Project Cost: $19.2 Million

Location: Little Elm, Texas

Hillwood Communities contracted Jones|Carter to provide design and engineering services for Phase I of the Union Park community. Union Park is a 1,100-acre master-planned community in Little Elm, Texas. The community has 3,200 planned homes and a 35-acre park with open greenbelts and natural ponds. Union Park also provides an amenity center, open air pavilion, resort-style pool, sports fields, pockets parks, and trails.

J|C provided design for water, wastewater, drainage, and paving infrastructure for residential lots and the excavation of 300,000 cubic yards of soil for a detention pond, a community park, and roadways. Due to the size and scope of Phase I of Union Park, open and continual communication with all parties was necessary to ensure success. Weekly meetings were held with the client, community stakeholders, and the various public entities throughout the entirety of construction of the project. This helped keep the project on schedule, allowed for proactive problem-solving at all levels, and facilitated solutions that could be put in place without impacting the budget or the schedule.

J|C’s extensive coordination with TxDOT, Upper Trinity Regional Water District (UTRWD), Mustang Special Utility District, and the town of Little Elm kept all entities on the same page and Union Park moving forward. The J|C team resolved issues regarding a lack of documentation of the existing infrastructure, and the approval and permitting of the new construction and design of a roundabout.

The J|C team worked closely with TxDOT to facilitate approval and permitting for the construction of two deceleration lanes and a 48-inch reinforced concrete pipe bore across US Highway 380. To resolve the lack of construction documentation and plans detailing existing utilities and infrastructure, J|C worked alongside UTRWD to construct the new storm infrastructure in a manner that would serve the project, but also keep infrastructure in place. Additionally, a sanitary sewer trunk main was designed to connect to the existing sanitary sewer system at the UTRWD Riverbend Wastewater Treatment Plant. As the town of Little Elm had no definitive design criteria in place for creating a roundabout, the J|C team followed Federal Highway Administration standards on the design, working alongside Little Elm’s traffic engineer.

Phase I was completed in August 2015.
