The certified EIR consisted of a Draft EIR and Responses to Comments bound volumes, as well as an Addendum dated May 4, 1999, assessing a reduced development and project alternative. The City Council adopted Resolution No. 53-93 approving a General Plan Amendment and a Specific Plan for the reduced area alternative on May 10,1993. On August 22, 1994, the City Council adopted a second Addendum updating wastewater disposal plans for Eastern Dublin. For identified impacts that could not be mitigated to a less than significant level, the City Council adopted a Statement of Overriding Considerations. All previously adopted mitigation measures for development in Eastern Dublin, that are applicable to this Project, continue to apply to the proposed project. The Eastern Dublin EIR is incorporated herein by reference. The Eastern Dublin EIR evaluated the potential environmental effects of urbanizing Eastern Dublin over a 20 to 30 year period. Since certification ofthe EIR, many implementing projects such as Dublin Ranch have been proposed, relying to various degrees on the Program EIR. A subsequent Mitigated Negative Declaration was later approved for Planning Area H of Dublin Ranch in 2000 (SCH #99112040, PA 98-070) adopted by Dublin City Council Resolution No. 34-00 on February 15, 2000. The City of Dublin approved development of Planning Area H on February 15,2000. The approvals included a General Plan/Specific Plan Amendment and Planned Development rezoning/Stage 1 Development Plan for a combination of commercial and residential development. A Mitigated Negative Declaration was also adopted by the Dublin City Council Resolution No. 34-00 on February 15, 2000 for Dublin Ranch Planning Area H, 2000 (SCH #99112040, PA 98-070). This project included an amendment to the Dublin General Plan and Eastern Dublin Specific Plan to amend the land use designation for a 10.5 acre parcel (which lies within the project area for this project) to allow campus office and general commercial. The previous land use designation, General Commercial, was revised to allow a mix of uses, including General Commercial/Campus Office, to meet changing market conditions. The City Council Resolution No. 34-00 contained findings that the Project would have impacts associated with the development of the property that would be mitigated to a less than significant level with incorporation ofthe mitigation measures into the project. CEQA Addendum for Grafton Station Area H City of Dublin June 2006 Pro; ect The applicant has requested approval of an amendment to the Stage 1 Development Plan. The amendment is required to modify the gross acres stated in the development plan for this site. The increase is due to the re-alignment of Dublin Boulevard and a more accurate measurement of the site. The increase in gross floor area will also allow for an increase in floor area in order to maintain the Floor Area Ratio (FAR) which has been established for the site in the Eastern Dublin Specific Plan (.25). The actual gross acreage of the site is 29.2 acres which means that 318,000 square feet of commercial space can be constructed on the site with a .25 FAR. Although the proposal would increase the amount of commercial square footage on the site by 25,059 square feet (over what was estimated in the Stage I Development Plan), this number is consistent with the square footage estimated for general commercial in the Eastern Dublin Specific Plan for the Tassajara Gateway subarea, of which this site is part of. CEOA The State CEQA Guidelines provide guidance on the appropriate document for revisions to a previously certified EIR. Section 15162 requires the preparation of a Subsequent EIR if the lead agency determines, on the basis of substantial evidence in the light of the whole record, one or more of the following: a) Are there substantial changes to the Project involving new or more severe significant impacts? There are no substantial changes to the Project analyzed in the Eastern Dublin EIR or the Mitigated Negative Declaration for Planning Area H. The Project proposes to amend the Stage 1 Development Plan to reflect the actual gross acreage on the site. This would increase the amount of square footage that could be built on the property, however, the project would be built at an FAR of .25 which was studied in the Eastern Dublin EIR and the Mitigated Negative Declaration and the total amount of square footage that would be constructed is consistent with the overall types ofland uses and densities allowed in the Dublin General Plan and the Eastern Dublin Specific Plan. The Eastern Dublin EIR studied the development potential for the Tassajara Gateway subarea. The increase in square footage on the project site will fall within the development potential which was studied in the Eastern Dublin EIR. The increase in square footage will not reduce the square footage available to the Dublin Land Company parcel, based on an FAR of .25 (which is the FAR established in the Eastern Dublin Specific Plan). b) Are there substantial changes in the conditions which the Project is undertaken involving new or more significant impacts? There are no substantial changes in the conditions in the Eastern Dublin EIR or the 1999 Mitigated Negative CEQA Addendum for Grafton Station Area H City of Dublin 2 June 2006 Declaration. The Project will be required to adhere to all ofthe mitigation measures in both documents which apply to this Project. c) Is there new information of substantial importance, which was not known at the time of the previous EIR that shows the Project will have a significant effect not addressed in the previous EIR; or previous effects are more severe; or, previously infeasible mitigation measures are now feasible but the applicant declined to adopt them; or mitigation measures considerably differentfrom those in the previous EIR would substantially reduce significant effects but the applicant declines to adopt them? There is no new information showing a new or more significant effect. The proposed Project would be consistent with the Eastern Dublin Specific Plan and the Eastern Dublin EIR mitigation measures and the mitigation measures included in the 1999 Mitigated Negative Declaration. d) If no subsequent EIR level review is required, should a subsequent negative declaration be prepared? No additional review is required based on the Initial Study. The Initial Study concluded that the Project will not create any significant impacts other than those identified in the Eastern Dublin EIR and the 1999 Mitigated Negative Declaration. As discussed above, none of the conditions described in the CEQA Guidelines Section 15162 has occurred. Under such circumstances, Section 15164 requires the lead agency to prepare an addendum to a previously certified EIR if some changes or additions are necessary but none of the conditions described in Section 15162 calling for preparation of a subsequent EIR have occurred. An addendum to be prepared as described below: a) The lead agency or responsible agency shall prepare an addendum to a previously certified EIR if some changes or additions are necessary but none of the conditions described in Section 15162 calling for preparation of a subsequent EIR have occurred. b) An addendum to an adopted negative declaration may be prepared if only minor technical changes or additions are necessary or none ofthe conditions described in Section 15162 calling for the preparation of a subsequent EIR or negative declaration have occurred. c) An addendum need not be circulated for public review but can be included in or attached to the final EIR or adopted negative declaration. d) The decision making body shall consider the addendum with the final EIR or adopted negative declaration prior to making a decision on the project. e) A brief explanation of the decision not to prepare a subsequent EIR pursuant to Section 15162 should be included in an addendum to an EIR, the lead agency's findings on the project, or elsewhere in the record. The explanation must be supported by substantial evidence. CEQA Addendum for Grafton Station Area H City of Dublin 3 June 2006 The City of Dublin has determined that an Addendum is the appropriate CEQA review for the proposed Project. Prior to making this determination, the City reviewed the Eastern Dublin EIR and the previous Mitigated Negative Declaration for Planning Area H to determine if any further environmental review was required for the proposed Site Development Review and Stage I Development Plan amendment and Stage 2 Planned Development rezoning. This Addendum is adopted pursuant to CEQA Guidelines section 15164 based on the environmental checklist. The Addendum reviews the proposed additional square footage on the site, over what was reviewed in the Stage 1 Development Plan and 1999 Mitigated Negative Declaration. Through the adoption ofthis Addendum, the City has determined that the proposed changes do not require a subsequent EIR or negative declaration under Section 15162 of the CEQA Guidelines. The City further determines that the Eastern Dublin EIR and the 1999 Mitigated Negative Declaration adequately address the potential environmental impacts of the proposed project. Pursuant to Section 15164 ofthe CEQA Guidelines, the Addendum does not need to be circulated for public review. The environmental document will be considered with the prior environmental documents before making a decision on this project. The attached Initial Study, referenced Eastern Dublin EIR and the 1999 Mitigated Negative Declaration are all available for review in the Community development Department located in the Dublin City Hall at 100 Civic Plaza in Dublin.

Description of project: The Applicants have proposed amendment to the Stage I Development Plan to increase the approved square footage for the property from 292,941 square feet to 318,000 square feet, while maintaining a .25 Floor Area Ratio for a retail shopping center. The development will be constructed on 29.2 gross acres which is larger than the acreage estimated by the Stage 1 Development Plan which estimated that the gross acreage of the site was 26.9 acres (a difference of2.3 acres). The increase in gross floor area is due to the re-alignment of Dublin Boulevard, the inclusion of half ofthe street right-of way of North side Drive and a more accurate measurement of the parcels. CEQA Addendum for Grafton Station Area H City of Dublin 5 June 2006 The Project is consistent with the General Commercial and General Commercial/Campus Office land use designations of the General Plan and Eastern Dublin Specific Plan. The purpose ofthis project (an amendment to the Stage I Planned Development Zoning) is to construct a project which has an FAR of .25 which is the established FAR for this property. The Project will result in a commercial center which is 318,000 square feet in size, which is approximately 25,000 square feet larger than originally studied for this property. Although the Project will result in an increase of25,059 square feet of commercial floor area, the total amount of floor area proposed has been the subject of prior CEQA reviews, through the 1993 Eastern Dublin EIR with mitigation measures. All of the mitigation measures in the 1993 EIR continue to apply to this property including the Project. For the significant and unavoidable impacts, the City adopted a Statement of Overriding Considerations (Resolution 53-93) as part of the 1993 Eastern Dublin EIR. This Project also lies within Dublin Ranch Area H. In 1999, the City adopted a Mitigated Negative Declaration for the proposed Project which reviewed development on the property and looked at the approved conditions for the Eastern Dublin Specific Plan area. This amendment to the Stage 1 PD is also consistent with the Mitigated Negative Declaration adopted for Dublin Ranch Area H. 11. Surrounding land uses and setting: The project site is located in an area referred to as Planning Area H in Dublin Ranch within the Eastern Dublin Specific Plan Area. The subject property is approximately 29.2 gross acres. The subject property is located south of Dublin Boulevard, north ofI-580 and Northside Drive. The subject property is also located within the Tassajara Gateway subarea in the Eastern Dublin Specific Plan. 12. o.ther public agencies whose approval is required: (e.g., permits, financing approval, or participation agreement.)

CEQA Addendum for Grafton Station Area H City of Dublin 17 June 2006 Discussion of Checklist Legend PS: LS/M: LS: NI: Potentially Significant Less Than Significant After Mitigation Less Than Significant Impact No Impact The following information is provided for the environmental checklist. The discussions are summary only, the proper EIR and MND should be consulted for a full discussion of all of the impacts and mitigation measures. The discussion also examine whether the additional square footage of the commercial center would require preparation of a subsequent EIR, MND, or NO pursuant to CEQA Guidelines Section 15162. Because the Project does not propose a new development or square footage beyond what was originally studied for the Tassajara Gateway subarea of the Eastern Dublin Specific Plan, most impacts area unchanged for the Project. Finally, many of the prior impacts related to biology, soils, drainage and other similar terrain-related impacts no longer apply to the Project Area since the area has previously been rough graded. I. Aesthetics The project area is vacant and is relatively flat. The Eastern Dublin EIR classifies the project site as "valley grasslands." The Project site is located adjacent to 1-580 and is located south of Dublin Boulevard which is one of the City's major thoroughfares. The Eastern Dublin EIR contains a number of Mitigation Measures that are applicable to this project to assist in reducing aesthetic impacts to a less than significant level. The proposed project will not result in any new impacts other than those identified in the 1999 Mitigated Negative Declaration. The 1999 Mitigated Negative Declaration identified supplemental Mitigation Measure 1 that requires pole mounted streetlights to be equipped with cut-off lenses and oriented down toward interior streets to minimize unwanted glare spillover. Building security lights and all other lights shall also be directed downwards. Proiect Impacts a) Have a substantial adverse impact on a scenic vista? LS. Approval and construction ofthe proposed project would convert an existing vacant field, which was historically used for agricultural uses, to a commercial development. This impact was addressed in the Eastern Dublin EIR (Impact 3.8/F) and it was determined that no measures would reduce this impact to a less than significant level. The EIR concluded that this impact would be a potentially significant CEQA Addendum for Grafton Station Area H City of Dublin 18 June 2006 irreversible change and a Statement of Overriding Considerations has been approved for this impact. b) Substantially damage scenic resources, including state scenic highway? NI. The project site is located adjacent to the 1-580 freeway which is not a state scenic highway. c) Substantially degrade existing visual character or the quality of the site? LS. This impact was addressed in the Eastern Dublin EIR and a Statement of Overriding Considerations. d) Create light or glare? LS. This impact was addressed in the 1999 Mitigated Negative Declaration. The Mitigated Negative Declaration determined that any development on this project site could create undue glare on adjacent properties. Mitigation Measure I was incorporated into the project which reduced this impact to a less than significant level. Mitigation Measure 1 will also apply to the new project. Overall, no additional impacts to aesthetics (as identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration) are expected to occur as a result ofthis Project. II. Agricultural Resources The Eastern Dublin EIR notes that the project site does not have soils or prime or unique farmland. Additionally, the project site is not currently used for agricultural purposes and is not emolled in the Williamson Act. The Eastern Dublin EIR determined that the loss of agricultural land was significant and unavoidable. A Statement of Overriding Considerations was adopted to mitigate this impact to a less than significant level. Project Impacts a-c) Convert Prime Farmland, conflict with agricultural zoning or involve other changes which could result in conversion of farmland to a non-agricultural use? NI. As discussed above, although the site has been historically used for agricultural purposes, the site is currently vacant and is not considered prime farmland. No additional impacts to agricultural resources (as identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration) are expected to occur as a result of this Project. III. Air Quality Dublin is located in the Tri- Valley Air Basin. Within the Basin, state and federal standards for nitrogen dioxide, sulfur dioxide and lead are met. Standards for other airborne pollutants, including ozone, carbon monoxide and suspended particulate matter (PM-I 0) are not met in at least a portion of the Basin. CEQA Addendum for Grafton Station Area H City of Dublin 19 June 2006 Mitigation Measures 3.11/1.0 through 3.11/13.0 were included in the Eastern Dublin EIR to assist in reducing long-term and short-term air quality impacts. Impacts related to emissions from construction vehicles, mobile source emission of reactive organic gasses and nitrogen dioxide and stationary source emissions were identified as significant and unavoidable and a Statement of Overriding Conditioners were adopted by the City of Dublin for those impacts. The 1999 Mitigated Negative Declaration did not identify any new or supplemental impacts or mitigation measures from the Eastern Dublin EIR related to air quality. Project Impacts a) Would the project conflict or obstruct implementation of an air quality plan? LS. The proposed project would not conflict with the local Clean Air Plan adopted by the Bay Area Air Quality management District, since the proposed Project (proposed square footage of non-residential development) has been included in the Eastern Dublin Specific Plan. b) Would the project violate any air quality standards? LS. During the construction of the building and site improvements could result in exceedance of air quality standards due to dust and equipment emissions (Impact 3.lIA and B). The Project will be required to conform to Mitigation Measures 3.11/1.0 - 3.11/4.0. A Statement of Overriding Considerations was also adopted in the Eastern Dublin EIR because the EIR assumed that air quality impacts as a result of construction equipment could not be reduced to a less than significant impact. Similarly, potential air quality impacts related to mobile source emission of Reactive Organic Gasses and Nitrogen Oxide, both precursor indicators of smog, and stationary source emission were found to exceed regional air quality standards even with mitigation measures and were included in the Statement of Overriding Considerations (Eastern Dublin EIR Impacts 3.11/C and 3.11/E). c) Would the project result in cumulatively considerable air pollutants? LS. The Eastern Dublin EIR identifies Mobile Source Emissions and Stationary Source Emissions as significant irreversible impacts. These impacts are typically based on vehicular emission from future traffic as well as stationary sources. A Statement of Overriding Considerations was adopted for long-term impacts which has reduced this impact to a less than significant level. d) Would the project expose sensitive receptors to substantial pollutant concentrations? NI. The proposed Project includes commercial and some office uses, which are not considered sensitive receptors. The Project is located near some residential uses, however, the 1999 Mitigated Negative Declaration determined that non-residential development in Area H would not create any impacts on these residential uses. CEQA Addendum for Grafton Station Area H City of Dublin 20 June 2006 e) Would the project create objectionable odors? NI. The proposed Project includes typical retail, office and restaurant uses. The proposed type of development was studied in the 1999 Mitigated Negative Declaration and it was determined that commercial development would not create objectionable odors. Overall, no additional impacts to air quality (as identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration) are expected to occur as a result of this Project. IV. Biological Resources The Eastern Dublin EIR indicates that the Project area is dominated by non-native grassland and dryland-farmed (grain crops) habitats. A detailed biological investigation was completed by H.T. Harvey and Associates in conjunction with the 1999 Mitigated Negative declaration. A number of mitigation measures (Mitigation 3.7/1.0 to 3.7/28.0) are included in the Eastern Dublin EIR to reduce impacts to a less than significant level, except for the loss of botanically sensitive habitat. Plants Based on the history of cultivation of Planning Area H, in which the subject site is located, most of the 23 special-status plant species identified as potentially occurring in the project area are not expected to be present. Previous agricultural activities, including livestock grazing and crop production have degraded potential habitat for these species, and existing predominant plant species include invasive forbs and grasses indicative of disturbed habitants. Only one special-status plant species has been observed in Planning Area H. However, the San Joaquin spearscale (Atriplex joaquinana) has been observed in similar habitat on the parcel immediately east of Area H and it may occur in Area H as well. Animals The Eastern Dublin EIR and the 1999 Mitigated Negative Declaration provide background information on the potential for special-status and sensitive animals species that could potentially occur on the Project site. With the permitted grading on the Project site, many of these species are no longer expected to occur on the site. Wetlands The 1999 Mitigated Negative Declaration identified approximately 5.33 acres of wetlands in Planning Area H, a portion of which were on the subject property. In 2003, the United States Army Corps of Engineers issued a Section 404 Permit to the owners of the property. The wetlands area was then filled in according to the permit. Project Impacts a) Would the Project have a substantial adverse impact on a candidate, sensitive or special status species? LS. In accordance with the permit conditions of the United States Army Corps of Engineers (USACE) wetland fill permit (dated May 23, 2006) and the Regional Water Quality Control Board Water Quality Certification Order CEQA Addendum for Grafton Station Area H City of Dublin 21 June 2006 (dated April 16, 2003) the mitigation measures addressing impacts on candidate, sensitive or special status species have already been or are currently being implemented. As mentioned above, the site has already been filled in and graded in accordance with the permits. b,c) Would the Project have a substantial adverse impact on riparian habitat or federally protected wetlands? LS. A portion of the Project site was determined to have farmed wetlands, which is a type of Waters of the United States found on agricultural lands. In accordance with the approval conditions of the USACE wetland fill permit and Regional Water Quality Control Board Water Quality Certification Order mitigation measures addressing impacts on candidate, sensitive or special status species have already been or are currently being implemented. d) Would the Project interfere with movement of native fish or wildlife species? NI. The farmland wetlands have been filled in with the required permits. No significant wildlife movement occurs on or across the site and therefore it is not anticipated that the development will interfere with such actions. e,f) Would the Project conflict with local policies or ordinances protecting biological resources or any adopted Habitat Conservation Plans or Natural Community Conservation Plans? NI. No significant trees are present on the site and there are no trees on the site which meet the requirements for protection under the City's Heritage Tree Ordinance. The site is not located within the boundaries of any Habitat Conservation Plan. The increase in the amount of square footage of commercial development on the site will not impact the overall biological resources on the site as reviewed in the 1999 Mitigated Negative Declaration because the Declaration assumed full development of the site. Overall, no impacts to biological resources, not previously identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration for Area H, are expected to occur as a result of this Project. The project will be required to follow Mitigation Measures 2 and 3 of the 1999 Mitigated Negative Declaration, as well as the mitigation measures established in the Eastern Dublin EIR. V. Cultural Resources Eastern Dublin was surveyed in 1988 as part of the Eastern Dublin Specific Plan and Eastern Dublin EIR. In May of 1999 the project area was surveyed by Holman and Associates in conjunction with the 1999 Mitigated Negative Declaration. No potentially significant prehistoric or archeological materials or indicators were found on the property during the study. The 1999 Mitigated Negative Declaration incorporated Mitigation Measure 4 which requires the Project to include a contingency plan in the event that archeological or paleontological resources are found on the site. CEQA Addendum for Grafton Station Area H City of Dublin 22 June 2006 Project Impacts a) Would the Project cause substantial adverse changes to significant historic resources? NI. The Project site is vacant and no historic resources have been found the site. b, c) Would the Project cause a substantial adverse change in the significant or an archeological resource or destroy a paleontological resource or unique geological feature? NI. The site is relatively flat and does not have any unique geological features. The Eastern Dublin EIR identified several potential significant archeological resources in Eastern Dublin. There is a remote possibility that archeological or paleontological resources could be found on the site during construction and/or grading. The 1999 Mitigated Negative Declaration incorporated Mitigation Measure 4 which requires the Project to include a contingency plan in the event that archeological or paleontological resources are found on the site. This Mitigation Measure will be included in the revised project and the proposed Project will not change the impacts identified in the 1999 Mitigated Negative Declaration. d) Would the Project disturb any human remains? LS. There is a remote possibility that human remains could be uncovered on the site during construction. The 1999 Mitigated Negative Declaration required that the Project adhere to Mitigation Measure 4 to reduce these potential impacts to a less than significant level. The proposed Project will not result in any additional impacts to Cultural Resources other than those identified in the Eastern Dublin EIR and Mitigation Measure 4 in the 1999 Mitigated Negative Declaration. IV. Geology and Soils The information in this section is based on preliminary geotechnical reports cited in the 1999 Mitigated Negative Declaration and the letter by Berlogar Geotechnical Consultants (dated March 6, 2006). The reports and letter are on file with the City of Dublin. Mitigation Measures 3.6/1.0 - 3.6/2.0 and 3.6/6.0 - 3.6/8.0 ofthe Eastern Dublin EIR were adopted to reduce Impacts 3.6/A through 3.6/L to less than significant impacts, with the exception for impact 3.6/B regarding ground shaking which was significant and unavoidable (a Statement of Overriding Considerations was adopted for this impact). No additional mitigation measures were included in the 1999 Mitigated Negative Declaration. Seismic The Project area is part of the San Francisco Bay Area, a seismically active region. The Eastern Dublin EIR notes the presence of several nearby significant faults including the Calaveras Fault, Greenville Fault, Hayward Fault and the San Andreas Fault. The likelihood of a major seismic event on one or more of these faults in the near future is believed to be high. However, the site is not part of a Special Study Zone as identified by the State of CEQA Addendum for Grafton Station Area H City of Dublin 23 June 2006 California. Please refer to the 1999 Mitigated Negative Declaration for more background information. Site Soils Soils on the site are characterized as colluvium, which is highly expansive with a brittle layer of subsoil. Colluvium soil typically consists of dark gray, very stiff to hard silty clay. Landform and Topography The site has very little variation in topography and gently slopes upward from the south (adjacent to 1-580) to the north (adjacent to Dublin Boulevard). The lowest elevation is approximately 345 feet above sea level and the highest is 353 feet for a grade change of approximately 8 feet. Drainage The permitted grading eliminated a number of small, unmanned north-south intermittent streams that were described in prior CEQA reviews. Project Impacts a) Would the Project Expose people or structures to potential substantial adverse impacts, including loss, injury or death related to ground rupture, seismic ground shaking, groundfailure or landslides? LS. The Project site is subject to ground shaking caused by a number of regional faults. Under moderate to severe seismic events which are probable in the Bay Area, buildings, utilities and other improvements would be subject to damage caused by ground shaking. The Eastern Dublin EIR contains mitigation measures to reduce impacts related to ground shaking to a less than significant level. b) Is the site subject to substantial erosion and/or the loss of topsoil? LS. The Eastern Dublin EIR notes that construction of all of the land uses in the Eastern Dublin Specific Plan Area would increase erosion and sedimentation in the area through grading on the sites. Mitigation Measures 3.6/27.0 and 3.6/28.0, in the Eastern Dublin EIR, require the Project to prepare and implement interim erosion plans as part of the grading permits. c-d) Is the site located on soil that is unstable or expansive or result in landslides, liquefaction or collapse? LS. The site has colluvium soil which typically has a high shrink-swell potential. Mitigation Measures 3.6/14.0 through 3.6/16.0 were adopted in the Eastern Dublin Specific Plan to reduce the potential for shrink-swell impacts to a less than significant level by requiring appropriate structural foundations and other techniques to reduce the risk of structure and infrastructure damage. e) Does the Project site have soils incapable of supporting on-site septic tanks? NI. The Project will be connected to a sanitary sewer system provided by the Dublin San Ramon Services District and therefore septic tanks will not be used. CEQA Addendum for Grafton Station Area H City of Dublin 24 June 2006 Overall, no impacts to soils and geology not previously identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration are expected to occur as a result ofthe revised project. VI. Hazards and Hazardous Materials The Project site is vacant with no structures. Phase I and Phase 11 hazardous materials studies were conducted for Planning Area H in 1997 and determined that no hazardous materials were in the Area. Project Impacts A, b, c) Would the Project create a significant hazard to the public through the transport, use, disposal or emission of hazardous materials? LS. Proposed uses for the Project include retail, office and restaurant uses. Hazardous materials are not typically associated with these types of uses; however, minor quantities of hazardous materials could be associated with the uses. These materials could include lawn chemicals, cleaning solvents or other items typically used for building and site maintenance. Located near a school? D) Would the Project be located on a site which is included on a list of hazardous materials sites? NI. Studies conducted in the site indicate that the site is free of hazardous materials. E, f) If the site is located within an airport land use plan or within the vicinity of a private airstrip, would the Project result in a safety hazard for people working or residing in the area? NI. The Project area is located to the Northwest of the Livermore Municipal Airport. During an Alameda County Airport Land Use Commission (ALUC) meeting on April 14, 1999, the ALUC determined that the project area was outside ofthe referral area for the Livermore Municipal Airport. g) Would the proposed Project impair the implantation of the adopted emergency response plan or emergency evacuation plan? NI. Adequate emergency access will be provided in the area through collector streets. The proposed Project will not interfere with access to these streets as development was anticipated on this parcel in the Eastern Dublin Specific Plan and the 1999 Mitigated Negative Declaration. h) Would the proposed project expose people or structures to a significant risk of loss, injury or death involving wildlandfires? LS. The Project site is currently a vacant field with some grasses. Although the site is vacant, several projects near the project site are under construction which has reduced the amount of grasslands in the area. Development ofthe project site will include new waterlines, fire hydrants and emergency vehicle access easements for firefighting purposes as well as new fire stations and personnel in the Eastern Dublin Planning Area to meet the needs of the businesses and residences in the area. CEQA Addendum for Grafton Station Area H City of Dublin 25 June 2006 VIII. Hydrology and Water Quality. The project site is relatively flat, although the site has a higher elevation that the adjacent property due to rough grading and fill which was conducted in the past. Although the 1999 Mitigated Negative Declaration determined that a large portion ofthe site was located in Flood Zone AH, the Federal Emergency Management Agency (FEMA) has removed the property from a Special Flood Hazard Area. The new flood zone designation for this property is now Zone X which means outside a special flood hazard area. The 1999 Mitigated Negative Declaration included additional Mitigation Measure 5 which requires the preparation of a Stormwater Pollution Prevention Plan (SWPPP), Mitigation Measure 6 which requires a drainage and hydrology study and Mitigation Measure 7 which requires the applicant to submit proofthat the property is outside a flood hazard area in conjunction with the Building Permit(s). Proiect Impacts a) Would the Project violate any water quality standards or waste discharge requirements? LS. Construction of the Project would require grading in order to construct the building pads, roadways, utilities and other improvements. The 1999 Mitigated Negative Declaration included supplemental Mitigation Measure 5 which requires a Stormwater Pollution Prevention Plan be prepared to reduce potential water quality impacts. b) Would the Project substantially deplete groundwater recharge areas or lowering of water tables? LS. This impact has been addressed in the Eastern Dublin EIR and the project will be required to adhere to Mitigation Measures 3.5/49.0 and 3.9/50.0. The 1999 Mitigated Negative Declaration did not identify any additional impacts as a result of development on the site. c) Would the Project substantially deplete groundwater recharge areas or lowering of the water table? LS. The Eastern Dublin EIR acknowledges that the conversion of vacant land to urban uses will alter existing drainage patterns. Compliance with Mitigation Measure 5 in the 1999 Mitigated Negative Declaration will reduce erosion on the site from both construction and post construction to a less than significant level. The revised Project will be required to comply with this mitigation measure. d) Would the Project substantially alter drainage patterns or result in flooding on or off the project site? LS. Development of vacant properties in the Eastern Dublin Planning Area could alter drainage patterns on the project site. However, drainage will be altered through newly constructed underground pipes, culverts and similar facilities. e) Would the Project create stormwater runoff that would exceed the capacity of drainage systems or add substantial amounts of polluted runoff? LS. Construction CEQA Addendum for Grafton Station Area H City of Dublin 26 June 2006 of on-site improvements is anticipated to lead to greater quantities of stormwater runoff. The 1999 Mitigated Negative Declaration requires the project to prepare a SWPPP to reduce impacts on the site. Additionally, Mitigation Measure 6 requires the developer to submit a drainage and hydrology study to the Public Works Department prior to issuance of any grading permits. f) Would the Project substantially degrade water quality? LS. Mitigation Measure 5 requires that the developer create a SWPPP in order to minimize impacts on water quality as a result of erosion. g) Would the Project place housing within a 1 OO-year flood hazard area as mapped by a Floor Insurance Rate Map? NI. This project does not include housing units. h,i) Would the Project place within a 1 OO-year flood hazard boundary structures that impede or redirect flood floor, including dam failures? NI. No portion of the Project site is located within a flood hazard area as defined by the Federal Emergency Management Agency. j) Would the Project result in inundation by seiche, tsunami or mudflows? LS. The site is not located near a significant body of water which could result in a seiche. The risk of a potential mudflow is considered low since no historic mudflows or landslides have been identified on the site. The Eastern Dublin Specific Plan contains Mitigation Measures 3.6/17.0 and 3.6/28.0 which require analysis and proper siting of construction to reduce these impacts on this property and surrounding properties to a less than significant level. V. Land Use and Planning The Project site is located within the Eastern Dublin Specific Plan area. The Project site is also located in the Tassajara Gateway subarea which is identified in the Specific Plan. In 1999 a Stage 1 Development Plan was approved for Area H (in which the Project site is located). Although the total square footage of general commercial that is proposed on the site is greater than what was anticipated in the Stage 1 Development Plan, the floor area ratio (.25) will not change. The increase in square footage is a result of an error in the calculation ofthe gross acreage of the site and due to the re-alignment of Dublin Boulevard and Grafton Street. The proposed square footage ofthe site however falls within the square footage anticipated in the Tassajara Gateway subarea and reviewed in the Eastern Dublin EIR which anticipated a greater amount of commercial acreage in the area than what was estimated in the 1999 Mitigated Negative Declaration. Project Impacts a) Would the proposed Project physically divide an established community? NI. The project site is vacant and is located between Dublin Boulevard and Northside Drive. Commercial development has been anticipated on the site since the adoption of the Eastern Dublin Specific Plan and in the Stage I Planned Development Rezone. CEQA Addendum for Grafton Station Area H City of Dublin 27 June 2006 Additionally, residential development is currently underway near the site and commercial development is anticipated adjacent to the site in the future. b) Would the Project conflict with any applicable land use plan, policy or regulation? NI. The proposed Project site has a land use designation ofGC (General Commercial) and GC/CO (General Commercial/Campus Office). The land use designations permit a combination of general commercial and campus office uses on the site (with campus office limited to 10.5 acres). The proposed Project includes the development of a shopping center with general commercial uses. The proposed Project is compatible with the type of development anticipated in the Eastern Dublin Specific Plan, General Plan and the Stage 1 Development Plan. As discussed previously, the proposed Project would result in a shopping center which is 25,059 square feet larger than the development approved under the Stage 1 Planned Development. Although the shopping center square footage will increase over the approved square footage for Area H, the additional square footage was studied in the Eastern Dublin EIR and the proposed square footage falls within the limits previously studied in the EIR. c) Would the Project conflict with a habitat or natural community conservation plan? NI. A Habitat or natural community conservation plan has not been adopted within the Eastern Dublin Specific Plan area and therefore development on the project site would not impact an established plan. Overall, no additional impacts to land use and planning (as identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration) are expected to occur as a result ofthis Project. VI. Mineral Resources The Project site contains no known mineral resources. Project Impacts A, b) Would the project result in the loss of availability of significant mineral resources? NI. Both the Eastern Dublin EIR and the 1999 Mitigated Negative Declaration did not identify any significant mineral resources on this site. Overall, no additional impacts to mineral resources (as identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration) are expected to occur as a result ofthis Project. XI. Noise Major sources of noise on and adjacent to the project site include noise generated by vehicles on 1-580, Tassajara Road and Dublin Boulevard. CEQA Addendum for Grafton Station Area H City of Dublin 28 June 2006 The Eastern Dublin EIR identified Impact 3.1 OlE regarding the exposure of residences to noise from construction equipment. Because residences are located near the subject property, construction ofthe project will be required to adhere to Mitigation Measures 3.10/4.0 and 3.10/5.0. Project Impacts A, d) Would the Project expose persons or generation of noise levels in excess of standards established by the General Plan or other applicable standards? LS. The City of Dublin General Plan includes policies which requires the development to be constructed in accordance with the City's noise exposure limits (see Table 9.1 in the General Plan). The project will be required to conform to these requirements. b) Would the Project expose persons to excessive groundbourne vibration or groundbourne noise levels? NI. No impacts are anticipated for groundbourne vibration or noise, since no sources of vibration currently exist within or adjacent to the Project, such as heavy industrial facilities or railroads. c) Would the Project substantially increase permanent ambient noise levels? LS. The Eastern Dublin EIR identified permanent noise impacts related to vehicular traffic increases as an unavoidable and unmitigatable impact. A Statement of Overriding Considerations was adopted for this impact which has reduced the impact to a less than significant level. Ej) For a Project located within an airport land use plan or within two miles of an airport, would the project expose people to excessive noise levels? NI. The Eastern Dublin EIR notes that noise related to aircraft flyovers from the Livermore Municipal Airport are insignificant for the Eastern Dublin planning area. Overall, no additional impacts related to noise (as identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration) are expected to occur as a result of this Project. XII. Population and Housing The Eastern Dublin Specific Plan anticipates that 13,648 dwelling units will be constructed in the Eastern Dublin Planning Area at buildout (with an estimated population of3I,639 units). The California Department of Finance has determined that the total City of Dublin's population was 39,931 as ofJanuary 1, 2005. Proiect Impacts a) Would the Project induce substantial population growth in an area, either directly or indirectly? LS. Approval ofthe proposed Project is consistent with the Eastern Dublin Specific Plan, Eastern Dublin EIR and the land use identified in the Stage I Development Plan. The proposed amendment to the Stage 1 Development Plan CEQA Addendum for Grafton Station Area H City of Dublin 29 June 2006 would increase the approved square footage by 25,059 square feet; however, the total square footage is consistent with the floor area ratio and the total development potential (square footage) identified in the Tassajara Gateway subarea (Section 4.9.1 of the Eastern Dublin Specific Plan). Additionally, the proposed Project is a commercial development and therefore will not significantly increase the population in the area. b, c) Would the Project displace a substantial number of existing housing units or people? NI. The existing site is vacant. Overall, no additional impacts with respect to population and housing (as identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration) are expected to occur as a result ofthis Project. XIII. Public Services. Fire Protection: The City of Dublin contracts with the Alameda County Fire Department for fire protection services including fire suppression, fire prevention, education, inspection services and hazardous material control to the community. Police Protection: The City of Dublin contracts with the Alameda County Sheriff Department to provide 24-hour security patrols throughout the community in addition to crime prevention, crime suppression and traffic safety. Schools. The Dublin Unified School District (DUSD) provides educational services to residents in the City of Dublin. Maintenance. Maintenance of public streets, roads and other governmental facilities are the responsibility of the City of Dublin Public Works Department. Solid Waste Services. Solid waste services are provided by Amador Valley Industries. Proi ect Impacts a) Fire protection? LS. Construction of the proposed project would increase demand for fire and emergency services on the site. The Project will be required to reduce these impacts by installing fire sprinklers and new fire hydrants and by meeting the minimum fire flow requirements in the Uniform Building Code and the Uniform Fire Code. b) Police protection? LS. An increase in the demand for police services may occur as a result of the construction of the commercial shopping center largely due to an increase in theft on the site. The Project will be required to comply with Mitigation Measure 3.7/5.0 which requires additional police personnel (provided by the City) and the project to be reviewed by the Police Department. CEQA Addendum for Grafton Station Area H City of Dublin 30 June 2006 c) Schools? NI. The proposed Project is for the construction of a 318,000 sq. ft. commercial shopping center. The proposed shopping center will not significantly increase demand for schools in the area. d) Maintenance of public facilities, including roads? LS. Approval of the proj ect would increase the long-term maintenance demand for roads. However, the additional demands will be offset by additional City impact fees and property tax revenues. e) Solid waste generation? LS. Approval of the Project would increase generation of solid waste during construction and during the life of the shopping center. The Project will be required to provide adequate garbage and recycling facilities on the site. Additionally, the Eastern Dublin EIR requires adherence to Mitigation Measures 3.4/37.0 - 40.0 which requires the preparation of a solid waste management plan. Overall, no additional impacts with respect to public services (as identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration) are expected to occur as a result of this Project. XIV. Recreation Nearby community and regional parks include: Emerald Park, a 50-acre City park and Bray Commons, a neighborhood park. Project Impacts a) Would the project increase the use of existing and neighborhood or regional parking? NI. The proposed Stage 1 Planned Development Rezoning and Project will not result in an increase in the number of residential units constructed in the area. As a result, there will be no impacts on neighborhood or regional park facilities. b) Does the Project include recreational facilities or require the construction or expansion of facilities which may have an adverse impact on the environment? NI. The proposed Project does not include any recreational facilities. Overall, no additional impacts to recreation (as identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration) are expected to occur as a result ofthis Project. XV. Transportation/Traffic The 1999 Mitigated Negative Declaration included Mitigation Measure 8 and 9 which required transportation improvements to be installed throughout the City. Please refer to the 1999 Mitigated Negative Declaration for more information regarding this section. CEQA Addendum for Grafton Station Area H City of Dublin 31 June 2006 Existing Transportation Network The project site is served by a number of regional freeways and sub-regional arterial and collector roadways including: Interstate 580 - An eight lane east-west freeway that connects Dublin with local cities such as Livermore to the east and Hayward and Oakland to the west. Interchanges near the project site include Dougherty/Hopyard Road, Hacienda Drive, Tassajara Road!Santa Rita Road and Fallon Road!EI Charro Road. Dougherty Road - A six lane road between Dublin Boulevard and 1-580 (the road continues as a six lane road as Hopyard Road in Pleasanton). This road reduces to four lanes from Dublin Boulevard to the the Alameda County/Contra Costa border where it reduces to two lanes. Dublin Boulevard - This is a major arterial roadway in the City. The road is typically four lane road except for - check this out. This road will connect with Fallon Road in the future. Hacienda Drive - An arterial roadway designed to provide access to 1-580. This road contains six lanes south ofI-580 and four lanes north of Dublin Boulevard. Arnold Drive - This is a north-south two lane road which connects Gleason Drive to Dublin Boulevard. The road will extend south of Dublin Boulevard in the future to connect with the Dublin Transit Center. Gleason Drive - This is an east-west two-lane road parallel to and north of Dublin Boulevard. Gleason Drive runs from Arnold Drive to Fallon Road. Portions of Gleason Drive are four lanes and a portion of this road is two lanes. Tassajara Road - This road extends from Santa Rita Road at 1-580 to the Town ofDanville (where it becomes Camino Tassajara). The road is a four lane road which turns into a two lane road in the more rural areas ofthe City. Santa Rita Road - A six lane divided urban arterial roadway from the 1-580 interchange south to Valley Avenue in Pleasanton. This road primarily serves the east side of Pleasant on, including the Hacienda Business Park and provides access to downtown Pleasanton. Fallon Road - A two lane road which extends from 1-580 and connects with Gleason Drive. In the future, Dublin Boulevard will be extended and will connect with Fallon Road. Existing Intersection Operations The Traffic Study completed in conjunction with the 1999 Mitigated Negative Declaration found that the intersections near the project site operated at an acceptable level of service (which is defined by the City of Dublin as an LOS ofD or better). CEQA Addendum for Grafton Station Area H City of Dublin 32 June 2006 Future Baseline Conditions To implement the transportation and circulation aspects of the Eastern Dublin Specific Plan, the City of Dublin has undertaken a comprehensive program of transportation improvements in the community. The program includes upgrades to 1-580 freeway intersections, construction of new roads and improvements to existing roads. These improvements are primarily funded by fees levied on new development in Eastern Dublin or are required to be constructed by developers in conjunction with their projects. Future Baseline Intersection Operations A Traffic Study was completed in conjunction with the 1999 Mitigated Negative Declaration analyzed the future baseline intersection operations with existing traffic, traffic from approved projects and traffic from other pending development in the area. With the future development in Eastern Dublin and appropriate traffic improvements in the City, the traffic study found that the operation of all study intersections could be maintained at an LOS of D or better. Project Impacts a) Would the Project cause an increase in traffic, which is substantial to existing traffic load and street capacity? LS. The 1999 Mitigated Negative Declaration concluded that the proposed project in addition to the approved projects and future projects in the area would potentially create significant impacts, however these impacts could be mitigated to a less than significant level. The 1999 Mitigated Negative Declaration included Mitigation Measure 8 which required that several transportation improvements be installed throughout the City and Mitigation Measure 9 which required Tassajara Road to be widened from six to eight lanes between 1-580 and Dublin Boulevard. b) Would the Project exceed, either individually or cumulatively, a LOS standard established by the County CMA for designated road? NI. As shown in the 1999 Mitigated Negative Declaration, all nearby intersections can be mitigated to a Level of Service D or better, which exceeds the minimum Level of Service E established by the Alameda County Congestion Management Agency. c) Would the Project result in a change in air traffic patters? NI. The proposed project would have no impact on air traffic patterns because it is a regional serving commercial development. d) Would the project substantially increase hazards due to a design feature or incompatible use? LS. Approval ofthe Project would result in the construction of new driveways, circulation routes, access points and the extension of Grafton Street. All new streets and other circulation improvements on the site will be constructed in accordance with City design requirements to minimize substandard turning radii, provide for maximum sight visibility distances and minimize other potential hazards. CEQA Addendum for Grafton Station Area H City of Dublin 33 June 2006 e) Would the Project result in inadequate emergency access? NI. The proposed Project has been reviewed with respect to emergency access by the City's Fire Department and the Police Department. The Departments have concluded that the site has been adequately designed for emergency access. f) Would the Project result in inadequate parking capacity? NI. The proposed project has been reviewed with respect to parking and the City has determined that the proposed Project meets the requirements of the Dublin Zoning Ordinance with respect to parking, g) Would the Project create hazards or barriers for pedestrians or bicyclist? NI. The Project has been designed to minimize potential hazards to pedestrians and bicyclists. XVI. Utilities and Service Systems The project site is served by the following service providers: Sewage treatment and local water supply: Dublin San Ramon Services District and Alameda County Flood Control and Water Conservation District, Zone 7. Regional water supply and distribution: Alameda County Flood Control and Water Conservation District, Zone 7 Storm drainage: City of Dublin/Alameda County Floor Control and Water Conservation District, Zone 7. Proiect Impacts a) Would the Project exceed wastewater treatment requirements of the RWQCB? NI. The regional wastewater treatment plant is currently operating in compliance with local, state and federal water quality standards. Mitigation measures 3.5/1.0 through 3.5/22.0 in the Eastern Dublin EIR addresses wastewater collection, plant capacity, treatment and storage. This mitigation measures will continue to apply to this project. b ) Would the Project require new water or wastewater treatment facilities or expansion of existingfacilities? LS. Existing water and sewer lines will need to be extended to serve the Project site. The extension has been planned as part of the Eastern Dublin Specific Plan and the proposed Project will not impact this extension. c) Would the proposed Project require new storm drainage facilities? LS. A new drainage system will be constructed as part of the construction ofthis project. The Project will be required to comply with Mitigation Measure 5 (identified in the 1999 Mitigated Negative Declaration) which requires the developer to prepare a CEQA Addendum for Grafton Station Area H City of Dublin 34 June 2006 Stormwater Pollution Prevention Plan to ensure that the proposed drainage system will accommodate stormwater runoff from the Project. d) Are sufficient water supplies available to support the Project? LS. The proposed Project will increase the demand for water for domestic and irrigation purposes. The increase in water could be accommodated by Zone 7 and the Dublin San Ramon Services District. e) Does the current wastewater provider have adequate capacity to serve the project? LS. Approval ofthe Project and construction of the new shopping center will increase the demand for wastewater treatment over present conditions. Based on information contained in the Eastern Dublin EIR, the Dublin San Ramon Services District has indicated that the local wastewater treatment plant has adequate capacity to serve the proposed project. f) Would the project be served by a landfill with adequate capacity to serve the Project? LS. Construction of the Project would increase solid waste generation over time. However, as statewide regulations mandating increased recycling take effect, the amount of solid waste reaching the landfill would decrease. Solid waste generation resulting from the proposed shopping center has been studied in the Eastern Dublin EIR which indicated that the hauler can accommodate this project. g) Would the Project comply with federal, state and local statues and regulations related to solid waster? NI. The City of Dublin and the City's solid waste provider would ensure that developer ofthe Project would adhere to federal, state and local solid waste regulations. Overall, no additional impacts to utilities and service systems (as identified in the Eastern Dublin EIR or the 1999 Mitigated Negative Declaration) are expected to occur as a result of this Project. XV. Mandatory Findings of Significance a) Does the project have the potential to degrade the quality of the environment, substantially reduce the habitat offish or wildlife species, cause afish 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 of endangered plant or animal or eliminate important examples of the major periods of California history or prehistory? No. The analysis in this Initial Study indicates that the proposed Project will not have a significant adverse impact on the overall environmental quality, including biological resources or cultural resources with the implementation of mitigation measures recommended in the 1999 Mitigated Negative Declaration and the mitigation measures, including Statement of Overriding Consideration contained in the _ Eastern Dublin EIR.. CEQA Addendum for Grafton Station Area H City of Dublin 35 June 2006 b) Does the Project have impacts that are individually limited, but cumulatively considerable? No. The Project site lies within the Eastern Dublin Specific Plan, specifically Tassajara Gateway subarea, and the proposed development is consistent with the commercial development planned for the area and the Tassajara Gateway subarea in which the project area is located. c) Does the Project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? No. No such impacts were discovered in the course of preparing this Initial Study or the 1999 Mitigated Negative Declaration, or Easter Dublin EIR.
