areas outside of environmentally sensitive areas, and buffers for these areas shall be doubled until such time as a development is proposed on the site. Clearing is not permitted in any area designated as buffer and/or wildlife corridors,and must not occur within 300 feet of a residential area. Clearing should not remove coniferous trees. Erosion control measures must be installed to prevent sediment and erosion impacts to adjacent properties and environmentally sensitive areas and their buffers. A clearing plan must be submitted to the City Planning and Engineering and Public Services Departments for their approval,and temporary detention ponds must be provided for any clearing as required by the Public Works Department. 4.3.3 Mitigating Impacts on Streams,Fish,and Fish Habitat 1. Areas with soils suitable for large scale infiltration should be protected. Due to the construction of new impervious surfaces,stormwater volumes will increase significantly. Base flow reductions can only be mitigated by the use of infiltration systems for collected stormwater. Infiltration systems will be required whenever feasible,as determined by the Public Works Department,particularly for rooftop runoff. This study area, however,has few areas of soils suitable for large scale infiltration. The Associated Sand and Gravel property located south of Sievers-Duecy Blvd.is one area where stormwater is currently being infiltrated. Infiltration must continue to occur on that site. 4.3.5 Mitigating Impacts of Development on Water Quality and Groundwater 1. Developments with hazardous materials on-site, including fuel tanks, must comply with all applicable local,state and federal requirements.All developments using toxic or hazardous materials must incorporate facilities and procedures for the safe handling and effective monitoring of toxic or hazardous materials,which include spill entrapment,training,and special handling,thus reducing the potential for release of hazardous or toxic materials to the groundwater system. (See Section 3.6 of the EIS). 2. • Staging areas for vehicle maintenance activities during construction must be specified. These areas must be well away from all drainage courses. • 3. Application of fungicides,herbicides,insecticides,and fertilizers is prohibited on all sites from January through April when soils are frequently saturated and storm events generate substantial runoff. 4. All storm drains must be stenciled with language similar to the following: "Dump No Waste,Drains to (Stream/Wetland/Groundwater)." This reminder is typically spray-painted on to the ground adjacent to the catch basin with the use of a stencil. The treatment needs to be repeated,approximately annually,when the paint wears off. The developer/owner may either perform the stenciling,or give permission for volunteer groups to enter onto the property and perform the stenciling. 5. During construction activities,all spills must be contained and removed in such manner as to prevent their entering the waters and soils of the state. Cleanup of spills shall take precedence over other work on-site. Section 5: AIR QUALITY AND ODOR All permitted future uses must obtain a Notice of Construction(NOC)as applicable and use best available control technology. As necessary,air quality studies may be required by PSAPCA in order to obtain permits. Section 6: ENERGY AND NATURAL RESOURCES 6.1 ELECTRIC ENERGY 6.1.3 Mitigation Measures ff
