RECOMMENDATIONS

The
used for
include:

findings of the hydrologic and hydraulic investigations can be
a number of floodplain management activities. These activities

*Imp1ementation of floodplain zoning.
*Floodproofing structures.
*Sizing stream crossings and bridges.
*Preparation of a flood control feasibility analysis.
*Pub1ic awareness of flood problems.

By authority vested in Section 30-28-111 of the Colorado Revised
Statutes for county governments and Section 31-23-201 for municipal
governments , the cities, towns, and counties within the study area may
enact certain flood-related controls and regulations

"...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 channel 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 "

Therefore, upon official approval of this report by the Colorado
Water Conservation Board, the areas described as being innundated by the
lOa-year flood can be designated as flood hazard areas and their use
regulated accordingly by the local agencies. It is recommended that such
regulation be enacted upon such designation.

Following acceptance of this study, the Town of Oak Creek may
request to be converted from the Emergency Phase of the National Flood
Insurance Program to the Regular Phase through the "special conversion
provision" of the program. It is recommended that the results of this
study be incorporated into any new Flood Insurance Rate Maps (FIRM's) put
out by the Federal Emergency Management Agency, Federal Insurance
Administration for this area. Specifically, the "Flooded Areas Maps" in
this report could be used to replace the flood hazard boundary as shown
in the Federal Emergency Management Agency's Flood Hazard Boundary Map of
December 19,. 1975 (see Exhibit 2). Upon Oak Creek's conversion to the
regular phase of the National Flood Insurance Program, additional amounts
of flood insurance coverage will be available to dwellings within the
lOa-year floodplain. Exhibit 3 gives some information on National Flood
Insurance Program coverage available.

Modification of the existing levee between the railroad bridge over
Oak Creek and Sharp Street to meet Federal Emergency Management Agency
standards would result in a greatly reduced floodplain in the downtown
area. In this report, the existing levee was ignored because it fell
short of FEMA criteria for levees. A cutoff levee at the upstream end of
the existing levee and a widening and raising of the existing levee would
make the' levee meet the standards. State and Federal aid may be
available for such a project.
