A drainage study was conducted in 2022 to assess the detention requirements for approximately 207 acres of undeveloped Sugar Land Business Park land. The study indicated a need for 60 acre-feet of regional detention to accommodate full development and prevent downstream flooding, erosion, and property damage.

This project will contribute 13 acre-feet to the required volume, while the remaining 47 acre-feet will be addressed in the future during Phase II and III. Following the study's recommendation, the plan involves deepening the existing detention pond's 3.8-acre eastern section in the northeast corner of the Business Park. This enhancement will provide an additional 13.0 acre-feet of detention capacity. The depth of this section of the pond will be increased by approximately 3 feet to match the flowline elevation of the rest of the pond.

The scope of work for the CIP CDR2302 project includes

• soil excavation and haul-off,
• removal and replacement of pilot channels, and
• concrete slope paving within the existing Sugar Land Business Park Northeast Detention Basin.
