Portions of the site including area of proposed park entrance, existing buildings, storm pipes, buildings and utilities marked by Missouri One Call were located utilizing Trimble Robotic Total Station. Remainder of site was flown with Drone with LiDAR capable of penetrating tree cover and brush. Drone data and ground survey were combined to create 1′ contours on the entire site. Property corners were located and existing boundary survey was inserted into the topographic survey to be used as a base for the new park improvement plans.
