(A) Existing conditions. Existing conditions including:
(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 licensed 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 ground water 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. Proposed design including:
(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 on-site 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 to subdivide. 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.
