[Added 7-12-1993 by Ord. No. 196]
A. 
Article I, § 27, of the Constitution of the Commonwealth of Pennsylvania states that people have a right to clean air and 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 windbreaks, shade and 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 these regulations to protect the health, safety and welfare of the community by requiring planting plans containing the seal of a landscape architect, arborist or horticulturalist registered in the Commonwealth of Pennsylvania for all nonresidential land developments, all attached residential housing developments and all detached residential housing developments of more than five parcels/units.
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 subdivisions 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 municipality, 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), 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 drip line on all sides of individual trees, tree masses or woodlands prior to major clearing or construction. The barrier shall be placed to prevent disturbance to or compaction of soil inside the barrier 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.
D. 
Transplanting existing plant material. Specimen trees or individual trees from woodlands or tree masses designated to be removed are encouraged to be transplanted from one area of the site to another. Transplanted trees must conform to the requirements of §§ 122-72 and 122-73 of this article.
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 to 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 15 parking stalls. There shall be no more than 15 contiguous parking stalls in a row without a planting island.
[Amended 6-8-1998 by Ord. No. 263]
(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 by 18 feet in area, underlain by soil (not base course material); mounded at no more than a four-to-one slope, nor less than a twelve-to-one slope; and shall be protected by curbing or bollards. Each planting island shall contain one shade tree, plus shrubs and 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 four-to-one slope, nor less than a twelve-to-one slope, and shall be protected by curbs, wheel stops or bollards. Planting strips shall contain plantings of street-type shade trees at intervals of 30 to 40 feet, plus shrubs and 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.
(8) 
Plant materials shall comply with the requirements of § 122-72 herein. The use of plantings selected from the list of recommended plant material (§ 122-73) is encouraged.
C. 
All parking lots shall be screened from public roads and from adjacent properties as required in § 122-71 herein.
A. 
Street trees shall be required:

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 Planning Commission.
B. 
The street tree requirement may be waived by the governing body 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 governing body may permit trees to be planted within the ultimate right-of-way:
(a) 
In areas such as existing villages where front yards may be located within the ultimate right-of-way.
(b) 
In cases where closely spaced rows of street trees may be desirable and future street widening is considered unlikely.
(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, fifteen 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 40 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.
(5) 
Trees shall comply with the requirements of § 122-72 herein. The use of tree species selected from the list of recommended plant materials is encouraged (§ 122-73).
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 § 122-73 for recommended plants for stormwater basins).
(1) 
Lawn grass areas shall be sodded or hydro-seeded 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:
(a) 
The plantings provide continuous cover to all areas of the basin.
(b) 
The plantings do not interfere in the safe and efficient function of the basin as determined by the Township Engineer.
(3) 
Trees and shrubs shall be allowed in and around stormwater basins, except where there is a fill embankment, 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 mowable side slopes of the basin shall be 25% [four-to-one slope]. If the slope is not to be mowed, the maximum side slope may be 33% [three to one slope], provided that there is suitable permanent vegetation as approved by the Township Engineer.
D. 
If the basin is to be dedicated to the township, it must be graded and seeded to a turf grass condition.
E. 
Stormwater basins shall be screened with landscaping from adjacent properties according to § 122-71.
A. 
All subdivisions and land developments shall be landscaped with the following two components:
