A.
The standards and requirements outlined herein shall be considered
minimum standards and requirements for the promotion of the public
health, safety and general welfare.
B.
If any provision of this chapter is shown by the applicant to be
unreasonable and causes undue hardship if strictly applied to a proposed
subdivision or land development, the Township Supervisors may grant
a waiver of such provision to such applicant so that substantial justice
may be done and the public interest secured, provided that such waiver
will not have the effect of nullifying the intent and purpose of this
chapter.
C.
In granting waivers, the Township Supervisors may impose such conditions
as will, in its judgment, secure substantially the objectives of the
standards or requirements so waived.
A.
All portions of a property being subdivided shall be taken up in
lots, streets, public lands or other proposed uses so that remnants
and landlocked areas shall not be created.
B.
Reserve strips controlling access to lots, public rights-of-way,
public lands or adjacent private lands shall be prohibited unless
their control is definitely placed in the Township under conditions
approved by the Board of Supervisors. The Board of Supervisors may
request inclusion of reserve strips to control access to major highways
or prohibit industrial or commercial access to secondary streets.
C.
In general, lot lines shall follow Township boundary lines rather
than cross them.
D.
Where trees, groves, waterways, scenic points, historic facilities
or other community assets and landmarks are located within a proposed
subdivision or land development, every possible means to the fullest
extent shall be provided to preserve these features. All features
shall be included on every set of plans.
E.
Subdivisions and land developments shall be properly designed in
order to prevent the necessity for excessive cut or fill.
F.
Subdivisions and land developments shall be subject to conditions set forth in the Floodplain Management Ordinance [Chapter 131]. (This is a separate ordinance and shall be secured from the Township offices.)
A.
The arrangement, character, extent, grade and location of streets
shall conform to the Falls Township Street Plan and shall be considered
in their relation to existing and planned streets, to topographical
conditions, to public convenience and safety and in their appropriate
relation to the proposed uses of the land to be served by such streets.
B.
Proposed streets shall further conform to such Township, county and
state street and highway plans as have been prepared. When ambiguity
or conflict exists, the Supervisors shall determine which plans shall
apply.
C.
Where such is not in the Falls Township Street Plan, the arrangement
of streets in a subdivision or land development shall either provide
for the continuation of appropriate projection of existing streets
in surrounding areas or conform to a plan for the neighborhood approved
or adopted by the Board of Supervisors to meet a particular situation
where topographical or other conditions make continuance or conformance
to existing streets impractical.
D.
Secondary streets shall be so laid out so that their use by through
traffic will be discouraged.
E.
Where a subdivision or development abuts or contains an existing
or proposed major highway, the Board of Supervisors, with the advice
of the Planning Commission, may require either marginal access streets,
reverse frontage with screen planting along the rear property line
or such other treatment as may be necessary for adequate protection
of properties, to afford separation of through and local traffic and
to reduce the number of access points on major highways.
F.
Streets that are extensions of or obviously in alignment with existing
streets shall bear the names of the existing streets in the Township
or within the post office address area. Street names shall not be
repeated or streets assigned names which may be confused with names
of existing streets, and all street names shall be subject to the
approval of the Board of Supervisors.
G.
Where the subdivision or development adjoins unsubdivided acreage,
the Supervisors may require stub streets to the boundary lines with
temporary easements for turnarounds.
H.
Whenever an applicant proposes to establish a street which is not
offered for dedication and not required to be offered for dedication,
he shall enter into an agreement with the Township binding himself,
his heirs and successors, to the requirement that such street shall
comply with the design standards for streets set forth in this chapter.
Said agreement shall be subject to the Township Solicitor's approval
and shall be recorded with and referenced on the subdivision plan.
Said agreement shall establish conditions under which the streets
may later be offered for dedication and stipulate among other things:
(1)
That the street shall be in good state of repair as certified by
the Township Engineer, or that the owners of the lots along it agree
to include with the offer of dedication sufficient money, as estimated
by the Township Engineer, to restore the street to conform to Township
specifications.
(2)
That an offer to dedicate the street shall be made only for the street
as a whole.
(3)
That the method of assessing repair costs shall be stipulated.
(4)
The agreement to offer the street for dedication by owners of 60%
of the lots shall be binding on owners of the remaining lots.
I.
The Township Supervisors will, when considering a preliminary major
subdivision or land development, in the interest of highway safety
and the safety of the area residents and in order to promote orderly
community development, require the owner/developer of any large commercial
complex, shopping centers, industrial parks or plants, housing projects,
apartment complexes, major educational or recreational facilities
and other significant traffic generators, to have prepared a traffic
impact study by a qualified traffic engineer with previous traffic
study experience and to meet with a representative of the Township
Engineer's office, the Township Traffic Engineer's office, and the
Pennsylvania Department of Highways to achieve a high level of design
from the standpoint of traffic. A traffic impact study is required
if one or more of the following criteria are met in the major subdivision
or land development:
(1)
Residential: 100 or more dwelling units.
(2)
Commercial: a commercial building or buildings consisting of 25,000
square feet or more of gross leasable floor space and all fast-food
restaurants.
(3)
Office: a development consisting of 25,000 square feet or more of
gross leasable floor space.
(4)
Industrial: a development consisting of 50,000 square feet or more
of gross leasable floor space.
(5)
Institutional:
(a)
Medical, public or educational: all developments of 25,000 square
feet or more of floor space.
(6)
When deemed appropriate by the Township, upon consideration of the
specific conditions of the proposal.
J.
Any applicant who encroaches within the legal right-of-way of a state
highway is required to obtain a highway occupancy permit from the
Pennsylvania Department of Transportation. The applicant shall submit
the highway occupancy permit plans and application to the Township
for review and comment prior to submission of the application to the
Department of Transportation, and shall include the Township on all
correspondence with the Department of Transportation regarding the
application.
K.
Any applicant who encroaches within the legal right-of-way of a Township
road is required to obtain a road occupancy permit from the Township
Manager after approval by the Township Engineer.
L.
The Township Traffic Engineer shall review all design issues related
to streets, driveways, and off-street parking facilities. There may
be certain instances where the proposed design of a street, driveway,
or off-street parking facility will be more complicated than these
design standards adequately describe. In those instances the Township
Traffic Engineer and the Township Engineer shall together determine
if the proposed design is acceptable.
A.

C.
Where a subdivision or land development abuts or contains an existing street of inadequate right-of-way width, a future right-of-way width shall be indicated on the plan, to conform to the standards under Subsection A. The Township shall prepare and maintain a comprehensive Falls Township Street Classification Map with the advice and consultation of the Falls Township Planning Commission.
A.
Horizontal alignment.
(1)
Horizontal curves shall be used when centerlines are deflected in
excess of 5°.
(2)
Minimum radii for horizontal curves shall be the minimum radius at
the centerline for curves which on principal arterial streets shall
be 960 feet, minor arterial streets shall be 760 feet, on collector
streets shall be 600 feet, on local streets shall be 450 feet, and
on limited residential streets shall be 250 feet. Proper superelevation
shall be provided for curves on arterial and collector streets. Superelevation
is a cartway where the paved surface is banked so that one side is
of a higher elevation than the opposite side.
(3)
Except for secondary streets, there shall be a tangent of at least
100 feet measured at the centerline between reverse curves. Secondary
streets shall have a tangent of at least 50 feet measured at the centerline
between reverse curves.

short curves and tangents.
B.
Vertical alignment. Vertical curves shall be used in changes of grade
exceeding 1% shall have a minimum K value of 30 and shall be designed
for maximum visibility. Intersections shall be approached on all sides
by leveling areas. Such leveling areas shall have a minimum length
of 50 feet measured from the edge of pavement of the traverse street,
within which no grade shall exceed a maximum of 4%.

A.
A minimum grade of 1/2% shall be established on all streets, except
that excessively flat grades through long vertical curves will not
be approved.
B.
Maximum grades of 5% shall generally apply. In exceptionally hilly
areas, a maximum grade of 6% on principal arterial streets, 7% on
minor arterial streets, 8% on collector streets, 9% on local streets,
and 10% on limited residential streets for a maximum distance of 1,500
feet will be permitted, subject to approval by the Township Engineer.
C.
A combination of minimum radius horizontal curves and maximum grades
will not be approved.
A.
Multiple intersections involving junction of more than two streets
shall be avoided.
B.
Streets shall be laid out to intersect as nearly as possible at right
angles. No street shall intersect another street at an angle of less
than 60°.
C.
Secondary streets shall not intersect on the same side of a major
highway at an interval of less than 800 feet between the nearest right-of-way
lines.
D.
Sight distances.
(1)
Proper clear sight triangles shall be maintained at all street intersections.
There shall be a clear sight line formed by a distance measured along
the centerline of the higher classified street, a distance perpendicular
to the said centerline measured along the centerline of the intersecting
street to a point 15 feet past the edge of the proposed cartway (or
curbline projected), and the line closing the triangle. There shall
be a total of two sight lines for each intersection (left and right).
The desirable sight distance along the centerline of the higher classified
street shall be as follows:
(a)
On a principal arterial street the distance shall be 700 feet.
(b)
On a minor arterial street the distance shall be 575 feet.
(c)
On a collector street the distance shall be 530 feet.
(d)
On a local street the distance shall be 435 feet.
(e)
On a limited residential street the distance shall be 300 feet.
(f)
For a commercial or industrial driveway intersecting a street
the distance shall be a minimum of 500 feet.
(g)
For a residential driveway the distance shall be 100 feet. (Ordinance 2000-7, Chapter 189, Driveway Ordinance.)
(h)
PennDOT roads shall have a sight distance in accordance with
PennDOT requirements.
(2)
These corner sight triangles shall be indicated on all plans of street
alignment. No existing or proposed structures or plantings, the highest
point of which is 3.5 feet above the road centerline, shall be permitted
in this area.
E.
Street curb intersections shall be rounded by a tangential arc with
a minimum radius of 20 feet for local and limited residential streets
and 30 feet for intersections which incorporate collector, principal
or minor arterial streets. Right-of-way intersections shall be rounded
by a tangential arc with a minimum radius of 11 feet for local or
marginal access streets, and a minimum radius of 12 feet for intersections
which incorporate collector or arterial streets. The right-of-way
intersection arc shall be parallel to the street curb arc.
F.
Local streets shall be so laid out that through traffic will be discouraged.
In general, the intersection interval of secondary streets entering
any existing or proposed streets from opposite directions shall be
located at not less than 125 feet from centerline to centerline of
the next nearest intersection point of the entering street from the
opposite side.
G.
The approaches to an intersection shall follow a straight course
for at least 50 feet from the future right-of-way line of the intersecting
street with a maximum grade of 4%.
H.
Intersections shall be approached from all sides by leveling areas.
Where the grade exceeds 7%, such leveling areas shall have a minimum
length of 50 feet measured from the edge of pavement of the transverse
street, within which no grade shall exceed 4%.
A.
Cul-de-sac streets permanently designed as such shall not exceed
in length the maximum length permitted for any block in accordance
with this chapter, except as waivers are permitted by the Board of
Supervisors upon request for a waiver presented by the applicant,
which request may be granted if it can be clearly shown that by reason
of unfavorable contours or irregular shape of the plot from which
the subdivision is being made, a normal street pattern cannot be established
or a hardship would be caused by not granting such a waiver.
B.
Cul-de-sac streets shall be secondary streets and conform to the provisions of § 191-31, except that any cul-de-sac permanently designed as such for residential use shall not exceed 500 feet in length. The minimum right-of-way shall be 50 feet and the minimum cartway shall be 26 feet. A cul-de-sac is a street that has no outlet and at the end of the roadway is a circle of a minimum required radius permitting vehicles to travel in a circular manner to the left reversing their direction with a continuous motion. The cul-de-sac is measured along the centerline from the center of the circle to the centerline of the nearest intersection with another street.
C.
A turnaround shall have a minimum right-of-way radius of 60 feet
and an outer paving radius of 40 feet.
(NOTE: Must also conform to Ord. No. 2000-7, Chapter 189, Driveways.)
A.
Driveways shall be located, designed and constructed as to provide a clear sight triangle with streets. For residential driveways, a triangle of clear sight shall be provided beginning at a point on the centerline of the driveway, 12 feet from the edge of the cartway of the street and a distance of 100 feet each way along the centerline of the street. Driveways in nonresidential zoning districts shall see § 191-34D for sight line distances. No existing or proposed structures or plantings, the highest point of which is 3.5 feet above the road centerline, shall be permitted in this area. A stopping area measured 20 feet behind the right-of-way line shall be provided, not to exceed a grade of 8%.
B.
Driveways, except in a Manufactured Home Community District, shall
be located not less than 40 feet from the nearest intersection corner
of corner lots and shall provide access to the street of lower classification
when a corner lot is bounded by streets of two different classifications
as herein defined, except that commercial and industrial developments
shall be prohibited from access to residential streets.
C.
Driveways in a Manufactured Home Community District shall be located
not less than 20 feet from the nearest intersection corner of corner
lots and shall provide access to the street of lower classification
when a corner lot is bounded by streets of two different classifications
as herein defined. Driveways in Manufactured Home Community District
shall be a minimum of 20 by 20 feet to provide for two-car, side-by-side
parking.
D.
All driveways, except for single-family dwellings, shall have curbs
meeting the specifications of the Falls Township Design Details and
Practices.[1] All driveways, except for jointly shared driveways in
a residential district, shall not be less than 12 feet from the property
line. Minimum design standards for the various types of development

all curblines in parking areas.
F.
Except at entrance and exit drives, all parking areas shall be set
back from the future right-of-way line as provided in the Falls Township
Zoning Ordinance[2] or at least five feet, whichever is greater. The distance
between this required setback and the future right-of-way shall be
permanently maintained as a planting strip.
G.
The following is required for all off-street parking facilities except
for single-family dwellings:
(1)
No one row of parking spaces shall exceed 20 spaces. Curbed raised
planting beds shall be at intervals not to exceed 20 spaces with beds
offset on alternating sides of parking rows. Curbed planting islands

(2)
Curbed raised planting beds shall be planted with one shade tree per bed. The selection of trees shall be from the approved shade tree listing in § 191-48H.
(3)
Where necessary for vehicular directional control and where determined
necessary by the Board of Supervisors for pedestrian safety, a double-loaded
row of parking spaces shall include a ten-foot-wide curbed raised
planting strip. The planting strip shall have curbed raised planting
beds at the ends of the parking row. The planting strip shall include
a sidewalk, light standards and street trees. The location of the
trees and the light standards shall not interfere with each other.
(4)
All parking areas shall have at least one tree of 1 1/2 inch caliper minimum for every six parking spaces in single rows and one tree of 1 1/2 inch caliper minimum for every 12 parking spaces in double-loaded rows of parking spaces.

and/or loading areas, and building complexes requiring area lighting
shall be adequately illuminated.
B.
The lighting plan in and around the parking areas, private driveways
and walkways shall provide for nonglare lights focused downward. The
light intensity provided at ground level shall be a minimum of 0.3
footcandle anywhere in the area to be illuminated. Lighting shall
be provided by fixtures with a mounting height of not more than 25
feet or the height of the building.
C.
Any other outdoor lighting, such as building and sidewalk illumination,
driveways with no adjacent parking and ornamental lighting, shall
be shown on the lighting plan in sufficient detail to allow determination
of the effects to adjacent properties, traffic safety and overhead
sky glow.
D.
To achieve these requirements, the intensity of such light sources,
the light shielding and similar characteristics shall be subject to
approval by the Board of Supervisors upon receipt of the recommendations
of the Township Engineer.
E.
The objective of these specifications is to minimize undesirable
off-premises effects. No light shall shine directly into windows or
onto streets and driveways in such manner as to interfere with or
distract driver vision.
A.
The minimum width of all sidewalks within or along the street right-of-way
shall be five feet. There shall be a minimum three-foot planting strip
between the curb and sidewalk. Combination sidewalks and curbs are
not permitted in residential areas.
B.
The grades and paving of the sidewalk shall be continuous across
driveways except in nonresidential and high-density residential developments
and in certain other cases where heavy traffic volume dictates other
treatment.
C.
Sidewalks shall be laterally pitched at a slope not less than 1/8
inch per foot towards the street to provide for adequate surface drainage.
D.
At corners, pedestrian street crossing points, and other pedestrian
access points, sidewalks shall be extended to the curbline with an
adequate apron area for anticipated pedestrian traffic and handicapped
ramps. Handicapped facilities, including on-site sidewalks for subdivisions
and land developments, shall meet the applicable regulations of the

required to install sidewalks along the frontage. All new proposed
streets shall have sidewalks on both sides of these streets. Properties
within the PIP, HI, MHC, and MPM Zoning Districts are exempt from
this provision.
Refer to § 191-58.
All curbs shall be constructed in accordance with the Falls
Township Design Details and Practices.[1]
A.
The lengths, widths and shapes of blocks shall be determined with
regard to:
B.
In general, all blocks in a subdivision shall have a minimum length
of at least 500 feet and a maximum length of 1,600 feet.
C.
Whenever practicable, blocks shall be of such width as to provide
two tiers of lots of the minimum size permitted under the applicable
zoning classification, except in the case of lots along a major highway
where the lot fronts on a proposed street.
D.
Pedestrian rights-of-way and bicycle paths not less than 10 feet
wide and with paving not less than four feet wide shall be required
where deemed essential to provide circulation or access to schools,
playgrounds, shopping centers, transportation and other community
facilities. The right-of-way for these walks shall be offered for
dedication to the Township.
A.
The size, shape and orientation of lots shall be appropriate for
the location of the subdivision and for the type of development and
use contemplated.
C.
All lots shall abut on a street except for multifamily developments,
where lots may gain access through driveways. Lots where the front
and rear property lines abut streets shall be avoided except in the
case of reverse frontage along major highways.
D.
In general, side lot lines shall be at right angles or radial to
the street lines.
E.
The depth and width of lots reserved or laid out for commercial and
industrial uses shall be adequate to provide for the off-street parking
generated by the use.
F.
Lots excessively deep in relation to width or lots excessively irregular
in shape are to be avoided.
G.
House numbers shall be assigned in accordance with Township requirements.
B.
No excavation shall be made with a cut face steeper in slope than
one horizontal to one vertical, except under one or more of the following
conditions:
(1)
The excavation is located so that a line having a slope of one horizontal
to one vertical and passing through any portion of the cut face will
be entirely inside of the property lines of the property in which
the excavation was made.
(2)
The material in which the excavation is made is sufficiently stable
to sustain a slope of steeper than one horizontal to one vertical,
and a written statement of an engineer to that effect is submitted
to the Township Engineer and approved by him. The statement shall
state that the site has been inspected and that the deviation from

Step III. Determine how land with resource restrictions is to
be protected.
(a)
Lands with natural resource restrictions may be preserved as
open space in accordance with Township ordinances. Where a minimum
open space ratio is required in a zoning district, lands with natural
resource restrictions may be used to meet this open space requirement.
(b)
Lands with natural resource restrictions which are required
to be protected by this section may occupy required side or rear yards,
provided that there is a minimum rear yard with a depth of not less
than 25 feet and minimum side yards with a width of not less than
10 feet which are free of lands with natural resource restrictions.
Lands with natural resource restrictions in side or rear yards shall
be protected from disturbance by means of a deed restriction.
