BRH provided boundary and topographic mapping along the trail, depicting elevations, vegetation, utilities, and surface features. Potholing for utility investigation was required, as was delineation mapping of the wetland limits.
BRH provided engineering scale topographic surveys with contours and spot heights, identified utilities and all surface improvements. Potholes were also located to support site investigations and we located wetland flags. Our surveys supported environmental investigations and the installation of new drainage and irrigation systems.
