[Added 8-5-2013 by Ord. No. 1626]
A building may be erected and a lot or premises may be used
for any of the following purposes:
A.
Duplex shall require a minimum tract area of not less than four acres
with a lot area of not less than 7,500 square feet for each of the
dwelling units, except as otherwise provided by this article.
B.
Garden apartments, townhouses and other residential apartments may
be developed in a coordinated design on a minimum tract area of not
less than four acres, with not more than one dwelling unit for each
7,500 square feet of lot area except as otherwise provided by this
article.
C.
A development may comprise one or more parcels which are in single
and separate ownership, provided that the development of the parcels
and the uses therein are in accordance with an approved unified development
plan. Development of these parcels and a subsequent conveyance of
a parcel or parcels within the approved plan shall be permitted upon
compliance with the following conditions:
(1)
Irrevocable cross-easements are in effect and recorded in favor
of and duly binding on all title owners within the area of the approved
plan, their successors and assigns, with respect to use, control and
maintenance of the common areas, including but not limited to access
areas, green areas, and parking areas. All easements shall be submitted
to the Township solicitor for review prior to recording, and shall
be recorded before an approved land development plan.
(2)
The application of zoning requirements including, but not limited
to, building coverage, impervious coverage, stormwater management
green area, parking, loading, buffers, setbacks, and landscaping shall
apply to the overall site approved as a unified development plan;
provided, however, parking requirements for a previously approved,
existing, nonconforming use shall be considered as in compliance as
nonconforming.
The density of any multifamily dwelling units developed under
this chapter shall not exceed 21 units per acre and shall comply with
the stormwater management and parking requirements of this article.
In the case of multiple dwelling uses permitted under the M-2
Zoning District, the following specific regulations shall apply in
addition to any other applicable regulation:
A.
General.
(1)
An application for land development of a development of multiple
dwelling uses under this chapter shall be accompanied by a plan which
shall include, among other things, the following information:
(a)
The location, use, design and dimensions of all buildings and
other structures, open spaces, yards, accessory ways, entrances, exits,
off-street parking facilities and buffer strips;
(b)
The character of buffer areas and screening devices which shall
be maintained once a development is complete including the dimension
and arrangement of all areas devoted to planting lawns, trees, or
similar purposes;
(c)
The provisions to be made for the disposal of sanitary sewage,
refuse, and, where deemed necessary by the Board of Commissioners,
appropriate and adequate loading and unloading spaces;
(d)
The site, or portions of the site, shall be developed with coordinated
and preplanned architectural symmetries so as to create "neighborhoods,"
or "groupings" of multifamily dwellings. For example, a development
may proceed with coordinated design that shows landscaped passageways,
similar architectural features on any buildings, and landscaped courtyards
for the use of the residents.
(2)
The tract of land on which each permitted use is conducted or
developed shall be held in single ownership and shall be operated
under unified control or management.
(3)
Landscaping sufficient to buffer adjacent residential neighborhoods
shall be provided.
B.
Parking requirements. Off-street requirements of the Zoning Ordinance
shall be met either by a majority of the parking being located underground,
or in structured parking.
C.
Stormwater management. In addition to any other requirement of the
Zoning Ordinance or the Subdivision and Land Development Ordinance[1] with respect to stormwater management, a majority of the
stormwater facilities necessary for the site may be located underground.
Stormwater management in the M-2 Zoning District for multifamily dwelling
uses shall be applied to the entire property, not just the limits
of disturbance. Any areas of disturbance for new construction shall
comply with all applicable stormwater management requirements. Previously
developed and areas undisturbed for new construction on site shall
be subject to the requirement that stormwater management on the site
shall reduce the peak storm rates by a minimum of 20% from existing
conditions in these previously developed and undisturbed areas. This
twenty-percent reduction shall apply to the one-, two-, five-, ten-,
twenty-five-, fifty- and one-hundred-year storm frequencies. All calculations
shall be based on actual land coverage and shall utilize the SCS design
storm methodology or other methodology acceptable to the Township
Engineer. In the alternative, stormwater management for existing impervious
surfaces located on the site must be considered as "meadow" in the
predevelopment runoff calculations unless other improvements, on site
or off site, are implemented to the satisfaction of the Township and
the Township Engineer.
D.
Phasing. Upon request to the Board of Commissioners at the time of
the land development, construction may be allowed to be phased so
that it is not all completed at the same time; provided, however,
an applicant for phased land development of multifamily dwelling units
shall enter into a written agreement with the Township providing for
the completion of the entire project in accordance with the approved
plans within a period not to exceed three years from the date of issuance
of the first permit or within such other time period as approved by
the Board of Commissioners. Any such phasing shall be accompanied
by appropriate security to ensure completion of all public improvements
on the approved plan, in an amount to be determined by the Township
Engineer.
No building shall exceed 45 feet in height or three stories
in height measured from the mean ground level.
Maximum building area coverage shall not exceed 30% of the lot
area. Maximum impervious surface coverage shall not exceed 70% of
the lot area. Upon approval of the Township Engineer, permanently
installed and maintained roof gardens or rain garden areas may be
acknowledged as a credit against the maximum amount of impervious
surface coverage.
Duplexes, garden apartments and townhouses shall have a front
yard of no less than 20 feet; a rear yard of no less than 50 feet;
and side yards that are not less than 35 feet each.
