A.
Driveways shall be constructed in accordance with the Standard Details.
B.
All driveways and related improvements within a Township road right-of-way shall be constructed and located in such a manner so as not to impair drainage or maintenance within said road right-of-way area, alter the stability of a roadway subgrade, materially change the drainage of adjacent areas, interfere with the traveling public, present a hazard to the free movement of normal street traffic or create areas of undue traffic congestion on the Township road. All surface runoff shall be detained on the applicant's property, and in no case shall the applicant direct or allow such surface runoff to exceed the requirements of Chapter 388, Stormwater Management, of the Township's Code.
C.
Sight distance requirements. Driveway entrances shall be located
so as to provide reasonable and safe sight distances to the operator
of a vehicle departing from a driveway onto a Township road. The location
of all driveways is subject to the approval of the Township Engineer
or his designee. A clear sight triangle shall be provided at all intersections
of a driveway with a Township road. The clear sight triangle shall
conform to AASHTO standards based upon approach grades and posted
speed limits.[1]
D.
Repairs. Any repairs to an existing driveway within the Township
road right-of-way, under this chapter, shall not change the original
design and specifications for the driveway, unless the new design
and specifications are first submitted to the Township for approval
and are approved by the Township Engineer or his designee. The Township
Engineer or his designee shall require the payment of the application
and inspection fees established by the Board of Supervisors.
(1)
The Township Engineer or his designee may require the replacement
of existing improvements (including but not limited to depressed curb,
sidewalk, and storm sewer pipes) located within the area of proposed
work that are deemed deficient or defective by the Township Engineer
or his designee with new improvements that meet the requirements established
elsewhere within these public improvements specifications.
(2)
In a case where an existing driveway is proposed to be resurfaced
with asphalt within the Township road right-of-way, the paving transition
of the driveway into the Township road shall be smooth and even.
E.
Pavement requirements. New (proposed) driveways shall be paved from
the edge of the Township road (including roads intended to be dedicated
to the Township under the auspices of an approved subdivision and/or
land development plan) paving to, at a minimum, the road right-of-way
line. The minimum paving cross section shall consist of 1.5 inches
9 mm superpave wearing course over three inches 25.0 mm superpave
base course and four inches of PADOT 2A modified aggregate. Where
sidewalks cross driveways and reinforced concrete aprons are used,
such aprons, as well as the sidewalks adjacent thereto, shall consist
of at least six inches of reinforced concrete on four inches of PADOT
2A modified aggregate. Where sidewalks cross driveways and asphalt
aprons are used, the asphalt cross section shall be as specified above
for proposed driveways, and the sidewalks adjacent to the apron shall
be as previously specified.
F.
Dimensional requirements. The minimum driveway width shall be 10
feet, and the minimum driveway radius shall be five feet.
H.
The entire driveway entrance shall be located within the frontage
of the property that is to be served by the driveway.
I.
Corner lot driveway requirements.
(1)
All driveways on corner lots or lots that have frontage on more
than one road shall be located on the road that is anticipated to
have the least traffic or on the road designed by the Township Engineer
or his designee.
(2)
All driveways on corner lots and on lots facing a T-intersection
shall maintain a minimum distance, measured from the center line of
the intersecting road to the center line of the driveway, of 100 feet,
and in the case of townhouses, 64 feet. Modification of these requirements
may be approved by the Township Engineer.
J.
Common access driveways. Common access driveways are not encouraged
and shall only be permitted when approved by the Township Engineer.
The Township Engineer may require driveway materials of construction
and dimensions beyond those specified for typical driveways and may
further require an access and maintenance agreement among the involved
property owners.
K.
Secondary driveways. No single lot or parcel of land shall have more
than one driveway, except where the frontage exceeds 300 feet in length
or where the frontage is along a divided highway. In such instances,
a second driveway is permissible.
L.
Drainage requirements. Unless curb exists along the Township road,
the intersection of all driveways with the paved edge of a Township
road shall be constructed by incorporating a drainage gutter across
the width of the driveway in accordance with the Standard Details.
An HDPE or RCP pipe, 15 inches minimum diameter, may be used in lieu
of the drainage gutter if approved by the Township Engineer.
M.
Approach. The angle of a driveway as it intersects a street shall
be such that a vehicle entering the driveway may do so in an orderly
and safe manner with a minimum of interference to other street traffic
and, in the case of driveways on lots of 1/2 acre or more, such that
a vehicle leaving the driveway may enter safely into the lane of traffic
moving in the desired direction. Driveways shall intersect streets
as nearly as possible at right angles, and in no case at an angle
of less than 75° or more than 105°.
Driveways for nonresidential uses shall also meet the following
requirements, in addition to the previously identified requirements:
A.
Nonresidential driveways shall be designed to meet the requirements
set forth in Chapter 441 of Title 67 of the Pennsylvania Code.
B.
Nonresidential driveways shall be paved with 1 1/2 inches of
superpave 9.5 mm PG 64-22 wearing course, 4 1/2 inches of superpave
25.0 mm base course and six inches of PADOT No. 2A compacted coarse
aggregate subbase.
C.
Nonresidential driveways shall be provided with curb returns of appropriate
radius in accordance with PADOT standards, rather than depressed curbs.
D.
Nonresidential driveways shall be constructed with a 2% minimum crown
or cross-slope.
E.
Nonresidential driveways shall have minimum radii of 60 feet.
