[Ord. 3/29/1990B, § 800; as amended by Ord. No.
22-05, 5/5/2022]
1. The standards and requirements outlined herein shall be considered
minimum standards and requirements for the protection of the health,
safety, and general welfare of the residents of New Hanover Township.
In addition, the Board of Supervisors reserves the right to require
standards in excess of the minimum requirements if warranted to protect
the health, safety, and general welfare of the community.
2. The following principles, standards and requirements shall be applied in evaluating plans for a proposed subdivision or land development. The standards of Chapter
27, Zoning, for the particular district in which the subdivision or land development is taking place shall govern the layout of lots and/or design of buildings, parking lots and other facilities.
[Ord. 3/29/1990B, § 801; as amended by Ord. 97-7, 10/13/1997, § 802; and by Ord. No. 22-05, 5/5/2022]
1. All portions of a tract being subdivided or developed shall be taken
up in lots, streets, public lands or other proposed uses, so that
remnants and landlocked areas shall not be created.
2. In general, lot lines shall follow Township boundary lines rather
than cross them.
3. Subdivisions and land developments shall be properly designed in order to prevent the necessity for excessive cut or fill. Subdivisions and land developments shall be laid out to come as close as possible to balancing cut and fill operations on site. A grading plan for the entire site shall be submitted in conformance with §§
22-305 and
22-307. Plans shall be designed to avoid excessive disturbance of vegetation and movement of earth.
4. No land shall be developed or plotted for residential purposes unless
all hazards to life, health or property including, but not limited
to, flood, fire and disease have been eliminated or unless the plans
provide adequate safeguard against such hazards without disturbing
the natural condition of the land.
5. On lots less than two acres, land subject to flooding, streams, wetlands,
and wetland margins shall not be plotted for residential occupancy
and shall be excluded from the calculation of minimum lot area. Development
and disturbance of floodplain land areas shall be governed by additional
standards contained in this Part 8, the New Hanover Township Zoning
Ordinance, and the New Hanover Township Building Code.
6. Where trees, groves, waterways, scenic areas, historic sites or other
community assets and landmarks are located within a proposed subdivision
or land development, every possible means to the fullest extent shall
be provided to preserve these features.
7. Unless a permit is obtained from Pennsylvania Department of Environmental
Protection (PaDEP), discarded building material shall be disposed
of in a manner consistent with the applicable laws of the commonwealth.
Such material shall not be disposed of onsite but shall be taken to
a licensed disposal facility.
8. The proposed subdivision or land development shall be coordinated
with the existing adjacent neighborhoods so that the community as
a whole may be developed harmoniously.
9. The applicant shall construct, install, and guarantee, at no expense
to the Township or its authorities, all improvements required as part
of plan approval, including, but not limited to, streets, curbs, sidewalks,
trails, water and sewage facilities, stormwater management facilities,
street lights, fire hydrants, road signs, monuments, lot pins, utilities,
and shade trees.
[Added by Ord. No. 22-05, 5/5/2022]
1. Comprehensive Plans. Proposals for land development or subdivision
shall be generally consistent with Pottstown Metropolitan Regional
Comprehensive Plan and New Hanover Township Comprehensive Plan 2040,
especially as to the use of land, intensity of development, transportation,
community facilities, and resource protection. Residential development
should also be consistent with the housing element of the plan. All
proposals should be located in areas designated for development in
the future land use plan element and be serviced by currently available
infrastructure or infrastructure that will be developed concurrent
with the development.
2. Other Plans. Proposals shall be generally consistent with the appropriate
state, regional, county, and the municipally adopted comprehensive
plan and other plans. Where regional facilities are proposed in the
plan, such as highways, effort shall be made to preserve needed right-of-way
for future infrastructure projects in the proposed land development
or subdivision.
3. Public Service Improvements. Proposals shall be consistent with the
location and timing of public service improvements, such as water
and sewage facilities, in accordance with the appropriate infrastructure
plans governing those facilities. In addition, the location of public
service facilities as outlined in a capital improvement program or
official map should be considered.
[Added by Ord. No. 22-05, 5/5/2022]
Proposed land developments and subdivisions should be designed
to address the opportunities and limitations present on a site and
its adjacent surroundings. The plan should use site opportunities
to enhance the overall quality of the development and lessen potential
negative impacts upon the site and the surrounding community. The
physical, social, and psychological needs of the users of the site
should be evaluated and appropriately incorporated into the final
subdivision layout or site design. The impacts of the proposed development
on the natural environment and surrounding land uses should be given
a high priority and made an integral part of the overall design for
the land development and subdivision. The following principles of
site organization should be considered:
1. Site Improvement Layout. The buildings should be placed in consideration
with the site's topography, existing vegetation, and surrounding land
uses, taking into account energy conservation, solar access, and pertinent
natural features.
2. Existing Natural Features. Existing natural features should be recognized
and integrated into the site layout. Natural features such as streams,
hillsides, wetlands, unique habitat, woodlands, and similar natural
resources should be considered strong design determinants and be incorporated
into the overall site plan to strengthen the unique quality of the
land.
3. Open Space and Scenic Views. The placement of open space and preservation
of scenic views should be a fundamental design decision. Open space
lands should provide for a variety of benefits including recreation,
agriculture, natural resource protection, scenic views and vistas,
and buffers for site elements and land uses.
4. Circulation. Movement within a site and access to the site should
be designed for the safety and convenience of various types of users.
Cross access between properties and joint access are encouraged to
improve circulation and improve access safety.
5. Relationship to Surrounding Uses. The proposed design should complement
appropriate surrounding uses through building setbacks, buffers, and
separation of uses. Various potential negative impacts upon surrounding
land uses including noise, light, and loss of privacy should be mitigated.
6. Health Hazards. The configuration of a subdivision or land development
should reduce risk or hazards to health, safety and wellbeing of future
users of the subdivision or land development and to the community
as a whole.
7. Concept Development Plan. Where an applicant seeks approval for the
development of a portion of a tract with the intent that the remainder
would be developed at a future date, the applicant shall submit with
the initial application a concept development plan showing with specificity
the portion of the tract intended for current development and showing
in concept form the manner in which the balance of the tract might
be fully developed in conformance with Township regulations.
A. The intent of such a submittal is to enable the Township to review
the basic site design concept, to advise the applicant and to assure
that the current development of the property properly anticipates
the future development.
B. The concept development plan must present a comprehensive overview
of potential uses to which the property demonstrates conformance with
the current Township codes.
[Ord. 3/29/1990B, § 802; as amended by Ord. 93-3, 2/8/1993, § 29; by Ord. 17-03, 3/27/2017; and by Ord. No. 22-05, 5/5/2022]
1. Lot Size and Width.
A. Each lot shall comply with the minimum area and width requirements
of the Zoning Ordinance and be generally sufficient in size and shape to adequately
accommodate the development or use proposed for it. Lots two acres
or larger that contain natural restrictions such as lands subject
to flooding, streams, wetlands, wetland margins, or other natural
features shall be made large enough to provide suitable area for the
intended use of the lot without requiring encroachment upon natural
amenities. Lots smaller than two acres with land subject to flooding,
streams, wetlands, and wetland margins shall not be plotted for residential
occupancy and shall be excluded from the calculation of minimum lot
area, per § 22-802.5.
B. Lots with existing or planned public improvements such as fuel pipelines,
underground utility easements, stormwater detention basins, high-voltage
power lines, or other facilities should be sized to allow suitable
room for the intended use of the lot without requiring encroachment
on the public facilities or easements.
C. Lot areas, exclusive of described and measurable easements, shall not be less than specified by the provisions of Chapter
27, Zoning.
2. Lots shall be designed and sized to meet the natural resource protection standards or §§
22-831 and
22-832 of this chapter and §§
27-2101 and
27-2102 of Chapter
27, Zoning.
3. Lot Frontage. Every lot shall have a minimum of 30 feet of frontage
along the right-of-way of a public, private, or common street. Sufficient
frontage is the minimum width required to site a driveway into the
property in accordance with the design requirements in this section,
the New Hanover Township Zoning Ordinance, and other appropriate state,
federal, and local regulations. Corner lots will meet lot frontage
requirements on two streets. Where feasible, lot lines shall follow
municipal boundaries rather than cross them.
4. Through lots shall be deed restricted to limit access to the lower
order street.
5. Lot Lines. Lot lines shall be drawn parallel, concentric, at right
angles, or radial to the street right-of-way line unless not feasible
or undesirable due to existing, permanent, natural or man-made features
or need for energy efficiency. Where possible, lot lines shall coincide
with abutting lot lines. Lot lines shall not cross streets. Generally,
lot corners of several lots should coincide.
6. Lot Shape. Deep, narrow lots and wide, shallow lots are to be avoided.
The depth of a lot shall not exceed 2.5 times its width at the building
line. The depth and width of parcels intended for nonresidential uses
shall be adequate for the use proposed and sufficient to provide satisfactory
off-street parking, access, loading and unloading, setbacks, landscaping,
buffers, etc.
7. Where feasible, lot orientation shall provide for proper solar access.
This is achieved by building placement with the long axis in a general
east-west direction.
8. Reverse Frontage Lots. Reverse frontage lots may be used as an alternative to marginal access streets or normal lotting when the lots abut a collector street or street of a higher classification or has natural conditions along one street that prevents safe access. When reverse frontage lots are used, an additional 25 feet shall be added to the minimum rear yard setback abutting a collector street or street of a higher classification, to provide a landscaped buffer area in the rear yard in accordance with §
22-835.
9. Rear or Flag Lots.
A. Purpose of Rear or Flag Lots.
(1)
To permit reasonable subdivision of land which is physically
constrained by an unusual configuration of the tract or limited road
frontage, and which could not be subdivided in a desirable manner
using conventional streets and lot geometry.
(2)
To preserve farmland, woodland, scenic views, historic sites,
or other environmental amenities by locating buildings away from roads.
(3)
To avoid access to a collector street or a street of a higher
classification.
(4)
To avoid building an unnecessary road.
B. Parts of a Rear or Flag Lot. Rear or flag lots shall be comprised
of two parts, the access strip and the body of the lot, in compliance
with the following standards:
(1)
The access strip shall be a minimum of 30 feet wide for its entire length unless the body of the flag lot is likely to undergo further subdivision in the future. If a flag lot is capable of subdivision in the future and is not deed restricted against further subdivision, the access strip must be at least 50 feet wide and be able to contain a road capable of meeting all appropriate public street and intersection standards contained in this Part
8. When an access strip is designed for a future road, a note shall be placed on the plan reserving the access strip for a future road; however, dedication is not required.
(2)
The access strip shall be a fee-simple part of the rear or flag
lot and shall not be a separate parcel or easement. This portion of
the lot shall not be used for any purpose other than the location
of an access driveway. Vehicle parking, sewage disposal systems, and
the development of any structures shall be specifically prohibited
in the access strip.
(3)
The body of a flag lot shall comply with all of the minimum
dimensional requirements of the zoning district in which it is located.
The area of the access strip shall not be counted toward the minimum
lot area requirement.
(4)
The front yard of the rear or flag lot shall be parallel to
the frontage street. In the event the access strip is proposed for
a future road, a second front yard for the purpose of establishing
setbacks shall be measured from the potential access road.
(5)
All minimum setback requirements in the applicable zoning ordinance
shall be increased by 25% in flag lots.
C. Review Factors. Flag lots shall only be allowed when the Board of
Supervisors, based upon advice from the Township Planning Commission
and Township Engineer, has determined the following:
(1)
Flag lots would enhance the rural character of their proposed
location.
(2)
The minimum number of flag lots needed are being proposed. Further
subdivision of flag lots shall not be permitted.
(3)
The access would allow for the minimum safe sight distance criteria
to be met for the driveway and/or local road requirements, depending
on the total number of lots.
(4)
The use of flag lots will result in saving trees, avoiding steep
slopes, and preserving floodplain, wetlands, agricultural lands, and
other environmental features, if present.
(5)
Flag lots would provide a positive fiscal economic impact on
the municipality by limiting future road maintenance.
D. Design Standards for Flag Lots.
(1)
Any access strip that is shared by three or more lots shall be designed to meet the Township's new residential street requirements. All other access strips shall be designed to meet the Township's driveway standards. Compliance with the Township driveway and/or new residential street standards in §
22-819 and
22-816, respectively, are to be followed.
(2)
The length of the access strip shall be kept to a minimum. As
a guide, the preferred length is approximately equal to the depth
of one lot which complies with the minimum lot width and area requirements
of the district in which it is located. No access strip shall exceed
two times the lot depth described above, unless the primary purposes
of the additional length are to preserve farmland or other land for
preservation of agriculture or rural character, by locating new development
remote from road frontage.
(3)
The location of the access strip should be logical relative
to the body of the rear lot, surrounding lot configurations, and natural
features of the land, and it shall intersect the public street at
a safe, visible location.
(4)
Turns greater than 120° or with a radius less than 150 feet
and vertical grades in excess of 10% are prohibited in access strips.
It may be necessary to widen the access strip at such sharp turns
and steep slopes to accommodate grading, drainage, tree preservation,
or emergency vehicles. Access strips that may become future roads
shall be configured to accommodate horizontal curves required for
roads. Emergency vehicle turning templates shall be provided to verify
that emergency access can be provided. As part of this, a vertical
profile for the entire driveway length shall be provided to ensure
that the emergency vehicle or other vehicles utilizing the driveway/access
will not have issues.
(5)
Driveways with access strips shall be paved from the edge of road pavement to a distance commiserate with the required stopping space per §
22-819.
(6)
Joint driveways are permitted among both front and rear lots.
No more than two access strips may abut each other. Each pair of access
strips must share a common access point and driveway from the edge
of pavement to a distance of at least 50 feet beyond the ultimate
right-of-way line of the road, from which point either one common
driveway or two individual driveways may continue. The shared portion
shall be a minimum of 16 feet wide. Shared portions of driveways may
be wider where access is taken from collector streets or streets of
a higher classification.
(7)
Access points to flag lots, whether single or paired, shall
be separated by at least 100 feet as measured along the right-of-way
from all other existing and/or proposed driveways when providing access
to two or less lots and the minimum intersection spacing when serving
three or more lots. Separation distance shall be measured from the
center point of the nearest access strips unless specific driveway
access points have been clearly established.
(8)
No more than one "tier" of flag lots shall be permitted on a
tract. In other words, a flag lot may not be located behind another
flag lot.
(9)
In a subdivision of five or more lots, flag lots may comprise
no more than 15% of the total number of lots, rounded to the nearest
whole number.
(10)
Flag lots are not permitted to gain access from an existing
or proposed single-access street.
(11)
The access strip must serve as the primary access point for
the lot unless a common drive or access is gained through an easement
at a safer and less environmentally damaging location.
[Added by Ord. No. 22-05, 5/5/2022]
1. The ideal block length measured along the building frontages is 1,000
feet. The minimum block length shall be 400 feet and the maximum block
length shall be 1,600 feet unless the zoning ordinance specifies different
minimum and/or maximum lengths.
2. When reverse lots are used, the block width shall be in accordance
with the reverse frontage lot standards in § 22-805.8.
3. Blocks should be designed to continue New Hanover Township's existing
street pattern and provide efficient, convenient, and safe pedestrian
and vehicular circulation.
4. Blocks should be designed to reflect natural features that may constrain
subdivision and land development. Unless a watercourse is located
along the rear of lots in the block, drainage should be away from
the interior of the block toward the abutting streets.
5. Where blocks are longer than 1,000 feet, pedestrian crosswalks may
be required in locations deemed necessary by the Board of Supervisors
and/or Township Traffic Engineer. These mid-block crosswalks shall
then be designed in accordance with PennDOT's Publication 46 requirements,
as amended, as well as the Township's requirements for ADA curb ramps.
[Ord. 3/29/1990B, § 803; as amended by Ord. 97-7, 10/13/1997, § 804; and by Ord. No. 22-05, 5/5/2022]
1. Widths and locations of easements and rights-of-way shall be determined
by the Township Engineer or the appropriate authority or utility company
for all utilities, including stormwater facilities. The location and
design of the utilities shall be governed by the requirements herein.
A. General Standards.
(1)
Easements and required front, side or rear yards may co-occupy
the same land as utilities.
(2)
Nothing shall be permitted to be placed, planted, set or put
within the areas of an easement unless it is a portable or removable
object. The area shall be kept as lawn.
(3)
The owner of any lot, upon written request by the Township and
at the owner's sole expense, shall remove anything placed, planted,
set or put within an area of any easement.
(4)
To the fullest extent possible, easements shall be adjacent
to rear or side lot lines and occupying only a portion of one lot,
rather than being centered on two lots.
B. All easements and rights-of-way, including descriptions of any restrictions
thereof, shall be shown on the record plan and shall be recited in
a deed for each and every property describing the subject area. Any
error found in a deed shall be immediately corrected and re-recorded
in the office of the Recorder of Deeds for Montgomery County at Norristown,
Pennsylvania, at the sole expense of the applicant.
C. Utility Easements. A minimum width of 20 feet shall be provided for
common utilities and drainage when provided in undedicated land for
one use. Multiple utility uses within one easement require additional
easement width.
D. Public Utilities. All water, sewer, and gas mains and other underground
facilities shall be installed prior to street paving at locations
approved by the Township Engineer.
E. Underground Utilities. All water, sewer, and gas mains shall be installed
underground. All electric, telephone and communication services, both
main and service lines, shall be provided by underground cables, installed
in accordance with the prevailing standards and practices of the utility
or other companies providing such services, except where it is demonstrated
to the satisfaction of the Board of Supervisors that underground installations
herein required are not feasible because of physical conditions of
the lands involved. All main underground cables which are within the
right-of-way of a street shall be located as specified by the utility
company, subject to approval by the Board of Supervisors, upon recommendation
of the Township Engineer.
(1)
In order to promote and facilitate the underground installation
of utility distribution lines, a letter of endorsement shall be required
from the suppliers of utility service (not limited to electrical,
telephone, or cable television) of the developer's choice wherein
the applicant acknowledges that underground utilities are feasible
and shall be consummated as part of the improvement plan.
(2)
A statement relative to the intent of the developer to provide
underground utility service shall be placed on the final plan requisite
to final approval of the plan.
(3)
The provisions in this chapter shall not be construed as to
limit or interfere with the construction, installation, operation,
and maintenance of public utility structures or facilities which may
hereafter be located within public easements or rights-of-way designated
for such purposes.
(4)
Light standards are to be placed as required by Ordinance. Power
source for such standards shall be placed underground, as required.
(5)
Along arterial and collector roads, all new electrical service
shall be placed underground.
F. Access easements shall be provided where there are common driveways
or shared access arrangements.
G. Where a subdivision or land development is traversed by a watercourse,
there shall be provided a drainage easement or right-of-way conforming
substantially with the line of such watercourse and of such width
as will be adequate to preserve natural drainage but not less than
20 feet, or as may be required or directed by the Township and/or
the Department of Environmental Protection. The owner shall properly
grade and stabilize slopes and fence any open ditches when it is deemed
necessary by the Township.
H. Where swales extend through two or more lots they shall be considered "conveyance swales." Conveyance swales shall be contained within an easement and excluded from the lot area calculation, per §
22-805, Subsection
1C.
I. Where trail easements are provided across private lots, a method
of physically delineating the trail easement shall be provided. Such
methods shall include shrubbery, trees, markers or other methods acceptable
to the Township.
J. There shall be a minimum distance of 50 feet, measured in the shortest
distance, between any proposed dwelling and any petroleum products
or natural gas transmission line.
K. Sanitary sewer lines shall be placed in the public street cartway
except where permitted in an easement by the Township Board of Supervisors
and the Township municipal authority.
[Ord. 3/29/1990B, § 804; amended by Ord. No. 22-05, 5/5/2022]
1. Minimal Grading. Grading shall be limited to the minimum amount of
disturbance of soil or natural topography.
2. Topsoil Protection. The topsoil that existed naturally on-site prior
to subdivision or land development shall be managed in the following
way:
A. In areas to be graded, the topsoil shall be stripped off and stockpiled
on site and only in accordance with the erosion and sediment (E &
S) control plan.
B. Following construction, the stockpiled soil shall be screened and
redistributed uniformly on site to a minimum depth of eight inches
and suitably stabilized by vegetation.
C. Any topsoil in excess of soil needed for reestablishment of eight
inches depth in areas of the site that will not be paved may only
be removed from the site provided that written authorization has been
obtained from the Township Engineer, and provided that said soil to
be removed has been documented and proven to be composed of clean
fill. Said soil to be removed shall not be resold, and all attempts
shall be made to relocate to a location within the Township, as specified
by the Township Engineer.
3. Grading. All permanent and temporary cutting, filling, grading, regrading,
and/or other forms of earthmoving activities shall be known as "grading"
and shall be conducted only in compliance with the standards as described
below.
A. All grading shall be set back from property lines a minimum of five
feet or a greater distance, as determined by the Township Engineer,
to prevent any adverse effects on adjacent properties.
B. No permanent excavation shall be made with a cut face steeper in
slope than 3:1. For steeper slopes, a soils report prepared by a qualified
engineer or geologist experienced in performing such studies and registered
in the Commonwealth of Pennsylvania shall be prepared to document
the soil stability.
C. Wherever grading will increase the volume or velocity of stormwater
flow toward a property line, the applicant shall install and maintain
drainage facilities sufficient to prevent adverse effects on the adjoining
property. The construction and operation of these drainage facilities
shall not cause any adverse effects on abutting properties.
D. Within the property proposed for development or along property lines,
where grading creates an abrupt drop-off in contrast to a previously
existing gradual change or where a wall is being installed, the applicant
shall be required to install a fence or other suitable protective
barrier.
E. A permit shall be required for grading operations. Permits shall
be issued by the Zoning Officer upon recommendation of the Township
Engineer for each tract, lot, parcel, or site which comprises a separate
operation, unrelated to or not contiguous with nearby grading proposed
or performed by the applicant. A permit shall not be required in the
following situations, however:
(1)
For an excavation that does not exceed 10 cubic yards total
material removed.
(2)
For a fill that does not exceed 10 cubic yards of material deposited.
(3)
For an excavation below finished grade for basements and footings
for a single-family detached or two-family dwelling, swimming pool,
or underground structure authorized by building permits, excavation
for a driveway for a single-family detached or two-family dwelling,
or the regrading of such excavated materials into the site from which
they were excavated.
F. Blocks and lots shall be graded to secure proper drainage away from
buildings and to prevent ponding of stormwater, except in detention/retention
areas.
G. Burying of trees, stumps or construction materials is prohibited.
Trees and stumps may be chipped or ground and spread on the site.
[Ord. No. 18-04, 7/23/2018; Ord. No. 18-05, 10/4/2018; as amended by Ord. No. 22-05, 5/5/2022]
1. For all dwelling units and buildings proposed to be provided with
basements or any type of structure below grade areas, the groundwater
elevation, perched water tables, or seasonally high groundwater elevation
(as indicated by the presence of redoximorphic features or other indicators
acceptable to the Township Engineer) within the building envelope
for the lot(s) where the dwelling units and buildings are proposed
to be constructed shall be identified and provided to the Township
with the preliminary and final plans. The groundwater elevation, perched
water table(s), and seasonally high groundwater elevation shall be
determined for each dwelling unit or building by on-site testing completed
prior to the preliminary plan submission. The test results shall be
certified by a qualified professional engineer, soil scientist, or
other professional who is acceptable to the Township.
2. Test excavations are subject to observation by a representative from
the Township. The Township is to receive notice of testing at least
72 hours' prior to the testing. The means of testing shall be approved
by the Township; such means shall not destroy the redoximorphic features
of the test area.
3. All basements and below grade areas (finished floor elevation) shall
be set a minimum of six inches above the perched water table, groundwater
elevation, or seasonally high groundwater elevation, whichever is
closest to the surface of the land.
4. The Township may require that an on-site inspection and testing be
conducted to determine if hydric soils and soils with hydric components
exist where a street is proposed, to determine if such soils may adversely
affect the proposed street(s). Streets within or on hydric soils or
soils with hydric components are prohibited.
[Ord. 3/29/1990B, § 806; as amended by Ord. 97-7, 10/13/1997, § 807; by Ord. No. 22-05, 5/5/2022; and by Ord. No. 22-08, 12/1/2022]
1. General.
A. All subdivision and land development plans shall include methods
to withhold and release stormwater at a controlled rate.
B. Properties shall be graded to ensure proper surface drainage away
from buildings and to promote the collection of stormwater in conveyance
systems per design. Minimum 2% slopes away from structures shall be
required.
C. The stormwater management system shall be designed in accordance
with all current and applicable Township stormwater management ordinances
and the Pennsylvania Best Management Practices Manual.
D. Existing natural stormwater drainage systems shall be preserved and
incorporated into the overall site stormwater management system.
E. New stormwater conveyance and control devices shall be designed to
be compatible with natural site conditions.
F. Maintenance of Stormwater Facilities. Prior to the granting of final
approval of any subdivision or land development plan, the Township
must be satisfied through contractual arrangements that all stormwater
facilities will be properly maintained. If all or a portion of the
facilities will be on property which will be conveyed to an individual
homeowners' association or any other eventual owner, the guarantees
must be in such a form that they will carry through to the new owners.
The approved post-construction stormwater management plan shall be
recorded with the Montgomery County Recorder of Deeds, along with
all maintenance requirements for the same.
G. Storm sewers, culverts and related installations shall be provided:
(1)
To permit unimpeded flow of natural watercourses and in such
a manner as to protect the natural character of the watercourses and
to provide regulated discharge.
(2)
To ensure adequate drainage of all low points along the line
of streets, sidewalks, trails, and bicycle facilities.
(3)
To intercept stormwater runoff along streets at intervals reasonably
related to the extent and grade of the area drained and to prevent
substantial flow of water across intersections.
H. Storm sewers, as required, shall be placed in the cartway of curbed
streets and parallel to the roadway shoulders of streets without curbs.
When located in undedicated land, with approval by the Township Board
of Supervisors, storm sewers shall be placed within an easement not
less than 20 feet wide.
I. Manholes shall be spaced not more than 300 feet apart on pipe sizes
up to and including 24 inches in diameter, and not more than 450 feet
apart for pipe sizes greater than 24 inches in diameter. Inlets may
be substituted for manholes, on approval by the Township Engineer,
at the same spacing as required for manholes. In no case shall inlets
or manholes be spaced more than 450 feet apart. Manholes or inlets
shall be provided at all changes of direction of storm sewer piping.
Storm manholes shall have a minimum opening of 30 inches. Manholes
or inlets shall be provided at all changes of direction of storm sewer
piping.
J. Manholes, inlets, headwalls and endwalls proposed for dedication
or located along streets or subject to vehicular traffic shall conform
to the requirements of the PennDOT, Bureau of Design, "Standards for
Roadway Construction," in effect at the time the design is submitted,
or as otherwise modified by New Hanover Township. Manhole covers shall
have the word "storm" cast in two-inch-high letters on the top of
the cover.
K. Stormwater roof drains and sump pumps shall not discharge water directly
onto a sidewalk or a street and shall be constructed to retain all
discharge wholly on the property except where such drainage can be
conveyed to a storm sewer system.
L. Drainage structures which drain watershed areas in excess of 1/2
square mile (320 acres), or which have a span of eight feet or more,
shall be designed for a maximum expected runoff as calculated using
the Soil Conservation Service Technical Release 55, Urban Hydrology
for Small Watersheds (less than 2,000 acres). The design storm shall
be a minimum fifty-year storm. A 100-year storm shall be used if the
structure will significantly affect the 100-year floodplain. A water
obstruction permit shall be obtained from the Pennsylvania Department
of Environmental Protection for all waterway openings prior to final
plan approval.
M. Headwalls and endwalls shall be used where stormwater runoff enters
or leaves the storm sewer horizontally from a natural or man-made
channel. PennDOT Type "DW" headwalls and endwalls shall be utilized.
The upstream endwall shall be provided with a slanted, hinged trash
rack. Flared end sections (FES) are recommended for all pipe inlets
and outlets with a pipe diameter equal to or less than 24 inches.
Endwalls with a height (top of wall to invert of pipe) greater than
three feet shall be faced with stone or an approved material and shall
include a safety fence at the top of the headwall consisting of a
split rail and wire mesh fence (three rails with a minimum height
of four feet).
2. Storm Sewer Design.
A. Storm Frequency.
(1)
Design Flow Rate. The storm drainage system shall be designed
for 100 years in all residential subdivision or land developments
where the gross density is less than six dwelling units per acre and
100 years in all other subdivisions or land developments, unless otherwise
specified by the Township Engineer. Rainfall intensity curves and
other hydraulic design data, provided by the Pennsylvania Department
of Transportation and/or Soil Conservation Service, shall be used
for design purposes. The design year peak flow rate into each inlet
shall be indicated on the stormwater drainage plan. The flow rate
shall be determined by the Rational Formula Q = CIA.
Where:
|
Q
|
=
|
Peak runoff rate measured in cubic feet per second (cfs)
|
C
|
=
|
Runoff coefficient-the coefficient of stormwater runoff includes
many variables, such as ground slope, ground cover, shape of drainage
area, etc.
|
I
|
=
|
Intensity-average rainfall intensity in inches per hour for
a time equal to the time of concentration
|
A
|
=
|
Area-drainage area in acres
|
B. Storm Duration.
(1)
A five-minute storm duration shall be used if the duration does
not result in a maximum expected discharge that exceeds the capacity
of a fifteen-inch pipe.
(2)
If a five-minute storm duration results in a pipe size exceeding
15 inches, the time of concentration approach shall be used in determining
storm duration.
C. Shoulders in Cut Areas (without swales).
(1)
Water flowing in the shoulder shall not encroach more than 2/3
the shoulder width during a ten-year-frequency storm of five-minute
duration.
(2)
The maximum velocity as determined by Manning's Equation shall
not exceed the allowable velocities as shown in Table 22-806-1 for the specific type of shoulder material.
(3)
Inlets shall be provided to control the shoulder encroachment
and water velocity.
D. Swales Adjacent to Shoulders.
(1)
When swales are provided in cut areas, the water shall not encroach
upon the roadway area during a ten-year-frequency storm.
(2)
The maximum velocity as determined by Manning's Equation shall
not exceed the allowable velocities as shown in Table 22-806-1 for the specific type of swale material.
E. Curbed Sections. The maximum encroachment of water on the roadway
pavement shall not exceed four inches in depth at the curbline during
a ten-year-frequency storm. Inlets shall be provided to control the
encroachment of water on the pavement.
F. Inlets.
(1)
When there is a change in pipe size in the inlet, the elevation
of the top of pipes shall be the same or the smaller pipe higher.
A minimum drop of two inches shall be provided at the inlet pipe invert
elevation and the outlet pipe invert elevation.
(2)
If the capacity of the shoulder, swale, curb section or depressed
median section is less than the inlet capacity, the shoulder, swale,
curb section or depressed median section capacity shall govern inlet
spacing.
(3)
Inlet capacities shall be based on a maximum flow of five cubic
feet per second.
G. Storm Pipes.
(1)
To facilitate the solution of Manning's Equation as applied
to storm pipes, charts are presented in "Design Charts for Open Channel
Flow," prepared by the U.S. Department of Commerce, which permit a
direct determination of the capacity of circular pipes. The hydraulic
grade line of flow in the storm sewer system shall result in at least
1.0 foot of freeboard in all inlets and manholes.
(2)
Where headroom is restricted, equivalent pipe arches may be
used in lieu of circular pipe.
(3)
Storm sewer pipes other than those used as roof drains, detention
basin underdrains, and street subbase underdrains shall have a minimum
diameter of 15 inches and be made of reinforced concrete pipe or HDPE.
Where installation conditions merit, structural calculations that
address the actual design requirements will be required. The minimum
diameter of storm pipe shall be 15 inches.
(4)
Inlets or manholes shall be placed at changes in vertical or
horizontal direction of pipe.
(5)
Pipe shall be designed with a slope such that the minimum velocity
of 2 1/2 feet per second will be attained; however, the slope
shall not be less than 0.5%.
(6)
All pipes shall be designed to have a minimum of 18 inches of
cover over the bell of the pipe.
(7)
Separate storm sewer system pipes shall enter and exit the sides
of inlet boxes and shall not encroach into the corners. A maximum
skew angle of 45° is permitted for all pipes.

1. General Provisions and Compliance.
A. No changes shall be made to the contour of the land, and no grading,
excavating, reconstruction of the topsoil, trees or other vegetative
cover of the land shall be commenced until such time as a plan for
minimizing erosion and sedimentation has been processed and reviewed
by the Township Planning Commission, the Montgomery County Conservation
District and the Board of Supervisors.
B. Approval of the Board of Supervisors of all preliminary and/or final
plans of subdivision and land development does not relieve the developer
of his obligation to execute the erosion and sediment control measures
as contained in this chapter.
C. When required, final approval of plans and specifications by the
County Conservation District for the control of erosion and sedimentation
shall be concurrent with the approval of the plans of subdivision
or land development, and become a part thereof. Final plans for minimizing
erosion and sedimentation as approved will be incorporated in the
agreement and development escrow requirements as required by the Township.
D. At the time a building permit is applied for, a review shall be conducted
by the Township Engineer to insure conformance with the plan as approved.
During construction, further consultative technical assistance will
be furnished, if necessary, by the Montgomery County Conservation
District. During the development phase, the Township Engineer, Township
Code Enforcement Officer or Soil Conservation Service representative
shall inspect the development site and enforce compliance with the
approved erosion and sediment control plans.
E. A subdivision or land development application shall comply with the requirements of Chapter
9, Grading and Excavating, Part
1, Soil Erosion, Sedimentation and Grading Control, as amended.
2. General Performance Standards.

Conservation District does not have standards and specifications for
erosion and sedimentation control, other known and commonly accepted
standards and specifications may be used as approved by the Township
Engineer.
B. The following measures to minimize erosion and sedimentation shall
be included where applicable in the control plan:
(1)
Stripping of vegetation, regrading or other development shall
be done in a way that will minimize erosion.
(2)
Development plans shall preserve salient natural features, keep
cut and fill operations to a minimum, and ensure conformity with topography
so as to create the least erosion potential and adequately control
volume and velocity of surface water runoff.
(3)
Whenever feasible, natural vegetation shall be retained, protected
and supplemented.
(4)
The disturbed area and the duration of exposure shall be kept
to a practical minimum, but shall not exceed 20 days. Areas disturbed
between October 15 and April 15 shall be stabilized by placement of
sod or other means acceptable to the Township.
(5)
Temporary vegetation and/or mulching shall be used to protect
all exposed areas during development.
(6)
The permanent (final) vegetation shall be installed immediately
upon spreading of topsoil in the development.
(7)
Provisions shall be made to accommodate effectively the increased
runoff caused by changed soil and surface conditions during and after
development within and around the site. Where necessary, the rate
of surface water runoff shall be mechanically slowed.
(8)
Sediment in the runoff water shall be trapped until the disturbed
area is stabilized by the use of debris basins, sediment basins, silt
traps or similar measures.
3. Site Grading for Erosion Control. In order to provide more suitable
sites for building and other uses, improve surface drainage and control
erosion, the following requirements shall be met:
A. All lots, tracts or parcels shall be graded to provide proper drainage
away from buildings and dispose of it without ponding. All land within
a development shall be graded to drain and dispose of surface water
without ponding, except where ponding (detention basins, etc.) is
part of the stormwater management plan for the site.
B. Concentration of surface water runoff shall be permitted only in
swales, watercourses or detention basins. Subject to the approval
of the Township Engineer, swales shall be sodded, utilize jute matting
or other similar measures to insure establishment of ground cover.
C. Grading shall in no case be done in such a way as to increase stormwater
runoff and/or velocity of stormwater runoff onto the property of another
landowner.
D. During grading operations, necessary measures for dust control must
be exercised.
E. Grading equipment will not be allowed to cross streams. Provisions
shall be made for the installation of temporary culverts and bridges.
F. Tire cleaning areas shall be provided and maintained at each point
of access to the development site.
4. Excavations and Fills.
A. No excavation shall be made with a cut face steeper than three horizontal
to one vertical, except under one or both of the following conditions:
(1)
The material in which excavation is made is sufficiently stable
to sustain a slope of steeper than three horizontal to one vertical.
A written statement to that effect from an engineer licensed by the
Commonwealth of Pennsylvania and experienced in erosion control shall
be submitted to the Township Engineer for approval. The statement
shall affirm that the site has been inspected and the deviation from
the slope will not result in injury to persons or damage to property.
(2)
A concrete, masonry or other approved retaining wall constructed
in accordance with appropriate standards is provided to support the
face of the excavation.
B. Edges of slopes shall be a minimum of five feet from property lines
or right-of-way lines of streets in order to permit the normal rounding
of the edge without encroaching on the abutting property.
C. Adequate provisions shall be made to prevent surface water from damaging
the cut face of excavations and the sloping surfaces of fills.
D. Cut and fill shall not endanger adjoining property.
E. Fill shall be placed and compacted so as to minimize sliding or erosion
of the soil.
F. Fills shall not encroach on natural watercourses or constructed channels.
G. Fills placed adjacent to natural watercourses or constructed channels
shall have suitable protection against erosion during periods of flooding.
5. Responsibility.
A. Whenever sedimentation is caused by stripping of vegetation, regrading
or other development, it shall be the responsibility of the person,
corporation or other entity causing such sedimentation to remove it
from all affected surfaces, drainage systems and watercourses on and
off-site, and to repair any damage at his expense as quickly as possible.
B. Maintenance of all drainage facilities and all watercourses, both
existing and proposed, within any proposed subdivision or land development
shall be the responsibility of the developer until such time as one
of the following is accomplished:
(1)
An easement for these facilities is offered for dedication by
the developer and is accepted by the Township; it shall then be the
responsibility of the owner.
(2)
If an easement acceptable to the Township is established, but
not dedicated to the Township, the maintenance shall then be the responsibility
of the individual lot owners over whose property the easement passes.
For land developments, the maintenance shall be the responsibility
of the owner.
(3)
A homeowners' association or other approved legal entity, approved
by the Township, assumes the responsibility for the maintenance of
the development, including the maintenance of the watercourses and/or
drainage facilities.
C. It is the responsibility of any person, corporation or other entity
doing any work on or across a stream, watercourse or swale or upon
the floodplain or right-of-way during the period of work to return
it to its original or equal condition after such activity is completed.
D. No person, corporation or other such entity shall block, impede the
flow of, alter, construct any structure or deposit any material or
thing or perform any work which will affect normal or flood flow in
any communal stream or watercourse without having obtained prior approval
from the Township and/or Department of Environmental Protection, whichever
is applicable.
E. Each person, corporation or other entity which makes any surface
changes shall be required to:
(1)
Collect onsite surface runoff and control it to a point of discharge
into the natural watercourse of the drainage area.
(2)
Control existing offsite runoff through his development by designing
it to adequately control all upstream runoff.
(3)
Provide and install at his expense, in accordance with Township
requirements, all drainage and erosion control improvements (temporary
and permanent) as required by the approved erosion and sediment control
plan.

templates are required to verify that the largest emergency vehicle
serving the Township, design vehicle for the site, and any other delivery
vehicles can turn around within the cul-de-sac street without interfering
with any vehicles parked within the cul-de-sac street, if on-street
parking is permitted within the cul-de-sac street. If the paved radius
of the cul-de-sac street is increased, the radius of the right-of-way
must also be increased by the same amount and a center curbed landscape
island provided at the discretion of the Township Engineer. The center
curbed landscape island shall then be owned and maintained by one
of the lot owners or a community association approved by the Board
of Supervisors.
C. As an alternative to a fully paved cul-de-sac, the center of the
cul-de-sac may be provided with a planted island which shall be owned
and maintained by one of the lot owners, or a community association
approved by the Board of Supervisors. The cul-de-sac shall be provided
with a paved cartway having an outer paving radius of 50 feet and

T-Intersections shall be laid out to prevent interlocking left-turn
movements.
3. Angle of Intersections.
A. All intersection approaches shall be designed at right angles unless
sufficient reason exists to justify a lesser angle. However, no angle
shall be less than 75° for intersections with arterials or collector
roads and 70° for intersections between local access streets,
measured at the centerlines of the intersections.
B. Where angled intersections are used, it is preferable to design them
so that the heavier traffic flow will make the turn which is greater
than 90°, rather than the turn which is less than 90°.
4. Corrective Changes to Existing Intersections. When existing streets
intersect at odd angles or have more than four approaches, the applicant
shall make corrective changes to bring the intersection into compliance
with this chapter, as required by the Supervisors, who shall first
seek the advice of the Township Engineer and Planning Commission and
other technical advisors or agencies, as appropriate. For state and
county highways, corrective changes shall comply with the requirements
of the appropriate agency.
5. Waiver of Corrective Changes. The Supervisors may waive the above
requirements for corrective changes under one or more of the following
conditions:
A. When changes made on the applicant's land will not improve the intersection's
deficiencies.
B. When other road improvements are already planned which would correct
the problem without any corrective action required of the applicant.
C. When not required by PennDOT or Montgomery Count where the intersections
are under their jurisdiction.

utilized by the Township or by the largest design vehicle anticipated
to use a site, whichever is greater, which will be verified with truck
turning templates for all movements.
B. All radii specified herein must be increased if fire trucks or other
emergency vehicles would have difficulty with ingress or egress as
determined by the Township Fire Marshall. Any increase in radii shall
be reviewed by the Township Traffic Engineer. The applicant is required
to provide turning templates based on the largest firetruck or emergency
vehicle utilized by the Township or by the largest design vehicle
anticipated to use a site, whichever is greater, for all turning movements
at an intersection.
7. Intersection Spacing. Proposed streets on opposite sides of or the

[Added by Ord. No. 22-05, 5/5/2022]
The standards of this section regulate the sight distance evaluation,
which is required in conjunction with all land development applications
for proposed residential and nonresidential driveways intersecting
existing and/or proposed residential streets, as well as the intersections
of new residential and/or nonresidential streets with existing and/or
proposed streets.
1. Applicability. A sight distance evaluation is required for all new
driveway and local roads that create new intersections with existing
streets for all land development applications. Additionally, where
in the opinion of the Township's Traffic Engineer there are concerns
regarding the ability of a proposed new driveway or street that intersects
with another proposed new street to provide for safe sight distance,
an evaluation of the sight distance may then be requested.
2. Purpose is as follows:
A. To permit reasonable access to private properties and guard the general
public's right to safe and efficient travel along public roads by
requiring sufficient sight distance at street and driveway intersections
with public streets.
B. To identify safe and preferable locations for vehicular access using
the driveway or approach regulations that permit access to public
streets, while controlling the location, number and physical layout
of access points.
C. To reduce the degree of interference on traffic flow and/or safety
caused by a proliferation of driveway and/or street intersections
by minimizing the total number of access locations.
D. To encourage subdivisions and land developments to use new local
access roads for access rather than strip new lots and access driveways
along higher classification roads.
E. To encourage or require, as appropriate, the use of a shared access
point, paired driveways, or new local access streets for vehicular
access to proposed lots and/or development.
F. To encourage the use of flexible lotting for visual benefits, preservation
of natural features, and/or rural character where they may contribute
to safe and efficient vehicular access.
G. To encourage planning for entire tracts, blocks and superblocks rather
than piecemeal subdivision and/or development.
3. Minor Sight Distance Analysis. A minor access analysis shall be the
minimum required for all subdivision and/or land development plans.
The following information shall be shown and labeled on the applicant's
subdivision and/or land development plan:
A. Provide a table that documents the posted speed limit and/or 85th
percentile speed and approach grades that the minimum safe sight distance
is based upon along with the source of the safe sight distance for
all egress movements looking to the left or right from the new proposed
driveway or intersection along with the safe sight distance for a
left-turn ingress vehicle looking ahead and for a vehicle approaching
from the rear. A driver eye height of 3.5 feet is to be used per PennDOT
Form M950-S. For left-turning vehicles entering a driveway and/or
intersecting road, the distance for a vehicle approaching from the
rear is based on the location of the taillights of the vehicle and
the height of the taillights as two feet. The table shall then document
the existing available sight distance and any remedies necessary to
achieve the minimum safe stopping sight distance.
B. Safe Stopping Sight Distance. For each existing or proposed driveway
or street intersection, the applicant's plan shall identify the required
and available safe stopping sight distance for the subject road in
compliance with current PennDOT standards for driveways and local
roads for new residential or nonresidential street intersections in
accordance with Title 67 Chapter 441, as amended, the latest edition
of the PennDOT Design Manual, or the latest edition of AASHTO's A
Policy on Geometric Design of Highways and Streets.
C. Sight Distance Obstructions. The plan shall identify all obstructions
that interfere with the required sight distance and label them as
correctable (such as vegetation and obsolete, replaceable or moveable
structures) or not correctable (such as road grades or curvature or
structures to be retained). If items are not correctable, then the
applicant must relocate the driveway or intersection to another location
within the site frontage where safe sight distance can be achieved.
D. Review by Township Traffic Engineer. The Township Traffic Engineer shall review the submitted information in accord with current standards and accepted engineering principles as referenced in Subsection
3C.
E. Acceptable Sight Distance. If the available sight distance is acceptable
or will be corrected by the applicant to be acceptable, then no further
analysis is required. The applicant shall guarantee correction of
obstructed sight distance as required by the Township Traffic Engineer
and maintenance of required sight distance in a manner acceptable
to the Board of Supervisors.
F. Unacceptable Sight Distance. If the available sight distance is unacceptable,
the applicant shall be required to propose measures to provide acceptable
sight distance or propose alternative access locations with acceptable
sight distance.
G. Severely Limited Sight Distance. For any proposal where the Township
Traffic Engineer determines that existing conditions severely limit
sight distance, the applicant shall be required to conduct a major
sight distance analysis.
4. Major Sight Distance Analysis. When required in accord with §
22-821, Subsection
3G, herein, the applicant shall conduct an on-site survey along the entire frontage of the subject property to identify the physical characteristics that impede sight distance and/or suitable vehicular access, and provide the following information concerning those characteristics on the submitted plans:
A. Horizontal Plan. The horizontal plan information may be shown on
the subdivision and/or land development plan or on a separate horizontal
plan and shall show the following at a scale not exceeding 50 feet
to the inch:
(1)
Legal and ultimate rights-of-way and centerline.
(2)
Existing cartway and shoulder widths and conditions.
(3)
Existing contours drawn at two-foot intervals.
(4)
All existing natural and man-made features within the ultimate
right-of-way on the subject property's side of the street.
(5)
Existing natural and man-made features on the subject property,
beyond the ultimate right-of-way, that may impede street or driveway
access into the site, such as embankments, steep slopes, watercourses,
floodplains, wetlands, vegetation, buildings, walls or other structures.
(6)
Any other information needed to establish sight distances along
the road frontage.
(7)
Minimum safe stopping sight distance required by PennDOT standards
for the road being accessed, regardless of road jurisdiction.
(8)
Maximum sight distance available from each driveway or street
intersection proposed.
B. Profiles. Profiles shall be drawn along the sight distance line at
a horizontal scale not exceeding 50 feet to the inch, and vertical
scale of two, four or five feet to the inch, whichever is most appropriate,
to identify obstructions and limitations to sight distances:
(1)
Road centerline, with road grades indicated, for left-turn ingress
movements looking ahead or for a vehicle approaching from the rear.
(2)
Ten feet from the edge of the existing or proposed cartway for
new driveway intersections, 15 feet or at the location of the proposed
stop bar, whichever is greater, from the existing or proposed cartway
for new residential and/or nonresidential street intersections. The
line of sight will then be drawn from these locations where a vehicle
would be for exiting the driveway or new street to the location in
the intersecting roadway where an approaching vehicle would be located.
The distance from the centerline of the egress vehicle to the approaching
vehicle as measured along the roadway must then meet the minimum safe
sight distance requirements.
5. Adjustments to Existing Street and Driveway Intersections. When the
minor or major sight distance analysis shows that the designs and/or
locations of existing street and/or driveway intersections do not
satisfy sight distance, spacing, or other safety-related considerations
of this chapter, the applicant shall modify or relocate the existing
intersections to comply with the standards herein.
6. Plan Approval. No plan that requires a major sight distance analysis
shall be approved unless it satisfies the following:
A. Required Information. All information required for the major sight
distance analysis shall be provided on the plans as verifiable graphic
evidence and explanatory notes.
B. Acceptable Sight Distance. The existing and proposed street and/or
driveway intersections shall provide at least the minimum required
safe stopping sight distances.
C. Resolution of Other Issues. The applicant's plan shall otherwise
resolve all sight distance and vehicular access issues identified
by the Township Traffic Engineer's review of the major sight distance
analysis in a manner consistent with the standards herein regarding
intersection spacing, intersection design, and alignment of streets
and driveways.
7. Clear Sight Distance Triangles.
A. Clear sight triangles shall be required to be maintained along all
approaches to all street intersections, and all intersections of driveways
with streets, in compliance with the standards herein.
B. Approach sight triangles shall be provided for all intersections
with existing and/or proposed streets or driveways to ensure vehicles
on the major street of intersecting streets are able to view the vehicle
waiting to enter the traffic stream.
C. Within the area of clear sight triangles, obstructions to visibility
shall not be permitted within the following ranges of height:
(1)
For all streets, between 2 1/2 feet and 12 feet above the
edge of paving.
(2)
Any plant materials placed within clear sight triangles shall
be properly maintained to continually comply with the height restrictions
herein. If not properly maintained, the Township reserves the right
to trim and/or remove the plant materials, upon due notice to the
property owner. The property owner shall be responsible for reimbursing
the Township for any costs associated with this type of maintenance
activity.
(3)
The following items may be permitted within a clear sight triangle
based upon review and recommendation of the Township Traffic Engineer:
(a)
One private sign or lamppost, provided that the post does not
exceed one foot square or diameter, and that the sign or lamp itself
is above the top height limitation.
(b)
One shade tree, provided that, as the tree matures, its lower
branches will be removed within the restricted height ranges and the
diameter of the trunk does not exceed 12 inches.
(c)
Existing shade trees, provided that the lower branches are removed
within the restricted height ranges and that the size, number and
arrangement does not impede adequate visibility. The Board of Supervisors
may require removal of one or more trees as necessary to provide adequate
visibility.
(d)
Where street or driveway grades drop off from an intersection,
the Township Traffic Engineer may modify these requirements as necessary
to improve visibility at the intersection.
D. Clear sight triangles shall be measured in each direction along street
centerlines, from their point of intersection in accordance with Figure
2 for the major street and 20 feet back from the edge of the travel
lane or edge of road along the minor street or nonresidential driveway,
whichever distance is greater. These standards shall also apply to
all nonresidential driveways that are anticipated to carry over 10
trips per day. The sight distance along the main roadway shall be
based upon the latest PennDOT Design Manual or latest edition of AASHTO's
A Policy on Geometric Design of Highways and Streets.
E. Clear sight triangles shall be measured in each direction along street
centerlines, from their point of intersection in accordance with Figure
2 for the major street and 10 feet back from the edge of the travel
lane or edge of road along the residential driveway, whichever distance
is greater. These standards shall also apply to all nonresidential
driveways that are anticipated to carry 10 or less trips per day.
The minimum safe sight distances, referenced in the current the PennDOT
standards from Title 67, Chapter 441, or as amended, shall apply for
residential driveways.
[Ord. 3/29/1990B, § 818; as amended by Ord. 07-02, 3/26/2007, § 4; and by Ord. No. 22-05, 5/5/2022]
1. Applicability. A traffic impact study shall be required, as established
by this section, for all preliminary subdivision and land development
applications under the Subdivision and Land Development Ordinance
when the land development is projected to generate 200 new ADT (average
daily trips), or 20 or more new peak hour trips, as established in
the most recent edition of the Institute of Transportation Engineers
(ITE) publication, Trip Generation Manual.
A. Separate applicability standards are established, as applicable,
in the Township Zoning Ordinance related to conditional uses, special exceptions, or any
other request for rezoning.
B. The requirements of this section may be modified by the Board of
Supervisors, or the Zoning Hearing Board if applicable, upon coordination
with the Township Traffic Engineer when specific requirements are
determined not to be applicable to the preliminary subdivision or
land development application.
2. Study Waiver. The Board of Supervisors may waive the requirements
of a traffic impact study and require the applicant to contribute
to the Township a sum equal to the cost of a study as determined by
the Township to be used for general Township traffic needs.
3. Joint Studies. When two or more developments are located in the same
general area, the Board of Supervisors, at its discretion, may require
the applicant to prepare a joint study or request a fee in lieu of
an individual study, so the Township can then sponsor a joint traffic
study. The cost of the joint study shall be shared among the applicants,
and the study would include a fair-share cost estimate of any recommended
off-site roadway and/or intersection improvements, as well as an assessment
of each development's access(es).
4. Preparation and Review. The traffic study shall be conducted under
the supervision of a professional engineer currently registered in
the State of Pennsylvania, preferably one possessing a professional
traffic operations engineer certificate, as all studies must be signed
and sealed. The developer shall reimburse the Township for reasonable
fees and expenses incurred by the Township Traffic Engineer for the
review of the developer's traffic impact study and plans.
5. Time of Submission. The traffic impact study shall be submitted to
the Township and Township Traffic Engineer as part of the preliminary
subdivision and land development application. The submission of the
preliminary plan application shall be deemed incomplete if the required
traffic impact study is not included in the submission.
6. Purpose. A traffic impact study shall enable the Township to assess
the likely traffic impact of a proposed development on the various
components of the transportation system. The requirements of this
section are separate from, but function in parallel with, the Township's
adopted Act 209 (Transportation Impact Fee) Ordinance and Transportation
Capital Improvement Program. The study shall: (1) address the safe
and efficient circulation of both vehicles and pedestrians on the
site; (2) identify the impacts of development traffic at the site's
accesses to public roads within the Township and provide appropriate
mitigation for safe and efficient movement of vehicles and pedestrians
thereof; and (3) identify the development's impact on the surrounding
roadway network for the purposes of establishing the basis of its
transportation impact fee for mitigation of its impacts, or in lieu
of the fee, making the necessary improvements thereof, which shall
be at the discretion of the Board of Supervisors.
7. Definitions. The following terms or phrases shall have the meanings
indicated when used in this section:

site. New trips are calculated as total trips generated by the development
net of pass-by trips (i.e., trips already on the roadway network)
to/from the development.
QUEUE ANALYSIS
An analysis that identifies the maximum stacking of vehicles
in each traffic lane, measured in feet. The analysis shall utilize
a methodology acceptable to the Township and/or the Pennsylvania Department
of Transportation and Montgomery County Roads and Bridges.
STUDY AREA
The study area shall be the area of land, and specific roadways
and intersections, within the Township that are likely to be affected
by the development.
TRIP GENERATION
The total count of trips to and from the subject development
per unit of land use (i.e., dwelling unit, square footage, etc.) as
established by the most recent edition of ITE's Trip Generation Manual.
For land uses not listed in this publication, or for those land uses
with limited available trip generation data, the applicant's traffic
engineer shall seek guidance from the Township prior to completion
of the study. For applications involving an expansion or relocation
of an existing facility, actual trip generation characteristics of
the existing land use may be utilized, as appropriate, and subject
to acceptance by the Township. Other local sources of trip generation
data may be acceptable, subject to the approval of the Township.
VOLUME/CAPACITY ANALYSIS

to its capacity. The methodology for the analysis shall adhere to
the most recent edition of the Highway Capacity Manual, or other methodology
acceptable to the Township, as well as the Pennsylvania Department
of Transportation (PennDOT) and Montgomery County Roads and Bridges
when intersections with their roadways are included in the study.
8. Scope of Study Area. Prior to the initiation of the traffic study,
the applicant shall receive approval of the scope of the study area
from the Township before proceeding. The minimum requirements of the
scope of the traffic study area potentially affected by the proposed
development (inclusive of specific roadways and intersections) are
as follows:
A. Development Driveways (Accesses). All existing and proposed driveways
(accesses) for the development intersecting public Township, PennDOT,
or county roadways, plus adjacent roadways, intersections, and driveways
along the applicant's property, or adjacent properties, which may
be directly affected by vehicular and pedestrian traffic from the
development.
B. Supplemental Study Area for Developments Within a Designated Transportation
Service Area.
(1)
Nonresidential Developments with Significant Deviation in Density,
Intensity, or Trip Generation from Land Use Assumptions Report. If
the Township determines that the applicant's development falls in
this category, the scope of study area shall minimally include all
major roadways and intersections within the Transportation Service
Area where the development is located which accommodates 10% or more
of development traffic and/or 100 or more new peak hour trips. The
applicant, or its traffic engineer, shall submit a preliminary analysis
of the study area affected by this development to the Township and
its Traffic Engineer for agreement and approval before proceeding.
(2)
Any Development which Generates More than 1,000 New Peak Hour
Trips. The scope of study area shall include all major roadways and
intersections outside the Transportation Service Area where the development
is located, but within the municipal boundaries of the Township which
will accommodate 10% or more of development traffic and/or 100 or
more new peak hour trips. The applicant, or its traffic engineer,
shall submit a preliminary analysis of the study area affected by
this development to the Township and its Traffic Engineer for agreement
and approval before proceeding.
9. Voluntary Traffic Impact Study. At any time, an applicant for a proposed
development may prepare and submit a traffic study to (1) substantiate
its opinion that the development's trip generation is different than
that established by the Township for purposes of determining the development's
Transportation Impact Fee, in accordance with its adopted Act 209
Ordinance; or to (2) justify allocation of its impact fee to specific
projects contained in the Township's adopted Capital Improvement Plan,
or to otherwise implement transportation capital improvements not
contained in the adopted Capital Improvement Plan. Please note that
the approval by the Board of Supervisors is required for the use of
any impact fees used for projects not indentified in the adopted Capital
Improvement Plan.
10. PennDOT and/or Montgomery County Roads and Bridges Traffic Impact
Study Requirements. Nothing in this section relieves the applicant
for a development which will access a state highway within the Township
to comply with the Department's Policies and Procedures for Transportation
Impact Studies or for access along a county highway from the requirements
of Montgomery County Roads and Bridges. The Township urges the applicant
to coordinate its scope of any traffic study required by the Township,

D. Future Conditions without the Proposed Development. An evaluation
of the anticipated future traffic volumes, and the ability of the
roadway network to accommodate area traffic without the proposed development,
shall be provided for the approved study area roadways and intersections.
The total future traffic shall be calculated and consist of the existing
traffic expanded to the greater of the following: a three-year traffic
data projection beyond the existing year when the counts were conducted
or the year of the anticipated full build-out of the proposed development.
If phasing is planned, then an analysis of all phases must also be
provided to determine the appropriate level of mitigation for each
phase. This evaluation shall include the following:
(1)
Peak hour traffic volumes shall be projected for the full build-out
year or phased years(s) based on traffic growth information compiled
by PennDOT, DVPRC, or the County for the Township. Projected traffic
volumes shall also include anticipated traffic growth associated with
other significant area proposed developments which will be completed,
or partially completed, by the design year(s), or developments under
construction. All assumptions and methodologies utilized to forecast
the future traffic volumes shall be clearly documented. Figures shall
be provided in the report illustrating the peak hour turning movement
traffic volumes for this future condition, and trip generation, distribution,
and assignment assumptions shall be provided as well for all other
development projects.

E. Development Trip Generation. Estimates of vehicle trips generated
by the proposed development shall be completed for the design year(s)
peak highway and development specific peak generation hours, and on
a daily basis. A table shall be provided which clearly identifies
total trips and total new trips. Pass-by trip and internalization
assumptions, as applicable, should be clearly identified and discussed
in the study including the reference source and any corresponding
calculations. Current versions of ITE's Trip Generation Manual and/or
Trip Generation Handbook should be utilized to determine the total
trip generation for the site, as well as any internal or pass-by trip
reductions. Trip generation estimates based upon alternative sources
(e.g., local counts of similar uses) should be clearly documented,
including reasons for their use versus use of ITE published data.
It is recommended that local trip generation data be submitted for
review by the Township in advance of utilizing it within any study.
F. Development Traffic Distribution and Assignment. Traffic volumes
generated by the proposed development shall be distributed and assigned
throughout the study area for each of the study peak hours. Documentation
of all assumptions used in the distribution and assignment of traffic
shall be provided.
G. Future Conditions with the Proposed Development and No Improvements.
In order to access the magnitude of the proposed development's impact

the site access(es), an analysis shall be completed for the design
year(s) with development of the site and no improvements.
(1)
Daily and peak hour traffic volumes shall be projected for the
full build-out year(s). Projected traffic volumes shall be calculated
by adding the assigned development trip generation to the future traffic
volumes with development on the study roadway and intersection network,
including the site access(es). Figures shall be provided in the report
illustrating the resultant peak hour traffic volumes with the proposed
development with proposed improvements, including all turning movements.

intersections including the site access(es). The level-of-service
results shall be presented graphically.
(3)
A queuing analysis (maximum queues) shall be performed during
the peak highway and development hours for each study intersection,
including the site access(es). The results of the queuing analysis
shall be presented graphically, and the available storage lengths
for all existing and proposed intersection approach lanes shall be
identified to determine the adequacy of these facilities to accommodate
the anticipated future vehicular traffic queues.
(4)
All movements at all site accesses shall function at levels-of-service
D or better with future with-development traffic volumes. If signalized,
the intersection(s) overall shall also function at level-of-service
D or better overall with all lane groups also operating at LOS D or
better.
(5)
A lane warrant evaluation shall be completed for all proposed
accesses to determine if separate left- and/or right-turn lanes are
warranted, which shall be based upon the requirements of the latest
PennDOT Publication 46 or as amended. If a lane is warranted, the
length is to follow PennDOT Publication 46 recommendation for storage
length with a minimum seventy-five- to ten-foot bay taper and appropriate
transitional area following the latest PennDOT Design Manual criteria,
as amended.
H. Mitigation Criteria. Based on the results of the future conditions
with the proposed development and no improvements, the need for mitigation
improvements will then be evaluated further based upon the following
criteria:

Intersections and/or Roadways Involving State Highways. At all
state highways and intersections involving state highways, the need
for mitigation will be based on PennDOT's criteria as contained in
their Policies and Procedures for Transportation Impact Studies and
shall follow PennDOT's mitigation policy. For all county highways
and intersections involving county highways, Montgomery County Roads
and Bridges criteria is to be used.
(2)
Township-Maintained Intersections and/or Roadways. Improvements
at study area intersections and/or roadways, other than the proposed
site access(es), shall be presented for future with-development traffic
volumes as noted below:
(a)
If the future without-development conditions function at LOS
D or better overall and on all individual lane groups, then the future
with development conditions shall be mitigated to operate at level-of-service
D or better overall and on lane groups.
(b)
If future without-development conditions function at level-of-service
E overall or on any individual lane groups, then improvements shall
be identified such that future with-development level-of-service conditions
will be no worse than the without-development level-of-service E.
(c)
If future without-development level-of-service conditions are
F, future with-development level-of-service F conditions shall have
no greater volume/capacity ratios and delays than future without-development
conditions.
(d)
If the existing storage lengths or spacing between intersections
is inadequate to accommodate the anticipated vehicular queue with
development of the site, then appropriate mitigation measures shall
be provided, which would include the extension of existing storage
areas for separate left- and/or right-turning lanes or the provision
of new lanes. The design of separate left- and/or right-turn lanes
shall follow the latest PennDOT Publication 46 requirements, as amended.

(b)
The necessity for auxiliary turn lanes at each site access intersection
shall be identified based on the current design guidelines of the
Pennsylvania Department of Transportation;
(c)
All access points and pedestrian crossings shall be examined
as to the need for, and feasibility of, installing traffic signals
or other traffic control devices, pursuant to the guidelines and traffic
signal warrants of PennDOT. Additionally, for pedestrian crossings
at locations where traffic does not stop or a traffic control signal
is not being installed, the applicant shall complete a mid-block pedestrian
crossing study following PennDOT Publication 46 requirements for "Unsignalized
Mid-Block Crosswalks" or as amended;
(d)
Design recommendations on study roadways and at other study intersections shall incorporate the comparable Township, PennDOT, and/or Montgomery County Roads and Bridges design guidelines as Subsection
11I(2)(a) through
(c) addresses for the site access(es).
J. Future Conditions with the Proposed Development and Recommended Improvements.
A description of the adequacy of the study area roadways and intersections
to accommodate future traffic with development of the site with proposed
improvements shall be provided. The analysis shall be completed for
each study peak hour for the development completion year, and any
interim years, if development phases are proposed. The evaluation
shall include the following for any study area intersections and/or
roadways where mitigation is required:
(1)
A volume/capacity analysis based on future with-development

identified to determine the adequacy of these facilities to accommodate
the anticipated future vehicular traffic queues.
K. Conclusions and Recommendations. This last report section shall include
a matrix comparing levels of service (overall and by lane group) on
each study roadway, site access intersection, and other study intersections,
if appropriate, for existing conditions, future conditions without
development, and future conditions with development with improvements.
If the development is to be phased, all interim future conditions
should be summarized. A summary of all recommended improvements should
also be provided, including the party responsible for each. Appropriate
summaries should be provided indicating that all future vehicular
queues can be provided within existing intersection approach lane
limits or with the future improvements to be provided by the applicant
or others.

D. Understory or ornamental trees or large shrubs may be deciduous or
evergreen and shall have a distinctive ornamental characteristic such
as prominent flowers, fruit, habitat, foliage, or bark.
E. Small shrubs may be evergreen or deciduous.
3. Minimum Soil Volumes. The registered landscape architect shall provide
details on the site plan that show a longitudinal section and depth
of planting areas 1,000 square feet and under in area demonstrating
compliance with minimum soil volume standards.
A. The following minimum soil volume per tree shall apply when such
plant is proposed in any planting areas 1,000 square feet and under
in area:
(1)
Small canopy or evergreen tree: 600 cubic feet.
(2)
Medium canopy tree: 900 cubic feet.
(3)
Large canopy tree: 1,200 cubic feet.
B. Planting Soil Composition. Planting soils shall be a loam soil capable
of supporting a healthy vegetative cover, which is amended with composted
organic material, such as mushroom compost or leaf mulch, resulting
in an organic amended soil containing 20% to 30% organic material
(compost), and 70% to 80% topsoil screened of rocks, sod, and debris.
The minimum depth of the planting soil shall be 30 to 36 inches depending
on the size of the individual planting. A soil improvement detail
and notes, including the removal of all construction debris and existing
compacted soil and the proposed soil improvement mix, should be provided
with the landscape plan. Ensure trunk flare sits above finished grade;
compact soil below root ball as necessary.
C. Alternative Methods. The alternative methods are for limited street
planting areas, where required soil volumes are unattainable without
implementing these methods. If the minimum soil volumes cannot be
achieved, as determined by the Township Engineer, the following alternative
options may be utilized:
(1)
Structural Soil Composition (Figure 3). Structural soil shall
be a mix of 80% AASHTO No. 57 stone and 20% loam soils. Such soil
may be used to supplement planting soil volume, provided it satisfies
all of the following conditions:
(a)
Structural soils shall be used under impervious paving where the tree planting area is surrounded by paving for the purpose of expanding the soil volume to meet minimum soil volumes specified §
22-825, Subsection
3A, above.
(b)
Structural soils shall be entirely below pavement areas and
shall not be exposed at the surface.
(c)
Structural soils are located adjacent to planting soils.
Figure 3: Structured Soil Composition
|
(2)
Suspended Pavements System (Figure 4). A tree/pavement support
system may be utilized that supports the weight of the pavement and
improves the urban tree health. The support structure, as well as
a pervious flexible pavement, creates a void space for increased tree
root/soil volume. The space shall be filled with a combination of
structural soils and native excavated soil, provided that it's quality
material, or a specified soil mix.
Figure 4: Suspended Pavements System
|
(3)
Shared Root Zone Areas or Linear Tree Planting (Figure 5). The
system should allow the root systems of adjacent trees to join and
share soil space where available. Structural soils shall be utilized
beneath the sidewalk or hardscape, as noted above. The following minimum
soil volume per tree shall apply when such plants are shared any planting
areas.
(a)
Medium canopy tree: 750 cubic feet when clustered.
(b)
Large canopy tree: 900 cubic feet when clustered.
Figure 5: Shared Root Zone Areas or Linear Tree Planting

that could endanger safety such as unstable limbs shall be removed
and the plant materials shall be replaced if necessary. It shall be
the responsibility of all property owners to maintain all plantings
and architectural elements to ensure a safe environment.
B. Maintenance guidelines for all plantings should be developed by the
planting plan designer to be used by grounds maintenance personnel.
[Added by Ord. No. 22-05, 5/5/2022]
1. Intent. The intent of this section is as follows:
A. Promote and induce well-designed and sustainable parking lot design
and retrofit designs which produce environmental benefits.
B. Incorporate appropriate native plants into the suburban environment
to promote greater landscape resiliency, to create healthy ecosystems,
and to enhance natural environments of the Township.
C. Integrate stormwater management and landscape design by the use of
plants to promote detention, treatment, infiltration and groundwater
recharge of rainwater.
D. Shade paved surfaces to mitigate the urban heat island effect by
planting large canopy trees with effective green space and using paving
surfaces which minimize heat absorption.
E. Improve the performance of existing parking lots in an equitable
manner when a redevelopment or retrofit is proposed.
F. Provide effective landscape buffers for visual screening and noise
abatement of vehicular uses and parking, while enhancing the wildlife
habitat provided by trees and natural landscape.
2. Applicability. Unless otherwise expressly stated, the interior landscape
and buffer requirements of this section shall apply to any of the
following:
A. The construction or installation of new vehicular use areas;
B. The expansion of existing vehicular use areas, if such repair, rehabilitation,
or expansion would increase the area of the vehicular use area by
more than 20% or by 10 spaces, whichever is greater;
C. The existing vehicular use areas which are accessory to an existing
principal building, when such building or any portion thereof is expanded
or enlarged, provided that the gross floor area/building footprint/area
is increased by at least one of the following amounts:
(1)
25% of the existing building footprint; or
(2)
Eight thousand square feet of new floor area/building footprint/building
area.
D. The excavation, rehabilitation or in-place reconstruction of existing
vehicular use areas if such work involves the full depth pavement
removal of:
(1)
25% or more of a vehicular use area of over 10,000 square feet;
(2)
50% or more of a vehicular use area of no greater than 10,000
square feet.
3. Interior Landscaping Area Standards. The following landscaping requirements
are intended to promote shading and healthy, vigorous growth of larger
shade trees, shrubs, and ground covers, as well as to create generous
physical space to accommodate rain gardens or depressed absorbent
areas for stormwater infiltration and detention within the parking
lot. The internal parking lot landscaping shall be provided according
to the following standards:
A. Minimum Interior Landscaping area Requirements. The minimum required
interior landscaping area of parking areas shall be a percentage of
the total vehicle use area (VUA) on a lot, as indicated in the requirements
of Figure 6 below. By way of example only, and not limitation, a proposed
VUA of 20,000 square feet requires a minimum interior landscaping
area equivalent to 8% of the VUA, which is 1,600 square feet.
B. Interior landscaping areas shall be composed of planting islands
and planting strips, with planting areas within them. The sum of the
surface areas which are pervious and composed of planting soil with
the required depth and composition as required in this chapter shall
constitute the interior landscaping area.
C. The minimum ground coverage and canopy coverage of planting material,
as determined by the design canopy/ground coverage of the plant species
proposed, shall by 85% of the designated interior landscaping area.
D. The applicant shall provide the number and locations of planting
areas, planting islands and planting strips, to satisfy the requirements
of this section.
E. The applicant shall also propose the number and species of plant
materials to satisfy the requirements of this section above, provided
that a minimum of one shade or canopy tree is provided in a planting
island or planting strip for each 300 square feet of interior landscape
areas provided or fraction thereof. Such shade or canopy trees shall
be distributed throughout the parking lot to ensure well-distributed
canopy coverage of the vehicular use areas.

(d)
Where tree stumps are located within 100 feet of the TPZ, the
stumps shall be removed by means of a stump grinder to minimize the
effect on surrounding root systems.
(e)
Tree roots, which must be severed, shall be cut by a backhoe
or similar equipment aligned radially to the tree. This method reduces
the lateral movement of the roots during excavation, which could damage
the intertwined roots of adjacent trees if done by other methods.
(f)
Within four hours of any severance of the roots, all tree roots
that have been exposed and/or damaged shall be trimmed cleanly and
covered temporarily with moist peat moss, moist burlap or other moist
biodegradable material to keep the roots from drying out until permanent
cover is installed.
(g)
Sediment, retention and detention basins shall not discharge
into a TPZ.
(h)
Sediment, retention and detention basins shall not be located
within a TPZ.
(2)
The Tree Protection Zone (TPZ). Prior to construction or alteration
of the site, the TPZ shall be delineated by the following methods:
(a)
The TPZs shall conform to the approved development plans. Adjustments
in the field may be approved by the Township Engineer.
(b)
All trees scheduled to remain shall be marked. Where groups
of tree are to remain, only the edge trees need to be marked.
(c)
A forty-eight-inch-high construction fence, of a type as approved
on the development plan, shall be placed in the field along the boundary
of the TPZ. The location of the TPZ shall be inspected and approved
by the Township Engineer prior to commencing of clearing or site alterations.
The TPZ fencing shall remain in place and shall be maintained until
all work and construction has been completed. Any protective fencing
that is damage shall be replaced or repaired before further construction
begins.
(d)
Tree to be removed shall not be felled, pushed or pulled into
a TPZ or into trees that are to remain.
(3)
Retaining Walls. Where the original grade cannot be retained
at the TPZ line, a retaining wall shall be constructed outside the
TPZ. The retaining wall shall be designed to comply with standards
recommended by the Township Engineer for retaining walls. In addition,
the following methods shall be used to ensure survival of the trees:
(a)
The top of the wall shall be four inches above the finished
grade line.
(b)
The wall shall be constructed of large stones, brick, building
tiles, concrete blocks or treated wood beams not less than six inches
in width. A means for drainage through the wall shall be provided
so that water will not accumulate on either side of the wall.
(c)
Any severed roots which result from excavation shall be trimmed
so that their edges are smooth and are cut back to the lateral root,
if exposed.
(d)
A layer of clean stone (sized 3/4 to one inch) shall be placed
one foot from the inner side of the wall to aid in drainage.
(4)
Trenching and Tunneling. If there is no alternative to locate
a utility line through a TPZ, tunneling shall be used instead of trenching,
except where, in the opinion of the Township Engineer or a municipal/consultant
arborist, survival of the tree would not be affected by either method.
The Township Engineer or municipal/consultant arborist shall determine
the most appropriate location for the utility line. Trenches shall
be filled as soon as possible and tamped to avoid air spaces.

*
|
If the flood fringe area has been delineated, or if the applicant delineates the floodway and flood fringe area then only the permitted uses stated in § 22-833, Subsection 3E, will be approved by the Township. The applicant must demonstrate to the Township the maximum percentage of area to be affected by the permitted use. If there are other resource protection areas within the flood-fringe area, such as wetland, woodlands, etc., these areas may govern and control use of the flood fringe area where a greater protection standard would apply to the other natural resource. The permitted use may not be allowed if the other resource protection areas restrict the uses. If the flood fringe is delineated by the applicant per § 22-833, Subsection 3E(2), review and approval by the Township and FEMA, as well as the filing of a map revision, will be required as part of the approval of the permitted use.

by Ord. 17-03, 3/27/2017; and by Ord. No. 22-05, 5/5/2022]
1. No structure or land shall hereafter be used and no structure shall be located, relocated, constructed, reconstructed, enlarged, substantially improved or structurally altered except in full compliance with the terms and provisions of this part and any other applicable ordinances and regulations which apply to uses within the jurisdiction of this chapter and all other applicable codes and ordinances such as this chapter and Chapter
5, Code Enforcement, Part
2, Uniform Construction Code. Zoning and building permits shall be required before any construction or development is undertaken within any area of the Township. In addition, all such uses, activities and development shall be undertaken only in compliance with federal or state law, including § 404 of the Federal Water Pollution Control Act, Amendments of 1972, 33 U.S.C. § 1334.
2. Under no circumstances shall any use, activity and/or development
adversely affect the capacity of the channels or floodways of any
watercourse, drainage ditch or any other drainage facility or system.
3. Prior to any proposed alteration or relocation of any stream, watercourse,
etc., within the Township, the proposed alteration shall be evaluated
and receive a conditional approval from FEMA for the work to proceed.
Additionally, a permit shall be obtained from the Department of Environmental
Protection, Bureau of Dams and Waterway Management. Further, notification
of the proposal shall be given to all affected adjacent municipalities.
Copies of such notifications shall be forwarded to both the Federal
Emergency Management Agency and the Department of Community and Economic
Development.
A. Purpose. The purpose of these provisions is to prevent the loss of
property and life, the creation of health and safety hazards, the
disruption of commerce and governmental services, the extraordinary
and unnecessary expenditure of public funds for flood protection and
relief; and to protect the tax base by:
(1)
Regulating uses, activities and development which (acting alone
or in combination with other existing or future uses, activities and
development) will cause unacceptable increases in flood heights, velocities
and frequencies.
(2)
Restricting or prohibiting certain uses, activities and development
from locating within areas subject to flooding.
(3)
Requiring all those uses, activities and development as defined by §
27-202 of Chapter
27, Zoning, that do occur in flood-prone areas to be protected and/or flood-proofed against flooding and flood damage.
(4)
Protecting individuals from buying lands and structures which
are unsuited for intended purposes because of flood hazards.
B. Warning and Disclaimer of Liability.
(1)
The degree of flood protection sought by the provisions of this
chapter is considered reasonable for regulatory purposes and is based
on acceptable engineering methods of study. Larger floods may occur
on rare occasions. Flood heights may be increased by man-made or natural
causes. This chapter does not imply that areas outside the floodplain
districts or that land uses permitted within such districts will be
free from flooding or flood damages.
(2)
This chapter shall not create liability on the part of the Township
or any officer or employee thereof for any flood damages that result
from reliance on this chapter or any administrative decision lawfully
made thereunder.
C. Establishment of Floodplain Areas. For the purpose of this chapter,
various floodplain areas are identified which are subject to the provisions
of this section. These floodplain areas are:
(1)
Floodway, as defined in Part
2 of this chapter.
(2)
Flood fringe, as defined in Part
2 of this chapter.
(3)
Approximate 100-year flood boundary, as defined in Part
2 of this chapter.
(4)
Floodplain soils, as defined in Part
2 of this chapter.
D. Use of Floodplain Areas.
(1)
The floodplain areas described above shall be overlays to the
existing underlying zoning districts and the floodplain provisions
shall serve to supplement the underlying zoning provisions. Where
there is a conflict between the provisions or requirements of any
floodplain requirement and those of the underlying zoning, the more
restrictive provisions and/or those pertaining to the floodplain area
shall apply. However, in all cases the floodplain requirements shall
be met.
(2)
In the event any provision concerning a floodplain regulation
is declared inapplicable as a result of any legislative or administrative
actions or judicial discretion, the basic underlying zoning district
provision shall remain applicable.
(3)
The delineation of any of the floodplain area may be revised
by the Township where natural or man-made changes have occurred and/or
where more detailed studies conducted or undertaken by the U.S. Army
Corps of Engineers, a river basin commission or other qualified agency
or individual documents the notification for such change. Where a
map revision is proposed as part of a subdivision or land development
plan, a conditional letter of map revision must be obtained from the
Federal Management Agency (FEMA) prior to the plan being granted preliminary
approval by the Township.
(4)
Initial interpretation of the boundaries of the floodplain areas
shall be made by the Zoning Officer. Should a dispute arise concerning
the boundaries of any of the areas, the Zoning Hearing Board shall
make the necessary determination. The persons questioning or contesting
the location of the boundary shall be given a reasonable opportunity
to present their case to the Board and to submit their own technical
evidence if they so desire.

Any new manufactured home on a single building lot or replacing an existing unit within an existing manufactured/mobile home park shall be elevated as required and anchored to a permanent foundation. The foundation shall be approved by the Township and it shall be demonstrated that the foundation/unit will be able to withstand all forces of wind and flood.
I. Existing Structures in the Floodplain Areas. A structure or use of
a structure or premises which lawfully existed before November 20,
1969, but which is not in conformity with these provisions, may be
continued subject to the following conditions:
(1)
Existing structures and/or uses shall not be expanded or enlarged
unless the effect of the proposed expansion or enlargement on flood
heights is fully offset by accompanying improvements.
(2)
The modification, alteration, repair, reconstruction, rehabilitation,
addition or improvement of any kind to a structure and/or use, regardless
of its location in a floodplain area, to an extent or amount of 50%
or more of its market value before the start of construction shall
be undertaken only in full compliance with the provisions of this
and any other applicable ordinances.
J. Anchoring, Elevation and Floodproofing Requirements.
(1)
Residential Structures. Within any floodplain area, the lowest
floor (including basement) of any new construction or substantially
improved residential structure shall be at least 1 1/2 feet above
the 100-year flood elevation. The appropriate elevation certifications
shall be submitted to the Township.
(2)
Nonresidential Structures. Within any floodplain area, the lowest
floor (including basement) of any new construction or substantially
improved nonresidential structure shall be at least 1 1/2 feet
above the 100-year flood elevation, or be designed and constructed
so that the space enclosed by such structure shall remain either completely
or essentially dry in accordance with the publication entitled "Flood-Proofing
Regulations" (U.S. Army Corps of Engineers, June 1972), or some other
equivalent standard, for that type of construction. All plans and
specifications for such floodproofing shall be accomplished by a statement
certified by a registered professional engineer or architect which
states that the proposed design and methods of construction are in
conformance with the above referenced standards.
(3)
Anchoring.
(a)
All buildings and structures shall be firmly anchored in accordance
with accepted engineering practices to prevent flotation, collapse
or lateral movement.
(b)
All air ducts, large pipes, storage tanks and other similar
objects or components located below the regulatory flood elevation
shall be securely anchored or affixed to prevent flotation.

D. Open space shall have the physical characteristics capable of serving
the purposes intended for such areas including recreational use.
E. Open space shall be visible from dwelling units and roadways.
F. Open space shall protect environmentally sensitive and/or aesthetic
features and be landscaped to provide sufficient screening or buffer
areas to minimize any negative impacts from or upon adjacent development.
5. Open Space Designation. All land held for open space shall be so
designated on the plans. The plans shall contain the following statement
for land categories in Subsection 2A, B, C or D below: "Open space
land may not be separately sold, nor shall such land be further developed
or subdivided." All plans shall further designate the use of open
space, the type of maintenance to be provided and a planting plan
or schedule. In designating use and maintenance, the following classes
may be used:
A. Lawn. A grass area with or without trees which may be used by the
residents for a variety of purposes and which shall be mowed regularly
to insure a neat and orderly appearance.
B. Natural Area. An area of natural vegetation undisturbed during construction,
or replanted. Such areas may contain pathways. Meadows shall be maintained
as such and not left to become infested with invasive species. Maintenance
may be minimal, but shall prevent the proliferation of weeds and other
invasive plants such as honeysuckle and poison ivy. Litter shall be
removed and streams shall be kept in free-flowing condition.

8. Ownership of Open Space. Any of the following methods may be used
to preserve, own or maintain open space. However, the open space shall
be initially offered for dedication to the Township:
A. Condominium. The open space may be controlled through the use of
condominium agreements. Such agreements shall be in conformance with
the Pennsylvania Uniform Condominium Act, 68 Pa.C.S.A. § 3101
et seq. All open space land shall be held as "common element." Such
land shall not be eligible for sale to another party except for transfer
to another method of ownership permitted under this section, and then
only where there is no change in the open space ratio.
B. Homeowners' Association. The open space may be held in common ownership
by a homeowners' association. This method shall be subject to all
of the provisions for homeowners associations set forth in Article
VII of the Pennsylvania Municipalities Planning Code, 53 P.S. § 10701
et seq.
C. Fee-Simple Dedication. The Township may, but shall not be required to, accept any portion or portions of the open space provided: (1) such land shall be freely accessible to the public; (2) there shall be no cost to the Township involved; (3) the Township agrees to and has access to maintain such lands; and (4) the open space shall be in an acceptable condition to the Township at the time of transfer with regard to size, shape, location and improvement. Refer to Subsection
4E below for additional requirements.
D. Dedication of Easements. The Township or county may accept, but shall
not be required to accept, easements to any portion or portions of
the open space. In such cases, the land remains in the ownership of
the individual, condominium or homeowners' association while the easements
are held in public ownership. The county shall accept the easements
only in accordance with the provisions of Act 442, 32 P.S. § 5001
et seq., and county plans. The Township may accept such easements
as it sees fit. In either case, there shall be no cost to the county
or Township for acquisition or maintenance. The Township may require
this method where it seems this is the most appropriate way of preserving
land in open space. In performance standard developments and mobile
home parks, this provision for the ownership and preservation of open
space cannot be used except for open space land incorporated in required
buffer yards.
E. Transfer to a Private Conservation Organization. With permission
of the Township, an owner may transfer either the fee simple title,
with appropriate deed restrictions running in favor of the Township,
or easements, to a private, nonprofit organization, among whose purposes
is to conserve open space land and/or natural resources; provided
that: (1) the organization is acceptable to the Township and is a
bona fide conservation organization with perpetual existence; (2)
the conveyance contains appropriate provision for proper reverter
or retransfer in the event that the organization becomes unwilling
or unable to continue carrying out its functions; and (3) a maintenance
agreement acceptable to the Township is entered into by the developer
and the organization.
F. Deed Restrictions.
(1)
Natural resource protection open space, as required by this
chapter, may be held in the ownership of the individual property owners
of residential developments. This form of ownership of open space
will be subject to the following requirements:
(a)
This form of ownership will be limited to residential uses that
do not require common open space.
(b)
It may be used only if approved by the Township.
(c)
Restrictions meeting Township specifications must be placed
in the deed for each property that has natural resource protection
areas within its boundaries. The restrictions shall provide for the
continuance of the resource protection areas in accordance with the
provisions of this chapter.
(d)
It will be clearly stated in the individual deed that the maintenance
responsibility lies with the individual property owner.
(2)
For nonresidential uses, buffer yards and areas of natural resource
features may be held with the ownership of the entire parcel provided
the buffer yards and natural features are deed restricted to ensure
their protection and continuance.
(3)
In the case of residential developments where all of the units
are rental, the open space land may be in the same ownership as that
of the development, provided that the land is deed restricted to ensure
its protection and continuance and that a maintenance agreement suitable
to the Township is provided.
(4)
For any of these options the Township may accept, but is not
required to accept, an easement to the open space land in the development.
9. Costs. Unless otherwise agreed to by the Township or county, the
cost and responsibility of maintaining open space shall be borne by
the property owner, condominium association or homeowners' association.
If the open space is not properly maintained, the Township may assume
responsibility of maintenance and charge the property owner, condominium
association or homeowners' association a fee which covers maintenance
costs, administrative costs and penalties as stipulated in this chapter.

C. An on-site investigation by the applicant shall determine the adjacent
land uses along each property boundary. In the case of vacant land,
the uses permitted by the existing zoning shall be used to determine
the screen type. If more than one type of use is permitted on a site,
the use that would require the highest intensity site element screen
shall be used to determine the screen type. The existing or zoned
uses shall be noted on the plan.
D. Site elements not included in the above list that have similar visual
impact shall be screened in accordance with requirements for the most
similar elements as determined by the Board of Supervisors.
E. Screen Location. The site element screen shall be placed between
the site element and property lines, existing or proposed public streets
and common use areas within a site and shall be designed to block
views to the maximum extent possible. The screen shall be located
as close as possible to the site element and shall surround the element
without impeding function or encroaching on sight triangles.

to accept in dedication land for recreational purposes and/or open
space purposes, such acceptance shall be by adoption of a resolution
or ordinance of the Board of Supervisors and acceptance of a deed
of dedication from the developer, and in addition thereto the developer
shall contribute to the Township a sum of money to be determined by
resolution of the Board of Supervisors. Said sum shall be deposited
in a special maintenance account by the Township and shall be used
only for the purpose of developing and maintaining dedicated land
within the Township. In addition, where the Board of Supervisors has
deemed it to be in the public interest to accept in dedication land
for recreational purposes and open space purposes, the developer shall
contribute to the Township a sum of money to be determined by resolution
of the Board of Supervisors. Said sum shall be deposited in a special
capital reserve account by the Township and shall be used only for
the purpose of acquisition of land or capital improvements for park
and recreation purposes.
N. Such recreation area shall not be part of any lot, but it shall be
dedicated to the Township in fee simple title or, in the sole discretion
of the Board of Supervisors, to the extent that the same is intended
to be developed as part of the trail and bikeway system of the Township,
it shall be dedicated to the Township as a right-of-way or easement
to be perpetually maintained for the purposes intended with full access
and used by the general public constituting the residents, constituents
and the invitees of the Township, the documentation for which shall
be submitted to and subject to the approval of the Board of Supervisors
of New Hanover Township and its Solicitor and in the case of a right-of-way
or easement for public use and access, the plan shall provide that

Q. The amount and location of land to be dedicated or the fees to be
paid shall bear a reasonable relationship to the use of the park and
recreation facilities by future residents, occupants, employees or
visitors to the subdivision or land development.
4. Standards for Fee in Lieu of Land Dedication.
A. Subject to the discretion of the Board of Supervisors, payment of
a fee in lieu of land dedication shall be required:
(1)
Where land dedication would result in open space or recreation
areas too small to be usable.
(2)
If the Township Comprehensive Plan or the Township Open Space,
Parks and Recreation Plan recommends recreation land to be provided
elsewhere.
(3)
If a suitable site for recreation cannot be located within the
development.

facilities, vehicular and pedestrian access, signage and the purchase
of park equipment and maintenance.
D. All fees paid to the Township shall be deposited in a separate interest-bearing
account established for such fees, the records for which shall clearly
identify the specific subdivision/land development sites for which
such fees have been received; interest earned on such fees shall become
funds of that account and be subject to distribution or expenditure
for any and all costs and expenses hereinbefore identified. Funds
from such accounts shall be expended only in properly allocable portions
of the costs incurred to acquire, construct or improve such specific,
identifiable, and/or proposed recreation facilities for which such
funds have or may hereafter be collected.
E. If the Township fails to use the fees collected from a particular
applicant in accordance with this section within three years of the
date such fees were paid, the specific applicant may submit a written
request, on such forms as are established by the Township, for the
refund of such fees, plus interest that accumulated thereon from the
date of fee payment, which request shall be reviewed and acted upon
by the Board of Supervisors of New Hanover Township with 45 days of
the date of receipt.
5. Combination of Land Dedication and Fees in Lieu of Land Dedication.
A. The Township may accept a combination of land dedication in fee simple
title, grants of rights-of-way and easements and fees in lieu of land
in order to meet the requirements and standards of the New Hanover
Township Open Space Park and Recreation Plan or such additional plans
and designs as may be approved for the Township trail and bikeway
system. Such combination shall be subject to the review and approval
of the Board of Supervisors of New Hanover Township at its sole discretion.
B. The resulting combination of land and fees shall not, except as may
be otherwise reduced to recognized rights-of-way granted for the trail
and bikeway system, exceed the total acreage to be developed or the
acreage which constitutes the basis of calculating the fee in lieu
of dedication required by this part.
6. Decision of Land Dedication vs. Fees in Lieu of Land Dedication.
A. Before approving any site to be dedicated to the Township for recreational
area and open space, the Board of Supervisors shall seek the advice
of the Township Parks and Recreation Committee and the Township Planning
Commission.
B. The Board of Supervisors shall determine whether land dedication,
grant of rights-of-way and easements or fees in lieu of land shall
be required. Such decision shall be made as early in the plan review
process as possible but not later than concurrent with the preliminary
plan approval.
C. The Board of Supervisors shall, in reaching its decision, consider
the following factors, in addition to any other factors that may be
applicable to a particular plan:

If the land in that location serves a valid public purpose.
(2)
If there is a need to make a reasonable addition to an existing
park or recreation area.
(3)
If the land meets the objectives and requirements of this section.
(4)
If the area surrounding the proposed development has sufficient
existing parks, recreation areas or facilities or open space and if
pedestrians or bicyclists can safely reach these areas.
(5)
Any relevant policies of the Township regarding parks, recreation
areas and facilities and open space, including those within the Township
Comprehensive Plan and the Township Open Space, Park and Recreation
Plan.
(6)
Any recommendations regarding such land that has been received
from the Township and/or County Planning Commission, the Township
Parks and Recreation Board, the Township Engineer and/or the Boyertown

and by Ord. No. 22-05, 5/5/2022]
1. Bicycle Facility Definitions.
BICYCLE FACILITY
A general term used to designate all bicycle infrastructure
along roadways. Examples of bicycle facilities are shown below.
BICYCLE LANES (STANDARD)
Standard bicycle lanes are a form of bicycle facility that
are adjacent to vehicular travel lanes and marked specifically for
bicycle use.
BUFFERED BICYCLE LANES
Bicycle facilities that use a painted buffer to increase
separation between bicyclists and motor vehicles. Buffers can be installed
on either side of the bike lane to separate it from the travel and
parking areas. Crosshatching is often used to delineate the buffer
area.
MARKED SHARED LANES
Marked shared lanes are bicycle facilities that include pavement
markings and signage that reinforce the right of bicyclists to use
the roadway and to remind drivers of the presence of bicyclists. Also
known as "sharrows."
PAVED SHOULDER
Bicycle facility where areas of the roadway that are outside
of the primary travel lane. They are often delineated by a painted
line along the outer edge of the travel lane. These areas are not
only designated for bicycles and may be used for parking.
PROTECTED BICYCLE LANES
Bicycle facilities with bicycle lanes that are separated
from the roadway by physical barriers. These barriers can be flexible
plastic posts, inanimate objects, curbs, parking lanes, or raised
bumps made out of rubber or impact-resistant plastic.
WIDE OUTSIDE LANE
Wide outside lanes are bicycle facilities that are at least
14 feet wide and allow motor vehicles and bicycles to operate side
by side.
2. Bicycle Facility Application.
A. This section provides input on when each bicycle facility may be
utilized based on general roadway type and projected traffic volumes.
All bicycle facilities shall comply with the American Association
of State Highway and Transportation Officials (AASHTO) Guide for the
Development of Bicycle Facilities Fourth Edition, as amended as well
as PennDOT standards.
(1)
The following table shall be used to determine which bicycle
facilities are suitable for specific road classifications. If a bicycle
facility has already been established on adjacent properties, then
the Board of Supervisors may require a different bicycle facility
to maintain consistency along the roadway.

The Board of Supervisors may allow these bicycle facilities
if the other facilities are not feasible or suitable for the specific
site.
|
(2)
Protected bicycle lanes are best used on wider roads with high
traffic volumes.
(3)
Buffered bicycle lanes are suited for wider streets with higher
traffic volumes and should be installed in areas where a five-foot
conventional bicycle lane cannot be established.
(4)
Standard bicycle lanes shall be at least six feet wide and are
best suited for wider streets with higher traffic volumes.
(5)
Paved shoulders shall be a minimum of five feet wide. When used
along arterial roads, paved shoulders shall be a minimum of six feet
wide. Paved shoulders are best suited for rural roadways where regular
restriping of a bicycle lane may be cost prohibitive or where intermittent
parking is expected.
(6)
Marked shared lanes are best used on narrower roads with slower
speed limits and lower traffic volumes where additional facilities
cannot be installed due to space constraints.
(7)
Wide outside lanes are best used on collector and arterial roads
with higher traffic volumes where adequate width for the installation
of a full bicycle lane is not available. They should only be relied
upon for short distances as they will not provide significant bicycling
comfort.
(8)
The provision of shared-use paths, compliant with §
22-828, is encouraged.
B. When a subdivision or land development includes improvements to streets
which have been specified on Bike Montco: The Bicycle Plan for Montgomery
County or Township-adopted plans or maps to receive future bicycle
infrastructure improvements, bicycle routes or lanes shall be created
according to the road, speed and applicant's frontage as indicated
in the aforementioned plans.
3. Bicycle Facility Requirements.
A. All subdivisions and land developments that front on or contain collector
roads or roads of a higher classification shall be required to establish
bicycle facilities along those roads. In lieu of establishing bicycle
facilities, as described herein, subject to the discretion of the
Board of Supervisors, a fee may be paid by the applicant in a subdivision
or land development proposal according to the following schedule:
(1)
For a subdivision or land development involving residential
lots or dwelling units, $1,200 per residential lot or dwelling unit,
or $18 per linear foot of existing and proposed roadway frontage,
whichever sum is greater.
(2)
For a subdivision or land development involving nonresidential
lots, $1,200 for every 1,000 square feet of nonresidential building
area.
(3)
All fees paid in lieu of bicycle facilities shall be used on
or for:
(a)
The acquisition of land for bicycle facilities, multipurpose
paths, or greenway trails, as component additions to the New Hanover
Township system of parks, trails, greenways and open space as shown
on the New Hanover Township Open Space Plan and subsequent updates.
(b)
The construction of improvements on such land.
(c)
Costs incidental to such purposes including, but not limited
to, planning, engineering, design, administrative and legal fees,
access, signage, equipment and maintenance.
(4)
All fees paid to the Township shall be deposited in a separate
interest-bearing account established for such fees, the records for
which shall clearly identify the specific subdivision/land development
sites for which such fees have been received. Interest earned on such
fees shall become funds of that account and be subject to distribution
or expenditure for any and all costs and expenses hereinbefore identified.
Funds from such accounts shall be expended only in properly allocable
portions of the costs incurred to acquire, construct or improve such
specific, identifiable and/or proposed bicycle facilities, shared-use
path or greenway trail for which such funds have or may hereafter
be collected.
(5)
If the Township fails to use the fees collected from a particular
applicant in accordance with this section within three years of the
date such fees were paid, the specific applicant may submit a written
request, on such forms as are established by the Township, for the
refund of such fees, plus interest that accumulated thereon from the
date of fee payment, which request shall be reviewed and acted upon
by the Board of Supervisors of New Hanover Township within 45 days
of the date of receipt.
B. Construction Standards. All on-road bicycle facilities shall meet the design requirements of the road. All off-street shared-use paths shall meet the design requirements from §
22-828 for shared-use paths.
C. Bicycle Facility Fencing. All shared-use paths and bicycle facilities
shall provide the following style of fencing along the length of the
proposed trail, where specified by the Township. (The shared-use path
and bicycle facility trail fence detail is attached hereto incorporated
herein, marked as Exhibit "A.")
D. Signs and Markings. All signs and markings required pursuant to the
terms of this chapter shall conform to the standards set in the latest
edition of the Manual on Uniform Traffic Control, or subsequent amendments,
and PennDOT regulations.
