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 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 was selected as one of two firms to provide professional surveying services under contract to Houston Community College System.
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 worked with the District to create a comprehensive Parks Master Plan, which included recommendations for the development of over two miles of hike/bike trails adjacent to local streets, and within flood control and utility pipeline easements. The District began implementation of the Plan by prioritizing the beautification of West Road, a major arterial street that runs through the District.
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.
