(A) Land suitability. Each lot created through subdivision must be suitable in its natural state for the proposed use with minimal alteration. Suitability analysis by the city shall consider susceptibility to flooding, existence of wetlands, soil and rock formations with severe limitations for development, 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) Consistency with other controls. Subdivisions must conform to all official controls of the city. A subdivision will not be approved where a later variance from one, or more, standards in official controls would be needed to use the lots for their intended purpose. In areas not served by publicly-owned sewer and water systems, a subdivision will not be approved unless domestic water supply is available, and a sewage treatment system consistent with the provisions of this subchapter can be provided for every lot. Each lot shall meet the minimum lot size and dimensional requirements herein, including at least a minimum contiguous lawn area that is free of limiting factors sufficient for the construction of two standard soil treatment systems. Lots that would require use of holding tanks must not be approved.
(C) Information requirements. Sufficient information must be submitted by the applicant for the city to make a determination of land suitability. The information shall include at least the following:
(1) Topographic contours at ten-foot intervals, or less, from the United States Geological Survey maps, or more accurate sources, showing limiting site characteristics;
(2) The surface water features required in M.S. § 505.21, as it may be amended from time to time, to be shown on plats obtained from the United States Geological Survey quadrangle topographic maps, or more accurate sources;
(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;
(5) Location of 100-year floodplain areas and floodway districts from existing adopted maps or data; and
(6) A line, or contour, representing the ordinary high water level, and the minimum building setback distances from the lake or stream.
(D) Dedications. When a land, or easement, dedication is a condition of subdivision approval, the approval must provide easements over natural drainage, or ponding, areas for management of stormwater and significant wetlands.
(E) Platting. All subdivisions that create five, or more, lots or parcels that are two and one-half acres, or less, in size shall be processed as a plat, in accordance with M.S. Chapter 505, as it may be amended from time to time. No permit for construction of buildings, or sewage treatment systems, shall be issued for lots created after these official controls were enacted, unless the lot was approved as part of a formal subdivision.
(F) Controlled access or recreational lots. Lots intended as controlled accesses to public waters, or for recreational use areas, for use by non-riparian lots within a subdivision must meet, or exceed, the sizing criteria provided for herein.
