The Unified Development Area (UDA) District is established for
the following purposes:
A.
To provide an opportunity for integrated development of a variety
of uses according to a master development plan ("master development
plan");
B.
To encourage the preservation of greenway land for conservation and
low- to medium-intensity recreation;
C.
To provide opportunities for site design that conserve the natural, historical and visual resources of the tract [as defined in § 390-114B(1) below];
D.
To provide opportunities for stormwater and wastewater management
facilities which promote groundwater recharge;
E.
To provide flexibility in design and use of larger tracts of land
within the Township consistent with the goals and objectives of the
Township Comprehensive Plan and the County Comprehensive Plan ("Landscapes
2"); and
F.
To provide an opportunity for unified and harmonious development
in order to establish continuity between uses in terms of character,
scale, building massing, internal circulation patterns and greenway
land, all of which shall be designed to prevent sprawl by concentrating
the development of the tract so as to minimize (to the maximum extent
possible) a development's visual and environmental impacts on the
Township and surrounding community and to limit the necessary infrastructure
within a development.
A.
The UDA District of the Township shall be as shown on 390 Attachment 10:9 of the West Vincent Code as adopted on May 27, 1999 (the "UDA Overlay"). All existing and future uses within the UDA Overlay shall be subject to all other applicable provisions of Article XIX of the Township Zoning Ordinance.
[Amended 3-20-2023 by Ord. No. 204]
B.
In order to be eligible for conditional use approval of a master
development plan pursuant to this section, all of the following eligibility
criteria shall be met:
(1)
The property on which the UDA District and the master development
plan is proposed shall be a minimum of 200 acres, which shall be under
the legal or equitable ownership of the applicant ("master development
plan tract").
(2)
The master development plan tract shall have frontage along
a collector or arterial road as designated by the Township Comprehensive
Plan.
(3)
If the master development plan tract is not held in single ownership,
all of the owners of the tract must join in the application.
(4)
The master development plan tract shall be composed of a combination
of residential- and nonresidential-based zoning uses, developed as
either:
(a)
Primary residential UDA development. A primary residential UDA
development shall be defined as a UDA development where 75% or greater
of the developable UDA tract acreage (as defined and calculated below)
is utilized for residential uses (as set forth below), with the balance
of the developable UDA tract acreage to be utilized as an office park
use or a farmstead use.
(b)
Primary nonresidential UDA development. A primary nonresidential
UDA development shall be a UDA development where less than 75% of
the developable UDA tract acreage (as defined and calculated below)
is utilized for residential uses, with the balance of the developable
UDA tract acreage to be utilized as an office park or a farmstead
use.
(5)
The applicant shall demonstrate compliance with all provisions
of this article.
(6)
The applicant shall delineate on the master development plans all areas of developable UDA tract acreage, as well as shall set forth its calculation of the density attributable to each. It shall be noted that neither the percentage limitations set forth in Subsection B(4) above nor the underlying zoning district designation shall serve as a limitation on the siting of any residential uses, office park uses and/or farmstead uses; provided, however, that the density shall not be modified or adjusted based upon the siting of such uses.
A.
Conditional use approval shall be required of the master development
plan. There shall be permitted, upon conditional use approval by the
Board of Supervisors of an application for a master development plan
("master development plan"), one or more of the following uses:
(1)
Residential uses, including but not limited to single-family detached, single-family semidetached, multiple-family, single-family garden lot development and attached garden lots as described in § 390-116 and subject to the standards therein;
(4)
Any use permitted by the existing underlying zoning district
to which the tract is subject.
C.
In addition to an applicant's obligation to demonstrate through the
conditional use process those requirements set forth throughout this
article, an applicant must demonstrate that a master development plan
satisfies all of the following criteria:
(1)
Development pursuant to the master development plan shall be in accordance with the zoning regulations established in §§ 390-116, 390-117 and 390-118 and, to the extent not expressly addressed herein, with the regulations in the underlying zoning districts, provided that the master development plan conditional use approval shall be in lieu of any other requirement for a special exception or other form of use approval otherwise required in an underlying zoning district.
(2)
Greenway land. The amount of greenway land required for a UDA
development is dependent on whether the applicant proposes a primary
residential UDA development or a primary nonresidential UDA development.
With respect to a primary residential UDA development, not less than
60% of the adjusted tract acreage shall be designated and preserved
as greenway land. With respect to a primary nonresidential UDA development
that provide at least 25% of the developable UDA tract acreage as
farmstead use, not less than 60% of the adjusted tract acreage shall
be designated and preserved as greenway land. With respect to a primary
nonresidential UDA development that provides less than 25% of the
developable UDA tract acreage as farmstead use, no less than 80% of
the adjusted tract acreage shall be designated and preserved as greenway
land. Irrespective of the form of development sought by the applicant,
the greenway land shall be designed to link proposed neighborhoods,
conserve sensitive environmental and cultural resources (with consideration
being given to contiguous wildlife migration corridors) and provide
opportunity for low- and medium-intensity recreation. The greenway
land shall be dedicated or conveyed to the Township or retained in
private ownership for agricultural uses (being permanently restricted
by easement or restrictive covenant agreement). The greenway land
requirement in this article shall supersede and be in lieu of all
other Township ordinances requiring the designation of greenway land
or community facilities (except as incorporated herein).
(3)
The layout and distribution of greenway land shall, to the maximum extent practicable, conserve the features identified in the Township's Greenway Land Stewardship Guide and the Township's Open Space and Recreation Plan (such as scenic viewsheds from existing public roads) and to achieve the goals of the Township's Sustainability Plan. In addition, the greenway land shall be in conformity with the Township's objective of conserving an interconnected network of greenway land and shall be in conformity with the purposes set forth in § 390-113.
(4)
In order to promote unified and harmonious development and to
further establish continuity between areas of the UDA designated for
residential use, farmstead use and/or office park use, all proposed
buildings and structures (with the exception of existing or proposed
farmstead use buildings or structures) shall conform to the following
minimum architectural guidelines:
(a)
All facades shall be of wood, brick, stone, stucco, split and/or
smooth face concrete block, vinyl or composite siding, or a combination
thereof. The front facades shall be articulated by the use of color,
materials (i.e., stone to stucco, masonry patterns, etc.), and roofline
(eaves, gables and mansards, etc.).
(b)
Roof material may be wood or asphalt shingles, slate, composite
slate or concrete tile. Metal roofing (standing seam-type) is acceptable
so long as its color is consistent with the overall palette.
(c)
All rooftop mechanical equipment shall be screened by materials
architecturally compatible with the building.
(d)
At the time of preliminary subdivision and land development
plan submission, the applicant shall submit, and the Township shall
review, the preliminary/conceptual architectural drawings (with materials)
demonstrating compliance with these architectural guidelines.
E.
Once the master development plan is approved, permits may be issued
only pursuant to approved land development and/or subdivision plans
consistent with the approved master development plan.
F.
The master development plan tract may be subdivided for separate ownership or lease (or as otherwise required by the Municipalities Planning Code or Chapter 315, Subdivision and Land Development, of the Township's Code), but only if the subdivision does not interfere with the development or use of the master development plan tract in accordance with the approved master development plan.
G.
Calculation of the developable UDA tract acreage. The developable
UDA tract acreage shall be calculated as follows:
(1)
Primary residential UDA development.
(a)
Determine the total tract acreage.
(b)
Calculate the adjusted tract acreage (per the definition thereof included in § 390-8 of this chapter by subtracting the weighted percentages of environmentally sensitive areas, existing rights-of-way and existing easements from the total tract acreage).
(c)
Subtract the required minimum greenway land required in this
article (being 60% of the adjusted tract acreage) from the adjusted
tract acreage.
(d)
The result of this calculation is the "developable UDA tract
acreage."
(2)
Primary nonresidential UDA development.
(a)
Determine the total tract acreage.
(b)
Calculate the adjusted tract acreage (per the definition thereof included in § 390-8 of this chapter, by subtracting the weighted percentages of environmentally sensitive areas, existing rights-of-way and existing easements from the total tract acreage).
(c)
Subtract the minimum greenway land required in this article
(being 80% of the adjusted tract acreage) from the adjusted tract
acreage.
(d)
The result of this calculation is the "developable UDA tract
acreage."
H.
Condominium ownership. If all or a portion of the master development
plan tract is to be owned in a condominium form of ownership, the
applicant shall designate for each condominium unit and/or building
housing multiple condominium units a designated area contiguous to
such units equivalent to the required minimum lot width, minimum lot
area, minimum side yard, minimum rear yard, minimum front yard, minimum
parking area setback, maximum impervious coverage, maximum lot coverage
and maximum building coverage, as if the same were subdivided into
separate lots. Such designated area shall not overlap the designated
area for such area and bulk limitations of another condominium unit.
I.
Environmental. All new residential buildings in a UDA development
shall be certified as "LEED housing," and all new nonresidential buildings
shall be certified as "LEED construction." An applicant may deviate
from this requirement upon approval from the Township Board of Supervisors,
in its discretion, if either the LEED certifications referenced above
shall no longer be available or should the applicant be able to establish
that it will comply with equivalent or greater standards.
J.
Impervious coverage. A maximum of 50% of the developable UDA tract
acreage shall be permitted as impervious coverage.
The following residential uses may be approved by the Board
of Supervisors as a component of a master development plan in the
UDA Overlay District, subject to the following conditions and other
conditions as warranted to secure the purposes of this article and
the public health, safety and welfare:
A.
Area. The minimum area of the master development plan devoted to residential uses shall be as set forth in § 390-114B(4) above.
B.

of this article, the applicant shall have the discretion to select
one of the following density options to be applicable to the proposed
UDA development:
(1)
Option 1 (primary residential UDA development with farmstead
use; primary nonresidential development with farmstead use). If the
developable UDA tract acreage is developed as 75% or less residential
use, with the remainder of the UDA tract acreage to be utilized for
farmstead use, the permitted residential density shall be 1.40 dwelling
units per acre of developable UDA tract acreage. If the applicant
dedicates a minimum of 50% of the greenway land to the Township, then
the permitted residential density shall be 1.50 dwelling units per
acre of developable UDA tract acreage.
(2)
Option 2 (primary residential UDA development with office park/farmstead
uses). If the developable UDA tract acreage is developed as 75% residential
use, with the balance of the developable UDA tract acreage being a
combination of office park uses and/or farmstead uses, then the permitted
residential density shall be 1.00 dwelling unit per acre of developable
UDA tract acreage. If the developable UDA tract acreage is developed
as greater than 75% residential use, with the balance of the developable
UDA tract acreage being office park uses or a combination of office
park uses and/or farmstead uses, then the permitted residential density
shall be 0.75 dwelling units per acre of developable UDA tract acreage.
Irrespective of the percentage of residential use provided under this
subsection, the applicant shall be permitted an additional 0.01 dwelling
units per acre of developable UDA tract acreage for every 1% of developable
UDA tract acreage devoted to farmstead use; provided, however, that
in no event shall such density bonus result in a density of greater
than 1.25 dwelling units per acre of developable UDA tract acreage.
(3)
Option 3 (primary nonresidential UDA development with office
park/farmstead uses). If the developable UDA tract acreage is developed
as less than 75% residential use, with the balance of the developable
UDA tract acreage being a combination of office park and/or farmstead
uses, then the permitted residential density shall be 0.60 dwelling

Such golf courses shall comply with all requirements of § 390-175 of this chapter, and the entirety of a golf course area shall be placed under a conservation easement (to which the Township shall be a third party beneficiary or party), subject to the approval of the Township Board of Supervisors, restricting the same against further land development or further subdivision.
A portion of the master development plan tract, constituting
a minimum of 30% of the adjusted tract acreage, shall be designated
as a farmstead agricultural operation. This minimum required farmstead
use may be reduced only upon waiver by the Township Board of Supervisors,
in its discretion. Only passive agricultural operations uses shall
be permitted on a farmstead, excepting that tree nurseries and sod
farms shall not be permitted. The farmstead shall be subject to a
declaration of restrictive covenants, to which the Township shall
be a party, which shall limit the uses of the farmstead in perpetuity
to agricultural or forestry uses (provided that this covenant shall
not require active agricultural or forestry uses of the farmstead
and provided that such shall be subject to the timber harvesting provisions
of this chapter), not to be further subdivided or developed except
for: (i) agricultural accessory buildings and/or farm buildings and
one single-family residence as the main house and not more than one
additional residence as a farmstead tenant house; or (ii) sewage facilities.
The declaration shall be recorded in the Chester County Recorder of
Deeds office.
A.
The farmstead, as so restricted, shall qualify as greenway land in meeting the minimum greenway land requirements of § 390-115. If the farmstead has already been conserved or restricted from further development prior to submission of a conditional use application under this article, the conserved or restricted area shall not be counted toward the minimum required greenway land.
B.
The maximum total building coverage permitted on an area of a property
designated for a farmstead use shall be 1.5% of the area designated
and delineated for farmstead use, and the total impervious coverage
shall be a maximum of 2.5% of the area designated and delineated for
farmstead use (excluding access driveways, public sidewalks and paved,
public trails).
Applications for adoption of a UDA and approval of the master
development plan shall meet all procedural requirements for conditional
use approval as required by the Municipalities Planning Code and this
chapter, and shall include the submission of a master development
plan and accompanying support data for the master development plan
tract, as follows:
A.
Master development plan. The master development plan is a conceptual,
feasibility analysis of the manner in which the UDA ordinance will
be implemented on the master development plan tract. The base site
plan for the master development plan shall be drawn at a scale of
not less than one inch equals 200 feet and shall contain information
sufficient to assess the impact of future development of the tract,
including, but not limited to, the following:
(1)
The boundaries of each of the subdistricts within the entire
tract, including, but not limited to:
(2)
The general vehicular and nonvehicular circulation pattern for
the entire tract, including points of access to the tract, and the
location, dimensions and rights-of-way of the major road network that
will link subdistricts.
(3)
The source of and general methods by which water shall be supplied
and sewage shall be treated and disposed.
B.
Natural features analysis. In order to determine which specific areas
of the tract are suitable for development and which areas should be
preserved in their natural state, an analysis of natural features
shall be required. The following considerations must be included in
the analysis and site planning responsive to these findings:
(1)
Topography. An analysis of the terrain of the tract before construction,
including mapping of elevation and delineation of slope areas according
to the following categories: 0% to 8%, 8% to 15%, 15% to 25%, and
over 25% slope.
(2)
Drainage. An analysis of natural drainage patterns and water
resources, including streams, natural drainage swales, ponds or lakes,
woodlands and marsh areas, floodplain areas, permanent and seasonal
high-water table areas shall be included. Natural drainage features,
