Character of land. Land to be subdivided shall be of
such character that it can be used safely for building purposes without danger
to health or peril from fire, flood or other menace.
Conformity to Official Map and Comprehensive Plan. Subdivisions
shall conform to the streets and parks shown on the Official Map, as may be
adopted, and shall be properly related to the Comprehensive Plan, if any,
as it is developed and adopted by the Village Board.
Subdivisions shall be so designed as to provide a street
pattern which shall be based upon a local, residential or minor street pattern
connected to a residential collector street system.
The arrangement of streets in new subdivisions shall
make provision for the continuation of existing streets in adjoining areas,
or their proper protection where adjoining land is not subdivided, at the
same or greater width insofar as such may be deemed necessary for public requirements.
When a subdivision abuts or contains an existing or proposed
major arterial street, the Village Board may require marginal access streets,
reverse frontage with screen planting contained in a nonaccess reservation
along the rear property line, deep lots with rear service alleys or such other
treatment as may be necessary for adequate protection of residential properties
and to afford separation of through and local traffic.
The grades of streets shall be in accordance with specifications
established by the Village Engineer, and such grades as submitted on subdivision
plats shall be approved by him or her prior to final approval by the Village
Board.
All proposed subdivisions shall be designed to provide
access to adjacent properties. When a proposed subdivision abuts an existing
subdivision, the subdivider shall make every attempt to design the street
system of the proposed subdivision to connect with dead-end or "stub" streets
of the existing subdivision.
Unless there is the expectation of extending the street
through to the adjoining property, a cul-de-sac street should never be brought
to the property boundary line, but should be placed so that the lots can back
on the property line of the subdivision.
If a dead-end is of a temporary nature, a similar turnaround
shall be provided and provisions made for future extension of the street through
to adjacent property and reversion of the excess right-of-way to the adjoining
properties.
Local residential streets and residential collector streets
shall not intersect with arterial streets less than 1,000 feet apart, measured
from center line to center line.
No street shall have a name which will duplicate or so
nearly duplicate as to be confused with the names of existing streets. The
continuation of an existing street shall have the same name.
Proposed street names shall be cleared with the County
Highway Department to avoid duplication or use of similarly sounding or spelled
names. Street names shall also be cleared with the Village Board. Streets
that are extensions of or in alignment with existing streets shall bear the
names of existing streets. House numbers should be shown following standard
practice of house numbering. A copy of the final map shall be filed with the
local post office and with the fire-fighting organization servicing the area.
The minimum radius of horizontal curves, minimum length
of vertical curves and minimum length of tangents between reverse curves shall
be in accordance with specifications established by the Village Engineer and
shall be approved by him or her prior to final approval of the subdivision
plat by the Village Board.
In general, street lines within a block, deflecting from
each other at any one point by more than 10º, shall be connected with
a curve, the radius of which for the center line of the street shall not be
less than 400 feet on major streets, 200 feet on collector streets and 100
feet on minor streets.
When a subdivision borders on or contains a railroad
right-of-way or limited access highway right-of-way, the Village Board may
require a street approximately parallel to and on each side of the right-of-way,
at a distance suitable for the appropriate use of the intervening land (as
for park purposes in residential districts or for commercial or industrial
purposes in appropriate districts). Such distances shall also be determined
with due regard for the requirements of approach grades and future grade separations.
The lot size, width, depth, shape, orientation and the
minimum building setback lines shall be appropriate for the location of the
subdivision and for the type of development and use contemplated.
All lots shown on the subdivision plat must conform to the minimum requirements of Chapter 160, Zoning, of this Code as to area, dimensions, setbacks, width and all other requirements for the zone in which the subdivision is located.
Where extra width has been dedicated for widening of
existing streets, lots shall begin at such extra line and all setbacks shall
be measured from that line.
Where there is a question as to the suitability of a
lot or lots for their intended use due to factors such as rock formations,
flood conditions or similar circumstances, the Village Board may, after adequate
investigation, require modification of those lots.
Block length and width or acreage within bounding roads shall be such as to accommodate the size of lot required in the area by Chapter 160, Zoning, and to provide for convenient access, circulation control and safety of street traffic.
Blocks intended for commercial or industrial use shall
be designed specifically for those purposes with adequate space set aside
for off-street parking and delivery facilities.
The lot arrangement shall be such that, in constructing a building in compliance with Chapter 160, Zoning, there will be no foreseeable difficulties for reasons of topography or other natural conditions. Lots should be not of a depth as to encourage the later creation of a second building lot at the front or rear.
Driveway access and grades shall conform to specifications
as established by the Village Engineer and such other specifications as are
on file in the Village Clerk's office. Driveway grades between the pavement
and setback line shall not exceed 10%.
Where a tract is subdivided into lots substantially larger
than the minimum size required in the applicable zoning district, the Village
Board may require that streets and lots be laid out so as to permit future
resubdivision in accordance with the requirements contained in these regulations.
Easements. An easement shall be provided for all natural
drainage ways and all utility lines when such utility line or lines do not
fall within a dedicated right-of-way. All easements shall be plotted on the
preliminary plat and subdivision plat. A clause shall be inserted in the deed
of each lot affected by an easement indicating that the easement exists and
its purpose. Except as further required in this section, easements shall have
a minimum width of 12 feet. Where a subdivision is traversed by a drainageway,
channel or stream, a drainageway easement conforming substantially with the
lines of such watercourse shall be provided. The easement shall be 20 feet
wide or such additional width as will be adequate to preserve natural drainage
and provide sufficient width for maintenance. Where it is found that additional
easement width is needed, such width shall be determined by the Village Board
in consultation with the Village Engineer. All utility lines which are primarily
intended to provide service to the lots within the subdivision shall be installed
underground at a depth and at such location as will minimize risk of interruption
of services. A five-foot easement running parallel with and contiguous to
all street and highway rights-of-way shall be provided to the Village, granting
the Village the right to protect, plant, prune, spray, remove, control, regulate
and improve shrubbery and shade trees thereon.
The developer shall provide a liberal and functional
landscaping scheme for the entire subdivision. Each lot shall be provided
with a minimum of two trees, which shall be in addition to the street shade
trees. This requirement may be waived by the Village Board in wooded areas
where the subdivider intends to maintain existing trees.
If the approved plat specifically permits it, individual
homeowners may, by written agreement with the subdivider and builder, seed
and landscape their yards independently.
When a proposed subdivision borders upon an existing
commercial or industrial establishment, or any other use which, in the opinion
of the Village Board, may be visually detrimental to the tranquility of the
future residents of the subdivision, the Village Board may require a landscape
screen to buffer the subdivision from the visually noncompatible use.
Topsoil moved during the course of construction shall
be redistributed so as to cover all areas of the subdivision and shall be
stabilized by seeding or planting. At no time shall topsoil be removed from
the site without written permission from the Village Board.
To the fullest extent feasible, all existing trees and
shrubbery shall be conserved by the subdivider. Special consideration shall
be given to the arrangement and ultimate improvement or development of the
lots to this end. Precautions shall also be taken to protect existing trees
and shrubbery during the process of grading the lots and roads. Where there
is a question as to the desirability of removing a group of trees, which serve
to add interest and variety to the proposed subdivision, in order to allow
for use of the land for a lot or lots, the Village Board may, after proper
investigation, require modification of those lots. Where any land other than
that included in public rights-of-way is to be dedicated to the public use,
the developer shall not remove any trees from the site without written permission
from the Village Board.
Where a subdivision is traversed by a natural lake, pond
or stream, the boundaries or alignment of that watercourse shall be preserved
unless, in the opinion of the Village Board, a change or realignment will
enhance the development and beauty of the subdivision or the utilization of
such features by the future residents of the subdivision. All proposed changes
in watercourse alignment shall be in accordance with the Environmental Conservation
Law.
The subdivider shall not be permitted to leave any hills
or mounds of dirt around the tract. All surfaces shall be restored within
six months of the time of the completion of the section of the subdivision.
Mapping. If any portion of the land within the subdivision is subject to inundation or flood hazard by stormwater, such fact and portion shall be clearly indicated on the preliminary plat and final plat and the prominent note on each sheet of such map whereon any such portion shall be shown. As part of the applications, the applicant shall demonstrate the provisions of Chapter 75 shall be fully complied with.
Use. Land subject to flooding and land deemed by the
Village Board to be otherwise uninhabitable shall not be platted for residential
occupancy nor for such other uses as may increase danger to health, life or
property or aggravate the flood hazard.
The subdivider may be required by the Village Board to
carry away by pipe or open ditch any spring- or surface water that may exist
either previous to or as a result of the subdivision. Such drainage facilities
shall be located in the street right-of-way, where feasible, or in peripheral
unobstructed easements of appropriate width.
A culvert 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 the subdivision. The Village Engineer shall approve the design and size of the facility based on anticipated runoff from a ten-year storm under conditions of total potential development permitted by Chapter 160, Zoning, in the watershed.
The subdivider's engineer shall submit a written study
showing the effect of the proposed subdivision on the existing downstream
drainage facilities outside the area of the subdivision; this study shall
be reviewed by the Village Engineer. Where it is anticipated that the additional
runoff incident to the development of the subdivision will overload an existing
downstream drainage facility during a five-year storm, the Village Board shall
not approve the subdivision until provision has been made for the improvement
of the condition.
Land shall be reserved for a park, a playground, open
space and/or other recreational purposes in locations designated on the Comprehensive
Plan, if any, or elsewhere where the Village Board deems that such reservations
would be appropriate. For a subdivision, each reservation shall equal 10%
of the total land area within the subdivision, but in any major subdivision
the reservation shall be at least one acre. The area to be preserved shall
possess the suitable topography, general character and adequate road access
necessary for its recreational purposes.
Where the Village Board requires land to be set aside
for parks, playgrounds and/or other recreational purposes, the Village Board
may require that the site be graded, loamed and seeded and may require it
to be fenced, and existing trees shall be preserved, where feasible.
When area for a park, a playground, recreational purposes
or open space is required on the subdivision plat, the approval of that subdivision
plat shall not constitute an acceptance by the Village of such an area.
