Geology and Soils S-I The City would implement the recommendations of the geotechnical report to mitigate impacts from strong seismic groundshaking and seismic-related ground failure. Hydrology and Water Quality DPW WQ-1. The following stormwater pollution-prevention measures shall be implemented to reduce water quality impacts on Arroyo del Valle: Erosion and Sediment Control Practices: Erosion and sediment control practices that may be used for the project include minimizing the amount of area exposed at a given time, scheduling grading and bridge work during the drier months (April to September), preservation of existing vegetation to the extent practicable, temporary and permanent seeding and mulching, dust control, fiber rolls, stabilized construction entrances, tire washes, silt fencing, storm drain inlet protection, temporary swales and sediment traps. Post-Construction Storm Water Management Measures: Post-construction stormwater management measures for the project may include deep-sump catch basins, vegetated swales and infiltration and/or detention basins. Detention basins (if used) would be designed to allow for natural habitat, where feasible (City of Pleasanton Program 6.2). - Non-Storm Water Management Measures: Non- storm water management measures for the project may include storage of hazardous materials, chemicals, fuels, and oils and fueling of construction equipment at least 150 feet away from Arroyo del Valle, storing materials onsite in a neat, orderly manner in appropriate containers and, if possible, under a roof or other enclosure and disposing waste in accordance with the manufacturer's or the local and state recommended methods for proper disposal. & - SpilIPrevention and ControIMeasures: Spill DPW During construction period Prior to Section 401 certification as part of the NPDES process DPW RWQCB Page 9 of 13
