No Impact <br />The City of Santa Ana is a participant in the National Flood <br />Insurance Program (NFIP). Communities participating in the NFIP <br />must adopt and enforce minimum floodplain management standards, <br />including identification of flood hazards and flood risks. <br />Participation in the NFIP allows communities to purchase low <br />cost insurance protection against losses from flooding. The <br />flood hazards in the City are depicted on Flood Insurance Rate <br />Maps. The Flood Rate Insurance Maps indicate that portions of <br />the City are within 100-year flood hazard areas. Approval of the <br />proposed general plan element amendments would not facilitate <br />development within 100-year flood hazard areas or increase flood <br />hazards in the City. <br />J. Result in significant alteration of receiving water quality <br />during or following construction. <br />K. Could the proposed project result in increased erosion <br />downstream? <br />No Impact <br />Erosion refers to the removal of soil from exposed bedrock <br />surfaces by water or wind. The effects of erosion are <br />intensified with an increase in slope, the narrowing of runoff <br />channels and by the removal of groundcover, which leaves the <br />soil exposed. Approval of the proposed general plan element <br />amendments would not result in erosion impacts, in that the <br />proposed amendments would not involve any construction <br />activities that would disturb or uncover soils to facilitate <br />erosion impacts. <br />O. Tributary to other environmentally sensitive areas? If so, <br />can it exacerbate already existing sensitive conditions? <br />P. Have a potentially significant environmental impact or <br />surface water quality to either marine, fresh or wetland <br />waters? <br />S. Impact aquatic, wetland or riparian habitat? <br />Less Than Significant Impact <br />According to the City's General Plan Land Use Element EIR, there <br />are no sensitive marine waters, fresh waters or wetlands in the <br />City. However, the City does contain several drainage systems <br />14 <br />75C-52 <br />
