geotechnical engineer shall review and approve all foundation, retaining walls, drainage and geotechnical aspects of the final grading and improvement plans and shall certify on the plans or as otherwise acceptable to the Director of Engineering/City Engineer that the plans are in general compliance with the recommendations of the project geotechnical report. The applicant shall bear all costs for work related to this condition by their geotechnical engineer. (Address this condition prior to permit issuance) 48. HYDROLOGIC AND HYDRAULIC CALCULATIONS: The applicant's California licensed civil engineer shall submit a detailed hydrologic and hydraulic study for the design storm event as provided for in the City's Design Guide dated 1984 with the first submittal of the improvement plans to the Engineering Department subject to the review and approval of the Director of Engineering/City Engineer. (Address this condition prior to permit issuance) 49. DUST CONTROL PLAN: The applicant shall submit a written dust control plan or procedure with the first submittal of the grading and improvement plans to the Engineering Department subject to the review and approval of the Director of Engineering/City Engineer. (Address this condition prior to permit issuance) 50. EROSION CONTROL MEASURES FOR COMMERCIAL DEVELOPMENTS: The applicant shall submit an erosion control plan designed by a certified Qualified SWPPP (Stormwater Pollution Prevention Plan) Practitioner(QSP) for all projects disturbing 1 acre or more or by a California licensed civil engineer or California licensed landscape architect for all projects disturbing less than 1 acre of land, subject to the review and approval of the Chief Building and Safety Official. All cut and fill slopes shall be hydromulched/hydroseeded and stabilized immediately after the completion of grading work and in no case later than October 1, unless otherwise approved by the Chief Building and Safety Official. No grading shall occur between October 1 and April 30 unless erosion control measures are in place, subject to the review and approval of the Chief Building and Safety Official. Such measures shall be maintained until the permanent landscaping is completed to the satisfaction of the Chief Building and Safety Official and the Notice of Termination for the coverage under the Construction General Permit, if applicable, is approved by the State Water Resources Board. (Address this condition prior to permit issuance) 51. TRASH COLLECTION: The site appears to lack an enclosure for collection of trash. The applicant shall amend the plans to show a trash enclosure, with appropriate construction details, located in an area where the collection vehicle will have convenient access. If provided, the enclosure must have a roof. (Address this condition prior to permit issuance). Project Specific Condition. 52. EXISTING FIRE HYDRANT: Referring to Sheet C5, an existing fire hydrant located immediately west of the Stanley Boulevard driveway will apparently be disconnected from a 6"water service and connected to a new 8"water service. The applicant shall include a shut off valve for this hydrant at the "T"fitting between the hydrant lateral and the new 8" main. This valve will preserve fire flows to the buildings if the hydrant is inadvertently knocked over by a wayward vehicle. (Address this condition prior to permit issuance). Project Specific Condition. 53. EMERGENCY OVERLAND RELEASE: The proposed grading and finish floor elevations in relationship to elevation of the Stanley Boulevard and Nevada Street indicate that this is a sump condition. In accordance with the City's Design Guidelines, the property shall be protected from storm water inundation for a 50-year recurrence interval weather event. The applicant proposes to utilize the 24-inch storm water pipe that was installed with the Nevada Street construction to serve this property. The applicant has one of two options to comply with the City's Design Guidelines: a. EITHER: Verify through hydraulic calculation that the 24-inch storm drain pipe is adequate in size and slope to convey flows from a 50-year recurrence interval weather event to Arroyo Del Valle creek without inundating the proposed new buildings.
