A.
A preliminary plat shall be required for all subdivisions
and shall be based upon a survey by a registered land surveyor, 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:
(1)
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, unless it is an addition
to a previously recorded plat and is so stated on the plat.
(2)
Property location of the proposed subdivision by government
lot, quarter-section, township, range, county and state.
(3)
General location sketch showing the location of the
subdivision within the United States Public Land Survey section.
(4)
Date, graphic scale and North arrow.
(5)
Names and addresses of the owner, subdivider and land
surveyor preparing the plat.
B.
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 City Plan Commission may waive this requirement where
it is unnecessary to fulfill the purpose 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
the United States 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 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 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 and other similar significant natural
or man-made features within the tract being subdivided or immediately
adjacent thereto.
J.
Location, width and names of all proposed streets
and public rights-of-way, such as alleys and easements.
K.
Approximate dimensions of all lots together with proposed
lot and block numbers.
L.
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 lotting.
M.
Approximate radii of all curves.
N.
Existing zoning on and adjacent to the proposed subdivision.
O.
Any proposed lake and stream access with a small drawing
clearly indicating the location of the proposed subdivision in relation
to the access.
P.
Any proposed lake and stream improvement or relocation.
Q.
Soil type, slope, and boundaries as shown on the detailed
operational soil survey maps prepared by the United States Department
of Agriculture, Natural Resources Conservation Service.
R.
Location of soil boring tests, where required by Ch.
Comm 85, Wis. Admin. Code, made to a depth of six feet, unless bedrock
is at a lesser depth. The number of such tests shall be adequate to
portray the character of the soil and the depths of bedrock and groundwater
from the natural undisturbed surface. To accomplish this purpose,
a minimum of one test per three acres shall be made initially. The
results of such tests shall be submitted along with the preliminary
plat.
S.
Location of soil percolation tests where required
by Ch. Comm 85, Wis. Admin. Code, conducted in accordance with said
chapter, taken at the location and depth in which soil absorption
waste disposal systems are to be installed. The number of such tests
initially made shall not be fewer than one test per three acres or
one test per lot, whichever is greater. The results of such tests
shall be submitted along with the preliminary plat.
The City Plan Commission, upon recommendation
of the City Engineer, may require that the subdivider provide street
plans and profiles showing existing ground surface and proposed and
established street grades, 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 City Engineer.
The City Plan Commission, upon recommendation
of the City 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 Ch. Comm 85, Wis. Admin. Code, shall be complied with
and the appropriate data submitted with the preliminary plat.
The City Engineer, upon determining from a review
of the preliminary plat that the soil, slope, vegetation, and drainage
characteristics of the site are such as to require substantial cutting,
clearing, grading, and other earth-moving 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 the publication Soil and Water Conservation
District Technical Guide, prepared by the United States Department
of Agriculture, Natural Resources Conservation Service, as amended.
The City Plan Commission may require submission
of a draft of protective covenants whereby the subdivider intends
to regulate land use in the proposed subdivision and otherwise protect
the proposed development. The City Attorney shall review all covenants
and shall approve covenants as to form.
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.
