PREFACE

Flood water surface elevations and floodplain boundaries are often revi~ed
by road and bridge construction, floodplain d:v:lop~ent, flo?d control Im-
provements or natural processes. Prior to utIlIzatIon of thIs report for.
planning or design purposes, the user is advised to contact ~he Urban Draln=
age & Flood Control District or the Colorado Water ConservatIon Board to de
termine if the information in this report has been amended.

I

This report was authorized by the Urban Drainage and Flood Control District
in joint sponsorship with the Colorado Water Conservation Board. The
District has the power to enact District-wide floodplain regulations. At
present, the District makes floodplain information and mapping available
for local agencies to adopt and administer their own floodplain regulations
with the assistance of the District.

The Colorado Water Conservation Board has the power and duty

I

...to designate and approve storm or floodway runoff channels
or basins, and to make such designations available to legisla-
tive bodies of cities and incorporated towns; to county planning
commissions; and to boards of adjustment of cities; incorporated
towns, and counties of this state....

I

as stated in Section 37-60-106 (1) (c) of the Colorado Revised Statutes
1973.

I

The cities, incorporated towns and counties within the study area
may provide zoning regulations...to establish, regulate, restrict,
and 1 imit such uses on or along any storm or floodwater runoff
channel or basin, as such storm or floodwater runoff or basin has
been designated and approved by the Colorado Water ConservatJon
Board, in order to lessen or avoid the hazards to persons and
damage to property resulting from the accumulation of storm or
floodwaters...

as stated in Section 30-28-111 for the county governments and Section 31-
23-201 for municipal governments of the Colorado Revised Statutes 1973.

I

Upon acceptance of this report by the Urban Drainage and Flood Control
District and the designation and approval of this report by the Colorado
Water Conservation Board, the areas described as being inundated by the
100-year flood (Intermediate Regional Flood) can be designated as flood
hazard areas and their use regulated accordingly.

I

It should be noted that the terms "Intermediate Regional Flood," "100-
Year Flood," and "1 percent flood" can be used interchangeably as they
are all defined by the same type of flood event.

I

The information in this report does not imply any State action to zone or
regulate the use of floodplains. The District has the authority to regu-
late floodplains, but to date has chosen to leave floodplain regulation
responsibil ity with local governments. The report provides a suitable
basis for the adoption of land use controls to guide floodplain manage-
ment, with consideration for environmental attributes, and thereby prevent
intensification of flood losses.
