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). A water quality master plan for the entire
Waller Creek watershed was also prepared. Architectural review of the proposed
improvements was conducted to ensure compatibility.
An 18-foot diameter tunnel from 15th Street to Town Lake, under Trinity Street,
is 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 is listed as an unfunded
potential C.I.P. project. Employees of the Watershed Management Department have
reviewed the project with the U.S. Corps of Engineers. COE funding is
unlikely, given the low benefit/cost ratio of the project.
Description
The study includes the costs and economic benefits of the flood management and
water quality plan. The project is not funded. A future bond election would be
required to fund the project.
