<br />.. <br /> <br />'27 <br /> <br />. Generation of valuable data and analysis for the development of mitigation plan <br />recommendations. <br />Evaluation of CWCB Floodplain Mapping and Revisions as Needed <br /> <br />. <br /> <br />Presellt Action: <br /> <br />A cursory review and sketch comparison of the flooded area outline to any existing <br />CWCB designated 1 OO-year flood outline is made. Estimates of flood discharges and <br />floodwater elevations are prepared for some flood disasters. <br /> <br />Present Fundill!!: <br /> <br />No mechanism for a fonna! investigation or assessment is in place. <br /> <br />ProDosed Action: <br /> <br />The CWeB, in cooperation with the DNR Division of Purchasing, will develop a <br />standing annual contractual agreement for placing an engineering consulting firm in <br />service on July 1. Contracted services will include evaluation of the CWCB's designated <br />floodplain studies and revisions to mapping, if necessary. Contracting will be perfonned <br />by different finns to prevent conflicts of interest. , Revisions or new mapping will require <br />1) community agreement to proceed, and 2) a fifty percent (50%) cost share by the <br />affected local govemment(s). Any Notice to Proceed will be under the instruction of the <br />CWCB Director. <br /> <br />. <br /> <br />ProDosed Fundin!!: <br /> <br />Establish an annual account within the CWCB's five percent (5%) of the construction <br />fund dedicated to flood projects. Estimated annual budget: $30,000. <br />, <br />; <br /> <br />Benefits: <br /> <br />· Confirmation of precipitation and hydrologic values. <br /> <br />. Verification of hydraulic conditions in a flood and of validity of 100-year flood <br />inundation areas. . <br /> <br />· Re-engineering 100-year floodplain limits, if ~pplicable. <br />, <br /> <br />. Understanding of relative depths of flooding in various parts of the 100-year <br />floodplain to detennine areas subject to the greatest damage. <br /> <br />· Confinnation of the most accurate 1 OO-year designated floodplain boundaries. <br /> <br />. <br />
