Rule 391-3-16-.05 - Criteria for Mountain Protection
(1)Background. The following section on background is strictly for the purpose of introduction of the criteria. The section explains the significance of land-disturbing activities on Georgia mountains, the relevant section of the Official Code of Georgia, and the method prescribed by the law for protection of a mountain areas.
(a) The mountain of Georgia are characterized by steeps slopes, thin soils, and, because of the natural stresses placed on such environments, they require special protection. Land-disturbing activity on the high-elevation, steep-slope mountains of Georgia potentially threatens the public health, safety, welfare, and economic progress of the state. Such land-disturbing activity:
1. may endanger the quality of surface water by increasing erosion and stream sedimentation;
2. has the potential to induce landslides;
3. has the potential to adversely affect ground water due to the difficulty in providing proper sewage disposal in areas of steep slope and high elevation;
4. may damage the habitat for some species of wildlife (both plants and animals); and
5. may detract from the mountains' scenic and natural beauty which is vital to the recreation and tourism industry of North Georgia.
(b) The Comprehensive Georgia Planning Act of 1989 provides for the development of coordinated and comprehensive planning by municipal and county governments. Such comprehensive plans shall consider the natural resources, environments, and vital areas within the jurisdiction of the local government. Maintenance of the status as a "Qualified Local Government" is contingent upon the development of such comprehensive plans (O.C.G.A. 50-8-1et seq.).
(c) Section 12-2-8 (as amended) of Article 1, Chapter 2, Title 12 of the Official Code of Georgia Annotated (O.C.G.A.) authorizes the Department of Natural Resources (DNR) to develop minimum planning standards and procedures for the protection of mountains in the state, and requires local governments to use these minimum planning standards in developing and implementing local comprehensive plans.
(d) The method mandated in O.C.G.A. 12-2-8 for the protection of mountain areas is the development of the local plans (as part of the comprehensive plans authorized under O.C.G.A. 36-70-3) that control the extent of the land-disturbing activity on affected mountains.
(2) Definitions.

2. The plans shall consider any characteristics of a protected mountain that make it unique or significant in the conservation of flora and fauna including threatened, rare, and endangered species. The plans shall establish the local government's policies regarding such flora and fauna rather than identifying specific sites containing such species.
3. The plans shall consider the effect of activities within protected mountain areas on ground-water or surface-water quality.
4. The plans shall consider the effect of activities within protected mountain areas on the visual esthetics of the protected mountain.
5. The plans shall consider whether the effects of activities within a protected mountain area are temporary or permanent in nature and, if temporary, the length of time of the impact.
6. The plans shall consider the preservation of significant state historical and archaeological resources (defined as properties on or eligible for the National Register of Historic Places) within protected mountain areas.
7. The plans shall consider the effect of activities within protected mountain areas on immediately adjacent sensitive natural areas. The plans shall establish the local government's policies regarding such adjacent sensitive natural areas rather than identifying specific sites.
(7) Procedures.
(a) Determination of Elevation.

2. Actual calculation of slope shall be done in one of three ways:
(i) Slope may be determined by measuring the proximity of contour lines on a quadrangle map.
(ii) Slope may be determined by using appropriate computer algorithms working on U.S. Geological Survey Digital Elevation Models.
(iii) Slope may be determined by a registered surveyor using standard surveying practices.
3. On an otherwise protected mountain, areas that are at an elevation of 2,200 feet or more and have slope of less than 25 percent, exclusive of valley floors shall be included within the protected mountain area.
4. The crests, summits, and ridge tops of mountains whose flanks meet the criteria for a protected mountain shall also be included within the protected area, even though the slopes of such crests, summits and ridge tops have slope of less than 25 percent.
(c) Preparation of Maps.
1. As part of their Mountain Protection Plans, local governments shall include maps showing all protected mountains within their jurisdiction. These maps shall consist of either:
(i) Quadrangle maps (at 1:24,000 scale) on which the protected mountains have been delineated.
(ii) Plat maps on which the protected mountains have been delineated.
