1. Introduction <br />Although this study does not analyze any specific redevelopment options for the upland areas, it <br />addresses the interface between the proposed Harbor Basin alternatives and the types of uses <br />envisioned in the immediate vicinity. Moderate changes to the development concept would not <br />impact the conclusions of this study. See Section 4.2 for this discussion. <br />1.3 Scope and Methodology <br />The central mission of the City of San Leandro Harbor Basin Alternatives Study can be stated in <br />a straightforward way: first, to provide alternative configurations for the Harbor Basin which will <br />retain aquatic recreational opportunities and mesh well with existing and potential landside uses <br />but which will be in equilibrium, or near equilibrium, in terms of natural sedimentation processes; <br />second, to consider options for the DMMS as an expanded and improved natural habitat which <br />also can be a City amenity. <br />This report is based on three study sessions held on October 21 and November 17, 2010 and <br />January 13, 2011 between the technical team, the City of San Leandro staff, and Cal -Coast, as <br />well as review of pertinent background documentation and professional opinion. The report seeks <br />to address the following topics and answer the following questions for each of the alternatives: <br />• Recreation. Does it provide aquatic recreation? What types? Can we determine the <br />demand for the types of recreation offered? <br />• Consistency with Cal -Coast Development Plans. Is it complementary with Cal -Coast <br />Development planning? <br />• Sedimentation Patterns, Hydrodynamics. Is it sustainable with natural hydrology and <br />sediment transport processes? How close is the alternative to being self sustaining with respect <br />to sedimentation? <br />• Technical and Regulatory Opportunities and Constraints. Which permits will be necessary? <br />How difficult will it be to secure permits? How are the different agencies likely to view the <br />different alternatives? <br />• Relative Initial and Long-term Maintenance Costs. All cost and revenue projections are <br />not to be construed as a detailed fiscal analysis. On a relative basis, and solely for conceptual <br />level planning purposes, what is the relative cost of each alternative considering: <br />— Environmental review and permitting; <br />— Design and implementation ; <br />— Long-term maintenance (using existing City staffing categories and costs, and <br />assuming a comparable level of service); and <br />— Potential revenues, as appropriate. <br />In addition, Section 5 of this report provides alternatives for future use of the City's Dredged <br />Material Management Site (DMMS). Proposed DMMS alternatives considered in this section are <br />(1) operating the site as a DMMS for other harbors, (2) shorebird habitat enhancement, (3) tidal <br />marsh restoration, and (4) seasonal wetland restoration. These options are considered relative to <br />each of the alternative uses of the Harbor Basin. <br />San Leandro Marina Harbor Basin 1-4 ESA / 210461 <br />Alternatives Study March 2011 <br />
