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 govemments 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 NOIwood is the San Miguel County and Incorporated Areas
AS, dated September 30. However, a previous Flood Hazard Boundary Map (FHBM), dated
November 22, 1974, was prepared which showed Special Flood Hazard Areas for the town. As
part of NOIwood's entry into the National Flood Insurance Program (NFIP) in 1985, FEMA
converted the Special Flood Hazard Areas (SFHA) to a No Special Flood Hazard Area (NSFHA)
which indicates that the flooded areas are minimally flooded. 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
information, the approximate floodplain delineations shown .on the Norwood 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floodplain areas shown on the FHBM panels will become superseded.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.
