If a county requires approval of plats as a prerequisite to the subdivision of land, whether such requirement be adopted in compliance with this chapter, or be adopted, whether prior to or subsequent to July 1, 1981, pursuant to other authority, from and after July 1, 1981: 1. No subdivision of any lot, tract, or parcel of land shall be made, no street, sanitary sewer, water main, or other improvements in connection therewith shall be laid out, constructed, opened, or dedicated for public use or travel, or for the common use of occupants of buildings abutting thereon, except in accordance with a plat as finally approved by the board of county commissioners. 2. No plat shall be finally approved or disapproved by the board of county commissioners except upon receipt of recommendations by both the county planning commission and the board of township supervisors of the township in which the proposed subdivision is located. The board of county commissioners shall, by certified mail, notify the chairman of the board of township supervisors that an application for plat approval has been initiated, either before the county planning commission or before the board of county commissioners, and that the board of township supervisors is requested to make a recommendation on the application. If the board of county commissioners does not receive, by certified mail, a recommendation by the board of township supervisors within sixty days after notification, it may take final action on the application for plat approval. The recommendations by either the county planning commission or the board of township supervisors shall not be binding on the county commissioners. 3. In determining whether a plat shall be finally approved or disapproved, the board of county commissioners shall inquire into the public use and interest proposed to be served by the subdivision. It shall determine if appropriate provisions are made for the public health, safety, and general welfare, for open spaces, drainage ways, streets, alleys, other public ways, water supplies, sanitary wastes, parks, playgrounds, sites for schools and school grounds, but its determination is not limited to the foregoing. The board shall consider all other relevant facts and determine whether the public interest
will be served by the subdivision. If it finds that the proposed plat makes appropriate provisions for the public health, safety, and general welfare and for such open spaces, drainage ways, streets, alleys, other public ways, water supplies, sanitary wastes, parks, playgrounds, sites for schools and school grounds, and that the public use and interest will be served by the platting of such subdivision, and that the proposed plat complies with a county resolution, if any, regulating or restricting the subdivision of land, to the extent that such resolution does not conflict with the provisions of this section, such plat shall be finally approved with such conditions as the board of county commissioners may deem necessary. If it finds that the proposed plat does not make appropriate provisions, or that the public use and interest will not be served, or that the proposed plat does not so comply with the aforementioned resolution, then the board of county commissioners shall disapprove the proposed plat. Dedication of land to any public body may be required as a condition of subdivision approval and shall be clearly shown on the final plat.
11-33.2-12.1. Contents of plat - Location and elevation of lakes, rivers, or streams - Notification of floodplain. Whenever land, subject to regulation under this chapter, abutting upon any lake, river, or stream is subdivided, the subdivider must show on the plat or other document containing the subdivision a contour line denoting the present shoreline, water elevation, and the date of the survey. If any part of a plat or other document lies within the one hundred year floodplain of a lake, river, or stream as designated by the department of water resources or a federal agency, the mean sea level elevation of that one hundred year flood must be denoted on the plat by numerals. Topographic contours at a two-foot [60.96-centimeter] contour interval referenced to mean sea level must be shown for the portion of the plat lying within the floodplain. All elevations must be referenced to a durable benchmark described on the plat with its location and elevation to the nearest hundredth of a foot [0.3048 centimeter], which must be given in mean sea level datum.
