Location

The basin is located on an approximately 22-acre site near the intersection of Cullen Boulevard, between Dagg Road and Christia V. Adair Park.

Stage

Construction on the stormwater detention basin started in April 2020 and was substantially complete in fall 2022.

After construction is complete and final contracts are closed out, the project moves into the Operations and Maintenance stage. This becomes the responsibility of the Flood Control District’s Infrastructure Division, which will mow, repair and maintain the area.

Bond Listing

Bond Project C-05 is a “Local Only” bond project, which means there is no other funding partner at this time and total project costs would be paid with bond funding. Total funds for construction of the Stormwater Detention Basin at the Reverend William and Audrey Lawson Park (formerly known as the Dagg Stormwater Detention Basin) and Phase 3 of the South Belt Stormwater Detention Basin was $18.5 million.

Project Area Map

The University of Houston Clear Lake Environmental Institute Houston (EIH) is evaluating some innovative techniques to improve stormwater quality using floating wetlands. These techniques are being tested and are currently deployed on Potter Pond at the University of Houston Clear Lake campus. Results from the EIH study will help the Flood Control District to determine some answers to questions about deployment (installation, construction, anchors), vegetation (types, sizes, best location)and maintenance (vegetation/equipment upkeep and material types). Ideally, the Flood Control District will choose two of these island types to scale the project up and fill large surface areas (2,000 – 3,000 Sq. Ft.) at the Reverend William A. Lawson (formerly known as Dagg) Stormwater Detention Basin.

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.
