Areas of land voluntarily dedicated to and accepted by the Township
or state for a street improvement that would not otherwise be required
by the Township or state and that is not necessary for providing internal
access for the development may be included as buildable area.

Flexibility in Placement. The dwelling units allowed on the
tract may be placed at any appropriate locations within the buildable
area of the tract within the setback and other provisions of this
chapter. However, no single acre of land shall include more than 16
dwelling units, once streets and any common open spaces are deducted
from the lot area.
(4)
In calculating the allowable overall density, land which is
capable of further development or subdivision for additional dwellings
shall not be counted as "buildable area" unless the possibility of
such development or subdivision is precluded by one of the following
methods:
(5)
Condominiums and Lots. The division of land into individual lots is not required, but instead condominium ownership may be used. See § 27-1316.
(6)
Condominium Streets. In any development of or conversion to
condominiums, the Board of Supervisors shall require all streets and
accessways to be constructed or improved to Township standards. The
responsibility of maintaining interior streets and accessways should

safeguards, provisions and arrangements established for funding and
performing such maintenance without involving Township funding or
staff.
E.
Maximum height: 35 feet.

Installation and perpetual maintenance of the buffer yard shall be the responsibility of the developer of the townhouses or garden apartments.
I.
Accessory Uses and Structures.
(1)
See § 27-1403. A ten-foot minimum setback is required for all permitted accessory uses or structures, except a one-and-one-half-foot setback is required along the shared lot line of attached buildings and except where a larger setback is required by § 27-607D, E, F and G or § 27-607M. A twenty-foot-wide minimum setback shall be maintained abutting the future right-of-way of any street.
(2)
To avoid incompatible structures in a higher-density environment,
townhouse developers are strongly encouraged to establish deed restrictions
or homeowner association regulations controlling the general types
and materials of attached decks, fences and accessory structures that
may be added or constructed in the future.
J.
Homeowners' and/or Condominium Agreements. See § 27-1316. It is strongly recommended that any such agreements include restrictions requiring any fencing, decks, garages, or other accessory structures to be compatible with the overall design.
K.
Active Recreation Area.
(1)
For any garden apartment or townhouse development involving
20 or more dwelling units, a minimum of 25% of the tract area shall
be dedicated as common open space.
(3)
For any development that will not be limited to residents 55
years and older, at least 25% of the common open space shall be suitable
for active recreation. "Suitable for active recreation" shall mean
well drained, contiguous, planted in grass, and with average slopes
of less than 4%. For any development involving more than 200 dwelling
units, this area shall include an area graded to less than 4% slope
that is generally suitable for two rectangular fields 300 feet in
length and 100 feet in width.
(4)
For any development limited to persons 55 years and older, the
common open space shall be suitable for passive recreation, with appropriate
landscaping and paths or trails.
(5)
The arrangements and funding for maintenance for recreation
areas shall be acceptable to the Board of Supervisors.
(6)
Land within 15 feet of any building shall not be used to meet
this requirement for common open space.
L.
Maximum building length: 160 feet.
M.
Changes in Facade. For every attached grouping of townhouses, a minimum
of two changes in the front wall plane shall be provided. Such change
shall involve a minimum variation or offset of four feet, and may
be met by placing dwellings so that they are set back further than
attached private garage structures.
N.
Building Setback and Separation.
(1)
Setback. Townhouse and garden apartment buildings and their
permitted accessory structures shall be set back from all exterior
lot lines of a tract and all existing rights-of-way of streets a minimum
setback of 30 feet, except:
(a)
A minimum setback of 70 feet shall be required for principal
and accessory buildings from the lot line of an existing single-family
detached residence. This setback may include any required buffer area.
(b)
A minimum setback of 50 feet shall be required for any principal
building from the future right-of-way of any arterial street.
(c)
A minimum setback of 20 feet for principal and accessory buildings
is permitted from a private street cartway or the future right-of-way
of a local street.
(2)
Separation. Each principal building shall be separated by a
minimum of 20 feet from any other principal building.
O.
Water and Sewer. Public water and public sewer service shall be required
for any townhouse or garden apartment.
P.
Minimum Width of Townhouses. Each townhouse dwelling unit shall have
a minimum width of 20 feet, except that a minimum width of 26 feet
shall be required if the required front yard of the townhouse would
include two or more off-street parking spaces or if garage door(s)
for two or more motor vehicles face onto the front of the townhouse
lot.
Q.
Minimum Private Area.
(1)
For each townhouse, there shall be a yard, balcony, patio or
other outdoor area of not less than 200 square feet other than a driveway
immediately adjacent to the front, back, or side of each dwelling
for the exclusive use of the occupants of that dwelling.
(2)
If townhouses are subdivided into individual lots, the minimum
lot area shall include the building footprint plus these 200 square
feet.
(3)
Design measures shall be used to seek an appropriate level of
privacy in any rear yards. Such measures may include landscaped screening,
compatible fencing, or earthen berming. The intent is to avoid the
placement of incompatible fencing by individual lot owners in the
future.
(4)
Storage. If the maintenance of grass yards in front of or behind
a townhouse could be the responsibility of an individual homeowner,
a storage area suitable for storing lawn maintenance equipment shall
be provided with appropriate outside access, together with the arrangements
to access both the front and back of the townhouse, if necessary.
R.
Private Streets. All private streets and accessways serving more
than five dwelling units, including parking courts, shall be built
to Township construction standards for public streets.
S.
Architectural Renderings. Preliminary architectural renderings, models
or photos shall be submitted to the Township for any garden apartment
or townhouse development of more than 10 units.
T.
Preservation of Natural Buffers. See § 27-1304C(3)(c).
U.
Architectural Variety. A variety of complimentary designs and colors
among clusters of dwellings shall be designed to avoid extreme repetition,
provided that there shall not extreme changes between adjacent facades.
V.
Garages. Townhouses should be designed so that garages and/or carports
are not an overly prominent part of the view from public streets.
For this reason, parking courts, common garage, or carport structures
or garages at the rear of dwellings are encouraged instead of individual
garages opening at the front of the building, especially for narrow
townhouse units.
W.
Mailboxes. Any mailboxes provided within the future street right-of-way
shall be clustered together in an orderly and attractive arrangement
or structure, such as a kiosk, with no dwelling unit more than 300
feet from such a mailbox cluster. Individual freestanding mailboxes
of noncoordinated types at the curbside are specifically discouraged.
X.
Trash Bins. For any garden apartment or rental townhouse development, common receptacles for waste and recycling shall be provided in locations that are convenient for residents and for collection. Screening of such receptacles is required by § 27-1515.
Y.
Access. Vehicular access points onto all arterial and collector streets
shall be minimized to the lowest reasonable number. No townhouse unit
shall have its own driveway entering onto an arterial or collector
street.
Z.
Minimum tract width and depth: 150 feet each.
AA.
Paved Area Setback. All off-street parking spaces, except spaces
on driveways immediately in front of a carport or garage entrance,
