FLOOD INSURANCE STUDY

1.0 INTRODUCTION

1.1 Purpose of Study

This Flood Insurance Study investigates the existence and severity
of flood hazards in the City of Black Hawk, Gilpin County, Colorado,
and aids in the administration of the National Flood Insurance
Act of 1968 and the Flood Disaster Protection Act of 1973. This
study will- be used to convert the City of Black Hawk to the regular
program of flood insurance by the Federal Emergency Management
Agency (FEMA). Local and regional planners will use this study
in their efforts to promote sound flood plain management.

This Flood Insurance Study was prepared by compiling existing
hydrologic and hydraulic t~chnical and scientific data prepared
by other organization(s) originally for purposes other than the
National Flood Insurance Program (NFIP). The data were identified
as the best available at the time of compilation of this Flood
Insurance Study and should depict the general conditions of the
flooding sources with relative accuracy. FEMA performed a cursory
review and accepted the data as valid for purposes of this Flood
Insurance Study and the NFIP. However, if better information
is known to exist or has been developed since the date of this
report, the information should be immediately forwarded to the
Natural and Technological Hazards Division, FEMA, Building 710,
Denver Federal Center, Lakewood, Colorado 80225, for consideration
for revision of this study.

In some States or communities, flood plain management criteria
or regulations may exist that are more restrictive or comprehensive
than those on which this federally supported study is based.
These criteria take precedence over the minimum Federal criteria
for purposes of regulating development in the flood plain, as
set forth in the Code of Federal Regulations at 44 CFR, 60.3(c).
In such cases, however, it shall be understood that the State
(or other jurisdictional agency) shall be able to explain these
requirements and criteria.
