• 2. In addition to American Society of Heating Refrigeration and Air-Conditioning Engineers <br /> (ASHRAE) standards for acceptable ventilation of subsurface parking and building <br /> mechanical rooms, a vapor barrier membrane material that is resistant to volatile organic <br /> compounds (VOCs) in addition to water vapor (such as SikaProof A08) shall be installed <br /> to provide complimentary protection for the redevelopment. <br /> D. Municipal Regional Stormwater Permit Provision C.3 (Clean Water Program) <br /> 1. Referring to the C.3 Compliance Exhibit, the following deficiencies were noted on the <br /> Preliminary Stormwater Management Plan. Said deficiencies shall be corrected during the <br /> building permit phase and prior to issuance of Building Permit: <br /> a. The table in the upper right corner of the C.3 compliance exhibit contains no <br /> backup to support the Filterra Unit treatment size conclusions. The applicant shall <br /> submit a cut sheet stating the treatment sizes. <br /> b. Volume flow calculation for District Meter Area (DMA) 4 shows that depth of <br /> stored runoff in surface ponding area is 42.06 inches whereas for DMA 5 it is - <br /> 16.58 inches, DMA 8 it is -19.16 inches and DMA 9 it is -19.09 inches. It cannot <br /> be verified as to what the ultimate ponding depth for the bio-treatment area (IMP- <br /> 4) is. As per Alameda County C.3 Technical Guidance Manual, ponding depth <br /> cannot be more than 12 inches. Similarly,the ponding depth cannot be verified for <br /> other treatment measures. <br /> c. Plans shall show a pipe network that conveys treated storm water to the offsite <br /> public system. <br /> d. The C.3 improvements must be in compliance with the Alameda Countywide <br /> Clean Water Program Guidance (latest edition), and the most current Municipal <br /> Regional Permit. The Waste Dischargers Identification (WDID) number, once <br /> obtained from the Regional Water Quality Control Board, shall be printed on the <br /> grading plans. <br /> E. Lot Line Adjustment <br /> 1. The proposed project encompasses a total of two adjacent parcels owned by the same <br /> titleholder. Prior to building permit application, the applicant shall merge these two <br /> parcels. The applicant shall complete the form at <br /> http://www.sanleandro.org/civicax/filebank/blobdload.aspx?blobid=3617 and provide <br /> specified documents, lot merger map, plats and legal description and pay the required fee <br /> for processing the application to the Engineering and Transportation Department. Once <br /> the lot merger is approved and recorded, the applicant can proceed with the Building <br /> Permit application. <br /> F. Site Planning <br /> 1. City operates a sanitary sewer network on Washington Avenue across the property <br /> frontage. There is no sanitary sewer network on Thornton Avenue across the subject <br /> property frontage. The proposed site development can therefore tie into the City's network <br /> on Washington Avenue on the Building Permit plans. The City is inspecting any defects <br /> in this sanitary sewer segment on Washington Avenue and if the Pipeline Assessment <br /> Agreement to Conditions February 2,2017 <br /> PLN16-0050 Page 7 of 15 <br />
