between Lowry Air Force Base (AFB) and Sand Creek.

The construction of the Kelly Road dam and detention

pond was recommended to alleviate the run-off from

the large paved areas of the AFB. As a result of this

report, construction of Kelly Road dam was completed

in November, 1953.

stormwater from the area south of the AFB to the

lower drainage basin, and the inadequacy of drainage

capacity in the lower basin, were not resolved.

November, 1971. "Adequacy Report, Kelly Road Detention

Dam" (Omaha District, Corps of Engineers) .

The report concluded that by 1985 urban development

upstream of Kelly Road will have lowered the protection

level of the detention structure to a lO-year frequency.

June, 1973. "Analysis Concerning Import of Storm Sewer

Proposals by City of Aurora on Drainage Within Boundaries

of Lowry Air Force Base" (Omaha District, Corps of

Engineers) .

Two proposals for storm sewer construction by Aurora

affecting drainage conditions on Lowry Air Force Base

were reviewed. One proposal for the diversion of a

drainage area into the AFB was not acceptable because

of the imposition of a demand on the Kelly Road dam

storage capacity which it is not designed to handle.

The other proposal for construction of storm drains

within the area contiguous to the AFB is viewed nega-

tively; however, it is recognized that there is no

authority to prevent the drain systems from being con-

structed.

December, 1971. "Reconnaissance Investigation, Westerly

Creek, Colorado" (Omaha District, Corps of Engineers).

The report found that a potential project consisting

of detention storage above the Highline Canal and

channel improvement from East Alameda Avenue to the

confluence of Westerly Creek with Sand Creek would

economically relieve existing and potential flood

problems in the drainage basin. The report recommenda-

tions were not implemented.

April, 1973. "Master Drainage Plan, Aurora, Colorado"

(Nelson, Haley, Patterson & Quirk, Inc.).

Proposed flood water conveyance and detention facilities

for the city of Aurora are described in detail in this

report. However, the problems associated with conveying

October, 1973. "Preliminary Analysis for Urban Drainage

Master Planning of the Highline Canal" (Leonard Rice

Consulting Water Engineers, Inc.).

This report, as it pertains to Westerly Creek, demon-

strated that there is essentially no drainage capacity

in the Highline Canal (primarily an irrigation facility)

for Westerly Creek flows because of inflow to the canal

from other basins.
