NTMWD Muddy Creek Administration Building Improvement and Expansion in Wylie, TX

The North Texas Municipal Water District completed a $973,558 expansion of its Muddy Creek Operations Building at 5400 Pleasant Valley Road in Wylie. This project, filed as the NTMWD Muddy Creek Administration Building Improvement and Expansion, added 3,968 square feet of new space to the existing facility. The construction concluded with a final inspection passed in January 2026, and the Texas Department of Licensing and Regulation closed the project file in September 2026.

The scope of work focused on improving the existing operations facility by adding locker rooms, a break room, and updated utilities. A new breezeway connects the original structure to the expansion, creating a continuous workflow for staff. The project was privately funded on private land for private use, reflecting the district’s internal infrastructure needs rather than a public-facing retail or commercial development.

Project Specifications and Cost

With an estimated cost of $973,558 for 3,968 square feet, the project averaged $245 per square foot. This figure is above the county median of $173 per square foot for similar additions to existing buildings in Taylor County. The scheduled build window was 1,369 days, which is longer than the county median of 214 days for this type of construction. The extended timeline likely reflects the complexity of integrating new utilities and structural connections into an active water district facility.

Huitt-Zollars, Inc. served as the design firm of record for the project. The firm has registered six other projects with TDLR, totaling $11,505,566, including work in Fort Worth, Houston, Weslaco, Anna, and El Paso. The North Texas Municipal Water District, the owner of record, has six other TDLR-registered projects totaling $41,312,878, including the Wylie Service Center and the Shiloh Pump Station in Richardson.

The project was registered with TDLR in July 2020, and plan review was completed the same month. Construction began in October 2020. The final inspection passed in January 2026, marking the completion of the physical construction phase. The TDLR status is now Project Closed, indicating that all regulatory requirements for the accessibility review process have been satisfied.
