The boundary of a federally approved coastal program defines a geographic area that receives special planning and management attention through regulations, financial assistance, and technical support. Section 306(d)(2)(A) of the federal Coastal Zone Management Act provides the basis for determining the coastal boundary. In Section 304 of the act, the coastal zone refers to coastal waters (and the lands below them) and the adjacent shorelands, “strongly influenced by each other and in proximity to the shorelines of the several coastal states, including transitional and intertidal areas, salt marshes, wetlands, and beaches. The zone extends…seaward to the outer limit of State title and ownership under the Submerged Lands Act (43 U.S.C. 1301 et seq.), the Act of March 2, 1917 (48 U.S.C. 749).” The inland boundary must include those lands necessary “to control shorelands, the uses of which have a direct and significant impact on the coastal waters, and to control those geographical areas which are likely to be affected by or vulnerable to sea level rise.”
