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.
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 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 designed an expansion that implemented the installation of a new triplex lift station operating in conjunction with the existing duplex lift station.
EHRA completed preliminary engineering, phase one environmental site assessment and schematic development for the widening of Northpark Dr. between US 59 and Woodland Hills Dr. EHRA also provided program management, drainage analysis and design, traffic engineering, environmental documentation and schematic design for the roadway, as well as grade separation at the Loop 494/UPRR railroad crossing.
EHRA conducted traffic operations and access management studies for the Northpark Dr. corridor. This corridor is approximately 2.2 miles long and has major signalized and unsignalized intersections and driveways that access various subdivisions and industrial developments. These studies laid the groundwork for the widening of Northpark Dr. from a four-lane boulevard cross-section to a six-lane boulevard complete street. The new street design includes low impact development drainage, conventional drainage, a grade separation at the UPRR crossing with mechanically stabilized earth retaining walls, two at-grade crossings for bi-directional frontage access, reconstruction of two concrete bridges over a diversion channel, intersection improvements, a roadway-adjacent multiuse path and traffic signal improvements.
Drainage analysis and design included hydrologic and hydraulic studies of both existing and proposed conditions to demonstrate that proposed project components would not adversely affect the 100-year floodplain in the area. The roadway and traffic designs contained horizontal and vertical alignments, cross-sections, plan and profile, sidewalk and bicycle accommodations, intersection layouts, traffic control plans and signing and pavement markings.
As the program management firm, EHRA coordinated with TxDOT, UPRR, the City of Houston Council District E, COH Planning and Development Department, COH Public Works and Engineering Department, Montgomery County, Harris County, HCFCD and area residents throughout the project.
The Structures team serves as a dynamic microcosm for the diverse engineering capabilities at EHRA Engineering. Operating within a fast-paced environment, the department manages a continuously revolving portfolio of structural projects, including vehicular and pedestrian bridges, water and wastewater treatment facilities, lift stations, junction boxes, retaining walls, weirs and specialized monuments. Executing these complex designs demands significant technical expertise, driving daily collaboration between our internal structural team, other specialized departments at EHRA Engineering and various external consultants and contractors.
Collaboration Within Services
The Structures team partners extensively with our Water & Wastewater Management team to deliver robust structural drawings, calculations and analytical modeling. Utilizing Autodesk Revit for advanced BIM modeling ensures that structural sheets and spatial modifications are updated efficiently alongside dynamic design changes. This integrated workflow supports vital regional infrastructure, including the Harris County MUD 578 WTP Phase 2, WCMUD 46 Lift Station and active design coordination on the WHC MUD 21 WWTP expansion.
Collaborative efforts with our Land Services team include the ongoing construction of Karsten Blvd Bridge, which features a complex 37-degree skew designed to align precisely with the roadway geometry and underlying river flow. Structural design and construction progress continue for Preservation Creek MUD 1 Phase 1 Pinnacle Parkway crossings, Grace Landing Bridge, Bluebonnet Detention Junction Box and Chambers Lake Spillway Weir.
Partnering with the Landscape Architecture team, the department provides structural engineering for public hardscapes, amenities and pedestrian access. Current projects feature a pedestrian bridge in Firethorne West alongside detailed structural details for entrance monuments and amenities across major land developments, including Mirabella, Brazos Bend, Katy Grand Village and Northpark Enclave.
The department frequently addresses public infrastructure updates for District Services, recently completing bulkhead rehabilitation designs at Willowcreek Ranch and initiating the structural design of a pedestrian bridge tied to a drainage redirection project. Additional district support includes structural drawings for the NGCMUD 1 Spillway Channel rehabilitation.
Over the past year, the Structures team has prioritized refining its Autodesk Revit BIM workflow. Developing cross-platform interoperable models has proven essential for the modern construction phase, allowing complex structural details to translate seamlessly from initial schematics to field applications. The team remains dedicated to engineering precision and welcomes all inquiries regarding structural design, calculations and peer plan reviews.
Structures In Everything
When most people think of Structures, bridges or other prominent infrastructure often comes to mind. While those types of projects are a big part of what we do, structural engineering is also embedded in countless facilities and spaces that people rely on every day and may not even realize. As highlighted previously, we work closely with the other services provided here at EHRA Engineering to provide the best work we possibly can and hold true to our One Team value and philosophy. Whether you’re looking at your local park, driving through your favorite master planned community or simply noticing the infrastructure that keeps your community running, remember that behind all of it is a team of disciplines working together. At EHRA, Structures is one piece of that collaboration and an essential part of building the communities we serve.
