In expansion of the statement of community development objectives contained in Article I, § 165-3, of this chapter, it is hereby declared to be the intent of this article with respect to the R-3B Residential District to establish reasonable standards of performance for a selection of permitted uses therein and to maintain and protect the desirable benefits which medium-density development of single-family detached homes, twin homes and townhouses will have when provided for in selected locations within the Township. It is further the intent of this article to:
A.
Permit a variety of housing types available to present

which will allow the creation of desirable neighborhoods and at the
same time provide adequate protection to existing, established neighborhoods
nearby.
C.
Implement the general recommendation contained in
the Township's Comprehensive Plan to provide areas for medium-density
residential development.
D.
Ensure that the traffic and other impacts of development
in accordance with this district are no greater than can be accommodated
by the infrastructure of the Township.
In an R-3B Residential District, a building
may be erected, altered or used and a lot may be used or occupied
for any of the following purposes and no other; provided, however,
that all other requirements of this article are met:

dwellings per structural unit.

Playgrounds, parks, tot lots and open spaces.
E.
Accessory use on the same lot with and customarily
incidental to any of the foregoing permitted uses.
No principal building shall exceed the height
of 35 feet nor 2 1/2 stories. The maximum height of an accessory
building or structure shall not exceed 14 feet nor one story.
A.
Area of district. A tract area of no less than five
developable acres shall be provided for every area to be used in whole
or part as an R-3B Residential District.
B.
Utilities. All dwelling units within the R-3B Residential
District shall be served by a public sanitary sewage disposal system
and by public water supply. All utility lines (electric, telephone,
etc.) serving the R-3B Residential District developed subsequent to
the enactment of this chapter shall be placed underground.
C.
Density. The development of lots within this district
shall be accomplished in such a manner so as to provide a density
of not more than nine dwelling units per developable acre.
D.
Development plan agreement. The development of a tract
carried out either in a single phase or in stages shall be executed
in accordance with a development agreement based upon a development
plan. The owner, developer and Township shall enter into said agreement
embodying all details regarding compliance with this article to ensure
the binding nature thereof on the overall tract and its development,
which agreement shall be recorded with the final development plan.
F.
Maintenance of common areas and facilities. Provisions
satisfactory to the Board of Supervisors must be made for the perpetual
maintenance and care of all common facilities and open space. Alternatives
include maintenance by the developer or a homeowners' association
or similar entity. Any common open space or recreation area shall
be first offered for dedication, in which event provisions satisfactory
to the Township or similar entity by the developer for active or passive
recreation shall be made. However, the Township need not accept dedication.
G.
Perimeter setback and buffer regulations.
(1)
Building setbacks. No building shall be closer
than 35 feet to the ultimate right-of-way or 40 feet to the perimeter
lines of the tract.

more parking spaces shall be located closer than 15 feet to the ultimate
right-of-way or 40 feet to the perimeter lines of the tract.
(3)
Buffer. The development shall have a permanent
landscaped planting area of at least 15 feet in depth from abutting
property lines designed for screening from view any adjacent uses
to a minimum height of seven feet. The required buffer can be waived
or reduced by the Supervisors, after review and recommendation by
the Planning Commission, if a natural buffer exists or the adjacent
use is compatible.
(4)
Adjoining single-family detached neighborhoods.
When a tract proposed for twin or townhouse dwellings adjoins an existing
single-family detached development of two or more dwellings, or abuts
any of the following districts: AG, RA, R-1A, R-1, R-2 and R-2A, there
shall be provided a one-hundred-foot building setback consisting of
open buffer area or single-family detached dwellings in accordance
with the R-2 District, in which case neither the one-hundred-foot
setback nor the fifteen-foot planted buffer shall be required. For
the purpose of this article, a property shall be considered adjoining
if the tract or parcel has a common lot line or has a common center
line of an existing road right-of-way. The required buffer can be
waived or reduced by the Supervisors, after review and recommendation
by the Planning Commission, if a natural buffer exists, the adjacent
use is compatible or adequate landscape and buffer treatments are
