Houston Community College Campus Expansion

EHRA was selected as one of two firms to provide professional surveying services under contract to Houston Community College System.

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.

Towne Lake

EHRA was selected by the client to provide engineering design and to serve as District Engineer for the 2,400 acre Towne Lake Development. Our survey department retraced the overall boundary and performed a topographic survey of the site.

Harris County MUD 500 Horsepen Creek Regional Lift Station

EHRA designed an expansion that implemented the installation of a new triplex lift station operating in conjunction with the existing duplex lift station.

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.
