BEAR CREEK

the City of Denver to a location approximately 3,500 feet down-
stream from South Wadsworth Boulevard. From here to South
Wadsworth Boulevard, the creek essentially forms the boundaries
of the City of Denver (on the north) and City of Lakewood (on the
South), as shown on Sheet 1. From South Wadsworth Boulevard to a
point approximately 2,000 feet upstream of South Kipling Street,
the Bear Creek floodplain is entirely wi thin the City of Lakewood.
Upstream of this boundary to the study limit at Bear Creek Dam,
the floodplain is in Jefferson County (Sheet 1).

- AUTHORIZATION -

This report WaS authorized and contracted through the Urban
Drainage and Flood Control District as part of a program of iden-
tifying floodprone areas within the District's jurisdiction.

This study identifies floodprone areas along Bear Creek with-
in the Cities of Sheridan, Denver and Lakewood, and Jefferson
County. This floodplain information, along with the floodplain
mapping, are currently made available to the public and to local
governing agencies for the purpose of adopting their own flood-
plain management programs.

Upon acceptance of this report by the Urban Drainage and Flood
Control District, and the designation and approval of the flood
hazard areas by the Colorado Water Conservation Board, this study
can be used by local governing bodies to regulate floodplains and
as a guide for future drainageway improvements along the Bear Creek
channel.

Included in this report are Flood Hazard Area Maps which
show the areas that would be flooded by a potential 100-year event.
The water surface profile shows the elevations of flood flows re-
lated to Mean Sea Level (MSL) Datum.

A floodway was also computed to designate those areas that
must be kept free of encroachment to convey the 100-year flood
event along Bear Creek without causing serious damage to the com-
munity.

- SCOPE OF WORK -

The flood profile and flooded areas presented are based on
fully developed basin conditions considering present channel devel-
opment. Flood water surface elevations and floodplain boundaries
are often revised by road and bridge construction, floodplain de-
velopment, flood control improvements, or natural processes.
Prior to utilization of this report for planning or design purposes,
the user is advised to contact the Urban Drainage and Flood Control
District to determine if the information in this report has been
amended.

The scope of work in this study was prepared under the current
format of the District's Flood Hazard Area Delineation Reports.

This study consists of a floodplain analysis for a 100-year
flood event along the study reach of Bear Creek. This study reach
extends westward from the confluence with the South Platte River
in the City of Sheridan to the recently constructed Bear Creek Dam,
a distance of approximately 8.2 miles.

The Bear Creek floodplain is in the City of Sheridan from its
junction with the South Platte River to a point just upstream of
South Lowell Boulevard. Continuing upstream, the floodplain is in
