USACE Ball Mountain Dam
Bryant performed a high-resolution LiDAR (laser) 3D scan of the upstream and downstream faces of the Ball Mountain Dam, which is an earthen dam, and is approximately 265-feet high by 915-feet long. The flood control system consists of an embankment dam, spillway, inlet riser, and an outlet works.
From the scan, two surveys were produced. A conventional on-ground topographic survey of the surrounding terrain of about 65 acres, including major ledge outcroppings, terrain and downstream river cross sections, and a point cloud survey, which can be used to cut sections through the dam in any direction or quantity desired. Both surveys were delivered in Microstation format
The survey is in support of design of a new proposed bridge and access roadway as well as to provide a basis for monitoring the Dam for any settlement or other movement over time.
