1. Prior to the final design of the relocated Vineyard A venue, the stability of the slopes of the south bank of the Arroyo del Valle within 200 feet of the proposed location of the roadway shall be evaluated by a qualified Geotechnical Engineer to determine if slope failures could affect the short- and long-term integrity of the constructed roadway or if construction or operation of the roadway could affect the stability of the banks. A geotechnical report shall be prepared for the City that specifies appropriate slope design and construction. Recommendations of the report shall be implemented in the roadway specifications. 4. Drainage Reguirements Relating to Construction a . Grading and drainage design plans shall be submitted to the City Engineer for each phase of development within the Plan Area, and reviewed for compliance with all applicable City requirements . The drainage plans shall demonstrate that the proposed development would minimize or eliminate increases in the volume or rate of runoff associated with both small and large storm events (including two-year to 100-year storm events) from the development sites. 5. Water Quality and Protection Reguirements Relating to Construction a. Projects disturbing more than five acres of land during construction shall be required to file a Notice of Intent (NOi) to be covered under the State NPDES General Construction Permit, for discharges of storm water associated with construction activity. The developer shall propose control measures that are consistent with the State General Permit. A Storm Water Pollution Prevention Plan (SWPPP) shall be developed and implemented for each site covered by the general permit. A SWPPP shall include Best Management Practices (BMPs) designed to reduce potential impacts to surface water quality through the construction and life of the project. A SWPPP shall be prepared such that, when properly implemented, will reduce or eliminate impacts to surface water quality from all phases of the project. Required elements of the SWPPP include the following: 1) Construction storm water management controls shall be implemented which include practices to minimize the contact of construction material, equipment, and maintenance supplies (e.g., fuels , lubricants , paints, solvents, adhesives) with storm water. The SWPPP shall specify properly-designed centralized storage areas that keep these materials out of the rain. It shall also include a monitoring program by the construction site supervisor. 52
