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.
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.
The facility features an activated sludge process system. Additionally, the facility is equipped with an emergency standby diesel generator.
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.
On Saturday, July 23rd, EHRA took part in the groundbreaking for a new park inside the Katy neighborhood of Lakeview, to be named Callegari Park, after former Texas State Representative William Anthony Callegari, Sr., known as Bill Callegari.
The event was hosted by Harris County M.U.D. 64. The new multi-use park will be approximately 3.5 acres and will boast multiple playgrounds, an educational butterfly garden, a pavilion, multiple fitness stations and .35 miles of concrete trail. The park will be accessible by a 17-space parking lot adjacent to Repiton Way.
EHRA is the district engineer for Harris County M.U.D. 64 and completed the site civil engineering for this project. In addition, EHRA worked with landscape architect Murr Incorporated Landscape Consultants on the new park. EHRA Senior Principal Jim Russ is also a long-time friend and colleague of Bill Callegari.
"I am incredibly flattered yet humble and appreciative that Harris County M.U.D. 64 felt my contributions were deserving of such an accolade,” commented Callegari, who was delighted to learn that EHRA, Jim Russ and Michael Murr were directly involved in the project. “Knowing these two companies and individuals are involved, I know this park will be one the community will be able to enjoy for years to come," he added.
Representative Bill Callegari represented the Katy area since his election to the Texas State House of Representatives in 2000. Mr. Callegari has passed several bills to eliminate unnecessary government functions, lower citizens’ tax burdens, and improve accountability until his retirement from office in 2014. Representative Callegari has worked on many water policies, eminent domain, transportation, low income housing reform, and government streamlining during his tenure in the House.
A Licensed Professional Engineer for over four decades, Callegari holds a Bachelor’s Degree in Agricultural Engineering from Louisiana State University and a Master’s Degree in Civil Engineering from the University of Houston. Callegari and his wife, Ann, have been happily married for more than 50 years and have four children and eleven grandchildren. He retired in January of 2015 and now enjoys life with his wife in the Katy area.
