This report comprises the results of an investigation of the flood problem along Clear Creek which flows through or along Brazoria, Fort Bend, Galveston, and Harris Counties. It was found that: a) flooding of Clear Creek causes extensive damages to existing residential development: standard project flood damages are estimated at $5,532,000 and average annual damages are estimated at $ 578,000; and b) enlargement and rectification of the natural channel of Clear Creek as proposed in the plan presented in this report would eliminate all damages from floods as large as the design flood, estimated to have a recurrence interval of once in 100 years, and materially reduce damages from larger floods; average annual benefits during the life of the project are estimated at $2,127,000, with a benefits to costs ratio of 2.9. Authorization of a Federal project is recommended, with estimates of first costs to the United States at $12,600,000.
