A.
The tract of land so developed shall be in single ownership or, in
the case of multiple ownership of the tract, the application shall
be filed jointly by all of the owners of the tract and, in any case,
it shall be agreed that the tract will be developed, within the time
limits specified by the Board, under a single direction and in the
manner approved;
B.
The tract shall be located entirely in the PRD District;
C.
Tract size.
(1)
A tract in the PRD District shall have a minimum contiguous
area of 100 acres. In the event that the minimum tract acreage in
the PRD District is not contiguous due to separation by one or more
public roads or public rights-of-way, such separation shall not preclude
development of the tracts as a PRD if they are developed in a unified
manner as a single PRD.
(2)
Those portions of the tract encumbered by land conservancy easements

In order to facilitate a comprehensive review of site suitability,
the following standards shall be applied to sites being considered
for a PRD except wherein 25 acres are developed for mobile homes,
wherein the mobile home ordinance standards shall apply:
A.
Modification of otherwise applicable standards.
(1)
The uniqueness of each proposal for PRD may require that the standards and specifications in the other parts of this chapter and/or Chapter 115, Subdivision and Land Development, may be subject to modification for such features as: the width and surfacing of the streets and highways; alleys; public utilities; curbs; gutters; sidewalks; pathways/trails; streetlights; public parks and playgrounds; school grounds; stormwater drainage; water supply and distribution; sanitary sewers and sewage collection and treatment; parking spaces and areas; and setbacks and separations of structures in relation to each other and property lines.
(2)
The Board of Supervisors may modify certain standards and specifications, provided that the modifications of such standards and specifications are: consistent with the public interest; consistent with the purpose and intent of this chapter; and that such modification represents the least change to the chapter. Where there is conflict between standards and specifications of this article and other ordinance provisions, the Board of Supervisors shall determine which ordinance provisions will prevail; and where not specifically modified by the Board of Supervisors, the provisions of the other parts of this chapter and Chapter 115, Subdivision and Land Development, shall fully apply to developments under this article.
B.
General tract considerations. In order to determine which areas of
a prospective tract are suitable for development and which areas should
remain in open space, a thorough analysis of the natural and man-made
resources of the site shall be mapped and described in a written report.
The Township shall require site design proposals to address the results
of these analyses in a way which will conserve natural resources.
The analysis shall include the following inventory:
(1)
Natural features such as lakes, streams, wetlands and wooded
slopes to be preserved and incorporated into the proposed landscaping
of the development plan to the maximum extent possible. The applicant
shall demonstrate the means whereby trees and other natural features
shall be protected during construction. The location of such trees
and other natural features must be considered when planning and designing
such features as: common open space, locations of buildings, underground
utilities and services, sidewalks, pathways, paved areas and finished
grade levels.
(2)
An analysis of the watershed in which the tract is located,
including site-specific analysis of water resources such as streams,
drainage swales, floodplain areas, wetlands and areas with high water
table soils. Water bodies shall be preserved in their natural state
and incorporated into the design of the development.
(3)
An analysis of rock formation characteristics underlying the
tract, including aquifers, areas of shallow soil and rock outcroppings
and areas which are unsuitable to serve as foundation materials.
(4)
An analysis of the terrain of the tract, including the mapping
of elevation in at least twenty-foot bands on a topographic elevation
map and the delineation of slope into the following categories: 0%
to 15%, 15% to 25% and over 25% slope. The mapping of slopes shall
be performed using a two-foot contour interval aerial or field-derived
topographic survey. All moderate and steep slopes shall be mapped.
However, restrictions on use of the slopes shall apply whenever three
or more consecutive two-foot contours (six cumulative feet or more)
are impacted. Slopes exceeding 25% shall be reserved in their natural
state. Seeding, sodding and other plantings shall be applied to stabilize
steep slopes and to enhance the appearance of open areas.
(5)
Where adequate surface drainage is not possible by grading alone,
a supplementary drainage system approved by the Township shall be
required.
C.
General design guidelines. The following guidelines shall apply:
(1)
All housing shall be designed with regard to the topography
and natural features of the site. All proposed building locations
shall be set back at least 10 feet from slopes in excess of 25%, floodplain
areas and wetlands. In addition, all proposed building locations shall
be free of high water table soil types and unstable geologic formations.
The effects of prevailing winds, seasonable temperature and hours
of sunlight on the physical layout and form of the proposed development
shall be demonstrated.
(2)
Variations in the building design shall be required to create
architectural interest in the layout and character of dwellings. Such
variations may be achieved, among other ways, through the design of
buildings to include such features as porches, courtyards or atrium
spaces formed by attached dwellings or multifamily buildings and arcade/foyer
spaces formed by nonresidential buildings.
(3)
All dwellings shall be designed to ensure natural light and
ventilation, while affording maximum privacy.
(4)
Access to vehicular parking and pedestrian walks shall be convenient
to dwellings without creating a nuisance or detracting from privacy
of residents. All dwellings shall be served by local streets.
(5)
The entire perimeter of the tract(s) to be developed shall include
a landscape buffer in accordance with this article. However, if the
Design Review Committee determines that sufficient existing vegetation
and/or topography buffer and screen views of the proposed development,
the buffer requirement may not be required. All proposed residential
principal structures shall be set back from the tract boundary a minimum
distance of 100 feet, and all proposed residential accessory structures
shall be set back at least 50 feet from the tract boundary, both of
which shall be measured from the adjacent property lines, or, in the
case of a street, alley, roadway or highway, from the ultimate right-of-way
lines.
(6)
Dwelling units and lots shall be clustered to minimize the disruption
of the site and to provide for an adequate open space design.
(7)
This article is intended to encourage good quality development
by taking into consideration the appearance of all elevations and
layouts of buildings and external spaces and materials used therein.
The Design Review Committee shall evaluate the quality of development
proposed and may make recommendations to the Board to improve such
quality.
(8)
Lots, buildings, roads and other structures shall be grouped
into clusters so as to create a sense of neighborhood. A sense of
neighborhood shall be achieved by incorporating the following features
into the development plan: a neighborhood center; parks, playgrounds
or other recreation facilities within a one-fourth-mile radius of
a group or cluster of dwellings; a street, sidewalk and pathway system
designed in an integrated manner and leading to and from the neighborhood
center; and parking on the side and rear of buildings in the neighborhood
center so as to create and promote pedestrian space between the building
façades and the street lines.
(a)
A sense of neighborhood may also be created by the design and
placement of dwellings and structures in the form of a traditional
neighborhood with: buildings 25 feet from the street line and detached
garages accessible from a rear service alley; front porches; street
trees; sidewalks on both sides of the street; and pathways leading
to parks and a neighborhood center.
(9)
Development shall be located on areas of the tract to minimize
the disruption of sensitive environmental features such as hedgerows,
woodlands, steep slope areas and water bodies. These features shall
be incorporated into the common open space to provide visual screening
between clusters. Clusters of lots shall be defined and separated
by common open space in order to allow direct access to open space
and recreational facilities. The common open space between clusters
shall have a minimum width of 100 feet. A minimum setback of 20 feet
from the exterior walls of all multiple-dwelling structures shall
be achieved in order to define the boundary of the common open space
close to proposed buildings.
(11)
Historic resources, as shown on the Thornbury Township Historic
Resources Map,[1] shall be protected and, when not proposed as a residence,
shall be preserved in a setting surrounded by open space. The applicant's
proposal for protection and preservation shall include provisions
for future ownership and maintenance approved by the Design Review
Committee.
[1]
Editor's Note: Said map is on file in the Township offices.
(12)
Eighty percent of the area of the minimum required lot size
shall be outside areas subject to floodplain management, wetlands,
steep slopes, and stormwater management basins. For purposes of this
regulation, the area of a stormwater basin shall be calculated by
measuring the area of the water surface within the basin projected
to exist at the level of the basin overflow. Every lot shall be free
of wetlands, floodplains and steep slopes. Whenever this subsection
conflicts with any other provision of this section, the stricter regulation
shall apply.
D.
Optional sketch plan review and discussion.
(1)
Although optional, the applicant is strongly urged to submit
a sketch plan for review and discussion with the Township.
(3)
The sketch plan shall include typical elevations of the proposed
buildings.
(4)
The sketch plan review and discussion process is intended to
provide the Thornbury Township Board of Supervisors, Planning Commission
and Design Review Committee with an opportunity to engage in a meaningful
analysis of design issues, alternatives and options.
(5)
Through the review and discussion of the sketch plan, the applicant
and the Township can explore conceptual design solutions for ingress/egress,
vehicular and pedestrian circulation, open space, recreational areas,
the use of developable areas, the relationship of developable areas
to one another, the location and form of the design to create a sense
of neighborhood and other matters.
The applicant shall be responsible for the preparation of the
following impact studies. These studies shall be submitted as part
of the application for tentative plan approval. This supporting data
shall be designed to assist the Township in the review of the proposal

Mitigating measures shall include methods of maintaining the capacity of the road network within the study area. Mitigation measures shall be proposed to minimize adverse impacts, and the Board of Supervisors may condition any PRD Plan approval on such mitigation in accordance with § 155-714.
B.
Community impact study. The applicant shall submit an impact study
which will sufficiently assess the impact the development will have
on the Township and the level of public services. The study shall
address the manner in which identified negative impacts shall be mitigated
by the applicant to enable the Board of Supervisors to ascertain if
the proposed development is capable of being serviced by existing
public services and, further, to specify what efforts the applicant
has made to minimize the demand for services. The study shall analyze
the following services and facilities:
(1)
Fire protection. The impact the proposed development will have
on fire protection capability, including, but not limited to, municipal
water supply, pumping capacity and specialized equipment, shall be
analyzed. The applicant must adequately demonstrate what effect the
proposed development will have on these factors and its ability to
meet any specialized needs so that the development will not have any
impact on the public safety by adversely affecting the fire protection
capability available to the community.
(2)

(1)
The applicant of every PRD shall prepare and present at the
time of submission of the tentative development plan for the approval
of the Board of Supervisors documents creating and governing a property
owner's organization and containing the declarations of covenants,
restrictions, easements, charges and liens deemed necessary to own
and maintain the common open space and recreation areas within the
PRD.
(2)
Areas to be preserved in common open space shall be held either
individually or collectively using the following methods of ownership:
(a)
Homeowners' association. The common open space areas and their facilities may be held in common ownership by a homeowners' association. The association shall be formed and operated in accordance with the provisions of § 155-709C(3).
(c)
Fee simple dedication to the Township. The Board of Supervisors
may consider for dedication open space lands and their facilities
for public use at the time of application for PRD approval. The Township
has neither the obligation to accept such property nor the need to
require common property be dedicated as a condition for approval.
(d)
Dedication of easements. Easements within common areas along
such unique natural features as water bodies may be offered for dedication
to the Township for public use or to a private conservancy. Title
to such lands remains in ownership by homeowners' association
or condominium agreement.
(e)
Lease-back option. To encourage the retention of agricultural lands, the Township, homeowners' association or the condominium agreement may permit all or portion of the open space lands to be leased back to a farmer. Approval of the lease-back option shall be conditioned on appropriate agreements between the title holder and the farmer concerning permitted farming practices and use of land in the event that farming practices cease in addition to the requirements of § 155-710C(3).
(3)
In addition to the foregoing, these documents shall contain
the following minimum essential provisions with respect to such organization:
(a)
Powers and duties in maintaining and administering open space,

and enforcing all covenants and restrictions and in the levying, collecting
and disbursing of assessments and charges.
(b)
Membership and voting rights.
(c)
Rights and duties of the Township of Thornbury, members of the
organization and residents of the PRD in the event of a breach of
the covenants and restrictions.
(d)
If such organization is abandoned or abolished or if such organization
desires to dispose of the common open space and recreation areas,
said open space recreation areas shall be first offered to dedication
to the Township of Thornbury at no cost to the Township before it
is otherwise disposed of. The Township may refuse to accept such dedication
and elect, as provided in the next subsection, to maintain the open
space, with all costs of such maintenance being paid ratably by the
residents of the development.
(e)
In the event that the organization established to own and maintain
common open space, or any successor organization, shall at any time
after establishment of the PRD fail to maintain the common open space
in reasonable order and condition in accordance with the plan, the
Board may proceed as provided in Section 705(f)(2) of the Act[2] to demand that the deficiencies of maintenance be corrected
or that the Township will enter upon and maintain common open space.
[1]
The Township may continue to maintain such open space, as further
provided in that section of the Act, until an organization is established
by the residents of the PRD which the Board of Supervisors finds is
ready and able to maintain such common open space. Notice to affected
property owners in accordance with the provisions of the plan as required
above shall be deemed to be adequate by the Township. The cost of
such maintenance by the Township shall be assessed ratably against
the properties within the PRD that have a right of enjoyment of the
common open space and shall become a lien on said properties. The
Township, at the time of entering upon said common open space for
the purpose of maintenance, shall file a notice of lien in the office
of the Prothonotary of Chester County upon the properties affected
by the lien within the PRD.

In the event that tentative plan approval is given subject to conditions,
the landowner may, within 30 days after receiving a copy of the official
written communications of the Board of Supervisors, notify the Board
of his refusal to accept all said conditions, in which case the Board
shall be deemed to have denied tentative plan approval of the development
plan. In the event that the landowner does not, within said period,
notify the Board of his refusal to accept all said conditions, the
tentative plan approval of the development plan, with all said conditions,
shall stand as granted.
C.
The grant or denial of tentative plan 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 denial, and said
communications shall set forth with particularity in what respects
the development plan would or would not be in the public interest,
including, but not limited to, findings of fact and conclusions on
the following:
(1)
In what respects the 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 purposes, composition and amount of the common open space
in the PRD, the reliability of the proposals for maintenance and conservation
of the common 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)
The physical design of the development plan and the manner in
which said design does or does not make adequate provision for utilities
and public service, provide adequate control over vehicular traffic
and further the amenities of light and air, recreation and visual
enjoyment;
(5)
The relationship, beneficial or adverse, of the proposed PRD
to the neighborhood in which it is proposed to be established;
(6)
The adequacy or inadequacy of the provisions in the development
plan for protecting against imbalances in ecological systems, air

(8)
The probability that the applicant will be able to obtain adequate
financing to complete the development;
(9)
Special conditions that must be met, such as reserving land,
providing bonds or, in some other manner, providing for a fair contribution
by the development to utilities, schools and other public and community
facilities which will be required within the area where the development
is located; and

the PRD in the integrity of the development plan.
D.
In the event that the development plan is granted tentative plan
approval, with or without conditions, the Board may set forth in the
official written communications, the time within which an application
for final plan 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 plan approval of each part thereof shall be filed. Except upon
the consent of the applicant, the time so established between grant
of tentative plan approval and an application for final plan approval
shall not be less than three months and, in the case of development
over a period of years, the time between applications for final plan
approval of each part of the plan shall not be less than 12 months.
A.
The official written communication provided for in this article shall
be certified by the Secretary of the Township and shall be filed in
his office, and a certified copy shall be mailed to the landowner.
B.
Tentative plan approval of a development plan shall not qualify a
plan of the PRD for recording nor authorize development or the issuance
of any building permits. A development plan which has been given tentative
plan approval with conditions which have been accepted by the landowner
(and provided that the landowner has not defaulted or violated any
of the conditions of the tentative plan approval) shall not be modified
or revoked nor otherwise impaired by action of the Township pending
an application or applications for final plan approval without the
consent of the landowner, provided that an application for final plan
approval is filed or, in the case of a development over a period of
time, provided that applications are filed within the time specified
in the official written communications granting tentative plan approval.
C.
In the event that the development plan is given tentative plan approval,
and thereafter, but prior to final plan approval, the landowner shall
elect to abandon said development plan and shall so notify the governing
body, in writing, or in the event that the landowner shall fail to
file application or applications for final plan approval within the
required period of time or times, as the case may be, the tentative
plan approval shall be deemed to be revoked, and all that portion
of the area included in the development plan for which final plan
approval has not been given shall be subject to those ordinances otherwise
applicable thereto as they may be amended from time to time and shall
be noted in the records of the Secretary of the Township.
D.
By agreement of all interested parties, application for both tentative
plan and final plan approval of a development plan may be made concurrently
and both tentative plan approval and final plan approval shall be
given by the Board if said plan meets the requirements for both types
of approval.
A.
An application for final plan approval may be for all the land included in a development plan or, to the extent set forth in the tentative plan approval, for a section thereof. Said application shall be made to the Board within the time or times specified by the official written communication granting tentative plan approval. The application shall include any drawings, specifications, covenants, easements, performance bonds and such other requirements as may be specified by this article or by Chapter 115, Subdivision and Land Development, or regulations of Thornbury Township, as amended, as well as any conditions set forth in the official written communication at the time of tentative plan approval. A public hearing on an application for final plan approval of the development plan, or a part thereof, shall not be required, provided that the development plan, submitted for final plan approval, is in compliance with the development plan theretofore given tentative plan approval and with any specified conditions attached thereto.
B.
Plans submitted for final plan approval of all or a portion of the
PRD shall be prepared in accordance with the following requirements:

The proposed building setback line for each street and/or the
proposed placement of each building.
(g)

size and invert elevation of all sanitary and storm sewers and location
of all manholes, inlets and culverts, headwalls, water mains, petroleum
or petroleum product lines, fire hydrants and other significant man-made
features. The size and nature of all culverts, inlets, catch basins,
etc., and all headwalls, with the height in feet from the bottom of
the pipe indicated.

and character of the paved cartway and a typical cross section of
said cartway showing curbs and/or gutters, sidewalks and maximum bank
slopes.
(k)

and location of all utilities (e.g., electric lines, sewer and water
lines, lighting standards, pipelines, etc.) and utility easements

sidewalks and all public improvements shall be in strict accordance
with the specification and general standards of the Township of Thornbury
and the Commonwealth of Pennsylvania covering similar types of construction.

E.
In the event that the application for final plan approval has been
filed, together with all drawings, specifications and other documents
in support thereof and as required by this article and the official
written communication of tentative plan approval, the Board shall,
within 45 days of such filing, grant such development plan final plan
approval.
F.
Action on application for final approval.
(1)
In the event that the development plan as submitted contains
variations from the development plan given tentative plan approval,
the Board may refuse to grant final plan approval and shall, within
45 days from the filing of the application for final plan approval,
so advise the landowner, in writing, of said refusal, setting forth
in said notice the reasons why one or more of the said variations
are not in the public interest. In the event of such refusal, the
landowner may either:
(2)
If the landowner wishes to take either alternate action, he
may do so at any time within which he shall be entitled to apply for
final plan approval, or within 30 additional days if the time for
final plan 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 that 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 is made by the landowner, and the hearing shall be conducted
in the manner prescribed in this article for the public hearings on
applications for tentative plan approval.
(3)
Within 30 days after the conclusion of the hearing, the Board
shall by official written communication either grant final plan approval
to the development plan or deny final plan approval. The grant or
denial of final plan approval of the development plan shall, in cases
arising under this section, be in the form and contain findings required
for an application for tentative plan approval set forth in this article.
G.
A development plan, or any part thereof, which has been given final
plan approval shall be so certified without delay by the governing
body or its designated agency and shall be filed of record forthwith
by the applicant in the office of the Recorder of Deeds before any
development shall take place in accordance therewith. Upon the filing
of record of the development plan, the zoning and subdivision regulations
otherwise applicable to the land included in such plan shall cease
to apply thereto except as herein noted. Pending completion within
a reasonable time of said PRD, 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 owner.
H.
In the event that a development plan, or section thereof, is given final plan approval and thereafter the landowner shall abandon such plan or the section thereof that has been finally approved and shall so notify the Board, in writing; or in the event the landowner shall fail to commence and carry out the PRD within 12 months after final plan approval has been granted, no development or further development by the landowner shall take place on the property included in the development plan until after the said property is resubdivided; if necessary, said property may be reclassified by enactment of an amendment to the municipal zoning ordinance in the manner prescribed for such amendments. The Board further may act, pursuant to § 155-706D(8), to use the proceeds of a performance bond or bonds to satisfactorily complete all or a portion of an abandoned PRD. In the event that the Board finds that the developer is not proceeding with reasonable diligence in executing the development, it may consider the plan abandoned and proceed as provided below.
A.
To further the mutual interest of the residents of a PRD and of the
public in the preservation of the integrity of the development plan,
as finally approved, and to ensure that modifications, if any, in
the development plan shall not impair the reasonable reliance of the
said residents upon the provisions of the development plan, nor result
in changes that would adversely affect the public interest, the enforcement
and modifications of the provisions of the development plan, as finally
approved, whether those are recorded by plan, covenant, easement or
otherwise, shall be subject to the following provisions:
(1)
The provisions of the development plan relating to the following
shall run in favor of the Township and shall be enforceable in law
or equity by the Township without limitation on any powers or regulations
otherwise granted the Township by law:
(2)
All provisions of the development plan shall run in favor of
the residents of the PRD, but only to the extent expressly provided
in the development plan and in accordance with the terms of the development
plan, and to that extent said provisions, whether recorded by plan,
covenant, easement or otherwise, may be enforced at law or equity
by said residents acting individually, jointly or through an organization
designated in the development plan to act on their behalf; provided,
however, that no provisions of the development plan shall be implied
to exist in favor of residents of the PRD except as to those portions
of the development plan which have been finally approved and have
been recorded.
(3)
All those provisions of the development plan authorized to be
enforced by the Township under this section may be modified, removed
or released by the Township except grants or easements relating to
the service or equipment of a public utility, subject to the following
conditions:
(a)
No such modification, removal or release of the provisions of
the development plan by the municipality shall affect the rights of
the residents of the PRD to maintain and enforce those provisions,
at law or equity, as provided in this section.
(b)
No modification, removal or release of the provisions of the
development plan by the municipality shall be permitted except upon
a finding by the Board, following a public hearing thereon pursuant
to public notice called and held in accordance with the provisions
of this article, that the same is consistent with the efficient development
and preservation of the entire PRD, does not adversely affect either
the enjoyment of land abutting upon or across the street from the
PRD or the public interest and is not granted solely to confer a special
benefit upon any person.
(4)
Residents of the PRD may, to the extent and in the manner expressly
authorized by the provisions of the development plan, modify, remove
or release their rights to enforce the provisions of the development
plan, but no such action shall affect the right to the Township to
enforce the provisions of the development plan in accordance with
the provisions of this section.
B.
Violations and penalties.
(1)
Any person who violates or permits a violation of this section
shall, upon being found liable therefor in a civil enforcement proceeding
commenced by the Township before a District Justice, pay a fine of
not more than $600, plus all court costs, including reasonable attorney's
fees, incurred by the Township in the enforcement of this section.
No judgment shall be imposed until the date of the determination of
the violation by the District Justice. If the defendant neither pays
nor timely appeals the judgment, the Township may enforce the judgment
pursuant to the applicable Rules of Civil Procedure. Each day a violation
exists shall constitute a separate offense, unless the District Justice,
determining that there has been a violation, further determines that
there was a good-faith basis for the person, partnership or corporation
violating this section to have believed that there was not such violation,
in which event there shall be deemed to have been only one such violation
until the fifth day following the date of the determination of a violation
by the District Justice, and thereafter each day that a violation
continues shall constitute a separate violation. All judgments, costs
and reasonable attorney fees collected for the violation of PRD provisions
shall be paid over to Thornbury Township, Chester County. Further,
the appropriate officers or agents of the Township are hereby authorized
to seek equitable relief, including injunction, to enforce compliance
herewith.
(2)
The Court of Common Pleas, upon petition, may grant an order
of stay, upon cause shown, tolling the per diem judgment pending a
final adjudication of the violation and judgment.
(3)
Nothing contained in this section shall be construed or interpreted
to grant to any person or entity other than Thornbury Township, Chester
County, the right to commence any action for enforcement pursuant
to this section.
