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.
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 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.
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.
The purpose of this project was to convert the existing at-grade crossing of Brazoria County Road 56 (CR 56) and State Highway 288 (SH 288) into a diamond interchange that includes a new overpass bridge and providing access to the newly developed Meridiana Development. Coordination with TXDOT, area landowners, utility companies, and Brazoria County was integral in obtaining approval and acceptance of the project. The main design challenge for this project was to accommodate double intersections on the west side of SH 288 to tie into existing access roads with two-way traffic and a new southbound on-ramp within a close proximity. EHRA coordinated with TxDOT throughout the project from preliminary concepts for the intersection and bridge through final design and construction. Each component of this project was designed in accordance with TxDOT standards and criteria.
EHRA Engineering has been at the forefront of the surveying industry since its inception in 1936. With a focus on diverse projects ranging from public sector initiatives to single-family developments, EHRA has consistently delivered high-quality surveying services to its clients. One of EHRA’s Surveying and Mapping team's most recent projects involved collaborating with Trammell Crow (TCC), a global commercial real estate developer with an impressive portfolio of nearly 2,900 acquired buildings valued at $75 billion.
Through this partnership, EHRA's Surveying and Mapping team lent their expertise to TCC ambitious project—the development of Weiser Business Park. Formerly known as Weiser Air Park, this 102-acre airport in northwest Harris County operated from 1951 to 2019 until it was acquired by TCC. The completed project will have over 1.5 million square feet of space within five proposed industrial warehouses. EHRA played a pivotal role in the transformation, providing comprehensive Land Title Survey services for the site acquisition, which included an additional 30 acres along the south boundary, expanding the development to a total of 132 acres.
EHRA's involvement extended to performing a Topographic survey to locate any surface features and elevations using innovative techniques such as drone-based LiDAR and conventional surveying methods. This survey was crucial for engineering design. Part of EHRA’s scope also included platting the expansive 132 acres into seven separate reserves, along with the dedication of Fallbrook Drive, a key feature bisecting the development. Furthermore, EHRA's survey team prepared multiple boundary and as-built surveys essential for title transfers and construction compliance within the development.
Weiser Business Park will be a signature industrial development in the region, and EHRA takes pride in the integral role they provided along the way. This collaborative effort exemplifies the successful synergy between a seasoned engineering firm and a global real estate powerhouse and will soon result in the creation of a landmark project, contributing significantly to the economic landscape.
