(A) Existing conditions.
(1) Boundary lines with lengths and bearings drawn to exact scale of no less than one inch equals 100 feet taken from a boundary survey by a registered land surveyor with the legal description of the property, total acreage, name of the fee owner, developer, and surveyor. North arrow and scale;
(2) Topography consisting of two-foot contour intervals, or, at the discretion of the Planning Commission during the sketch plan review, ten-foot contour intervals taken from USGS mapping with additional field determined spot elevations added to define drainage ways, 100-year floodplains, wetlands, slopes, and the ordinary high water mark. Near-shore aquatic conditions, including depths, types of bottom, sediments, and aquatic vegetation;
(3) Tree cover limits, specimen tree locations;
(4) Soils as determined by hand borings on a random basis, to determine depth to groundwater at lower elevations and suitability for sewage treatment systems. At least one boring for each unit unless waived by the Planning Commission;
(5) Location of adjoining streets, wetlands, structures, and property lines within 200 feet of subject parcel, including acreage of any property owned by the developer not included in the preliminary plat;
(6) Significant historical sites;
(7) Significant wildlife habitat areas;
(8) Endangered, threatened, rare, or critical species, both flora and fauna;
(9) Date of boundary survey, topography, and proposed plat;
(10) Layout of existing streets, walkways, driveways, blocks, lots, and structures drawn to the same scale;
(11) Locations of existing wells and sewage treatment systems;
(12) Location by section, town, and range with small scale sketch showing location within the city; and
(13) The existing zoning classification and the zoning classification of adjacent parcels.
(B) Proposed design.
(1) Layout of proposed streets, walkways, driveways, blocks, lots, and buildings if known, drawn to same scale as existing data;
(2) Dimensions scaled to nearest five feet of all lot lines, street widths, easement widths, and lakeshore lengths;
(3) Buildable areas of proposed lots;
(4) Structure setback lines from streets, lot lines, and ordinary high water mark and a designation of the buildable area on the parcel;
(5) Proposed green space with area shown;
(6) Proposed public dedication areas other than streets or walkways with the area shown;
(7) Proposed city sewer or water system connections and extensions, existing and proposed, with grades shown;
(8) Potential locations and estimated depth to water table for all proposed onsite sewage disposal systems, two per lot;
(9) Information regarding adequacy of domestic water supply;
(10) Proposed storm drainage system and erosion control, both during and after construction activities;
(11) Proposed street standards and profiles;
(12) Potential principal structure and accessory structure locations and elevations;
(13) Extent of anticipated vegetation and topographic alterations;
(14) Proposed covenants;
(15) Name of subdivision and proposed street names, which shall not duplicate or be alike another plat previously recorded; and
(16) Stages of development proposed.
(C) Authority. Evidence of authority to subdivide the parcel consisting of fee ownership or written concurrence of fee owners.
(D) Cost/benefit analysis. An analysis of the ongoing cost to the city to provide services and maintenance to the development shall be prepared using a form provided by the city. This cost shall be compared on the same form to the estimated increased valuation of the property and the corresponding tax revenue. The development shall not be approved if public subsidy is required for ongoing services and maintenance.
