17.28.010 INTENT AND PURPOSE.

(A)    It is the intent of the Matanuska-Susitna Borough to recognize the value and importance of promoting the utilization of natural resources within its boundaries. The purpose of this chapter is to establish an interim materials district within the Matanuska-Susitna Borough to allow resource extraction activities as an interim use of land while promoting the public health, safety, order, prosperity, and general welfare of the Matanuska-Susitna Borough through regulation of land use to reduce the adverse impacts of land uses and development between and among properties. It is the further purpose of this chapter to promote compatible, orderly development. These purposes are accomplished by:

(1)    designating areas for the extraction of earth materials important for the development of the Matanuska-Susitna Borough;

(2)    enhancing the character and stability of residential, agricultural, business, commercial, and industrial areas, and promoting the orderly and beneficial development of such areas by the owner/permittee in a manner that will not devalue the extraction site or neighboring properties for future beneficial uses upon completion of gravel extraction;

(3)    promoting diversified land use and economic opportunity;

(4)    encouraging the most appropriate uses of land;

(5)    enhancing the natural, manmade, and historical amenities of the Matanuska-Susitna Borough;

(6)    recognizing and preserving traditional uses of land within the Matanuska-Susitna Borough; and

(7)    protecting and enhancing the quality, peace, quiet and safety of the Matanuska-Susitna Borough neighborhoods.
