Major Drainageway Planning for Sand Creek - South Platte River to Towers Road

Sand Creek is located in the Denver metropolitan area and has undergone

several changes due to urbanization. Severe flooding has occurred on Sand

Creek in the past. SLA was contracted to develop the most feasible flood

control plan for Sand Creek.

The scope of services for this study includes review of previous work

completed by the U.S. Army Corps of Engineers, identification of existing

flooding problems and channel stabilization problems, development of alter-

natives to stabilize the channel and reduce the flooding potential, hydraulic

calculations for the selected alternative, and the associated alternative

costs.

In addition, a preliminary design of the selected alternative will be

performed. A more detailed hydraulic analysis will then performed to verify

the reduction of flooding with the proposed alternative. The preliminary

design will consider the sediment transport rates within Sand Creek deter-

mining the long-term stable slope of the channel.

Project Period: October 1982 through Present

Project Budget: $28,000
