General. A preliminary plat shall be required for all subdivisions
and shall be based upon a survey by a land surveyor registered in
this state. A preliminary plat shall be prepared on paper of good
quality capable of clearly legible reproduction at a scale of not
more than 100 feet to the inch and shall show correctly on its face
the following information:
Location of proposed subdivision by: government lot, quarter-quarter
section, township, range, county, and state; and a location map showing
the relationship between the plat and its surrounding area and existing
streets.
The entire area contiguous to the proposed plat owned or controlled
by the subdivider shall be included on the preliminary plat even though
only a portion of said area is proposed for immediate development.
The subdivider may elect to submit a development plan in lieu of a
preliminary plat for that part of the land not to be included in the
final plat if the total contiguous area owned or controlled by the
subdivider is greater than 40 acres.
Exact length and bearing of the exterior boundaries of the proposed
subdivision referenced to a corner established in the United States
Public Land Survey and the total acreage encompassed thereby.
Contours at vertical intervals of not more than two feet where average
slope is less than 5% or four feet where slope is 5% or greater. Elevations
shall be marked on such contours based upon USGS data where available
and upon the best available data in all other cases.
Water elevation of adjoining lakes and streams at the date of the
survey and approximate high and low water elevations, based upon USGS
data where available and upon the best available data in all other
cases.
Location, right-of-way width, and names of all existing streets,
alleys, or other public ways, easements, and utility rights-of-way
and all section and quarter section lines within the exterior boundaries
of the plat or immediately adjacent thereto.
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, based
upon or established by the best available data.
Location, size, and invert elevation of any existing sanitary or
storm sewers, culverts, and drain pipes; the location of manholes,
catchbasins, hydrants, 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 sewers or water
mains are located on or immediately adjacent to the tract, the nearest
such sewers or water mains which might be extended to serve the tract,
shall be indicated by their direction and distance from the tract,
size, and invert elevations.
Locations of all existing property boundary lines, structures, drives,
streams, and watercourses, marshes, rock outcrops, wooded areas, and
other similar significant features within the tract being subdivided
or immediately adjacent thereto.
When requested by the Village, a draft of a protective covenant
whereby the subdivider proposes to regulate land use in the subdivision
and otherwise protect the proposed development.
Street plans and profiles. Where required, the subdivider shall provide
street profiles showing existing ground surface of the proposed center
line, right-of-way lines, and building setback lines, including extensions
for a reasonable distance beyond the limits of the proposed subdivision.
All elevations shall be based upon USGS data, and profiles shall meet
the approval of the Village Engineer.
Testing. The Village Engineer may require that borings and soundings
be made in specific areas to ascertain subsurface soil, rock, and
water conditions, including depth to bedrock and depth to groundwater
table.
Affidavit. 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 or she has fully
complied with the provisions of this chapter.
The development plan, as provided for in § 371-14, shall be submitted at a scale not more than 200 feet to one inch and shall show:
The subdivider shall cause to be set upon the final plat arrows indicating the direction of drainage flows for each property line not fronting on a street on all parcels, as will result from the grading of the site, the construction of the required public improvements, or which are existing drainage flows and will remain (see § 371-27). The arrows shall be accompanied on the plat with the following note:
"Arrows indicate the direction of drainage. Drainage patterns
shall be maintained by the lot owner unless written approval for modification
is obtained from the Village."
The certified survey map shall comply with the provisions of § 236.34, Wis. Stats. and § 371-16.
