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 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.
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.
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.
In 1936, soon after the reelection of President Roosevelt, my Great Grandfather, Truman Edminster, Sr., opened the doors of Edminster Engineering. He had no way of knowing that the legacy he began would become the EHRA we know today. One that would carry on long after him and for the next three generations of his family.
Since that November day in 1936, as any long-standing institution does, Edminster Engineering has seen ups and downs, good times and challenging times. We have had the great fortune to be involved with countless projects that have helped shape the Greater Houston region into the booming metropolis it is today. We have been blessed to have the opportunity to work with some of the most respected and talented ‘greats’ in our industry whom with we have weathered the ups and downs together for nearly nine decades.
We begin a year-long celebration to the continuing heritage begun by my Great Grandfather and carried forward by Truman Edminster, Jr. (my uncle), Terry Russ, Jr. (my father) and Truman Edminster, III (who still serves the firm today). We have gained momentum into the 21st Century which will propel EHRA for decades to come. Some may wonder what is our ‘secret sauce’; it is our legacy of service.
EHRA has always been focused on the experience and satisfaction of our clients and our team members. As we continue to grow and mature as a firm, and prepare to seamlessly pass the baton to the next generation, our top priority will not change. We have built a culture around taking care of people. It is who we are, and it is what we do.
It is our ultimate hope, wish and desire to continue the EHRA legacy for the next 85 years and beyond. We are confident that together the team will achieve that goal.
Here’s to a great New Year. Blessings to all, and to your families, in 2021!
