(a) Length and Bearing of the exterior boundaries of the proposed subdivision referenced to at least two corners established in the U.S. Public Land Survey and the total acreage encompassed thereby. The lengths of lines shall be given to the nearest 0.01 foot and bearings to the nearest one second of arc. The arc length, chord length, radius length, and bearing shall be given for all curved line.

(b) Location of Civil Division Boundary Lines and U.S. Public Land Survey system section and one-quarter section lines within the plat and within 100 feet of the exterior boundaries of the plat.

(c) Topographic Features including existing contours within the exterior boundaries of the plat and extending to the centerline of adjacent public streets at vertical contour intervals of preferably one-foot intervals but not more than two-foot intervals. Elevations shall be marked on such contours, referenced to a vertical datum approved by the town or County engineer. Any rock outcrops, slopes of 12 percent or greater, ridge lines, and hilltops shall be noted.

(d) Location and Elevation of Ordinary High Water Marks (OHWM) of all navigable creeks, streams, rivers, ponds, lakes, flowages, and drainage ditches within the exterior boundaries of the plat and within 100 feet therefrom. The OHWM elevation shall be referenced to a vertical datum approved by the town or County engineer. The status of navigability of these surface water features shall be indicated based upon a determination by the Wisconsin Department of Natural Resources.

(e) Shoreland Boundaries and boundaries of the one percent annual probability (100-year recurrence interval) flood and related floodplain regulatory stages, as determined by the Federal Emergency Management Agency. Where such data are not available, the elevation shall be determined by a professional engineer retained by the subdivider, and the sealed engineer’s report providing the required data shall be submitted with the plat for review and approval by the town or County Engineer. The contour line lying a vertical distance of two feet above the one percent annual probability flood shall also be shown.

(f) Boundaries of Primary and Secondary Environmental Corridors and isolated natural resource areas, as delineated and mapped by SEWRPC. The boundaries of wetlands shall also be shown. The wetland boundaries shall be shown as determined on the basis of a field survey made to identify, delineate, and map those boundaries; and the name of the person, agency, or firm identifying, delineating, and mapping the boundaries shall be provided together with the date of the field survey concerned.

(g) Location of Any Woodlands as mapped by SEWRPC and/or field surveyed, and existing vegetation to be retained or removed within the proposed subdivision.

(h) Location, Right-of-Way Width, and names of all existing and proposed streets, highways, alleys, or other public ways, bicycle and pedestrian/recreational ways, active and abandoned railroad rights-of-way, utility rights-of-way, access-control and vision corner clearance easements, deed restricted areas, conservation easements, and other easements within the exterior boundaries of the plat or immediately adjacent thereto.

(i) Type, Width, and Elevation of any existing street pavements within the exterior boundaries of the plat or immediately adjacent thereto, together with any legally established centerline elevations, all referenced to a vertical datum approved by the town or County engineer.

(j) Location and Names of any adjacent subdivisions, parks, cemeteries, public lands, and watercourses, including impoundments. The owners of record of abutting unplatted lands shall also be shown.

(k) Locations of All Existing structures, together with an identification of the type of structure, such as residence, garage, barn, or shed; the distances of such structures from existing and proposed property boundary lines, wells, drives, watercourses, drainage ditches, wetlands, wooded areas, railroad tracks, and other similar significant natural or manmade features; and existing property lines in the area adjacent to the exterior boundaries of the proposed plat and within 100 feet thereof. The proposed use of existing structures to be retained shall be noted. All wells within the exterior boundaries of the plat and within 100 feet of the exterior boundaries of the plat shall be shown.

(l) Location, Size, and Invert Elevation of any existing sanitary or storm sewers, culverts, and drain pipes; the location of manholes, catch basins, hydrants, electric and communication facilities, whether overhead or underground; and the location and size of any existing water and gas mains within the exterior boundaries of the plat or immediately adjacent thereto. If no sewers or water mains are located on or immediately adjacent to the subdivision, the nearest such sewers or water mains which might be extended to serve the subdivision shall be indicated by their direction and distance from the nearest exterior boundary of the plat, and by their size, and invert elevations. All elevations shall be referenced to a vertical datum approved by the town or County engineer.

(m) Location of Existing and Proposed POWTS (private onsite wastewater treatment systems) if public sanitary sewer service is not available.

(n) Location of Soil Boring and Percolation Tests within the exterior boundaries of the plat.]

(o) Existing and, if Applicable, Proposed Zoning on and adjacent to the proposed subdivision.

(p) Building or Setbacks Lines including those which are proposed to be more restrictive than the regulations of the zoning district in which the plat is located.

(q) Existing and Proposed Lot Lines, approximate dimensions and size of lots, the minimum lot area required by the zoning district in which the plat is located, together with proposed lot and block numbers. Lots and blocks shall be numbered consecutively.

(r) Location Approximate Dimensions, and Area of any sites to be reserved or dedicated for parks, playgrounds, drainageways, open space preservation, or other public use or which are to be used for multi-family housing, shopping centers, church sites, or other nonpublic uses not requiring lotting.

(s) Location, Approximate Dimensions, and Area of any proposed common areas or facilities.

(t) Approximate Radii of all curved lines within the exterior of the plat.

(u) Lake, River, and Stream Meander Lines proposed to be established if applicable.

(v) Any Proposed Lake and stream access, and the width of the proposed access, to be provided within the exterior boundaries of the plat.

(w) Any Proposed Lake, river, and stream improvement or relocation, and notice of application for approval by the Wisconsin Department of Natural Resources, when applicable.

(x) Additional Information requested by the County zoning administrator or staff, County zoning committee, or town board, plan commission, or staff. [Code § 14.04-3.]
