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.
On-going surveying for property acquisition and engineering design surveys of re-routing of Buffalo Bayou north of downtown Houston between North Main Street and McKee Street. Services to be provided include “soundings” for Buffalo and White Oak Bayous.
EHRA assisted with the district creation of Montgomery County Municipal Utility District No. 126 to accommodate a ±329 acre master planned community located in northern Montgomery County in the City of Conroe, south of League Line Road, west of Longmire Road, and adjacent to Lake Conroe.
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.
Identified as a top priority during the development of the District’s Parks Master Plan, this portion of trail was the first phase of over two miles of planned trails to provide connectivity and recreation for District residents.
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.
