(3) On -site sewage treatment systems shall be set back from the ordinary high-water level in accordance with the setbacks contained in section 34-2022(a). `-- (4) All proposed sites for individual sewage treatment systems shall be evaluated in accordance with the criteria in subsections (b)(1) through (4) of this section. It shall be the responsibility of the applicant to provide sufficient soil borings and percolation tests from on -site field investigations. Evaluation criteria are as follows: a. Depth to the highest known or calculated groundwater table or bedrock. b. Soil conditions, properties, and permeability. c. Slope. d. The existence of lowlands, local surface depressions, and rock outcrops. (5) Nonconforming sewage treatment systems shall be regulated and upgraded in accordance with section 30- 1986(3). (Code 1982, § 904.08(8); Ord. No. 15-06, § 33 2-17-2015) Secs. 30-2029--30-2040. - Reserved. Subdivision V. - Restrictions and Requirements Sec. 30-2041. - Subdivisions and platting. (a) Land suitability. Each lot created through subdivision, including planned unit developments authorized under section 30-2042, shall 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 owl 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) Conformance with subdivision controls. Subdivisions shall 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 sections 30- 2022 and 30-2028 can be provided for every lot. Each lot shall meet the minimum lot size and dimensional requirements of section 30-2021, 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 shall not be approved. (c) Information requirements. Sufficient information shall be submitted by the applicant according to section 30-303 for the city to make a determination of land suitability. In addition, the following information shall be provided in shoreland districts: (1) 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; (2) 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; (3) Location of 100-year floodplain areas and floodway districts from existing adopted maps or data; and (4) A line or contour representing the ordinary high-water level as established by the state department of natural resources, the toe and the top of bluffs, and the minimum building setback distances from the top of the bluff �.- and the lake or stream. �(d ) Dedications.ltlhen a land or easement dedication is a eor�_�. iyis�'on aprs�1-h-ap-�t�oi easements over natural drainage or ponding areas for management of stormwater and significant wetlands.
