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.
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.
A 720-acre gated master planned community located off Telge Road, just north of Willow Creek. See how EHRA was involved in this project.
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.
The Governor has declared May 18 – 22, 2020 as "Texas Flood Awareness Week." Texas Flood Awareness Week (TxFAW) brings awareness to the citizens of Texas of the dangers that flooding can present. Flash flooding is the number one weather-related killer in Texas with more than 50% of all flash flood fatalities nationwide involving vehicles. Flooding in Texas is a consistent threat to people and properties. Flash floods are often unpredictable, the public should recognize flood hazards in areas they frequently visit.
At EHRA Engineering, the Hydrology & Hydraulics (H&H) Team uses historical data from the Harris County Flood Warning System to create models that simulate the resulting water levels for our clients. From this information, our clients can take the necessary steps to plan flood mitigation strategies such as detention basins, bypass channels, or channel improvements to help alleviate flooding issues. The Harris County Flood Warning System measures rainfall amounts and monitors water levels on a real-time basis throughout Harris County and into some of the surrounding counties.
Flood mitigation is a central issue for the Gulf Coast region. EHRA Engineering has a remarkable team with expertise in performing hydrologic and hydraulic analyses for a variety of projects. Hydraulics & Hydrology services provided by EHRA Engineering include: 2D analysis, flood plain mapping, bridge and culvert hydraulics, riverine hydraulics, scour analysis, regional and local storm water impact and mitigation analysis, urban storm water management and master planning.
What is a flash flood? Take action! A Flash Flood is flooding that occurs when it rains rapidly on saturated soil or dry soil that has poor absorption ability. These conditions worsen considerably in periods of drought. It may be caused by heavy rain associated with a severe thunderstorm, hurricane, or tropical storm. Flash flooding occurs quickly and catches most people off guard.
What is a flood watch? Be prepared! A Flood Watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.
What is a flood warning? Take action! A Flood Warning is issued when the hazardous weather is imminent or already happening.
