(@ ATTACHMMe 21~ MEMORANDUM ... BUILDING INFRASTRUCTURE & TRANSPORTATION To: Blake Lyon- Senior Planner Date: June 29, 2010 ~ ~% ~~ From: Paul Wiflis, P:E - Senior Civil Engineer Subject: One Marina (Peninsula Park) Tentative Map Review The foHowing comments were generated by City staff and our consultant based on the initial submittal of two Vesting Tentative Maps for the One Marina Project. General: The City will require a peer review to done ~y its own geotechnical consultant (Impact 11-1 from the EIR). The soils report does not seem to adequately address the issues of dewatering, and liquefaction pursuant to Division of Mines and Geology Publication SP 117, (Impact 11-2, 11-3, 11-4). The grading recommendations need to be expanded in more detail. We would recommend the use of the City's Standard Technical Specifications (Spec Section 02220, Grading and Earthwork), with special inspection provided by an approved geotechnical engineer. The reports do show highly corrosive soils, meaning that the City's Standard Technical Specifications for Cathodic Protection (Spec. Section 02661) apply; concrete shall confOInJ to Spec Section 02550 for corrosion resistant concrete. The Geotechnical Engineer's recommendation for sand backfill and bedding at this location is not acceptable, Rather, the City's Technical Specification for Trenching and Backfill (Spec. Section 02202) should be followed. Vesting Tentative Maps: It is the intent of the developer to submit multiple fmal maps based on the approval of a single tentative map. This procedure is acceptable. The One Marina Vesting Tentative Map proposes to subdivide the area into 4 Lots, and the second Vesting Tentative Map proposes to subdivide lot 2 for the purpose of 56 condominium units, The approval oftheresubdivision oflot 2 is dependent on the successful approval of the 4 lot subdivision and should be processed as two separate map approvals. Although this can be presented in one meeting, should there be any concern or recommendations to change the 4 lot subdivision, the approval and discussion of the second Vesting Tentative Map should be withheld until the 410t subdivision is formally approved. The radii at the curb returns at the street entrances and at all turns shall accommodate the 'WB-50 truck turning template (Impact 7-13), Confirm that the proposed project has adequate parking, per the Table 7.17 in the Appendix 5 of the EIR (Impact 7-14), Prepare a Notice of Intent (and submit a copy to the City) for the proposed grading operation. \ Minor corrections have been redlined on the submitted check prints and should be corrected and resubmitted by the applicant priorto the Planning Commission meeting. .
