The NCDOT has requested stream origin mapping for all of the eco-regions in North Carolina to be able to better understand drainage basins and manage future mitigation projects efficiently.

The streams being surveyed are located in various regions of North Carolina, including the mountains, piedmont, sandhills, and coastal plain areas.

SEPI environmental scientists are responsible for using topographic maps and GPS unit to locate and record stream origin points. This is a statewide effort focusing on eight regions of the NCDOT. Using available data sets, field data collection, and predicative modeling techniques, the NCDOT expects to utilize the most current and accurate data to streamline project delivery through increased use of GIS-based data layers and analysis.

The field assessments and stream origin mapping will inform future mitigation practices to reduce sediment deposits and help protect habitat diversity and riparian vegetative areas through improved bank stability and natural channel flow.
