San Jacinto Boulevard District

EHRA completed a site-specific planning and visioning study for the proposed 470-acre San Jacinto Boulevard District (SJBD) in Baytown, Texas.

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.

Northpark Drive Mobility Project

EHRA completed preliminary engineering, phase one environmental site assessment and schematic development for the widening of Northpark Dr. between US 59 and Woodland Hills Dr. EHRA also provided program management, drainage analysis and design, traffic engineering, environmental documentation and schematic design for the roadway, as well as grade separation at the Loop 494/UPRR railroad crossing.

EHRA conducted traffic operations and access management studies for the Northpark Dr. corridor. This corridor is approximately 2.2 miles long and has major signalized and unsignalized intersections and driveways that access various subdivisions and industrial developments. These studies laid the groundwork for the widening of Northpark Dr. from a four-lane boulevard cross-section to a six-lane boulevard complete street. The new street design includes low impact development drainage, conventional drainage, a grade separation at the UPRR crossing with mechanically stabilized earth retaining walls, two at-grade crossings for bi-directional frontage access, reconstruction of two concrete bridges over a diversion channel, intersection improvements, a roadway-adjacent multiuse path and traffic signal improvements.

Drainage analysis and design included hydrologic and hydraulic studies of both existing and proposed conditions to demonstrate that proposed project components would not adversely affect the 100-year floodplain in the area. The roadway and traffic designs contained horizontal and vertical alignments, cross-sections, plan and profile, sidewalk and bicycle accommodations, intersection layouts, traffic control plans and signing and pavement markings.

As the program management firm, EHRA coordinated with TxDOT, UPRR, the City of Houston Council District E, COH Planning and Development Department, COH Public Works and Engineering Department, Montgomery County, Harris County, HCFCD and area residents throughout the project.

Peoples Road

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.

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.

Texas Flood Awareness Week 2020

Admin

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.

Safety Tips:

Buy flood insurance – It’s a small price to pay for the comfort of knowing you’re covered. Flooding can occur anywhere, it depends on how fast the rain falls.
Turn around, don’t drown.®
