A. 
The arrangement, character, extent, width, grade and location of all streets shall conform to the General Development or Master Plan and to the Official Map, if any, and shall be considered in their relation to other existing and planned streets, to topographical conditions, to public convenience and safety and in their appropriate relation to the proposed uses of land to be served and/or abutted by such streets.
B. 
Where not shown in the General Development Plan, streets in a subdivision shall:
(1) 
Provide for the continuation or appropriate projection of existing principal streets in surrounding areas; or
(2) 
Conform to a plan for the adjacent area approved or adopted by the Planning Board to meet a particular situation where topographical or other conditions make continuance of or conformance with existing streets impracticable.
C. 
Minor streets shall be so laid out that their use by through traffic will be discouraged.
D. 
Where a subdivision abuts on or contains an existing or proposed arterial street, the Planning Board may require marginal access streets, reverse frontage with screen planting contained in a nonaccess reservation along the rear property line, deep lots with or without 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.
E. 
Where a subdivision borders on 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, at a distance suitable for the appropriate use of the intervening land, as for park purposes in residential districts or for business, 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 plants or sewage treatment plants shall be prohibited except where their control is definitely placed in the town under conditions approved by the Town Board.

Street jogs with center-line offsets of less than 125 feet shall be avoided.
H. 
A tangent at least 100 feet long shall be introduced between reverse curves on arterial and collector streets.
I. 
Streets shall be laid out so as to intersect as nearly as possible at right angles, and no street shall intersect any other street at less than 75º. The Planning Board may waive this requirement if adequate channelizing or divisional islands are provided to ensure traffic safety.
J. 
Property lines at street intersections shall be rounded with a radius of 10 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.

(2) 
No trees shall be planted or maintained within any required right-of-way.
M. 
Half streets shall be prohibited except where essential to the reasonable development of the subdivision in conformity with the other requirements of these regulations; and where the Planning Board finds it will be practicable to require the dedication of the other half when the adjoining property is subdivided, the other half of the street shall be platted within such tract.
N. 
Dead-end streets, designed to be so permanently, shall in general be not longer than 500 feet and shall be provided at the closed end with a turnaround having an outside roadway diameter of at least 120 feet. Dead-end streets shall be graded to drain to the intersection, or a utility easement provided and approved by the Town Engineer for drainage from the closed end.
O.

Street Type
Maximum % Grade
Arterial street
4
Collector street
6
Minor street
8
Marginal access street
8
Q. 
In order to facilitate drainage, no street grade shall be less than four-tenths percent (0.4%) when possible, but in no event less than three-tenths percent (0.3%).
A. 
Alleys may be required in business, commercial and industrial districts, but it is recommended that other definite and assured provision be made for service access, such as off-street loading, unloading and parking consistent with and adequate for the uses proposed.
B. 
The width of an alley, if required, shall not be less than 20 feet and shall be paved full width with an invert for center drainage.
C. 
Dead-end alleys shall be avoided where possible, but if unavoidable shall be provided with adequate turnaround facilities at the closed end, as required by the Planning Board, and shall be graded to drain to the exit.
A. 
Easements across lots or centered on rear or side lot lines shall be provided for utilities where necessary and shall be at least 12 feet wide.
B. 
Where a subdivision is traversed by a watercourse, drainageway or channel, there shall be provided a stormwater easement or drainage right-of-way conforming substantially with the lines of such watercourse, and such further width or construction, or both, as will be adequate for the drainage purpose.
A. 
Block lengths generally shall not exceed 1,600 feet nor be less than 400 feet. Block widths shall not be less than 240 feet.
B. 
Intersections with arterial streets should be held to a minimum and preferably spaced at least 1,000 feet apart.
C. 
Pedestrian crosswalks, right-of-way not less than 10 feet wide, may be required where deemed essential to provide circulation or access to schools, playgrounds, shopping centers, transportation and other community facilities.
A. 
The area, width and the minimum building setback lines shall conform to the requirements of the Zoning Ordinance[1] and to the following standards:
(1) 
Residential lots not served by a public sewerage system shall meet the requirements of the Zoning Ordinance for usable area. Unless specifically approved by the County Health Department, the term "usable area" herein includes the general area of the lot or plot which may be utilized for proposed construction and for normal and reasonable development of the area for the type of occupancy proposed, exclusive of lakes, streams, ponds, swamps, areas of exposed or underlying rock, hardpan or other impervious stratum within four feet of the surface and marginal areas subject to flooding along streams or other bodies of water.
(2) 
Depth and width of properties reserved or laid out for business, commercial and industrial purposes shall be adequate to provide for the off-street service and parking facilities required by the type of use and development contemplated, as may be required by the Zoning Ordinance.
[1]
Editor's Note: See Ch. 120, Zoning.
B. 
Land subject to flooding shall not be platted for residential occupancy nor for such uses as may increase danger to life or property or aggravate the flood hazard.
C. 
The subdividing of the land shall be such as to provide each lot with satisfactory access from an existing or proposed public street. Where a tract is subdivided into parcels larger than normal building lots, such parcels shall be planned to permit the opening of future streets and logical further resubdivision.
D. 
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 10 feet wide, across which there shall be no right of access, shall be provided along the line of lots abutting such a traffic artery or other disadvantageous use.
E. 
Side lot lines shall be substantially at right angles or radial to street lines.
F. 
Rear lot lines coinciding with side lot lines shall be avoided wherever possible.
G. 
Corner lots shall have extra width, equal to the front yard setback required by the Zoning Ordinance, to permit appropriate building setback from and orientation to both streets. This requirement may be modified or waived by the Planning Board in appropriate cases.
Where deemed essential by the Planning Board upon consideration of the particular type of development proposed in the subdivision, or where a proposed park, playground or other recreational public site shown in the General Development Plan is located in whole or in part in a subdivision, the Planning Board may require the reservation of areas or sites of a character, extent and location suitable to the needs created by such development for a park or parks, playground or other recreational uses. The Planning Board will recommend to the Town Board that the appropriate local authority negotiate for the outright purchase of such sites.

[Added 8-23-1999]
A. 
The developer is responsible to provide two deciduous trees per subdivision lot. Corner lots will require an additional two trees. The trees are to have a minimum caliper of 2 1/2 inches above the ground. Trees are to be planted parallel to the street at a location two feet outside the right-of-way or trees may be planted at the direction of the Planning Board. Trees should be spaced evenly and should avoid underground utilities. The tree species are to be selected from a list provided by the Planning Department. Trees are to be planted prior to the issuance of a certificate of occupancy (CO). The developer is responsible to replace any dead or diseased tree for a period of one year after the CO is issued. Tree planting requirements can be waived or altered only with Planning Board approval.
B. 
Between the 31st of October and the 1st day of April of the succeeding year, a CO may be issued upon the submission of an agreement, in writing, by the person to whom the permit was issued, and signed by him, and the posting of $250 for performance and compliance with all requirements herein and completion of required planting and restoration work to the satisfaction of the designated official on or before the 1st day of May. The bond shall continue until the planting and restoration work is completed in accordance with the agreement and the Town Building Department. The Town Building Department shall have the right to declare the performance bond in default and to apply the proceeds thereof to the completion of the required work and to enforce as a lien upon the property and deficiency.
C. 
Such section shall take effect 10 days after such publication and posting, but such amendments shall take effect from the date of its service against a person served personally with a copy thereof certified by the Town Clerk under the corporate seal of the town and showing the date of its passage and entry in the minutes.
