A. 
All streets and highways shall be of sufficient width and suitable grade and shall be suitably located to accommodate the prospective traffic, to afford adequate light and air, to facilitate fire protection and to provide access of fire-fighting equipment to buildings, and all streets or other appropriate public places shown on a plat shall be suitably graded and paved or otherwise suitably improved, and street signs, sidewalks, streetlighting standards, curbs, gutters, street trees, water mains, sewage disposal systems and storm drains shall be installed, all in accordance with standards, specifications and procedures based on the classification of streets as determined by the Village Engineer and other appropriate Village departments or officers. No street shall be constructed having less than the minimum specifications for new highways to be taken over by the Village as established and amended from time to time by resolution of the Village Board.
B. 
The proposed subdivision shall conform to the minimum requirements of Chapter 310, Zoning, and in general to the Official Map and Comprehensive Plan, if any.
C. 
The arrangement of streets in the subdivision shall provide for the continuation of the streets in any adjoining subdivision or for their proper projection when adjoining property is not subdivided and shall be of a width at least as great as that of such existing connecting streets and in no case less than 50 feet in width.
D. 
It shall be the responsibility of the developer of property adjacent to a dead-end street or cul-de-sac, where the Planning Board deems that such street be continued, to construct such extension in compliance with the street construction standards of the Village and to return all lands in the right-of-way of a cul-de-sac in excess of Village street standards to the fronting property owner or owners in the condition that existed prior to the construction of the cul-de-sac.
E. 
Dead-end or cul-de-sac streets shall not in general exceed 400 feet in length and shall be equipped with a turnaround roadway with a minimum diameter of right-of-way of 140 feet and a minimum outside diameter of traveled way of 120 feet unless the Planning Board approves an equally safe and convenient form of turning space.
F. 
Block lengths generally shall not exceed 1,200 feet in length.
G. 
A pedestrian right-of-way not less than 10 feet wide shall be provided near and through the center of all blocks over 600 feet long and shall be paved with a walk at least four feet wide.
H. 
Intersections of streets shall be at angles as close to 90° as possible, and in no case shall two streets intersect at any angle smaller than 60°. To this end an oblique street should be curved approaching an intersection. Where three or more streets intersect, a traffic circle or other special treatment may be required by the Planning Board. At block corners the traveled way shall be rounded with a curve having a radius of not less than 25 feet, and property lines shall be adjusted accordingly.
I. 
Side lines or lots, so far as practicable, shall be at right angles or radial to street lines.
J. 
Comer lots shall be increased in size wherever necessary so as to provide a side yard facing upon the cross street with a depth not less than the front yard requirement of Chapter 310, Zoning, for such cross street.
K. 
Grades of all streets shall be the reasonable minimum, but shall not be less than 0.5% nor more than 5.0% for major or Village arterial streets nor more than 10% for collector or minor streets.
L. 
Paved rear service streets of not less than 20 feet in width or, in lieu thereof, adequate off-street loading space, suitably surfaced, shall be provided in connection with all lots designated for commercial use.
M. 
Land shall not be platted for residential or any other subdivision use if it is of such a character that it cannot be safely used for such purposes without danger to health or peril from fire, flood or other menace.
N. 
If a tract is subdivided into larger parcels than normal building lots, such parcels shall be arranged so as to allow the opening of future streets and logical further resubdivision.
O. 
In general, no reserve strips controlling access to land dedicated or to be dedicated to public use will be permitted.
P. 
In general, street lines on the same side of the street and within a block deflecting from each other at any one point more than 10° shall be connected with a curve, the radius of which for the inner street lines shall not be less than 350 feet on major or Village arterial streets, 250 feet on collector streets and 100 feet on local or minor streets. The outer street lines in each case shall be parallel to such inner street line.
Q. 
Areas for parks and playgrounds shall be of reasonable size for neighborhood playgrounds or other recreational uses. No arbitrary percentage of area will be insisted upon by the Planning Board, but in general, subdividers should set aside not less than 10% of the area for these purposes. If the Planning Board determines that a suitable park or parks of adequate size cannot be properly located in any subdivision or that it is otherwise impractical to provide land for park purposes in such subdivision, the Planning Board may require as a condition to approval of the subdivision plat the payment to the Village of the sum of $3,500 per lot for each lot in the subdivision, which amount is hereby determined by the Village Board as suitable for such purpose. The amounts so paid shall be used for acquisition of parks and operation thereof pursuant to § 7-730 of the Village Law.
R. 
In general, existing trees over one foot in diameter four feet above ground level shall be preserved by the subdivider.
S. 
If any topsoil is removed from its natural position in the process of grading the subdivision site, such topsoil shall be replaced to a depth approximately equivalent to that existing prior to such grading except in streets, driveways and foundation areas.
T. 
Sewerage facilities. All subdivisions shall be required to be serviced by municipal sewer unless otherwise waived by the Village Board.
The applicant shall request from the Planning Board copies of existing aerial photography and topographic maps as prepared by the Village, and the Planning Board shall provide said copies, suitable for use by the applicant, if available, at a cost to the applicant established by the Village Board in Chapter 143, Fees. The applicant shall use these photographs and maps to the maximum extent possible in the preparation of his preliminary and final plats.
