Thank you for engaging with us.
Yes, the project is expected to reduce street flooding on Pinerock Lane south of the project area. Flooding reductions are anticipated throughout the area, with greater benefits west of Gessner Road than east of Gessner Road.
To view the projected flooding improvements, please visit the Engage Houston project page and select Documents & Downloads. Then open the TIRZ 17 Memorial City Area Detention Basin Presentation and review Slide 15, which shows the proposed 100-year flooding reduction map.
Please note that while the project is designed to significantly reduce flooding, it is not expected to completely eliminate street flooding in this area.

The Engage Houston project website includes the public presentation from January 7, 2026. Slide 18 illustrates the proposed basin footprint in relation to the shaded green school parcel property lines; however, the exhibit is not shown to scale and does not include dimensions in feet.
According to the approved 100% design plans, the minimum distance between the subsurface detention basin structure and the adjacent property lines is approximately:
- 20 feet from the western property line
- 20 feet from the northern property line
- 15 feet from the eastern property line
To help mitigate and monitor potential impacts to adjacent properties during construction, the City plans to conduct pre-construction surveys that include comprehensive visual documentation of nearby properties and existing conditions. In addition, construction monitoring of perimeter surface elevations will be performed throughout basin excavation and construction activities.
For roadway-related construction, pre-construction photographs will also be taken, and City inspectors will be on-site to monitor construction activities and address any concerns that may arise during the project.

Thank you for reaching out with your questions regarding the project.
Project cost and funding information can be found in the public meeting presentation available on the project Engage Houston webpage:
TIRZ 17 Memorial Area Detention Basin Project Page
(Located on the right side of the webpage under “Documents & Downloads.”)
The project is funded through a grant from the Federal Emergency Management Agency (FEMA), along with local sponsors including TIRZ 17 Memorial City Redevelopment Authority and the Harris County Flood Control District (HCFCD). Harris County Precinct 3 has also been supportive of the project, including HCFCD funding participation.
The underground detention basin will be constructed on the Memorial Middle School property, east of Attingham Drive, in the northern portion of the property beneath the current location of the SBMSA baseball fields.
Additionally, a project location map and basin drawing/rendering are included in the public meeting presentation available on the Engage Houston project webpage linked above.
Regards,

Stephane asked about 2 months agoReady...Set...ENGAGE!
The project will reconstruct the following streets as described: full width of Barryknoll Lane from west of Betina to Gessner Road; only the far east side of the northbound lane on Gessner Road from Barryknoll Lane to Kingsride Lane and a roughly 60' full width of Gessner in line with the eastbound lanes of Kingsride Lane; full width of Kingsride Lane from Gessner Road west to the dead end at Memorial Middle School. Then, in regards to street widening (roadway pavement): Barryknoll Lane two west bound lanes will be widened from 10 ft to 11 ft each while the two eastbound lanes remain the same 10 ft width; Gessner Road lanes will not be widened; Kingsride Lane will not be widened. Also, the project will have limited work (typically outside of the curb line) along Vindon Drive from the Memorial Middle School to Hallie Drive.

AMej asked about 2 months agoReady...Set...ENGAGE!
Thank you for your question.
Subsurface detention basins have been constructed in Houston and throughout the surrounding region; however, we are not currently aware of any projects of this size that have been completed by Houston Public Works.
There is a similar, though smaller, reinforced concrete subsurface detention basin that was privately developed near Allen Parkway, east of Montrose Boulevard. While it differs in scale, it reflects the type of approach being used for this project.
We appreciate your interest and are happy to provide additional information as it becomes available.

Thank you for engaging with us regarding the TIRZ 17 Memorial City Area Detention Basin Project.
Based on the current 90% design plans, the subsurface detention basin is estimated to have a surface area of approximately 9.25 acres and an average height of 10.26 feet, resulting in a total detention volume of about 94.9 acre-feet.
We hope this information is helpful. Please feel free to reach out if you have any additional questions.
Sincerely,

Thank you for sharing your concerns regarding the TIRZ 17 Memorial City Area Detention Basin Project. Protecting surrounding neighborhoods, including Fonn Villas and Memorial Meadows, is a top priority, and this project is specifically designed to help reduce flood risk in the area.
The proposed detention basin will be located underground and includes several features to help prevent sediment buildup and maintenance issues. A pretreatment chamber will capture and trap dirt and debris before stormwater enters the main storage area, helping the system operate efficiently. The facility will also include an access lid so maintenance crews and equipment can safely perform routine inspections and cleanout.
The City of Houston will conduct regular maintenance at appropriate intervals, including the use of vacuum trucks to remove accumulated sediment and ensure the system continues to function as designed.
The basin is engineered to temporarily store stormwater runoff and release it gradually, reducing peak flows during heavy rainfall events and lowering the risk of flooding for nearby communities.
We appreciate community feedback and remain committed to keeping residents informed as the project progresses.

Thank you for staying engaged regarding the TIRZ 17 Memorial City Area Detention Basin project. Residents have requested that work impacting Kingsride be reconsidered. Widening Bidin or Vinson Street would provide greater benefit to neighborhood traffic flow than widening a dead-end street such as Kingsride.

Thank you for staying engaged regarding the TIRZ 17 Memorial City Area Detention Basin project. The project is seeking to limit impacts to trees within the work limits, and the current design does not include tree removal on Kingsride, except near the dead-end side by the school.

Why This Project Matters
Reduces neighborhood flooding in the Memorial area
The TIRZ 17 Memorial Area Detention Basin is designed to hold a large volume of stormwater during heavy rains, then slowly release it back into the system. That extra storage helps lower water levels in nearby storm sewers and channels, reducing the risk of homes, businesses, schools, and medical facilities flooding in and around Memorial City.Protects a major regional hub, not just one street
Memorial City is a dense corridor of hospitals, shopping, offices, and neighborhoods right along I-10. This detention basin is a regional project—engineered to take pressure off multiple drainage systems feeding into the area, not just fix one localized problem spot.Uses hard-won hazard mitigation dollars wisely
After Hurricane Harvey, FEMA hazard mitigation funds were awarded to only a handful of major Houston flood-reduction projects. The TIRZ 17 basin is one of them, meaning federal dollars are being leveraged with local TIRZ funds to deliver long-term protection that would have taken many more years to build otherwise.Builds long-term resilience into the drainage system
By pairing a large sub-surface detention basin with upstream conveyance improvements, this project helps the system handle more intense storms that are becoming more common in Houston—supporting safer streets, drier homes, and a stronger tax base for the long run.
