PC-2009-42, PUD-80, CITY OF PLEASANTON

Resolution No. PC -2009-42 Page Four The site is not located within an Alquist-Priolo Earthquake Fault Zone The proposed project will require the construction of stormwater detention facilities, to contain the 100 -year flood. An EIR mitigation measure for the project requires the site to be removed from the flood hazard area prior to occupancy. However, this is a City park, and the Engineering Division will require this to be completed prior to the issuance of a building permit. Engineering modeling indicates that implementation of the Livermore flood protection improvements, as part of Livermore's approved EI Charro Specific Plan, will provide sufficient detention to prevent inundation of the Staples Ranch site for the 100 -year storm event. It is anticipated that Livermore will begin the construction of these improvements next year. To help prevent the erosion and pollution of the Arroyo Mocho, on-site stormwater will be treated on-site for contaminates and directed into the basin before being released into the Arroyo Mocho. On-site erosion control and dust suppression measures will be documented in the improvement plans and inspected by the Building and Safety Division during construction. The grading, as conditioned, takes into account environmental characteristics and is designed in keeping with the best engineering practices to avoid erosion, slides, or flooding to have as minimal an effect upon the environment as possible. Therefore, this finding can be made. 5. Streets and buildings have been designed and located to complement the natural terrain and landscape. As stated above, a minus grading for the basin, minimal changes to the natural grade elevations are proposed. There are no trees on-site. Over 100 new trees are proposed to be planted as part of the project. Shrubs and ground cover, including native California species, will be planted. As conditioned, the project will adhere to Alameda County Waste Management Authority's Bay -Friendly Landscape Guidelines, and landscaping species from the proposed forage and shelter plan list will be incorporated into the final plans. The project, as conditioned, has been designed and located to complement the natural terrain and landscape. Therefore, this finding can be made.
