In addition to Chapter 153 of this Code of Ordinances, all subdivisions and developments in the Shoreland Overlay District of the city shall comply with the following provisions:
(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 community.
(B) Platting. All subdivisions that create five or more lots or parcels that are two and one-half acres or less in size must be platted in accordance with M.S. Chapter 505. No person may record parcels or receive building, sewage, or other permits for lots that are not part of an officially platted subdivision.
(C) Consistency with other controls. Subdivisions must conform to all other official controls adopted by the city. In areas not served by publicly-owned sewer and water systems, subdivisions may not be created unless domestic water supply is available and soil absorption sewage treatment can be provided for every lot. A lot shall meet the minimum lot size and must include at least a minimum contiguous lawn area, that is free of limiting factors (location and type of water supply, soil type, depth to groundwater or impervious layer, slope, flooding potential and other limiting factors), sufficient for the construction of two standard soil treatment systems. Lots that would require use of holding tanks may not be approved.
(D) Information requirements. Developers must provide adequate information 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 U.S. Geological Survey maps or more accurate sources, showing limiting site characteristics;
(2) The surface water features required in M.S. Chapter 505 to be shown on plats, obtained from U.S. Geological Surveys 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) The location of regional floodplain areas from existing maps or data; and
(6)
A line or contour representing the ordinary high water level (OHW), the “toe” and the “top” of the bluffs, and the minimum building setback distances from the top of the bluff and the lake.
(E) Dedications. The developer shall provide, where required by the city, the fee transfer or easement dedication for natural drainage or ponding areas for management of stormwater and wetlands.
(F) Planned unit developments. Planned unit developments in the Shoreland Overlay District shall also be regulated by § 151.03.14 PUDs in Shoreland Areas.
