(a) Parking Landscape Plan.
The Commission shall approve a parking landscape plan that satisfies the technical requirements of the regulations of the Commission, or waive the requirements of this § 14-803(5) (Parking Landscape and Screening) if the Commission determines that it would be impractical to provide the required landscape, before L&I may issue a zoning permit.
(b) General Requirements.
All parking landscape and screening required by this § 14-803(5) (Parking Landscape and Screening) shall comply with the general landscape standards set forth in § 14-705(1)(c) (General Standards) and the installation and maintenance requirements set forth in § 14-705(3) (Installation and Maintenance of Landscape and Trees).
(c) Perimeter Screening From Abutting Residential District.
(.1) When a parking lot or surface parking area associated with a parking garage (including but not limited to driveways and aisles) abuts a Residential district, a continuous screening wall, berm, fence, or row of plants at least five ft. tall shall be provided between the surface parking lot or surface parking area and the Residential district.
(.2) The screening material shall be designed to provide seventy-five percent (75%) opacity on a year-round basis beginning one year after planting along the full required height and length of the screening buffer.
(.3) Screening fences shall be constructed of ornamental metal or wood; chain-link and barbed wire are prohibited as fencing material. The side of the fence presenting a more finished appearance, or the side without bracing supports, shall face towards the Residential district.
(d) Perimeter Screening from Public Streets for Parking Lots.
(.1) Where any surface parking lot is located along a street frontage, a landscaped area shall be installed along the entire length of the perimeter of the surface parking lot that is located along a street frontage to screen the view of the parking area from the street. Except as provided in § 14-803(5)(d)(.2) below, the landscaped area shall be at least equal to the required setback, but in no case less than five ft. wide.
(.a) Trees must be provided within the required landscaped area at a rate of at least one tree per 35 ft. of linear frontage. Such trees may be placed at regular or irregular intervals, provided that there is at least 15 ft. of space between tree trunks.
(.b) Shrubs shall be planted at an interval of three shrubs per 25 ft. of linear frontage and must have a mature height of at least two ft.
(.2) Where a five ft. wide perimeter landscape area is not feasible based on existing site or topography constraints, as an alternative to the tree and shrub plantings required by § 14-803(5)(d)(.1) above, a decorative masonry wall or ornamental fence at least three ft. in height may be installed. The decorative wall or ornamental fence may be installed on a berm if the combined height of berm and wall or fence is at least three ft. in height.
(.a) The decorative masonry wall must be constructed of brick, stone, decorative block wall, or concrete block with stucco finish, but shall not be constructed of uncolored or painted concrete block.
(.b) The ornamental fence must satisfy the requirements for screening fences in § 14-803(5)(c)(.3) (Perimeter Screening From Abutting Residential District).
(e) Interior Landscape Requirements for Parking Lots.
(.1) A minimum of ten percent (10%) of the interior surface parking lot in all districts and off-street loading areas in all districts except I-2, I-3, and I-P, calculated as the total of area in all surface parking spaces and surface drive aisles, shall be planted with landscape. 703
(.2) If the applicant installs a vegetated roof on a primary or accessory structure on the same lot, the amount of interior parking lot landscape may be reduced by one sq. ft. for each one sq. ft. of vegetated roof area installed.
(.4) Internal landscaped areas shall be dispersed on the site to break up the perception of large uninterrupted expanse of pavement. Landscaped areas shall be a minimum of six ft. wide. In surface parking lots containing more than 50 parking spaces, interior landscaped areas should be used to break up those spaces into groups of no more than 20 contiguous parking spaces.
(.5) One tree shall be planted per 300 sq. ft. of interior landscaped area. A minimum of thirty percent (30%) of the required trees shall include deciduous shade trees from DPR's Recommended Street Tree List.
(.6) Required perimeter and interior landscaped areas shall maximize effective stormwater management by incorporating any one of the following:
(.a) A bioretention system that is designed in accordance with the Philadelphia Stormwater Management Guidance Manual; or
(.b) Curbs at the edge of the required perimeter and interior landscaped areas to protect the plants, with planted areas installed at a lower grade than the parking lot pavement, and curbing shall have openings allowing drainage from the pavement to enter and percolate through the landscaped areas.
