The Planning Board, in considering an application for the subdivision of land, shall be guided by the following considerations and standards.
A. 
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.
B. 
Conformity to Official Map and Village Plan. Subdivisions shall conform to the streets and parks shown on the Official Map of the Village, as it may be adopted, and shall be properly related to the Village Master Plan as it is developed and adopted by the Village Planning Board.
A. 
Location, width and improvement of streets. Streets shall be suitably located, of sufficient width and adequately improved to accommodate the prospective traffic and to afford satisfactory access to police, fire-fighting, snow removal or other road maintenance equipment, and shall be coordinated so as to compose a convenient system. The arrangement of streets shall be such as to cause no undue hardship to adjoining properties.
B. 
Widths of right-of-way.
(1) 
Streets shall have the following widths, unless otherwise indicated on the Village Plan:
(a) 
Minor street: 50 feet.
(2) 
Standards for street design (minor streets).
(a) 
Minimum width of right-of-way: 50 feet.
(b) 
Minimum width of pavement: 30 feet.
(c) 
Minimum width of horizontal curves: 100 feet but not less than 20 feet for each 1% algebraic difference of grade.
(d) 
Minimum length of tangents between reverse curves: 100 feet, except where excessive grades may be reduced to reasonable grades by shortening tangent.
(e) 
Maximum grade: 10%.
(f) 
Minimum grade: 1%.
(g) 
Minimum sight distance: 150 feet.
C. 
Relation to topography. Streets shall be logically related to the topography and all streets shall be arranged so as to obtain as many of the building sites as possible at or above the grades of the streets. A combination of steep grades and sharp curves shall be avoided.
D. 
Block size. Within any zoning district, block dimensions shall be at least twice the minimum lot depth and generally not more than 12 times the minimum lot width. In long blocks, the Planning Board may require the reservation through the block of a twenty-foot-wide easement to accommodate utilities or pedestrian traffic. (See § 66-15D.)
E. 
Intersections. 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 important traffic intersections. Within 40 feet of an intersection, streets shall be approximately at right angles and grades shall be limited to 1 1/2%. All street intersection corners shall be rounded by curves of at least 25 feet in radius at the property line. Within triangular areas formed by the intersecting street lines, for a distance of 75 feet from their intersection and the diagonals connecting the end points of these lines, visibility for traffic safety shall be provided by excavating, if necessary. Nothing in the way of fences, walls, hedges or other landscaping shall be permitted to obstruct such visibility.
F. 
Continuation of streets into adjacent property. The arrangement of streets shall provide for the continuation of principal streets between adjacent properties where such continuation is necessary for convenient movement of traffic, effective fire protection, efficient provision of utilities, and particularly where such is in accordance with the Village Plan, as it may be adopted. If the adjacent property is undeveloped and the street must be a dead-end street temporarily, the right-of-way and improvements shall be extended to the property line. A temporary circular turnaround of a minimum of 50 feet in radius shall be provided on all temporary dead-end streets, with the notation on the plat that land outside the street right-of-way shall revert to abutters whenever the street is continued. The Planning Board may limit temporary dead-end streets.
G. 
Permanent dead-end streets. Where a street does not extend to the boundary of the subdivision and its continuation is not needed for access to adjoining property, it shall be separated from such boundary by a distance of not less than the minimum lot depth prescribed by the zoning regulations for the zoning district in which the street is located. Reserve strips of land shall not be left between the end of a proposed street and an adjacent piece of property. However, the Planning Board may require the reservation of a twenty-foot-wide easement to accommodate pedestrian traffic or utilities. A circular turnaround of a minimum right-of-way radius of 50 feet shall be provided at the end of a permanent dead-end street. For greater convenience to traffic and more effective police and fire protection, permanent dead-end streets shall, in general, be limited in length to six times the minimum lot width for the zoning district.
H. 
Street names. All streets shall be named and such names shall be subject to the approval of the Planning Board. Names shall be sufficiently different in sound and in spelling from other street names in the Village so as not to cause confusion. A street which is a continuation of an existing street shall bear the same name.
A. 
Street improvements. Streets shall be graded and improved with pavement, street signs, sidewalks, streetlighting standards, curbs, gutters, street trees, water mains, sanitary sewers, storm drains and fire hydrants, except where waivers may be requested, and the Planning Board may waive, subject to appropriate conditions, such improvements as it considers are not requisite in the interest of the public health, safety and general welfare. If placed in the street right-of-way, underground utilities required by the Planning Board shall be placed between the paved roadway and street line to simplify location and repair of the lines. The subdivider shall install underground service connections at the property line of each lot before the street is paved. Such grading and improvements shall conform to the Village minimum road specifications (4 1/2 inches rolled stone, 1 1/2 inches blacktop, with regulation curbs), and shall be approved as to design and specifications by the Village's Engineer. The developer, before the approval of the final subdivision plat, shall complete all improvements to the satisfaction of the Village's Engineer, or post a performance bond sufficient to ensure the satisfactory completion of such improvements.
B. 
Nassau County requirements. The subdivider will be required to install such facilities for the drainage of streets as may be required by the Commissioner of Public Works of Nassau County. Any storage basins required by the Nassau County Department of Public Works and any other drainage facilities required to be installed shall be constructed and completed by the subdivider. All such drainage structures shall be maintained by the subdivider in good operating condition until such time as the land is released.
A. 
Lot arrangement. The lot arrangement shall be such that there will be no foreseeable difficulties, for reasons of topography or other conditions, in securing building permits to build on all lots in compliance with the Zoning Ordinance,[1] and in providing access to buildings on such lots from an approved street.
[1]
Editor's Note: See Ch. 80, Zoning.
B. 
Access across a watercourse. Where a watercourse separates the buildable area of a lot from the street by which it has access, provision shall be made for installation of a culvert or other structure of a design approved by the Village's Engineer.
C. 
Lot dimensions. Lot dimensions shall at least comply with the minimum standards of the Zoning Ordinance.[2] Where lots are more than double the minimum required area for the zoning district, the Planning Board may require that such lots be arranged so as to allow further subdivision and the opening of future streets where they would be necessary to serve such potential lots.
[2]
Editor's Note: See Ch. 80, Zoning.
D. 
Side lot lines. Side lot lines shall be at right angles to street lines unless a variation from this rule will give a better street or lot plan.
E. 
Access from major streets. Lots shall not, in general, derive access exclusively from a major street. Where driveway access from a major street may be necessary for several adjoining lots, the Planning Board may require that such lots be served by a combined access drive in order to limit possible traffic hazard on such street.
A. 
Parks and playgrounds. The Planning Board may require adequate, convenient and suitable areas for parks and playgrounds, or other recreational purposes, to be reserved on the plot but in no case more than 10% of the gross area of any subdivision. The area shall be shown and marked on the plat "reserved for park or playground purposes."
B. 
Widening or realignment of existing streets. Where the subdivision borders on an existing street, and the Official Map or Master Plan, as they may be adopted, indicated plans for realignment or widening of the street that would require reservation of some land of the subdivision, the Planning Board may require that such areas be shown and marked on the plat "reserved for street realignment (or widening) purposes."
C. 
Utility and drainage easements. Where topography or other conditions are such as to make impractical the inclusion of utilities or drainage facilities within street rights-of-way, perpetual unobstructed easements at least 20 feet in width for such utilities shall be provided across property outside the street lines and with satisfactory access to the street. Easements shall be indicated on the plat.
D. 
Easement for pedestrian access. The Planning Board, where it deems it necessary, may, in order to facilitate pedestrian access from streets to schools, parks, playgrounds or other nearby streets, require perpetual unobstructed easements at least 20 feet wide. Easements shall be indicated on the plat.
E. 
Responsibility for ownership of reservations. Ownership shall be clearly indicated on all reservations for parks and playground purposes.
A. 
Preservation of existing features. Existing features which would add value to residential development, such as large trees, watercourses and falls, historic spots and similar irreplaceable assets, should be preserved insofar as possible through harmonious design of the subdivision.
B. 
Self-imposed restrictions. The owner may place restrictions on the development greater than those required by the Zoning Ordinance.[1] Such restrictions, if any, shall be indicated on the final plat.
[1]
Editor's Note: See Ch. 80, Zoning.
C. 
Modification of standards. The Planning Board may, when authorized by the Board of Trustees pursuant to § 7-738 of the Village Law, modify the specified requirements in any individual case when, in the judgment of the Planning Board, such modification is in the public interest or will avoid the imposition of unnecessary individual hardship.
