Stormwater Detention Basins
Four stormwater detention basins have been created to hold approximately 3.5 billion gallons of stormwater and cover about 900 acres. A stormwater detention basin is an area where excess stormwater is stored until the water level in the channel recedes, allowing the stormwater to flow away safely.
Approximately 21 miles of the channel has been modified to increase the amount of stormwater the bayou can carry. Beginning at the mouth of Brays, the channel has been widened 18 miles west to Fondren Road. An additional six miles of the channel was widened and deepened, beginning downstream of Old Westheimer Road (renamed West Houston Center Blvd) and continuing upstream to Highway 6.
Bridge Modifications / Extensions / Replacements
Modifications/extensions/replacements will be made to 32 bridges along Brays Bayou to allow for increase in bayou flow.
