Project Location

Canon City is located approximately 35 miles west of Pueblo on U.S. Hwy. 50. The west side of
the city is bounded by two hogbacks which run north-south. The higher and western-most of
these two hogbacks rises approximately 350 feet above surrounding ground and its serrated ridge
is traversed by the well known Skyline Drive. The proposed project consists of seven (7) small
detention ponds (one of which is an existing structure) to be constructed by placing low height
dams across openings in the lower, eastern hogback at the seven locations shown on Figure ll-2
of Section II.

Problem Description

Currently, stormwater flows exit through openings in the lower, eastern-most hogback and
regularly overwhelm collection facilities in the historic downtown and adjacent residential areas.
Further, because of the steep, undeveloped nature of the tributary drainage basins, stormwater
flows carry substantial amounts of sediment. This material ultimately deposits on City streets
and in stormwater collection facilities exacerbating flooding and necessitating regular cleanup
and repairs.

Federal Disaster Declaration

The project is entirely within the federally declared disaster area for disaster # DR-l 186-CO.

Damage Survey Reports

Information on DSR's for the 1997 flood disaster have not been included in this report.
