Bayland Island Development

Bayland Island Development Baytown, Texas DCCM provided the surveying associated with the development of this 27-acre peninsula (island) located south of SH 146, just east of the Fred Hartman Bridge in the City of Baytown. Close coordination was conducted with the City of Baytown officials, title companies, and developers. The survey included detailed abstracting of a chain of title for mineral leases, pipelines, and real property records. The firm performed shoreline boundary surveys of tidally influenced areas, boundary surveys of upland areas, and topographic surveys of the island. Additionally, DCCM prepared an American Land Title Association/National Society for Professional Surveyors survey of the island and roadway access from SH 146, as well as a 6.8-acre portion of the island for development. The firm also coordinated utility and access easements and prepared and coordinated the platting of the entire project. An existing marina sports bar and grill facility is located on the island. Locating and identifying existing utility easements and utilities that served the island was difficult, especially a non-visible sanitary sewer force main. The DCCM office personnel and field crew worked closely with the City of Baytown’s public works department, subsurface utility engineering consultants, and others to excavate and locate the buried utility in various places and obtain an accurate location and depth of the line. Another challenge faced during the project was coordinating with engineers, architects, city planners, and various city departments. DCCM implemented a solution by conducting regularly scheduled team progress and scheduling meetings. These meetings were crucial in ensuring the project remained on track and continued progressing productively. Additionally, weekly progress reports were provided to the City of Baytown to inform them about the project’s status. Through this experience, it was learned that regular meetings with the entire team not only help prevent potential issues but also promote organization and accelerate the project’s overall progress.

Cedar Bayou Crossing Corridor Study

Cedar Bayou Crossing Corridor Study Harris County and Baytown, Texas DCCM was selected to provide professional services for the proposed Cedar Bayou crossing. The crossing will serve as a critical link for the City of Baytown to ensure the orderly development of the northern part of the city and provide necessary east-to-west mobility to supplement IH 10. The project area was from Hunt Road at Main Street to Kilgore Parkway at SH 146. DCCM provided project management, data collection, existing condition evaluation, alternative analysis, community outreach support, preliminary engineering, geotechnical investigation, subsurface utility engineering, survey, and an environmental analysis. DCCM conducted a corridor study to identify alignment alternatives and assess the project’s feasibility. The study included several aspects to consider and required sufficient information to measure and evaluate a range of viable improvement options. The traffic analysis reviewed traffic and crash data, existing roadways, traffic flow patterns, traffic counts, turning movement counts, and transit and traffic operations. The DCCM team conducted capacity analyses for designated locations and sections of roadways and made recommendations to improve traffic flow. DCCM provided hydrology and hydraulics to support the corridor layout of the proposed roadway. This task used the latest Mapping, Assessment, and Awareness project (MAAPNext) models for Cedar Bayou as developed by the Harris County Flood Control District. DCCM also provided community outreach, public meetings, and City Council meetings. The project concluded with identifying recommended improvements, preliminary plans with several alternatives and their estimated costs, and a preferred alignment. Surveying Services DCCM performed professional surveying services to obtain and review existing lidar data and the limited preliminary ground survey data for the Cedar Bayou Corridor Study. The project spanned 3.7 miles from North Main Street, 3,300 feet south of IH 10 (west tie-in point), to the intersection of SH 146 and Kilgore Parkway (east tie-in point). The latest available lidar data published from USACE and Texas Natural Resources Information System covering the project area to evaluate and perform the following tasks: Data sets were extracted/downloaded into Esri ArcGIS (Pro+3D Analyst tool) and Context Capture/OpenRoads Cross-data checks were performed against public datasets from TxDOT, the City of Baytown, Harris County, and other available online resources. The MicroStation DGN deliverable included: DEM 2D building/structure footprints Roads, highways, and railroads Overhead transmission lines Other visible features within the lidar data Limited field surveying was performed. Field surveying tasks included setting four project control points, performing limited topographic surveying along North Main Street (1,000 feet north and south of the west tie-in point) and SH 146 (500 feet north and south of the west tie-in), and obtaining cross sections along the existing railroad running through the project. Field surveying also included determining the elevations of the existing railroad running at the railroad bridge over SH 146 and confirming (spot-checking) the lidar data in several accessible areas. The survey data was based on the NAD 83, Texas Coordinate System, South Central Zone (4204) CORS adjustment. Elevations were based on the NAVD 88 2001 adjustment relative to the lidar data.

Dogwood Trail Boundary Survey

Dogwood Trail Boundary Survey Tyler County, Texas DCCM determined boundaries for a privately held timber company tract of land and performed research of Texas General Land Office archives, Hardin County records, and private survey records. Fieldwork in the area determined the location of existing occupation, monumentation, topographic features, and natural features. The evidence was analyzed and compared with the recorded evidence, and, where appropriate, lines were marked with lathes that were intervisible. Plats that included trails and natural features for park use and metes and bounds were prepared for use in the land transfer. The resulting 40-acre partition was transferred to the Big Thicket Natural Heritage Trust. At a Glance 40 Acres $7,000 Survey Project Cost Markets Surveying Services Surveying

Marion County Boundary Survey

Marion County Boundary Survey Marion and Jefferson Counties, Texas DCCM determined the boundary of an original survey in Marion County and the boundary determination of numerous tracts of land surrounding and adjacent to the subject survey. Due to natural and artificial changes in the area since the 1800s, the project required extensive research outside the normal record research involved in any survey project. Research was performed in the Texas General Land Office archives, Marion County records, and private survey records. Historic research of the area was also necessary, including historical aerial photography and topographic maps. Fieldwork utilized existing occupation, monumentation, and natural features as called for when the grants were originally laid out. Evidence was analyzed and compared to records. A report and plat were prepared, setting out all boundaries, the issues affecting the area, and the topographic features. Project Manager Nedra Foster Townsend, LSLS, RPLS, and Texas Parks and Wildlife Department personnel attended meetings with surrounding landowners to explain boundaries.

Neches Wildlife Management Area Tract Acquisition

Neches Wildlife Management Area Tract Acquisition Cherokee County, Texas DCCM was selected to survey the boundaries of 250 acres in Cherokee County, which included several miles of Neches River gradient boundary, a river cut-off area, highway frontage, oil and gas operations, utility easements, and a railroad transecting the tracts. DCCM requested the right of entry, the setting of control, the location of existing monumentation, and the setting of new monumentation where needed, preparation of plats, and legal descriptions for transactions. Services DCCM conducted deed research to ascertain current record ownership and parent tracts, as well as easements, utilities, and oil and gas records. Records from TxDOT and the Missouri Pacific Railroad were acquired. Research on original grants was conducted using GLO archival records. Historic aerial photographs and topographic maps were used to determine the nature of changes in the river course. We set benchmarks that other entities can access and rely on for GPS-based transactions. The gradient boundary was surveyed on the Neches River in accordance with Oklahoma v. Texas, 260 US 606 (1923). A cut-off of the river (also a county line) had occurred, so this required ascertaining whether the state maintained a claim to the cut-off and to the river’s flow. All corners, lines, and improvements were included in this survey. Plat and metes-and-bounds were prepared for the three tracts comprising 250 acres.

FM 2818 (Harvey Mitchell Parkway) Improvements

FM 2818 (Harvey Mitchell Parkway) Improvements College Station, Texas The FM 2818 (Harvey Mitchell Parkway) project in College Station showcases coordinated planning and innovative design to address regional growth and evolving transportation needs. DCCM led efforts with the City of College Station, TxDOT, Texas A&M University, and Easterwood Airport to improve corridor operations and support future expansion. DCCM’s scope included topographic surveying, ROW and easement identification, corridor and traffic analysis, conceptual alternatives analysis, environmental documentation, public involvement, subsurface utility engineering (SUE), and management of eight subconsultants. The team completed both schematic and PS&E phases, producing a geometric design from Wellborn Road to F&B Road and transitioning efficiently to construction documents by maintaining consistent staff and project management. A detailed topographic survey was completed for the 1.8‑mile corridor, covering an unusually large 80‑acre ROW. Prior baseline data from the 1970s and earlier DCCM utility surveys ensured accurate property and easement mapping. A comprehensive corridor and traffic analysis showed conventional intersections would not meet long‑term capacity needs. DCCM evaluated additional conceptual alternatives and identified a “superstreet” (Restricted Crossing U‑turn) as the preferred solution, reducing signal phases, improving traffic flow, and preserving flexibility for future controlled‑access upgrades. Environmental constraints along White Creek required careful grading and barrier design to minimize impacts on wetlands and floodplains. DCCM kept impacts below permitting thresholds and avoided additional ROW acquisition. DCCM also performed extensive SUE Quality Level (QL) B investigations covering more than 265,000 linear feet of utilities, revealing critical conflicts. Twenty-four QL-A test holes confirmed existing conditions and guided necessary design refinements. At the same time, additional QL-B work on side streets ensured a complete understanding of utility impacts despite tight timelines and traffic-control constraints. The project faced several significant design challenges, including a major underground electric duct bank that conflicted with proposed roadway and drainage improvements. Through SUE QL-A investigations and coordination with the City of College Station and TxDOT, the team adjusted the drainage while leaving the duct bank in place, thereby avoiding costly relocations. The late addition of the Jones‑Butler Road overpass required rapid schedule and design modifications without affecting the letting date.

SH 249 (Tomball Tollway), Phases I and II

SH 249 (Tomball Tollway), Phases I and II Tomball and Montgomery County, Texas DCCM was contracted by the Harris County Toll Road Authority (HCTRA) as the Program Management Consultant (PMC) for the design and management of both preliminary and final project designs, as well as construction management and inspection services for Phase II. We developed a project feasibility assessment, which resulted in the SH 249 (Tomball Tollway), Phases I and II engineering feasibility report, and served as the basis for the final design. On its first day of operation, eager toll users doubled the projected 17,000 daily toll transactions, cutting traffic on the existing frontage road in half. Funded entirely with toll road revenue paid by drivers who choose to use the Harris County toll road system, the final construction will extend the toll road into Montgomery and Grimes Counties to SH 105, streamlining trips to and from rapidly growing Grimes County and College Station. Phase I: Spring Cypress Road to FM 2920 This project provided travelers with four main lanes in each direction and was constructed between the existing TxDOT northbound and southbound non-tolled frontage roads. As PMC for HCTRA, DCCM completed an aggressive 9-month design program to deliver plans, specifications, and estimates (PS&E) for HCTRA to bid and construct this phase. DCCM provided leadership, schedule adherence, quality assurance, and oversight to 17 consultants, completing the PS&E for four new toll lanes in each direction along a 6-mile stretch of SH 249, adding five new bridges, retaining walls, and a drainage system that mitigates flooding. Drivers may now bypass seven stoplights while the frontage roads remain toll-free. All milestone submittals were met on time, and the project was constructed in only 16 months and under three construction contracts. Phase I was open to traffic in April 2015 and is exceeding all revenue forecasts. Phase II: FM 2920 to Spring Creek (Harris/Montgomery County line) Design preparations for Phase II began in October 2014 with design revisions to the TxDOT 2006 SH 249 Schematic. As in Phase I, DCCM was the PMC for the design of four-lane toll lanes in each direction, adding three-lane frontage roads on both north- and southbound approaches, five major bridges, flood-mitigating storm sewer detention, a collegiate practice field, and equestrian and bike trails. Services also included computing cut-and-fill quantities for roadway sections, concrete and reinforcement steel quantities for bridge deck pours, and payments for such pours on the contractor’s pay estimate. DCCM monitored the roadway excavation, subgrade preparation, concrete milling, embankment placement for abutments, installation of drill shaft and foundations, concrete beam placement, asphalt pavement placement, bent footings, column, cap pours, reinforced earth walls, 18- to 36-inch reinforced concrete pipes, and various concrete box culverts. Our team oversaw construction management and inspection services for this segment of the project. Phases I and II of the SH 249 (Tomball Tollway) project included environmental investigations and permitting, survey/ROW mapping, utility identification and assessment, subsurface utility engineering, and hydrologic and hydraulic modeling and detention pond design. DCCM also provided construction phase services for Phase II and the direct connectors at SH 99 (Grand Parkway). Mainlanes, Phase I, Section 1 – Montgomery County MCTRA selected DCCM to prepare PS&E for mainlane and ramp construction for a 0.4-mile section of tollway north of Tomball, Texas. The project scope included roadway geometric design, traffic control plans, removal plans, drainage plans with both open and closed systems, SWPPP, cross-sections, general notes, specifications, and construction cost estimates. The DCCM team coordinated with both adjacent designers on the Montgomery County segment and with the design and construction teams of the Harris County segment to the south to deliver a synchronized product that minimized impacts to travelers and adjacent property owners and reduced overall project costs.
