and constructed in accordance with the Salisbury Township Construction
Code Standards.
(3)
Properly super-elevated curves (banked curves) shall be provided
on arterial and collector streets and when required by the Township
Engineer.
C. Grading Beyond Right-of-Way.
(1)
The subdivider or developer may be required to grade beyond
the right-of- way line in order to provide continuous slope from the
proposed right-of-way line elevation to the existing elevation of
the abutting property.
(2)
Such grading beyond the right-of-way shall maintain the original
drainage patterns except where stormwater runoff designs dictate or
warrant improvement or alteration of the original slope and contours.
(3)
Approved plans, either preliminary or final, showing proposed
grading, shall contain a note on the plan, which note shall state
that the grading proposed on the plan shall be maintained, and that
the note constitutes a covenant running with the land enforceable
by the Township and binding upon the developer, his heirs, executors,
administrators, successors-in-title, successors, and/or assigns, unless
altered by written permission from the Township.
(4)
In areas of earth excavation or earth fill, such grading shall
be done to the maximum extent practical at a slope of three feet horizontal
to one foot vertical. Steeper slopes shall only be allowed after review
and recommendation by the Township Engineer and permanent ground stabilization
shall be accomplished with a maintenance free planting.
D. Drainage of Streets.
(1)
Parallel and cross drainage facilities shall be properly located,
designed and installed to maintain proper drainage of the completed
streets.
(2)
Proper design may require the use of curb and gutter or paved drainage swales to prevent erosion. Drainage facilities shall be designed in accordance with requirements of §
22-1010.
(3)
Open pipe ends must be fitted with concrete end walls or prefabricated
end sections and with protective safety gratings.
(4)
No open pipes shall be allowed to end within the Township street
right-of-way, except in cases where new or existing driveways must
cross deep swales adjacent to new or existing Township roads. In the
case of these exceptions to the standard, the pipe shall be located
as far off the edge of pavement as possible, and at least 20 feet
from the road center line.
(5)
Energy dissipaters shall be placed at the outlets of all pipes
where flow velocities exceed the maximum permitted for the proposed
channel lining. All pipe discharge facilities shall be designed in
accordance with current Township Construction Code standards.
(6)
Consideration shall be given for subgrade drainage of those
soils subject to frost heave. Design of the road bed in such locations
may require parallel drainage facilities and/or underdrains to properly
stabilize the subgrade. The Township may require that such drainage
facilities be provided. The requirement and design of such subgrade
drainage facilities shall be subject to the recommendation, review
and approval of the Township Engineer.
11. Required Traffic Improvements.
A. Purpose. In recognition of the provisions of the Article V-A and § 503(2)(ii)
and 503(3) of the MPC, this section is primarily intended to ensure
that streets bordering a subdivision or land development are coordinated
and of such widths and grades and in such locations as deemed necessary
to accommodate prospective traffic and to facilitate fire protection
and to ensure that the access into and out of subdivisions and land
developments is sufficiently safe.
B. Process. Determinations under this Subsection
11 shall be made by the Township, after considering any recommendations of the Planning Commission, the Township Engineer, the applicant, the applicant's professional representatives, any comments from PennDOT that may be provided regarding a state road and any professional traffic studies that may have been submitted.
C. On-Site Traffic Improvements. An applicant for a subdivision or land
development shall be required to pay for and install, at his own expense,
all requested on-site improvements as defined in Article V-A, § 502-A
of the MPC. On-site improvements may include, but are not limited
to, a new traffic signal or traffic control devices, the improvement
of an abutting roadway or intersection, realignment of a curve in
an abutting roadway or the widening of an abutting cartway or right-of-way.
D. Widening of Abutting Street. An applicant for any land development
or subdivision shall be required to widen the cartway and any shoulders
of abutting streets to Township standards (or other specifications
approved by the Board of Commissioners or PennDOT) and to a width
determined to be adequate by the Township as reasonably related to,
and necessitated by, the land development or subdivision for the public
health, safety, and welfare. The applicant shall only be responsible
for improvements from the center line of the street right-of-way inward
toward the project's lot lines, unless the Township determines
that improvements on the other side of the center line are reasonably
related to, and necessitated by the subdivision or land development
for ingress and egress and are essential for public safety.
12. Maintenance of Accessways. Where accessways are permitted, the developer
shall enter into a legally binding agreement (which agreement shall
be recorded in the Office of the Recorder of Deeds of Lehigh County)
specifying who shall be responsible for the improvement and perpetual
maintenance of any accessway as a condition of final plan approval.
13. Street Names.
A. A proposed street which is obviously in alignment with an existing
named street shall bear the name of the existing street.
B. In no case shall the name of a proposed street duplicate or be similar with an existing street name in the Township, except as required in §
22-1004, Subsection 13.A, irrespective of the use of the suffix street, road, avenue, boulevard, drive, way, place, court, lane, etc.
C. All street names shall be subject to the approval of the Township.

include a fifteen-foot deep planting strip along one of the streets
with access across this strip clearly prohibited by notes on any approved
plan.
(1)
Any fencing in the rear of such lots shall be placed on the
inner perimeter of such plantings.
(2)
This planting strip shall be placed along the street that the
Township determines will eventually serve the most through-traffic.

2. On-Lot Water System.
A. Where individual on-site water supply system(s) are to be utilized,
each lot so served shall be of a size and shape to allow the safe
location of such a system.
B. Where individual on-site water supply system(s) are to be utilized,
it is required that the subdivider or land developer provide at least
one test well for each 10 proposed dwelling units. Such wells shall
be drilled, cased, and grout-sealed into bedrock at least 50 feet
deep and shall have a production capacity of at least five gallons
per minute (gpm) per proposed dwelling unit of safe, potable water
meeting all maximum contaminant level (MCL) parameters of the PA DEP
new source drinking water standards as certified by the PA DEP or
a PA DEP approved laboratory. The well(s) and appurtenances shall
be located, drilled and installed in accordance with all applicable
requirements of the PA DEP. The contaminant, its test result, and
its established MCL for a community water system as described by the
PA DEP, shall be included on the recorded plan for any contaminant
which exceeds the established MCL. The test well(s) should be located
such that they are remote from each other, and such that they may
be utilized as permanent wells by future lot owners. The proposed
location(s) shall be subject to review by the Township Engineer. During
the drilling operation, straw bales and filter fabric shall be provided,
placed and properly anchored as necessary for temporary control of
silt-laden runoff and soil erosion. The test well(s) shall be subjected
to drawdown tests (simultaneously if more than one test well) for
a period of at least eight hours to confirm that the capacity is adequate
and to determine the effects on existing wells adjacent to the land
development. The pumping rate shall be constant throughout the duration
of the test and shall be based on a minimum of five gpm per proposed
dwelling unit, with the resultant total rate distributed approximately
evenly over the total number of test wells. The test well(s), along
with existing wells adjacent to the land development, shall be monitored
for drawdown. The location(s) of the existing well(s) which are to
be monitored shall be subject to review by the Township Engineer and
shall depend on site-specific conditions such as topography, soils,
types, geology, test well pumping rate, etc. The pumping rate and
water level of each test well, and the water level of each monitor
well, shall be logged according to the following schedule.

1. General Requirements.
A. Stormwater projects proposing less than 10,000 square feet of increased
runoff producing surfaces, including but not limited to buildings
and pavement and other impervious surfaces, compacted stone and paver
surfaces, and change in ground cover due to tree removal, are required
to provide a drainage plan and narrative meeting these sections for
Township review and approval.
B. Stormwater projects proposing 10,000 square feet or more of increased
runoff producing surfaces, including but not limited to buildings
and pavement and other impervious surfaces, compacted stone and paver
surfaces, and change in ground cover due to tree removal, are required
to provide a drainage plan and narrative meeting these sections for
Township and Lehigh Valley Planning Commission review and approval
for Act 167 compliance.
C. All development projects creating increased runoff producing surfaces
in excess of 2,000 square feet shall be required to attenuate the
increased runoff from the site for the two year return period storm
and meet the discharge requirements of the Act 167 Plan for the ten-year,
twenty-five-year and 100-year storms.
D. The storm drainage plan and narrative shall analyze the impact of
any increased storm water runoff discharged from the site for each
storm, both rate and volume, on downstream property owners using Township
and County Conservation District approved criteria. If the drainage
plan and narrative indicates the proposed development will aggravate
or worsen existing downstream conditions on downstream properties,
the developer shall either revise the drainage plan and narrative
with detention or infiltration facilities to attenuate the increased
runoff or obtain written permission via a drainage easement approved
by the Township to allow the additional runoff.
E. Storm sewers shall tie into reasonably accessible existing storm
sewers if required by the Township and if adequate capacity exists
in the existing system. When the development project proposes connecting
to any Township storm drainage system, the storm drainage plan and
narrative shall analyze the existing storm drainage system to verify
sufficient capacity in the existing system to handle the increased
flow to the system.
F. Storm drainage facilities shall be designed and provided to permit
unimpeded flow of natural watercourses and proposed stormwater improvements
without damage to persons or property.
G. Storm drainage facilities should be designed not only to handle the
anticipated peak discharge from the property being subdivided or developed,
but also to accommodate or receive the runoff that will occur from
properties at higher elevations (i.e., which drain through the property
being subdivided or developed).
H. Storm sewers shall tie into reasonably accessible existing storm
sewers if required by the Township and if adequate capacity exists
in the existing system.
I. All lots shall be laid out and graded to prevent cross lot drainage
and to provide positive drainage away from proposed building areas
and on-site sewage disposal facilities. A note to this effect shall
be placed on all plans to be recorded.
J. An adequate storm sewerage system consisting of inlets and other
underground drainage structures with approved outlets shall be constructed
where the proper collection of stormwater runoff and the prevention
of erosion cannot be accomplished satisfactorily by surface drainage
facilities.
K. Outlets shall be approved by the Township:
(1)
Natural drainage shall be maintained where reasonable.
(2)
The existing points of natural drainage discharge onto adjacent
property shall not be altered nor shall the rate or discharge characteristics
(sheet flow, channelization, etc.) of runoff be altered or increased
because of development without the written approval of all affected
landowners.
(3)
No stormwater runoff or natural drainage water shall be so diverted
as to overload drainage systems, or create flooding or the need for
additional drainage structures on other private properties or public
lands, without provisions deemed acceptable to the Township being
made by the developer to satisfactorily handle such conditions.
L. Storm sewerage systems shall not be combined with sanitary sewerage
systems.
M. Design of storm drainage collection systems shall be based at a minimum
upon twenty-five-year return frequency storm flows and shall be prepared
and sealed by a professional engineer licensed in the Commonwealth
of Pennsylvania. Complete sealed calculations shall be submitted to
the Township for review by the Township Engineer (see Appendix D).
All designs must be approved by the Township Engineer.
2. Specific Requirements (refer to Appendix D for design criteria).
A. Collection Systems.

Stormwater runoff from streets shall not be permitted to flow
across building lots but shall be collected with the street right-of-way
and discharged in a controlled manner.
(2)
Inlets shall be placed at all low points, at points at points
where the flow in gutters exceeds three inches, and at a distance
appropriate to collect peak runoff expected from a twenty-five-year
minimum return frequency storm, Inlets or manholes shall be placed,
as appropriate, at points of change in the horizontal or vertical
directions of the storm sewers. In streets, inlets shall normally
be located along the curb line and at or beyond the curb radius points.
For the purpose of inlet location at corners, the depth of flow shall
be considered for each gutter. At intersections, flow across through
streets shall be avoided but, if unavoidable, will not exceed one
inch in depth. Pennsylvania Department of Transportation standard
two-foot by four-foot Type C, M, S inlets or approved equivalents
should be used. Inlets shall be depressed two inches below the grade
of the gutter or ground surface. Manholes may be substituted for inlets
at locations where inlets are not required to handle surface runoff.
(3)
Storm sewers shall have a minimum diameter of 15 inches and
shall be coated, corrugated metal pipe with paved inverts, reinforced
concrete pipe, or HDPE (high density polyethylene) pipe. Concrete
pipe shall be used within the street right-of-way and in other areas
required by the Township Engineer. Minimum pipe slope shall be 1/2%.

K. After expiration of the eighteen-month maintenance period, all shade trees shall be regulated by the Salisbury Township Tree Maintenance, Removal, and Replacement Ordinance (Chapter
25).
[Ord. 6-97-429, 6/12/1997;
as amended by Ord. No. 07-2021-637, 6/24/2021]
1. Salisbury Township adopts the Comprehensive Plan of Salisbury Township,
Community Facilities Plan, Recreation and Open Space, adopted May
28, 1992, by the Board of Commissioners as the Recreation Plan for
Salisbury Township.
A. Purpose. To provide adequate open spaces, recreation lands and recreation
facilities to serve new residents of new developments, for both active
and passive recreation, and to recognize and work to carry out the
Recreation Plan for Salisbury Township. This section shall apply to
any major subdivision, minor subdivision or residential land development
reviewed and approved by the Township, but shall not apply to any
resubdivision or lot consolidation plan.
B. Limitations on Use of Fees.
(1)
Any fees collected under this section shall be accounted for
separately from other Township funds.
(2)
To ensure that the lands and facilities are accessible to the
residents and employees of the developments that paid fees towards
their cost, the Township designates two recreation fee districts.
These districts are the Eastern Recreation Fee District and the Western
Recreation Fee District. Any fees collected under this section shall
only be expended within the same recreation fee district as the subdivision
or land development that contributed the fees.
(3)
Such fees shall only be used for the following: acquisition
of public open space, development and/or redevelopment of existing
or proposed public recreational facilities, landscaping of public
open space and closely related engineering and design work.
C. Land Dedication. Any subdivision or multifamily land development
regulated under this section shall be required to dedicate the specified
amount of common open space, unless the Township determines that such
land in that location would not be desirable or efficient based upon
the standards of this section, in which case recreation fees-in-lieu
of land shall be required.
(1)
Generally, it is the intent of this section that development
of 10 or fewer dwelling units that do not include land that is adjacent
to existing publicly-owned land should be required to pay recreation
fees in lieu of dedicating land.
(2)
The land and fee requirements of this section shall be based
upon the number of new dwelling units that would be permitted on the
lots of a subdivision or land development after the plan is approved.
(3)
Prime Open Space. For the purposes of this section, the term
"prime open space" shall mean land proposed to be dedicated as common
open space that would meet all of the following standards:
(b)
Not a wetland under federal and/or state regulations.
(c)
Be part of a contiguous tract of at least two acres (which may
include preexisting common open space that is adjacent).
(d)
Not be within the 100-year floodplain, as defined by official
floodplain maps of the Township.
(4)
Amount of Common Open Space. A subdivision or land development
shall be required to dedicate the following amounts of common open
space for each permitted new dwelling unit, unless the Board of Commissioners
determines that recreation fees in lieu of the open space would be
more in the public interest:
Percentage of the Total Required Common Open Space that Would
Meet the Definition of Prime Open Space
|
Minimum Required Common Open Space Per Permitted Dwelling Unit
|
---|
0% to 25.0%
|
2,000 square feet
|
25.1% to 75.0%
|
1,500 square feet
|
75.1% to 100%
|
1,200 square feet
|
D. Fees for Residential Development. If the Board of Commissioners determines
that a land dedication within a proposed subdivision or land development
would not be in the public interest, the applicant shall be required
to pay fees in lieu of dedicating open space. A notation stating that
such fees are required shall be stated on the final record plan. This
fee shall be established, per permitted dwelling unit, and is included
in the Township Fee Schedule, which may be updated from time to time
by resolution of the Board of Commissioners.
E. Decision on Land vs. Fees. The Township shall determine whether a
land dedication or the payment of fees shall, or a combination of
the two shall be required. This determination should, but is not required
to, be made at the time of sketch plan review. The Township should,
at a minimum, consider the following in reaching its decision:
(1)
Whether the land in that location would serve a valid public
purpose and be suitable for active or passive recreation.
(2)
Whether there is potential to make a desirable addition to an
existing public recreation area.
(3)
Whether the proposed land would meet the objectives and requirements
of this section and any relevant policies of the Township Comprehensive
Plan.
(4)
Whether the area surrounding the proposed development has sufficient
existing recreation and open space land, and whether it is possible
for pedestrians and bicyclists to reach those lands.
(5)
Any recommendations that may be received from the Planning Commission,
Township Engineer, the Recreation Advisory Committee and other Township
staff.
(6)
Whether the proposed open spaces would preserve important natural
features (such as woodlands or creek valleys) that might otherwise
be negatively affected.
(7)
Whether it could be possible to combine common open space on
this tract with the additional open spaces on an adjacent tract, when
the tract is developed in the future.
F. Common Open Space to Be Dedicated.
(1)
Land required to be dedicated shall be suitable for its intended
purpose. The applicant shall state what improvements, if any, he/she
intends to make to the land to make it suitable for its intended purpose,
such as rough grading, landscaping or development of trails. Such
land shall be free of construction and other debris at the time of
dedication.
(2)
Required common open space shall be dedicated to the Township,
unless the Board of Commissioners agree to allow a dedication to any
of the following: the Salisbury Township School District, the County,
a homeowner association or an environmental organization acceptable
to the Board of Commissioners. In the case of a rental development,
the Township may permit the common open space to be retained by the
owner of the rental development.
(3)
If required common open space is to be owned by a homeowner
association, the developer shall establish such association in a form
that requires all property owners within the development to annually
contribute to the maintenance of the common open space. Provisions
of any homeowner association agreements regarding required common
open space shall be subject to acceptance by the Board of Commissioners,
based upon review by the Township Solicitor. The provisions of § 705(f)
of the MPC should serve as a model for such agreement.
(4)
Any required common open space dedication shall include deed
restrictions to permanently prevent the development of buildings,
except buildings for noncommercial recreation or to support maintenance
of the land for recreation.
(5)
Priority shall be given to dedication of land in approximate
locations identified by the Township Comprehensive Plan.
(6)
Areas intended for active recreation shall be well-drained,
of less than 4% average slope and not require filling in of a wetland
for use.
(7)
Land shall not be used to meet the minimum requirements for
common open space if it has any of the following conditions:
(a)
Lacks adequate access for maintenance and for pedestrians.
(b)
Is not suitable for either active or passive recreation.
(c)
Is within a stormwater detention basin, unless the applicant
proves to the satisfaction of the Board of Commissioners that such
area would be designed so that it clearly would be usable on a regular
basis for recreation.
(d)
Is required to be provided under another section of this chapter
or another Township Ordinance.
(e)
Is within 15 feet of any principal building.
(f)
Is within 15 feet of a parking area of more than six parking
spaces (other than parking areas specifically developed to serve the
open space).
(g)
Would result in a total contiguous tract of common open space
of less than one acre.
(h)
Is within the right of way or easement of an overhead electric
power line with a capacity of 35 KV or higher.
(8)
Residual Lands. If only a portion of a larger tract is currently
proposed to be subdivided, or the applicant owns one or more adjacent
tracts that are not currently proposed to be subdivided, the applicant
shall provide a sketch of a possible future land dedication on these
adjacent lands in case they would be developed in the future.
(9)
Coordination With Future Adjacent Dedication. The Board of Commissioners
may require that a required land dedication within a property currently
being subdivided be placed along an edge of the property so that it
may, in the future, be combined with an open space dedication on the
edge of an adjoining property when that adjoining property is subdivided
or developed.
G. Combination of Land and Fees. Upon approval, the Township may accept
a combination of common open space and fees in lieu of land to meet
the requirements of this section for a residential subdivision or
land development. This combination shall be based upon the common
open space requirement that applies to a certain number of dwelling
units and the fee in lieu of land requirement that applies to the
remaining number of dwelling units.
H. Timing of Fees. Fees required under this section shall be paid prior
to the recording of the final plan, except as follows:
(1)
If the Township agrees to provisions in a binding development
improvement agreement to require the payment of all applicable recreation
fees prior to the issuance of any building permits within each clearly
defined phase of the development, then the fees are not required to
be paid prior to recording of the final plan but may instead be paid
within the requirements of that development agreement.
(2)
If the applicant agrees to pay such fees in installments, then
all such fees shall not be considered to be paid, for the purposes
of any applicable time limitations for utilization under the MPC,
until all such fees are paid in full, including all installments and
phases.
I. Facilities in Place of Land or Fees. An applicant may seek a modification from the recreation fee or open space requirements of this section under the procedures of §
22-1202 of this chapter by substituting for such fee the construction of permanent recreation facilities within the proposed subdivision or land development, on nearby public open space, and/or within existing nearby parks or Recreation areas. The applicant must demonstrate to the satisfaction of the Board of Commissioners that the value of the proposed permanent recreation facilities will be approximately equal or greater than the land or fees that would otherwise be required. Permanent recreation facilities may include any play equipment, courts, ballfields, picnic areas, pavilions, bike paths, parking areas or other facilities related or accessory to public recreation. The cost of improvements for any recreation facilities proposed under this section will be determined by the Township.
[Ord. 6-97-429, 6/12/1997;
as amended by Ord. No. 07-2021-637, 6/24/2021]
1. Purposes. To allow the Township to determine the safety and congestion
impacts, and related costs, of proposed major traffic generating uses.
To require that applicants respond with reasonable proposals to resolve
the negative traffic impacts that their proposed uses will cause on
the public. To recognize that sufficient federal, state, and Township
funds are not available to resolve traffic problems caused by private
development. To assist in carrying out §§ 502(2)(ii)
and 503(3) of the Pennsylvania Municipalities Planning Code, as amended.
To ensure that streets bordering a subdivision or land development
are coordinated and of such widths and grades and in such locations
as deemed necessary to accommodate prospective traffic and to facilitate
fire protection. To ensure that the access into and out of subdivisions
and land developments is reasonably safe.
2. Administration.
A. The full cost of the traffic study shall be borne by the developer.
B. The traffic study shall be reviewed by the Township Engineer or alternate
Township Engineer, the cost of which shall be borne by the developer.
C. The project manager for any traffic impact report shall be a registered
professional traffic engineer.
D. The Township shall require such on-site traffic improvements to be
provided by the applicant, as deemed appropriate, in light of the
traffic impact study as a specific condition of preliminary plan approval
for all land developments, subdivisions, or conditional use applications
for which a study has been required.
E. Joint traffic studies between different developers are acceptable.
3. Contents of a Traffic Study.
A. Project information containing the following data:
(1)
Developer and project name.
(3)
Identification of an appropriate transportation study area for
the proposal. (Prior to the start of a traffic study, the applicant's
traffic engineer shall meet with the Township Engineer or alternate
Township Engineer to establish the limits of the study area and the
streets and intersections to be studied).
(4)
Identification of existing and proposed site use(s) and intensity
of development (e.g., number and type of dwelling units, square footages,
etc.).
(5)
Identification of current and proposed land uses within the
identified study area.
(6)
Any staging of development and completion date.
B. Traffic Facilities Description, Existing traffic conditions shall be measured and documented for all streets and intersections in the identified study area. [See §
22-1018, Subsection
3A(3)]. Existing traffic volumes for average daily traffic, peak highway hour(s) traffic and peak development-generated hour(s) traffic shall be recorded. Traffic counts at designated intersections in the study area shall be conducted, encompassing the peak highway and peak development generated hour(s), and documentation shall be included in the report. A volume/capacity analysis based upon existing volumes shall be performed during the peak highway hour(s) for all designated streets and intersections in the study area. Levels of service shall be determined for each roadway segment to be studied and including all turning movements. Detailed traffic counts of existing local streets are not required, unless recommended by the Township Engineer. A tabulation of specific accident data including locations and types of accidents for the most recent four-year period shall be included in the analysis. This analysis will determine the adequacy of the existing roadway system to serve the current traffic demand. Roadways and/or turning movements experiencing levels of Service D, E, or F, as described in TRB Special Report 209: Highway Capacity Manual, Third Edition (1994), shall be noted as congestion locations.
C. An analysis of future traffic conditions without proposed development.
The total future traffic demand shall be calculated and analyzed.
This demand shall consist of a combination of the existing traffic
expanded to the proposed project build-out year and the traffic generated
by other anticipated development within the study area. This analysis
shall be performed for the peak hour(s) for all roadways and designated
intersections in the study area. Level of service (LOS) calculations
shall be provided for all designated intersections within the study
area. All access points shall be examined as to the necessity of installing
traffic signals. This evaluation shall compare the projected traffic
to PennDOT warrant regulations for traffic signal installation.
D. Traffic Impact of the Development. Estimation of vehicular trips
resulting from the proposed project shall be completed for the peak
highway and peak development-generated hour(s). Vehicular trip generation
rates to be used for this calculation shall be obtained from the most
recent Trip Generation Manual, published by the Institute of Transportation
Engineers. These development generated traffic volumes shall be provided
for the inbound and outbound traffic movements as estimated, and the
reference source(s) and methodology followed shall be documented.
All turning movements shall be calculated. These generated volumes
shall be distributed to the area and assigned to the existing streets
and intersections throughout the study area. Documentation of all
assumptions used in the distribution shall be provided. Traffic volumes
shall be assigned to individual access points. Any characteristics
of the site that will cause particular trip generation problems shall
be noted. The impact of any diversion or rerouting of existing traffic
by the proposal shall be analyzed. For retail sales uses, the increased
traffic during the Christmas season and during weekends shall be forecast
and analyzed.
E. An analysis of future traffic conditions with proposed development.
The total future traffic demand shall be calculated and analyzed.
This demand shall consist of a combination of the existing traffic
expanded to the proposed project build-out year, the proposed development-generated
traffic, and the traffic generated by other proposed development within
the study area. This analysis shall be performed for the peak hour(s)
for all designated roadways and intersections within the study area.
All access points shall be examined as to the necessity of installing
traffic signals. This evaluation shall compare the projected traffic
to PennDOT warrant regulations for traffic signal installation.
F. Recommendations and Conclusions. Levels of service for all designated
streets and intersections within the study area shall be listed. All
streets and/or intersections showing a level of service below "C"
shall be considered deficient and specific recommendations for the
elimination of these problems shall be identified. This listing of
recommended improvements shall include, but not be limited to, the
following elements: internal circulation design, site access location
and design, external roadway and intersection design and improvements,
and traffic signal installation and operation including signal timing.
All physical street improvements and existing traffic control devices
shall be shown on plan drawings.
G. An estimate of the costs of the required improvements. Approximate
costs for all required improvements within the study area shall be
developed.
H. A statement about the financial responsibilities for the needed improvements.
The applicant shall respond to the traffic impact report by stating
what on-site improvements he/she proposes and to what degree he/she
is willing to assist in funding any off-site improvements that are
identified in the traffic study. The improvements financing must be
consistent with the Pennsylvania Municipalities Planning Code, as
amended, Article V-A, Municipal Capital Improvement.
I. An improvement construction schedule. Such schedule shall include
priority listing of the needed improvements. The expected beginning
and ending of construction for each improvement shall be identified.
4. Timing of Required Traffic Improvements. For developments not the
subject of an improvements agreement under this chapter, no occupancy
permit shall be granted for a use or uses until such traffic improvements
that have been required by PennDOT and the Township to serve the use
are in place and operating, unless the Board of Commissioners require
or allow funds for a required traffic improvement to be placed in
a dedicated escrow account to be used when such improvements are warranted.
[Ord. 6-97-429, 6/12/1997;
as amended by Ord. No. 07-2021-637, 6/24/2021]
1. If the Township has reason to believe that a portion of a site proposed
to be altered may meet the state or federal definition of a wetland,
the Township may require the applicant to provide an on-site study
by a qualified professional delineating the locations of wetlands.
However, the Township accepts no responsibility to identify all wetlands
or to warn parties of such possibilities. The presence of hydric soils,
hydric vegetation typically found in wetlands or other hydrological
indicators may be indicators of an area needing more-detailed study.
Sufficient information shall be provided to the Township for a thorough
review.
2. Erosion. All Township permits are granted on the condition that state
erosion and sedimentation regulations and any officially submitted
erosion and sedimentation plan are in compliance. Failure to comply
with such regulations or plan shall be cause for suspension of Township
permits.
3. Steep Slopes. If slopes of greater than 15% are to be disturbed,
the applicant shall submit to the Township and carry out an acceptable
sedimentation and erosion control plan, regardless of the project
size. The Township may require that such plan be submitted to and
found acceptable by the Lehigh County Conservation District. The plans
shall be in compliance with all state sedimentation and erosion control
regulations that are in effect at the time of the approval of the
erosion and sedimentation control plan, and compliance with such regulations
shall be a condition of all permits issued under this chapter. Exceptions
to this requirement are:
A. Accessory Structures. The construction or placement of a customary
accessory structure or use of up to 600 square feet of building coverage
on a lot after the issuance of the original occupancy permit for a
principal building or structure, provided that no earthmoving shall
occur on areas of over 25% slope.
B. Man-Made Slopes. The alteration of slopes that were clearly lawfully
man-made (such as walls of a detention basin or quarry or excavated
banks along a street) shall be regulated by a reasonable estimate
of the natural slope of such land and not by the degree of such man-made
slope.
C. Recreation. The development of noncommercial open space recreation
uses by a governmental agency or an established nature conservation
organization, including, but not limited to, parking to serve common
open space or the development of public recreational facilities.
4. Earthmoving on Slopes. No earthmoving activities shall occur within
a construction area or in preparation for or related to construction
or development, on slopes of over 25% in any zoning district, except
if the applicant proves to the satisfaction of the Township that all
of the following conditions would be met:
A. That disturbance of such slopes is necessary to allow development
of a single permitted principal use or single principal building on
an undeveloped existing lot of record of at least six acres. This
shall not permit disturbance of slopes of greater than 25% for expansion
of an existing use or building.
B. That slopes of over 30% will not be altered or disturbed.
C. That there are no areas of less than 25% slope on the lot that are
reasonably physically suitable for the construction area.
5. Increase of Slope.
A. If more than 5,000 square feet of land area is increased in slope
so that the average resulting slope is greater than 15% and more than
6% above the preexisting slope, the applicant must prove to the satisfaction
of the Township Engineer that stormwater will be adequately managed
to prevent increased flooding or erosion to other properties.
B. The maximum slope resulting from excavation or earth fill shall be
three feet horizontal to one-foot vertical, unless the applicant provides
professional engineering certification acceptable to the Township
Engineer that the finished slopes will be safe and stable.
6. Drainage. The ground adjacent to a building shall be graded so that
surface water will be drained away from such building.
7. No grading shall be completed in such a way that soil, rocks, or
other debris is left in an unsightly fashion nor in a fashion that
interferes with drainage, streets, or utilities.
8. Fill. Materials used for fill as a future base for construction shall
be nonbiodegradable, well-compacted and provide a suitable and secure
base. The Township may require that an applicant fund appropriate
underground testing of a proposed building site if there is reasonable
doubt, in the opinion of the Township Engineer, that the subsurface
is suitable and secure for a proposed use.
9. Vegetation. Within a setback required under Subsection
3, the applicant shall describe natural vegetation and trees that will be removed or replaced. Where trees and natural vegetation are removed within such setback, the applicant shall plant new trees and other vegetation that will serve the same or better environmental effect to avoid erosion and to filter pollutants from runoff.
10. High-Water Table Soils.
A. At the time of review of a proposed subdivision or land development,
the Township may require that an on-site investigation be conducted
for the purpose of determining the location of a high-water table
if any of the following conditions exist:
(1)
Soil mapping of the United States Natural Resources Conservation
Service or a more-reliable source indicates that the area includes
soils with a seasonal depth to water table of less than three feet
below the surface;
(2)
Wetlands are present on the property; or
(3)
There are other visual indicators of the presence of a high-water
table.
B. The Township may require that test excavations be subject to observation
by a representative from the Township. The determination of areas
with high water table shall be made by a qualified soil scientist
or other professional who is acceptable to the Township.
C. Areas that are to be permanently restricted against use for any buildings
or parking through an easement or deed restriction are not required
to be tested.
D. The lowest enclosed floor of a new principal building, including
any basement, shall be built a minimum of 24 inches above the seasonal
high-water table elevation. Any new principal building shall be constructed
to limit the need for groundwater pumping.
