PROJECT DESCRIPTION

The D100-00-00-P010 study (Bond ID CI-034) explores the feasibility of channel conveyance improvements along Brays Bayou from Fondren Road to US 59 with additional complimentary considerations to ensure flood risk is not transferred to other areas. This effort concluded in Summer 2022 and includes evaluation of five (5) alternatives to identify the scale of solution that may be required to reduce the flooding risk. The study area is in Harris County Precincts 1 and 4, and the study limits are within the City of Houston. The channel modifications considered in this study effort can be constructed within already available right-of-way but require sizable stormwater detention mitigation volume to avoid causing impacts to other areas. While a detailed detention analysis was performed to determine the total required detention volume for the alternatives recommended, this study did not evaluate specific locations for detention sites due to the high development percentage within the study limits.
