Performing extensive topographic survey and GPS leveling to support the success of a taxiway relocation.

Portions of Taxiway C at the Prescott Regional Airport (PRC) needed to be relocated to meet the minimum Federal Aviation Administration (FAA) requirement of 400 feet of separation from existing parallel Runway 3R-21L. In addition to the relocating Taxiway C, the verified/identified Hot Spots No. 3 and 4 were also mitigated as part of this project since those hot spots were located adjacent to the relocation project.

Survey tasks included topographic features, survey shots of pavement, and other relevant features throughout the project area. The limits of the new topographic mapping centered around the improvement area. The team surveyed any visible drainage infrastructure near the improvement area for use in the design. The survey included horizontal and vertical locations of existing pavements, facilities, utilities, and catch basin elevations impacted by this project. Dibble used the existing datum control for the airport to facilitate the topographic survey effort. We used Global Positioning Systems (GPS), conventional, and differential leveling to establish the required temporary control.
