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 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 conducted a traffic engineering study to identify the impacts of a proposed master development located near the intersection of FM 1488 and Peoples Road in the City of Conroe.
EHRA designed an expansion that implemented the installation of a new triplex lift station operating in conjunction with the existing duplex lift station.
This project was the second phase of parks implementation outlined in the District's Parks Master Plan, which was completed by EHRA in 2007. Utilizing the site of a recently demolished former wastewater treatment plant provided an opportunity to create a passive park space for District residents.
Cane Island is an upscale master planned community located on the west side of the City of Katy in Waller County. The 1,009-acre development is comprised of 45 sections, including dedicated areas for approximately 2,100 single-family residential homes, a new elementary school in Katy ISD, and a community park. The Cane Island project started in 2010 and is projected to see complete home build-out within the next three years. EHRA is contracted to provide surveying and engineering design for excavation, paving and grading, water mains, storm sewers, sanitary sewers, detention basins, and other amenities.
An important objective for the Cane Island master planned community was to remove portions of the area that fall in the 100-year floodplain. The overall project includes the design of 4 complex drainage systems with 25 detention ponds, also serving as amenity features, that outfall into Cane Island Branch and Snake Creek. Some of the more attractive features of the development are abundance of beautiful landscaping and planting features, the major connectivity provided by the many walking trails and the Amenity Center that includes a restaurant and recreation center on the community property. “One of the most challenging aspects of this project was working around the various pipelines, easements and electric transmission towers across the project site. It required a great coordination effort with both private and public entities, and we had to implement creative design solutions to make this land developable,” said Project Manager, Thomas Arnold.
Improvements to US Highway 90 and Cane Island Parkway down to Interstate 10 were designed and constructed for the projected traffic increases with growth of the development. Water supply and wastewater treatment for this project is provided by the City of Katy.
