F-88 Westador Stormwater Detention Basin K500-27-00

Recent Actions

October 13, 2020 – Harris County Commissioners Court approved a partnership project for the construction of the Westador Stormwater Detention Basin with no funds required by the district.

September 15, 2020 – Harris County Commissioners Court authorized adding the K500-27-00 Unit Number to the Flood Control District stormwater management system for identification purposes.

August 11, 2020 – Harris County Commissioners Court has authorized negotiations to begin with the Westador Municipal Utility District for a partnership project for this stormwater detention basin.

Project Description

The purpose of this project is to construct a stormwater detention basin on the main stem of Cypress Creek. Stormwater detention basins reduce flooding risks and damages during heavy rain events by safely storing excess stormwater and slowly releasing it back to the creek when the flooding has passed. A multi-phased engineering, design and construction approach is expected to begin in the Westador neighborhood. Tentatively, the Westador Stormwater Detention Basin will store approximately 1,100 acre-feet (more than 358 million gallons) of stormwater.

This is one of several stormwater detention projects the Flood Control District is developing in the Cypress Creek watershed. A regional drainage study for the watershed found that flooding along tributaries of Cypress Creek is predominately caused by stormwater from a rising Cypress Creek backing up into tributaries, rather than a lack of sufficient stormwater conveyance/drainage capacity on the tributaries themselves. Therefore, stormwater detention basins could be a beneficial project to reduce that backwater issue.

The regional drainage study described here recommends nearly 25,000 acre-feet of additional stormwater detention in the watershed.

Public Information Session

The T.C. Jester Stormwater Detention Basin and the Westador Stormwater Detention Basin are both included in applications for federal funding through the Community Development Block Grant for Mitigation (CDBG-MIT) Program. A virtual Public Information Session to discuss both projects was held on:

Date: Tuesday, September 22, 2020
Time: 6:30 p.m. to 7:30 p.m.

The official public comment period for the CDBG-MIT applications will be open from October 3 – October 16, 2020. We encourage residents to learn more about the application process, submit a comment and view the meeting presentation and video:
