In considering applications for subdivision of land, the Planning Board shall be guided by the standards set forth hereinafter. Said standards shall be considered to be minimum requirements and shall be waived by the Board only under circumstances set forth in Article
VI herein.
All names on the preliminary layout or final subdivision plat
shall be approved by the Planning Commission. In general, streets
shall have names and not numbers or letters. Proposed street names
shall be substantially different so as not to be confused in sound
or spelling with present names, except that streets that join or are
in alignment with streets or an abutting or neighboring property shall
bear the same name. Generally, no street should change direction by
more than 90° without a change in street name.
Adequate storm drainage systems shall be required in all new
subdivisions.
A. Removal of spring and surface water. Any spring or surface water
that may exist either previous to or as a result of the subdivision
shall be carried away by pipe or open ditch. Such drainage facilities
shall be located in the street right-of-way where feasible or in permanent
easements of appropriate width.
B. Drainage structure to accommodate upstream area. A culvert, ditch,
storm sewer, catch basin, inlet or other drainage facility shall,
in each case, be large enough to accommodate potential runoff from
its entire upstream drainage area, whether inside or outside of the
subdivision. The Village Engineer shall approve the design and size
of facility based on anticipated runoff from a twenty-five-year, six-hour
storm from current upstream conditions.
C. Responsibility for drainage downstream. The subdivider's engineer
shall also study the effect of each subdivision on existing downstream
drainage facilities outside the area of the subdivision, and this
study shall be reviewed by the Village Engineer. When it is anticipated
that the additional runoff incidental to the development of the subdivision
will overload an existing downstream drainage facility during a twenty-five-year,
six-hour storm, the Planning Board shall notify the Village Board
of such potential condition. In such case, the Planning Board shall
not approve the subdivision until provisions have been made for the
improvement of such condition.
D. Land subject to flooding. Land subject to flooding or land deemed
by the Planning Board to be uninhabitable shall not be platted for
residential occupancy, nor for such other use as may increase danger
to health, life or property or aggravate the flood hazard, but such
land within the plat shall be set aside for such uses as shall not
be endangered by periodic or occasional inundation or improved in
a manner satisfactory to the Planning Board to remedy said hazardous
conditions. All subdividers shall present an individual lot drainage
for each lot in their proposed subdivision. Such plan shall be used
in the grading of lots before a certificate of occupancy is granted.
No roof leaders or footing drains which carry stormwater will be permitted
to use sanitary sewer nor a so-called dry well in an area where dominant
soil is hardpan but shall be adequately disposed of upon the ground
surface.
