A Final Subdivision Plan (FN) is required for all subdivisions of land resulting in the creation of three (3) or more lots, or for any residential subdivision where public improvements are proposed. A landowner who wishes to subdivide property must comply with all applicable County requirements for design, dedication improvement and restrictive use of land. Subdivision regulations assure the orderly development of land, and protect the health, safety and welfare of the general public, as well as future property owners in the subdivision. The Land Development Division administratively approves final subdivision plans and plats.  Final subdivision plans take approximately three to five months for approval. The plans are valid for five years, within which time the performance bond must be posted, plats must be recorded, and site development permits must be obtained.   A Final Subdivision Plan Revision (RV) is required when any change to the original final subdivision plan is proposed.   The following forms are required when submitting a final subdivision plan or revision to a final subdivision plan:   Final Site and Subdivision Plans and Revisions Checklist Final Plat Checklist Legal Instrument (Deed) Checklist Development Control Form Residential Site/Subdivision Fee Calculation Sheet Unit Price List (if applicable) Final Site and Subdivision Plans and Plats and any necessary supporting documents for a proposed project constitute the complete application for construction approval. A final plan includes detailed engineering and layout drawings for the public and private improvements, in addition to any necessary engineering calculations required for review. Upon approval, final plans and plats form the basis for the construction of the project, and are used by the Department of Public Works and the state to inspect the project.
