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 designed an expansion that implemented the installation of a new triplex lift station operating in conjunction with the existing duplex lift station.
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.
Facilities requiring expansion were also common wall construction, and the EHRA team converted the facilities into aerobic digesters and sludge thickeners.
In 2006, Caldwell Companies sought to create Towne Lake as a community where residents and services could be connected by water. Their vision included boat docks and marinas augmenting traditional walking trails to navigate a vibrant residential community. EHRA was the perfect partner to take Caldwell Companies’ vision and create this livable suburban oasis.
If you've ever traveled Texas, you've seen some pretty amazing briges, and a few that just look like art. A few from the Houston area have made an impressive list of Beautiful Texas Bridges. Rainbow Bridge, Bridge City: The first time I saw this thing I was terrified driving from Houston. As Texans, especially around here, we see nothing but flat land, but somehow in the distance I saw car lights way up in the sky and wondered what in the world was happening. Why is the Rainbow Bridge so high? (It's the tallest in Texas.) The city of Beaumont thought it would interfere with shipping, so the builders had to agree to make it high enough to accommodate a U.S. Navy ship that dirigibles hooked up to, which was the tallest ship in the fleet at the time. Fred Hartman Bridge, Baytown and La Porte: This bridge is famous for its sail motif. Ridden by more than a few cyclists, it's a popular one on the way to many beach spots close to Houston. Martin Luther King Bridge, Port Arthur: Old Texans still refer to this by its original Gulfgate Bridge name. Also impressive, it warrants a visit as well.
