resubdivision or if a portion of the tract is not subdivided, adequate
street rights-of-way to serve further subdivision shall be provided
as necessary.
(5)
Where a subdivision or land development abuts or contains an existing
or proposed collector or arterial street, Borough Council shall require
dedication of additional rights-of-way to provide the minimum right-of-way
specified hereinafter, as well as rear service alleys, or such other
treatment as will provide protection for abutting properties, reduction
in the number of intersections with the major street and separation
of local and through traffic; provided, however, that deference to
the existing pattern of blocks and streets shall be demonstrated.
(6)
New half or partial streets shall not be permitted, except where
essential to reasonable development of a tract in conformance with
the other requirements and standards of this chapter and where, in
addition, dedication of the remaining part of the street has been
secured.

Definitions. As used in this section, the following terms shall have
the meanings indicated:
A study that is prepared in accordance with the Pennsylvania
Code, Title 67, Chapter 212, Official Traffic Control Devices, and
PennDOT Policies and Procedures for Transportation Impact Studies,
as such Code may be amended from time to time.
As described in the current Transportation Research Board's
Highway Capacity Manual, a qualitative measure of the operational
conditions within a vehicular traffic stream and their perceptions
by motorists. Six levels of service (A through F) are defined for
each type of facility, with LOS "A" representing the least congested
operating conditions and LOS "F" representing a breakdown in operating
conditions. Levels of service are defined in terms of average delay
per vehicle for signalized and unsignalized intersections. Level of
service drops are those future conditions that result in a negative
impact on intersection and/or approach lane level of service operations,
i.e. LOS D changes to a LOS E in future conditions.
The intersection of any arterial or collector street with
any other arterial or collector street as defined by PennDOT/NJDOT
Smart Transportation Guidebook, March 2008, PennDOT's Functional Classification
Map, the municipal roadway classification document or the equivalent
document of adjacent municipalities, where appropriate.
Transportation-related improvements which are generally not
contiguous with the property being developed and not required as an
on-site improvement but are found by the transportation impact study
to be necessary, partly or wholly, as a result of the proposed development.
All improvements on or adjacent to the development site in
the public right-of-way required to be constructed by the owner/developer
pursuant to any ordinance, resolution or requirement of the Borough
and PennDOT.
Transportation service for the general public provided by
a common carrier of passengers generally on a regular route basis,
or a private operator offering service to the public.
This procedure includes the average queue and maximum queue
of vehicles which will be observed in each traffic stream and intersection
approach, measured in both feet and vehicles. Various statistical
and/or computer models may be applied.
A meeting with PennDOT and/or the Borough Engineer to determine
the parameters of the transportation impact analysis required for
a PennDOT highway occupancy permit (HOP) or prior to the commencement
of the transportation impact study that is required pursuant to this
section to coordinate agreement on Borough conditions and expectations.
The study area shall be defined at the Borough/PennDOT scoping
meeting but, at a minimum, shall include all development site access
locations, any intersections immediately adjacent to the development
property as well as all major intersections within 1,000 feet of all
development access locations. Additional intersections may be added
per the scoping meeting. The study area shall also identify all transit
routes and transit stops within 1,000 feet of the proposed development/redevelopment
and the location of sidewalks and pedestrian crossings. Proposals
that will generate more than 1,000 average daily trips, without reduction
for pass-by or internal capture, shall expand the study area to include
major intersections within a one-half-mile radius of the development
access locations. All intersections identified in the study area shall
be examined, even if the intersections are located outside of the
Borough.
A one-way trip into or out of the site, and not what is commonly
referred to as a "round-trip."
The total number of trips to and from a study site per unit
of land use, as measured by the most current edition of the Institute
of Transportation Engineers (ITE) "Trip Generation Manual." Upon approval
by the Borough Engineer, alternative sources may be accepted.
This procedure compares the volume of a roadway or intersection
approach to its capacity (maximum number of vehicles that can pass
a given point during a given time period.) The procedures described
in the 2010 Highway Capacity Manual (latest edition), Highway Research
Board Special Report 209, shall be followed.
A series of tests which identify the minimum vehicular traffic
or pedestrian volumes or other criteria necessary for installation
of a traffic signal. The warrant criteria are available in the current
Manual of Uniform Traffic Control Devices (MUTCD), or PennDOT's Traffic
Engineering Manual (Publication 46).
E.
Scoping meeting. A scoping meeting shall be required to ensure that
the parameters used in the transportation impact study accurately
reflect Borough conditions and expectations. The applicant should
contact the Borough Engineer to confirm the scope of the scoping meeting
prior to any submission. The scoping meeting shall address the number
and locations of proposed access points, project schedule and phasing,
study area and additional intersections to be included in the analysis,
specific ITE Trip Generation land use codes, pass-by volumes, modal
splits, any trip adjustments to be used, and other area developments
and programmed roadway improvements to be included in the future conditions
analysis as well as potential opportunities to implement transportation
demand management (TDM) activities and improve upon existing pedestrian
facilities. Agreement on all scoping parameters shall be obtained
prior to initiation of the transportation impact study. The scoping
meeting may be held in conjunction with the PennDOT scoping meeting.
In addition, SEPTA shall be notified and invited to attend the scoping
meeting to discuss potential transit improvement opportunities.

feet range of proposed development and pedestrian accessible routes
(ramps, crosswalks, and availability of paths) shall be discussed
as applicable.
(c)
Note any characteristics of the development, the general site
or study area that may cause particular trip generation, distribution
or modal split modifications.
(d)
Note development features that are planned to reduce trip generation
rates and document transportation demand management (TDM) assumptions.
Noted TDM practices must be included in the conditions of approval
if listed in the transportation impact study and shall be discussed
during the municipal scoping meeting.
(5)
Analysis of impact.
(a)
The total future traffic shall be calculated and shall consist
of the existing traffic volumes expanded to the project completion
year using an annual background growth factor plus the development-generated
traffic and the traffic generated by other developments in the study
area as identified at the PennDOT or scoping meeting. A minimum of
two years' projection shall be assumed for all projects regardless
of the anticipated completion year.
(b)
The annual background growth factor for overall traffic volumes
shall be determined using PennDOT's growth factors calculations unless
enough local ADT volume data is available to establish more accurate
average traffic volume changes over the past five years. The background
growth factor shall be established at the scoping meeting. The background
growth rate shall be applied to the current ADT and turning movement
volumes to forecast background traffic volumes for the development
opening year and any successive phase completions. A minimum of two
years' projection shall be assumed for all projects regardless of
the anticipated completion year. All assumptions used to revise trip
distribution shall be provided, including but not limited to other
major developments that may change current traffic patterns.
(c)
Future transportation conditions shall be analyzed using the
same techniques as used for the existing transportation conditions.
Future conditions without the proposed development traffic ("future
without") shall be provided for all study area intersections and shall
include background traffic growth and traffic from other local proposed/approved
developments as agreed to at the scoping meeting. Only those roadway
improvements that are programmed, with obligated funds, to be completed
prior to the opening year of the proposed development shall be included
in the "future without" analysis. Diagrams illustrating LOS, v/c ratios
and average vehicle delay in seconds shall be provided for each study
area intersection/turning movement for "future without" conditions
and include a table identifying the volume/capacity ratios, levels
of service, average vehicle delays, queue lengths by approach and
intersection.
(d)
A second future conditions analysis shall be conducted that
includes the proposed development/redevelopment traffic ("future with").
Roadway improvements proposed to be constructed by the developer prior
to the opening date of the development shall be incorporated into
the analysis. Diagrams illustrating LOS, v/c ratios and average vehicle
delay in seconds shall be provided for each study area intersection/turning
movement for total "future with" traffic conditions.
(e)
A table shall be provided illustrating the existing "future
without" and "future with" conditions for all intersections within
the study area, by lane group and identifying the LOS, delay in seconds,
v/c ratios, and queues for each lane group. The table should note
any changes to the roadway that have been included in the "future
without" and "future with" analyses. Queue length studies for unsignalized
intersections shall also be conducted for existing, "future without"
and "future with" conditions and displayed in graphics and/or a table
and noting "future without" and "future with" improvements and include
a table identifying the volume/capacity ratios, levels of service,
average vehicle delays, queue lengths by approach and intersection.
(f)
All analyses shall include a.m., p.m. and Saturday (if required)
peak roadway hour(s) and peak development-generated hour(s), if different
from the roadway peaks, for all roadways and intersections in the
study area. All access points and pedestrian crossings shall be examined
as to the appropriateness of installing traffic signals or other traffic
control measures based on the current PennDOT approved edition of
the Manual of Uniform Traffic Control Devices. Roundabouts may be
considered as an alternative to additional traffic signals, if approved
by both PennDOT and the Borough. In addition, pedestrian accessibility
routes shall be analyzed for 1,000 feet in all directions to ensure
adequate pedestrian facilities are available for pedestrian and transit
users. The Borough may request the applicant provide bicycle improvements
including but not limited to bicycle racks, bicycle route designation
(signage and pavement markings) or other improvements to encourage
the use of bicycles.
(6)
Sight distance analysis. Sight distance measurements shall be
performed at any proposed driveway and/or existing driveway to determine
sufficient sight distance to the left and right of the driveway. Sight
distances shall be compared to the desirable sight distance standards
as specified in the Pennsylvania Code, Title 67, Chapter 441, Access
to and Occupancy of Highways by Driveways and Local Roads, April 2006.
When desirable sight distance cannot be achieved, sight distances
shall also be compared to PennDOT's safe stopping sight distance (SSSD)
requirements as specified in A Policy on Geometric Design of Highways
and Streets (6th Edition), of the American Association of State Highway
and Transportation Officials (ASSHTO), Chapter III, Elements of Design,
2011.
(7)
Conclusions and recommendations.
(a)
Future levels of service (LOS), average vehicle delay and v/c
ratios shall be listed in tabular form for all intersections and turning
movements. Signalized intersections showing a level of service E or
F, and v/c ratios equal to or greater than 1.0 shall be considered
deficient and unsignalized intersections showing a level of service
D, E or F shall be considered deficient.
(b)
Level of service drops or increase in delay by 10 seconds for
any studied period shall be identified for both "future without" and
"future with" conditions. Level of service drops shall be identified
by each approach lane group.
(c)
Specific recommendations for mitigation of level of service
drops, increase in intersection delay of 10 seconds or more, or level
of service drops or increase in critical movement delay of 10 seconds
or more in the "future with" analysis shall be listed and shall include:
internal circulation design, site access location and design, external
roadway intersection design and improvements including the potential
for construction of roundabouts, traffic signal installation and operation
including signal timing, transit design improvements, and any pedestrian
or bicycle route improvements needed to support nonvehicular mobility
associated with the development proposal.
(d)
All identified improvements shall be illustrated and overlain
on aerial photography to show the extent of the construction and right
of way impacts and include a cost estimate for improvements. Proposed
improvements shall consider all roadway users including motorized
and nonmotorized vehicles, bicycles, pedestrians and transit.
(e)
Signal timing revisions and/or signal equipment upgrades shall
be evaluated for any intersection with a level of service E or F,
but a volume/capacity (v/c) ratio less than 1.0. Traffic signal warrants
for signalization or other traffic control measures shall be examined
for unsignalized intersections with levels of service D, E or F based
on the current Manual of Uniform Traffic Control Devices or PennDOT
Traffic Engineering Manual.
(f)
Existing and/or future public transit service shall also be
addressed and any transportation demand management techniques proposed
with the development shall be identified. A listing of all actions
to be taken to encourage public transit usage or other transportation
demand management techniques for development-generated trips, and/or
improvement to existing service, if applicable, shall be included.
Any proposed transit service improvements shall be coordinated with
SEPTA or the appropriate local transit provider and should conform
to SEPTA's current bus stop design guidelines.
(g)
All proposed transportation system improvements shall be consistent
with Borough comprehensive planning or other planning documents referencing
overall transportation mobility and/or transit services.
(8)
Implementation of recommendations. The Borough may have an independent
review done of the applicant's transportation impact study, at the
applicant's expense, to make a final determination of the improvements
that must be implemented. The Planning Commission and Borough Council
shall review the transportation impact study to analyze its adequacy
in solving any traffic problems that will occur due to the land development
or subdivision. The applicant shall be required to implement the on-site
transportation improvements necessary to mitigate the "future with"
deficient traffic conditions as noted in the transportation impact
study unless modified or waived by Borough Council. Borough Council
may determine that certain other improvements on and/or adjacent to
the site and within the study area are necessary requirements for
land development or subdivision plan approval and may attach these
as conditions to the approval if permitted by law. If the Borough
Council determines that such additional improvements are necessary,
the applicant shall have the opportunity to submit alternative improvement
designs to obtain plan approval.
(9)
Additional coordination with PennDOT may be necessary to ensure
compatibility between the proposed transportation improvements and
highway occupancy permit requirements.
(10)
All communications with PennDOT regarding the highway occupancy
permitting process or other transportation-related issues associated
with the proposed development/redevelopment shall be copied to the
Borough.
(11)
The Borough shall be included in the PennDOT ePermitting process
as an applicant on the highway occupancy permitting application through
the PennDOT Business Partner Identification Number 4457 for the Borough
of West Chester.
A.
Permanent concrete monuments shall be set at all corners and angle
points of the boundaries of the original tract to be subdivided and
at such intermediate points as may be required by the Borough.
B.
All lot corner markers shall be so located that individual properties
may be readily ascertained after development of the subdivision. Markers
shall be set in the ground at finished grade. No occupancy permits
will be issued for buildings until markers are in place. No public
improvements will be accepted until all monuments are in place.
Any application for approval of a mobile home park shall be subject to provisions of Chapter 112 of the Borough Code, titled "Zoning," as they relate to single-family dwellings.
