Waller Creek Flood Management and Water Quality Improvements Study

CIP 485-617-5011

Summary

This study developed a flood management plan for the lower Waller Creek watershed (W. 15th to Town Lake). Also, a water quality master plan for the entire Waller Creek watershed was prepared. Architectural review of the proposed improvements will be performed to ensure compatibility.

An 18 foot diameter tunnel from 15th Street to Town Lake, under Trinity Street, is being proposed. The tunnel will divert flood flows from Waller Creek and will provide limited water quality improvements. The proposed project will include pumping of water from the tunnel to Waller Creek at 15th Street to increase base flow. The estimated project cost is $16,800,000. The project's benefit/cost ratio under current conditions is 0.50.

Status

The final report has been submitted. The project will be listed as an unfunded potential C.I.P. project. Employees of the Drainage Utility Department are inquiring with the U.S. Corps of Engineers on their interest in funding the project. (COE funding is unlikely, given the low benefit/cost ratio of the project.)

Description

The details developed by the study will include the costs and economic benefits of the flood management and water quality plan. Evaluation of the plan will indicate the required funding for a future bond election or appropriation.
