A preliminary plat shall be required for all subdivisions, shall be based upon a survey by a professional land surveyor, shall comply in all respects with the requirements of Ch. 236, Wis. Stats., and shall comply with the design standards and improvement requirements set forth in Articles VII and VIII of this chapter, and the plat shall be prepared on tracing cloth, reproducible drafting film, or paper of good quality at a map scale of not more than 100 feet to the inch and shall show correctly on its face the following information:
A. 
Title or name under which the proposed subdivision is to be recorded. Such title shall not be the same as or similar to a previously approved and recorded plat in Waukesha County, unless it is an addition by the same owner to a previously recorded plat and is so stated on the plat.
B. 
Property location of the proposed subdivision by government lot, quarter section, township, range, county and state.
C. 
General location sketch showing the location of the subdivision within the U.S. Public Land Survey section oriented on the sheet in the same direction as the main drawing.
D. 
Date, graphic scale and North arrow.
E. 
Names and addresses of the owner, subdivider and land surveyor preparing the plat.
F. 
Entire area contiguous to the proposed plat owned or controlled by the subdivider and/or owner shall be included on the preliminary plat even though only a portion of said area is proposed for immediate development. The Plan Commission may waive this requirement where it is unnecessary to fulfill the purposes and intent of this chapter and severe hardship would result from strict application thereof.

All preliminary plats shall show the following:
A. 
Exact length and bearing of the exterior boundaries of the proposed subdivision referenced to a corner established in U.S. Public Land Survey and the total acreage encompassed thereby.
B. 
Existing and proposed contours at vertical intervals of not more than two feet where the slope of the ground surface is less than 10% and of not more than five feet where the slope of the ground surface is 10% or more. Elevations shall be marked on such contours based on National Geodetic Vertical Datum of 1929 (mean sea level).
C. 
Water elevations of adjoining lakes and streams at the date of the survey and approximate high and low water elevations, all referred to mean sea level (1929) datum.
D. 
Floodplain limits and the contour line lying a vertical distance of two feet above the elevation of the one-hundred-year recurrence interval flood or, where such data is not available, five feet above the elevation of the maximum flood of record.
E. 
Location, right-of-way width and names of all proposed and existing streets, alleys or other public ways, easements, railroad and utility rights-of-way and all section and quarter section lines within the exterior boundaries of the plat or immediately adjacent thereto.
F. 
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 center-line elevations, all to mean sea level (1929 datum).
G. 
Location and names of any adjacent subdivisions, parks and cemeteries, and owners of record of abutting unplatted lands.
H. 
Location, size and invert elevation of any existing sanitary or storm sewers, culverts and drainpipes, the location of manholes, catch basins, hydrants, and power and telephone poles, 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 sanitary or storm sewers or water mains are located on or immediately adjacent to the lands being platted, the nearest such sewers or water mains which might be extended to serve such lands shall be indicated by their direction and distance from the nearest exterior boundary of the plat and their size and invert elevations.
I. 
Locations of all existing property boundary lines, structures, drives, streams and watercourses, marshes, rock outcrops, wooded areas, railroad tracks, drainage easements, natural drainage areas, landfills and other similar significant natural or man-made features within the tract being subdivided or immediately adjacent thereto.
J. 
Approximate dimensions of all lots together with proposed lot and block numbers.
K. 
Location and approximate dimensions and size of any sites to be reserved or dedicated for parks, playgrounds, drainageways, or other public use or which are to be used for group housing, shopping centers, church sites, or other private uses not requiring platting.
L. 
Approximate radii of all curves.
M. 
Existing zoning on and adjacent to the proposed subdivision.
N. 
Any proposed lake and stream access with a small drawing clearly indicating the location of the proposed subdivision in relation to the access.
O. 
Any proposed lake and stream improvement or relocation.
P. 
Soil type, slope, and boundaries as shown on the detailed operational soil survey maps prepared by the U.S. Natural Resources Conservation Service.[1]

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
Q. 
Location of soil tests shall be shown, where required by this chapter and the Waukesha County Code of Ordinances for on-site sewage disposal systems to portray the character of the soil and depths of bedrock and groundwater from the natural undisturbed surface. The results of the test must be furnished along with the preliminary plat/certified survey map.
R. 
Delineations of natural resource areas, including the boundaries of primary/secondary environmental corridors and isolated natural resource areas as identified by the Southeastern Wisconsin Regional Planning Commission (SEWRPC) and the location and type of any rare or endangered species habitat.
S. 
Historical, cultural and archaeological features, with a brief description of the historic character of buildings, structures, ruins and burial sites.
T. 
Locations of all 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.
U. 
Surveyor's certificate signed, dated and sealed, and revision dates on all sheets.
V. 
Sheet numbers.
W. 
Additional information as requested by the Plan Commission or governing body to verify ownership, clarify questions raised during the approval procedure, address concerns raised by neighbors or members of the Plan Commission or governmental body and any other information the Plan Commission or governing body deems necessary to reach a decision on the preliminary plat. Failure to provide the requested additional information may be grounds for denial of the preliminary plat.
The Plan Commission, upon recommendation of the Municipal Engineer, may require that the subdivider provide street plans and profiles showing existing ground surface, proposed and established street grades, storm sewer plans and profiles showing the location, grades, sizes, cross sections, elevations and materials of required facilities, where applicable, including extensions for a reasonable distance beyond the limits of the proposed subdivision when requested. All elevations shall be based upon mean sea level (1929) datum, and plans and profiles shall meet the approval of the Municipal Engineer.
The Plan Commission, upon recommendation of the Municipal Engineer, may require that borings and soundings be made in specified areas to ascertain subsurface soil, rock and water conditions, including depth to bedrock and depth to groundwater table. Where the subdivision will not be served by public sanitary sewer service, the provisions of the Wisconsin Administrative Code shall be complied with and the appropriate data submitted with the preliminary plat.
The Plan Commission, upon determining from a review of the preliminary plat by the Municipal Engineer that the soil, slope, vegetation, and drainage characteristics of the site are such as to require substantial cutting, clearing, grading, and other earthmoving operations in the development of the subdivision or otherwise entail a severe erosion hazard, may require the subdivider to provide soil erosion and sedimentation control plans and specifications. Such plans shall generally follow the guidelines and standards set forth in any and all ordinances, rules, regulations and publications adopted by separate resolution by the Town Board.
The surveyor preparing the preliminary plat shall certify on the face of the plat that it is a correct representation of all existing land divisions and features and that he has fully complied with the provisions of this chapter.
