Streambank topographic lidar survey of the French Broad River near the Interstate 26 bridge located south of Asheville, NC – November 2019, Pre-construction

In January 2020, the North Carolina Department of Transportation (NCDOT) began work on the Interstate 26 (I 26) highway widening project that involves a bridge crossing over the French Broad River (FBR) near Asheville, North Carolina. The U.S. Geological Survey (USGS) in cooperation with the NCDOT, conducted a streambank light detection and ranging (lidar) survey of the streambanks of the French Broad River in November of 2019, approximately two months before construction began. The survey extended from 300 meters (m) upstream to 700 m downstream from the bridge. Two georeferenced lidar scans were collected; one of the right-descending bank and one of the left-descending bank. Three-dimensional points of the streambank were collected [...]
