1.
The provisions of this article are enacted:
A.
To encourage a more efficient use of land and public services and
to reflect changes in the technology of land development so that the
economies so secured may inure to the benefit of those who need homes.
B.
To encourage more flexible land development which will respect and
conserve natural resources such as soils suitable for agriculture,
streams, lakes, floodplains, wetlands, ground water, wooded areas,
steeply-sloped area; historic sites and areas of unusual beauty or
importance to the natural ecosystem.
C.
To provide greater opportunities for better housing, recreation and
the conservation of land for all who are or will be residents of the
Township.
D.
To encourage innovations in residential development and renewal so
that the demand for housing may be met by a greater variety in type
and design of dwellings, which minimize energy consumption; maximize
recycling of materials in their layout, transportation, climate control,
energy sources, and solid and liquid waste treatment systems; and
conserve land with efficient use of open space ancillary to said dwellings.
E.
In aid of these purposes, to provide a procedure which can relate
the type, design and layout of residential development to the particular
site and the particular demand for housing existing at the time of
development in a manner consistent with the preservation of the property
values within existing residential areas, and to assure that the increased
flexibility of regulations over land development established hereby
is carried out pursuant to sound, expeditious and fair administrative
standards and procedures.

in relation to other units in a building particularly with respect
to the use of exterior building materials, roof lines and design,
alteration of unit width, front facade setbacks, fenestration and
other design elements. Each community shall have a minimum of three
harmonious architectural facades. No two adjacent buildings shall
have similar architectural facades.
B.
Building Offsets. Single-family detached, single-family semi-detached,
townhouse and garden apartment structures shall be so arranged as
to avoid a continuous linear mass of building frontages. Setbacks
shall be varied and multi-dwelling structures, where practicable,
shall be offset or skewed in relationship to each other, roadways
or parking areas.
(1)
Where single-family detached units or single-family semi-detached
units are proposed, front building lines for adjacent units shall
be varied by a minimum of four feet to avoid a linear row development.
(2)
In all front elevations of multi-dwelling structures, there
shall be no more than two units in any unbroken line. A minimum offset
of four feet shall be required along the front building line.
C.
Building Orientation. No building shall be situated so as to face
the rear of any building within the development or adjacent properties
unless there is provided a minimum distance of 150 feet between said
building or there is an intervening visual, permanent and all season
screen, buffer or barrier separating the buildings, and acceptable
to the Township.
D.
Sheltered Parking. All residential units are to include sheltered
parking space(s) attached to or within the structure and providing
for a minimum of one vehicle. In addition, all such dwelling units
shall include a secure storage area of at least 40 square feet directly
accessible from the outside by a door at least three feet in width.
E.

units, a median strip, with a minimum width of three feet, shall be
constructed along the center of the driveway and landscaped with low
growing evergreen shrubbery. Joint responsibility for the maintenance
of the median strip shall remain with the adjacent property owners,
and further governed by the by-laws and regulations of the homeowner
association.
F.
Construction. The construction of all dwelling units shall comply
with the requirements of state, county or Township agencies, and in
strict accord with BOCA particularly as it concerns itself with the
origin and spread of fire.
4.
Site Design, Bulk, and Location Standards.
A.
General Site Design.
(1)
A well planned residential development, integrated with existing
social and natural processes, and making efficient use of common services,
should be an asset to the community. The site designer and architect,
working together, must demonstrate to the satisfaction of the Township
Supervisors that they consider both the opportunities provided and
the constraints imposed by the existing natural and social features
both on and off the site of the proposed development, in the determining
site layout (including the selection of areas for open space) and
design of structures. Each must consider, for example, the effects
of prevailing winds, seasonal temperatures and hours of sunlight in
both site design and architecture.
(2)
In order to determine which specific area of the total planned
residential development site are best suited for high density development,
which areas are best suited for lower density development, and which
areas should be preserved in their natural state as open space areas,
a thorough analysis of the physical and natural features of the site
and the Township Comprehensive Plan will be required. The information
from this analysis, submitted during the sketch plan, preliminary,
and final approval stages, shall include but not be limited to, areas
of concern such as hydrology, geology, soils, topography, vegetation
and wildlife, green belts, and micro climate.
(3)
The Board of Supervisors shall require site planning to be in
accordance with the results of such analysis, and may require modifications
where, in its opinion, site planning has been insufficiently attentive
thereto.
B.
Site Design.
(1)
All housing shall be designed with regard to the topography
and natural features of the site.
(2)
All housing shall be sited so as to enhance privacy and ensure
natural light for all principal rooms.
(3)
Variations in setbacks shall be provided where necessary to
create a more pleasing layout.
(4)
Housing and other facilities near the periphery of the planned
residential development shall be designed so as to be harmonious with
neighboring areas.
(5)
The maximum height of any structure within the planned residential
development shall be limited to 35 feet.
(6)
No single-family structure shall be less than 150 feet from
tract boundaries except that where the property line abuts an existing
Township or state maintained road, no structure shall be less than
110 feet from the center line of such road. The Board of Supervisors
may require that multi-dwelling structure within the planned residential
development be located at greater than 150 feet setbacks from tract
boundaries in order to protect the neighboring areas. Generally, the
greater the bulk of the structure, the greater the setback should
be.
(7)
There shall be no more than six single-family attached dwelling
units in a row, and no structure shall be within 50 feet of any other
structure.
(8)
The maximum linear frontage of any multi-dwelling structure
shall not exceed 160 feet.

(1)
Where storm sewers and culverts are required, installations
shall be provided to:
(2)
Stormwater inlets and culverts shall be required only when the
runoff stormwater cannot be satisfactorily handled within the street
cartway or when surface water velocities are excessive. Storm drainage
is required to drain any roadway exceeding a slope of 6%.
(3)
Where existing storm sewers are reasonably accessible, proposed
developments shall be required, if necessary, to connect therewith.
(4)
In the design of storm drainage facilities, special consideration
shall be given to avoidance of problems which may arise from the concentration
of stormwater runoff into adjacent developed or undeveloped properties
and streets. Neither pipes nor swales shall be directed to discharge
concentrated flows at tops of steep slopes (greater than 6%).
(5)
Storm drainage facilities should be designed not only to handle
the anticipated peak discharge from the property being developed,
but also the anticipated increase in run-off that will occur when
all the property at a higher elevation in the same watershed is fully
developed.
(6)
The rate of stormwater runoff from any planned residential development
shall not exceed the rate of runoff prior to development.
(7)
In addition to detention-retention basins, other techniques
for controlling the rate and quantity of stormwater runoff may be
utilized.
(8)
Where feasible, detention capacity shall be designed with sufficient
storage capacity to provide for use as auxiliary water source in event
of fire.
(9)
Where a development is traversed by a watercourse, drainageway,
channel, or stream, there shall be provided a drainage easement conforming
substantially with the high water line of such watercourse attributable
to a flood of one-hundred-year frequency, in order to preserve the
unimpeded flow of natural drainage, and to provide for future possible
widening, deepening, relocating, improving or protecting of such drainage
facilities. Calculation of the one-hundred-year level by the developer's
engineer and any proposed changes in the existing drainageway shall
be subject to the approval of the Township Engineer and the Pennsylvania
Department of Environmental Protection.
(10)
The developer shall submit routing calculations, cross-section
drawings and assumptions pertaining to cover, direction of flow, location
of recharge structures, timing of recharge, location of retention
basins, water levels, and release timing that summarize compliance
with the above requirements during the preliminary and final approval
stages.
(12)
All storm drainage design shall be subject to the approval of
the Township Engineer.
K.
Utilities. All utilities shall be underground unless such placement
is deemed not feasible by the Board of Supervisors.
L.
Erosion and Sedimentation Control.
(1)
All earth-moving activities occurring on the tract shall be conducted in accordance with an erosion and sedimentation strategy. This strategy shall be in the form of a written report and shall accompany the conservation plan erosion and sedimentation control strategy, set forth in § 27-2605, Subsection 7, of this article, which must be submitted as part of the preliminary and final development plan.
(2)
The erosion and sedimentation control strategy shall be in accordance
with the following standards:
(a)
It shall be prepared by a person duly qualified by education
and experience in the techniques and methods of erosion and sedimentation
control.
(b)
It shall employ the guidelines for minimizing erosion and sedimentation
as set forth in the Soil and Erosion Control Manual of the Pennsylvania
Department of Environmental Protection prepared by the State Conservation
Commission and Bureau of Water Quality Management and the USDA Soil
Conservation Service, as amended. In developing a strategy for the
control of erosion and sedimentation, the developer/agent shall meet,
as a minimum, the standards and specifications outlined in the aforementioned
manual.
(c)
Both during and after construction, the clearing of vegetation,
earthmoving or other surface disturbance activities, total water-borne
sediment leaving the site, and/or entering a watercourse on the site,
shall not exceed the amount of sediment which would have naturally
left the site prior to surface-disturbing activities, assuming in
the case of sites previous tilled that natural conditions are equivalent
to meadow.
(3)
Periodic inspections of the site during construction may be
conducted by the Thornbury Township Supervisors or their representatives
and any observed violations of this article shall be cause for immediate
issuance of an order to cease construction activity until such conditions
are corrected.
M.
Landscaping and Buffers.
(1)
General Landscaping.
(a)
The amount, density, and types of plantings shall be based upon
physiographic features, proximity of existing dwellings, compatibility
of adjacent uses and natural views. Where adjacent property has been
developed in such a manner that privacy from the PRD is desirable,
the planting strip adjacent thereto shall be of sufficient density
and contain sufficient plant material to effectively screen the portions
of the PRD from which privacy is desired for all seasons. In other
areas, particularly where physiographic or environmental features
and existing vegetation provide an attractive setting, the planting
strip may be left in its natural state or enhanced with additional
plant material of lesser density than a full screen.
(b)
No plantings shall be placed with their center closer than five
feet from a property line of the tract.
(c)
Plantings shall be permanently maintained and replaced in event
of death if necessary to maintain an effective screen in accordance
with the management of common open space.
(d)
Disturbed topsoil shall be stockpiled, protected from erosion
and replaced after construction.
(e)
Planting and protection of landscape material shall be in accordance
with a plan and schedule subject to Township approval, and shall be
completed within six months of initial occupancy of each stage of
development. Maintenance specifications for all plant material shall
be submitted as part of the preliminary approval stage.
(2)
Buffers. Buffering serves to soften the outline of buildings,
to screen glare and noise, and to create a visual and/or physical
barrier between conflicting land uses. The extent of buffering is
determined by the type of use proposed and the adjacent uses or streets
surrounding the proposed development. The impact of the proposed use
on adjoining properties is the basis for establishing buffer and planting
strip standards. Staging and timing of buffer planting will be coordinated
through consultation and discussion with the Board of Supervisors.
(a)
On the planned residential development tract a one-hundred-foot
buffer area is required around the tract's perimeter as it abuts other
land uses, and a fifty-foot buffer is required along existing public
rights-of-way.
(b)
To determine the required buffer area treatment, a three step
procedure shall be followed:
|
Step 1
|
Site Analysis and Determination of Buffer Area Class
| |
|
Step 2
|
Selection of the Planting Option for the Buffer Class
| |
|
Step 3
|
Selection of the Plant Materials from the Plant Materials List
|
(c)
Step 1. Site Analysis and Determination of Buffer Area Class.
1)
For each property boundary, the applicant shall identify the
adjacent land use or road classification. The land use should be determined
by the Township's Zoning Map, on-site survey, and the Highway Classification
Section in the Township's Comprehensive Plan. Table 1, following,
specifies the buffer area class for each boundary.
2)
The applicant shall match his proposed land use with the corresponding
adjacent land use or road classification for each property boundary,
as outlined in Table 1. The letter indicates the buffer area class.
(d)
Step 2. Selection of the Planting Option for the Buffer Class.
1)
After determining the buffer class, the applicant shall select
a planting option from Table 2. For each buffer class, several planting
options are available, one of which the applicant shall select to
meet the buffer area requirement for each boundary.
(e)
Step 3. Selection of Plant Materials from the Plant Materials
List.
1)
Each planting option may utilize any of the plant materials
outlined in Table 3.
2)
Minimum plant size, given either in height or in caliper, is
indicated on this table. The Township Supervisors may permit other
planting types if they are hardy to the area, are not subject to blight
or disease, and are of the same general character and growth habit
as those listed in Table 3. All planting material shall meet the standards
of the American Association of Nursureymen.
3)
The applicant may not be required to provide additional buffering
or a planting strip should existing plantings, topography, or man-made
structures, be deemed acceptable for screening purposes by the Board
of Supervisors.

Landscape Plan. The landscaping and buffering procedure for
planting and maintenance shall be outlined in a written report, which
shall be presented to the Planning Commission and submitted for preliminary
approval to the Board of Supervisors.
(4)
General Requirements.
(a)
Existing Buffer. All existing deciduous and coniferous trees
larger than two inches in caliper and/or six feet in height may be
considered to contribute to the definition of an existing buffer on
the property. If the amount of existing plant material that size or
greater equals any of the above planting requirements for reducing
buffer sizes, the equivalent reduction may be taken without additional
plant material being required. In all cases, existing plant material
of the above caliper and height shall be preserved in any buffer area
except where clearance is required to insure adequate sight distance.
Any removal shall, where feasible, involve relocation rather than
clearing.
(b)
The buffer area may overlap the required front, side, or rear
yards and in case of conflict, the larger area requirements shall
apply.
(c)
All buffer areas shall be maintained and kept clean of all debris,
rubbish, weeds and tall grass by the homeowners' condominium association
or other group responsible for management of common open space.
(d)
No structure, manufacturing or processing activity, or storage
of material shall be permitted in the buffer area, unless waived by
the Board of Supervisors.
(5)
Plant Materials.
(a)
Plant materials shall be permanently maintained and any plant
material which does not live shall be replaced within one year of
installation by the homeowners condominium association or other group
responsible for management of common open space.
(b)
Planting Design. It is encouraged that plant materials in buffer
areas be planted in natural clusters that will give privacy but do
not block views or vistas. Where external nonresidential uses abut
the PRD and where the on-tract commercial site is located, dense visual
screening is required.
(c)
All trees shall be twice transplanted, nursery grown of specimen
quality, free of insect pests and disease. They shall be of symmetrical
growth or typical of the variety and supplied from sources in the
same hardiness zone as the development is located. All plant materials
shall conform with horticultural standards established by the American
Association of Nurserymen.
(6)
Residential Uses.
(a)
The buffer area may be encroached upon provided that the applicant/developer
demonstrates, to the satisfaction of the Planning Commission and the
Board of Supervisors, that said encroachment can be mitigated by supplemental
plants and screening.
(b)
Where open space is required, the buffer area shall be part
of the open space and not part of the lot area assigned to a dwelling
unit.
N.
Conservation of Trees and Natural Features.
(1)
The development shall be designed and programmed so as to minimize
earthmoving, erosion, tree clearance, and the destruction of natural
amenities.
(2)
Existing trees shall be preserved wherever possible. The protection
of trees of four-inch caliper or over and of ornamentals shall be
a factor in determining the location of open space, buildings, underground
services, walks, paved areas, playgrounds, parking areas and finished
grade levels.
(3)
Developers shall exercise care to protect remaining trees from
damage during construction. The following procedures shall be followed
in order to protect remaining trees:
(a)
Where existing ground levels are lowered, a circular retention
wall of sufficient size shall be built around the tree to maintain
the old soil level. Where existing ground levels are raised, drainage
tiles shall be placed at the old soil level and open into a permanent
well built around the base of the tree. Such well may be left open
or can be filled with coarse stones (at least two inches). Tiles must
be installed in a radiating pattern.
(b)
Trees within 25 feet of a building site or bordering entrances
or exits to building sites shall be protected by wiring wooden slates
or snow fencing around each tree.
(c)
No boards or other material shall be nailed to trees during
construction.
(d)
Heavy equipment operators shall be warned to avoid damaging
existing tree trunks and roots. Feeder roots shall not be cut closer
than the tree drip line.
(e)
Tree trunks and exposed roots that are damaged during construction
shall be protected from further damage by being treated immediately
in a suitable manner.
(f)
Tree limbs damaged during construction shall be sawed flush
to tree trunks and the tree or trunk shall be treated immediately
in a suitable manner.
(g)
The operation of heavy equipment over root systems of such trees
shall be minimized in order to prevent soil compaction.
(h)
Non-dormant trees shall be given a heavy application of fertilizer
to aid in their recovery from possible damage caused by construction
operations.
(i)
Except for mulched vegetation matter used to prevent soil compaction,
construction debris shall not be disposed of near or around the bases
of such trees or foundations of houses.
O.
Standards for Location, Use, Ownership, and Maintenance of Open Space.
(1)
Location and Use of Open Space.
(a)
The open space shall be located so as to be consistent with
the objectives set forth in the application for planned residential
development. Where possible, it shall be designed as a contiguous
area easily accessible to the residents, preserving natural features
and conforming to the open space in surrounding properties. Open space
area should include both active recreation areas for all age groups
and, particularly where the site includes a watercourse or hilly or
wooded areas, land which is left as a natural area.
(b)
All areas designated as Floodplain Conservation Districts on the Township Zoning Map are already considered open space under existing residential zoning. Therefore, only half of the floodplain in a PRD can be used for the open space designation and to calculate the density in accordance with § 27-2604, Subsection 2, of this article.
(c)
The designated active recreation area, which shall be at least
4% of the total PRD tract areas, shall be included within the open
space. Such recreation use may include, but not be limited to, all
purpose playing fields, swimming pools, tot-lots and picnic areas
for residents of the development. The recreation area shall be located
on land of no more than 6% grade, unless permitted otherwise by the
Board of Supervisors.
(d)
Should it be determined by the Board of Supervisors that active
recreation needs of the development residents and the general public
would best be served by expanded, developer-sponsored, on-site or
off-tract area facilities, the Board of Supervisors may consider a
slight bonus increase in permitted density. The Board of Supervisors
may also find it in the public interest to accept cash-in-lieu of
recreation amenity installations on-site.
(e)
The preliminary and final plans shall 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:
1)
Lawn. A grass area, a maximum of six inches in height, 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
tidy appearance.
2)
Natural Area. An area of natural vegetation undisturbed during
construction, or replanted; such areas may contain pathways. Meadows
shall be maintained as such. Maintenance may be minimal but shall
prevent the proliferation of undesirable plants, litter, dead trees
and brush shall be removed and streams kept in free-flowing conditions.
Spraying of treated effluent is permitted within natural areas.
3)
Recreation Area. An area designated for a specific recreational
use including but not limited to tennis, swimming, shuffle board,
playfields, and totlots. Such areas shall be located and maintained
in such manner as not to create a hazard or nuisance and shall support
the active use by the PRD residents.
(f)
Designated planting and recreation facilities within the open
space areas shall be provided by the developer. A performance bond
or other securities may be required to cover costs of installation
in accordance with this article.
(2)
Ownership and Maintenance of Open Space.
(a)
Ownership. There shall be provisions which ensure that the open
space land shall continue as such and be properly maintained. Any
of the following methods may be used either individually or in combination
to preserve, own and maintain open space: condominium, homeowners
association, dedication in fee-simple, easements and transfers to
a private conservation organization. Such land shall not be eligible
for transfer to another party or be disposed by sale or other wise,
without first offering to dedicate the same to the public. Such land
may be transferred to another method of ownership permitted herein,
and then only when there is no change in the open space ratio. The
following specific requirements are associated with each of the various
methods:
1)
Condominium. The open space may be controlled through the use
of condominium agreements. Such agreement shall be in conformance
with the Uniform Condominium Act, 68 Pa.C.S.A. § 3101 et
seq. All open space land shall be held as "common element."
2)
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 herein.
3)
Fee-Simple Dedication. The Township may, but shall not be required
to, accept any portion or portions of the open space provided:
4)
Dedication and Easements. The Township may, but shall not be
required to, accept easements for public use of any portion or portions
of open space land, title of which is to remain in ownership by condominium
or homeowners association, provided:
5)
Transfer of Easements to a Private Conservation Organization.
With permission of the Township, an owner may transfer easements to
a private, nonprofit organization, among whose purposes is to conserve
open space land and/or natural resources, provided that:
[a]
The organization is acceptable to the Township,
and a bona fide conservation organization with perpetual existence.
[b]
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.
[c]
A maintenance agreement acceptable to the Township
is entered into by the developer and the organization.
(b)
Specific Requirements for Homeowners Association. If a homeowners
association is formed, it shall be governed according to the following
regulations:
1)
The developer shall provide a description of the organization
including its by-laws and methods for maintaining the open space for
each property owner.
2)
The organization is established by the developer and operating
with financial subsidization by the developer, if necessary, before
the sale of any lots within the development.
3)
Membership in the organization is mandatory for all property
owners therein and their successors.
4)
The organization shall be responsible for maintenance of insurance
and taxes on open space.
5)
The members of the organization shall share equitably the costs
of maintaining and developing such open space, in accordance with
the procedures established herein.
6)
In the event of any proposed transfer, within the methods herein
permitted, of open space land by the homeowners association, or of
the assumption of maintenance of open space land by the Township as
hereinafter provided, notice of such action shall be given to all
property owners within the planned residential development.
7)
The organization shall have or hire adequate staff to administer
common facilities and maintain the open space.
8)
The property owners organization may lease back open space land
to the developer, his heirs, or assigns, or to any other qualified
person, or corporation, for operation and maintenance of open space
lands, but such a lease agreement shall provided:
[a]
That the residents of the planned residential development
shall at all times have access to the open space lands contained therein.
[b]
That the open space leased shall be maintained
for the purposes set forth in this article.
[c]
That the operation of open space facilities may
be for the benefit of the residents only, or may be open to the residents
of the Township, at the election of the developer and/or the property
owners organization, as the case may be.
9)
The lease shall be subject to the approval of the Board of Supervisors
and any transfer or assignment of the lease shall be further subject
to the approval of the Board. Lease agreements so entered upon shall
be recorded with the Recorder of Deeds of Delaware County within 30
days of their execution and a copy of the recorded lease shall be
filed with the Secretary of the Township.
(c)
Maintenance.
1)
A sanitary sewer system and/or water supply system shall be
maintained by the developer, his successors or assigns as approved
by the Board of Supervisors, unless the development will be served
from the time the final plan is approved by a public sanitary sewer
system and/or a public water supply system, and shall meet all applicable
regulations of the Pennsylvania Department of Environmental Protection.
2)
In the event that the organization established to won and maintain
open space or any successor organization, shall at any time after
establishment of the planned residential development fail to maintain
the open space is reasonable order and condition in accordance with
the development plan, the Township may serve written notice upon such
organization or upon the residents and owners of the planned residential
development setting forth the manner in which the organization has
failed to maintain the open space in reasonable condition, and said
notice shall include a demand that such deficiencies of maintenance
be remedied within 30 days thereof, and shall state the date and place
of a hearing thereon which shall be held within 14 days of the notice.
At such hearing, the Township may modify the terms of the original
notice as to the deficiencies and may give an extension of time within
which they shall be cured. If the deficiencies set forth in the original
notice or in the modifications thereof shall not be remedied within
said 30 days or any extension thereof, the Township, in order to preserve
the taxable values of the properties within the planned residential
development and to prevent the open space from becoming a public nuisance,
may enter upon said open space and maintain the same for a period
of one year. Said entry and maintenance shall not vest in the public
any rights to use the open space except when the same is voluntarily
dedicated to the public by the residents and owners. Before the expiration
of said year, the Township shall, upon its initiative or upon the
request of the organization theretofore responsible for the maintenance
of the open space, call a public hearing upon notice to such organization,
or to the residents and owners of the planned residential development
to show cause why such maintenance by the Township shall not, at the
election of the Township, continue for a succeeding year. If the Township,
shall determine that such organization is ready and able to maintain
said open space in reasonable condition, the Township shall cease
to maintain said common space at the end of said year. If the Township
shall determine such organization is not ready and able to maintain
said open space in a reasonable condition, the Township may, in its
discretion, continue to maintain said open space during the succeeding
year and subject to a similar hearing and determination in each year
thereafter. The decision of the Township in any such case shall constitute
a full administrative decision subject to judicial review.
3)
The cost of such maintenance by the Township shall be assessed
ratably against the properties within the planned residential development
that have a right of enjoyment of the open space and shall become
a tax lien on said properties. Said assessments and/or charges shall
be subordinate in lien to the lien of any mortgages on the property
which is subject to such assessments or charges regardless of when
said mortgage or mortgages were created or when such assessments or
charges accrued; provided that such subordination shall apply only
to assessments or charges that have been payable prior to the passing
of title under foreclosure of such mortgage or mortgages, and the
transferee shall not be liable for payment of any assessments or charges
accruing prior to said foreclosure, but nothing herein shall be held
to affect the rights herein given to enforce the collection of such
assessments or charges accruing after sale under foreclosure of such
mortgage or mortgages; and provided, further, that such charges accruing
after sale shall also be subordinate in lien to the lien of any further
mortgage or mortgages whatsoever on such property. The Township, at
the time of entering upon said open space for the purpose of maintenance,
shall file a notice of such lien in the office of the Prothonotary
of Delaware County, upon the properties affected by such lien within
the planned residential development.
P.
Development in Stages. A developer may construct a planned residential
development in stages if the following criteria are met:
(1)
The application for preliminary approval covers the entire planned
residential development and show the location and approximate time
of construction for each stage, in addition to other information required
by this article.
(2)
At least 15% of the dwelling units in the plan given preliminary
approval are included in the first stage and are properly connected
to water supply and sanitary sewer disposal systems.
(3)
At least 33% of the dwelling units in any stage are occupied
before any commercial development shown in that stage shall be completed.
(4)
The second and subsequent stages are completed consistent with
the preliminary approved plan and are of such size and location that
they constitute economically sound units of development. In no event
shall such stages contain less than 15% of the dwelling units receiving
preliminary approval.
(5)
Gross residential density may be carried from stage to stage,
provided, however, that final approval shall not be given to any stage
if the gross residential density by type of dwelling of the area which
includes stages already finally approved and the stage for which final
approval is being sought exceeds by more than 10% the gross residential
density for each type of dwelling unit allowed for the entire planned
residential development in the preliminary approved plan. Where it
is necessary to allocate open space to early stages to avoid exceeding
maximum gross residential densities, the developer will be required
to grant an open space easement or covenant to the Township specifying
the amount and, if necessary, the location of open space.
(6)
Where development in stage is applied for and approved, the
developer shall have completed the planting of the planting strips
before approval of subsequent stages can be granted.

The Findings.
A.
The Board of Supervisors, within 60 days following the conclusion
of the public hearing shall, by official written communication, to
the landowner/applicant, either:
(1)
Grant preliminary approval to the development plan as submitted.
(2)
Grant preliminary approval subject to specified conditions not
included in the development plan as submitted.
(3)
Deny preliminary plan approval to the development plan. Failure
to so act within said period shall be deemed to be a grant of preliminary
approval of the development plan as submitted. In the event, however,
that preliminary approval is granted subject to conditions, the landowner
may, within 30 days after receiving a copy of the official written
communication of the Board of Supervisors, notify the Board of Supervisors
of his refusal to accept all said conditions, in which case the Board
of Supervisors shall be deemed to have denied tentative approval of
the development plan. In the event the landowner does not, within
said period, notify the Board of Supervisors of his refusal to accept
all said conditions, preliminary approval of the development plan,
with all said conditions, shall stand as granted.
B.
The grant or denial of preliminary approval by official written communication
shall include not only conclusions but also findings of fact related
to the specific proposal and shall set forth the reasons for the grant,
with or without conditions, or for the denial, and said communication
shall set forth with particularity in what respects the development
would or would not be in the public interest including but not limited
to findings of fact and conclusions on the following:
(1)
Those respects in which the preliminary development plan is
or is not consistent with the Comprehensive Plan for the development
of the Township.
(2)
The extent to which the development plan departs from Zoning
and Subdivision regulations otherwise applicable to the subject property,
including but not limited to density, bulk and use, and the reasons
why such departures are or are not deemed to be in the public interest.
(3)
The purpose, location and amount of the open space in the planned
residential development, the reliability of the proposals for maintenance
and conservation of the open space, and the adequacy or inadequacy
of the amount and purpose of the open space as related to the proposed
density and type of residential development.
(4)
Maintenance of sewage and water systems.
(5)
The physical design of the development plan and the manner in
which said design does or does not make adequate provision for public
services, provide adequate control over vehicular traffic, and further
the amenities of light and air, recreation and visual enjoyment.
(6)
The relationship, beneficial or adverse, of the proposed planned
residential development of the neighborhood in which it is proposed
to be established.
(7)
In the case of a preliminary development plan which proposed
development over a period of years, the sufficiency of the terms and
conditions intended to protect the interests of the public and of
the residents of the planned residential development in the integrity
of the development plan.
C.
In the event a preliminary development plan is granted preliminary
approval, with or without conditions, the Board of Supervisors may
set forth in the official written communication the time within which
an application for final approval of the development plan shall be
filed or, in the case of a development plan which provides for development
over a period of years, the periods of time within which applications
for final approval of each part thereof shall be filed. Except upon
the consent of the Board of Supervisors the time so established between
the grant of preliminary approval and application for final approval
shall be not less than three months nor more than one year and, in
case of development over a period of years, the time between applications
for final approval of each part of the plan shall be not less than
12 months nor more than 18 months.
3.
Status of Plan After Preliminary Approval.
A.

Where preliminary approval has been granted, the same shall be noted on the Zoning Map.
B.
Preliminary approval of a development plan shall not qualify a plat
of the planned residential development for recording nor authorize
development or the issuance of any building permits. A development
plan which has been given preliminary approval as submitted, or which
has been given preliminary approval with conditions which have been
accepted by the landowner (and provided that the landowner has not
defaulted nor violated any of the conditions of the preliminary approval),
shall not be modified or revoked nor otherwise impaired by action
of the Township pending an application or applications for final approval,
without the consent of the landowner, provided an application for
final approval is filed or, in the case of development over a period
of years, provided applications are filed, within the periods of time
specified in the official written communication granting preliminary
approval.
C.
In the event that a development plan is given preliminary approval
and thereafter, but prior to final approval, the landowner shall select
to abandon said development plan and shall so notify the Board of
Supervisors in writing, or in the event the landowner shall fail to
file application or applications for final approval within the required
period of time or times, as the case may be, the preliminary approval
shall be deemed to be revoked and all that portion of the area included
in the development plan for which final approval has not been given
shall be subject to those local ordinances otherwise applicable thereto
as they may be amended from time to time, and the same shall be noted
on the Zoning Map and in the records of the Township Secretary.

of preliminary approval, the Township shall, within 45 days of such
filing, grant such development plan final approval.
5.
In the event the final development plan as submitted contains variations
from the development plan given preliminary approval, the Board of
Supervisors may refuse to grant final approval and shall, within 45
days from the filing of the application for final approval, so advise
the landowner in writing of said refusal, setting forth in said notice
the reasons why one or more of said variations are not in the public
interest. In the event of such refusal, the landowner may either:
A.
Refile his application for final approval without the variations
objected.

a public hearing on his application for final approval. If the landowner
wishes to take either such alternate action he may do so at any time
within which he shall be entitled to apply for final approval, or
within 30 additional days if the time for applying for final approval
shall have already passed at the time when the landowner was advised
that the development plan was not in substantial compliance. In the
event the landowner shall fail to take either of these alternate actions
within said time, he shall be deemed to have abandoned the development
plan. Any such public hearing shall be held pursuant to public notice
within 30 days after request for the hearing as prescribed in this
article for public hearings on applications for preliminary approval.
Within 30 days after the conclusion of the hearing, the Board of Supervisors
shall by official written communication either grant final approval
to the development plan or deny final approval. The grant or denial
of final approval of the development plan shall, in cases arising
under this article, be in the form and contain findings required for
an application for preliminary approval set forth in this article.
C.
A final development plan, or any part thereof, which has been given
final approval shall be so certified without delay by the Board of
Supervisors and shall be filed of record forthwith in the office of
the Recorder of Deeds before any development shall take place in accordance
therewith. Upon the filing of record of the final development plan,
the Zoning and Subdivision regulations otherwise applicable to the
land included in such plans shall cease to apply thereto. Pending
completion within a reasonable time of said planned residential development
or of that part thereof, as the case may be, that has been finally
approved, no modification of the provisions of said development plan,
or part thereof, as finally approved, shall be made except with the
consent of the landowner.
6.
In the event that a final development plan, or a section thereof,
is given final approval and thereafter the landowner shall abandon
such plan or the section thereof that has been finally approved, and
shall so notify the Board of Supervisors in writing; or, in the event
the landowner shall fail to commence and carry out the planned residential
development within two years after final approval has been granted,
no development or further development shall take place on the property
included in the development plan until after the said property is
resubdivided and is reclassified by enactment of an amendment to this
chapter.
