Harris County Starts Channel Rehabilitation Inside Addicks Reservoir to Restore Stormwater Capacity

Harris County Flood Control District has begun channel rehabilitation inside the Addicks Reservoir watershed, mobilizing work that follows a Jan. 20 groundbreaking hosted by Commissioner Lesley Briones, Commissioner Tom Ramsey, and HCFCD officials. The Addicks Reservoir Rehabilitation and Restoration Project carries a $25 million price tag and officials describe it as one of the largest flood infrastructure maintenance efforts to date.

The $25 million project is part of the HCFCD maintenance program voters approved in November 2024 and is framed as a multi-site, multi-year effort to restore stormwater capacity. Precinct 4 materials say the work will repair approximately eight miles of channels, remove sediment, stabilize erosion, and restore flood control capacity within the Addicks Reservoir system. “Commissioner Lesley Briones is committed to creating a flood resilient county that keeps residents safe before, during, and after any storm,” the precinct statement says.

The project builds on the Addicks De-Silt Program first described by the district in 2019, which noted that rainfall within the 138-square-mile Addicks watershed drains along 159 miles of open waterways. The 2019 materials identified principal channels by code, including Langham Creek (U100-00-00), South Mayde Creek (U101-00-00), Bear Creek (U102-00-00), and Horsepen Creek (U106-00-00), and stated the program targets channels for which the District has property rights that drain directly to the federal reservoir.

Historical removal volumes underline the scale of prior work in the watershed: as of July 20, 2020, HCFCD reported removing more than 100,000 cubic yards of silt, sediment, and debris. The district recorded 64,579 tons removed from Langham Creek and 32,298 tons removed from South Mayde Creek, the latter figure equated in district materials to approximately 3,200 dump trucks. Those earlier efforts followed severe sediment loads and erosion after the Tax Day 2016 and Hurricane Harvey storms.

Precise contractor names, segment-by-segment start dates, and a completion schedule were not provided in the Jan. 20 announcement. The 2019 program description also notes that the district coordinates construction and maintenance plans with the U.S. Army Corps of Engineers as appropriate, but current project-level coordination or permitting details have not been published alongside the $25 million launch.

Residents and reporters seeking more information can contact Harris County Precinct 4 at 1001 Preston, Suite 950, Houston, Texas 77002, or by phone at 832-927-4444. HCFCD has identified the Addicks effort within its project listings under the district’s internal project code referenced on its project materials.

Work that began this winter will be measured against past targets to return channels to their design capacity, with the stated aim of strengthening stormwater conveyance out of surrounding neighborhoods and into the federal Addicks reservoir. Officials say the rehabilitation is intended to reduce flood risk by restoring channel sections damaged by years of sedimentation and erosion.
