Harris County MUD No. 536 Wastewater Treatment Plant & On-Site Lift Station Expansion

The facility features an activated sludge process system. Additionally, the facility is equipped with an emergency standby diesel generator.

Northpark Drive Mobility Project

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.

288 & CR56

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. Coordination with TXDOT, area landowners, utility companies, and Brazoria County was integral in obtaining approval and acceptance of the project.

Cane Island Parkway

The new roadway design comprises of one-half major thoroughfare, conventional drainage, a 600-ft long bridge over Willow Fork Bayou, Retaining walls and intersection improvements at FM 1463 (including traffic signals and illumination).

MUD 188

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.

Meridiana Master Planned Community

Jared Bowlin PE Senior Vice President Treasurer Practice Area Leader

Meridiana is an upscale master planned community in Brazoria County comprised of over 3,000 acres. The socially active community is designed to highlight the natural landscape of the area, and includes incredible landscaping, elegantly maintained creeks, bayous and parks connected by bridges and miles of winding pathways, developed to encourage residents to explore the outdoors.

“EHRA Engineering is excited to be a part of this project,” said Jared Bowlin, Senior Vice President and Practice Area Leader of Land Services for EHRA. “We were involved in providing a unique blend of vision and creativity to Meridiana, a community that values active lifestyles and education, with learning opportunities throughout the community.”

The Texas Association of Builders awarded Meridiana Best Community of the Year at the 2017 Star Awards. The development was also awarded the Best Community of the Year in the PRISM Awards, sponsored by the Greater Houston Builders Association.

EHRA provided land planning, surveying, and engineering design for excavation, paving and grading, water mains, storm sewers, sanitary sewers, detention basins and amenity features and street paving for this 3,200-acre development which includes 5,500 single-family residential lots, commercial, schools and park development.

The master planned community includes remapping the Chocolate Bayou watershed to remove large portions of the development from the 100-year flood plain and the design of a complex drainage system consisting of multiple detention facilities to be utilized as amenity features. EHRA was also responsible for the design of several bridges including a crossing both over the Burlington Northern Santa Fe Railroad and under CenterPoint Energy transmission lines, as well as multiple crossings over drainage facilities. The project required design and construction of two wastewater treatment plant facilities and two water plants capable of serving the development’s need.
