The Houston City Council on October 22 approved an interlocal agreement for Phase 2 of the Meyergrove Stormwater Detention Basin Project, a key initiative aimed at reducing street flooding in southwest Houston, particularly near North Braeswood Boulevard and Frankway Drive.
The project, led by the Harris County Flood Control District (HCFCD) in partnership with the city, follows the recent completion of Phase 1 and is designed to add approximately 8.1 acre-feet of additional stormwater storage. One acre-foot equals roughly 325,851 gallons, meaning the new phase will provide capacity for about 2.6 million gallons of runoff.
Location and Previous Phase
Phase 2 of the basin will be built just west of the existing detention area, inside the I-610 Loop and between the current basin footprint and Brays Bayou. The first phase delivered 80 acre-feet of storage—around 27 million gallons—and included recreational trails and benches as part of its community-friendly design.
Council member Abbie Kamin noted during the meeting that the project exemplifies “the type of city-county partnership where we’re improving flood mitigation but also quality of life.”
What Residents Can Expect — and When
City engineers report that the design for Phase 2 is nearly complete, with construction expected to break ground in mid-2026, pending final approval from the Harris County Commissioner’s Court. Once operational, this additional storage capacity will provide critical relief during intense rainfall, reducing flood risks in neighborhoods that have historically experienced frequent street flooding.
Why This Matters for Southwest Houston
-
Improved flood resilience: The neighborhoods served by this basin—inside the 610 Loop and north of Brays Bayou—are vulnerable to heavy rainfall and bayou overflow. The added detention volume will reduce the amount of water entering the bayou system during high-intensity storms.
-
Urban growth context: As southwest Houston continues to grow, increased development adds impervious surfaces, raising runoff levels. Expanding stormwater detention is essential to offset that growth.
-
Public-space benefits: Phase 1 integrated recreational elements such as trails and benches, turning stormwater infrastructure into multi-use community space. Phase 2 is expected to follow a similar approach.
-
Collaborative funding: The project highlights cooperation between the City of Houston and HCFCD, utilizing county bond funds, federal grants, and city coordination.
Funding and Project Scope
Phase 1 began in February 2024 at a cost of about $19 million, supported by federal funding and the 2018 HCFCD bond program. For Phase 2, approximately $1 million in secured funding has already been earmarked.
The additional 8.1 acre-feet of storage is smaller than Phase 1 but strategically designed to address specific high-risk streets and to close a drainage gap within the Brays Bayou watershed.
Challenges and Considerations
-
Construction disruptions: Nearby residents should expect temporary inconveniences such as noise, traffic adjustments, and equipment staging.
-
Maintenance needs: Long-term success depends on consistent upkeep, sediment management, and vegetation control.
-
Community expectations: While the basin will reduce flood risk, residents may still experience occasional street flooding during extreme events. Managing expectations will be key.
-
Future funding: If successful, this project could pave the way for additional phases, contingent on available funds and inter-agency alignment.
Broader Context — Why Houston Is Investing
Given Houston’s low-lying geography and history of severe storms, detention basins are essential tools in the city’s flood-mitigation strategy. Projects like the Meyergrove Basin form part of a broader effort across Brays Bayou and other watersheds to reduce the impact of major rain events, which are projected to grow more frequent with changing climate patterns.

Looking Ahead
For residents of southwest Houston neighborhoods bordering Brays Bayou, the Phase 2 detention basin represents a meaningful investment in long-term safety and infrastructure resilience. As work progresses, city and county leaders will emphasize transparency, community communication, and continued focus on multi-use design to ensure both practical and quality-of-life benefits.
This project reflects a broader shift in Houston’s approach to infrastructure — one that treats flood control not only as engineering, but as community investment. When Phase 2 breaks ground in 2026, it will mark another milestone in the city’s ongoing commitment to reducing flood risks while building public spaces that serve the people who live there.
