(a) This subpart sets forth the requirements for management program approvability with respect to areas of particular concern because of their coastal-related values or characteristics, or because they may face pressures which require detailed attention beyond the general planning and regulatory system which is part of the management program. As a result, these areas require special management attention within the terms of the State's overall coastal program. This special management may include regulatory or permit requirements applicable only to the area of particular concern. It also may include increased intergovernmental coordination, technical, assistance, enhanced public expenditures, or additional public services and maintenance to a designated area. This subpart deals with the following subsections of the Act: 306(d)(2)(C)-Geographic Areas of Particular Concern; 306(d)(2)(E)-Guidelines on Priorities of Uses; 306(d)(2)(G)-Shorefront Access and protection Planning; 306(d)(2)(I)-Shoreline Erosion/Mitigation Planning; and 306(d)(9)-Areas for Preservation and Restoration.(b) The importance of designating areas of particular concern for management purposes and the number and type of areas that should be designated is directly related to the degree of comprehensive controls applied throughout a State's coastal zone. Where a State's general coastal management policies and authorities address state and national concerns comprehensively and are specific with respect to particular resources and uses, relatively less emphasis need be placed on designation of areas of particular concern. Where these policies are limited and non-specific, greater emphasis should be placed on areas of particular concern to assure effective management and an adequate degree of program specificity.
