Provides definitions for coastal wetlands and marshlands as the terms are used in the proposed statute. Specifies factors to be considered in delineating the protective riparian buffer for any of the coastal wetlands or marshlands in the Neuse River Basin or the Tar-Pamlico River Basin. Effective October 1, 2011.
