of recommendations for New and Redevelopment Controls for Storm Water Programs. These recommendations include policies that define watershed protection goals, minimum non-point source pollution controls for site planning and post construction activities. Watershed protection goals are based on policies identified in the San Francisco Bay Basin Water Control Plan, which relied on Best Management Practices (BMPs) to limit pollutant contact with stormwater runoff at its source and remove such pollutants prior to being transported into receiving waters. Adherence to mitigation measures nos. 3.5/4.0, 3~5/5.0, 3.5/12.0, 3.5/16.0, 3.5/20.0, 3.5/27.0, 3.5/37.0, 3.5/47.0, 3.5/49.0, 3.5/53.0, 3.5/54.0, and 3.5/55.0 of the Eastern Dublin Specific Plan/General Plan Amendment EIR will reduce surface water quality pollution to a level of insignificance by addressing wastewater collection and treatment and protecting water quality. Although the natural drainage pattern of the fire station site will be altered, the site will be graded to provide adequate drainage to avoid on- and off-site flooding. Any loss of floodplain will be addressed at the time of site grading. Additionally, any additional impervious surface will be subject to Alameda County Flood Control and Water Conservation District (Zone 7) Special Drainage Area fees. There will be no impacts with regard to exposing people to flooding, since the site would involve non-residential land uses. Similarly, the project site is located some distance from any major body of water that could cause impacts due to a tsunami or seiche. Development of the proposed fire station would be consistent with previous actions and environmental documentation approved by the City of Dublin and no additional mitigation measures are required. IX. Land Use and Planning a) Physically divide an established community? No Impact. The project site is vacant and has been planned for community uses since the original adoption of the Eastern Dublin Specific Plan/General Plan Amendment in 1994. Therefore there would be no disruption of any established community. b) Conflict with any applicable land use plan, policy or regulation ? No impact. The proposed project is consistent with the goals and policies contained in both the City of Dublin Page 25 Initial Study and Mitigated Negative Declaration for Fire Station No. 18, PA 02-010 May 6, 2002 Eastern Dublin Specific Plan and General Plan, which indicates that the site is designated for Public/Semi-Public facilities and Park/Public recreation. The fire station use is compatible with the Planned Development zoning .designation and a change to the district is not required per the City's Zoning Ordinance. c) Conflict with a habitat conservation plan or natural community conservation plan ? No impact. No such plan has been adopted within the Eastern Dublin Specific Plan area. There would therefore be no impact to a habitat conservation plan or natural community conservation plan for the proposed fire station site. X. Mineral Resources a, b) Result in the loss of availability of regionally or locally significant mineral resources? No impact. The Eastern Dublin Specific Plan/General Plan Amendment EIR does not indicate that significant deposits of minerals exist on the site, so no impacts would occur. XI. Noise a-f) Would the project expose persons or generation of noise levels in excess of standards established by the General Plan or other applicable standard, expose people to groundborne vibration, result in permanent increases in ambient noise levels? Less than significant. The Eastern Dublin Specific Plan/General Plan Amendment EIR addressed potential noise impacts of adopting and implementing the Eastern Dublin Specific Plan/General Plan. Noise related impacts identified in the EIR included exposure of future residents to increased levels of noise, exposure of existing residents near the site to increased noise levels, exposure of future residents to military operations at Camp Parks, exposure of residents to construction noise, and noise impacts emanating from mixed use developments in the Eastern Dublin Specific Plan area. Mitigation measure no. 3.10/5.0 will mitigate minimize construction noise impacts to a level of less-than-significant. However, short-term construction related noise can be expected which could be considered significant based on specific types of equipment which may be used in the construction process. Common practices is for all construction activities on the project site to be limited to 7 a.m. to 5 p.m., Monday through Friday, unless alternative hours are approved by the Dublin Building Official for structural construction and the City Engineer for grading activities. Construction equipment, including compressors, generators, and mobile equipment, shall be fitted with properly working mufflers. The noise impacts from the proposed fire station on a day-to-day basis should be minimal. However, there will be intermittent noise generated by the fire station when sirens sound at the time of a fire. The sirens serve to notify the firefighters as well as the community that fire trucks will soon be leaving the site. This is a noise impact that can not be mitigated as the sirens serve a crucial purpose for station and people nearby. To reduce the noise impact would also reduce the effectiveness of the warning system, which would be detrimental to the neighborhood as a whole. City of Dublin Page 26 Initial Study and Mitigated Negative Declaration for Fire Station No. 18, PA 02-010 May 6, 2002 Overall, noise impacts at the site would be less-than-significant and no additional mitigation measures are required. XII. Population and Housing a) Induce substantial population growth in an area, either directly or indirectly? No impact. Construction of the fire station will not induce grOwth in the Eastern Dublin Specific Plan area that has not already been accounted for. A fire station in the Eastern Dublin area is required to serve residential units that have already been approved, and in some cases, already built. Therefore, no population growth impacts are anticipated as a result of this project and no mitigation measures are required. b,c) WouM the project displace substantial numbers of existing housing units or people? No impact. The site is vacant. Construction of the proposed project would therefore displace neither housing units nor residents. XIII. Public Services a-e) Potential impacts related to: fire protection, police protection, schools, maintenance, or solid waste generation ? Less than significant. The construction and operation of the proposed fire station will not create a substantial need for new public services or facilities. XIV. Recreation a, b) WouM the project increase use of existing neighborhood or regional parks or require the construction of new recreational facilities? No impact. The approval and construction of the proposed fire station will not result in an increased use of park or recreation facilities. XV. Transportation/Traffic a-g) Cause an increase in traffic which is substantial to existing traffic load and street capacity, exceed LOS standards for CMA roadWays, change of air traffic patterns, increase traffic safety hazard, provide for inadequate emergency vehicle access, inadequate parking, provide hazard or barrier to alternative transportation modes? No impact. No impacts are anticipated with regard to traffic or parking for the proposed fire station. The station will have ten parking spaces on site and the amount of traffic generated to and from the site should be minimal because of the type of use and low number of employees on- site. City of Dublin Page 27 Initial Study and Mitigated Negative Declaration for Fire Station No. 18, PA 02-010 May 6, 2002 XVI. Utilities and Service Systems a-g) Exceed wastewater treatment requirements of the RWQCB, require new or expanded water or wastewater treatment facilities, require new storm drain facilities, require additional water supplies, require new or expanded wastewater treatment facilities, or require new solid waste facilities? Less than significant. Since the subject site is currently vacant and without urban services, the construction of the proposed fire station will result the requirement of water and wastewater services. However, service has already been provided to properties adjacent to the subject property therefore the extension of such services will not be significant. Based on the size of the proposed fire station, the requirement for new water and wastewater lines will not trigger the need for new facilities to serve those lines, and therefore no mitigation is required. XV. 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 will not have a significant adverse impact on overall environmental quality, including biological resources or cultural resources, with the implementation of mitigation measures included in the Eastern Dublin Specific Plan/General Plan Amendment EIR. 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, the project site lies within an area with an approved specific plan. Mitigation measures are included in an approved EIR that would reduce many impacts to less-than-significant levels. c) Does the project have environmental effects that will cause substantial adverse effects on human beings, either directly or indirectly? No such impacts have been discovered in the course of preparing this Initial Study.
