The following land subdivision and development
principles, standards and requirements shall be applied by the Township
Engineer, Planning Commission and Board in evaluating plans for proposed
subdivisions and land developments. These principles, standards and
requirements are the minimum provisions required by the Township for
the promotion of public health, safety, and general welfare.
[Amended 11-13-2019 by Ord. No. 320]
A. Single access streets shall not be approved wherever a through street connecting with other surrounding streets is feasible, unless such a connection is impractical or undesirable per the considerations outlined in §
175-29F.
B. Measurement of length. The length of a single access street shall
be measured along the center line of the street beginning at the center
line of the intersecting street and ending at the center of the cul-de-sac
bulb or the point at which a loop street connects back to itself.
C. A single access street, permanently designed as such, shall not exceed 1,000 feet in length, unless an emergency access is provided. Any required emergency access or fire apparatus access road shall be constructed in accordance with Chapter
90 of the Township Code (Fire Prevention).
D. An emergency access may also be required for a single access street that will not exceed 1,000 feet in length, whether permanently designed as such or as part of a phased development, if so required by the International Fire Code. Any required emergency access or fire apparatus access road shall be constructed in accordance with Chapter
90 of the Township Code (Fire Prevention).
E. Radius. Where permitted, a cul-de-sac shall be provided at the closed
end with a paved turnaround having a minimum radius to the outer pavement
edge or curb line of 50 feet with a minimum right-of-way radius of
60 feet.
F. Design and connection. The Board shall consider the existing or proposed
uses of adjoining lands, topography, drainage and other relevant site
characteristics affecting the design of a single access street or
through street. Unless a through street or future extension of a single
access street is impractical or undesirable based on the foregoing
considerations, or is precluded by the Board, which they shall have
the discretion to do, the right-of-way of a single access street shall
extend to the property line of the development tract and a right-of-way
for the same width as the street shall be carried to the property
line in such a way as to permit future extension of the street into
the adjoining tract. The future street extension shall be clearly
identified with signage.
G. Drainage. Drainage of a single access street shall be directed towards the open end of the cul-de-sac or loop end of the street, subject to the other design criteria specified in this chapter. All stormwater management and street drainage shall be in accordance with Chapter
170 of the Township Code (Stormwater Management).
H. Design. The design of single access streets shall be designed to
local or residential street standards, except that the centerline
grade shall not exceed 8% and the grade of the diameter of the turnaround
area shall not exceed 4%.
I. Temporary cul-de-sac. Where streets are temporarily terminated at
a property line or phase line with a temporary vehicular turnaround,
thus forming a cul-de-sac until such time as the street is extended,
all regulations pertaining to single access streets shall apply, except
that the temporary cartway turnaround need not be curbed unless so
directed by the Township Engineer. At such a time that the temporary
cul-de-sac has been extended and is no longer needed for the purposes
of a turnaround, the additional pavement from its radius shall be
removed and the ground restored to a vegetation condition.
[Amended 11-13-2019 by Ord. No. 320]
A. Streets in floodplains. Streets within a subdivision or land development
located entirely or partially within a designated Flood Hazard District
shall be prohibited unless the proposed street is intended to traverse
the floodplain area as part of an approved stream crossing by the
Pennsylvania Department of Environmental Protection or an appropriate
agency.
B. Obstructions. No fences, hedges, freestanding walls, plantings (except
approved street trees), or other obstructions shall be located or
remain within the right-of-way of a street.
C. Curbing is required for all new streets, regardless of roadway functional
classification.
D. Streetlights. Poles and standards for streetlights with appropriate
shielding and underground parkway cable service lines shall be furnished
and installed by the developer, spaced not more than 500 feet apart
and each providing with 0.2 footcandles of illumination. The Township
Engineer shall direct the type and location of streetlights to be
installed within the right-of-way areas.
E. Street trees. Deciduous street trees shall be planted by the developer within general alignment along the edge of the roadway, staggered along both sides, and spaced according to the type of tree. Street tree planting shall be required along all new or existing streets. Such trees must be properly balled and burlapped in accordance with accepted horticultural practice. This requirement is in addition to the landscaping requirements specified in §
175-41 and Chapter
200 of the Township Code (Zoning, Article

and similar needs.
C. Street construction. Construction of all streets and accessory installations
thereto, including but not limited to curbs, shoulders, bicycle infrastructure,
pedestrian infrastructure, and storm drainage structures, shall conform
to the minimum specifications of this chapter.
D. Exception to minimum widths. Short extensions (not exceeding 100 feet) of existing streets with lesser rights-of-way, travel lanes, shoulders, and/or parking lane widths than prescribed by Subsection
A may be permitted at the sole discretion of the Board; provided, however, that no section of the new right-of-way shall be less than 50 feet in width.
E. Improving existing streets. Where a subdivision or land development
abuts or contains an existing street with a right-of-way, travel lanes,
shoulders, parking lanes, and/or alignment which are insufficient
relative to the anticipated traffic demands of the development and/or
does not otherwise comply with the provisions of this chapter, the
Board shall require that the street be modified to comply with the
applicable sections of the East Whiteland Township ordinances.

grow which obscures the view within a clear sight triangle defined
by the following:
(a)
Above the height of 2.5 feet and below the height of 12 feet
measured from the centerline grades of the intersecting streets.
(b)
Within the area bounded by the centerline of intersecting streets
and a line joining points on these centerlines 75 feet from an intersection
of centerlines of such streets.
(3) All driveway and street intersections shall be designed and maintained
in such a manner that a clear view is obtained for vehicles entering
and exiting the intersection, according to the following:
(a)
The measurement and calculation of required sight distances
shall be in accordance with Pennsylvania Code Title 67, Chapter 441,
Access to and Occupancy of Highways by Driveways and Local Roads.
(b)
The PennDOT desirable sight distance requirements are typically
based on the posted speed limit. However, where the speed of traffic
may create a situation with unsafe sight distance, it may be necessary
to verify the 85th percentile speed of traffic at the recommendation
of the Township Engineer. If it is impossible to achieve the desirable
sight distances, then the minimum safe stopping sight distance values
may be used based on the 85th percentile speed of traffic, if necessary,
and subject to review by the Township Engineer.
(c)
If recommended by the Township Engineer, a sight distance profile
plan shall be prepared by a licensed professional engineer in Pennsylvania
to show at least the following for verification of adequate sight
distance and all associated improvements: existing roadway profile
(spot elevations at fifty-foot increments and twenty-five-foot increments
along vertical curves), proposed roadway profile, all sight line profiles
(six inches or more of sight line clearance above the finished grade),
proposed site grading and temporary grading easements.
