<br />,-- <br /> <br />EL PASO COUNTJI' <br /> <br />-------. <br /> <br />- <br /> <br />--- <br /> <br />"" <br /> <br />CITY OF COLORADO SPRINGS - DRAINAGE CRITERIA MANUAL <br /> <br />HDR developed a new drainage criteria manual for the city of Colorado Springs and El Paso County, <br />Colorado. The Colorado Springs metropolitan area experienced tremendous growth during recent <br />years (population 400,000) and experienced serious drainage problems. The drainage manual <br />included drainage policy, ordinances/ resolutions, drainage financing, drainage criteria, engineering <br />methods, design examples and a computer program for implementation. The manual development <br />represented a unique joint effort between the city and county. HDR evaluated the existing drainage <br />policies and criteria in use both in the city and county, and develop a new uniform set of drainage <br />standards. State-of-the-art drainage procedures across the county and in the Colorado front range <br />area were reviewed for application to the Colorado Springs area. The manual was completed and <br />presented in more than 15 public forums in the area before adoption by the city council and county <br />commissioners. The successful adoption process took six months in addition to the eight-month <br />development period for the manual. <br /> <br />Client: City of Colorado Springs <br /> <br />Net Fees: $100,000 <br /> <br />Location: Colorado Springs, CO <br /> <br />CITY OF COLORADO SPRINGS - ORION DRIVE STORM SEWER/CHANNEL <br />OUTFALL <br /> <br />HDR designed improvements for a major drainage project on Orion Drive for the city of Colorado <br />Springs. This project included designing 1,829 m (6,000 ft) of new storm sewer :md outfall channel <br />within the Gardiner Gulch drainage, a major tributary to the Bear Creek drainageway. The study area <br />lacked a storm sewer system and the existing outfall channel was severely under design capacity. <br />The site-specific investigation included evaluation of three major drainage control alternatives (all <br />governed by an off-site runoff issue), the t:valuation of several existing major utility concerns, and <br />the investigation of non-uniform street gt:ometries that account for major flow splits within th(~ <br />residential area. <br /> <br />Client.
