The standards outlined in this article shall be applied by the
Planning Commission in evaluating plans for proposed subdivisions.
The standards outlined herein shall be considered minimum standards,
and the Planning Commission may require more restrictive standards.
Whenever Borough or other applicable regulations impose more restrictive
standards, such other regulations shall control.
The location of the subdivision shall conform to the General Plan for the Borough, and the use of land in the subdivision shall conform to Chapter
475, Zoning, of the Montgomery Borough Code.
A. Hazardous areas. Land subject to hazards to life, health, or property
as may arise from fire, floods, disease, excessive noise, falling
aircraft, or considered uninhabitable for other reasons, may not be
subdivided for building purposes unless:
(1) The hazard has been eliminated; or
(2) The plans show adequate safeguards against the hazards.
B. Coordination with adjacent subdivisions. The subdivision shall be
coordinated with adjacent existing or proposed subdivisions.
Intersections involving the junction of more than two streets
are prohibited. Permitted intersections shall conform to the following:
A. Design.
(1) Streets shall intersect as nearly as possible at right angles. No
street shall intersect another at an angle of less than 60°.
(2) Streets entering opposite sides of another street shall be laid out
either directly opposite one another or with a minimum offset of 125
feet as measured between their center lines.
(3) Minimum curb or edge of pavement radii at intersections involving
only local streets shall be not less than 15 feet, and not less than
25 feet for intersections involving other streets.
(4) Minimum right-of-way radii shall be not less than 25 feet for all
intersections.
B. Clear sight triangle. There shall be a clear sight triangle of 50
feet measured along the center line from the point of intersection.
No buildings or obstructions are permitted in the area.
C. Distance between intersections. Streets shall not enter into arterial
or collector streets at intervals of less than 800 feet as measured
from the center lines.
Permanently designed cul-de-sac streets shall not exceed 600
feet in length. They shall be provided with a paved turnaround having
a minimum radius of 40 feet to the outside curb or edge of pavement,
and with a right-of-way radius of 50 feet.
In general, the length, depth, and shape of blocks shall be
determined with regard to the proposed use of the land. Blocks should
be 500 feet to 1,600 feet in length and be two lot depths in width.
All lots shall conform to the provisions of the Borough of Montgomery
Zoning Ordinance.
A. Lot layout. All lots shall abut a street. Side lot lines shall be
substantially at right angles or radial to street lines.
B. Corner lots. Corner residential lots shall have additional width
to permit sufficient setbacks from both streets.
Building setback lines shall conform to Chapter
475, Zoning, of the Montgomery Borough Code.
In reviewing subdivision plans, the Planning Commission will
consider the adequacy of existing or proposed community facilities
to serve the additional dwelling units proposed by the subdivision,
and may request the reservation or dedication of land for the facilities.
For subdivisions containing 50 or more lots, the Planning Commission,
if it determines that recreation space is necessary, shall require
the dedication or grant in easement of 5% of the total area of all
lots or 10,000 square feet, whichever is greater. The Planning Commission
may require dedication of land for recreation space if the subdivision
contains less than 50 lots, or if a development of rental units should
have such an area.
Subdivisions shall be connected to public sewer and water systems.
A. Approval of public sewer or water systems. The subdivider shall provide
evidence that the proposed system to be served by extension of existing
systems has been reviewed and approved for service by the owners of
the public system, or in the case of new systems, shall obtain approval
of the Pennsylvania Department of Health.
Storm sewers, culverts, and related facilities shall be required,
as necessary, to permit the unimpeded flow of natural watercourses
and ensure the drainage of low points along the street line. Facilities
shall be designed to handle the runoff from the entire drainage basin.
A. Storm sewers. When adequate existing storm sewers are readily accessible,
the subdivider shall connect his stormwater facilities to these existing
sewers.
B. Abutting properties. Special consideration shall be given to preventing
excess runoff onto adjacent properties.
In developments laid out on irregular terrain, it is likely
that both cuts and fills will be a major aspect of the completed plan.
In order to eliminate difficulty in maintaining banks and slopes on
the part of the lot owners, to eliminate hazards to safety, and to
minimize maintenance problems which are caused by an improper sloping
of banks and fills, the following design standards must be adhered
to:
A. Where a development of lots abuts an existing Borough road, the slope
of banks as measured perpendicular to the ditch line shall not exceed
30%.
B. The slope of banks of lots abutting a newly-constructed street in
a development shall not exceed 30% as measured perpendicular to the
right-of-way line of such new street.
C. All such banks created by cuts and fills shall be suitably planted
with perennial grasses or other vegetation to prevent erosion.
