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 IOO-year flood hazard areas. Approval of the <br />proposed general plan element amendments would not facilitate <br />development within 10O-year flood hazard areas or increase flood <br />hazards in the City. <br /> <br />J. <br /> <br />Result in significant alteration of receiving water quality <br />during or following construction. <br /> <br />K. <br /> <br />Could the proposed project result in increased erosion <br />downstream? <br /> <br />No Impact <br /> <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. The proposed general plan amendments would <br />establish policies to minimize erosion and sedimentation <br />impacts. Additionally, approval of the proposed general plan <br />element amendments would not result in erosion impacts, in that <br />the proposed amendments would not involve any construction <br />activities that would disturb or uncover soils to facilitate <br />erosion impacts. <br /> <br />13 <br /> <br />7~tj~~fi <br />
