SAN LEANDRO GENERAL PLAN UPDATE FINAL EIR CITY OF SAN LEANDRO COMMENTS AND RESPONSES PLACEWORKS 5-21 TABLE 5-1 COMMENTS AND RESPONSE MATRIX Comment # Date Comment Response rise.” Pages 4.14-56 - 4.14-57 references Alameda County Flood Control and Water Conservation District participation with the Federal Emergency Management Agency “to study the effects of sea level rise on Bay area shorelines, creeks, and levees and determine what changes may be needed to provide 100-year level of flood protection.” The Bay Plan policies on climate change state, in part that “[w]hen planning shoreline areas or designing larger shoreline projects, a risk assessment should be prepared by a qualified engineer and should be based on the estimated 100-year flood elevation that takes into account the best estimates of future sea level rise and current flood protection and planned flood protection that will be funded and constructed when needed to provide protection for the proposed project or shoreline area. A range of sea level rise projections for mid-century and end of century based on the best scientific data available should be used in the risk assessment. Inundation maps used for the risk assessment should be prepared under the direction of a qualified engineer. The risk assessment should identify all types of potential flooding, degrees of uncertainty, consequences of defense failure, and risks to existing habitat from proposed flood protection devices.” An analysis of potential impacts from sea level rise should be used to evaluate impacts to the San Leandro shoreline, including the proposed zoning changes and preliminary components in the San Leandro Shoreline Development Project. also addressed in the proposed San Leandro 2035 General Plan in the Environmental Hazards Element. Policy EH-1.8 of the proposed Plan is to, "Consider the effects of projected sea level rise in the design and planning of all development, recreational improvements, and infrastructure along the San Leandro shoreline." C01-04 Safety of Fills. On page 4.9-13, the DEIR states “Although there are no development projects currently identified under the proposed (General) Plan, future development could still occur along the San Leandro Shoreline under the proposed (General) Plan.” However, details for a General Plan Amendment for the San Leandro Shoreline Development Project, starting on page 3-128 of the proposed General Plan, identifies housing units, an office campus, a banquet and conference facility, and other preliminary components. Proposed development projects which require Bay fill will be subject to Bay Plan Safety of Fills findings which state, in part, that “New projects on fill or near the shoreline should either be set back from the edge of the shore so that the project will not be subject to dynamic wave energy, be built so the bottom floor level of structures will be above a 100-year flood elevation that takes future sea level rise into account for the expected life of the project, be specifically designed to tolerate periodic flooding, or employ other effective means of addressing the impacts of future sea level rise and storm activity,” and that “adequate measures should be provided to prevent damage from sea level rise and storm activity that may occur on fill or near the shoreline over the expected life of a project.” General Plan Update Action LU-9.4.B: Sustainability and Sea Level Rise recognizes the need for review of future projects to “Ensure that future development at the shoreline takes place in an environmentally sensitive manner, taking into consideration the potential effects of rising sea levels.” Further, Section 66605 of the McAteer-Petris Act authorizes the place of fill in the Bay only for water-oriented uses or minor fill for improving shoreline appearance or public access. As described in Response C01-03, the proposed San Leandro 2035 General Plan includes the existing land use designations for the Shoreline project site and a brief description of anticipated future development. When areas subject to BCDC jurisdiction are proposed for future development, the development will be subject to all applicable BCDC regulatory requirements, including standards for bay fill and preparation of sea level rise assessments. The City notes that sea level rise regulation is evolving. The Shoreline EIR mitigation measures require the project to prepare a sea level rise assessment (Mitigation Measure HYDRO-7); the draft San Leandro 2035 General Plan includes Policy EH-1.8 to, "Consider the effects of projected sea level rise in the design and planning of all development, recreational improvements, and infrastructure along the San Leandro shoreline." C01-05 Shoreline Protection. Page 4.8-8 of the DEIR recognizes the policies of the Commission: “Projects in BCDC jurisdiction that involve Bay fill must be consistent with the Bay Plan The proposed project is a General Plan update and does not include any development projects involving Bay fill.
