Facilities requiring expansion were also common wall construction, and the EHRA team converted the facilities into aerobic digesters and sludge thickeners.
Project totaled 640 acres including 1256 Residential Lots. EHRA designed, created construction plans, publicly bid and preformed Construction management.
This project was the second phase of parks implementation outlined in the District's Parks Master Plan, which was completed by EHRA in 2007. Utilizing the site of a recently demolished former wastewater treatment plant provided an opportunity to create a passive park space for District residents.
In 2006, Caldwell Companies sought to create Towne Lake as a community where residents and services could be connected by water. Their vision included boat docks and marinas augmenting traditional walking trails to navigate a vibrant residential community. EHRA was the perfect partner to take Caldwell Companies’ vision and create this livable suburban oasis.
Engineering design and construction phase services of water, sewer, drainage and paving for four subdivision sections and off-site channel (123 acres out of a 400 acre subdivision). There was 60-feet of elevation difference on this site and wooded lots were left in their natural state which required the installation of retaining walls.
EHRA Engineering is proud to have partnered with the City of Sugar Land (COSL) to enhance the City's shared-use path (SUP) trail system, creating safer and more accessible pedestrian connections for the community. This project was an exciting opportunity for the team, contributing to the City's long-term vision for pedestrian-friendly spaces.
EHRA was contracted by the City for the design and implementation of four pedestrian bridges strategically placed to connect different sections of the trail system. These included three single-span bridges (90 feet, 100 feet and 150 feet) and one two-span bridge (130 feet and 100 feet) that cross the City's drainage channels. Each bridge was carefully designed to blend with the surrounding environment while providing a durable and safe passage for pedestrians.
A significant focus for this project was safe connectivity. One of the project's standout features is the innovative undercrossing integrated beneath an existing roadway. This addition allows pedestrians to continue along the trail system without having to navigate traffic, significantly improving safety and accessibility. To ensure a secure and user-friendly experience, the undercrossing was designed with retaining walls and strategic lighting and handrails to enhance visibility and usability.
Beyond bridge construction, EHRA also collaborated with COSL to seamlessly link various sections of the paved sidewalk network along drainage channels and roadways. These connections strengthen the continuity of the pedestrian infrastructure, making it easier for residents to navigate their community safely and efficiently.
This project mirrors EHRA’s mission in delivering high-quality, community-focused engineering solutions. Prioritizing safety, accessibility and sustainability, we are proud to have played a role in shaping Sugar Land’s growing trail system, fostering a more walkable and connected city for residents and visitors alike.
