Plan Evaluation

The components of the selected plan have been combined into

four groups: flood storage facilities on Lowry Air Force Base;

channel improvements downstream from Kelly Road Dam; drainage

improvements upstream from Lowry Air Force Base; and flood plain

management including an emergency evacuation plan and flood

insurance downstream from Kelly Road Dam. The flood storage

facilities on Lowry Air Force Base would be Federal responsi-

bilities, and the upstream and downstream improvements and flood

plain management would be local responSibilities. Only the flood

storage and the downstream components were evaluated. Drainage

improvements upstream were not evaluated because they would not

obviate the need for flood control improvements on Lowry Air

Force Base or the downstream channel improvements. They are not

a prerequisite for the Federal action. The benefits for the

drainage improvements were, however, assumed to be equal to the

costs,

CONTRIBUTION TO PLAN OBJECTIVES

The contribution of each group of plan components to the plan

objectives is presented in table 6. The flood storage component

would assure the safety of Kelly Road Dam, reduce the flood

hazard in the downstream area, and provide for the storage of

runoff from the upstream area. The channel improvements and

flood plain regulations would reduce the flood hazard downstream.

Although emergency evacuation would not significantly reduce the

flood damages, it would reduce the loss of life potential which
