<br />2.0 AREA STUDIED <br /> <br />2.1 Scope of Study <br /> <br />This Flood Insurance Study cov~rs the incorporated areas of the <br />City of Federal Heights, Adams; County, Colorado. The area of study <br />is shown on the Vicinity Map <;Figure 1). <br /> <br />Tributary M of Niver Creek was; studied in detail from the corporate <br />limits at Pecos Street upstream 5,640 feet to a point 350 feet <br />above Elm Court. <br /> <br />The areas studied by detailed methods were selected with priority <br />given to all known flood hazar~ areas and areas of projected develop- <br />ment or proposed construction through July 1989. <br /> <br />The scope of this study set fO,rth by FEMA required only that the <br />10- and 100-year recurrence interval floods be studied by detailed <br />methods on Tributary M of Niver Creek. <br /> <br />Niver Creek and Tributary L of' Niver Creek were studied by approximate <br />methods. <br /> <br />Approximate analyses were used: to study those areas having a low- <br />development potential or minimal flood hazards. <br /> <br />2.2 Community Description <br /> <br />The City of Federal Heights is located in west-central Adams County, <br />approximately 5 miles north of, the Denver corporate limits and 1.5 <br />miles east of the Jefferson County line, in central Colorado. Federal <br />Heights is bordered by the Cities of Thornton on the east, Westminister <br />on the west, and Northglenn oni the northeast. <br /> <br />Adams County is one of the ricpest irrigated and dryland farming <br />areas in the country. In add irt ion , the southwestern corner of the <br />county has experienced heavy industrial development. In recent <br />years, the population growth in the county has been rapid, resulting <br />from the urbanization of the Denver metropolitan area and subsequent <br />suburban development. Federal' Heights experienced much growth <br />between 1970, when the populat,ion was 1,502, and 1980, when the <br />, <br />population figure was 7,846 (~ference 2). <br /> <br />Tributary M of Niver Creek flo~ southeasterly through Federal <br />Heights through a series of ov~rland flow areas, culverts, and <br />defined channels and joins Niver Creek, which flows easterly into <br />NOrthfield Creek, which then f~ows northerly into the South Platte <br />River. Niver Creek and Tribut~ry L of Niver Creek also flow <br />southeasterly through Federal Heights, through generally undeveloped <br />areas. <br /> <br />Tributary M of Niver Creek is ~n intermittent stream with two major <br />flooding characteristics: snoWmelt and summer thunderstorms.
