[Amended 11-16-2020 by L.L. No. 2-2020]
A. General. The arrangement, character, extent, width, grade and location
of all streets shall be considered in their relation to existing and
planned streets, to existing topography and natural features, to public
convenience and safety and in their appropriate relation to the proposed
uses of the land to be served by such streets.
B. Relation to topography. Street layouts and grades shall be related
appropriately to the existing topography, and streets shall be arranged
to obtain as many as possible of the building sites at or above the
grades of the streets. Steep grades shall be avoided, as well as combinations
of steep grades and curves.
C. Arrangement. Proposed streets shall be of sufficient width, suitably
located and adequately constructed to accommodate the prospective
traffic and to facilitate drainage and to afford access for firefighting,
snow removal and road maintenance equipment. Such streets shall be
coordinated so as to compose a convenient system and to cause no undue
hardship to adjoining properties.
D. Arrangements. The arrangement of streets shall provide for the continuation
of principal streets between adjacent properties when such continuation
is necessary for convenient movement of traffic, effective fire protection
or efficient provision of utilities. If the adjacent property is undeveloped
and the street must be a dead-end street temporarily, the right-of-way
shall be extended to the property line. A temporary circular turnaround
shall be provided on all temporary dead-end streets, with the notation
on the plat that land outside the normal street right-of-way shall
revert to abutters whenever the street is continued.
E. Intersections.
(1) Street jogs with center-line offsets of less than 125 feet shall
not be permitted except with the approval of the Board.
(2) Intersections of streets shall be at angles as close to 90° as
possible. Toward this end, an oblique street should be curved approaching
an intersection and should be approximately at right angles for at
least 100 feet therefrom. Where three or more streets intersect, a
turning circle or other special treatment may be required by the Board.
Wherever two streets intersect at an angle smaller than 75°, the
right-of-way returns and the relation of the gutter grades shall be
given special treatment, as determined by the Board, and islands to
channelize traffic may be required.
(3) 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 at important traffic
intersections. A distance at least equal to the minimum required lot
depth plus 25 feet shall be maintained between center lines of offset
intersecting streets. Grades shall be limited to no more than 2% within
50 feet of an intersection.
F. Treatment along major arterial streets. Where a subdivision abuts
or contains an existing or proposed major arterial street, the Board
may require marginal access streets, reverse frontage with screen
planting contained in a nonaccess reservation along the rear property
line, deep lots with 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.
G. Dead-end streets.
(1) Where a street does not extend to the boundary of the subdivision and its continuation is not required by the Board for access to adjoining property, its terminus shall normally not be nearer to such boundary than 100 feet or the minimum lot depth prescribed by Chapter
300, Zoning, of the Code of the Village of Old Brookville, whichever is greater. However, the Board shall require the reservation of a twenty-foot-wide easement to accommodate drainage facilities, pedestrian traffic or utilities.
(2) For greater convenience to traffic and more effective police and
fire protection, permanent dead-end streets shall be limited in length
to 900 feet and shall be provided at the closed end with a turnaround
having an outside roadway diameter of at least 80 feet and a street
property line diameter of at least 100 feet. Where it is impossible
to subdivide a property except by a dead-end road which is longer
than 900 feet, the Board may permit a greater length, provided that
a divided roadway with center mall is constructed in a seventy-foot
right-of-way (or greater width, if required) in such a manner that
either side of the roadway could be used, in emergencies, for two-way
traffic.
H. Design standards for streets. Streets shall meet the design standards
set forth below, and the Board shall determine the type of each street.
Standards do not cover major streets which would be built by the state
or county.
(1) Widths. Generally, the width shall be not less than the following:
(b)
Secondary street: 60 feet.
(d)
Marginal access street: 40 feet.
(2) Grades.
(a)
Grades of all streets shall be the reasonable minimum and, unless
warranted by extenuating circumstances, shall be as follows:
[1]
Local and marginal streets: not less than 1.0% or more than
8%.
[2]
Secondary and major streets: not less than 1.0% or more than
5%.
(b)
Gradients shall be used to facilitate surface drainage to proper
natural or artificial outlets.
(c)
Changes in grade. All changes in street grades shall be connected
by vertical curves of sufficient radius to provide a smooth transition
and proper sight distance, as approved by the Board.
(3) Tangents. A tangent at least 100 feet in length shall be introduced
between reverse curves on all streets, except where a greater length
is required by the Board.
(4) Curves. When the alignment of the street changes more than 10°,
the tangents shall be connected by a curve with a radius of not less
than 200 feet, unless a greater radius is required by the Board to
ensure a proper sight distance.
I. Reserve strips. Reserve strips controlling access to streets shall
be prohibited except where their control is placed in the Village
under conditions approved by the Board.
J. Property lines at intersections. Property lines at intersections
shall be established in such a manner as to place within the street
right-of-way the triangular area which is formed by the street lines
extended and a straight line adjoining points on said street lines
30 feet distant from their point of intersection.
K. Street names. All streets shall be named, and such names shall be
approved by the Board. Names shall be sufficiently different in sound
and in spelling from other street names in the Village or adjoining
municipalities so as not to cause confusion. A street which is a continuation
of an existing street shall bear the same name. In general, street
names shall conform to the following classifications:
(1) Road: major or secondary street.
(2) Drive or lane: local residential street, except as follows:
(a)
Court or place: permanent dead-end street.
(b)
Circle: street that returns to its starting point or a street
both ends of which intersect another street at different locations.
L. Fences or gates. No fence or gate shall be erected on or across any street within a subdivision, regardless of whether such street is intended to be public or private. Notwithstanding, nothing herein shall be interpreted to prevent the erection or construction of a fence or gate wholly contained within an individual lot pursuant to the provisions of §
300-13 of Chapter
300, Zoning, or as otherwise provided for in §
300-13.
