In this approacn, affected pro- <br />pertyowners arerelocateo at the public's expense, tnestructuresremoved, <br />and the floodplain returned to a more natural regime. <br /> <br />rne structures determined to be within the designated floodway defined by the <br />flood Hazard Area Delineation report for Cle<lrCreek (Reference 1) ar"the <br />Recreation Center, tne Library, City Hall/Munlcival Building, the MitChell <br />School Annex ano a I'ortion of tne trdiler court on the north side of Clear <br />Creek aas t of Ford Street.

Certain items weN considered movea.ble (mooile homes for example) <br />and costs for r,;location were assign,;d accordingly. <br /> <br />Ii the City of Golden were to consider this approach, impl~entation could <br />proceed In a. phased manner, using a priority basis to remove the most affec- <br />ted structures first. Purchase of other structures could be com~leted when <br />fEMA dalllage payments are made after a major flood, pro~ ideo they are co~ereo <br />oytlood lnsurance. 1J5ing this approach, the capital expenditure for the <br />rem~inin9 structure; could be reduc"o oy an est imateo 20 to 40 percent. <br /> <br />FLOOD WARN1NG SYSTEM <br />Establishment of an early warning system woulD Denefit tne entire study <br />ar€a.
