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.
The facility features an activated sludge process system. Additionally, the facility is equipped with an emergency standby diesel generator.
EHRA completed a site-specific planning and visioning study for the proposed 470-acre San Jacinto Boulevard District (SJBD) in Baytown, Texas.
EHRA planners, hydrologists and landscape architects worked together to propose an alternative use for the space, re-developing the basin into an amenity pond. EHRA carefully selected native plant materials for both their ability to survive in the harsh conditions of the basin as well as providing filtration for improved storm water quality.
EHRA performed preliminary drainage area delineations for nine creek crossings and calculated approximate 100-year flows for each culvert crossing. Culvert structures were sized for each of the six crossings, ranging from 48” round pipe culverts up to dual 5’x5’ box culverts.
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.
