The sheer size and scope of a project as large and complex as phase one of Union Park in Little Elm, Texas, brings inherent challenges. Jones|Carter is very experienced at navigating the anticipated issues that tend to arise on such a project, and is particularly adept at successfully addressing unexpected challenges, as well. On this project we resolved issues with lack of documentation of existing infrastructure, and approval and permitting of new construction and design of a roundabout.


As with all of our projects, one of Jones|Carter’s primary tools is open and continual communication with all parties. For Union Park, weekly meetings throughout the entirety of construction of the project with the client, community stakeholders, and the various public entities kept 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. JC’s extensive coordination with TxDOT, Upper Trinity Regional Water District (UTRWD), Mustang Special Utility District (Mustang), and the town of Little Elm kept all entities on the same page and Union Park moving forward.

We worked closely with TxDOT to facilitate approval and permitting for the construction of two deceleration lanes and a 48” reinforced concrete pipe bore across US-Highway 380. To resolve the lack of construction documentation and plans detailing existing utilities and infrastructure, JC worked hand-in-hand with 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, we followed Federal Highway Administration standards on the design, working with Little Elm’s traffic engineer.

Union Park is a 1,085-acre master planned community featuring a 35-acre park with open greenbelts and natural ponds. Future home to 3,200 single-family homes, the community boasts an amenity center, open air pavilion, resort-style pool, sports fields, pockets parks, and trails. Jones|Carter 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. Phase I was completed in August 2015.
