SECTION 4 Alternatives Compared As noted in Section 1, after proposing and describing practicable Alternatives, the Harbor Basin Study now attempts to compare them with each other. The Study does not, however, attempt to rate or rank the alternatives in such a manner as to make a suggestion or a recommendation for a preferred one. Rather, this section contrasts them under what might eventually comprise a list of selection criteria for the City: Recreation, Consistency with Cal -Coast's Proposed Landside Development, Sedimentation Patterns and Hydrodynamics, Technical and Regulatory Opportunities and Constraints, and Relative Initial and Long-term Maintenance Costs. 4.1 Recreation This section describes the types of recreational uses that would be provided under each of the three alternatives being considered, makes a determination of whether those types of recreational uses would be considered "aquatic" in nature, and makes some assumptions regarding existing demand for those types of uses. Overall, a variety of recreational uses would be provided under each of the alternatives being considered. The types of recreational uses, however, would differ from one another in terms of costs to the public and whether they would be attractive to a large percentage of the population or only to a select group. It is important to note that a range of recreational opportunities in addition to those proposed within the Harbor Basin are provided in the Marina's shoreline areas, including golf courses, a par course, Marina Park, and those being proposed by Cal -Coast. These existing or future amenities are not considered here. Section 4.2, below, considers recreational and other uses that are being proposed for the shoreline areas by Cal -Coast. Marina Park Alternative As described in Section 2, the Marina Park Alternative would include a smaller Marina than exists today, consisting of approximately 185 slips, a multi -use perimeter promenade along the interior edge of the Harbor Basin, and a small, publicly accessible beach area with stepped shoreline seating and a stage area. The western portion of the harbor basin would be dominated by natural features, including a marsh, wildlife refugia, and various landscape features. In combination, these components would provide a variety of opportunities for passive and active recreational activities, including boating, water contact, walking, bird watching, and attending of performances and other events at the beach. Some proposed uses, such as boating, would be fairly San Leandro Marina Harbor Basin 4-1 ESA / 210461 Alternatives Study March 2011
