May 19, 2020 – Harris County Commissioners Court approved updates to project details in the 2018 Bond Program List. Update corrects precinct details from Precinct 1 to Precinct 2; funding also adjusted based on CDBG-DR grant award values. Additionally, a $3,511,285 contract was awarded for construction of this project.

April 7, 2020 - Harris County Commissioners Court authorized to negotiate for materials engineering and testing services in support of excavations of stormwater detention basins and associated channel conveyance improvements.

April 7, 2020 - Harris County Commissioners Court approved this project to be advertised for construction bids.

March 10, 2020 - Harris County Commissioners Court approved an agreement between Harris County Community Services and the Flood Control District authorizing the use of 2017 Community Development Block Grant Disaster Recovery Program funds in support of this project.

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 P518-14-00 
  • 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 located east of U.S. 59 and north of Halls Bayou along Tributary P118-14-00, from just north of Langley Road to just north of Hopper Road.


This project is in the DESIGN stage. This stage of the project will result in engineering documents and a bid-ready project manual necessary to take the chosen project into the bidding process and to the CONSTRUCTION stage.

Bond Project Listing

Bond Project C-35 is a potential “Partnership” project. The Flood Control District has applied for a Community Development Block Grant-DR grant in connection with this project. Total allocation for this project is currently $7 million, of which approximately $6.2 million would be partnership funding, if granted, and $800,000 would be local costs. If partnership funds are not available, the project would be funded totally from the 2018 Bond Program as a “Local Only” project.

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.
