The owner shall observe the following general requirements and principles of land subdivision.
A. 
The arrangement, character, extent, width and location of all streets shall conform to the Comprehensive Plan and to the Official Maps of the Village, town and county, if any, and shall be considered in their relation to other existing and planned streets, to topographical conditions, to public conveniences and safety and in their appropriate relation to the proposed uses of land to be served and/or abutted by such streets.
B. 
Where such is not shown in the Comprehensive Plan, the arrangement of streets in a subdivision shall either:
(1) 
Provide for the continuation or appropriate projection of existing principal streets in surrounding areas; or
(2) 
Conform to a plan for the neighborhood approved or adopted by the Planning Board to meet a particular situation where topographical or other conditions make continuance or conformance to existing streets impracticable or undesirable.
C. 
Minor streets shall be so laid out that their use by through traffic will be discouraged.
D. 
Where a subdivision abuts or contains an existing or proposed arterial street, the Planning Board may require marginal-access streets to have reverse frontage with screen planting contained in a nonaccess reservation along the rear property line or other such treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.
E. 
Where a subdivision abuts or contains a railroad right-of-way or controlled-access highway right-of-way, the Planning Board may require a street approximately parallel to and on each side of such right-of-way (marginal-access street) 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.
F. 
Reserve strips controlling access to streets, water or sewage treatment plants or to other land dedicated or to be dedicated to public use shall be prohibited except where their control is definitely placed in the Village under conditions approved by the Planning Board.
G. 
Cross (four-cornered) streets shall be avoided insofar as practicable in residential zone areas restricted to one-, two- or three-family dwellings.
H. 
Street jogs shall be avoided, and where no other system shall suffice, center-line offsets shall not be less than 150 feet.
I. 
A tangent shall be introduced between reverse curves and shall be of at least 100 feet in length on minor and collector streets and of such length as may be deemed necessary by the Planning Board for arterial streets.
J. 
When continuing street lines of collector streets deflect from each other at any one point by more than 10°, they shall be connected by a curve with a radius at the inner-street right-of-way line of not less than 350 feet; where continuing street lines of arterial streets deflect from each other by more than five degrees, they shall be connected by a curve with a radius of not less than 800 feet.
K. 
Streets shall be laid out so as to intersect as nearly as possible at right angles, and in no case shall any angle of intersection be less than 75°. Any change in street alignment to meet this requirement shall occur at least 100 feet from the intersection.
L. 
Street right-of-way lines at street intersections shall be rounded with a radius of 25 feet or with a greater radius where the Planning Board may deem it necessary. The Planning Board may permit comparable cutoffs or chords in place of rounded corners.
M. 
Street right-of-way widths.
(1) 
Street right-of-way widths shall be as shown on the Official Map[1] and where not shown thereon, shall not be less than as follows:
Street Type
Right-of-way Width
(feet)
Arterial
120
Collector
84
Minor and marginal-access
60
[1]
Editor's Note: The Official Map is one file at the Village offices.
(2) 
In exceptional circumstances, to permit optimum use of land, short streets of a minimum width of 50 feet might be permitted by the Planning Board.
N. 
Existing street rights-of-way within the subdivided property shall be widened as shown on the Official Map,[2] if any, to achieve the width appropriate to the type of street.
[2]
Editor's Note: The Official Map is on file at the Village offices.
O. 
Partial-width streets shall be prohibited regardless of location within or along the boundary of a subdivision.
P. 
Culs-de-sac shall not be longer than 800 feet and shall be provided with a turnaround at the closed end having a street right-of-way line diameter of at least 140 feet.
Q. 
Street grades shall not exceed the following, with due allowance for vertical curves, and with not less than 200 feet between changes of grade:
Street Type
Maximum Grade
(percent)
Arterial
4
Collector
6
Minor and marginal-access
7 (except that grades up to 10% may be permitted on short runs)
R. 
Sight distance over grades shall not be less than 200 feet. Sight distances around curves shall not be less than 200 feet.
S. 
Grades at street intersections shall be held to a maximum of 3% for a distance of 100 feet in any direction from the point of intersection of the street center lines.
T. 
Street drainage ditch grades shall not be less than 1.0%. Drainage structures and adequate ditches shall be provided by the owner to prevent ponding or damage to public or private property.
U. 
Limitation of access to streets shall be as follows:
(1) 
Minor streets: no limitation.
(2) 
Collector streets: no limitation.
(3) 
Arterial streets: restricted as far as practicable.
V. 
Street names shall be cleared with the Village Planning Board and with the Village Board of Trustees to avoid duplications or use of similarly sounding or spelled names. Housing numbers should follow the standard practice of house numbering in the Village, if any.
A. 
Easements across lots or centered on rear or side lot lines shall be provided for utilities where necessary and shall not be less than 20 feet wide.
B. 
Where a subdivision is traversed by a watercourse, drainageway, channel or stream, there shall be provided a stormwater easement or drainage right-of-way of not less than 20 feet in width conforming substantially with the lines of such watercourse and such further width or construction, or both, as will be adequate for the purpose. Parallel streets or parkways may be required in connection therewith.
C. 
If a street is being dedicated in sections, a temporary turnaround easement of 120 feet in diameter must be granted at its end. Such easement will be automatically terminated when the street is extended.
A. 
The lengths, widths and shapes of blocks shall be determined with due regard to:
(1) 
Provision of adequate building sites suitable to the special needs of the type of use contemplated.
(2) 
Zoning requirements as to lot sizes and dimensions.
(3) 
Needs for convenient access, circulation, control and safety of street traffic.
(4) 
Limitations and opportunities of topography.
B. 
Block length generally shall not exceed 1,200 feet nor shall they be less than 300 feet unless unusual topographic conditions make it impractical to limit said distances, and, under such circumstances, the Planning Board may vary such distances. Generally, the block depth shall be at least twice the minimum lot depth permitted in the Zoning Ordinance.[1]
[1]
Editor's Note: See Ch. 205, Zoning.
C. 
Intersections with arterial streets should be held to a minimum and preferably spaced at least 1,200 feet apart.
D. 
Pedestrian crosswalks not less than 10 feet in width, property line to property line, shall be required where deemed essential to provide circulations or access to schools, playgrounds, shopping centers, transportation and other community facilities and generally where block lengths are in excess of 800 feet.
E. 
Sidewalks shall be required where deemed essential to provide circulation or access to schools, playgrounds, shopping centers, transportation and other community facilities.
A. 
The size, width, depth, shape, orientation and yards of lots shall be not less than specified in the Zoning Ordinance[1] for the district in which the lots are located and shall be appropriate for the type of development, the use contemplated and the economic feasibility of the contemplated or future utilities.
[1]
Editor's Note: See Ch. 205, Zoning.
B. 
Land subject to flooding shall not be platted for residential occupancy nor for such other uses as may increase danger to life or property or aggravate the flood hazard.
C. 
Residential lot dimensions where not served by public sewer shall be such to meet the requirements of Article VI of this chapter.
D. 
In case a tract is subdivided into larger parcels than ordinary building lots and especially where lots are more than double the minimum required area for the zoning district, such parcels shall be arranged so as to allow the opening of future streets, logical further subdivisions and for the economy of establishing future utilities.
E. 
Corner lots for residential use shall have sufficient extra width to permit appropriate building setback from both streets.
F. 
The subdividing of the land shall be such as to provide, by means of a public street, each lot with satisfactory access to an existing public street or highway.
G. 
Double-frontage and reverse-frontage lots should be avoided except where essential to provide separation of residential development from traffic arteries or to overcome specific disadvantages of topography and orientation. A planting screen easement at least 20 feet wide across which there shall be no right of access shall be provided along the rear line of such lots abutting such a major traffic artery or other disadvantageous use.
H. 
Side lot lines shall be substantially at right angles or radial to street right-of-way lines.
I. 
Off-street parking shall be provided and other requirements shall be met in compliance with the area and bulk regulations in the Zoning Ordinance.[2]

Editor's Note: See Ch. 205, Zoning.
A. 
The owner shall dedicate to the Village land usable for recreational purposes equal in size to 5% of the owner's tract. This land shall be used by the Village for parks, playgrounds or for other specific public recreational uses as deemed desirable by the Planning Board. However, if the Planning Board should consider an owner's tract too small and that the dedication of 5% of the total area is not of a size that would make it usable for a public purpose, the Village Board of Trustees shall direct the owner to make a monetary payment to the Village in lieu of land. This payment must be equal to 5% of the market value of the total tract prior to subdivision and can not be used by the Village for any purpose other than the purchase or improvement of land to be used for such public uses serving the neighborhood as indicated above.
B. 
Usable areas or areas bordering streams, lakes or other watercourses can be given special consideration by the Planning Board in excess of the five-percent minimum. The Planning Board may recommend that the Village Board of Trustees accept these areas as a gift or purchase them should they be desirable for public open spaces.
C. 
Where such sites and open spaces are not shown on the Comprehensive Plan and where deemed essential by the Planning Board, upon consideration of the particular type of development proposed in the subdivision and especially in large-scale neighborhood unit developments, the Planning Board may recommend that the Village Board of Trustees require the dedication or reservation of areas in excess of the five-percent minimum. Under such conditions a monetary payment at fair-market value prior to subdivision will be made to the owner to compensate his/her loss in excess of the five-percent contribution.
A. 
Existing trees within the subdivision shall be preserved insofar as is possible, and an appropriate overlay of the preliminary plat showing the proposed location and species of street trees to be retained and those to be cut down shall be submitted as described in Article IV of this chapter (see also Article VI of this chapter).
B. 
Street trees not less than one on the front of each lot and not more than 50 feet apart between street intersections nor more than 60 feet from a street intersection shall be required in new subdivisions whenever there are no existing woodlands unless exempted by the Planning Board. Before the trees are planted, an appropriate overlay of the preliminary plat as described in Article IV of this chapter shall be submitted to the Planning Board for study and recombination, and the Board shall prevent the planting of certain species that are subject to pests or disease or which might eventually tend to become nuisances.
C. 
No trees, hedges, shrubs, series of walls, etc., shall be placed within the street right-of-way or permitted outside a corner radius of 50 feet which would obstruct vision from motor cars.
