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.

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 (H&H) 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. The survey information was provided in MicroStation Select Series 10.
