Chapter Five of the SLDCestablishes the regulations that relate to the division of land into two or more parcels for any purpose. All lot divisions must comply with the lot size and zoning requirements of the SLDC. Subdivisions are classified as major or minor; major subdivisions require preliminary plat approval by the Land Use Administrator, affirmative opinions from reviewing agencies and tribal governments, a public hearing on the application and final plat approval.

Separate procedures are prescribed for review of major and minor subdivisions in Table 4-1 to reflect differing levels of complexity in the applications. Before any land is subdivided, the applicant shall apply for and secure approval of the proposed subdivision in accordance with the following procedures:

Major Subdivision: In the case of major subdivisions, the procedure shall include two principal steps: (i) preliminary plat approval and (ii) final plat approval.

Minor Subdivision: In the case of minor subdivisions, the procedure shall include administrative approval of the final plat in a single step known as summary review. Preliminary plat review is not required for minor subdivisions.
