1.
The purpose of the landscaping regulations contained in this Part
is to enhance health and safety, as well as the quality of life, in
the Township. As such, these regulations are designed to promote practical
and attractive development within the Township; to provide for screening
and buffering; to preserve, protect, and utilize native vegetation,
to enhance property value; to promote wildlife habitat; to aid in
the reduction of noise, heat, and glare; to conserve energy; to minimize
erosion and sedimentation; and to establish a healthier environment.
Landscaping shall be conceived in a total pattern throughout the site,
integrating the various elements of the site design, preserving and
enhancing the particular identity of the site, and creating an inviting
site character. Consideration shall also be given to the compatibility
with and enhancement of adjacent or off-site landscaping conditions.
2.
Landscaping may include plant materials, such as trees, shrubs, ground
covers, perennials, and annuals; natural materials, such as rocks
and water; and man-made materials, such as sculpture, art, walls,
fences, paving materials, and street furniture.
[Ord. No. 2023-07, 11/1/2023]
1.
In general, all land areas within a subdivision or development not
containing buildings or structures or imperious surfaces, or other
improvements which preclude landscaping, shall be included in a landscape
plan.
2.
A landscape plan shall be required for each major subdivision plan
and for each nonresidential land development, other than agricultural.
This would include multifamily residential land development. The plan
shall be submitted in conjunction with the preliminary subdivision
and land development plan submission. The regulations shall not be
construed to regulate individual lots for single-family and semidetached
residential dwellings, except for street trees and all areas held
in common ownership, stormwater management facilities, buffer areas,
rights-of-way, and easements.
[Ord. No. 2023-07, 11/1/2023]

[Ord. No. 2023-07, 11/1/2023]
1.
Every effort shall be made to preserve mature trees, other significant
existing vegetation and natural features on a development site and
to incorporate these existing natural features into an overall planting
design. Every effort shall be made to retain as much of a wooded area
as possible of a size and configuration that will promote its natural
growth and regeneration particularly when adjoining adjacent woodlands.
2.
No street trees shall be required where streets are bordered by permanent
woodlands.
[Ord. No. 2023-07, 11/1/2023]
1.
Every effort shall be made to reduce the loss or damage to trees
existing on site which are to remain. A tree shall be considered preserved
if there is no disturbance within the tree's critical root zone.
"Disturbance" includes earth disturbance, earth compaction, vehicular
and foot traffic, material stockpiling, and/or the construction of
all proposed improvements and utilities.
2.
The critical root zone extends from the tree trunk a distance equal
to 12 times the trunk diameter, or to the tree's dripline plus
five feet, whichever distance is greater.
3.
A tree shall be considered preserved if the Township's landscape
professional determines it is in viable condition at the end of the
guarantee period.
4.
The following conservation practices are mandatory and shall be noted
on the soil erosion and sedimentation control plan and employed in
order to preserve existing trees. In addition to the other requirements
specified in this section, these conservation practices shall be undertaken
during land development activities. Prior to any clearing or site
disturbance, the Township requires a meeting with the applicant and/or
site contractor to further determine methods to minimize tree loss.
For this meeting, the Township shall appoint a qualified landscape
professional to act on its behalf.
A.
All trees, natural features, and other vegetation to be preserved
shall be protected from equipment damage by snow fencing or other
effective barriers approved by the Township. Fencing or barriers around
trees shall be placed outside the dripline, unless approved by the
Township to be appropriate at another location. Tree protection installation
must be approved by the Township's landscape professional prior
to the start of any clearing, grading, or other earth disturbance
and monitored periodically. The tree protection fencing shall be maintained
by the applicant while in place. It shall be removed after all earthmoving
and construction activities that may impact tree roots are completed.
B.
When disturbance within the critical root zone is unavoidable, applicants
shall minimize encroachment and use the best available methods as
approved by the Township's landscape professional to minimize
damage and preserve trees. These methods may include utility tunneling,
use of geotextiles, mulching, hand root pruning, and soil aeration.
Applicants shall consult references such as "A Guide to Preserving
Trees in Development Projects," published by the Penn State College
of Agricultural Sciences Cooperative Extension.
C.
Should any mature, viable trees on the site not scheduled to be removed
be irreparably damaged during site preparation activities and, as
a consequence thereof, die or decline, as determined by the Township
landscape professional, within 18 months of the conclusion of construction
activities, such trees shall be replaced with nursery- grown material
in accordance with the following requirements:
(1)
For deciduous trees of six inches' up to 12 inches'
DBH, one inch of new tree caliper shall be provided for every six
inches of existing tree diameter cut or removed.

street, the trees are similar as regards to height and spread and
that similar species are planted within single- or two-family detached
lots.
(9)
Trees shall be planted so as not to interfere with the installation
and maintenance of sidewalks, lights and utilities. Trees shall be
set back 10 feet from underground utilities; tree canopies or crowns
at maturity shall be at least 15 feet from overhead utilities.
(10)
Groves or clusters or other arrangements of street trees may
be permitted where conditions warrant, subject to the approval of
Shrewsbury Township.
[Ord. No. 2023-07, 11/1/2023]
1.
Buffers and screens shall be used to minimize or eliminate views
of development and site elements and to provide landscaping that will
soften and mitigate views between the development and its surroundings
and provide opportunities for green links between properties.
2.

5.
Perimeter Buffer Requirements.
A.
Perimeter buffers shall be planted along or adjacent to all arterial
and collector streets. Such buffers shall be no less than 35 feet
in width as measured from the street's right-of-way (ROW). In
instances where major developments occur along streets classified
local, perimeter buffers may be required depending on traffic volumes,
the overall intensity of the proposed development(s) and the nature
of adjacent or nearby uses as determined by Shrewsbury Township.
B.
A ten-foot landscaped perimeter buffer shall be placed separating
adjacent developments or subdivisions within the same zoning district.
C.
Perimeter buffers shall comply with Buffer Planting Strip B, C or
D as determined by the intensity and potential conflicting nature
of adjoining uses. Shrewsbury Township must concur with the planting
strip selected.
D.
Perimeter buffers shall be placed at the property or right-of-way
line.
6.
Building Site Element Screens. Site element screens shall be placed
to screen electrical, mechanical and utility equipment; loading and
storage areas not enclosed in a building; trash disposal sites; as
well as other structures and areas associated with various principal
uses or principal uses themselves as determined by Shrewsbury Township.
Screening is required when such elements are proposed within 200 feet
of a property or right-of-way line. Site element screens may be located
within required buffer areas. Site element screens may be eliminated
if they are adjacent to or within screen buffers, provided the screen
buffer effectively screens views of the site element. Site element
screen plantings shall be designed in such a fashion so as to not
draw attention to the element itself.
A.
Site element screens shall be one of the following types, according
to use. If a use is not listed, the screen most suited to the use
shall be used.
(1)
Low screens shall be used around the perimeters of all parking
lots or other similar vehicular use areas, including service stations,
sales lots for motorized vehicles, vehicular stacking lanes associated
with a drive-through, and around trash enclosures or storage buildings
when decorative walls, such as brick, latticework or split-face concrete
block, are proposed.
(2)
High screens shall be used adjacent to loading areas, around trash enclosures and storage buildings when fencing or plain concrete masonry units are proposed, and around transformers, maintaining the required clear distance. High screens or opaque fencing at least six feet in height shall also be required to buffer accessory structures from the higher-classification street on reverse-frontage lots. All fencing shall be installed in compliance with § 27-1507 of the Township's Zoning Ordinance.
(3)
Yard screens shall be placed around vehicular storage areas
that are not used as parking lots or sales areas, around the perimeter
of tank farms and similar facilities, and around utility towers and
equipment yards.
B.
Site element screens shall be measured at the base of the element
being screened. This might be the base of a trash enclosure or the
surface of a parking lot closest to the screen.
C.
Low screens shall conform to the following:
(1)
They shall be comprised of evergreen or dense deciduous shrubs
to form a continuous screen or hedge, which shall reach a minimum
height of three feet after two years of growth. For example, if a
parking lot elevation is higher than the adjacent street and the screen
plantings are placed at a lower elevation on the slope between the
two, then the screen must consist of either larger plants or a taller
species or be maintained higher to provide a three-foot-high screen
as measured from the surface of the parking lot. Conversely, if a
berm is used in conjunction with screen plantings, they may be shorter
plants, as long as an effective screen is provided.
(2)
Small shrubs shall be spaced no farther than three feet on center.
Large shrubs shall be spaced no farther than six feet on center.
E.
Yard screens shall conform to the following. They shall be of the
same composition as high screens, except that, in addition, large
shrubs shall be planted on five-foot centers alongside the evergreen
trees.
7.
Individual Building Site Landscaping Requirements.
A.
Landscaping shall be an appropriate scale relative to the proposed
adjacent structures.
B.
Landscaping shall be provided at building entrances.
C.
A minimum planting width of six feet adjacent to the building and
no less than 25% of the building perimeter shall be planted with multistemmed
ornamental trees, shrubs, perennial flowers, and ground cover. Emphasis
should be given to landscaping along the front building elevation.
D.
Additional landscaping shall be provided around the perimeter of
buildings to soften the edge between sidewalk/parking lots and structures.
E.
Landscaping shall be protected from vehicular and pedestrian encroachments
with raised planting surfaces, depressed walks, and/or curbs.
8.
Entrance Landscaping and Signage Requirements. All major subdivisions
and developments, as well as minor residential subdivisions on private
or public subdivision roads, shall meet the following requirements:

An earth-tone sign consisting of natural materials with the name
of the subdivision/development shall be located at the entrance(s)
and suitably sized so that it is easily read by the passing public.
B.
Landscaping shall be integrated with the entry sign so as to provide
an attractive complementary natural setting.
C.
It is suggested that three levels of scale or height utilizing shade,
evergreen, and/or ornamental trees, shrubs, annuals, and perennial
flowers and ground cover be included in the design.
D.
All signs shall be consistent with Shrewsbury Township Sign Ordinance
requirements.
9.
Plants shall be distributed throughout the entire length of the buffer
or screen as follows:
A.
Plantings in site element screens shall be evenly spaced to create
a continuous visual screen.
B.
Plantings in buffers need not be evenly spaced but should be positioned
to provide an effective screen of the development.
C.
Plantings in buffers may be clustered.
D.
Plants which exhibit one or more of the following characteristics
should be avoided:
(1)
Plants that will become a nuisance to neighboring properties
or that will threaten the ecological balance of adjacent woodlands
and natural areas because they are aggressive and invasive. Aggressive
and invasive plants shall include, but not be limited to: exotic bamboos,
purple loosestrife, butterfly bush, white mulberry, and kudzu.
(2)
Plants which spread by rhizomes or stolons, unless an approved
method of root containment is utilized.
(3)

and/or diseases, which may shorten their life expectancy and ability
to provide an effective buffer.
E.
The remainder of the buffer or screen area shall be planted with
ground covers, including lawn grasses or meadow plantings, as appropriate
to the character of the site and adjacent lands.
F.
Buffer and screen planting areas shall be mulched with a material
appropriate to the site's character. Beds are encouraged for
ease in maintenance. Individual mulched areas may be joined as plants
mature and maintenance practices change.
[Ord. No. 2023-07, 11/1/2023]
1.
All parking lots with 10 or more spaces shall be designed and effectively
landscaped with trees and shrubs to:
A.
Provide shade in order to reduce the amount of reflected heat and
to improve the aesthetics of parking lots.

shall be located at the end of each parking space row and at intervals
of no greater than 100 feet apart, or every 10 parking stalls, in
single or double bays.
B.
Islands should be placed opposite each other in adjacent rows of
parking, to reduce the number of islands and to increase the area
available for tree roots.
C.
The last parking stall in a row shall be separated from drive aisles
by a planting island a minimum of 10 feet in width.
D.
Each planting island shall contain one shade tree plus shrubs, ground
cover, perennials and/or mulch to cover the entire area at maturity.
Fifty percent of all street trees, shade trees and evergreen trees

B. Shrubs shall not exceed two feet in height.
3.
Divider strips shall conform to the following standards:
A.
Divider strips shall be placed at every other bay of parking running
the length of the rows of parking and landscaped with plantings of
shade, ornamental and/or flowering trees, plus shrubs, ground cover
and/or mulch to cover the entire area at maturity. A bay of parking
is the width of pavement needed to accommodate either one or two rows
of parking stalls plus one access lane.
B.
Divider strips shall be a minimum of 10 feet wide, unless a sidewalk
is proposed within the divider strip. If a sidewalk is proposed within
the strip, the sidewalk may be placed in the center of the strip or
to one side. The divider strip shall be increased in width by six
feet to accommodate the sidewalk.
(1)
One shade tree shall be required for each 30 feet of divider
strip. Two ornamental and/or flowering trees may be substituted for
each shade tree. The trees need not be spaced evenly apart; however,
the maximum spacing shall be 50 feet.
(2)
One large shrub or two small shrubs shall be required for each 10 feet of divider strip. Shrubs shall be spaced according to the guidelines in § 12-105, Subsection 1E of this Part. Gaps may be placed between the shrub plantings to provide areas for ground covers, decorative mulch beds, artwork, crosswalks or flowering plants. Shrubs near the ends of divider islands shall not exceed two feet in height so as not to block visibility. This shall not preclude the use of taller shrubs elsewhere within the divider island.
4.
Plantings shall be placed between parking lots and buildings to break
up long stretches of facade and provide a more-comfortable pedestrian
environment, according to the following standards:
A.
Plantings are required for all sides of a building facing parking areas. Plantings are not required along the sides of buildings containing service or loading areas. If part of a side of the building faces parking, only that portion is subject to these requirements. Loading areas must be appropriately screened according to the requirements of § 12-110, Subsection 2A(2) of this Part. Loading area screening is in addition to the requirements of this section.
B.
The minimum planting requirement shall be one shade tree per 50 feet
of building facade plus five small shrubs per 20 feet of building
facade.
C.
Any plantings in addition to the requirements of this section may
be placed in a lawn area, tree pits, planters or hanging baskets as
appropriate to the character of the development, using the following
guidelines as to placement:
(1)
Deciduous trees, ground covers and perennials may be placed
anywhere between the curb and the building or outdoor areas.
(2)
If any tree is located closer than 10 feet to a sidewalk, approved
root barriers shall be placed along the tree side of the sidewalk
for a distance of 12 feet, centered on the trunk.
(3)
Planters shall be at least 30 inches high but no higher than
42 inches and contain drainage holes.
(4)
The bottoms of hanging baskets shall be at least eight feet
above the sidewalk surface to provide for pedestrian clearance and
clear visibility.
D.
Shrubs, ground covers and perennials used below shade trees within
parking lots shall be of species able to withstand the harsh microclimate
of a parking lot. Plant selection should take into consideration tree
growth and canopy cover and should be partially shade-tolerant species.
E.
To prevent conflicts with the opening and closing of automobile doors
and to reduce damage from automobile overhang, all shrub plantings
in parking lot islands and divider strips located adjacent to or abutting
parking stalls shall be set back a minimum of two feet from the curb
or edge of pavement.
F.
The placement of light standards shall be coordinated with the landscape
plan to avoid a conflict with electric lines and the effectiveness
of light fixtures.
G.
Plantings required within the parking areas are exclusive of other
planting requirements such as street trees and buffers.
[Ord. No. 2023-07, 11/1/2023]
1.
At a minimum, a 100-foot stream buffer is required adjacent to all
watercourses under Part 13 of the Shrewsbury Township Zoning Ordinance.
When these areas are part of a parcel or parcels of land being subdivided,
developed or redeveloped, they shall be planted or maintained as woodlands
as follows:
A.
Within 50 feet of a watercourse, the area shall be planted in trees
native to the region at a spacing of not less than 15 feet by 15 feet
or at a stocking rate that will result in a full canopy at maturity.
B.
Between 50 feet and 100 feet or greater, the area shall be planted
in trees and/or shrubs native to the Mid-Atlantic region at a spacing
that will result in a full canopy at maturity.
C.
The tree size or standard shall be 1 1/2 inches in caliber and
a minimum of six feet in height. Shrubs shall be two feet to three
feet in height. As an alternative, bare-root transplants with a minimum
height of two feet to three feet may be substituted, provided that
each transplant is protected by a five-foot shelter and a weed barrier
is placed around the base of the tree.
[Ord. No. 2023-07, 11/1/2023]
1.
Landscaping shall be required in and around all stormwater management
facilities with a minimum surface area of 1,000 square feet for the
purposes of:
2.
A planting plan shall be submitted in accordance with the following:
A.
Wet Meadows (Including Basin Floors).
(1)
Wet meadows and basin floors shall be planted with native wildflowers
and noninvasive grasses, the intent being to create a mixed meadow
of such plantings, where appropriate. Selection of plantings should
be based on whether the area in question is usually well-drained or
permanently wet and whether the area will be used for recreation purposes.
No woody plants shall be planted within the saturated zone of a stormwater
management basin.
(2)
Seeding by drills, corrugated rollers, cyclone or drop seeders
or hand seeding of such areas is preferred; however, hydroseeding
followed by hydromulching can be used on wet ground and steep slopes.
(3)
Fertilizers, as a nutrient supplement, shall not be used unless
it is documented that soil conditions warrant such use. Soil for planting
of wildflowers shall contain not less than 3% nor more than 10% organic
matter, as determined by an agricultural chemist, with certification
of test before planting.
(4)
Seeding should take place either between March 15 and June 1
or August 15 and October 15, or as specified by the seed distributor.
Planting areas shall be soaked to maintain a consistent level of moisture
for at least four to six weeks after planting.
(5)
Once established, a single annual mowing when plants are dormant
should be sufficient to maintain a wet meadow and/or basin floor.
B.
Wet Edges. Wet edges which remain wet all or most of the year shall
be planted with native wildflowers, grasses and shrubs. Plants to
be located on rims or banks which remain dry most of the year should
be planted with native species tolerant of dry soil conditions.
C.
Wooded Areas.
(1)
Where stormwater management facilities adjoin wooded areas,
native trees and shrubs shall be selected and planted so as to blend
with existing surroundings.
(2)
Plantings in such areas shall be of sufficient density to eliminate
the need for mowing.
(3)
It is recommended that clusters of trees and shrubs be planted
around stormwater management facilities, where applicable, to provide
for wildlife habitat, wind control and buffering and screening.
(4)
Vegetation shall be planted during appropriate times of the
year, predominantly between late March and mid-May and from early
October until evidence of ground freezing, depending upon the species
selected. Deciduous and evergreen trees and shrubs shall be planted
as directed by a trained arborist or forester.
D.
Slopes.
(1)
Where slopes are gentle, a mixture of native meadow grasses
and wildflowers shall be planted.
(2)
On steep slopes, dense-spreading native shrubs (shrubs tolerant
of dry soils) shall be planted. Heavy mat mulch shall be used during
the period of establishment.
(3)
No woody plant materials or trees shall be located on a constructed
or natural berm acting as the impoundment structure of a detention/retention
basin. Trees shall be located on the downstream side of an impoundment
berm a sufficient distance from the toe of the constructed slope to
assure that the toe of the slope is outside the dripline of the mature
species planted.
E.
Screening and Buffering.
(1)
Stormwater management facilities shall be appropriately screened
in a manner which complements the existing landscape and provides
sufficient access for maintenance. In many cases, complete perimeter
screening may not be necessary; however, it shall be the applicant's
responsibility to demonstrate in the submitted planting plan why this
is so.
(2)
Plantings shall consist of clusters of evergreens interspersed
with groupings of deciduous trees and shrubs. Single species planting
is prohibited.
(3)
It is encouraged that plantings native to Pennsylvania be used
which provide food and shelter for wildlife.
