[Amended 4-12-2021 by Ord. No. 5-21]
No construction or installation of improvements shall commence in a proposed subdivision until the preliminary plat has been approved by the Village Plan Commission and the Village Engineer has given written authorization. No construction or installation of improvements shall commence in a minor land division until the certified survey map has been approved by the Village Board and the Village Engineer has given written authorization. Inspection fees shall be required as specified in Article X of this chapter.
No building, zoning, or sanitary permits shall be issued for erection of a structure on any lot not of record until all the requirements of this chapter have been met.
The following plans and accompanying construction specifications may be required by the Village Plan Commission and reviewed by the Village Engineer before authorization of construction or installation of improvements:
A. 
Street plans and profiles showing existing and proposed grades, elevations and cross sections of required improvements.
B. 
Sanitary sewer plans and profiles showing the locations, grades, sizes, elevations and materials of required facilities.
C. 
Storm sewer plans and profiles showing the locations, grades, sizes, cross sections, elevations and materials of required facilities.
D. 
Water main plans and profiles showing the locations, sizes, elevations and materials of required facilities.
E. 
Erosion and sedimentation control plans showing those structures required to retard the rate of runoff water and those grading and excavating practices that will prevent erosion and sedimentation. The time span that soil will be exposed and plans to protect existing vegetation (fences, tree wells, etc.) shall be prepared, and such plans shall generally follow the guidelines and standards set forth in the publication "United States Soil Conservation Service Technical Guide," adopted by the Ozaukee County Land Conservation Committee, as amended.
F. 
Planting plans showing the location, age, caliper, and species of any required grasses, vines, shrubs, and trees.
G. 
Grading plan with 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). The master site grading plan shall also show the street grade in the front of each lot and the top of foundation, finished garage slab grade and finished yard grade. If required by the Village Plan Commission or Village Engineer, the master site grading plan shall be revised after curb and gutter are installed.
[Amended 7-10-1995 by Ord. No. 14-95]
H. 
Additional special plans or information as required.
The subdivider shall cause all grading, excavations, open cuts, side slopes, and other land surface disturbances to be so mulched, seeded, sodded, or otherwise protected that erosion, siltation, sedimentation, and washing are prevented, in accordance with the plans and specifications approved by the Village Engineer. In addition:
A. 
All erosion control plans shall incorporate best management practices to reduce soil loss during construction to 10% of the gross soil loss as estimated by the universal soil loss equation.
B. 
Sod shall be laid in strips at those intervals necessary to prevent erosion and at right angles to the direction of drainage.
C. 
Temporary vegetation and mulching shall be used to protect critical areas, and permanent vegetation shall be installed as soon as practical.
D. 
Construction at any given time shall be confined to the smallest practical area and for the shortest practical period of time.
E. 
Sediment basins shall be installed and maintained at all drainageways to trap, remove, and prevent sediment and debris from being washed outside the area being developed.
The subdivider shall make every effort to protect and retain all existing trees, shrubbery, vines, and grasses not actually lying in public roadways, drainageways, building foundation sites, private driveways, soil absorption waste disposal areas, paths, and trails. Such trees are to be protected and preserved during construction in accordance with sound conservation practices, including the preservation of trees by well islands or retaining walls whenever abutting grades are altered.
