(C) How to use this section. This section is divided into the following:
Part 1. Landscaped Areas: § 156.402(D)
Part 2. Buffers: § 156.402(E)
Part 3. Street Yard Trees: § 156.402(F)
Part 4. Screening: § 156.402(G)
Part 5. General Landscaping, Screening and Buffering Provisions:
§ 156.402(H)
(D) Landscaped areas. All site plans requiring landscaping in accordance with this section shall have a landscape plan designed to provide landscaping in the following manner. These standards shall not apply in the B-1 District.
(1) Twenty percent of the total lot area shall be landscaped.
(2) No less than 1 canopy tree, 1 understory tree, and 2 shrubs shall be planted for each 1,000 square feet of landscape area required. Trees need to be evenly planted throughout the landscaped area, but may be staggered or clustered as necessary to maximize visual and screening objectives, and to meet the needs of the particular species of plants for root space, water, light, and air circulation. At the time of planting all canopy trees shall be at least 6 feet in height, all understory trees shall be at least 4 feet in height, and all shrubs shall be at least 1 foot in height.
(3) Landscape areas may include interior landscaping in parking lots and other vehicular use areas (see § 156.401C). However, the district boundary buffer requirements of division(E)(2)(c) below shall be provided completely, as required, in addition to these requirements. Resource conservation areas may be used to satisfy a maximum of 40% of the total required landscaped area.
(E) Buffers.
(1) Buffer defined. A buffer is a specified land area, located parallel to and within the outer perimeter of a lot and extending to the lot line, together with the planting and landscaping required on the land. A buffer may also contain, or be required to contain, a barrier such as a berm or wall where such additional screening is necessary to achieve the desired level of buffering between various land use activities. A buffer is not intended to be commensurate with the term "yard" or "setback."
(2) Buffer types. There are 4 types of required buffers that may occur on any given parcel (for the specific width and plant material for each buffer classification see division (3) below).
(a) Street buffers.
1. All new development with frontage on a commercial street or designated minor thoroughfare shall provide a Class A buffer as set forth in division (3) below.
2. Double frontage lots abutting a collector street or residential collector street shall provide a Class A buffer along the entire rear yard frontage.
(b) Parking buffers.
1. The perimeter of all parking areas and other vehicular use areas with frontage on any portion of an existing public right-of-way shall be screened by either a berm, a continuous landscaped hedge, a decorative masonry wall or any combination thereof.
2. At the time of installation, such screening shall be at least 30 inches in height. Any vegetative screen shall reach a maximum height of 36 inches within 2 years of planting.
3. No such buffer shall be required along an alley.
(c) District boundary buffers.
1. Required buffers. Perimeter compatibility is required along the boundaries of all incompatible zoning districts. The following table shall be used to determine the required buffer classification between adjacent districts.

2. Credit for existing plant material. Credit for existing plant material shall be allocated on a one-for-one basis for canopy trees, understory trees or shrubs. The size of material shall not be taken into account, except where such material is below the required minimum planting size.
(d) Project boundary buffers. The following project boundary buffers have been established to mitigate the effect of specific types of development on adjacent properties. Where project boundaries coincide with district boundaries the following project boundary buffers shall apply. A project boundary buffer shall not be required along a major thoroughfare, collector street, and minor thoroughfare (see division (a) above).
1. Open space residential subdivision. A buffer shall be required along all project boundaries of an open space subdivision (see § 156.203).
2. Planned development. A buffer shall be required along all project boundaries of a planned development (see § 156.203).
3. Manufactured home park. A buffer shall be required along all project boundaries of a manufactured home park (see § 156.302).
(3) Buffer classifications.
(a) The following table establishes the specific width and plant material for a variety of buffer classifications. The applicant is free to choose from each alternative (1, 2, or 3) in the respective buffer classification. Buffers planted below overhead utility lines shall apply any of the allowed buffer alternatives, except that understory trees shall replace any canopy trees at a rate of 2 understory trees per required canopy tree. The plantings below are intentionally over-planted at maturity, in order to provide an immediate beneficial impact.
(b) As determined by the Planning Director, a wall or berm meeting the standards in § 156.402 may be substituted in lieu of some of the required shrubs in buffer types A and B. A wall or berm is required in all Type C buffers.
