FBCLID 7 Stormwater Detention Project

September 2023

The Texas Water Development Board (TWDB) recently approved the plans for the FBCLID 7 Stormwater Detention Project. When complete the project will add 115 acre-feet, or 37 million gallons, of additional storage to the FBCLID 7 drainage system. In August 2022, TWDB awarded FBCLID 7 a $324,000 grant and a 0% loan of $10,486,000 to pay for construction of the Stormwater Detention Project. Now that the plans are approved, the public bidding process has started. FBCLID 7 has acquired all property needed to construct the detention pond, and utilities are currently being relocated. Construction is scheduled to start in Fall 2023 and be complete before Summer 2024.

In August 2022, the Texas Water Development Board (TWDB) awarded FBCLID 7 a $324,000 grant and a 0% loan of $10,486,000 to pay for construction of the Stormwater Detention Project. Engineers have completed the design and environmental assessment needed to create 115 acre-feet of additional storage. These engineering and design documents are currently being reviewed by TWDB and require their approval before the public bidding process can being.

Public utilities like electrical lines will also need to be relocated before construction can commence. The District Engineer is actively working on utility relocation agreements while TWDB finishes their review process. FBCLID 7 has also completed all property acquisition required to construct the detention pond as shown below. The current project schedule estimates that the bidding process will begin during the summer of 2023 and the Stormwater Detention Project will be complete by summer 2024.

In response to flooding in the New Territory Community during Hurricane Harvey and increased flood protection requirements, the Board of Directors of Fort Bend County Levee Improvement District No. 7 (FBCLID7) has determined that the District needs to provide for additional stormwater pumpage, detention and drainage capacity to protect the community from future flood events.

The District’s engineer completed a master drainage study which concluded that the following improvements were required to adequately protect the community to recently enacted Atlas 14 flood protection standards:

  • Construction of an additional 115 acre-feet of storage within the District; and
  • Construction of an additional 280,000 gallon-per-minute (GPM) pump station.

This study, titled “Fort Bend County Levee Improvement District No. 7 Master Drainage Plan Update” dated August 17, 2020, was reviewed and approved by the Fort Bend County Drainage District and the City of Sugar Land. This Master Drainage Plan (MDP) can be found on the FBCLID7 website “Documents” page.

To meet the updated flood protection requirements, the FBCLID7 Board approved the construction of a new 280,000 GPM pump station to be constructed adjacent to the existing outfall gates within New Territory; this required the acquisition of three residential homes for the pump station site.

Additionally, the Board approved the construction of a new 115 acre-feet stormwater detention facility. The boundaries of the new detention facility are shown in the drawing below.

This project requires the acquisition of tracts identified as 14, 21, 22, 23, 24, and the “back” portion of tract 15 as shown on the following map. Acquisition by FBCLID7 of tract 14 was completed in December 2020.

These decisions represent what the Board believes to be the most cost-efficient and fiscally responsible projects available to comply with the new drainage criteria and protect the residents and businesses within the District from future flood events.
