been given to the Village. Inspection fees shall be required as specified
in Article 11 of this chapter.
No building, zoning, or sanitary permits shall be issued for

of this chapter have been met.
The following plans and accompanying construction specifications
shall 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

The subdivider shall cause all grading, excavations, open cuts,

seeded, sodded, or otherwise protected that erosion, siltation, sedimentation,
and washing are prevented, in accordance with the plans and specifications
approved by the Village Plan Commission, upon recommendation of 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.
The subdivider, prior to commencing any work within the subdivision,
shall notify the Village Clerk to make arrangements with the Village
Engineer to provide for adequate inspection. The Village Engineer
shall inspect and approve all completed work prior to approval of
the final plat or, where a development agreement has been entered
into with the Village, prior to the release of the sureties.
