West Road Phase 2 Sidewalk

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.

Greens Bayou Trail Phase 1

Identified as a top priority during the development of the District’s Parks Master Plan, this portion of trail was the first phase of over two miles of planned trails to provide connectivity and recreation for District residents.

Jacobs Reserve Development

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.

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.

Meridiana-Oasis Village
project overview

The master planned community in Brazoria County

Meridiana is an upscale master planned community in Brazoria County comprised of over 80 sections. The project consisted of surveying and engineering design for excavation, paving and grading, water mains, storm sewers, sanitary sewers, detention basins and amenity features and street paving for a 2,600 acre development which includes 5,500 single-family residential lots, multi-family residential, commercial, school, and park development.

The project 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. The project also includes a design of several bridges including a crossing over the Burlington Northern Santa Fe Railroad and multiple crossings over drainage facilities. The project also required design and construction of two wastewater treatment plant facilities and two water plants capable of serving the development’s needs.

Project Overview

A Modern Traffic Solution

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.

Project Approach

Coordinating Multiple Phases

EHRA designed a 640-foot long bridge to span SH 288 in accordance with TxDOT green ribbon standards. The purpose of the bridge was to facilitate traffic movement along CR 56 and across SH 288. In addition to the bridge, EHRA designed and prepared construction drawings for the 2-lane frontage roads and intersection design for the project. Roadway drainage was analyzed for the project through hydrologic and hydraulic analysis, which resulted in the design of 2 detention basins required to mitigate the increased runoff from the project. Also as part of the project, EHRA designed and prepared construction sequencing/ traffic control plans and details that included construction phasing, location of construction signs, barricades, drums, and speed limits, and development of a detour plan for each construction phase. Illumination design was also a part of the project with a focus on safety lighting at merge and diverge areas. Design included foundations, light poles and their spacing, mounting heights, voltage drop calculations, an electrical wiring diagram, electric service coordination and conduit runs.

Project Outcome

Best Community and Best Developer

Meridiana was voted Best Community and Best Developer of the Year from the Texas Association of Builders and the PRISM Awards. Residents can find anything here: a morning workout, an evening concert with friends, a weekend by the pool with the kids, a cappuccino and a healthy snack. All of this contributed to Meridiana being awarded Houston’s Best Amenitie. Oasis Village is like no other amenity package you’ve seen before.
