A.Â
Considerations. In considering applications for subdivision
of land and/or development, the Board shall be guided by the standards set
forth herein. Said standards shall be deemed to be minimum requirements for
the convenience, health, safety and welfare of the Village.
B.Â
Character of land. Land to be subdivided and/or developed
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. Land subject
to such hazards shall not be subdivided nor developed for residential purposes
nor for such other uses as may increase danger to health, life or property
or aggravate a flood hazard, but such land may be set aside for such uses
as shall not involve such danger nor produce unsatisfactory living conditions.
C.Â
Conformance to Comprehensive Plan and Official Map. Subdivisions
and/or developments shall conform to the Official Map and shall be properly
related to the proposals shown on the Comprehensive Plan. The plat shall include
all streets, shown on the said plan and map, which are within the site and
such other streets as the Board may require.
D.Â
Frontage on improved street. The area proposed to be
subdivided and/or developed shall have frontage on and direct access to a
street duly placed on the Official Map and, if such street is private, it
shall be improved to the satisfaction of the Board or there shall be a bond
held by the Village covering such improvement.
E.Â
Preservation of natural cover. Land to be subdivided
and/or developed shall be laid out and improved in reasonable conformity to
existing topography, in order to minimize grading, cut and fill and to retain,
insofar as possible, the natural contours, limit stormwater runoff and conserve
the natural cover and soil. No topsoil, sand or gravel shall be removed from
any lots shown on any subdivision plat except for the purpose of improving
such lots and for the laying out of streets shown thereon. Topsoil so removed
shall be restored to a depth of six inches and properly seeded and fertilized
on the areas of such lots not occupied by buildings or structures. No excess
topsoil so removed shall be disposed of outside of the boundaries of the Village
except upon the approval of the Board of Trustees of the Village.
F.Â
Preservation of existing natural features. Existing natural features that enhance the attractiveness of the site and which would add value to residential or other development or to the Village as a whole, such as trees, watercourses, ponds and similar irreplaceable assets, shall be preserved insofar as possible by harmonious design of the subdivision. The Board may make reasonable modifications in standards for layout of streets to accomplish such purposes as well as the objectives noted in Subsection E.
A.Â
General. The arrangement, character, extent, width, grade
and location of all streets shall conform to the Comprehensive Plan and Official
Map and shall be considered in their relation to existing and planned streets,
to existing topography and natural features, to public convenience and safety
and in their appropriate relation to the proposed uses of the land to be served
by such streets.
B.Â
Relation to topography. Street layouts and grades shall
be related appropriately to the existing topography, and streets shall be
arranged to obtain as many as possible of the building sites at or above the
grades of the streets. Steep grades shall be avoided, as well as combinations
of steep grades and curves.
C.Â
Arrangement. Where proposed streets are not shown on
the Comprehensive Plan or Official Map, such streets shall be of sufficient
width, suitably located and adequately constructed to accommodate the prospective
traffic and to facilitate drainage and to afford access for fire-fighting,
snow removal and road maintenance equipment. Such streets shall be coordinated
so as to compose a convenient system and to cause no undue hardship to adjoining
properties.
D.Â
Arrangements. The arrangement of streets shall provide
for the continuation of principal streets between adjacent properties when
such continuation is necessary for convenient movement of traffic, effective
fire protection or efficient provision of utilities and also where such continuation
is in accordance with the Comprehensive Plan. If the adjacent property is
undeveloped and the street must be a dead-end street temporarily, the right-of-way
shall be extended to the property line. A temporary circular turnaround shall
be provided on all temporary dead-end streets, with the notation on the plat
that land outside the normal street right-of-way shall revert to abuttors
whenever the street is continued.
E.Â
Intersections.
(1)Â
Street jogs with center-line offsets of less than 125
feet shall not be permitted except with the approval of the Board.
(2)Â
Intersections of streets shall be at angles as close
to 90° as possible. Toward this end, an oblique street should be curved
approaching an intersection and should be approximately at right angles for
at least 100 feet therefrom. Where three or more streets intersect, a turning
circle or other special treatment may be required by the Board. Wherever two
streets intersect at an angle smaller than 75°, the right-of-way returns
and the relation of the gutter grades shall be given special treatment, as
determined by the Board, and islands to channelize traffic may be required.
(3)Â
Intersections of major streets by other streets shall
be at least 800 feet apart, if possible. Cross (four-cornered) street intersections
shall be avoided insofar as possible, except as shown on the Comprehensive
Plan or at other important traffic intersections. A distance at least equal
to the minimum required lot depth plus 25 feet shall be maintained between
center lines of offset intersecting streets. Grades shall be limited to no
more than 2% within 50 feet of an intersection.
F.Â
Treatment along major arterial streets. Where a subdivision
abuts or contains an existing or proposed major arterial street, the 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.
G.Â
Provision for future resubdivision. Where a tract is
subdivided into lots substantially larger than the minimum size required by
the zoning, the 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.
H.Â
Dead-end streets.
(1)Â
Where a street does not extend to the boundary of the subdivision and its continuation is not required by the Board for access to adjoining property, its terminus shall normally not be nearer to such boundary than 100 feet or the minimum lot depth prescribed by Chapter 195, Zoning, whichever is greater. However, the Board shall require the reservation of a twenty-foot-wide easement to accommodate drainage facilities, pedestrian traffic or utilities.
(2)Â
For greater convenience to traffic and more effective
police and fire protection, permanent dead-end streets shall be limited in
length to 900 feet and shall be provided at the closed end with a turnaround
having an outside roadway diameter of at least 80 feet and a street property
line diameter of at least 100 feet. In zoning districts, however, which permit
lots of less than one acre, the minimum outside roadway diameter shall be
increased to 100 feet and the diameter at the property line shall be increased
to 120 feet. Where it is impossible to subdivide a property except by a dead-end
road which is longer than 900 feet, the Board may permit a greater length,
provided that a divided roadway with center mall is constructed in a seventy-foot
right-of-way (or greater width, if required) in such a manner that either
side of the roadway could be used, in emergencies, for two-way traffic.
I.Â
Design standards for streets. Streets shall meet the
design standards set forth below. In cases where street classification is
not shown on the Comprehensive Plan or Official Map, the Board shall determine
the type of each street. Standards do not cover major streets which would
be built by the state or county.
(2)Â
Grades.
(b)Â
Gradients shall be used to facilitate surface drainage
to proper natural or artificial outlets.
(c)Â
Changes in grade. All changes in street grades shall
be connected by vertical curves of sufficient radius to provide a smooth transition
and proper sight distance, as approved by the Board.
(3)Â
Tangents. A tangent at least 100 feet in length shall
be introduced between reverse curves on all streets, except where a greater
length is required by the Board.
(4)Â
Curves. When the alignment of the street changes more
than 10°, the tangents shall be connected by a curve with a radius of
not less than 200 feet, unless a greater radius is required by the Board to
ensure a proper sight distance.
J.Â
Reserve strips. Reserve strips controlling access to
streets shall be prohibited except where their control is placed in the Village
under conditions approved by the Board.
K.Â
Property lines at intersections. Property lines at intersections
shall be established in such a manner as to place within the street right-of-way
the triangular area which is formed by the street lines extended and a straight
line adjoining points on said street lines 30 feet distant from their point
of intersection.
L.Â
Street names. All streets shall be named, and such names
shall be approved by the Board. Names shall be sufficiently different in sound
and in spelling from other street names in the Village or adjoining municipalities
so as not to cause confusion. A street which is a continuation of an existing
street shall bear the same name. In general, street names shall conform to
the following classifications:
A.Â
Utilities. Easements across lots or centered on rear
or side lot lines shall be provided for utilities where necessary and shall
be at least 20 feet wide.
B.Â
Drainageway. Where a subdivision is traversed by a watercourse,
channel or drainageway, as defined herein, there shall be provided a stormwater
easement or drainage right-of-way conforming substantially to the lines of
such watercourse and such further width or construction, or both, as will
be adequate for the purpose. The Board may require parallel streets or parkways
in connection with such drainageway.
A.Â
Length, width and shape. The length, width and shape
of a block shall be determined with due regard to:
(1)Â
Provision of adequate building sites suitable to the
special needs of the type of use contemplated.
(2)Â
Zoning requirements as to lot sizes and dimensions.
(3)Â
Needs for convenient access, circulation, control and
safety of street traffic.
(4)Â
Limitations and opportunities of topography and the objectives
of these regulations.
B.Â
Dimensions. Block dimensions shall be at least twice
the minimum lot depth and generally not more than 1,200 feet.
C.Â
Crosswalk. In long blocks the Board may require the establishment
of easements or public ways through the block to accommodate utilities, drainage
facilities or pedestrian access to community facilities.
A.Â
General. The lot size, width, depth, shape and 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.
B.Â
Dimensions and corner lots. Lot area and dimensions shall conform to the requirements of Chapter 195, Zoning, and Health Department regulations. Corner lots for residential use shall have extra width to permit compliance with the front yard setback from both streets. Where lots are more than double the minimum area required by Chapter 195, Zoning, the Board may require that such lots shall be of such dimensions and arrangement as will allow further subdivision and the opening of future streets where necessary to serve potential lots, all in compliance with Chapter 195, Zoning, and these regulations. Generally the depth of a lot shall not exceed 21/2 times the width.
C.Â
Arrangement and access.
(1)Â
The lot arrangement shall be such that there will be
no foreseeable difficulty, for reasons of topography or other conditions,
in obtaining building permits to build on all lots in compliance with applicable
regulations and in providing, by means of a street approved by the Board and
upon which each lot fronts, safe driveway access to buildings on such lots
from an improved street duly placed on the Official Map.
(2)Â
Access across a watercourse. Where a watercourse separates
the buildable area of a lot from the street by which it has access, provisions
shall be made for installation of a culvert or other structure of design approved
by the Engineer.
D.Â
Lot lines and setbacks. Side lot lines shall be substantially
at right angles to straight streets and radial to curved street lines. Lot
lines shall coincide with municipal boundary lines rather than cross them.
Where extra width has been dedicated for widening an existing street, lots
shall begin at such extra width line, and lot dimensions and setbacks shall
be measured from such line. The Board may, whenever it deems such lines desirable
or necessary, require the showing on the plat of specific setback lines which
may vary from lot to lot, provided that the front setback shall be not less
than the zoning requirement nor more than 20% greater than the zoning setback.
E.Â
Double frontage. Double-frontage lots, other than corner
lots, shall be avoided except where deemed essential by the Board in order
to provide separation of residential development from traffic arteries or
to overcome specific disadvantages of topography and orientation. An easement
or reserve strip at least 20 feet in width and across which there shall be
no right of access shall be provided along the line of lots abutting such
traffic artery or other disadvantageous use, and such easement shall be planted
and maintained as may be approved by the Board.
