A. Horizontal alignment shall have:
(1) A minimum radius between intersections of 150 feet.
(2) A minimum tangent between reverse curves of 50 feet.
(3) A minimum radius of 12 feet at the property line at the intersection
of street rights-of-way, except that intersections of any highway
with a major street shall have a minimum radius of 40 feet and those
with a minor street shall have a radius of 25 feet.
B. Vertical alignment shall have:
(2) A maximum grade of 6% (8% on minor streets); or
(3) A maximum grade for less than 200 feet of 10%; and
(4) A maximum grade within 100 feet of a right-of-way intersection of
3%; and
(5) All changes in grade of more than 0.8% shall be connected by vertical
curves; and
(6) The length (L) in feet of a vertical curve shall be related to the
algebraic difference in the percent of grade (A) and a constant (K=28
for minor streets and K=65 for secondary streets) according to the
following formula: L=KA.
C. Sight distances shall be at least:
(1) One thousand feet for primary highways.
(2) Five hundred feet for secondary highways.
(3) Three hundred feet for all other streets.
D. Right-of-way widths and dimensions for improvements shall be in accordance with Table I, Minimum Required Construction Types and Right-of-Way Widths, in §
238-23.
E. The street pattern within a subdivision shall be orderly. Where appropriate,
a major street shall be indicated for more direct access to minor
streets.
F. In regulating subdivisions, these provisions shall be considered
the minimum requirements generally consistent with the public welfare,
and the Planning Board, in consultation with the Village Engineer,

be deemed necessary for the public good.
