PROJECT DESCRIPTION

Bond Project C-25 will make channel conveyance improvements and construct a stormwater detention basin to reduce the risk of flooding by taking in excess stormwater during heavy rain events and then releasing it slowly back to the channel when the threat of flooding has passed.

The stormwater detention basin is anticipated to hold 180 acre-feet, or nearly 58.7 million gallons, of stormwater that might otherwise flood homes and businesses. The stormwater detention basin is designed to be a wet-bottom with a vegetated shelf.

North of the stormwater detention basin, Tributary P118-21-00 will be shifted west and enlarged. Along Aldine Mail Route Road and north of the road, the channel will be extended as a box culvert system to the Western Homes subdivision.

Bond Project C-25 will work in conjunction with two proposed Harris County Engineering Department projects: neighborhood drainage improvements in the Western Homes subdivision and proposed roadway and drainage improvements along Aldine Mail Road.

P518-07-00: Future site of proposed Stormwater Detention Basin expansion, currently managed by TxDOT.

This project is part the Watershed-Wide Project Implementation Program for Halls Bayou.

Location

This project will be located along channel P118-21-00, from Halls Bayou to just north of Aldine Mail Route Road.

Stage

This project is currently in the FINAL DESIGN stage. The CONSTRUCTION stage is expected to begin in the summer of 2021.
