proposed. The study shall be based on precise grading and architectural plans including specific construction method details and materials to calculate the necessary exterior to interior noise reduction of approximately 20 dBA to achieve 45 dBA CNEL for residential construction. The precise exterior to interior reduction would be determined in the acoustical study when precise grading plans with building elevations, footprints and architectural plans are available. The acoustic study shall: a. Identify noise insulation features and techniques to reduce interior noise levels to achieve the interior noise standard pursuant to Mitigation Measure NOISE-1A, using features such as upgraded exterior wall and roof assemblies, and upgraded windows and exterior doors. b. Pursuant to Mitigation Measure NOISE-113, all residential units of the Project shall include an alternative form of ventilation, such as noise -baffled passive air ventilation systems or mechanical air conditioning systems, that would allow windows to remain closed for prolonged periods of time to meet the interior noise standard of 45 dBA Ldn established by the City and the Uniform Building Code Requirements. c. Demonstrate compliance with Mitigation Measure Noise-4 addressing construction noise. d. All construction contracts shall identify these requirements and shall be acknowledged by the contractor. 50. All plans submitted for building permits shall incorporate all design and construction criteria specified in the updated Geotechnical report(s). The geotechnical engineer shall sign the improvement plans and approve them as conforming to their recommendations prior to issuance of building permits. The geotechnical engineer shall also assume responsibility for inspection of the work and shall certify to the City, prior to acceptance of the work that the work performed is adequate and complies with its recommendations. The geotechnical engineer of record shall prepare letters and as -built documents to document their observances during construction and to document that the work performed is in accordance with the project plans and specifications. As required by the City of San Leandro, all construction activities shall meet the Building Code regulations for seismic safety (i.e. reinforcing perimeter and/or load bearing walls, bracing parapets, etc.). 51. Prior to the issuance of building permits, a Letter of Map Revision (LOMR) and elevation certificate shall be submitted to the City's Chief Building Official in compliance with Municipal Code Chapter 7-9, Floodplain Management and Mitigation Measure HYDRO-7. 52. Prior to issuance of building permits, the Applicant/Developer shall provide documentation that they have submitted proper notice to the Federal Aviation Administration, as required, and received necessary permits and approvals to the satisfaction of the Community Development Director. Prior to Certificate of Occupancy 53. Prior to issuance of any Certificate of Occupancy on the property, improvements required by the project Disposition and Development Agreement prior to Certificate of Occupancy shall be completely installed to the satisfaction of the Community Development Director and the Director of Engineering and Transportation or as outlined in the Disposition and Development Agreement and Development Agreement.
