Valley cross sections are presented to indicate ground level across the valley at specified locations and the overlying flood depths. The flood profiles and flooded area data presented are based on future, developed conditions in the basin as determined from current master planning maps. possible future improvements to control floods are not a consideration of this report. The report provides supplemental information to the Flood In- surance Study for Arapahoe County, prepared for the Federal Insurance Administration. - STUDY AREA DESCRIPTION - Community Description The report was prepared by Gingery Associates, Inc., Consulting Engineers, Englewood, Colorado, at the request of the Urban Drainage & Flood Control District. Arapahoe County is located in central Colorado, just south and east of Denver, the State capitol. The general physical boun- dary is that of a rectangle 12 miles by 72 miles, which extends from near the foothills of the Rocky Mountains to the open plains of eastern Colorado, covering approximately 864 square miles. ~rapahoe County was the first designated county in the state even though at that time, the county, which comprised over one-fifth of the present State of Colorado, was the western part of the Kansas Territory. From then (1858) until April of 1903, the County changed shape and size many times and on two occasions was non-existent. During the early days of expansion and exploration, Arapahoe County was visited by many explorers and trappers until gold was discovered at the mouth of Little Dry Creek, after which intensive growth was experienced throughout the region. The territory in and around Arapahoe County also be- came known as one of the greatest cattle ranch areas in the west. With the advent of the railroads, towns like Deer Trail became the natural termination points for cattle drives originating in Texas. The information in this report does not imply any State action to zone or regulate use of the flood plains. The District has the authority to regulate flood plains, but to date has chosen to leave flood plain regulation responsibility with local governments. The report provides a suitable basis for the adoption of land use controls to guide flood plain management, with consideration for environmental attributes, and thereby prevent intensification of flood losses.
