The following land subdivision and development
principles, standards and requirements shall be applied by the Township
Engineer, Planning Commission and Board in evaluating plans for proposed
subdivisions and land developments. These principles, standards and
requirements are the minimum provisions required by the Township for
the promotion of public health, safety, and general welfare.
A.
Land utilization and zoning. All proposed subdivisions and land developments shall comply fully with the applicable provisions of Chapter 200, Zoning, of the Code of the Township of East Whiteland. The lands proposed for subdivision and/or land development shall be suited for the purposes for which they are to be subdivided or developed by adherence to the specific standards and criteria set forth in this Article VI, and no parcel of land shall be created, either by inclusion or exclusion from a proposed subdivision or land development, which cannot be properly utilized consistently with the requirements of this chapter and the regulations of other governmental agencies having jurisdiction over any aspect of the proposed development for a permitted use under the existing zoning regulations.
B.
Restricted land. Land subject to hazards to life,
health or property, such as may arise from fire, floods, wetlands
conditions, disease, exposure to toxic or noxious fumes, wastes or
substances or other cause shall not be subdivided for building purposes
or developed unless the hazards have been eliminated or unless the
plans show adequate safeguard against them consistently with the requirements
of Township, state and federal ordinances, statutes, laws and regulations.
C.
Coordinated development. Proposed subdivisions and
land developments shall be coordinated with existing nearby neighborhoods
and communities, with particular reference to street layout and interconnection,
except where precluded by other governmental regulation or direction
of the Board, and the provisions of sanitary sewage and water facilities
and the adequacy and availability of those services and facilities
so that the community and region as a whole may develop harmoniously.
D.
Design specifications and standards. The design of all improvements in a subdivision or land development shall be in accordance with the design specifications, standards and requirements as set forth in this Article VI and other provisions of this chapter and/or other applicable ordinances, or, in the absence of the foregoing, in accordance with applicable provisions of the latest design specifications, standards, and requirements of the PADOT, PADEP and/or such other governmental agency or body which promulgates or otherwise issues design standards, specifications, and requirements relevant to the work. In the event that this chapter does not provide for a specific design specification, standard or requirement relevant to any design or improvement aspect of a proposed subdivision or land development, accepted engineer design specifications or standards in Chester County shall govern such improvement and such design specification or standard shall be subject to the reasonable approval of the Township Engineer.
E.
Preclusion of remnants and landlocked areas. All portions
of a tract being subdivided shall be utilized in lots, streets, public
lands or other proposed uses so that remnants and landlocked areas
shall not be created.
F.
Plan requirement for partial subdivision. When only
a portion of a tract or single holding is the subject of a subdivision
or land development application, a sketch layout shall be included
for the balance of the tract.
G.
Community asset preservation. Developer shall preserve trees, groves, waterways, scenic points, historic spots and other community assets and landmarks consistently with the requirements of this Article VI.
H.
Cuts and fills. Subdivisions and land developments
shall be laid out so as to avoid the necessity for excessive cut or
fill unless specifically warranted by terrain or location. No cut
or fill, with the exception of the area of a basement or a cut and
fill on an individual lot necessary to allow the construction of a
house thereon shall exceed five feet unless a waiver is granted by
the Board upon due cause shown.
I.
Floodplain regulation. Floodplain and flood hazard areas shall not be developed except in strict compliance with the Flood Hazard District regulations of Chapter 200, Zoning, of the Code of the Township of East Whiteland.
J.
Water and sewer facilities.
(1)
Where either water supply or sanitary sewage disposal
is proposed to be provided by on-lot facilities, all applicable Township,
Chester County and PADEP standards and those of other agencies having
jurisdiction must be fully satisfied and either the Chester County
Department of Health or PADEP, whichever has jurisdiction, must issue
a permit authorizing and approving the design and installation of
these facilities. All sewage facilities shall be in compliance with
the Township's Act 537 plan, including approved revisions thereto.[1]
[1]
Editor's Note: "Act 537" refers to the Pennsylvania
Sewage Facilities Act; see 35 P.S. § 750.1 et seq.
(2)
Where no public water system is available to serve
the proposed subdivision or land development prior to final plan approval,
the Board shall require the developer to obtain from the governmental
authority have jurisdiction (either PADEP or Chester County Department
of Health) certifications of approval as to the quantity and adequacy
of the water supply proposed to be utilized by the developer and approval
of the type and construction methods and materials to be employed
by the developer in the installation of the community on-lot disposal
system. If a Pennsylvania Public Utility Commission franchise approval
is required, evidence of such approval shall be required prior to
final plan approval or, in the alternative, if the developer demonstrates
such approval cannot be secured by that time, then such approval shall
be a condition of final plan approval and no building permits shall
be issued until proof of the approval is filed with the Township.
K.
Improvement specifications. Where not otherwise provided
for or specified in this chapter, construction requirements for any
improvements other than buildings shall be as specified under PADOT's
Publication 408, the rules and regulations of PADEP, the Chester County
Conservation District, or other governmental agencies, as applicable.
Where the specifications included in this chapter differ from the
foregoing, the more stringent specification shall apply unless waived
by the Board upon recommendation of the Township Engineer.
L.
Installation and inspection of improvements. The developer
shall construct and install at his expense all streets, curbs, sidewalks,
water mains, sanitary and storm sewers, streetlights, fire hydrants,
street signs, shade trees, monuments and other required improvements,
facilities and utilities specified in or required by this chapter.
Construction and installation of all such improvements shall be subject
to inspection by and approval of the Township Engineer and/or Codes
Enforcement Officials periodically during the progress of the work.
M.
Lots. In all proposed subdivisions or land developments each lot shall have the specified lot width at the street line and otherwise comply with all applicable requirements of Chapter 200, Zoning, of the Code of the Township of East Whiteland and shall abut a street, either existing or proposed as a part of the subdivision or land development which meets Township street specifications contained in this chapter.
N.
Stormwater retention. In order to minimize the flood-enhancing
potential resulting from land disturbance and impervious cover associated
with the subdivision or development of land and to maximize the recharge
of groundwater, wherever reasonably required by the Board based upon
objective criteria incident to the condition of the land proposed
for development, stormwater shall be retained on site and ultimately
percolated into the ground rather than permitted to drain off.
O.
Municipal exemption. To the extent feasible, the Township
shall adhere to the requirements of this chapter; provided, however,
that the Supervisors shall have the discretion at a public meeting
of the Supervisors to waive any one or more of the provisions of this
chapter as they apply to any building or lands owned by the Township
or extension thereof, or to the use of any premises owned or operated
by the Township that they deem appropriate in the public interest
without the necessity of complying with or requiring adherence to
the standards required by PAMPC Section 512.1.[2]
[2]
Editor's Note: See 53 P.S. § 10512.1.
A.
Location, A proposed street shall not be centered
upon a boundary line of a tract to be subdivided or developed unless
the owner of the adjoining property shall enter into joint or simultaneous
application for the subdivision or land development of his land. Location
of a proposed street abutting and parallel to a boundary line of a
development tract is prohibited.
B.
Interconnection of streets. Residential or local streets shall be laid out so as to discourage through traffic, but provisions for street connections into and from adjacent areas may be required by the Board where circulation patterns warrant such connection. No connection shall be permitted which does not comply with any of the objective standards and criteria relating to streets in this Article VI or when a traffic study demonstrates that such interconnection will create a hazardous condition.
C.
Alignment relative to surrounding residential streets.
Where a proposed subdivision or land development abuts an existing
subdivision having a dedicated residential street dead-ending or terminated
by a cul-de-sac at or near a common property line, the proposed subdivision
or land development shall make provision for extension of such dedicated
residential street within the proposed subdivision or land development.
D.
Alignment relative to surrounding collector streets.
A proposed subdivision or land development shall make provision by
means of a collector street for continuation of the width, gradient,
general alignment and direction of traffic flow of an existing collector
street which dead-ends or terminates in a cul-de-sac at a common property
line.
E.
Relationship to the development site. Streets shall be designed and laid out in relation to the undisturbed topography of the development tract so as to reduce land disturbance, optimize safe and adequate access to each lot, avoid disturbance of slopes exceeding 15%, and to provide adequate sight distance at all points of intersecting streets as required by §§ 175-32 and 175-33 of this Article VI.
F.
Future streets. If lots resulting from original subdivision
or land development are of sufficient size to permit resubdivision
or further development, or when a portion of the development tract
is not currently proposed for subdivision or land development, adequate
street rights-of-way allowing for future subdivision or land development
shall be incorporated as part of the plan design and shall satisfy
the minimum rights-of-way required for major, collector, minor, or
single access streets, as applicable.
G.
Traffic control and street signs. The developer shall provide standard PADOT approved traffic control signs for all streets within a subdivision or land development. The proposed street signs shall be provided in accordance with § 175-33 and the locations of such signs shall be shown on the final plan.
H.
Relationship to existing or proposed collector streets.
Where a subdivision or land development abuts or contains an existing
or proposed collector or arterial street, the Board, to the extent
permitted by law, may require dedication of additional right-of-way
to meet the minimum right-of-way specified hereinafter. Additional
right-of-way shall be required whenever the developer is required
to install acceleration or deceleration lanes or similar improvements
required to serve the development.
I.
Grid-iron street pattern. A rigid "grid-iron" pattern
of straight, parallel streets which disregards topography is prohibited
in those instances where variation in alignment or sweeping curves
with tangents is more compatible with topography. Tangents which are
up to three times the length of connecting curves shall be required
unless determined inappropriate by the Township Engineer based on
the undisturbed condition of the development tract.
J.
Relationship to Township street plan. Proposed streets
shall be properly related to such street plans or,parts thereof as
have been officially prepared and adopted by the Township and to such
county and state road and highway plans as have been prepared, adopted
and/or filed as prescribed by law.
K.
Reverse frontage. Wherever a development abuts or
contains an existing or proposed public street with a right-of-way
of 33 feet or more, restrictions of access to the street by the provision
for reverse-frontage lots shall be required.
L.
Half or partial streets. New half or partial streets
shall not be permitted, except where essential to facilitate the reasonable
subdivision of a tract in conformance with the other requirements
and standards of this chapter and where, in addition, satisfactory
assurance for dedication of the remaining part of the street can be
secured.
M.
Incorporation of adjacent partial streets. Wherever
a tract to be subdivided or developed borders on an existing half
or partial street, the other part of the street shall be shown on
the plan of development as being located within the development tract.
N.
Dead-end streets. Dead-end streets shall be prohibited,
except as stubs to permit future street extension into adjoining tracts
or when such streets are designed as cul-de-sac streets.
O.
Street access to state and Township streets and highways. Where a subdivision or land development abuts a state or Township street or highway to which the subdivision or land development is proposed to be connected by means of a street, the applicant shall be required to apply for a highway occupancy permit and to comply with the applicable provisions of §§ 175-31 through 175-34 of this chapter, and, in addition, shall secure from the Township Engineer a written recommendation of the suitability of such connection in terms of adequacy of access. The applicant shall demonstrate the suitability and adequacy of such access in terms of safety, clear sight distance, traffic volumes on the abutting street or highway, anticipated traffic volumes from the development, direction of turning movements to and from the development site, adequacy of traffic signalization, street alignment, and the need for acceleration and/or deceleration lanes or turning lanes on the existing street or highway. Where such access is proposed to a state street or highway, in addition to the issuance of a highway occupancy permit by PADOT, the applicant shall secure a highway occupancy permit from the Township at the time of final plan approval, the feasibility of which shall be demonstrated upon submission for review of the preliminary plan. Highway occupancy permits authorizing connection to state streets or highways shall be approved subject to the condition that if PADOT denies a highway occupancy permit for the proposed access, the conditional approval of such permit by the Township shall be deemed to have been denied and no such municipal permit shall be issued. If the Township denies a Township highway occupancy permit for the said access, the approval of PADOT highway occupancy permit shall be deemed to have been denied.
[Amended 11-13-2019 by Ord. No. 320]
A.
Single access streets shall not be approved wherever a through street connecting with other surrounding streets is feasible, unless such a connection is impractical or undesirable per the considerations outlined in § 175-29F.
B.
Measurement of length. The length of a single access street shall
be measured along the center line of the street beginning at the center
line of the intersecting street and ending at the center of the cul-de-sac
bulb or the point at which a loop street connects back to itself.
C.
A single access street, permanently designed as such, shall not exceed 1,000 feet in length, unless an emergency access is provided. Any required emergency access or fire apparatus access road shall be constructed in accordance with Chapter 90 of the Township Code (Fire Prevention).
D.
An emergency access may also be required for a single access street that will not exceed 1,000 feet in length, whether permanently designed as such or as part of a phased development, if so required by the International Fire Code. Any required emergency access or fire apparatus access road shall be constructed in accordance with Chapter 90 of the Township Code (Fire Prevention).
E.
Radius. Where permitted, a cul-de-sac shall be provided at the closed
end with a paved turnaround having a minimum radius to the outer pavement
edge or curb line of 50 feet with a minimum right-of-way radius of
60 feet.
F.
Design and connection. The Board shall consider the existing or proposed
uses of adjoining lands, topography, drainage and other relevant site
characteristics affecting the design of a single access street or
through street. Unless a through street or future extension of a single
access street is impractical or undesirable based on the foregoing
considerations, or is precluded by the Board, which they shall have
the discretion to do, the right-of-way of a single access street shall
extend to the property line of the development tract and a right-of-way
for the same width as the street shall be carried to the property
line in such a way as to permit future extension of the street into
the adjoining tract. The future street extension shall be clearly
identified with signage.
G.
Drainage. Drainage of a single access street shall be directed towards the open end of the cul-de-sac or loop end of the street, subject to the other design criteria specified in this chapter. All stormwater management and street drainage shall be in accordance with Chapter 170 of the Township Code (Stormwater Management).
H.
Design. The design of single access streets shall be designed to
local or residential street standards, except that the centerline
grade shall not exceed 8% and the grade of the diameter of the turnaround
area shall not exceed 4%.
I.
Temporary cul-de-sac. Where streets are temporarily terminated at
a property line or phase line with a temporary vehicular turnaround,
thus forming a cul-de-sac until such time as the street is extended,
all regulations pertaining to single access streets shall apply, except
that the temporary cartway turnaround need not be curbed unless so
directed by the Township Engineer. At such a time that the temporary
cul-de-sac has been extended and is no longer needed for the purposes
of a turnaround, the additional pavement from its radius shall be
removed and the ground restored to a vegetation condition.
[Amended 11-13-2019 by Ord. No. 320]
A.
Streets in floodplains. Streets within a subdivision or land development
located entirely or partially within a designated Flood Hazard District

E.
Improving existing streets. Where a subdivision or land development
abuts or contains an existing street with a right-of-way, travel lanes,
shoulders, parking lanes, and/or alignment which are insufficient
relative to the anticipated traffic demands of the development and/or
does not otherwise comply with the provisions of this chapter, the
Board shall require that the street be modified to comply with the
applicable sections of the East Whiteland Township ordinances.
[Amended 11-13-2019 by Ord. No. 320]
A.
Sight distance. The minimum sight distance, measured along an unobstructed
line of sight within the paved area along all sections of the street
surface, with the height of the driver and the object at 3.5 feet
above the pavement surface, shall be provided in accordance with the
American Association of State Highway and Transportation Officials
standards and not less than 200 feet for distributor, local, and residential
streets.
B.
Horizontal curves. Whenever street centerlines are deflected in excess
of 5° for local streets, and one degree for all other streets,
connection shall be made by horizontal curves. Horizontal curves shall
have a minimum centerline radius and superelevation in accordance
with the American Association of State Highway and Transportation
Officials standards and not less than 150 feet for local streets with
a posted speed limit of 25 miles per hour.
C.
Tangents. Tangents with a maximum difference in bearing of 5º
may intersect at the center line of intersections with cross streets;
otherwise, such intersections shall not be permitted. Reverse curves
on local streets, and horizontal curves on all other streets shall
be separated by tangents of not less than 100 feet. Superelevation
shall be provided as required by the American Association of State

of the subdivision or land development, discuss its findings and the
further requirements of this section with the subdivider or land developer
as it deems necessary in the furtherance of the public interest and
the provisions of this section, and make such report thereon as it
deems necessary for consideration by the Board in its review and processing
of the development application.
(2)
Developers shall be required to provide or reserve
areas for facilities normally required in residential neighborhoods,
including open space, parks, playgrounds and play fields. Areas provided
or reserved for such community facilities shall be adequate to provide
for building sites, landscaping and off-street parking as appropriate
to the types of facilities required or likely to develop in the future.
Prior to the preparation of plans, developers shall review with the
Planning Commission and the Park and Recreation Board the minimum
standards for various community facilities applicable to the tract
being subdivided.
B.
Amount of land required to be set aside; fee in lieu
of acreage.
(1)
In residential subdivisions or land developments which
are proposed to contain, or by resubdivision could contain, 10 or
more residential units, the developer shall be required to set aside,
design and develop for park, open space and recreation use (hereinafter
called "POR") of the residents within the development the amount of
land determined by application of the following formula:
Approved Dwelling Units Units Per Acre
|
POR Area For Each 10 Dwelling Units
| |
---|---|---|
Less than 2
|
10,000 square feet
| |
Less than 5
|
12,000 square feet
| |
5 or more
|
16,000 square feet
|
(2)
In residential subdivisions proposed to contain less than 10 dwelling units or in those residential subdivisions where application of the requirements of Subsection A of this § 175-40 are impracticable in terms of the criteria and standards established in Subsection C of this section, the Board's general policy, upon concurrence of the developer, is to require a fee in lieu of the minimum acreage otherwise required by application of Subsection A of this section.
(3)
The Board may require the public dedication of land by the developer for POR, the payment of fees in lieu thereof or the private reservation of land for such purpose, or combination thereof, in accordance with the formally adopted East Whiteland Township Recreation Plan. In such instances, the required recreation areas and facilities shall be in accordance with the principles and standards otherwise provided for in this chapter or in Chapter 200, Zoning, of the Code of the Township of East Whiteland.
(4)
The amount of any fee in lieu of the dedication or
reservation of land and provision of recreational facilities shall
be fixed from time to time by the Board in a resolution designated
for that purpose. All fees so collected shall, upon their receipt
by the Township, be deposited in the Township's Park, Open Space and
Recreation Reserve Fund, which shall be an interest-bearing account.
Such fees shall be expended only for the acquisition of land or recreation
facilities within the Township at such locations as shall be selected
by the Board for the establishment, enlargement or improvement of
community or neighborhood parks and recreational facilities accessible
to the subdivision or land development for which such fees have been
paid.
(5)
Funds from such accounts shall be expended for only
and properly allocable portions of the costs incurred to acquire or
construct the recreational land and facilities for which the fees
were collected. Upon request of the developer who has paid such fees,
the Township shall refund such fees, plus interest accumulated thereon
from the date of payment, if the Township fails to utilize the fees
so paid for such purposes within three years from the date on which
such fees were paid, unless the developer specifically waives, in
writing, the requirement that such fees be expended within such time
or waives, in writing, that such fees be repaid.
C.
Criteria. In designating areas for recreation within
a subdivision or land development, the following criteria and standards
shall be followed by the developer. All land designated for the foregoing
purposes shall be:
(1)
Suitable and usable for both active and passive recreational
uses to the extent deemed necessary by the Planning Commission and
Board, without interfering with adjacent dwelling units, parking,
driveways and roads. Active recreational uses include but are not
necessarily limited to play fields, ball fields, tennis and racquetball
courts, basketball courts, fitness trails, picnic areas, recreational
buildings and similar facilities. The minimum area required for active
recreational open space use, which shall be comprised of ground suitable
for development and construction of such uses thereon, shall not be
less than 50% of the total required recreation located as determined
reasonably necessary by the Planning Commission and Board.
(2)
Comprised of no more than 30% environmentally sensitive
lands, including floodplains, woodlands and surface waters restricted
to passive use.
(3)
Comprised of areas not less than 100 feet in width,
except when part of a trail system or pathway network.
(4)
Interconnected with common recreation areas on abutting
parcels wherever possible, including provisions for pedestrian pathways
for general public use to create a linked pathway system within the
Township. The recreation shall be accessible to all dwelling units
within the development, either by abutting the recreation or over
easements expressly dedicated for that purpose, but must, nevertheless,
be accessible by one or more public streets.
(5)
Provided with sufficient parking when determined reasonably
necessary by the Planning Commission and Board for the residents'
safe and convenient access to and utilization of the recreation, and
with safe and convenient access by adjoining street frontage or other
rights-of-way or easements capable of accommodating pedestrian, bicycle,
maintenance and vehicle traffic, and containing customary and appropriate
access improvements.

related to recreation use.
(7)
Suitably landscaped, either by retaining existing natural cover and wooded areas and/or by a landscaping plan designed to enhance recreation areas by utilization of plantings which are consistent with the purposes of this section, which minimize maintenance costs and which comply with minimum applicable landscaping requirements of Chapter 200, Zoning, of the Code of the Township of East Whiteland.
D.
Preservation of natural features. It shall be incumbent upon the developer to preserve and protect all natural features within open space and recreational areas, such as trees, watercourses, natural drainage areas, historic features and structures and similar community assets. The provisions of § 175-41C shall be observed. All other natural vegetation shall be retained and protected to the greatest extent possible and natural grade alterations shall be kept to a minimum.
A.
Buffers. Where required by Chapter 200, Zoning, of the Code of the Township of East Whiteland to be provided, the buffer yard shall be a landscaped area free of structures, materials and vehicular parking. No driveways or streets shall be permitted in the buffer yard except at points of ingress or egress.
(1)
All buffer yards shall include a completely planted
visual barrier or landscape screen. Such visual barrier shall be fully
attainable within 18 months after planting.
(a)
Existing tree masses shall be retained unless
removal of any trees therefrom is approved by the Board. A tree mass
is a grouping of six or more trees growing in relatively close proximity
to each other, two or more of which have a DBH of 12 inches or greater.
When required by the Board, such trees shall be cleared of any undesirable
flora (vines, etc.) under tree and shrub growth.
(b)
Where the existing tree masses do not fully
screen the buffer area or where there are no existing tree masses,
trees, both deciduous and coniferous shall be added to complete the
visual barrier. If the visual barrier is not created within the required
eighteen-month period following planting, additional trees shall be
added by the developer within the eighteen-month period so as to complete
the visual barrier.
(c)
The landscape screen shall be composed of both
high level and low level plantings.
[1]
The high level screen shall consist of a combination
of evergreen (coniferous) trees (initially not less than eight feet
in height) and deciduous trees [initially with caliper of not less
than 2 1/2 inches (measured one foot from ground level)]. Trees
shall be planted in staggered rows. Coniferous trees shall be planted
on ten-foot centers and deciduous trees shall be planted on eighteen-foot
centers.
[2]
The low level screen shall consist of evergreen
shrubs (initially not less than three feet in height). Shrubs shall
be spaced in staggered rows and centered no more than five feet apart.
(3)
In all buffer yards, the exterior width beyond the
planting screen shall be planted with grass seed, sod or ground cover
and shall be maintained and kept clean of all debris, rubbish, weeds
and tall (no more than 12 inches) grass.
(4)
Planted areas shall be irrigated either by a permanent
water system or by hose. Irrigation plans, including pipe size and
length, layout and type of head, shall be approved by the Township.
(5)
The developer shall guarantee required plantings in the buffer yard for 18 months from the date of dedication or close out of the construction escrow account by posting financial security for 18 months in the amount of 15% of the actual cost of the installed plantings. In the event additional plantings are required to complete the buffer screening and the developer fails to plant the additional trees or other plantings within the required period provided for in Subsection A(1)(b) of this section, the Township shall have the right to expend such portion of the required maintenance security to complete the necessary plantings.
(6)
Care and maintenance of buffer yard, including plantings,
shall be the sole responsibility of the property owner.
B.
Community assets. The development plan shall incorporate design features which preserve and protect natural features, such as large trees, as controlled by Subsection C of this section, watercourses, historic features and structures, and similar community assets, even if the retention of such features results in a reduction of the number of lots or buildings otherwise permitted by the applicable zoning district regulations of Chapter 200, Zoning, of the Code of the Township of East Whiteland.
C.
Existing trees. Developments shall be designed to
preserve the maximum number of existing trees consistent with the
reasonable development of the tract and in strict compliance with
this section.
(1)
Neither portions of tree masses nor specimen trees
shall be cleared unless absolutely necessary, and then only with the
Board's approval. In no event shall any trees be cleared from any
flood hazard area. Developer shall make all reasonable efforts to
harmonize their plans in order to preserve these existing trees.
(2)
When effectuation of a proposed subdivision and/or
land development necessitates the clearing of trees or portions of
tree masses, developer shall be guided by the following criteria in
selecting trees and ornamentals for retention or clearing:
(a)
Aesthetic values (autumn coloration, type of
flowers and fruit, bark and crown characteristics, amount of die back
present).
(b)
Susceptibility of tree to insect and disease
attack and to air pollution.
(c)
Species longevity.
(d)
Wind firmness and characteristic of soil to
hold trees.
(e)
Wildlife values (e.g., oak, hickory, pine, walnut,
and dogwood have high food value).
(f)
Comfort to surroundings (e.g., hardwoods reduce
summer temperatures to surrounding area more effectively than pines
or cedars).
(g)
Existence of disease, rot, or other damage to
the tree.
(h)
Protection of buildings (e.g., dead and large
limbs hanging over buildings shall be removed).
(i)
The size of the tree at maturity.
(3)
Developer shall exercise care to protect trees which
remain from damage during construction. The following procedures shall
be adhered to in order to preserve the remaining trees and shall be
noted on the plan. All remedial work shall be performed by qualified
personnel.
(a)
Where existing ground levels are raised, drainage
tile will be placed at the old soil level and open into a well built
around the base of the tree. Such wells may be left open or can be
filled with coarse stones or gravel. Tiles may be installed in a radiating
pattern or laid in parallel lines. Where existing ground levels are
to be lowered, a retaining wall must built around the tree.
(b)
Those trees which have been delineated on the
plan and are within 25 feet of a proposed building excavation or other
locations deemed appropriate by the Township Engineer shall be protected
by installing and maintaining a fence to the drip line.
(c)
No boards or other material shall be nailed
to trees during construction.
(d)
Heavy equipment operators shall avoid damaging
existing tree trunks and roots. Feeder roots shall not be cut closer
than 25 feet from tree trunks.
(e)
Tree trunks and exposed roots damaged during
construction shall be protected from further damage by being treated
immediately.
(f)
Tree limbs damaged during construction shall
be properly pruned and treated immediately.
(g)
The operation of heavy equipment over root systems
of such trees shall be minimized in order to prevent soil compaction.
The use of geotextiles, mulch or straw is required to protect roots
from compaction when machinery cannot avoid passing under trees, subject
to the Conservancy Board's review and approval.
(h)
Damaged trees shall be fertilized to aid in
their recovery.
(i)
Construction debris shall not be disposed of
near or around the bases of such trees.
(j)
Trenching and root pruning shall not take place
within the fenced area at the tree drip line.
(k)
Root pruning should not be done on more than
one "side" of the root system in a given year. Delay additional pruning
for at least two years following initial pruning. Optimum timing is
autumn.
(4)
Unless otherwise provided in this chapter, no more
than 20% of the trees on any wooded lot may be cut or removed. The
remaining 80% shall be retained, unless a waiver is granted by the
Board, subject to the following criteria:
(a)
The trees removed from a wooded lot cleared
or developed shall be replaced on a tree-for-tree basis. Replanting
shall be done in accordance with a plan prepared by a licensed landscape
architect and approved by the Township.
(b)
All replacement trees shall be three-inch caliper
minimum and the Township will select the type of tree to be used for
replacement.
(c)
Plantings required pursuant to the buffer yard
and landscaping requirements of this chapter may not be considered
in calculating the replanting requirements of this section.
D.
New trees.
(1)
All lots within a development that are vacant of trees shall have a minimum of one deciduous tree and one coniferous tree planted for each 5,000 square feet of lot area or part thereof. This requirement shall be in addition to any minimum tree planting requirement imposed by any provision of this chapter or Chapter 200, Zoning, of the Code of the Township of East Whiteland related to required street trees, screening and/or parking lot areas.
(2)
