All streets shall be arranged in conformity with the Borough
Official Plan of Streets and Highways, considered in relation to both
existing and planned streets and located so as to allow proper development
of surrounding properties. Secondary streets and through streets shall
be connected with such existing streets so as to form continuations
thereof. Residential streets shall be laid out so as to discourage
their use as secondary or through streets.
Streets shall be adjusted to the topography of the land so as
to produce usable lots and streets of reasonable grade. Low-lying
land subject to periodic flooding shall not be plotted for residential
development or for such other uses as may involve danger to the health,
safety, morals or general welfare of the citizens.
The shoulders shall be graded to the full width of the right-of-way
and provisions made for slopes beyond the right-of-way line.

County and state streets within the Borough shall, in addition to
the above, conform to the requirements of the respective highway departments.
B.
Culs-de-sac. The minimum width of the right-of-way shall be 50 feet,
and the minimum paving shall be 30 feet. A cul-de-sac shall have a
circular turnaround with a minimum paving radius of 40 feet. A cul-de-sac
will not be approved when a through street is practicable, nor shall
it exceed 500 feet in length, except that a temporary cul-de-sac will
be permitted where it is advisable to continue the street in the future
into abutting property, in which case the right-of-way approved and
to be dedicated shall be the full street width extended to the adjoining
property.
A.
Wherever practicable, right-of-way lines shall intersect at right
angles and shall be rounded by a tangential arc having a minimum radius
of 20 feet.
B.
Wherever practicable, curblines shall be rounded by a tangential
arc having a minimum radius of 30 feet.
C.
Wherever practicable, intersection with through highways shall be
kept to a minimum and shall be located at least 1,000 feet apart.
A.
Sight distance. A sight distance at the center line of at least 200
feet on secondary streets and 100 feet on residential streets at driver's
eye height of five feet shall be provided with respect to horizontal
alignment.
B.
Horizontal curves. Horizontal curves, wherever practicable, shall
have a minimum radius on the center line of 200 feet on secondary
streets and 150 feet on residential streets. Wherever practicable,
long radius curves should be used, rather than a series of curves
with short tangents; reverse curves should be separated by tangents;
super-elevation may be required; and minimum radius curves at the
end of long tangents are to be avoided. Wherever practicable, horizontal
and vertical curves shall not occur together, and where permitted,
minimum horizontal curves must not be combined with maximum grades.
C.
Vertical curves. Vertical curves shall be used at changes in grade
and shall be of such length so as to provide ease and safety of movement,
giving consideration to the degree of grade change, length of tangents,
visibility and drainage.
There shall be no grades in excess of 6% nor less than 1% except
by approval of the Borough Council. At intersections, wherever practicable,
grades should not exceed 3% for at least 50 feet measured from the
near side of the intersected street.
No street name shall be used which will duplicate or be confused
with the name of an existing street. Existing street names shall be
projected wherever possible. Signposts and name plates, approved by
the Borough, shall be placed at street intersections at the expense
of the subdivider. Street names are subject to the approval of Borough
Council.
No fence, hedge, wall, planting or other obstruction shall be
located in the right-of-way, and no obstruction shall be located at
intersections so as to obscure reasonable visibility.
Alleys are to be avoided but, where permitted or required, shall
have a right-of-way width of not less than 33 feet and a paved width
of not less than 20 feet. Adequate turning area shall be required
where an alley is dead-ended. An alley shall meet applicable street
standards and regulations.
Sidewalks shall be required on each side of every street and
on the side of every street on which the subdivision abuts, unless
otherwise determined by Borough Council. Sidewalks shall have a minimum
width of four feet, and the grade shall be continuous across driveways.
Driveway aprons shall be constructed of the same materials as required
for sidewalks. Sidewalk paving shall be four inches thick, except
in driveways, where it shall be at least six inches thick.
Blocks shall be planned to suit the topography and character
of the site. The length of the block should be governed by the demands
of traffic, efficiency of public and private services, the use of
the land and reasonable convenience. The length of blocks, as a rule,
should not be less than 800 feet, nor more than 1,320 feet. Crosswalks
may be required; in which case, the minimum right-of-way width shall
be 10 feet and the minimum sidewalk width four feet. Whenever practicable,
blocks shall be of such width as to provide two tiers of lots.
Trees, preferably of types found growing naturally in the soils
of the vicinity, planted in formal or informal groupings, are highly
desirable along streets. Trees may be planted within the right-of-way
subject to the rules and regulations of the Borough Shade Tree Commission.
Whenever practicable, provisions shall be made for suitable
open spaces for parks, playgrounds and recreational areas. Due consideration
shall be given to the preservation of natural features, including
large trees, groves, waterways, scenic points, historical spots and
other community assets for educational and religious use.
Reserve strips controlling access to streets or alleys will
not be approved.
Fire hydrants shall be installed at the expense of the developer
in such locations as shall be prescribed by the Fire Marshal and the
regulations of the Middle Department Association of Fire Underwriters.
Monuments of stone or concrete shall be placed at locations
designated by the Borough Engineer.
A.
An adequate and separate system of surface or storm drains conforming
to Borough specifications shall be required and located in the street
right-of-way and, where necessary, in other rights-of-way or easements.
Where required, drains shall be constructed to abutting boundary lines.
B.
The minimum size of pipe shall be 15 inches in diameter and a minimum
grade of 0.5%.
C.
Manholes shall be constructed at all changes in horizontal and vertical
alignment and shall be not more than 300 feet apart, unless a greater
distance is specifically permitted by the Borough Engineer.
D.
Inlets shall be open-mouth No. 1 city-type. Double open-mouth No.
1 city-type inlets may be required for unusual conditions. At street
intersections, inlets shall be located on the tangent and not on the
curved portion of the curb.
E.
Stormwater or surface water shall not be discharged over a sidewalk
but shall be collected in suitable inlets and conducted underground
to the curb or drain, if available.
F.
Bridges and culverts. Bridges and culverts shall be adequate in strength
and cross-sectional area and shall extend across the full width of
the right-of-way. When located on natural watercourses, the upstream
drainage area of which, from the point of construction, is 1/2 square
mile or more, the approval of the Department of Environmental Resources
shall be required, in addition to Borough approval.
[Amended 4-28-1980 by Ord. No. 80-13]
G.
Streams. Changes to natural streams shall be made only on approval
and as required to facilitate adequate flows. Consideration shall
be given to the convenience for future maintenance by providing rights-of-way
or easements. In addition to Borough requirements, approval of the
Department of Environmental Resources must be obtained where the upstream
drainage area is over 1/2 mile.
[Amended 4-28-1980 by Ord. No. 80-13]
A.
An adequate and separate system of sanitary sewers, conforming to
Borough specifications, shall be required wherever practicable and
shall be connected to the Borough sanitary sewer system. Where required,
sewers shall be constructed to abutting boundary lines.
B.
Capped sewers and laterals shall be required where no Borough sewer
presently exists for connection, but where such Borough sewer may
reasonably be expected to be constructed.
C.
Sanitary sewers shall have a minimum inside diameter of eight inches
and a minimum grade of 0.7%.
D.
Manholes shall be constructed at all changes in horizontal and vertical
alignment and shall be not more than 300 feet apart.
E.
Lateral connections shall be extended to the rear of the curb and
for use to each lot.
F.
Drainage easements of ample width shall be required in order to inspect
and maintain the sewers.
A.
