The purpose of this article is to regulate the
location, construction, maintenance and drainage of driveways and
other property within the rights-of-way of or connecting to streets,
for the purpose of security, safety, and reasonable access, preservation
of existing street operating capacity and condition, preservation
of surrounding land uses, provision of adequate drainage and economy
of maintenance.
For the purposes of this article, these terms
shall be defined as follows:
AVERAGE DAILY TRAFFIC
The total volume of vehicle trips expected on a street or
accessway during a specified period of time in whole days (more than

function of conveying, diverting, or removing surface water from the
street right-of-way.
DRIVEWAY
Every entrance or exit used by vehicular traffic to or from
properties abutting or connecting to a street. The term includes proposed
public and private streets, lanes, alleys, courts, and ways, including
acceleration and deceleration lanes and such drainage structures as
may be necessary for the proper construction and maintenance thereof.
EGRESS
The exit of vehicular traffic from abutting properties to
a highway.
FORM 408
The latest revision of highway construction specifications
issued by PennDOT.
IMPROVED AREA
The area within the street right-of-way which has been constructed
for roadway purposes, including roadbed, pavement, shoulders, slope,
sidewalks, drainage facilities and any other appurtenances.
INGRESS
Entrance of vehicular traffic to abutting properties from
a highway.
PAVEMENT EDGE
The edge of the main traveled portion of any street, exclusive
of shoulder.
PennDOT
The Pennsylvania Department of Transportation.
PERMIT
A street access permit issued by the Borough of Crafton pursuant
to this article.
PLANS
Drawings which show the location, character, and dimensions
of the proposed occupancy and related highway features, including
layouts, profiles, cross sections, drainage and other details.
ROADWAY
That portion of a street improved, designed, or ordinarily
used for vehicular travel, exclusive of the sidewalk or shoulder.
SHOULDER
The portion of the street, contiguous to the traffic lanes,
for accommodation of stopped vehicles, for emergency use, and for
lateral support of base and surface courses and pavements.
SHOULDER LINE
The intersection of the shoulder slope with the side slope
or ditch slope.
SIGHT DISTANCE
The distance required by a driver traveling at a given speed
to stop the vehicle after an object on the roadway becomes visible
to the driver as defined by PennDOT regulations.
STREET
The area, including the entire width between right-of-way
lines, over which the Borough, County of Allegheny, Commonwealth of
Pennsylvania or other political subdivision has assumed or has been
given jurisdiction for vehicular travel purposes.
STREET, ARTERIAL
A street owned, operated and maintained by the Commonwealth
of Pennsylvania or the County of Allegheny.
TRAFFIC CONTROL DEVICE
Any sign, signal, marking, or device placed or erected for
the purpose of regulating, warning, or guiding vehicular traffic or
pedestrians, or both.
VEHICLE
Every device in or by which any person or property is or
may be transported or drawn upon a street.
The applicant is responsible for submission
of four sets of plans which contain the following:
A. The land use proposed for the property.
B. A traffic control plan, if it is necessary to close
a lane to vehicular traffic in order to perform the permitted work.
C. A drainage control plan if, as a result of action
of applicant, there will be an increase in the flow of water onto
the street or into a street drainage facility. The plan must include
source of water, existing and proposed flow, existing and proposed
drainage pattern, and hydraulic computations demonstrating adequate
capacity in the drainage system to accept the additional flow. The
plan also shall comply with the Borough’s stormwater management
ordinance, if any.
D. A driveway access plan showing:
(1) Driveway width, radii and other points of curvature,
grades or profile view of drive, angle relative to the street and
surface material.
(2) Dimensions of any traffic islands/dividers to separate
traffic flow.
(3) Distance from proposed driveway to nearest intersecting
street, driveways on adjacent properties (both sides of street); adjacent
land uses; any traffic control devices.
(4) Sight distance in each direction from proposed the
driveway or street.
(5) The projected average daily traffic volume for the
driveway.
E. The number of parking spaces which will be served
by the proposed driveway.
F. A traffic impact study per the requirements of §
193-35.
No driveway will be approved unless all of the
following conditions are met:
A. General. The driveway must have safe sight distance,
not impair normal street movement, not result in excessive traffic
flow or congestion on streets and not create a safety hazard to the
public.
B. Location. The following standards shall apply:
(1) A driveway shall not be located at highway interchanges
or ramp areas so as to interfere with proper functioning. A driveway
shall not be located within 300 feet of any interstate highway interchange
or ramp access area.
(2) A driveway for a nonresidential use or a multifamily
use in excess of four units may only access an arterial street. Access
to a local street is prohibited.
(3) If the driveway is near a signalized intersection,
the permittee shall be required to pay the costs of any modifications
to the signals which are necessary to control traffic movements from
the driveway.
(4) If the property is a corner lot, the Borough may restrict
access to only one street.
(5) The Borough may require a permittee to locate the
driveway directly across from a street or driveway in order to avoid
any safety hazard.
C. Number. Borough Council will approve only one access
for a property.
D. Approach. The location and angle of access of the
driveway in relation to street intersection shall be such that a vehicle
entering or leaving a driveway can do so in orderly and safe manner
and with minimum interference to street traffic.
E. Design guidelines. The applicable requirements for
“minimum” and “low volume” driveways found
in PennDOT Regulations, 67 Pa. Code, § 1.8, as amended,
shall apply unless otherwise specified by the provisions of this article.
These requirements may be modified by the Borough to accommodate specific
site or street conditions in order to protect the safety and traffic
capacity of streets.
F. New or modified streets. New or modified streets and intersections, including, but not limited to, those requiring a traffic study pursuant to §
193-35, shall be designed for adequate traffic capacity defined as follows, unless otherwise approved by the Borough Engineer. All reference to levels of service (LOS) shall be as defined in the Highway Capacity Manual, Special Report 209, published by the Transportation Research Board.
(1) Traffic capacity LOS shall be based upon a future
design year which coincides with completion of the development and
PennDOT requirements.
(2) New unsignalized intersections or driveways which
intersect streets shall be designed for LOS C or better for each traffic
movement.
(3) New or modified (additional approach created) signalized
intersections shall be designed for LOS D or better for each traffic
movement. Existing intersections impacted by development traffic shall
maintain a minimum LOS D or, if future base LOS is E or F then degradation
in delays shall be mitigated. A future design year analysis without
development shall be completed for comparison purposes.
(4) Existing intersections impacted by development traffic
shall maintain a minimum LOS D for each traffic movement.
(5) Streets shall be designed for a minimum LOS C for
each traffic movement.
(6) Sight distance at driveways and new intersections
shall meet standards specified by PennDOT regulations.
