This project will develop a stormwater detention basin on approximately 171.5 acres of Flood Control District-owned property at T.C. Jester Boulevard and Cypress Creek, south of Cypresswood Drive.

The purpose of this project is to construct a stormwater detention basin on the main stem of Cypress Creek, which will work to reduce flooding risks and damages during heavy rain events by safely storing excess stormwater and slowly releasing it back to the creek when the threat of flooding has passed. A multi-phased engineering, design and construction approach is expected to begin in the area west of T.C. Jester Boulevard and later expand to include the area east of T.C. Jester Boulevard.

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. (Link to
