Rio Grande Valley Metropolitan Transportation Plan

Rio Grande Valley Metropolitan Transportation Plan Edinburg, Texas The Rio Grande Valley Metropolitan Planning Org (RGVMPO) selected DCCM to assist in the development of their 5-year update to the Metropolitan Transportation Plan (MTP) originally adopted in 2020. This 2050 MTP Update is the first full MTP update for the new RGVMPO, which was formed in 2019. DCCM assistance to the RGVMPO allowed them to adopt the 2050 plan in December 2025 and obtain favorable ratings for the plan from FHWA Texas. The 2050 MTP includes the MPO’s robust evaluation of potential project funding and financial capacities at the local level as a complement to DCCM’s evaluation of federal funding trends and forecasts. The 2050 MTP included recommendations and network prioritization results from the Resilience and Sustainability study to support the development of a Resilience Improvement Plan as well as strategies and recommendations developed in the RGVMPO Transportation Performance Management Framework also completed by DCCM. The incorporation of Performance Management Framework principles enhances how the RGVMPO can gather data on and report progress toward meeting federally required performance goal areas during MTP implementation. The DCCM team incorporated best practices as part of an enhanced community-based public outreach and stakeholder engagement approach. The approach included major outreach events such as setting up tables and booths at the UTRGV Back to School Bash where over two thousand students attended multiple farmers market pop up events, surveys and interviews with community leaders and cooperating agencies, as well as tabling at a critical mass bike ride in Harlingen. All provided opportunities to develop goals, objectives and priorities for program improvements which aided the MPO team in assessing the opportunities to improve mobility choice and options for the regional population. In addition, this has led the MPO into ongoing discussions with regional government entities, agencies, and authorities on gathering and substantiating funding availability to assist with broadening the project implementation program sustained through the financially constrained short, mid-, and long-term implementation program. With their program developed, the DCCM team assisted with updates and scenario evaluation of network performance and operational characteristics using the regional travel demand model. This evaluation allowed the DCCM team to assess and support development of future network improvements capable of building sufficient capacity to accommodate projected changes in land use, economic development, population, network connectivity, and employment.

Cedarspur Drive, Burkhart Road, and Winningham Lane Improvements

Cedarspur Drive, Burkhart Road, and Winningham Lane Improvements Spring Valley Village, Texas DCCM provided the preliminary engineering report, design, survey, and SUE QL-C and D for road paving and utility improvements in three separate areas of the City of Spring Valley Village. The project encompassed the reconstruction of Cedarspur Drive, Burkhart Road, and Winningham Lane East, totaling 2,200 linear feet. It included replacing 6,400 square yards of concrete roadway and driveways, water line, and sanitary improvements. Additional services included attending pre-bid meetings, bid evaluation, and award recommendation. DCCM also attended a preconstruction conference, reviewed shop drawings and requests for information, performed site visits as specified by the client, and provided record drawings. The design of the TCP was challenging because the project consisted of three streets with dead ends, requiring us to maintain two-way traffic while rebuilding a two-lane roadway. We limited work zones to 400 linear feet at a time to make it easier for residents traveling to and from their homes. Ongoing flagging and coordination with residents was imperative for a smooth project. DCCM coordinated closely with the City of Spring Valley Village, the contractor, and affected homeowners to provide a seamless design and construction experience. Homeowners were notified of the schedules, including the start and end times for work on their street. Homeowners were also encouraged to notify the city, the contractor, or the engineer if there were any issues. The project went smoothly with minimal issues.

US 79 Widening

US 79 Widening Jewett, Texas The DCCM team designed a 10-mile schematic and environmental project in Leon County. The project consisted of widening US 79 from a two-lane section to a four-lane divided section from west of Jewett at FM 1512 to Buffalo. This project developed three alternatives and refined the preferred alternative based on stakeholder input from two public meetings, environmental constraints, and limited right-of-way (ROW). The team worked on developing all environmental technical reports required to obtain environmental clearance for ROW acquisition and utility relocation before the final design. One project challenge involved reintroducing a relief route around the City of Jewett during the 90% schematic design. The DCCM team collaborated with the Emerging Technologies group to devise potential relief routes and create exhibits for the upcoming public meeting. Additionally, the DCCM team generated 3D renderings for downtown design options and collaborated with the City of Jewett to gain consensus from key stakeholders. Another challenge involved two grade-separated railroad crossings with BNSF and UPRR. The UPRR crossing featured a rail siding to the Nucor Corporation plant. To address this, seven alternatives were developed to convert the Nucor Corporation at-grade crossing into a grade-separated crossing, ensuring access to Nucor Corporation plants and CR 347. In coordination with Nucor Corporation and TxDOT, the team worked to find a design solution that accommodated all parties while minimizing interchange construction costs.

IH 35 at Ronald Reagan Boulevard Bridge

IH 35 at Ronald Reagan Boulevard Bridge Williamson County, Texas The project included schematic development and plans, specifications, and estimates for realigning Ronald Reagan Boulevard into a divided roadway with two one-way alignments. It included the removal of the existing two-way bridge over IH 35 and the construction of two new one-way bridges over IH 35, while continuing to provide connectivity to CR 247 and CR 311. Ronald Reagan Boulevard improvements started 2,300 feet west of IH 35 and proceeded east to IH 35, and continued east for 500 feet. Beginning at CR 247, the new Ronald Reagan Boulevard tapers to a divided roadway (two lanes in each direction), with one-way eastbound and westbound alignments and paved shoulders. In the future, Ronald Reagan Boulevard will be widened to four lanes from SH 195 to CR 247, providing a major artery from Georgetown to IH 35. The project included new safety lighting, retaining walls on IH 35 for the new bridge abutments, construction of auxiliary lanes on IH 35 under the new bridges, and drainage improvements along Ronald Reagan Boulevard, the frontage roads, and IH 35 mainlanes. The offset distance between the east- and westbound alignments of Ronald Reagan Boulevard also provided an adequate span for future freeway construction and additional widening of the boulevard. Public involvement, utility coordination, private land and business owners, the City of Jarrell, emergency service providers, TxDOT, Williamson County, the Federal Highway Administration, the Texas Commission on Environmental Quality, and other stakeholders were important to project success.

SH 288 Bridge Improvements

SH 288 Bridge Improvements Brazoria County, Texas TxDOT awarded a statewide indefinite deliverable contract for bridge engineering to DCCM for bridge engineering services. For work authorization No. 1, DCCM was awarded a project in Brazoria County to prepare plans, specifications, and estimates for bridges at three intersections along SH 288. The project required the design of new overpass structures at the intersections of SH 288 with CR 57 and CR 64, the widening of an existing structure at SH 288 and CR 56, and two frontage-road creek-crossing bridges. The structural designs ranged from TxDOT-standard multi-column TxGirders for stream crossings to green ribbon overpasses with U-beams and inverted tees with skews, to modified details with TxGirders. The designs addressed utility conflicts, wetland and stream impacts, skewing, and embankment settlement mitigation. We provided bridge layout plan sheets for each bridge and a comparative cost analysis. The team set bridge spans and limits to achieve optimal beam design and vertical clearance. CR 57 Constructed new location CR 57 cross-street bridge (DCCM) Added ramps Added auxiliary lanes Constructed two frontage road bridges CR 64 Constructed new location CR 64 cross-street bridge (DCCM) Added ramps Added auxiliary lanes CR 56 Widened the existing CR 56 bridge (another consultant) Added frontage roads Added auxiliary lanes Design aspects of the project included surveying, geotechnical engineering, bridge design, roadway design, drainage, environmental engineering, and subsurface utility engineering. As the prime provider of the project, DCCM held an e-mail version of the design concept conference before the 30% submittal. The project milestones were 30%, 60%, 90%, 95%, 100%, and the final milestone. DCCM’s engineers coordinated closely with the adjacent segment engineers to assure continuity of design across segment lines. DCCM presented several typical section options to TxDOT prior to beginning the design to ensure TxDOT’s needs were prioritized. The chosen roadway section included a 16-foot median, four 12-foot lanes, two 12-foot shoulders, and a 5-foot, 6-inch sidewalk with C223 rail. The overall roadway width is 103 feet. The project included converting two-way frontage roads to one-way operations. The team used Atlas 14 to determine the floodplain width for the frontage road bridges over West Fork Chocolate Bayou at CR 5.

Avenue S Rehabilitation

Avenue S Rehabilitation Galveston County DCCM provided the design of 8,600 linear feet of roadway reconstruction along Avenue S from 53rd Street to Seawall Boulevard. The paving cross-section comprised two travel lanes with two outside parking areas. The project design included replacing 8,900 linear feet of water line, including branches and intersections along the route, crossing intersections that were previously reconstructed for other concurrent projects. Additionally, a 15-inch sanitary sewer was replaced, stretching from 35th Street to 33rd Street, including branches and intersections. Our assessment of the drainage system along the corridor and side streets enabled us to determine the most effective methods for enhancing drainage efficiency while removing bridge blocks. The flat terrain of Galveston provided grading challenges, and with our detailed 3D grading abilities, the shallow underground storm system had the proper cover under the road and for some instances where standard cover was not achievable, it was discovered and known during the design or it was identified during construction and the design remedies were ready before construction was delayed. Our subconsultants performed geotechnical, surveying, SUE, environmental, and inspection services for the project. DCCM provided construction phase services for the City of Galveston and collaborated with the contractor to ensure the design intent was effectively implemented. The final product of the road was excellent, and the contractor successfully constructed the road and storm sewer system with minimal RFIs and minor adjustments to the road, sidewalks, and storm sewer system grading. All meetings were accompanied by a well-organized agenda and meeting minutes, which included detailed action items to be completed by the next meeting. This attention to detail and accountability helped lead the project to a successful completion and limited citizen complaints. Surveying Services DCCM supported land surveying services for 2.5 miles of Avenue S from 53rd Street east to Seawall Boulevard Drive. Tasks included right-of-way (ROW) determinations, topographic surveying, and subsurface utility surveying to support engineering design. The project included a full-depth replacement of existing pavement and utilities, including water lines and subsurface sanitary and storm sewer systems. Approximately 275 parcels were abstracted to support ROW determinations and graphically depict property ownership. Survey control was established, including ground targets for aerial triangulation of UAS/drone imagery acquired by a subconsultant. Lidar data was also collected, post-processed, and delivered to us for analysis and integration into our survey. Supplemental ground surveying was performed to support the validation of the imagery and lidar data. Final deliverables included 3D mapping in Civil 3D format and rectified orthomosaic imagery of the project extents. SUE Services DCCM provided SUE services along 8,600 linear feet of water and sanitary sewer line from Avenue S from 53rd Street to Seawall Boulevard. The SUE QL-B designation revealed more than 56,000 feet of utilities in that area. As in all SUE projects, the utility mainlines were designated. This project was unusual because all utility services were also designated so that the designers would have substantial utility information and the best chance to protect the utilities in place—this required electronically traceable duct runners, fish tapes, and electromagnetic sweeping.
