EHRA performed preliminary drainage area delineations for nine creek crossings and calculated approximate 100-year flows for each culvert crossing. Culvert structures were sized for each of the six crossings, ranging from 48” round pipe culverts up to dual 5’x5’ box culverts.
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.
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.
EHRA offered its Landscape Architectural services to complete a Parks and Trails Master Plan for the District.
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.
If you've ever traveled Texas, you've seen some pretty amazing briges, and a few that just look like art. A few from the Houston area have made an impressive list of Beautiful Texas Bridges. Rainbow Bridge, Bridge City: The first time I saw this thing I was terrified driving from Houston. As Texans, especially around here, we see nothing but flat land, but somehow in the distance I saw car lights way up in the sky and wondered what in the world was happening. Why is the Rainbow Bridge so high? (It's the tallest in Texas.) The city of Beaumont thought it would interfere with shipping, so the builders had to agree to make it high enough to accommodate a U.S. Navy ship that dirigibles hooked up to, which was the tallest ship in the fleet at the time. Fred Hartman Bridge, Baytown and La Porte: This bridge is famous for its sail motif. Ridden by more than a few cyclists, it's a popular one on the way to many beach spots close to Houston. Martin Luther King Bridge, Port Arthur: Old Texans still refer to this by its original Gulfgate Bridge name. Also impressive, it warrants a visit as well.
