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.
EHRA assisted with the district creation of Montgomery County Municipal Utility District No. 126 to accommodate a ±329 acre master planned community located in northern Montgomery County in the City of Conroe, south of League Line Road, west of Longmire Road, and adjacent to Lake Conroe.
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).
EHRA designed an expansion that implemented the installation of a new triplex lift station operating in conjunction with the existing duplex lift station.
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 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.
