Planning for this area should consider potential impacts related to sea level rise.” <br />Pages 4.14-56 - 4.14-57 references Alameda County Flood Control and Water Conservation <br />District participation with the Federal Emergency Management Agency “to study the effects of <br />sea level rise on Bay area shorelines, creeks, and levees and determine what changes may be <br />needed to provide 100-year level of flood protection.” <br />The Bay Plan policies on climate change state, in part that “[w]hen planning shoreline <br />areas or designing larger shoreline projects, a risk assessment should be prepared by a qualified <br />engineer and should be based on the estimated 100-year flood elevation that takes into <br />account the best estimates of future sea level rise and current flood protection and planned <br />flood protection that will be funded and constructed when needed to provide protection for <br />the proposed project or shoreline area. A range of sea level rise projections for mid-century and <br />end of century based on the best scientific data available should be used in the risk assessment. <br />Inundation maps used for the risk assessment should be prepared under the direction of a <br />qualified engineer. The risk assessment should identify all types of potential flooding, degrees <br />of uncertainty, consequences of defense failure, and risks to existing habitat from proposed <br />flood protection devices.” An analysis of potential impacts from sea level rise should be used to <br />evaluate impacts to the San Leandro shoreline, including the proposed zoning changes and <br />preliminary components in the San Leandro Shoreline Development Project. <br />Safety of Fills. On page 4.9-13, the DEIR states “Although there are no development projects <br />currently identified under the proposed (General) Plan, future development could still occur <br />along the San Leandro Shoreline under the proposed (General) Plan.” However, details for a <br />General Plan Amendment for the San Leandro Shoreline Development Project, starting on page <br />3-128 of the proposed General Plan, identifies housing units, an office campus, a banquet and <br />conference facility, and other preliminary components. <br />Proposed development projects which require Bay fill will be subject to Bay Plan Safety <br />of Fills findings which state, in part, that “New projects on fill or near the shoreline should <br />either be set back from the edge of the shore so that the project will not be subject to dynamic <br />wave energy, be built so the bottom floor level of structures will be above a 100-year flood <br />elevation that takes future sea level rise into account for the expected life of the project, be <br />specifically designed to tolerate periodic flooding, or employ other effective means of <br />addressing the impacts of future sea level rise and storm activity,” and that “adequate <br />measures should be provided to prevent damage from sea level rise and storm activity that may <br />occur on fill or near the shoreline over the expected life of a project.” General Plan Update <br />Action LU-9.4.B: Sustainability and Sea Level Rise recognizes the need for review of future <br />projects to “Ensure that future development at the shoreline takes place in an environmentally <br />sensitive manner, taking into consideration the potential effects of rising sea levels.” Further, <br />Section 66605 of the McAteer-Petris Act authorizes the place of fill in the Bay only for water- <br />oriented uses or minor fill for improving shoreline appearance or public access. <br />C01-03cont. <br />C01-04
