The Urban Drainage and Flood Control District (UDFCD) was established by the Colorado Legislature in
1969, to assist local governments in the Denver metropolitan area with multi-jurisdictional drainage and
flood control problems. The District covers an area of 1,608 square miles, including Denver, parts of five
surrounding counties, and all or part~ of 33 incorporated cities and towns. A 17 -member board
comprised of locally elected officials and two registered professional engineers. District funds come from
four different property tax mill levies, earmarked for five programs: Master Planning, Design and
Construction, Maintenance, Floodplain Management, and the South Platte River. All but a small percentage
of the 1,600 miles of major drainageways have been mapped (for 1 OO-year floodplain) by the District, and
a complete library of flood hazard delineation studies is maintained at the UDFCD office. The District
assists local governments in the development of flood warning plans and maintains a special notification
program under which over 23,000 informational brochures are mailed to addresses in or adjacent to
identified floodplains.

Other State and Federal Programs
Another research task was to review and summarize existing state and federal programs regarding flood
mitigation and floodplain management. This work was assigned to two subconsultants. Robert Kistner of
Kistner and Associates researched existing state programs and Clancy Philipsborn of the Mitigation
Assistance Corporation investigated existing federal programs. Appendix A of this report lists each state
and federal program, its objective, eligibility requirements, and any partnership opportunities available.

SURVEY QUESTIONNAIRE

Questionnaire Development
To assess the floodplain management and stream rehabilitation problems and concerns across Colorado, a
detailed questionnaire was developed by MWE, CWCB, and the Steering Committee. The questionnaire
solicited data on the fOllowing major subjects.

· Community Profile
· Floodplain Management
o Floodplain Related Issues
o Floodplain Mapping Needs
o Existing/Planned Mitigation Measures
· Multi-Objective Use of Stream Corridors
· Institutional Issues

Based on recommendations from CWCB staff and the Steering Committee, a second questionnaire was
developed for distribution to special districts, environmental organizations and other water related groups,
Complete copies of the original questionnaires sent to Colorado communities and organizations may be
found in Appendix D, with copies of the original mailing lists.
