A Zone 7 channel and storm drain outfall abuts the southeasterly boundary of the site. Project development ~vould not encroach into the Caltrans 1-680 right- of-xvay or the Zone 7 channel. The site contains an existing retail center and parking lot for a total of approximately 48,400 square feet. The project site comprises about 4.6 acres. Pear trees are located along the San Ramon Road frontage with Monterey pines and shrubs planted at the easterly perimeter of the properU, and several elm trees located at the southerly portion of the property. Additional trees are dispersed throughout the parking lot. Project Des~Tiption The proposed project consists of a General Plan Amendinent from Retail/Office to Mixed- Use (Retail/Office, Medium Density Residential); a Stage 1 Development Plan to establish zoning of the site; a State 2 Development Plan to establish standards for development of the site; a Vesting Tentative Map and Site Development Permit for review of design and architectural features to provide for the revitahzation of a portion of an existing retail center and the construction of residential townhouse units. Of the 48,400 square feet of existing retail space, approximately 34,000 square feet would be demohshed to construct residential town homes. The remaining 14,400 square feet of retail space would be remodeled and designed to compliment the residential project and create a village type neighborhood. The remodeled retail development xvould include nexv roof lines and the building surface would be colored stucco. Metal roofing and awnings, ne~v signage and hghting would provide architectural detail. Building heights would range from about 19 feet to 32 feet. Landscaping would include planters, new trees and shrubs in the parking lot and building perimeters and nexv pear street trees along Alcosta Boulevard. The parking lot would provide 93 parking spaces. The residential development would be constructed on the southern half of the properts~. Primary access to the town homes would be off of Bellina Street with secondary access through the retail component onto San Ramon Road and Alcosta Boulevard. The toxvnhome-s~le condominiums would consist of 56 units distributed throughout eleven three-storey buildings with a garage on the f-mst floor and two levels of residential space. The maximum building height xvould be approximately 41.5 feet. The toxvn homes would be two and three bedroom units ranging in size between 1,218 square feet and 1,654 square feet. San Ramon Village Plaza Mitigated Negative Declaration - Page 2 The project would include seven below market rate units. The building surface xvould be colored stucco with asphalt tile roofs. Balconies and porch areas xvould have xvrought iron railings. Parking for the residential development would include 112 spaces (two spaces for each townhouse garage) and 28 non-designated guest spaces located on site. Three landscaped open space areas are located in the residential development. There is a tot lot located at the central portion of the development; a sitting garden with public art is located at the corner of Bellina Street and San Ramon Road; and a sitting garden is located at the easterly project boundau'. General landscaping throughout the residential development would include trees and other plantings. A six-foot high wrought iron fence with hedge border ~vould be located along the ~vesterly and southerly perimeters of the residential development. A wrought iron fence with panels would be located at the northeasterly pordon of the residential development. Trees and other plantings would be installed along pedestrian pathways. The pedestrian pathways connect the residential buildings and provide access to the open space areas, tot lot and retail development. The project will require a general plan amendment from Retail/Office to Medium-High Density on 2.94 acres of the project site. The site is currently zoned C-N, C-1 and C-2 and will require a rezone to Planned Development to allow- the proposed mixed use program. A Stage 2 Development Plan will be required to establish permitted, conditionally permitted and accessory uses, site area and maximum densities, ma:dmum number of residential units by U~pe and non-residential square footage, development regulations, architectural standards, circulation system preliminary landscape plan and any other information necessary for the review of the proposed project. A Site Development Permit must be granted to ensure the proposed project is consistent with the development regulations and requirements of the PD/Stage 2 Development Plan. The project applicant is proposing to split the project site into two lots, which will require a Vesting Tentative Map for subdivision of the property into two lots. It is anticipated project construction vAll take approximately one and one-half to two years. PROJECT LOCATION San Ramon Village on San Ramon Road between Bellina Street and Alcosta Boulevard in Dublin, California. PROJECT SPONSOR Michael Banducci Bancor Properties LLC 1459 First Street Livermore, California 94550 FINDING The project will not have a significant effect on the environment based on the Initial Study prepared according to CEQA Guidelines. Mitigations have been incorporated into the project to reduce all potentially significant impacts to a less than significant level. San Ramon Village Plaza Mitigated Negative Declaration - Page 3 POTENTIALLY SIGNIFICANT IMPACTS The attached Initial Study indicates that the project could adversely affect the environment. The folloxving potentially significant impacts xvere identified: Potentially significant air quality impacts during construction. · Potentially significant impacts to unknown cultural resources · Project improvements may be subject to strong seismic ground sha~ng. · Soil contaminated with Residential PRGs · On-site erosion during construction activities. · Temporau7 noise impacts during construction activities. · Permanent noise impacts due to traffic. MITIGATION MEASURES In the interest of reducing the potential impacts to the point where the net effect of the project is insignificant, mitigation measures are recommended. A discussion of the potential impacts of interest and the associated mitigation measures is provided below. Impact: Temporau' construction activities may adversely affect air quality. Mitigation Measures: 3.1 Construction contractors shah be required to xvater all active earth construction areas at least twice daily. 3.2 Construction contractors shah be required to cover all trucks hauling soil, sand and other loose materials or require all trucks to maintain at least two feet of freeboard. 3.3 3.4 Construction contractors shall be required to sweep daily (preferably xvith water sweepers) all paved access roads, parking areas and staging areas at construction sites. If visible soil material is carried onto adjacent public streets, require construction contractor to sweep streets daily. 3.5 Construction contractor shah be required to enclose, cover or apply (non-toxic) soil binders to exposed stockpiles (dirt, sand, etc.). 3.6 Construction contractor shall be required to install sandbags or other erosion control measures identified in the project's Storm Water Pollution Prevention Plan. Residual Impact: Less than significant with mitigation measures. Impact: Unknown cultural resources may be impacted. Mitigation Measure: Should any cultural materials or human remains be exposed or discovered during earth moving activities, the following mitigation measures shall be implemented: 5.1 Operations shall stop within 100 feet of the find and a qualified professional archaeologist shall be contacted for further reviexv and recommendations. San Ramon Village Plaza Mitigated Negative Declaration - Page 4 5.2 If human remains are discovered, the Alameda CountT Coroner shall be notified. The Coroner would determine whether or not the remains were Native American. If the Coroner determines the remains are not subject to his authority, the Native American Heritage Commission will be notified, who xvould attempt to identi~7 descendants of the deceased Native American. 5.3 If the Community Development Director finds that the archaeological find is not a significant resource, xvork would resume only after the submittal of a preliminary archaeological report and after provision for reburial and ongoing monitoring accepted. Provisions for identifying descendants of a deceased Native American and for reburial would follow the protocol set forth in the CEQA Guidelines. If the site is found to be a significant archaeological site, a mitigation program xvill be prepared and submitted to the CommuniuT Development Director for consideration and approval in conformance with the protocol set forth in the CEQA Guidelines. Residual Impact: Less than significant with the mitigation measure. Impact: There is a potential of ground shaking hazards to people, structures and property. Mitigation Measures: 6.1 Implement the recommendations identified in the geotechnical investigation prepared by Terrasearch, Inc. (2002). 6.2 Any changes in grading or building design that would be significantly affected by geologic hazards or soils conditions, or in turn ~vould significantly alter geologic or soils conditions, shah be accompanied by a re-analysis of those conditions. In addition, any conditions discovered during excavation or grading that significantly depart from the previously described geologic and soils setting shall be evaluated. Residual Impact: Less than significant with mitigation measures. Impact: Soils have been contaminated ~vith Residential PRGs. Mitigation Measures: 7.1 Affected soil exceeding the Residential PRGS shall be excavated and removed from the site as hazardous waste. Once cleaned up, a human Health Risk Assessment shall be prepared to demonstrate that soil gas emanating from the site will not pose a health threat to future site residents. 7.2 A site Health and Safety Plan shall be prepared that documents the appropriate protocol for construction personnel that may come in contact ~vith contaminated soils. 7.3 Prior to demolition, the three roof sections of the building shah be sampled to determine if they contain asbestos. If it is determined asbestos is present, it shah be disposed of as a hazardous material. 7.4 Site clean up and remediadon shah be required to meet all federal, state and local regulations. Residual Impact: Less than significant with mitigation measures. San Ramon Village Plaza Mitigated Negative Declaration - Page 5 Impact: There is a potential for erosion during construction activities. Construction activities xvould generate additional pollutants such as oil, grease and heavy metals. Mitigation Measures: 8.1 A Storm Water Pollution Prevention Plan shall be prepared in compliance with the NPDES permit included in the erosion control measures appropriate for the project. Design of these measures shall be updated each year prior to September 30 and approved by the Engineer. Residual Impact: Less than significant with mitigation measures. Impact: Construction-related noise could adversely affect nearby residential development. Mitigation Measures: 11.1 Applicant shall prepare a construction noise mitigation plan. The plan shall include but not be limited to the following: · Construction phasing plan showing the duration of each phase and equipment to be used. · Location of stationao' equipment. · Calculation of noise levels at nearest residences and noise sensitive retail spaces. · Name of construction noise coordinator that can be posted at the entry to the site. Person responsible for responding to complaints and enacting solutions. Residual Impact: Less than significant with mitigation measures. Impact: Traffic noise could adversely affect the proposed residential development. 11.2 Sound-rated building construction shall be used to achieve acceptable indoor noise levels as per the State Building Code and City's Noise Element. The specification of these treatments should be developed during the architectural design of the buildings. In general, rooms along the perimeter of the site will require sound rated windo~vs. Units in Buildings 1 (the four east end units), 2 (the four east end units), 3 (the four east end units) and 4 (all units) along 1-680 would be exposed to levels over CNEL 65 dBA and ~vill require sound rated building constructions (xvindows and/or exterior walls) to meet the State Building Code requirement. All residential units in the project will require mechanical ventilation to allow the windows to be closed for noise control. An acoustical consultant should review the architectural design to be sure that the required treatments are incorporated into the construction documents. 11.3 Porches and decks exposed to a CNEL of 65 to 70 dBA ( Buildings 1, 2, 3, 4, 9 and 10) shall be partially enclosed or eliminated. A partial enclosure would consist of a solid six- foot tall balcony railing that ~vould act as a local noise barrier. Porches or decks exposed to levels greater than 70 dBA (Buildings 2, 3, 4, 9 and 10) shall be fully enclosed. A full enclosure would create a deck or porch that is similar to a sun room. It would be constructed out of standard building materials but need to provide adequate noise reduction. The enclosure could include operable windows or sliding glass doors so that the area can be open if the occupant desires. An acoustical consultant shall reviexv the design of the porch/deck treatments to confn'm that noise levels will achieve the City's goal. San Ramon Village Plaza Sfitigated Negative Declaration - Page 6 The sitting garden along 1-680 would be exposed to a future CNEL in excess of 75 dBA ~vhich is considered "clearly unacceptable" for residential development. To reduce noise at the outdoor use area and at Buildings 2, 3 and 4, the existing sound xvall could be extended an additional 275 feet. A ten-foot sound xvall would reduce the CNEL to less than 70 dBA ~vhich is considered to be "conditionally acceptable". It would be difficult to achieve the City's goal of CNEL 65 dBA at the sitting garden. Preliminary calculations indicate that the wall xvill need to be about 18 feet tall to meet the Cit3,,"s outdoor noise goal. Alternatively, a wall could be located immediately adjacent to the sitting garden to block freeway noise. The wall could be one to two feet shorter and achieve the same noise reduction. The exact height and composition can be determined during the detailed design phase. If there is a concern that the barrier would block viexvs, a clear barrier made of acrylic or glass could be used. An acoustical consultant shah review the design of the barrier to confmn that noise levels xvill achieve the Ci~7's goals. 11.4 The CiD' does not have a quantitative noise standard for mechanical equipment such as refrigeration units or air-conditioning systems. Noise generated by stationary sources (residential and retail) xvill need to meet, at a minimum, the performance standards contained in the Noise Element (CNEL of 60 dBA for residential uses). The mechanical design shall be reviewed by an acoustical consultant to verify that the City's standards x,411 be met and that the equipment will not significantly increase existing noise levels at residences and the common outdoor use area adjacent to the retail building. The mechanical and architectural plans should show all required sound attenuating features such as silencers and barriers. Residual Impact: Less than significant with mitigation measures. Impact: The project site plan would create vehicle conflicts. Mitigation Measures: 15.1 All outbound traffic at proposed project driveways on Bellina Street, Alcosta Boulevard and San Ramon Road shall be stop-sign controlled to avoid vehicle conflicts at these major ingress/egress points. 15.2 The majoritT of parking spaces located in the eastern (rear) portion of the site should be designated (18 total) for employee parking. This xvould maximize access for retail patrons to the majority of par-king spaces in the main retail parking lot. It is recommended that the proposed handicapped parking space in the rear retail parking field be relocated adjacent to the handicapped parking space proposed in front of the retail building on Bellina Commons (i.e. the southwest corner of the building). 15.3 The San Ramon Road limited access driveway shall have additional traffic controls to prevent potential vehicle conflicts for both inbound and internal motorists. Two additional stop-signs shall be installed in conjunction with this drivexvay to allow for safe access to the north-south Shell Gas Station easement. It is recommended that a stop-sign be installed for westbound traffic at the internal drive aisles' intersection with the north-south easement. Another stop-sign shall be installed for southbound traffic on the north-south Shell Gas San Ramon Village Plaza Mitigated Negative Declaration - Page 7 Station easement just prior to the outbound traffic flow lane to San Ramon Road. This will prevent internally circulating vehicles from interfering xvith inbound traffic. 15.4 Remove three diagonal retail parking spaces to prevent conflicts xvith through-traffic within the retail center. On the one-way eastbound retail par-king drive aisle, the first diagonal parking on the south entering from San Ramon Drive shah be removed. On the one-way xvestbound retail parking drive aisle, the first diagonal on the south shall be removed. Similarly, the first parking space on the east side entering from Bellina Street should be removed for traffic purposes. Removal of these spaces ~vill not change the project parking demand conclusions. 15.5 The parallel curb at the south end of Building 8 shall be painted red to prevent parked vehicles from bloc'king garage access to the last units in Building 7. 15.6 The main internal intersections in the retail and residential areas shall provide adequate truck turning radii for fn:e and garbage trucks. 15.7 Traffic calming measures as required by the CiuT Engineer shall be installed on the main north-south internal drive (Belhna Commons) betxveen Bellina Street and Alcosta Boulevard. Such measures could include, but are not limited to, speed tables. Finding: The project xvould not result in a significant increase in traffic.

ENVIRONMENTAL ISSUES Potentially s~gnificant Potentially Unless Less Than Significant Mit~afion S~?ificant No Impact Incorporated impact Impact 1. AESTHETICS. Would the project: a) Have a substantial adverse effect on a scenic xssta? [] [] [] [] b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? c) Substantially degrade the existing visual character or quali~, of the site and its surroundings? d) Create a new source of substantial light or [] [] [] [] glare, which would adversely a£fect day or mghttime mews in the area? Discussion: The proposed project would not result in significant adverse impacts to visual resources. A brief discussion of each environmental topic included under Section I is presented below. a) The project site is not witNin a designated scenic xdsta or scenic highway. Project development would not obstruct any scenic xdews. b) The project site is developed with retail buildings and parking lots. Street trees are located along the entire San Ramon Road frontage, along the Belhna Street frontage; and groups of trees are located along the easterly boundau~ of the site and dispersed throughout the existing parking lot on the westerly portion of the site. Project development would remove 28, or about 60 percent, of the existing trees. None of the trees planned for removal are "Heritage Trees" as defined in the Ci~"s Tree Ordinance. Of these, ten are located in the parking lot and the remaining 18 trees are located along San Ramon Road, Bellina Street and 1-680. Eight of the 11 street trees along San Ramon Road would be retained. Of the six trees along Bellma Street, five would be removed. Ten of the 18 trees along 1-680 would be removed. Plantings of new street trees along the southerly and westerly project boundaries, combined with a proposed hedge would provide adequate screening. The project would include new trees throughout the retail parking areas and the residential development. The proposed planting of trees along the easterly boundary would screen views of 1-680 from the project site. Project development would not degrade scenic resources at the project site. c) Generally, project development would improve the visual appearance of the project site. Currently the project site contains two single stor5' buildings that house small retail shops and restaurants and a large retail store. The buildings are in need of painting and repair. Landscaping is limited to trees located along the westerly', southerly and easterly site boundaries and trees scattered in the parking San Ramon Village Plaza Initial Study lot. The proposed pr.oject would renovate one of the buildings containing small retail shops and restaurants. The new building roofline would increase the height of portions of the building. New signage, fagade treatments, lighting and plantings would improve the visual appearance of the building. The other building containing retail shops and the larger structure would be demolished and replaced with the proposed residential development. Extensive landscaping including trees, hedges, plantings and open space areas would increase the amount of green space at the project site. Outdoor night lighting currently exists at the project site including light fixtures in the parking lot and building signage. The amount of outdoor lighting would increase over what is currently in use because of the increase in development at the site. However, the project landscaping would screen most of the night lights from view, especially along San Ramon Road and Bellina Street (where residential development is located). Night hghtmg and glare would not significantly increase as a result of the project. Miti~tion Measures. None required. Finding: Project development would not have an adverse affect on the visual character and quality of the site and surrounding area. Potentially S~gnifieant Pmennally Unless Less Than Stgn~qcant Mitiganon Significant No Impact Incorporated lmpact lmpact AGRICULTURAL RESOURCES. In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the Cahfomia Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the Cal/fomia Dept. of Conserwation as an ophonal model to use in assessing impacts on agriculture and farmland. Would the project: Convert Prime Farmland, Unique Farmland, or Farmland of Statew/de Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the Cahfomia Resources Agency, to non-agricultural use? b) Conflict w/th existing zoning for agricultural use, or a XWilliamson Act contract?

Where available, the significance criteria established by the applicable air quah~, management or air pollution control district may be relied upon to make the following determinations. Would the project: a) Conflict with or obstruct implementation of the applicable air qualin/plan? b) Violate any ak qualit3' standard or contribute substantially to an existing or projected ak quality. violation? c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is nonattainment under an applicable federal or state ambient air quality standard (including releasing emissions, which exceed quantitative thresholds for ozone precursors)? d) Expose sensitive receptors to substantial pollutant e) Create objectionable odors affecting a substantial number of people? Discussion: The proposed project would result in less than significant operational air quality impacts. Potent/ally significant impacts due to construction activities could occur. The recommended mitigation measures would reduce potentially significant construction air quality impacts to a less than significant level A brief discussion of each environmental topic included under Section 3 is presented below. a) The project would not conflict with the Bay ,&rea Air 2000 Clean Air Plan ,(]3AAQMD 2000). San Ramon Village Plaza Initial Study - 12 b) Local Climate The project is within the Ihvermore Valley. The Livermore Valley forms a small sub-reg/onal air basin distract from the larger San Francisco B%, Area Air Basin. The Livermore Valley air basin is surrounded on all sides by high hills or mountains. Significant breaks in the hills surrounding the air basin are Niles Canyon and the San Ramon Valley, which extends northward into Contra Costa Count3.'. The terrain of the Livermore Valley influences both the climate and air pollution potential of the sub-regional air basin. As an inland, protected valley, the area has generally lighter winds and a higher frequency of calm conditions when compared to the greater Bay Area. The occurrence of episodes of tzigh atmospheric stabiliu,, known as inversion conditions, severely limits the ability of the atmosphere to disperse pollutants vertically. Inversions can be found during ali seasons in the Bay Area, but are particularly prevalent in the'summer months when they are present about 90 percent of the time in both morning and afternoon. According to the Bay Area Air QuahU, Management District, mr pollution potential is high in the Livermore Valley, especially for ozone in the summer and fall. High temperatures increase the potential for ozone. The valley traps locally generated pollutants and is often the receptor of ozone and ozone precursors from upwind portions of the greater Bay Area. Transport of pollutants also occurs between the L/vermore Valley and the San Joaquin Valley to the east. During the winter, the sheltering effect of terrain and its inland location results in frequent surface based inversions. Under these conditions, pollutants such as carbon monoxide from automobiles and particulate matter generated by fireplaces and agricultural burning can become concentrated. Ambient Air Quality. Standards Both the U. S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) have established ambient air quality standards for common pollutants. These ambient air quahty standards are levels of contaminants which represent safe levels that avoid specific adverse health effects associated with each pollutant. The federal and state ambient standards were developed independently with differing purposes and methods, although both federal and state standards are intended to avoid health related effects. As a result, the federal and state standards differ in some cases. In general, the California state standards are more stringent. This is particularly true for ozone and PM~0. Federal Air Quality Standards The 1977 Federal Clean Air Act requires the U.S. Environmental Protection Agency, (EPA) to identi~, National Ambient Air Quality Standards (NAAQS) to protect public health and welfare. NAAQS have been established for the six "criteria" air pollutants. These criteria pollutants include ozone (O3), carbon monoxide (CO), nitrogen d/oxide (NO2), sulfur d/oxide (SO2), suspended particulate matter (PM~0), and lead (Pb). EPA pubhshes criteria documents to justify the cho/ce of standards. Standards for these pollutants are Listed in Table 2. These standards represent the levels of air quah~, necessary, with an adequate margin of safety, to protect the public health and welfare. In June 1997, the EPA adopted new national air quality standards for ground level ozone and for fine particulate matter. The EPA intends to phase out the 1-hour ozone standard of 0.12 parts per million (PPM) and replace it with an 8-hour standard of 0.08 PPM. The EPA also adopted an additional standard for particulate matter less than 2.5 microns in diameter (PMz.s). Although currendy in effect, the planning process to determine compliance with these new standards and the development of control programs to meet these standards, if needed, are several years away since a monitoring network has to be established and a minimum 3-vear monitoring period is required to determine designations. San l~mon Village Plaza Initial Study - 13 Implementation of the new standards has been further complicated by a recent court decision. On May 14, 1999, the Court of Appeals for the District of Columbia Circuit ruled that the application of ~he Clean Air Act, in setting the new public health standards for ozone and particulate matter, was an improper delegation of leg/slafive authority to the EPA, and thus unconstitutional. The decision was appealed to the Supreme Court and on February 27, 2001 the Supreme Court unanimously ruled in favor of the EPA, clearing the way for implementation of the new standards. State Air Quality Standards The 1988 Califomia Clean Air Act estabhshed state standards for criteria pollutants, which are also identified in Table 2. These standards are referred to as State Ambient Air Quality Standards (SAAQS), and are equal to, or more stringent than, their NAAQS counterparts. SAAQS have also been established for certain pollutants not covered by the N2M~QS, such as hydrogen sulfide and vinyl chloride. Bay Area Air Basin Attainment Status The project is within the nine count3' Bay Area ~5Jz Basin. Pursuant to 1990 amendments to the federal Clean Air Act and the California Clean Air Act of 1988, the EPA and CAP,_B have designated alt basins within the state where the federal or state ambient air quality standards are not met as "nonattainment areas", based on comphance with NAAQS and SAAQS standards. Because of the differences between the federal and state standards, the designation of nonattainment areas is different under the federal and state legislation. Air basins may be either attainment or non-attainment for each criteria air pollutant. Under the federal Clean Air Act, the Bay Area is currently considered a nonattainment area for the federal 1- hour ozone standard and a nonattamment area for ozone and PMw under the California Clean Air Act, CA1LB has developed recommended designations for California air basins, proposing that the Bay Area be designated as nonattainment for the new EPA 8-hour ozone standards. Levels of PMw at the Livermore monitoring site (the monitoring site nearest Dublin) meet the federal ambient standards but exceed the more stringent state standard. When it passed the CaLifornia Clean Air Act in 1988, the California Legislature recognized the relative intractabili ,ty of the PMw problem with respect to the state ambient standard and excluded it from the basic planning requirements of the Act. The Act did require the CARB to prepare a report to the Legislature regarding the prospect of achieving the State ambient air quality standard for PMw. This report recommended a menu of actions, but did not recommend imposing a planning process similar to that for ozone or other pollutants for achievement of the standard within a certain period of time. In addition, a region can be designated non-attainment, transitional or unclassified. The transitional designation recogmZes a region's improving air quality, but still maintains some regulatory restrictions and obhgations. The unclassified designation is given for a region where data is absent or too limited for designation. California Clean Air Act requirements include annual emission reductions, increased development and use of low emission vehicles, and the submittal of air quality attainment plans by air districts. Bay Area Air Quality Management District The Bay Area Air Quails,, Management District (BAAQMD) operates a network of air quahty monitoring sites in the region, including one in central Livermore on Old First Street. Table 3 shows a three year summary, of air quality data for the Livermore monitoring site for the period 2000-2002. Data are shown for ozone, carbon monoxide, nitrogen dioxide and PMw. The number of days exceeding each standard is shown for each year.

Table 3 shows that concentrations of carbon monoxide and nitrogen dioxide at the Liverrnore monitoring site meet state/federal standards. Ozone concentrations exceed both the state and federal standards, and exkibit wide variations from year to year related to meteorological conditions. Years where the summer months tend to be warmer than average tend to have higher average ozone concentrations while years with cooler than average temperatures tend to have lower average ozone concentrations. The federal Clean Air Act Amendments of 1970 established national ambient air qual2ty standards (.~QS), and individual states retained the option to adopt standards that are more stringent and to include other potlufion sources. California had already established irs own air quality, standards when federal standards were established. Because of the unique meteorological problems in the San Ramon Village Plaza Initial Study - 15 state, there is considerable diversiu, between state (SAAQS) and federal (NAAQS) standards currendy in effect in California, as shown in Table 2. The ambient air qualiU, standards are intended to protect the pubic health and welfare, and they incorporate an adequate margin of safety. They are designed to protect those segments of the pubic most susceptible to respiratou distress, known as "sensitive receptors", including asthmatics, the ve~ young, the elderly, people weak from other illness or disease, or persons engaged in strenuous work or exercise. Healthy adults can tolerate occasional exposure to air pollution levels somewhat above the ambient air qualit3' standards before adverse health effects are observed. The Bay Area BAr Quait3, Management District O,5_AQMD) operates a regional monitoring network which measures the ambient concentrations of six criteria air pollutants: ozone, carbon mono.ride, small diameter particulate matter (PM-10), lead, nitrogen dioxide, and sulfur dioxide. Monitoring for ultra-small diameter particulate matter (PM-2.5) began in 1999 using the federal reference method monitoring procedures. Sensitive Receptors BAAQlXID defines sensitive receptors as facilities where sensitive receptor population groups (children, the elderly, the acutely ill and the chronically ill) are likely to be located. These land uses include residences, schools, playgrounds, child care centers, retirement homes, convalescent homes and hospitals. The nearest sensitive receptors to the project site are homes located to the south of the project site and to the east across San Ramon Road.

If a project exceeds the thresholds, detailed air quality, analyses are usually required. If the project does not exceed the thresholds, it is typically assumed to liave a less than significant impact on air quahv. BAAQMD gener~y does not recommend a detailed air quality analysis for projects generating less than 2,000 vehicle trips per day. The proposed project would generate 970 vehicle trips per day, thus, a detailed air qualit3' analysis is not warranted. The project would not expose the pubic to sources of toxic air contaminants or odors. Thus, the project would fall below the B,5)xQMD thresholds for significant air qualit7 impacts and is not considered a project that could cause an adverse air quaiiu- impact. San Ramon Village Plaza Initial Study - 16 Construction Impacts Temporary construction activities may impact air qualiq,, but such impacts are highly variable from day-to-day depending on the type of construction activiq,. The BAAQIvlD has therefore developed a menu of mitigation measures, which if fully implemented, are presumed to achieve a less than significant air quality impact. The range of mitigation measures includes a set of "Basic Control Measures" and "Enhanced Control Measures" if the project construction area exceeds four acres. Because the project site is larger than four acres in size, enhanced dust control measures will be required during construction. With implementation of these measures, dust emission impacts during construction would be tess than significant. The project would not result in significant cumulative net increases in criteria pollutants. The project would generate less than 2,000 daily vehicle trips and, thus, is below the significance threshold. The project would not generate odors, toxics or have the potential for accidental releases of toxics. The project would require a general plan amendment on 3.15 acres of the project site changing the land use from Retail/Office to Medium-High Densiu? residential. The proposed project would not result in significant land use changes that would affect the growth assumed for the cit-),- in the Clean Air Plan (CAP) nor would it adversely affect the passenger vehicle trips and miles traveled (VMT). Sensitive receptors in the project area include residential area. Residential uses are considered more sensitive to air qualiu~ conditions than commercial and retail areas because people generally spend longer periods of time at their residences, resulting in greater exposure to ambient air quahU, conditions. Project operations would not expose the nearby sensitive receptors to significant pollutant concentrations. However, during construction activities, sensitive receptors could be exposed to high levels of dust emissions. With implementation of the recommended mitigation measures, dust emission impacts would be less than significant. e) The project would not create any objectionable odors. Mitigation Measures: 3.1 Construction contractors shall be required to water all active earth construction areas at least twice daily. 3.2 Construction contractors shall be required to cover all trucks hauling soil, sand and other loose materials or require all trucks to maintain at least two feet of freeboard. 3.3 Construction contractors shall be required to sweep dally (preferably with water sweepers) all paved access roads, parking areas and staging areas at construction sites. 3.4 If visible soil material is carried onto adjacent public streets, require construction contractor to sweep streets daily. 3.5 Construction contractor shall be required to enclose, cover or apply (non-toxic) soil binders to exposed stockpiles (dirt, sand, etc.). 3.6 Construction contractor shalI be required to install sandbags or other erosion control measures identified in the project's Storm Water Pollution Prevention Plan. San Ramon Village Plaza Imtial Study - 17 Finding: According to the current BAAQMED CEQA guidelines, the recommended mitigation measures would reduce construction period air quality impacts to a less than significant level.

Interfere substantially with the movement of any native resident or migratou, fish or wildlife species or with established native resident or migrator3.' wildlife corridors, or impede the use of nafve wildlife nursery. sites? Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Commumt3, Conservation Plan, or other approved local, regional, or state habitat conservation plan? Discussion: The proposed proiect would not result in significant adverse impacts to biological resources. A brief discussion of each environmental topic included under Section 4 is presented below. The project site is currendy developed with buildings and a parking lot. Existing trees were planted when the site was developed. Project development would not adversely affect candidate, sensitive or spedal status species. b) There is no riparian habitat located on the project site. A Zone 7 concrete lined canal is located off site adjacent to the southerly project boundao'. Project development would not affect the canal. San Kamon Village Plaza Initial Study - 18 c) There are no wetland areas on the project site. d) Project development would not substantially interfere with the movement of migratory fish and wildlife. e) Project development would result in the removal of approximately 27 trees. None of the trees planned for removal are "Heritage Trees" as defined in the Ci~"s Tree Ordinance. The project landscape plan proposes extensive tree planting including redwoods and oaks. The proposed landscape plan shows the number of replacement trees to be greater than the 27 trees to be removed. f) The project would not interfere with any adopted habitat consert'afion plans, natural community conse~-ation plans or other conservation plans. Mitigation Measures: None required. Finding: The project would not adversely affect biological resources.

Would the project: ~) Cause a substantial adverse change in the sigtuficance of a historical resotztce as defined in ~15064.57 b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to 915064.5? d) Directly or indirectly destroy a unique paleontologncal resource or site or unique geologic feature? Disturb any human remains, including those interred outside of formal cemeteries? Discussion: The proposed project would not result in significant adverse impacts to known cultural resources. In the event unknown cultural resources are discovered on site during earth moving activities, the recommended mitigation measures would reduce potential impacts to unknown cultural resources to a less than significant level. A brief discussion of each environmental topic included under Section 5 is presented below. a) The project site contains a 1970's era shopping center. There are no buildings on site that are considered kistorical resources as defined in Secuon 15064.5. b) There are no known archaeological resources present on the project site. c) There are no known palentological resources present on site. d) Project development would not disturb any known human remains. San Ramon Village Plaza Initial Study - t9 Mitigation Measures: Should any cultural materials or human remains be exposed or discovered during earth moving activities, the following mitigation measures shall be implemented: 5.1 Operations shall stop within 100 feet of the fred and a qualified professional archaeologist shall be contacted for further review and recommendations. 5.2 If human remains are discovered, the Alameda Coun .ty Coroner shall be notified. The Coroner would determine whether or not the remains were Native American. If the Coroner determines the remains are not subject to his authoriu,, the Nar/ve American Heritage Commission will be notified, who would attempt to identify descendants of the deceased Native American. 5.3 If the Community Development Director finds that the archaeological f'md is not a significant resource, work would resume only after the submittal of a preliminary, archaeological report and after provision for reburial and ongoing monitoring accepted. Provisions for identifying descendants of a deceased Native American and for reburial would follow the protocol set forth in the CEQA Guidelines. If the site is found to be a significant archaeological site, a mitigation program will be prepared and submitted to the Community Development Director for consideration and approval in conformance ,afth the protocol set forth in the CEQA Guidelines. Finding: Project development would not adversely affect and known cultural resources. 6. GEOLOGY AND SOILS.

Discussion: The Geotechnica/Investigation on Oliver Prope¢, prepared by Terrasearch, Inc. (2002) and Rep0r/on PreziminaD, Geoph_ysica/Investigation prepared by National Environmental, Inc. were used in analyzing potential impacts. Based on the geotechnical investigation, the project site is subject to strong seismic ground shaking. The recommended mitigation measures would reduce potent/ally significant impacts. A brief discussion of each environmental topic included under Section 6 is presented below. a) The project site within the Coast Ranges geomorphic province, a belt of sedimentary, volcanic and metamorphic rocks, which extend from southern Cal/fornia to Oregon. The structural geology of the Coast Ranges is complex and dominated by transpressive stress concentrated along faults within the San Andreas Fault system. On the eastern portion of the San Francisco Bay, bedrock geology consists of sedimentaO' and metamorphic rocks ranging from Cretaceous through Quaternary, periods (up to 144 million years to present). The materials underl)4ng the project site are mapped as Late Pleistocene alluvium, which consists of weakly consolidated, slightly weathered, poorly sorted clay, silt, sand and gravel The Calaveras Fault lies approximately 500 feet west of the western property. [me and the eastern portion of the Alquist Priolo Special Studies Zone encroaches about ten feet onto the southwestern corner of the project site. A geophysical survey was conducted at the site to determine if any traces or splays of the Calaveras Fault were present in the subsurface of the site. The findings of the geophysical survey concluded that no identifiable traces of the Calaveras Fault, or any tectonic offset from splay or conjugate faults exist at the project site. The potential for liquefaction and differential compaction is negligible. Because of the relatively fiat site and the nature of the subsurface materials, the potential for landslide is remote. b) Although the project site is relatively flat, there is a potential for erosion during construction activities due to the nature of the subsurface materials. c) See Item a above. d) The near surface clay was found to be moderately expansive. e) Project development would be hooked up to the municipal sewer system. Mitigation Measure: 6.1 Implement the recommendations identified in the geotechnical investigation prepared by Terrasearch, Inc. (2002). San Ramon Village Plaza Initial Stud}, - 21 6.2 Any changes in grading or building design that would be significantly affected by geologic hazards or softs conditions, or in t-mm would significantly alter geologic or softs conditions, shall be accompanied by a re-anatvsis of those conditions. In addition, any conditions discovered during excavation or grading that significantly depart from the previously described geologic and soils setting shall be evaluated. Finding: With the incorporation of the recommended mitigation ml:asures into the project, the project would not expose persons or properS., to significant impacts associated with soil or geologic conditions on the project site. HAZARDS AND HAZARDOUS MATERIALS. Would the project involve: a) Create a significant hazard to the public or the emfironment through the routine transport, use, or disposal of hazardous materials? 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? c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? e) For a project located within an an'Port land use plan or, where such a plan has not been adopted, within v, vo m/les of a publ/c an'Port or public use aixport, would the project result in a safety hazard for people residing or working in the project area? g) For a project within the vicinity, of a private airstrip, would the project result in a safety hazard for people residing or working in the project area?

Discussion: This discussion is based on the Phase I Environmental Site Mssessment San Ramon Village P/a~a Dub/in California prepared by Rosewood Environmental Engineering (2002). Volatile organic compounds related to ckT cleaning operations are present in the soil and asbestos-containing materials may be present in the building. Recommended mitigahon measures would reduce potentially significant impacts to a less than s~nificant level A brief discussion of each environmental topic included under Section 7 is presented below. a) Site clean up activities would result in the transport of hazardous materials. See also Item b. b) A soil sampling and analysis program was conducted in 1998 to investigate the subsurface beneath and adjacent to a former dry.. cleaning operation at the project site. Sampling results indicated that volatile organic compounds related to diT cleaning operations were detected in soil samples at a two foot depth beneath the floor slab of the &T cleaners. With the exception of Vinyl Chloride, the concentrations were below the Commercial/Industrial Preliminary Remediation Goals 0PRGs) established by EPA Region IX as action level guidance at that time (1998). Vinyl Chloride concentrations exceeded the Commerdal/lndustrial PRGs. A conditional "No Further Action" letter was issued by the Bay Area Regional Water Qualit-y Control Board CRWQCB) based on the results of the soil sampling and analysis program conducted in 1998. The conditions required that the floor of the dr},,- cleaners be sealed to prevent off-gassing of the vinyl chloride into the building and that the floor sea] condition be inspected annually. This action permitted the ckT cleaner space to remain in operation as a commercial/office space without cleaning up the soil beneath the space. This work was reportedly performed, the vinyl floor tile removed and disposed as an asbestos-containing material. In 2002 the RWQCB was contacted regarding the conditions placed on the "No Further Action" letter and the implications if a residential use was developed on the site. The RWQCB stated that if a residential use is developed on the site, affected soil exceeding the Residential PRGs will have to be excavated from the site as a hazardous waste. There are no exisdng schools or planned school located with 0.25 mile of the project site. d) The project site is not included on the Department of Toxic Substance Control's site clean up list. (DTSC 2004). e) The project site is not located within the .Alameda County Airport Land Use Commission junsdiction f) The project site is not located within two miles of any private airstrip. g) The project site is not located along any of the CitT's designated evacuation routes. The project would not interfere w/th adopted emergency response and evacuation plans. h) The project site is within the ciw limits and surrounded by urban development. There are no wildland areas within the project vicmit7. San Ramon Village Plaza Initial Study - 23 Mitigation Measures: 7.1 Affected soil exceeding the Residential PRGS shall be excavated and removed from the site as hazardous waste. Once cleaned up, a human Health Risk Assessment shall be prepared to demonstrate that soil gas emanating from the site will not pose a health threat to future site residents. 7.2 A site Health and Safew Plan shall be prepared that documents the appropriate protocol for construcdon personnel that may come in contact with contaminated soils. 7.3 Prior to demohtion, the three roof sections of the building shall be sampled to determine if they contain asbestos. If it is determined asbestos is present, it shall be disposed of as a hazardous material. 7.4 Site clean up and remediation shall be required to meet all federal, state and local regulations. Finding: With incorporation of the recommended mitigation measures into the project, the project would not expose construction workers, occupants and visitors to significant harmful levels of hazardous materials. HYDROLOGY AND WATER QUALITY. Would the project: Violate any water quaht3' standards or waste discharge requirements? b) Substantially deplete groundwater supphes or interfere substantially w/th groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table (e.g., the production rate of pre-exismag nearby wells would drop to a level which would not support existing land uses or planned uses for which perrmts have been granted?) c) SubstantiaLly alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, m a manner, which would result in substantial erosion or siltation on- or off-site? d) e) Substantially alter the exis2ng drainage pattern of the site area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoffin a manner, which would result in flooding on- or off-site? Create or contribute runoffwatet which would exceed the capacity of existing or planned storm water drainage systems or provide substantial additional sources of polluted runoff?

[] Expose people or structures to a sigrfificant risk of loss, iniury or death involving flooding, including flooding as a result of the failure of a levee or dam? j) Inundation by seiche, tsunami, or mudflow? Discussion: Project construction activities could result in site erosion. The recommended mitigation measures would reduce potentially significant impacts to a less than significant level. A brief discussion of each environmental topic is presented below. b) c) e) The project could temporarily ~qolate water qualiD' standards or waste discharge requirements if adequate erosion control measures are not in place during construction. See Section 6 GeoloD, and Soils for a discussion of recommended mitigation measures to reduce the potential for increased erosion at the project site. The project would not affect the qual/ty or quantity, of the local groundwater table. Grading during project construction could compound and increase erosion on site. Increased erosion could result in the sedimentation of receiving waters ieadmg to a reduction in water quality. Project development could improve drainage conditions at the project site. Currendy, the site is covered with about 95 percent impermeable surface. The proposed project would cover about 62 percent of the site in impermeable surface. This could result in less surface runoff than with the ex/sting development at the site. The project storm drain system would include a 12-inch storm drain along the easterly perimeter of the properU, that would connect with the existing 12-inch storm drain and Zone 7 storm drain outfall and channel. A 18-inch storm drain located along Bellina Commons would connect with an existing 12- inch storm dram located along the southwester perimeter of the project site. The proposed storm drain improvements would be adequate. Project runoff is not expected to adversely affect the capadty of the current storm drain system. Other than potential pollutants caused by project construction (see Item 8d above) there is no project operation that would substantially degrade water qua[it),. The project site is not within a 100-year flood hazard area. See Item g above. The project site is not xxdthin the path of a levee or dam. San Ramon Village Plaza Initial Study - 25 The project site is not subject to inundation by seiche, tsunami or mudflow. The site is about 15 miles from the nearest major water body - San Francisco Bay. Mitigation Measures: 8.1 A Storm Water Pollution Prevention Plan shall be prepared in compliance with the NPDES permit included in the erosion control measures appropriate for the project. Design of these measures shall be updated each year prior ro September 30 and approved by the City Engineer. Finding: With incorporation of the recommended mitigation measures, the project would not violate any water qualiu? standards or waste discharge requirements. LAND USE PLANNING.

Discussion: a) Proiect development would not divide the estabhshed residential community in the project areas. The project would replace existing retail development with residential development at its southerly end provid&ng a land use transition bemTeen the new retail development and nearby single-family development. While the proposed residential development is a higher density, than nearby low density single-family development, it would be separated by a Zone 7 canal and Bellma Street. Project landscaping would screen the new town homes from residences along Bellma Street. Residential development to the west is separated from the project site by San Ramon Road. b) The project would not conflict with applicable policies of the General Plan and Zoning Ordinance. A summary of project consistenu, is presented as Exh/bit A. c) The project would not conflict with habitat conservation on natural community conservation plans. Iv[idgation Measures: None required.

No Discussion: The proposed project would not result in impacts to mineral resources. A brief discussion of each environmental topic included under Section 10 is presented below a) The project site does not contain any known mineral resources. b) The project site is not designated as a locally important mineral resources recovery site. Mitigation Measures: None required. Finding: Project development would not result in any impacts to known or designated mineral resources. NOISE.

For a project located within an an-Port land use plan or, where such a plan has not been adopted, within two San l~arnon Village Plaza Initial Study - 27 miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? Discussion: This discussion is based on the Environmental Noise Impact Mnaiysis for the San Ramon k'ih'aev P/aRa Project Dubx7e. C~1 (2004) prepared by Rosen Gotdberg & Der. The proposed project would result in tempora~ noise Wnpacts due to construction activities and residents would be exposed to noise levels in excess of Ciw standards. The recommended mitigation measures would reduce noise impacts to a less than sig~ficant level. A brief discussion of each environmental topic included under Section 11 is presented below. a) The major noise source that affects the project site is vehicular traffic on 1-680 and San Ramon Road. Project development would result in temporal' noise increases during construction and the introduction of a sensitive receptor (housing) adjacent to the 1-680 on-ramp and San Ramon Road. The future noise environment would include noise generated by construction activities, traffic, the project's mechanical equipment and the car wash at the nearby gas station. Ciw of Dublin Noise Standards The Dublin Noise Element of the General Plan contains a guiding policy to midgate traffic noise levels to those identified by Table 9.1 of the Noise Element. For residential development, a CNEL of 60 dBA or less is considered "normally acceptable"; a CNEL of 60 to 70 dBA is considered "conditionally acceptable" and requires that noise insulation features be included in the project design; a CNiEL of 70 to 75 dBA is considered "normally unacceptable"; and a CNEL of 75 to 85 dBA is considered "clearly unacceptable". The Ciw of Dublin does not have a quantitative goal for noise levels in residential outdoor use areas. 'IZhe General Plan does, however, idenfi~' a CNEL of 60 to 65 dBA as being "conditionally acceptable" for neighborhood parks. Based on this Ciu, standard and discussions with City staff, for purposes of this noise analysis, it was assumed a CNEL of 65 dBA is the maximum goal for noise in outdoor use areas. The Noise Element has implementing policies to help achieve the goal of mitigating traffic noise impacts. Policy H (of the Noise Element) apphes to the proposed project and states: "Review all multi-family development proposals within the projected 60 CNEL contour for compliance with noise standards (45 CNEL in any habitable room) as required by State law." The Noise Element allows project designers to use one or more of four available categories of mitigation measures: site planrnng, architectural layout, noise barriers or construction modifications to reduce noise impacts. Existing Noise Environment Vehicular traffic on 1-680 and San Ramon Road represent the major noise source affecting the project site. An existing sound wall along the 1-680 southbound on ramp (presumably built to reduce noise at the single-family subdivision to the south of the project site) extends onto the project site at its southeast comer. Noise measurements were made on the project site to quanti~~ the existing noise environment and included w¢o 84-hour noise measurements and five short term(15 minutes) measurements. The long term noise measurements recorded a CNEL 83dBA along ~-680 and CNEL 66dBA along San Ramon Road. The short-term noise measurements ranged from CNEL 61 dBA to 79 dBA. San Ramon Village Plaza Initial Study - 28 Future Noise Environment Construction Noise from construction could generate short term noise levels that are significantly in excess of existing noise levels on the site. Construction sounds include those from diesel powered vehicles, stationary compressors and regular hand tools. Construction equipment typically emits maximum sound levels of 80 to 90 dBA at 50 feet. Th/s is the separation between the closest residential structures and the proposed buildings. Therefore, these noise levels would occur when the noisiest construction activities are occurring at the south end of the site. This noise could interfere with speech communications or, if occurring in the early morning or weekends, with sleep. Construction noise could impact nearby residences. The Cid' does not have any quantitative standards for construction but it is likely that construction noise would be loud enough to cause activiw interference at the existing residential area to the south. This is considered a potentially sigxfificant impact. The project would result in a small decrease in the trips generated by the San Ramon Village Plaza site (see Section 15 Transportation/Circulation). During the PM peak hour a total of 68 vehicular trips are generated by existing retail businesses. With the project, there would be 63 vehicular trips during the PM peak hour, a reducdon of 5 vehicular trips. Project-generated traffic would not result m a significant noise increase in the project area. The Ci~, of Dublin does not have projections for future traffic volumes along San Rarnon Road or 1-680. Based on data from the Metropolitan Transportation Commission, traffic volumes along 1- 680 will approximately double by the year 2025. This corresponds to a three dBA increase in CNEL. This increase has been applied to the measured noise levels from the freeway and San Ramon Road. The future CNEL at the setback of proposed residential buildings along San Ramon Road will be 71 dBA at ground level of the west end units of Buildings 9 and 10. Along 1-680, the upper floors of the east end units of Buildings 2 and 3 would be exposed to a CNEL of 82 dBA. Future noise from I~680 and San Rarnon Road will exceed the City's "normally acceptable" noise level goal ora CNEL of 60 dBA at Buildings 1, 2, 3, 4, 5, 9 and 10. Noise levels at the site could reach up to a CNEL of 76 dBA along 1-680 and a CNEL of 71 dBA along San Ramon Road at ground level. Exposure of residential units along 1-680 and San Ramon Road to levels over the City's "normally acceptable" goal is considered a significant impact. There are two types of outdoor use areas proposed: common spaces at ground level (tot lot and two sitting gardens) and those associated with a specific residential unit (porch or balcony). Two of the common spaces, the sitting garden along Bellina Street (between Buildings 8 and 9) and the tot lot next to Building 2 would be exposed to noise levels within the City's goal. The third common space is a sitting garden adjacent to 1-680 that would be exposed to noise levels over the 65 dBA goal. Porches and/or decks in Buildings 1 (the four east end units), 2 (the four east end units), 3 (the four east end units), 4 (all units), 9 (the three west end units) and 10 (all units) would also be exposed to noise levels greater than a CNEL of 65 dBA. Exposure of outdoor use areas to noise levels over a CNEL of 65 dBA is considered a significant impact. Mechanical Equipment Other potential noise sources associated with this type of project include ak-conditioning equipment. Common residential air-conditioners generate a noise level of about 65 to 70 dBA at five feet. Since two of the buddings (Building 1 and Building 6) are approximately 40 feet from the San Ramon Village Plaza Initial Study - 29 backyard fence of the nearest existing residences, the noise levels would be up to 52 dBA. Other mechanical equipment such as pumps and heating, ventilation and air-conditioning (HVAC) would be associated with the retail uses. These have varying noise levels that are t3npically louder than residential equipment and would need to be evaluated as information is made available during the design process. Car Wash The two northernmost residential buildings (Building 10 and Building 11) would have a clear view of the carwash and have the most exposure to carwash noise. Based on noise measurements of another car wash in Dublin, noise levels inside these residences would reach a maximum of 41 dBA with windows open during the blower cycle, the noisiest part of the wash ~cle. Though the carwash might be audible indoors, it would not be expected to interfere with indoor activities such as speech communication. This is considered a less than significant impact. b) There are no known sources of groundborne vibration associated with the project. c) Since the project-generated increases in traffic noise are less than the threshold for a noticeable increase of three dBA, the increase in traffic noise would be less than significant. Construction noise could impact nearby existing and proposed uses. The City. does not have any quantitative standards for construction but it is likely that construction noise would be loud enough to cause activity interference at the ex/sting residential area to the south. This is a potentially significant h2pact. e) The project is not within two m/les of a public airport or public use airport. f) The project is not within the ¼ciniry of a private airstrip. M_icigation Measures: 11.1 Applicant shall prepare a ~-onsrruction noise mitigation plan. The plan shall include but not be limited to the following: · Construction phasing plan showing the duration of each phase and equipment to be used. · Location of stationary equipment. · Calculation of noise levels at nearest residences and noise sensitive retail spaces. · Name of construction noise coordinator that can be posted at the entry to the site. Person responsible for responding to complaints and enacting solutions. 11.2 Sound-rated building construction shall be used to achieve acceptable indoor noise levels as per the State Building Code and City's Noise Element. The spedfication of these treatments should be developed during the architectural design of the buildings, tn general, rooms along the perimeter of the site will require sound rated windows. Units in Buildings 1 (the four east end units), 2 (the four east end units), 3 (the four east end units) and 4 (ail units) along 1-680 would be exposed to levels over CNEL 65 dBA and will require sound rated building constructions (windows and/or exterior walls) to meet the State Building Code requirement. All residential units in the project will require mechanical ventilation to allow the windows to be ciosed for noise control. An acoustical consultant should review the architectural design to be sure that the required treatments are incorporated into the construction documents. 11.3 Porches and decks exposed to a CNEL of 65 to 70 dBA ( Buildings 1, 2, 3, 4, 9 and 10) shall be San Ramon Village Plaza Init/al Study - 30 partially enclosed or eliminated. A partial enclosure would consist of a solid six-foot tall balcony railing that would act as a local noise barrier. Porches or decks exposed to levels greater than 70 dBA (Buildings 2, 3, 4, 9 and 10) shall be fully enclosed. A full enclosure would create a deck or porch that is similar to a sun room. It would be constructed out of standard building materials but need to provide adequate noise reduction. The enclosure could include operable windows or sliding glass doors so that the area can be open if the occupant desires. An acoustical consultant shall review the design of the porch/deck treatments to confm-n that noise levels will achieve the City's goal. The sitting garden along 1-680 would be exposed tO a future CNEL in excess of 75 dBA which is considered "clearly unacceptable" for residential development. To reduce noise at the outdoor use area and at Buildings 2, 3 and 4, the existing sound wall could be extended an additional 275 feet. ten-foot sound wall would reduce the CNEL to less than 70 dBA which is considered to be "conditionally acceptable". It would be difficult to achieve the Ci~'s goal of CNEL 65 dBA at the sitting garden. Preliminary calculations indicate that the wall ,x411 need to be about 18 feet tall to meet the City's outdoor noise goal. Alternatively, a wall could be located immediately adjacent to the sitting garden to block freeway noise. The wall could be one to two feet shorter and ach/eve the same noise reduction. The exact height and composition can be determined during the detailed design phase. If there is a concern that the barrier would block views, a clear barrier made of acrylic or glass could be used. An acoustical consultant shall review the design of the barrier to confirm that noise levels will achieve the Ciu"s goals. 11.4 The Ci~ does not have a quantitative noise standard for mechanical equipment such as refrigeration un/ts or air-conditioning systems. Noise generated by stadonaU' sources (residential and retail) will need to meet, at a mum, the performance standards contained in the Noise Element (CNEL of 60 dBA for residential uses). The mechanical design shah be reviewed by an acoustical consultant to verify that the Ciu,'s standards will be met and that the equipment will not significantly increase existing noise levels at residences and the common outdoor use area adjacent to the retail building. The mechanical and architectural plans should show all required sound attenuating features such as silencers and barriers. Finding: With incorporation of the recommended mitigation measures into the project, the project would not expose residential neighbors and proiect residents to significant unacceptable noise levels.

Would the project: Induce substantial population growth in an area, either directly (for example, by proposing new homes and business) or indirectly (for example, through extension of roads or other infrastructure)? b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? c~ Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? Discussion: The project would result in an increase of 56 housing units in the project vicim~-. T'nis would contribute to the City's need for new housing. A brief discussion of each environmental topic included under Section 12 is presented below. c) Using the Ci~"s current estimate of the average household size of 2.65 persons per housing unit, a population increase of approximately 148 persons could result. The project site is an infill site and is currently served by existing city roadways and utilities. The project would create 56 new housing units, making a contribution the housing needs of Dublin. The project proposes seven below market rate housing units: two units would be available to qualified individuals w/th very, low incomes; one umt would be available to a qualified individual with a low income; and four units would be available to persons with moderate incomes. The project would be in compliance with the CitT's Inclusionary Ordinance. The project would replace existing retail space with new housing. This would result in an increase in the housing stock in Dublin. Mitigation Measures: None required. Finding: The project would not generate a significant increase in population. The project would increase the amount of housing in Dublin including seven below market rate housing units.

A brief discussion of each environmental topic included under Section t3 is presented below. a) F/re services are provided by the Alameda Count' Fire Department under contract to the City, of Dublin. Thirty, slx line personnel are assigned over three shifts to the City on three engine companies and one truck company. There are three fire stafons in Dublin: Stations 16, 17, and 18 (CiD, of Dublin web site: xv,xnx,.ci.dublm.ca.usL First response to the project site would come from Station 16 PAth second response from Station 17; the response time is approximately six to eight minutes (McMillan 2004). AIl project buildings would be required to include sprinklers in comphance w/th the Uniform Building and Fire Codes as adopted by the City of DubLin. While project development would replace a portion of the existing retail development with new residential development, the project is not anticipated to adversely affect the Department's ability to respond to emergencies within the four to eight minute response dine. b) Police services are provided by; the Alameda County Sheriff's Office under contract to the City, of Dublin. Patrol, criminal investigation, crime prevent/on and business office functions are performed at the Department's business office located at 100 Civic Plaza (City of Dublin web site: www. ci.dublin.ca.us). c) Dublin Unified School District serves residents in Dublin. Children living in the new residential development at the project site would attend Dublin Elemental' School,, WeBs Middle School and DubLin H/gh School. Based on the District's student generation rates, approximately 35 school-age children could result from the project 0Dublin Unified School D/strict, 2004). d) The project proposes four primar3? open space/green space areas within the residential development including a resident's sitting garden with pubhc art at the comer of Bellma Street and San Ramon San Ramon \Tillage Plaza Initial Study - 33 Road, a lawn area at the southeasterly property boundar3,, a resident's sitting garden at the easterly prope~, bounda~, and a tot lot and la,xan area at the northeasterly portion of the residential development. These total approximately 7, 500 square feet. Access to the open space areas would be restricted to residents and their guests. A deck would be provided in each housing unit. As with other Dublin residents, project residents would be expected to use City and regional parks. The nearest Cit3' park is Shannon Park located south of the project site on San Ramon Road. The residential development is estimated to generate about 148 persons based on average household size in Dubhn. BThile some or all of these residents may use City parks, this potential increase is considered less than significant. e) The project would not adversely affect other public facilities.

Would the project: a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? b) Does the project include recreational facilities or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the em4ronment? Discussion: Project development would result in a potential increase in park and other recreational facilities. However, potential increases are expected to be less than significant. A brief discussion of each environmental topic included under Section 14 is presented below. a) The residential development portion of the project would increase the number of residents in Dublin, and it can be expected that these residents will use local and regional parks and other recreational facilities. The estimated population increase would not impose a significant increase in use of these facilities. See also Item d under Section 13 Public Services above. b) The project does not include active recreational facilities. A tot lot and two sitting gardens provide - open space areas for passive recreation. A pedestrian pathway system provides safe and convenient access to walk to the retail area of the project and throughout the residential areas. See also Item d under Section 13 Public Services above.

Would the proposal result m: a) Cause an increase m traffic, which is substantial m relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle traps, the volume to capaci~, ratio on roads, or congeshon at intersections? b) Exceed, either inddvidually or cumulatively, a level of ser~4ce standard established by the county congestion management agency for designated roads or highways? c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? d) e) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Result in inadequate emergency access? Result in inadequate parking capaci~'? g) Confi/ct with adopted policies, plans or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)? Discussion: The Focused Traffic Analysis for the Proposed San Ramon Village Plaza Development prepared b$' Omni Means (February 2004) was used in analyzing potential traffic impacts. Based on this a~alysis, the project would result in a decrease in PM peak hour vehicular raps. The proiect site plan would create potential circulation conflicts. A bt/el discussion of each env/ronmental topic included under Section 15 is presented below. a) The proposed project would result in a reduction in retail use and the introduction of residential use at the project site. To establish existing site trip generation, traffic counts were undertaken at the project sire during the ~¢I (7:00 - 9:00 am) and PM (4:00 - 6:00 pm) on May 1, 2003.

As shown in Table 2, the net change in AM and PM peak hour trips between the existing retail center and the proposed project would have a minimal effect on traffic flows and current levels of service at adjacent intersections. Thus, a comprehensive traffic analysis is not required for the project. Project generated traffic would not result in an increase in the level of service at nearby intersections. Project development would not affect existing or future air traffic patterns. The project site plan would create vehicle conflicts. San Ramon Road. The current driveway configuration at San Ramon Road may create vehicle conflicts between inbound patrons accessing internal parking aisles and those patrons · wishing to access the north-south Shell Gas Station easement. Conflicts also may result from patrons traveling through the westbound retail drive aisle and looping around to the eastbound drive aisle in search of a parking space could conflict with inbound vehicles from San Ramon Road traveling directly to the Shell Gas Station. Main North-South Internal Drive (Bellina Commons) between Alcosta Boulevard and Bellina Street. The wide travel width of 24 feet could encourage ("cut") through-traffic between the two public streets within the retail center as well as high vehicle speeds within the center. Truck Turning Radius. At the main internal intersections in the retail and residential areas, truck turning radii are not adequate for fzre and/or garbage truck access. Parking Conflicts. There is a potential for vehicles to parallel park along the curb at the south end of the drive aisle between Buildings 7 and 8, which would block residential access. The project site plan provides adequate emergency access in compliance with Police and Fire Department standards. The project proposes 93 parking spaces for retail use and 140 parking spaces for residential use for a total of total of 233 parking spaces. The project would be in conformance with the parking requirements for retai~ and residential use. San Ramon Village Plaza Initial Study - 36 The project site is currently served by Wheels Route 201(with limited services) and County Connection Route 121. The project would include a bus stop on San Ramon Road to the south of the project entrance. This would improve bus service for the project. M_idgadon Measures: 15.1 All outbound traffic at proposed project driveways on Bellina Street, Alcosta Boulevard and San Ramon Road shall be stop-sign controlled to avoid vehicle conflicts at these major ingress/egress points. 15.2 The major/t7 of parking spaces located in the eastern (rear) portion of the site should be designated (18 total) for employee parking. This would maximize access for retail patrons to the majority of parking spaces in the main retail parking lot. It is recommended that the proposed handicapped parking space in the rear retail parking field be relocated adjacent to the handicapped parking space proposed in front of the retail building on Bellina Commons (,i.e. the southwest corner of the building). 15.3 The San Ramon Road limited access driveway shall have additional traffic controls to prevent potential vehicle conflicts for both inbound and internal motorists. Two additional stop-signs shall be installed in conjunction with this driveway to allow for safe access to the north-south Shell Gas Station easement. It is recommended that a stop-sign be installed for westbound traffic at the internal drive aisles' intersection with the north-south easement. Another stop- Ogn shall be installed for southbound traffic on the north-south Shell Gas Station easement just prior to the outbound traffic flow lane to San Ramon Road. This will prevent internally circulating vehicles from interfermg with inbound traffic. 15.4 Remove three diagonal retail parking spaces to prevent conflicts with through-traffic within the retail center. On the one-way eastbound retail parking drive aisle, the first diagonal parking on the south entering from San Ramon Drive shall be removed. On the one-way westbound retail parking drive aisle, the first diagonal on the south shall be removed. Similarly, the first parking space on the east side entering from BelLina Street should be removed for traffic purposes. Removal of these spaces will not change the project parking demand conclusions. 15.5 The paralld curb at the south end of Building 8 shall be painted red to prevent parked vehicles from blocking garage access to the last units in Building 7. 15.6 The main internal intersections in the retail and residential areas shall provide adequate truck turning radii for fire and garbage trucks. 15.7 Traffic calming measures as required by the Cit3,? ]Engineer shall be installed on the main north-south internal drive (Bellma Commons) between Bell_ina Street and Alcosta Boulevard. Such measures could include, but are not limited to, speed tables. Finding: The project would not result in a significant increase in traffic. San Ramon Village Plaza Initial Study - 37 16.

The SRWCB requires that a General Construction Activities Stormwater NPDES Permit be obtained for construction activity that results in the disturbance of an acre or more of land, and a stormwater pollution prevention plan (SWPPP) must be developed and implemented for the sited covered by the General Permit. Response to Comment 1.1. Comment noted. Standard Public Work Conditions of Approval and Mitigation Measure 8.1 (See Initial Study Page 25) for the project require that a Storm Water Pollution Prevention Plan shall be prepared in compliance with the NPDES permit included in the erosion control measures appropriate for the project. Design of these measures shall be updated each year prior to September 30 and approved by the City Engineer. 1.2 Comment: In reference to page 25 of the Initial Study, Paragraph 9, Land Use Planning, the discussion mentioned utilizing a Zone 7 flood control facility.and Bellina Street to separate the existing low density residential uses from the project's proposed high density-residential uses. We reiterate our request from the Janua~, 23 letter for an access easement along the north side of the channel, or a 20-foot wide access easement through a private street near the southeast comer of the parcel. As also mentioned in the January 23 letter, the proposed plan does not provide any vehicle access from the north or south banks of the channel to allow routine inspection or maintenance. An existing access gate in the southeast comer of the development is presently used to access the channel for maintenance purposes. Continued access to this gate is necessaDf for Zone 7 to maintain its facility. Response to Comment 1.2: Conditions of approval of the Vesting Tentative Map require that the Developer shall provide a 3-foot wide gate with pedestrian access at the east end of the proposed wrought iron fence along the Alameda County drainage channel. Either through an easement or agreement with Zone 7 the Developer shall be required to provide pedestrian access to the gate to allow continued access by Zone 7 maintenance of the channel. The new wrought iron fence shall be installed by the applicant and its maintenance shall be the responsibility of the Homeowners Association.

We offer cmrunents in the following speciSc areas of interest: Water Supply: There are no existing or proposed future Zone 7 water supply facilities at the project site. Please contact Jaime Rios at extension 407 if you have may questions regarding water supply issues. Groundwater Management: Our records indicate there are no water wells or monitoring wells located within the project boundaries. 1£ any wells are found widxin the project lm~its, they should be reported to Zone 7. All unused or "abandoned" wells taus? be properly destroyed, or a si~ned "Statement of Future Well Use" must be filed at Zone 7 if there are plans to use the well in the future. Any plarmed new well, soil boring or well destruction must be pemzitted by Zone 7 before starting the work. There are no fees for the Zone 7 drilling permits. Well permit applications can be obtained by contactins W),~,xan Hong at extension 235 or can be downloaded from our web site at wx~av, zone 7water, corn, Flood Control: Zone ? has a Flood Control facility, Line % 1, wi'rich runs along the southeast section of the parcel from Bellh~a Street to h~terstate 680. The improvement plans should show the channel location, as well as a cross-sect/on of the cham~el butted up against the properW. Under the cra-rent proposed plan, there is no vehicle access fi'om the north or south banks o£the channel. In the past, the existing parking lot was utilized to access the north bank o£the chmmel for normal and emergency maintenance work. Access was through an existing three-foot wide pedestriaz2 gate located in the southeast comer of the parcel. Zone 7 requests that an access easement be provided at one of'two locations: 1) a 20-foot wide access easement along the north side of the Ms. Deborah Ungo-McCom~ick, Corm'act Plmm~er Community Deveiopmem Department Ci~ of Dublin January 23, 2004 Page 2 channel be provided (southeast border), or 2) a 20-foot wide access easement through the private street toward the southeast comer 0fthe parcel. The access easement would typically be utilized for routine maintenance mad inspections. Maintenance of the chmmel is performed by manual labor, as heavy equipment carmot be utilized. Failure to provide an access easement will prohibit Zone 7 from adequately maintain/rig the facility. Please note on Sheet L-l, that an existing Zone 7 chahMirLk fence should be shown. The property lines and distances should be depicted in a cross-section view. The ~ading should be at least a tkree percent (3%) slope away from the charmel. Please also note that the proposed wrought iron fence does nor meet Zone 7 standards. If the fencing varies from Zone 7's stmadard fence of ~-feet h/~,., black, vinyt coated fencing, then Zone 7 wiI1 not be responsible for ~:he maintenm~ce of the fence. Mitigation for the creation of nsw impervious areas within the LJvemaore-Amador Valley is addressed th_rough the collection of Special Drainage A_rea 7-1 (SDA) drainage fees. Drainage fees are collected by the governing agency for new roads (upon application for approval of vesting tentative or final map) and buildmgs, dr/veways, etc. (upon application for building penmt). Fees may be due, dependent on pre-projeci conditions, and whether or not the new project proposes to add more impervious area thma what was already there. Pi ease contact Craig Mayfietd at extension 240 if you have any questions regarding Flood Conn'ol comments. For future submittals at this location, please refer to Zone 7 Referral No. 0z~-001.

The reporting or monitoring program must be adopted when a public agency makes its findings for~EIRs, Mitigated Negative Declarations or Negative Declarations so that the program can be made a condition of project approval in order to mitigate significant effects on the environment. The program must be designed to ensure compliance during project implementation to mitigate or avoid significant environmental effects. 1.2 Purpose This Mitigation Monitoring Program Checklist is designed to serve as a tool for the evaluation of project compliance with mitigation measures identified in the Mitigated Negative Declaration for the San Ramon Village Plaza project. This document will be used by the City of Dublin (City) to verify inclusion of required project design features and implementation of mitigation measures. The Checklist serves as a summary so the City, other public agencies and the communiD' can easily determine which measures have been comphed with. 2.0 MITIGATION MONITORING PROGRAM CHECKLIST The Mitigation Monitoring Program Checklist is proposed for monitoring the implementation of the mitigation measures contained in the Miugated Negative Declaration and listed in the attached checklist. The Cit3' should implement the monitoring program as follows: The Planning Manager, Deparrrnent of Community Development, is responsible for coordination of the monitoring program including the monitoring checklist. Each responsible individual or agency will be responsible for determining whether the applicable mitigation measures contained within the checklist have been complied with. Once all mitigation measures have been complied with, the responsible individual or agency, should submit a completed chec 'klist to the Planning Manager. 2an Ramon [/i//ae~e P/a~a Mitigation Monitoffn~ ]~roegram Check~s!
