CobbFendley developed plan and profile sheets for an NMDOT permit for the Tri-State PEGS supplement waterline. Profiles were developed along a 22-mile stretch of an existing 24” waterline. Aerial photogrammetry supplemented with UAV imagery were utilized to develop  a topographic map along the corridor. Once topographic information was complete profiles were cut utilizing the mapping. The waterline was located using radio detection equipment and was then supplemented by 69 test holes to obtain high accuracy horizontal and vertical information on the existing waterline. As-built plan and profiles were than developed adhering to NMDOT specification.
