This is an amendment to a law, and sure sounds weird.
(b) No county, municipality, or other local public body shall adopt any rule, ordinance, policy, or planning guideline addressing sea-level rise, unless it is a coastal-area county or is located within a coastal-area county.
(c) No rule, ordinance, policy, or planning guideline that defines the rate of sea-level rise shall be adopted except as provided by this section.
(d) The General Assembly does not intend to mandate the development of sea-level rise policy or rates of sea-level rise. If, however, the Coastal Resources Commission decides to develop rates of sea-level rise, the Commission may do so, but only by instructing the Division of Coastal Management to calculate the rates.
(e) The Division of Coastal Management shall be the only State agency authorized to develop rates of sea-level rise and shall do so only at the request of the Commission. These rates shall only be determined using historical data, and these data shall be limited to the time period following the year 1900. Rates of sea-level rise may be extrapolated linearly to estimate future rates of rise but shall not include scenarios of accelerated rates of sea-level rise. Rates of sea-level rise shall not be one rate for the entire coast but, rather, the Division shall consider separately oceanfront and estuarine shorelines. For oceanfront shorelines, the Division shall use no fewer than the four regions defined in the April 2011 report entitled “North Carolina Beach and Inlet Management Plan” published by the Department of Environment and Natural Resources. The oceanfront regions are: Region 1 (Brunswick County), Region 2 (New Hanover, Pender, and Onslow Counties and a portion of Carteret County), Region 3 (a portion of Carteret County and Hyde County), and Region 4 (Dare and Currituck Counties). For estuarine shorelines, the Division shall consider no fewer than two separate regions defined as those north of Cape Lookout and those south of Cape Lookout.
(f) Any State agency, board, commission, institution, or other public entity thereof and any county, municipality, or other local public body that develops a policy addressing sea-level rise that includes a rate of sea-level rise shall use only the rates of sea-level rise developed by the Division of Coastal Management as approved by the Commission. If the Commission has not approved a sea-level rise rate, then the sea-level rise policy shall not use a rate of sea-level rise.
Why are they trying to define in a law precisely how you are allowed to measure a physical quantity, and why are they trying to decree that only linear rates are permissible? It sounds like they are trying to legislate reality.
But maybe some Carolinians in the know can explain the logic of their legislature.
