Environmental Resolutions, Inc. (ERI) performed an extensive topographic survey for the purpose of assisting Burlington County’s design firm in the development of a Feasibility Study for the Centerton Road Pedestrian/Bicycle Bridge.  It had previously been determined that the existing vehicular bridge (which had failed numerous safety inspections) was too costly to replace and did not alleviate traffic as a connector to Route 295, and so was slated for demolition.  A feasibility study was undertaken with the understanding that the pedestrian bridge could be developed as an integral component of the proposed County trail system. The bridge would provide interconnectivity between the Rancocas Point Trail in Mt. Laurel and the proposed Centerton Point Park to be located on County owned land in Westampton. A pedestrian bridge would also provide additional opportunities for recreational activities and amenities such as fishing and canoeing/kayaking.

ERI was tasked to provide accurate base plans showing:

  • Roadway details
  • All physical improvements
  • Drainage structures and utilities.

Project limits were from the centerlines of the project limits to 50 feet beyond the toe of slopes each side of the roadway for approximately 600 feet and beyond the abutments.  Survey included the elevation of the bridge deck and underside of structure (bottom chord) so that the design firm would be able to provide one hundred ten (110) details of the existing bridge superstructure (truss, deck), intermediate piers, fender system, etc. to the County for the study.

ERI also surveyed the adjacent residential dwellings and driveways within the project limits for location, footprint, elevations, etc.

All signs, light poles, utility poles and overhead wires, guiderails, evidence of subsurface utilities, ditches, stream crossings, edge of woods, driveway aprons, curb returns, striping, and wetlands flags were located and mapped.

ERI’s drafting personnel utilized this “field to finish” data to produce the plan view base map for the project. Utilizing the point data, the draftsperson produced an alignment and surface 3D terrain model.  One foot (1 ‘) contours are created from the model and analyzed for accuracy then TIN lines were adjusted to refine the graphical representation of existing topography.

The drawings were “polished” to visually communicate the required level of detail of the existing site conditions and provided to the design firm.
