The new roadway design comprises of one-half major thoroughfare, conventional drainage, a 600-ft long bridge over Willow Fork Bayou, Retaining walls and intersection improvements at FM 1463 (including traffic signals and illumination).
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.
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.
This project was the second phase of parks implementation outlined in the District's Parks Master Plan, which was completed by EHRA in 2007. Utilizing the site of a recently demolished former wastewater treatment plant provided an opportunity to create a passive park space for District residents.
In the realm of district engineering, seamless maintenance and management of all essential services is the District Engineer’s primary objective and responsibility. With aging infrastructure requiring consistent attention, the district summons resources, primarily through bonds, to finance critical improvements and repairs. One of the most interesting services that EHRA Engineering’s District Services practice area offers is the research and coordination with multiple consultants in preparation for bond elections. Most recently, EHRA assisted Harris County Municipal Utility District No. 43 in passing a $48 million bond election in May of 2023.
Authorization of funds for bonds is meticulously planned for during District creation. As the District nears its limit of authorized bonds, EHRA analyzes the current and future infrastructure needs. We look at the aging sanitary sewer and water line facilities, possible annexations, district population growth and more. As District Engineer, EHRA gathers all necessary data to prepare a Summary of Costs for the District and forecasts their needs for the next 20 to 30 years. In coordination with the attorney and the financial advisor to the District, the Summary of Costs accounts for the rehabilitation projects, inflation and interest rates. After careful review from District consultants, the Summary of Costs is presented to the board for approval.
Community engagement proves paramount during bond elections. Public town hall meetings serve as a platform for addressing questions and showcasing detailed maps highlighting the imperative need for rehabilitating sanitary sewer structures, waterlines and drainage systems. The breakdown of costs over the projected 30-year period presents a deeper understanding among the constituents, resulting in a more informed voting process.
The successful HCMUD 43 bond election is a testament to the collective effort in maintaining sustainable growth within the community. It not only substantiates the detailed planning exercised by EHRA but also the unwavering commitment to public welfare. That being said, the process of creating a bond for the districts is not without challenges. Forecasting future requirements and the evolving community needs presents a significant hurdle. Communicating the nature of bond elections to the public and clarifying misconceptions about potential tax implications requires a delicate balance of transparency and expertise. Although challenging, the most rewarding part in working on these types of services is the unique role that we play in serving our community.
HCMUD 43 marks one of dozens of bonds EHRA has been institutionally involved in for MUD districts in the Greater Houston region. As EHRA continues its efforts in supporting community growth and resilience, the positive impact of our collaborative endeavors with the districts and their communities extends well beyond the scope of infrastructure development.
