Dam, located just downstream of the TOwn of Morrison in Jefferson County. Hydrologic and hydraul,ic analyses of Bear Creek for the revised Flood Insurance Study consider construction of the dam. 2.0 AREA STUDIED 2.1 Scope of Study This Flood Insurance Study covers the incorporated areas of the City of Sheridan, Arapahoe County, Colorado; The area of study is lIhown on the Vicinity Map (~igure 1). Bear Creek was studied by detailed methods along its entire length through Sheridan. The areas studied by detailed methods were selected with priority given to all known flood hazard areas and areas of projected develop- ment or proposed 'construction through 1983. , A hydrologic and hydraulic floqd plain reanalysis has been planned for the South Platte River. Tl\erefore, flooding determined for the South Platte River has beeQ presented in the study as approximate until a reanalysis can be incor;porated into the study. Approximate analyses were used 'to study those areas having a low development potential or minimal f160d hazards. The scope and methods of study were proposed ito, and agreed upon by, FEMA and the City of Sheridan. 2.2 Community Description Sheridan ill located in northwe~tern Arapahoe County, in central Colorado. It is bordered on t~e north by the City and County of Denver, on the east by the qity of Englewood, on the south by the City of Englewood and uriincorporatedareas of Arapahoe County, and on the west by the lei ty and County of Denver.
