Colorado Water Conservation Board Designation

concerning the designation of the flood plain, the Colorado Water
Conservation Board is charged with the primary responsibility for:
1. Making recommendations to local governments and the
Colorado Land Use Commission.
2. Providing technical assistance to local governments.
The Board's power and duty is...
_..to devise and formulate methods, means and plans for
bringing about the greater utili~ation of the waters of
the state and prevention of flood damages therefrom, and
to designate and approve storm or floodwater runoff
channels or basins, and to make such designations
available to legislative bodies of cities and
incorporated towns, to county planning commissions,
and to boards of adjustment of cities, incorporated
towns, and counties of this state"..

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

Upon review and approval of this report, the Colorado Water
Conservation Board will designate and approve as flood plain areas
those areas inundated by the 100-year flood as described by the
floodwater surface elevations and profiles in this report. The use of
the designated flood plain areas may then be regulated by the local
government.

Model Regulations

Model flood pla~n regulatio~s have been promulgated by the Colorado
Water Conservatlon Board, wlth the purpose to promote pUblic health
safety, an~ general welfare, and minimize flood hazards and lo~ses '
The model lncludes provisions designed to: ~ .
1. P~omote sound planning and permit only such uses
wlthin flood pla~ns that will not endanger life,
healt~, and publlC safety or property in times of
floodlng.
2. Protect the public from avoidable finanoial
eXP7nditures for flood control projects, flood
rellef measures, and the repair and restoration
of damaged public facilities.
3. Prevent avoidable interruption of business and
commerce.
4. Minimize victimization of unwary home and land

5. Facilitate the administration of flood hazard aroas
by establishing requirements that must be met before
use or development is permitted.
The Board's model flood plain regulations offer two options for
management of the lOO-year flood plain. These are the Hazard Area
Concept and the Floodway Concept.
The Hazard Area concept defines the areas of the flood plain in Which
waters of the lOO-year flood attain a maximum depth greater than one
""", O"he-half feet as a high hazard area, and a depth less than this as
a ow azard area.

The Flood~ay concept defines the channel of a stream and adJacent
flood plaln areas that must be kept free of development in order to
safely pass the lOO-year flood with a minimal rise in the water
',urrace elevation. The rise must be no more than one foot to _nat
ederal standards. "'~~
