[Amended 1-21-1992 by Ord. No. 295]
A. The standards and requirements outlined herein shall
be considered minimum standards and requirements for the promotion
of the public health, safety, morals and general welfare.
B. If any mandatory provisions of this chapter are shown
by the applicant to be unreasonable and cause undue hardship as they
apply to his proposed subdivision, the Township Supervisors may grant
a modification to such applicant from such mandatory provisions, so
that substantial justice may be done and the public interest secured;
provided that such variations will not have the effect of nullifying
the intent and purpose of this chapter.
C. In granting modifications, the Township Supervisors
may impose such conditions as will, in their judgment, secure substantially
the objectives of the standards or requirements so varied or modified.
D. When recommended by the Township Engineer and approved
by the Board of Supervisors, a full traffic impact study shall be
required with predevelopment and postdevelopment calculations for
abutting streets and intersections as directed.
[Amended 1-21-1992 by Ord. No. 295]
A. Streets proposed in any major subdivision or land
development shall be in accordance with the Comprehensive Plan and
the Official Map of Upper Southampton Township.
B. The arrangement, character, extent, grade, and location
of proposed streets shall be considered in their relation to existing
and planned streets, to topographical conditions, to public convenience
and safety, and in their appropriate relation to the proposed uses
of the land to be served by such streets.
C. Where such are not in the Upper Southampton Official
Map, the arrangement of streets in a subdivision or land development
shall either provide for the continuation or appropriate projection
of existing principal streets in surrounding areas, or conform to
a plan for the neighborhood approved or adopted by the Board of Supervisors
to meet a particular situation where topographical or other conditions
make continuance or conformance to existing streets impractical.
D. Residential streets shall be so laid out as to discourage
through traffic. However, the design of streets shall provide for
continuation of existing or recorded streets and for proper access
to adjoining undeveloped tracts suitable for future subdivision.
E. Where a subdivision or development abuts or contains
an existing or proposed expressway, arterial or collector street,
the Board of Supervisors with the advice of the Planning Commission
may require either marginal access, reverse frontage with screen planting
along the rear property line, or such other treatment as may be necessary
for adequate protection of properties, to afford separation of through
and local traffic and to reduce the number of access points on major
streets.
F. Streets that are extensions of or obviously in alignment
with existing streets shall bear the names of the existing streets.
Street names shall not be repeated, and all street names shall be
subject to the approval of the Board of Supervisors.
G. If the lots resulting from the original subdivision
are large enough for resubdivision, or if a portion of the tract is
not subdivided, suitable access to street openings for such an eventuality
shall be provided.
H. Dead-end streets shall be prohibited, except as stubs
to permit future street extension into adjoining tracts, or when designed
as culs-de-sac. Stub streets shall be designed with a temporary turnaround
built to the standard required for culs-de-sac.
I. Whenever an applicant proposes to establish a street
which is not offered for dedication and not required to be offered
for dedication, he shall submit a copy of a statement signed by the
Township Solicitor that he has made an agreement on behalf of his
heirs and assigns with the township. Said agreement shall be subject
to the Township Solicitor's approval and shall be recorded with the
subdivision plan. Said agreement shall establish the conditions under
which the streets may later be offered for dedication and stipulate
among other things:
(1) That the street shall be in a good state of repair
as certified by the Township Engineer or that the owners of the lots
along it agree to include with the offer of dedication sufficient
money, as estimated by the Township Engineer, to restore the street
to conform with township specifications.
(2) That an offer to dedicate the street shall be made
only for the street as a whole.
(3) That the method of assessing repair costs shall be
as stipulated.
(4) The agreement to offer the street for dedication by
the owner of 60% of the lots shall be binding on owners of the remaining
lots.
J. Streets shall be carefully related to topography so
as to produce reasonable and minimum grades, satisfactory drainage
and suitable building sites.
K. Private streets may be approved only if they are designed
to meet township street standards for right-of-way, paving width,
drainage, curbs and gutters.
[Amended 1-21-1992 by Ord. No. 295]

along the rear of reverse-frontage lots, an evergreen planting screen
shall be used to provide an adequate visual barrier. The plant material
used shall be of a minimum height of five feet at the time of planting
and shall be planted in a staggered arrangement in order to provide
an immediate effect. Deciduous and semideciduous shrubs may be used
with evergreens to provide accent and color. It is recommended that
a landscape architect be employed to ensure the proper use and arrangement
of plant material and to provide an aesthetically pleasing effect.
The following list is recommended for screening purposes. Buffer trees
must be six feet on center for staggered rows and individual trees
in a row must be 10 feet on center. Approved varieties for use in
buffer strips and shall be limited to the following:
|
Picea Abies - Norway spruce
|
|
Picea Pungens - Colorado spruce
|
|
Picea Pungens Glauca - Colorado blue spruce
|
|
Pinus Nigra - Austrian pine
|
|
Pinus Strobus - White pine
|
|
Tsuga Canadensis - Canadian hemlock
|
|
Thuja Nigra - Dark American arborvitae (for use in narrow areas;
straight line spacing three feet on center)
|
K. Trees and other required plant material shall not be planted until
the finished grading of the subdivision or land development has been
completed.
L. All trees having a diameter of 20 inches or greater measured at a
distance of four feet above ground level on land proposed for development
are subject to regulation and shall be shown on the preliminary and
final plans. The cutting or removal of a tree subject to regulation
shall take place only by written approval of the Township.
M. All trees subject to regulations shall be located on the preliminary
and final plans including trees proposed for removal and for retention,
and trees likely to be affected by proposed grading. The plan shall
indicate the nature of the protection to be provided to retain the
original grade level within the drip line of the tree in the latter
case.
N. For each tree with a diameter of 20 inches or greater that is removed,
a replacement tree of a size not less than that provided in this section
shall be provided by the developer when such replacement is feasible
and desirable in the opinion of the Township. The replacement tree(s)
locations and species shall be indicated on the preliminary and final
plans.
O. All materials, installation and maintenance provisions shall be in
accordance with the American Association of Nurserymen.
[Amended 1-21-1992 by Ord. No. 295]
A. Conformance to Zoning Ordinance regulations. The density, parking area and building requirements shall in all respects conform to Chapter
185, Zoning, for multifamily developments.
B. Filing of plans for preliminary and final approval.
Preliminary approval of the site plan must be obtained for the entire
proposed multifamily development. Final approval may be obtained section

[Amended 1-21-1992 by Ord. No. 295]
A. The subdivision of a portion of a lot for commercial
purposes shall be accompanied by a site development plan showing the
intended development of the entire tract.
B. Additional width of streets adjacent to areas proposed
for nonresidential use may be required as deemed necessary by the
Board of Supervisors to assure the free flow of through traffic from
vehicles entering or leaving parking areas. For developments fronting
on an existing or proposed expressway, arterial or collector street,
the Board of Supervisors may require marginal access to provide separation
from through and local traffic.
C. When adjacent lots proposed for nonresidential uses
front on a collector or arterial street, the owner may be required
to provide a service road for ingress and egress, or in lieu thereof,
the owner may be required to provide an area adjacent to the proposed
lots for off-street parking purposes.
D. Adjacent residential areas shall be protected from
potential nuisance of the proposed nonresidential developments, including
the provision of extra depths in parcels backing up on existing or
potential residential developments and provisions for a permanently
landscaped, evergreen buffer strip.
E. Streets carrying nonresidential traffic shall not
normally be extended to the boundaries of the adjacent existing or
potential residential areas, nor connected to streets intended for
predominantly residential traffic.
F. Parking areas shall be located or designed in such
a manner that they are visibly secluded from eye level of the surrounding
area. Grading to depress the parking area, raised berms, landscaping,
or fencing are satisfactory methods to create such seclusion.
G. All area, design, and parking requirements shall conform to Chapter
185, Zoning.
[Amended 6-20-1989 by Ord. No. 268]
A. General requirements.
(1) Grade changes and excavations shall not encroach upon
the tree protection zone.
(2) The area within the TPZ shall not be built upon, nor
shall any materials be stored there either temporarily or permanently.
Vehicles and equipment shall not be parked in the TPZ.
(3) When tree stumps are located within 10 feet of the
tree protection zone the stumps shall be removed by means of a stump
grinder to minimize the effect on surrounding root systems.
(4) Tree roots which must be severed shall be cut by a
backhoe or similar equipment aligned radially to the tree. This method
reduces the lateral movement of the roots during excavation, which
if done by other methods could damage the intertwined roots of adjacent
trees.
(5) Within four hours of any severance of roots, all tree
roots that have been exposed and/or damaged shall be trimmed cleanly
and covered temporarily with peat moss, moist burlap or other moist
biodegradable material to keep them from drying out until permanent
cover can be installed.
(6) Sediment, retention and detention basins shall not
discharge into the tree protection site.
(7) Sediment, retention and detention basins shall not
be located within the tree protection zone.
B. The tree protection zone requirements.
(1) Prior to construction, the tree protection zone shall
be delineated by the following methods:
(a)
The tree protection zone that is delineated
on the site prior to construction shall conform to the approved development
plans.
(b)
All trees scheduled to remain shall be marked;
where groups of trees exist, only the trees on the edge need to be
marked.
(2) A forty-eight-inch-high fence mounted on steel posts,
located eight feet on center, shall be placed along the boundary of
the tree protection zone; when the fence has been installed, it shall
be inspected and approved by the Municipal Arborist prior to commencing
clearing and further construction; the fencing along the tree protection
zone shall be maintained until all work/construction has been completed;
and damages to the protective fencing shall be placed and repaired
before further construction shall begin.
(3) In addition to the tree protection zone, trees may
be left standing as protection between the trunks of the trees to
be retained and the limits of grading. When additional trees are used
as protection, the tree protection zone on the approved plan shall
be marked in the field so that the additional buffer area is delineated.
When this method of protection is used, these additional trees shall
be removed at the time of completion of the project.
(4) Trees being removed shall not be felled, pushed or
pulled into a tree protection zone or into trees that are retained.
C. Retaining walls.
(1) When the original grade can not be retained at the
tree protection zone line, a retaining wall shall be constructed outside
of the tree protection zone; the retaining wall shall be designed
to comply with the township standards for retaining walls.
(2) In addition to the above, the following methods shall
be used to ensure survival of the tree:
(a)
The top of the wall shall be four inches above
the finish grade line.
(b)
The wall shall be constructed of large stones,
brick, building tile, concrete blocks or treated wood beams not less
than six inches by six inches; a means for drainage through the wall
shall be provided so water will not accumulate on either side of the
wall; weep holes shall be required with any wall.
(c)
Any severed roots as a result of excavation
shall be trimmed so that their edges are smooth and are cut back to
a lateral root if exposed.
(d)
A layer of clean stone (sized 3/4 inch to one
inch) shall be placed one foot out from the wall to aid in drainage.
D. Pruning methods. All final cuts shall be made sufficiently
close to the trunk or parent limb but without cutting into the branch
collar or leaving a protruding stub, according to the National Arborist
Association standards. All necessary pruning cuts must be made to
prevent bark from being torn from the tree and to facilitate rapid
healing. Flush cuts are unacceptable.
E. Fertilization methods.
(1) All trees which have experienced any disturbance or
have had damages to the roots or branches shall be fertilized.
(2) Trees shall be fertilized in early fall (September-October)
or mid-spring (April-May). Fall applications are preferred.
(3) Fertilizer shall be broadcast over the soil surface in an area twice the size of the tree protection zone at the rates given in Subsection
E(5) below. A minimum of 1,000 square feet per tree will receive fertilization.
(4) Fertilizer grade shall have approximately three parts
nitrogen to one parts phosphorus and potassium (3 to 1 to 1 ratio).
(5) Fertilizer shall be applied at a rate equivalent to
one pound nitrogen per 1,000 square feet.

F. Trenching and tunneling.
(1) If there is no alternative but to locate a utility
line through a TPZ, tunneling shall be used instead of trenching,
except where, in the opinion of the Municipal Arborist, survival of
the tree would not be affected by either method. The Municipal Arborist
shall recommend the most desirable location for the utility line.
(2) Trenches shall be filled as soon as possible, and
tamped lightly to avoid air spaces.
