Sec. 40-72. Reserved. <br /> <br />Sec. 40-73~ Landscaping groups. <br /> <br /> Where landscaping according to the specifications of a Landscaping Group is <br />required by this Chapter or is included as a condition of any permit or approval <br />granted under this Chapter, the design and planting of any landscaping shall meet <br />the standards of the designated Landscaping Group. The City of Portsmouth's <br />Landscaping Planting and Protection Manual includes suggested planting patterns <br />and species that will achieve the standards of these Landscaping Groups. <br /> <br />(a) <br /> <br />LANDSCAPING GROUP 1 (Opaque Screen). A buffer strip of land at least <br />fifteen (15) feet wide providing screening that is opaque from the ground <br />to a height of six feet, with intermittent visual obstructions from the opaque <br />portion to a height of at least twenty (20) feet. The opaque portion of the <br />screen is intended to exclude all visual contact between uses and to create <br />a strong impression of spatial separation. The opaque screen may be <br />composed of a wooden fence; a brick, stone, or masonry wall; landscaped <br />earth berm; planted vegetation or existing vegetation. The opaque portion <br />of the screen must be opaque in ali seasons of the year. Compliance of <br />planted vegetative screens will be judged on the basis of the average mature <br />height and density of foliage of the subject species or field observation of <br />existing vegetation, except that, at the time of planting, the fully opaque <br />portion of the screen should be of sufficient height and density to provide <br />complete visual obstruction within one year. At maturity, the portion of <br />intermittent visual obstructions shall not contain any completely <br />unobstructed openings more than ten (10) feet wide. The portion of <br />intermittent visual obstructions may contain deciduous plants. Trees <br />planted in the portion of intermittent visual obstruction shall be at least ten <br />(10) feet in height at the time of planting. <br /> <br />(b) <br /> <br />LANDSCAPING GROUP 2 (Semi-Opaque Screen) A screen meeting the <br />specifications of Landscaping Group 1 in 40-73 (a) above, except that the <br />screen must be opaque from the ground to a height of three (3) feet. <br /> <br />(c) <br /> <br />LANDSCAPING GROUP 3 (Broken Screen) A buffer strip of land at least <br />five (5) feet in width containing a combination of deciduous and coniferous <br />trees and shrubs designed to provide some buffering. Trees must be at least <br />ten (10) feet in height at the time of planting. At least one such tree shall <br />be planted in each twenty (20] foot-long section of the buffer strip. Shrubs <br />shall be at least twenty-four inches (24") in height at time of planting. At <br />least one (1) such shrub shall be planted in each six (6) foot-long section <br />of the buffer strip. <br /> <br />(d) <br /> <br />LANDSCAPING GROUP 4 (Interior Parking Area Landscaping) Parking area <br />landscaping consisting of plantings designed to provide shading and ground <br />cover containing any variety of trees, shrubs, plants and grasses, and <br />including at least one (1) tree per ten (10) parking spaces, said tree to be <br />at least ten (10) feet in height at the time of planting. All trees must be <br />adeq~mately dispersed throughout the parking area. Any portion of a single <br /> <br />100 <br /> <br /> <br />
