Additional project elements, including the P518-14-01 stormwater detention basin, were added in 2017 to an existing project to design the P518-10-00 stormwater detention basin as well as channel conveyance improvements to Tributary P118-14-00.

Project Description

This project involves several components to improve the conveyance of stormwater and to reduce flooding risks in this area: 

  • Excavation of Little York Stormwater Detention Basin, HCFCD Unit P518-10-00 
  • Excavation of Hopper Stormwater Detention Basin, HCFCD Unit P518-14-01 
  • And related channel conveyance improvements to Tributary P118-14-00 

Stormwater detention basins reduce flooding risks and damages during heavy rain events by safely storing excess stormwater and slowly releasing it back to the bayou when the threat of flooding has passed.

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


This project is located east of U.S. 59 and north of Halls Bayou along channel P118-14-00, from just north of Langley Road to just north of Hopper Road.


This project is under CONSTRUCTION.

The map will be updated when projects advance or when more information becomes available.

Project Lifecycle

Every flood damage reduction project is unique. Yet each project begins and ends, with common and predictable milestones along the way. Whether a project moves forward – and how quickly – depends on many factors, including the availability of funding at each milestone, shifting community priorities for flood damage reduction, and other changing circumstances (such as the price of trees or concrete) from year to year.



A Community Engagement Meeting for this project was held on Wednesday, September 18, 2019, from 6-8 p.m. at North East Community Center, 10918 Bentley Street, Houston, Texas 77093.
