Methodology Illustration by EEPThe N.C. Ecosystem Enhancement Program uses a watershed approach to determine priority areas for implementation of stream- and wetland-mitigation projects. The purpose of this approach is to concentrate mitigation resources in areas where they will have the greatest benefit to local watershed functions. EEP’s watershed approach includes three major steps, beginning at the scale of river basins, proceeding to local watersheds [14-digit Hydrologic Units (HUs)], and culminating in the identification of project sites (stream reaches, wetland sites and adjoining areas) within priority sub-watersheds.
