1.0 INTRODUCTION

1.1 Purpose of Study

The purpose of this Flood Insurance Study is LO investigate the
existence and severity of flood hazards in the Town of Silver Plume,
Clear Creek County, Colorado, and to aid in the administration of
the National Flood Insurance Act of 1968 and the Flood Disaster
Protection Act of 1973. Initial use of this information will be to
convert Silver plume to the regular program of flood insurance by
the Federal Insurance Administration. Further use of the informa-
tion will be made by local and regional planners in their efforts to
promote sound land use and flood plain development.

1.2 Coordination

In a meeting held on August 16, 1976, city officials were a~guainted
with the National Flood Insurance Program and informed of the pro-
gress of the study.

Meetings between representatives of Black & Veatch, consulting
Engineers (the study contractor), and the Federal Insurance Adminis-
tration took place on June 17, 1977, and July 7, 1977. These meetings
were held to discuss the hydrology of Clear Creek County and the
hydraulics of the Silver Plume Flood Insurance Study.

The U.S. Geological Survey, the Colorado Water Conservation Board,
the U.s. Forest Service, the Community Desigl! Ce~ter in Denver, and
the Colorado Department of Highways were also contacted.

On October 11, 1977, this Flood Insurance Study was reviewed at the
final coordination meeting attended by personnel of the Federal
Insurance Administration and the study contractor, as well as members
of the community. No additions or corrections to the study were
deemed necessary.
