PREFACE

This Floodplain Information Report (FIR) is part of a program by the Colorado Water Conservation
Board (CWCB) to make approximate floodplain maps prepared by the Federal Emergency
Management Agency (FEMA) easier for local governments to use. This CWCB report provides
limited engineering information to support the approximate delineations on the FEMA maps, and it
provides floodplain management information to guide the local governments in the use of the maps.

The official floodplain information for Dove Creek is the Flood Hazard Boundary Map (FHBM),
dated November 28, 1975. FEMA converted the FHBM to a Flood Insurance Rate Map (FIRM) on
January I, 1986. The FHBM was prepared by FEMA and contains approximate floodplain
delineations. The approximate floodplains do not include any engineering information to describe
basis of the approximate floodplain mapping. The initial purpose of this report, therefore, is to
provide the Town with limited supporting information for the approximate floodplain delineations.
This FIR includes a description of available hydrologic information for major flooding sources
within or adjacent to the Town. In addition, the FIR gives the Town some basic information about
floodplain management and it provides some alternatives that could be considered in formulating
and implementing floodplain management objectives.

A second function of this report is to assure that the FHBM meets the basic technical requirements
for designation and approval by the CWCB. Without the inclusion of basic engineering
informalion, the approximate floodplain delineations shown on the Dove Creek Flood Hazard
Boundary Maps cannot qualify for CWCB designation. Colorado statutes require that local
governments obtain from the CWCB the designation and approval of floodplain information for its
use in regulatory purposes. This FIR provides a means for the FHBM to meet that statutory
objective. As new and more detailed floodplain information becomes available, the approximate
floodplain areas shown on the FHBM panels will become superseded. The CWCB will designate
and approve new information, and rescind old information as appropriate.
