FLOOD INSURANCE STUDY
TOWN OF RANGELY, RIO BLANCO COUNTY, COLORADO

1.0 INTRODUCTION

1.1 Purpose of Study

This Flood Insurance Study revises and updates a previous nood
Insurance Study/Flood Insurance Rate Map for the Town of Rangely,
Rio Blanco County, Colorado, published September 27, 1985
(Reference 1). This information will be used by the Town of
Rangely to update existing floodplain regulations as part of the
Regular Phase of the National Flood Insurance Program (NFIP). The
information will also be used by local and regional planners to
further promote sound land use and floodplain development.

In some states or conununities, floodplain management criteria or
regulations may exist that are more restrictive or comprehensive
than the minimum Federal requirements. In such cases, the more
restrictive criteria take precedence and the State (or other
jurisdictional agency) will be able to explain them.
