Local government entities are encouraged by federal management agencies to provide for the protection of wild and scenic river values in their land use plans, including the use of zoning and other land use measures.
State land-use requirements often require each local jurisdiction to address uses and activities within wild and scenic river areas in their planning updates. Such local planning may be carried out by comprehensive plan policies, zoning requirements, negotiations with landowners, or through other mechanisms.
