(A) Plats shall be filed on any parcel that is subdivided into a non-aliquot part of the United States Public Land Survey System (USPLSS); an aliquot part of the USPLSS of less than 40 acres; or not a recorded government lot, Homestead Entry Survey (H.E.S.) or Mineral Survey (M.S.). The governing body, upon completion of a review per requirements of § 154.21(A), may waive the requirement to create and file a plat for subdivision into aliquot parts of the USPLSS when the requirements of § 154.22(A)(3) have been met.
(B) The subdivider is required to install or construct the improvements hereinafter described prior to receiving approval of the final plat unless the governing body accepts appropriate surety in lieu of construction. All improvements required under this chapter shall be constructed in accordance with specifications provided by and under the inspection of the Planning Coordinator and/or the Town Engineer or their representative. Appropriate surety shall be deemed to be cash or certified check or surety bond paid to the Finance Officer in an amount to be recommended by the Town Engineer for the estimated cost of the improvements plus a 30% reserve. The reserve is intended to cover potential town costs, such as, but not limited to, engineering review, construction administration, construction inspection, project management and general administrative costs, in the event of default or noncompliance with town specifications by the subdivider.
(C) All public streets shall be constructed to town street specifications. The street construction shall be subject to inspection by both the Town Engineer and the Planning Coordinator during construction and upon completion.
(D) Maintenance of public streets that have not been accepted for maintenance purposes by the town, or by any other governmental entity, shall be the responsibility of adjacent landowners unless the maintenance is accepted by the governing body. Landowners are encouraged to form a Road District Association as specified in SDCL § 31-12A but may petition the governing body for acceptance of maintenance by the town as follows.
(1) This petition shall contain a description of the exact location of the street to be maintained by the town.
(2) A statement shall be included describing the requested maintenance or improvements the petitioners desire the town to undertake. This statement is to be of sufficient detail to enable the Town Engineer and the Board of Trustees to reasonably determine the likely costs of the proposed action.
(3) An explanation shall be provided detailing why a Road District Association cannot or should not be formed.
(E) Private access roads are allowed and shall be indicated on plats within private access easements. Private access roads are intended to serve only one parcel. The Board may allow a private access road to be shared by two adjoining parcels where topography or access restrictions onto federal, state or county highways or town streets make the sharing desirable. Development of private access roads is not required.
(F) Storm sewers and drainage structures shall be designed and installed as recommended by the Town Engineer and in accordance with good engineering practice. Culverts shall be designed to withstand the effects of a 25-year, 24-hour rainfall and may be required to be certified as such by a professional engineer. Culverts shall be concrete or corrugated metal pipe and shall have a diameter of at least 18 inches unless otherwise first approved for use by the Town Engineer.
(G) All property corners, including the beginning (point of curvature) and ending (point of tangency) of curves along property lines, shall be accurately marked on the ground with a five-eighths inch to one and a quarter inch diameter iron rod at least 18 inches in length. These bars are to be capped with an aluminum or plastic cap indicating the license number of the surveyor who placed the bar in the ground.
(H) The subdivider shall contract with the County Highway Department for the installation of durable street name signs at all public street intersections. Two street name signs are required for all intersections within municipal limits.
(I) All required improvements in the subdivision shall be installed under the inspection of the Planning Coordinator and/or the Town Engineer.
(J) The Planning and Zoning Commission may formulate additional written administrative rules that govern the procedure for processing subdivisions. These procedures will outline the responsibility of parties concerned with subdivisions and processing, and they will contain other information necessary to systematize handling and processing.
(K) Platting fees shall be set by the governing body.
