Appendix E(Initial Study/Part 1• • Page 8 Attachment to Appendix E—Initial Study(Part 2) l.a. The Preliminary Environmental Site Assessment submitted by the applicant indicates that underlying soils on the project site have a high shrink-swell potential due to the high content of clay. This could potentially impact future building foundations, resulting in shifts and cracks. Mitigation: Prior to issuance of building permits, plans for new building construction shall be submitted for review and approval to the Chief Building Official. Specific measures, such as shaping building pads to provide drainage away from the building site, shall be included to address the shrink-swell characteristics of the underlying soil. Implementation of this mitigation measure would bring the impact to a less than significant level. 1.b-f. The site is relatively flat and is currently developed with a food manufacturing plant (former Safeway Preserves Plant). Development of the proposed project would not result in an increase in over-covering of soil, as all of the site is either paved or built-up with buildings. The underlying soil is suitable for development and no re-engineering of on-site soils is anticipated. No impacts to on-site soils are anticipated 1.g. This project area lies within approximately 1.8 miles of the Hayward Fault zone and is within a seismically active area. In the event of a major earthquake on the Hayward, San Andreas or other nearby fault, structures or persons in the area would be exposed to damage or risk depending on the magnitude and nature of the earthquake. All construction must comply with the San Leandro Municipal Code which requires all new structures to be engineered and designed to resist the forces imposed by an earthquake. This impact is considered less than significant. 2.a-c. The Traffic Impact Study prepared for the proposed project indicates that the proposed project would not result in a significant increase in vehicular trips to and from the project site. Therefore, air quality impacts are anticipated to be less than significant. No objectionable odors would be produced by the automobile dealership project and no alteration of air movement nor a change in the local climate are anticipated.No air quality impacts are anticipated. 3.a-h. Due to the fact that the project site is currently developed and has housed the former Safeway food manufacturing plant for approximately 55 years, redevelopment of the site with an automobile dealership is not anticipated to affect on-site absorption rates or drainage patterns. There are no surface waters to which drainage might be discharged into. Project drainage would go through the existing storm drain system. No groundwater would be affected by development of the project, nor is the project site within an identified flood zone. No impacts to water resources are anticipated. 4.a-c and 5.a-d. Due to the existing developed state of the project site, no significant, rare or endangered plant or animal species currently exist. Therefore, redevelopment of the site with an automobile dealership would not result in a potentially significant impact. No impacts to plant or animal species are anticipated.
