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.
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 completed a site-specific planning and visioning study for the proposed 470-acre San Jacinto Boulevard District (SJBD) in Baytown, Texas.
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 designed an expansion that implemented the installation of a new triplex lift station operating in conjunction with the existing duplex lift station.
The primary objective of the Walker Street Rehabilitation project is to generate solutions that safely accommodate and connect all traffic modes for this important thoroughfare in the heart of TIRZ 15 (located in East Downtown Houston). The EHRA team, led by Project Manager Kyle Macy, PE, reimagined the roadway functions by rearranging unsafe bike lanes, redesigning bike crossings at major intersections, and reconnecting bike networks. This reimagination integrated future considerations for the North Houston Highway Improvement Project (NHHIP). The NHHIP is a planned reconstruction of Interstate Highway 45 North, between Houston's downtown and the North Sam Houston Tollway (also known as Beltway 8) that includes segments of connecting freeways.
Macy, along with EHRA engineers Ashley Sowards, PE, Diego Gil, E.I.T., ENV SP, and Jessica Jia, PE, PTOE, RSP1, ENV SP, developed various alternatives to best fit safe bike lanes within existing pavement limits. In order to combat the limited pavement width of Walker Street, the team positioned bike lanes behind modified handicap-accessible parking, resulting in improved safety for both bike lane end users and individuals utilizing the modified spaces. This design option was successfully adopted by Houston Public Works and TIRZ 15.
Background
EHRA is privileged to serve TIRZ 15 for engineering services. As part of this partnership, EHRA is responsible for supporting the execution of high priority capital improvement projects. For the Walker Street Rehabilitation project, EHRA is responsible for providing design phase services and subsequently guiding the venture through both the bid and construction phases. As of May 2022, the project is currently in the final design approval phase.
Collaboration
Early in the design phase, the City of Houston (COH) informed the EHRA design team of collapsed sanitary sewer segment within the scoped limits for this project. In response to this challenge, EHRA and the COH partnered to organize and implement an interlocal agreement between the COH and TIRZ 15. This agreement states that the sewer segment repair is included in the Walker Street Rehabilitation project and the COH will be responsible for costs associated with the repair. EHRA’s efforts to establish this agreement not only protect the public dollar, but also seamlessly address a significant and necessary public works restoration.
Additionally, during the 90% review stage, the COH identified street lighting as an extra requirement for the project. As this item was not a part of the original scope or budget, EHRA promptly mobilized to incorporate a street lighting plan into the project. Working diligently with the COH, the construction project engineer was able to provide optimal pricing in an agreement that permits TIRZ 15 to expand lighting along this corridor at a minimal cost.
Safety
During project conception, the Walker Street at Emancipation Avenue intersection was identified as a safety risk for those persons utilizing the connection of the striping plan on Walker Street and the Columbia Tap Trail, a community amenity heavily trafficked by bikers and pedestrians throughout East Downtown. Due to active support and participation on the parts of the TIRZ 15 board members and administrator, along with the COH multimodal group, the intersection will now be updated with a signalized, channelized, pedestrian-activated crosswalk to protect individuals crossing this intersection.
Macy shares that the most exciting element of this project experience was successfully coordinating with TIRZ 15, private stakeholders, and the City of Houston, all with the common goal of maximizing citizen safety. In recent years, the stretch of Walker Street being rehabilitated created a major safety concern for cyclists due to hazards caused by an abandoned rail line. Multiple reports of bike riders suffering accidents after a bicycle wheel lodged in the rail line brought this issue to the forefront. To remedy this hazard, the project includes removal of the abandoned rail in conjunction with newly surfaced roadway that integrates a fresh striping plan flowing harmoniously with the overall Houston Bike Plan.
