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 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.
EHRA was selected by the client to provide engineering design and to serve as District Engineer for the 2,400 acre Towne Lake Development. Our survey department retraced the overall boundary and performed a topographic survey of the site.
Project totaled 640 acres including 1256 Residential Lots. EHRA designed, created construction plans, publicly bid and preformed Construction management.
EHRA has been providing Professional Survey Services to Houston Community College System since 2013. Since then, EHRA has filled 26 work orders across eight campuses. This successful partnership has recently been rewarded with a new contract, awarded in 2019 for Professional Survey Services for an innovative new education facility located at the HCCS Northeast Campus.
The new facility, named the HCC Regional Emergency Response Training Center, was detailed at the 2020 State of the College event. Dr. Cesar Maldonado, Chancellor of the six-college system, addressed the attendees on a new, innovative facility to provide training to local first responders in high water rescues. Hurricane Harvey had brought to light the need of focused and thorough training in these techniques and HCCS has responded.
Weeks after the State of the Campus event, EHRA received the proposal request to provide Land Title and Topographic Survey for the new facility. The scope of the survey is 70 acres of the existing Northeast Campus to establish boundary lines for five reserves and three roads. It also includes a 35-acre Topographic Survey including location of on-site utilities.
“This is a groundbreaking project for our region.” Bob Boelsche, RPLS, EHRA’s Survey Project Manager said. “This new facility will actively positively impact the lives of other Texans and we are thrilled to be a part of it.”
The final survey included the boundary and topographic survey information, contour lines, 3-D surface model and full delineation of the current flood plain affecting the campus. The final survey was delivered in both signed and sealed survey format and digital format in AutoCad in May 2020.
HCC Regional Emergency Response Training Center is currently under construction and will in upcoming years as an innovate education resource in Southeast Texas.
