§ 229.19  SUBDIVISION REGULATIONS.
   (A)   Each lot created through subdivision shall be suitable in its natural state for the proposed use with minimal alteration. Suitability analysis shall include consideration of susceptibility to flooding; existence of wetlands, soil and rock formations with severe limitations for development, or severe erosion potential; steep topography; inadequate water supply or sewage treatment capabilities; near shore aquatic conditions unsuitable for water based recreation; important fish and wildlife habitat; presence of significant historic sites; or any other feature of the natural land likely to be harmful to the health, safety, or welfare of future residents of the proposed subdivision or of the city.
   (B)   The subdivision of any land that will create 2 or more lots, any of which is less than 10 acres in size, shall require platting under the subdivision regulations of the city. This section will not apply to:
      (1)   The subdivision and conveyance of a part of 1 lot of record where the conveyance is to enlarge an existing lot of record; the remaining parcel meets the minimum lot size and area requirements of this chapter; and the parcel conveyed is not itself a buildable lot.
      (2)   The conveyance of a parcel condemned by or deeded to a public authority to be used for public purposes.
   (C)   All lots created by any subdivision shall comply with this and other ordinances of the city.  Where more than 1 standard is applicable to a subdivision, or to any lot therein, the more restrictive standard shall control.
   (D)   Subdivisions shall not be permitted that allow or require on-site sewer systems. This restriction shall not prohibit the approval of subdivisions when due to the immediate unavailability of the city sewer system, the lots in a plat are sized as if the sewer system were available, purchasers are required to acquire a sufficient number of the lots to accommodate an on-site sewer system and required to build upon 1 of the lots meeting all other standards of this chapter and other ordinances, so that at the time the city sewer system is available, all of the lots can be developed as if the sewer system were originally available. When permitted, all of the lots originally acquired by a purchaser shall be treated as a single lot, and shall comply with all of the provisions of this chapter and applicable ordinances.
   (E)   An application for a preliminary plat shall include the following:
      (1)   Topographic contours at not less than 10 foot intervals; provided that if the topography is critical in determining compliance with the provisions of this chapter, the city may require a topographic map having intervals of less than 10 feet;
      (2)   The surface water features required in M.S. § 505.02(1);
      (3)   Adequate soils information to determine suitability for building and on-site sewage treatment capabilities for every lot from the most current existing sources or from field investigations such as soil borings, percolation tests, or other methods;
      (4)   Information regarding adequacy of domestic water supply; extent of anticipated vegetation and topographic alterations; near shore aquatic conditions, including depths, types of bottom sediments and aquatic vegetation; and proposed methods for controlling stormwater runoff and erosion, both during and after construction activities; and
      (5)   Location of 100-year floodplain areas from existing maps or data.
   (F)   The city may require a conveyance or dedication of land for easements for ponding and the natural drainage of surface water and the management of wetlands.
