A.
All uses in all districts shall be subject to the
following standards of operation.
B.
Land uses requiring traffic studies:
(1)
Applicability. To assure that no major traffic generating developments
are constructed without benefit of a traffic study, such studies shall
be conducted for all nonresidential developments anticipated to generate
20 or more p.m. peak-hour trips, or a thirty-percent increase in existing
building coverage, in any district, and all residential developments
of 10 or more single-family dwellings or 16 or more multifamily dwellings
in any residential, special or conservation districts.
[Amended 10-20-2015 by Ord. No. 541]
(2)
Study requirements.
(a)
Inventory. The study shall examine the Borough's
street and highway network and make a preliminary determination as
to the streets and intersections likely to be affected by the proposed
development. For purposes of this finding, the expected addition of
as many as 20 vehicles per hour traveling in any direction along the
affected street or approach to an intersection during either the a.m.
or p.m. peak hour shall be deemed to be a significant effect. For
these significantly affected streets and roadways, an inventory of
pavement widths and conditions, travel speeds, traffic flow composition,
twenty-four-hour traffic flows along the streets and a.m. and p.m.
peak street traffic hour period (two hours each) turning movement
counts at the intersections shall be obtained. The physical inventory
data shall include locations and lengths of restricted sight distances,
restricted lateral clearances, traffic and parking regulatory controls
and pertinent observations concerning traffic operating conditions.
Traffic flow data shall be adjusted to represent the expected flow
on an average annual day through application of appropriate PennDOT
adjustment factors.
(b)
The most current available three-year history
of accidents as filed with the police department shall be obtained
for each affected intersection. Collision diagrams shall be prepared
for any high accident location (five or more per year) along the affected
street system.
(3)
Traffic flow analyses.
(a)
For each study intersection, a level-of-service
capacity study, using the techniques for signalized or unsignalized
intersections as described in the current edition of the Transportation
Research Board's Highway Capacity Manual shall be completed. For these
purposes, intersections shall be treated as if they are signalized
with an optimum timing plan.
(b)
Any section of the affected street system which
is carrying 300 or more vehicles per hour on a two-lane section, also
shall be subjected to the appropriate capacity study.
(c)
The presentation of the findings of these studies
shall include findings on what improvements, if any, are indicated
as being needed under existing conditions, and their relationship
to the improvements and priorities described in Edgeworth Borough's
Zoning and Subdivision and Land Development regulations. These findings
shall include an examination of the volume and accident warrants for
signalization in the Manual on Uniform Traffic Control Devices, as
they may apply to any of the unsignalized study intersections which
have need for immediate signalization.
(4)
Trip generation.
(a)
The expected number of trips to be generated
by the proposed development shall be estimated for the a.m. and p.m.
peak hours and for a twenty-four-hour period by use of the appropriate
trip generation factors in the current edition of Trip Generation,
published by the Institute of Transportation Engineers. The expected
numbers of vehicles to be generated to and from the site may be adjusted
downward by the estimated proportion of passersby in the existing
flow which will be intercepted by the new development. This adjustment
shall be reasonable and, wherever possible, based on actual survey
results.
(b)
In similar fashion, for complex multiuse sites,
the number of off-site movements may be adjusted downward by estimating
the synergistic absorption of movements between different generators
on-site. Again, this adjustment shall be reasonable and defendable.
(5)
Trip distribution.
(a)
The expected distribution of the generated movements
throughout the defined study area shall be estimated for the a.m.
and p.m. peak hours and for a twenty-four-hour period. This distribution
shall be based on the best available information as to the likely
movement directions to and from the site. The directional distribution
and magnitudes of existing traffic flows may be employed for this
purpose as well as origin and destination data for the area which
can be obtained from the Southwestern Pennsylvania Commission (SPC).
(b)
The distributed flows shall be added to the
existing volumes and turning movements for the a.m. and p.m. peak
hour and for a twenty-four-hour period. These shall then be the estimated
flows which are expected to prevail upon completion of the development.
(6)
Staged development.
(a)
For projects which will take several years to
complete, the projected overall development plan shall be presented,
and specific portions for which permits are sought shall be sufficiently
detailed to make the above-described studies. The timetable for completion
of each section for which permits are sought shall be specified and
the study shall be broken into phases in accordance with this schedule.
(b)
The trips for the first section shall be added
to the existing flows for a current year estimate and the trips for
subsequent sections shall be added to the estimated volumes expected
on the street system for each appropriate year plus the generated
trips added for each prior section. It is to be noted that this procedure
covers only those sections for which permits are being sought and
does not constitute any obligation or assurance concerning future
sections of the development on the part of Edgeworth Borough or the
developer.
(7)
Adjustment of study area. If the above studies shall
disclose that there are parts of the street system or intersection
approaches beyond those originally examined which will be affected
in either peak hour or to the extent of 20 or more added vehicles,
the study area shall be extended and necessary inventory data gathered
to incorporate them into the study process. Conversely, if any are
found to fall below that threshold, they may be dropped from further
consideration.
(8)
Impact analyses.
(a)
For each established study location, appropriate
level-of-service capacity studies shall be made to ascertain the expected
impact on the traffic flow. If the expected level of service is "D"
or less, appropriate corrective measures shall be identified and described.
If the prescribed corrective measures are already identified in the
Edgeworth Borough Zoning or Subdivision and Land Development regulations,
that fact shall be noted. If the expected level of service has changed
from "D" to "E" or "F" as a result of the added traffic, that fact
shall also be noted.
(b)
For each identified high hazard location, and
for each study intersection with five or more accidents per year,
and studies shall be presented of the extent to which these may be
due to existing physical or control conditions and the extent to which
the added traffic may exacerbate the condition. Appropriate corrective
measures, along with their relationship to the minimum levels of service
established by Edgeworth Borough, shall be identified and described.
(c)
If the developer desires to volunteer to undertake
any of the identified corrective measures at his cost in the interest
of timely completion in respect to his project, they should be identified
in the impact report.
(9)
Site access.
(a)
The location and design details of all proposed
site access points shall be presented along with estimates of expected
peak-hour entrance and exit flows and turning movements. Sight distances
along the access streets at the access points shall be stated and
any proposed modifications or controls of the access street which
the developer proposed to build or install shall be described. An
analysis of the expected level of hazard which may exist at the access
points when in operation shall be presented.
(b)
In the case of multistage, multiyear projects,
the overall development project shall identify the anticipated final
access point layout, but only those access points being provided to
handle the development traffic for those sections which permits are
requested, need be subjected to this detailed analysis.
(10)
Study presentation. Six copies of the completed
traffic study shall be submitted at the time applications for approvals
are filed. The professional person(s) responsible for the content
of the report shall be available to present and defend the report
at subsequent technical review meetings and formal hearings.
The developer shall determine the presence of
environmental or natural features on the site and shall meet the following
standards of environmental protection. Site alterations, regrading,
filling or clearing of vegetation prior to approval of the plans for
development shall be a violation of this chapter.
A.
Forest. No more than 50% of any forest may be cleared
or developed. The remaining 50% shall be maintained as permanent open
space.
B.
Ponds, watercourses or wetlands. These areas shall
be left as permanent open space. No development, filling, piping or
diverting shall be permitted except for required roads.
C.
Stormwater drainage and management. Stormwater drainage
and management plans shall be developed for each subdivision or land
development plan at both the preliminary and final plan submittal
stage, and for each individual lot for which improvements are proposed,
in accordance with the following:
(1)
Where additional impervious surface coverage will
result from the installation of improvements to any lot, tract or
parcel, whether occurring singularly or as a consolidation of lots,
stormwater shall be managed to discharge the postdevelopment rate
of runoff at 90% of the predevelopment rate.
D.
Soil erosion and sedimentation. All developments shall
protect streams and ponds from sedimentation damage and control erosion
in accordance with the Clean Streams Law, P.L. 1987, Chapter 102,[1] and the Soil Erosion and Sedimentation Control Manual, Pennsylvania Department of Environmental Protection, May 1, 1981, and in accordance with § 113-30 of Chapter 113, Subdivision and Land Development, as amended. In addition, all commercial or industrial developments of any size shall submit a soil erosion and sedimentation plan as part of the required final land development submittals.
