- PREFACE -

Upon acceptance of this report by the Urban Drainage & Flood Control Dis-

trict 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.

Authorization

I

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

It should be noted that the terms "Intermediate Regional Flood," "100-

year Flood," and "one percent flood" can be used interchangeably as

they are all defined by the same type of flood event.

Purpose and Scope

I

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 legislative bodies of cities and incor-
porated towns; to county planning commissions; and
to boards of adjustment of cities; incorporated towns;
and counties of this state. .."

This report was prepared for the guidance of local officials in plan-

ning the use and regulation of the flood plain. The report includes in-

formation on historical floods and the nature and extent of probable

future floods which can be reasonably expected on the respective study

reaches. The 100-year flood should be given appropriate consideration

before planning for development in the flood plain.

I

I

as stated in Section 37-60-106 (1) (c) of the Colorado Revised Statutes
1973. The cities, incorporated towns and counties within the study
area may provide zoning regulations ...

I

"...to establish, regulate, restrict, and limit 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
Conservation Board, in order to lessen or avoid the
hazards to persons and damage to property resulting from
the accumulation of storm or floodwaters "

The 100-year flood plain is shown on the Flood Hazard Area Delineation

Maps which delineate the areaS that would be inundated by such an event.

Flood profiles show the water depths relative to the ground line. Eleva-

tion reference data is given that can be applied across the full width

of the drainageway. Typical cross sections are presented to indicate

ground level across the drainageway at specified locations and the over-

lying 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.
