Project totaled 640 acres including 1256 Residential Lots. EHRA designed, created construction plans, publicly bid and preformed Construction management.
Facilities requiring expansion were also common wall construction, and the EHRA team converted the facilities into aerobic digesters and sludge thickeners.
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.
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.
EHRA offered its Landscape Architectural services to complete a Parks and Trails Master Plan for the District.
The Houston Ship Channel is a busy place, and widening the Sam Houston Tollway will require new twin bridges across the Houston Ship Channel.The main span of each of the cable-stayed bridges will be 1,320 ft, and they will provide four toll lanes and full shoulders in both directions. One of the largest challenges is the coordination of the construction processes amid 120 major utility pipelines and bustling UPRR and PTRA rail lines at one of the country’s busiest seaports, says Mike Perez, Harris County Toll Road Authority senior staff engineer. Another challenge is poor soils at the site, which will require the drill shafts for pylons to be more than 200 ft deep, he says.
