[Added 8-25-1994 by Ord. No. 140-D]
A.
Article 1, § 27, of the Constitution of
the Commonwealth of Pennsylvania states that people have a right to
clean air, pure water and to the preservation of the natural, scenic,
historic and aesthetic values of the environment. It is the intent
of these landscape planting requirements to protect this right by
conserving existing vegetation and/or requiring new plant material
in critical areas of land developments.
B.
Specifically, it is the intent of these landscape
planting requirements to conserve existing healthy plant communities,
such as woodlands, and to require new landscape plantings in critical
areas of new developments in order to:
(1)
Reduce soil erosion and protect surface water quality
by minimizing stripping of existing woodlands or tree masses.
(2)
Reduce stormwater runoff velocity and volume by providing
planting areas where stormwater can infiltrate.
(3)
Improve air quality by conserving existing or creating
new plantings which produce oxygen and remove carbon dioxide from
the atmosphere.
(4)
Provide animal habitat.
(5)
Provide wind breaks, shade and the other microclimate
benefits of trees and landscape plantings.
(6)
Conserve historically, culturally or environmentally
important landscapes such as wooded hillsides, scenic views or aesthetic
natural areas.
(7)
Preserve and enhance property values through the implementation
of good landscape architectural standards.
(8)
Provide planted buffers between land developments
which act to visually integrate a development into the existing landscape.
(9)
Provide planted and architectural visual screens around
visually obtrusive site elements within development.
(10)
Enhance the aesthetic appearance of the community
and provide privacy and beauty.
(11)
Improve traffic flow in parking lots by requiring
planted parking islands and medians to separate traffic.
(12)
Conserve energy by moderating solar radiation
and providing shade.
(13)
Improve the environment for pedestrians along
streets, parking lots and other pedestrian areas.
(14)
Aesthetically improve stormwater management
facilities, such as detention basins, without impairing function.
C.
Finally, it is the intent of this chapter to protect
the health, safety and welfare of the community by requiring planting
plans for major land developments to be sealed by a landscape architect
registered in the Commonwealth of Pennsylvania.
A.
Preservation of existing vegetation. Each mature tree,
tree mass or woodland on the site shall be designated "to remain"
or "to be removed" in accordance with the following criteria:
(1)
All subdivision and land developments shall be laid
out in such a manner as to minimize the removal of healthy trees and
shrubs on the site. Special consideration shall be given to major
specimen trees.
(2)
It shall be incumbent on the applicant to prove that
vegetation removal is minimized. If challenged by the Township, the
applicant shall produce evidence, such as written documents or plans
certified by a registered landscape architect or other qualified professional,
showing that no alternative layouts are possible and that no alternative
clearing or grading plan would reduce the loss of mature trees, tree
masses and woodlands.
(3)
A mature tree, tree mass or woodland shall be considered
"to remain" only if it meets all of the following criteria:
(a)
The outermost branches of the tree(s) are at
least five feet from any proposed buildings, structures, paving, parking
or utilities (overhead or underground).
(b)
The outermost branches of the tree(s) are at
least five feet from any proposed changes in grade or drainage, such
as excavations, mounding or impoundments.
(c)
The tree(s) are clear of any proposed sight
triangles and do not, by their location or apparent health, pose any
undue threat to the health, safety and welfare of the community.
(4)
Mature trees, tree masses or woodlands that do not
fit the above criteria shall be designated "to be removed." These
trees will be removed in the field during the construction process.
B.
Protection of existing vegetation. Existing vegetation designated "to remain," in accordance with Subsection A(3) above, as part of the landscaping of a subdivision or land development shall be identified in the field prior to any clearing and shall be physically protected throughout the construction process. A temporary physical barrier, such as a snow fence, shall be erected a minimum of one foot outside the dripline on all sides of individual trees, tree masses or woodlands prior to major clearing or construction. The barrier shall be placed to prevent disturbance and shall remain until construction is complete. The barrier shall be shown on the landscape plan.
C.
Hydrology. Alteration of existing drainage patterns
and water supply for the protected vegetation shall be minimized.
A.
Parking lots should be effectively landscaped with
trees and shrubs to reduce the visual impact of glare, headlights
and parking lot lights, to delineate driving lanes and define rows
of parking. Furthermore, parking lots should be adequately landscaped
to provide shade in order to reduce the amount of reflected heat and
to improve the aesthetics of parking lots.
B.
All parking lots with 10 or more stalls shall be landscaped
according to the following regulations:
(1)
One planting island shall be provided for every 10
parking stalls. There shall be no more than 10 contiguous parking
stalls in a row without a planting island.
(2)
The ends of all parking rows shall be divided from
drives by planting islands.
(3)
In residential developments, large parking lots shall
be divided by planting strips into smaller parking areas of no more
than 40 stalls.
(4)
In nonresidential developments, large parking lots
shall be divided by planting strips into smaller parking areas of
no more than 100 stalls.
(5)
Planting islands shall be a minimum of nine feet by
18 feet in area, underlain by soil (not base course material); mounded
at no more than a 4:1 slope nor less than a 12:1 slope, and shall
be protected by curbing or bollards. Each planting island shall contain
one shade tree plus shrubs and/or ground cover to cover the entire
area.
(6)
All planting strips shall be a minimum of eight feet
wide. Strips shall run the length of the parking row, underlain by
soil, mounded at no more than a 4:1 slope nor less than a 12:1 slope,
and shall be protected by curbs, wheelstops or bollards. Planting
strips shall contain plantings of street-type shade trees at intervals
of 30 to 40 feet plus shrubs and/or ground cover to cover the entire
area at maturity.
(7)
The placement of light standards shall be coordinated
with the landscape plan to avoid a conflict with the effectiveness
of light fixtures.
A.
Street trees shall be required:
(1)
Along all existing streets when they abut or lie within
the proposed subdivision or land development.
(2)
Along all proposed streets.
(3)
Along access driveways that serve five or more residential
dwelling units.
(4)
Along access driveways that serve two or more nonresidential
properties.
(5)
Along major walkways through parking lots and between
nonresidential buildings as recommended by the Township Planning Commission.
B.
The street tree requirements may be waived by the
Board of Commissioners where existing vegetation is considered sufficient
to maintain scenic views of open space, farmland, natural features
or other valued features.
C.
Street trees shall be located between the ultimate
right-of-way line and the building setback line and shall meet the
following standards.
(1)
Trees shall be planted a minimum distance of five
feet and a maximum distance of 15 feet outside the ultimate right-of-way
line. However, in certain cases, as follows, the Board of Commissioners
may permit trees to be planted within the ultimate right-of-way:
(2)
In nonresidential developments, trees shall be located
within a planting bed within the front yard setback at least 10 feet
in width, planted in grass or ground cover. In areas where wider sidewalks
are desirable or space is limited, tree planting pits may be used.
(3)
Trees shall be located so as not to interfere with
the installation and maintenance of sidewalks and utilities. Trees
shall be planted a minimum distance of three feet from curbs and sidewalks,
15 feet from overhead utilities and six feet from underground utilities.
(4)
Trees shall be planted at a ratio of at least one
tree per 50 linear feet of frontage or fraction thereof. Trees shall
be distributed along the entire frontage of the property, although
they need not be evenly spaced.
Landscaping shall be required in and around
all stormwater management basins according to the following:
A.
All areas of stormwater management basins, including basin floors, side slopes, berms, impoundment structures or other earth structures, shall be planted with cover vegetation such as lawn grass or naturalized plantings specifically suited for stormwater basins (see § 215-56 for recommended plants for stormwater basins).
(1)
Lawn grass areas shall be sodded or hydroseeded to
minimize erosion during the establishment period and, once established,
these areas shall be maintained at a height of not more than six inches.
(2)
Naturalized cover plantings, such as wildflowers,
meadows and nonaggressive grasses specifically designed for the permanently
wet, intermittently wet and usually dry areas of stormwater basins,
may be planted as an alternative to lawn grass, given:
(3)
Trees and shrubs shall be allowed in and around stormwater
basins, given they do not interfere in the proper function of the
basin and no trees are planted on or within 30 feet of an impoundment
structure or dam.
B.
Basin shape shall incorporate curvilinear features
to blend with the surrounding topography.
C.
Minimum grades inside stormwater basins shall be 2%
and maximum side slopes of the basin shall be 33% (3:1 slope).
A.
All subdivisions and land developments shall be landscaped
with the following two components:
(1)
Property line buffers that act to integrate new development
with its surroundings and to separate incompatible land uses.
(2)
Site element screens that act to minimize or eliminate
views to certain site elements located within 100 feet of property
lines or road rights-of-way (either public or private).
B.
The following requirements are minimum standards;
additional plant material, berms or architectural elements may be
included in the plan, at the applicant's discretion.
C.
Property line buffer requirements.
(1)
Property line buffers shall be required for the following types of development and as otherwise specified in the Lower Pottsgrove Zoning Ordinance (Chapter 250):
(2)
An on-site investigation by the applicant shall determine
the adjacent land uses along each property boundary. In the case of
vacant land, the existing zoned uses shall be used. The existing or
zoned uses shall be noted on the plan. In the case of several permitted
uses on a site the most restrictive requirements shall apply. The
Township shall have final approval of interpretation of land uses
or the Zoning Map.
(3)
The quantity and type of plant material required shall
be determined by the intensity of the proposed land use and the adjacent
land use, vacant land or zoning district according to Table 1.[1]
[1]
Editor's Note: Table 1, Property Line Buffers, is included at the end of this chapter.
(4)
Buffer area and location and dimensions.
(a)
A buffer area of not less than 25 feet nor more than 50 feet in width shall be established along all property lines unless otherwise specified in the Zoning Ordinance (Chapter 250). For lots in the CO Commercial Office District, LCO Limited Commercial and Office District and NC Neighborhood Commercial District, the buffer shall be of sufficient width to support the required plants.
(b)
The buffer area may be included within the front,
side or rear yard setback.
(c)

discretion of the Board of Commissioners. The minimum quantities and/or
visual effect of the existing vegetation shall be equal to or exceed
that of the required buffer.
(8)
Existing topographic conditions, such as embankments
or berms, in conjunction with existing vegetation, may be substituted
for part or all of the required property line buffers, at the discretion
of the Board of Commissioners. The minimum visual effect shall be
equal to or exceed that of the required buffer or screen.
D.
Site element screens.
(1)
Site element screens shall be required in all proposed
land developments around the following site elements when these are
located partially or fully within 100 feet of the property line or
existing road right-of-way. (In the CO, LCO and NC Districts, site
element screens are not required for site elements within 100 feet
of property lines adjacent to industrial uses. Such distance, however,
shall not exceed the dimensions of the property.)
(a)
Parking lots of three or more stalls.
(b)

case of vacant land, the uses allowed in the existing zoning district
shall be used. These existing or zoned uses shall be noted on the
plan. In the case of several permitted uses on a site, the most restrictive
requirements shall apply. The Township shall have final approval of
any interpretation of land use or map.
(3)
The type of site element screen required shall be
determined by the site element and the adjacent existing land use
or zoned use, in the case of vacant land, according to Table 2.[2] In the CO, LCO and NC Districts the type of screen shall
be determined by the site element and the area available for screening
in accordance with Table 3.[3]
[2]
Editor's Note: Table 2, Site Element Screens, is included at the end of this chapter.
[3]
Editor's Note: Table 3, Site Element Screens - Commercial Office, Limited Commercial and Office, and Neighborhood Commercial Districts, is included at the end of this chapter.
(4)
Site elements not included in the above list that
have similar visual impact shall be screened in accordance with requirements
for the most similar elements as determined by the Township.
(5)
Screen location. The site element screen shall be
placed between the site element and the property line and shall be
designed to block views to the maximum extent possible. The screen
shall be located as close as possible to the site element and shall
surround the element without impeding function or encroaching on sight
triangles.
(6)
Screen types and design criteria. The following types
of screens shall be used where specified in Table 2. For lots in the
CO, LCO and NC Districts, refer to Table 3.
(a)

of the Board of Commissioners. The minimum quantities and/or visual
effect of the existing vegetation shall be equal to or exceed that
of the required buffer.
(8)
Existing topographic conditions, such as embankments
or berms, may be substituted for part or all of the required property
line buffers, at the discretion of the Board of Commissioners. The
minimum visual effect shall be equal to or exceed that of the required
screen.
(9)
The applicant may propose the use of alternate screen
types or changes in plant materials or designs which fulfill the intent
of this chapter, with the approval of the Board of Commissioners.
The following standards shall apply to all plant
materials or transplanted trees as required under this chapter.
A.
General requirements.
(1)
The location, dimensions and spacing of required plantings
should be adequate for their proper growth and maintenance, taking
into account the sizes of such plantings at maturity and their present
and future environmental requirements such as wind, soil, moisture
and sunlight.
(2)
Plantings should be selected and located where they
will not contribute to conditions hazardous to public safety. Such
locations include, but are not limited to, public street rights-of-way,
underground and aboveground utilities, and sight triangle areas required
for unobstructed views at street intersections.
B.
Plant specifications.
(1)
All plants shall meet the minimum standards for health,
form and root condition as outlined in the American Association of
Nurserymen (AAN) Standards.
(2)
All plant material shall be hardy and within the USDA
Hardiness Zone 6 applicable to Montgomery County, Pennsylvania.
(3)
Canopy trees, sometimes called shade trees, shall
reach a minimum height and spread of 30 feet at maturity, as determined
by the AAN Standards, and shall be deciduous. New trees shall have
a minimum caliper of 2 1/2 inches at planting.
(4)
Ornamental trees or large shrubs shall reach a typical
minimum height of 15 feet at maturity, based on AAN Standards. Trees
and shrubs may be deciduous or evergreen and shall have a distinctive
ornamental character, such as showy flowers, fruit, habit, foliage
or bark. New ornamental trees shall have a minimum height of six feet
and one-and-one-half-inch caliper. New large shrubs shall have a minimum
height of 2 1/2 to three feet at time of planting.[1]
(5)

New shrubs shall have a minimum height of 18 inches at time of planting.
(6)
Evergreen trees shall reach a typical minimum height
of 20 feet at maturity, based on AAN Standards for that species, and
shall remain evergreen throughout the year. New evergreens shall have
a minimum height at planting of six feet.
C.
Maintenance.
(1)
Required plant material shall be maintained for the
life of the project to achieve the required visual effect of the buffer
or screen. It shall be the ultimate responsibility of successive property
owners to ensure that the required plantings are properly maintained.
Dead or diseased plant material shall be removed or treated promptly
by the property owner and replaced at the next growing season.
(2)
Safety. All sight triangles shall remain clear, and
any plant material that could endanger safety, such as unstable limbs,
shall be removed and the plant material replaced if necessary. It
shall be the responsibility of the property owner to maintain all
plantings and architectural elements to ensure a safe environment.
(3)
Maintenance guidelines for the plantings are encouraged
to be published by the planting plan designer to be used by grounds
maintenance personnel to ensure that the design's buffering and screening
concepts are continued.
D.
Landscape bond.
(1)
Any tree or shrub that dies within 18 months of planting
shall be replaced by the current landowner or developer. Any tree
or shrub that within 18 months of planting or replanting is deemed,
in the opinion of the Township, not to have survived or not to have
grown in a manner characteristic of its type shall be replaced. Substitutions
for certain species may be made only when approved by the Township.
(2)
The developer or landowner shall deposit with the
Township a sum of money in the form of cash, certified check, letter
of credit or bond equal to a minimum of 15% of the total landscaping
costs to cover the cost of replacing, purchasing, planting and maintaining
all dead, dying, defective or diseased plant material for a period
of 18 months.

show:
As used in this chapter, the following terms
shall have the meanings indicated:
Diameter of a tree's trunk measured 12 inches above the ground.
Any tree of six inches or more in caliper, whether standing
alone, in tree masses or woodlands. A mature tree shall be a healthy
specimen and shall be a desirable species as determined by the Township
Landscape Architect.
To reduce to the smallest amount possible. "Minimize" does
not mean to "eliminate" but rather that the most substantial efforts
possible under the circumstances have been taken to reduce the adverse
effect of the action (such as grading, clearing, construction, etc.).
Proper sight lines must be maintained at all intersections
of streets. Measured along the center line, there should be a clear
sight triangle of 75 feet from the point of intersection based on
the posted speed limit. No building or present or future obstruction
will be permitted in this area.
Any tree with a caliper that is 75% or more of the record
tree of the same species in the Commonwealth of Pennsylvania.
A grouping of three or more trees, each at least 1 1/2
inch in caliper, within a one-hundred-square-foot area.
A stand of predominantly native vegetation covering at least
one acre, consisting of at least fifty-percent cover of mature trees
of varying size.
[Added 9-26-1996 by Ord. No. 199]
The landscape of the Sanatoga Village District
expresses the small lots and intimate scale typical of most villages.
Existing landscape regulations, appropriate for larger suburban-type
developments, are modified to reflect this difference in scale as
follows:
A.
All proposals shall comply with § 215-50 of this chapter, minimizing loss of existing vegetation.
B.
Property line buffers may be waived in land developments under one acre. All other land developments shall comply with the requirements in § 215-54 for the Limited Commercial and Office District in this chapter.
C.
Site element screens shall be required as in § 215-54D of this chapter and shall comply with Table 3 therein.[1]
