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 will be 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.
