facilities; loading facilities and swimming pools and <br />recreational areas. Screening may also lir, required where <br />different zoning districts abut. <br />Description of Screening Types. <br />Three (3) basic types of screening are hereby established: <br />Type "A", Opaque Screen; Type "B", Semi -Opaque Screen; and <br />Type "C", Intermittent Screen. <br />i• le "A", Opaque Screen. This screening class shall <br />normally be used to screen very intensive uses, such as <br />extraction, transportation, utilities, industrial, <br />heavy commercial, service stations, and high intensity <br />recreation uses. An opaque screen is intended to <br />completely exclude all visual contact between uses. <br />The Type "A" Screen shall be completely opaque from the <br />ground up to a height of at least six (6) feet, with <br />large trees utilized as intermittent visual ob- <br />structions from the opaque portion to a mature height <br />of at least twenty (20) feet. The opaque screen may be <br />composed of a wall, fence, landscaped earth berm, <br />planted vegetation, or existing vegetation, or any <br />combination thereof wfhich M=aintains a completely opaque <br />screen of at least six (6) feet in height. Compliance <br />of planted vegetative screens or natural vegetation <br />will be judged on the basis of the average height and <br />density of foliage of the subject species at the time <br />of planting, or field observation of existing vege- <br />tation. The six (6) foot opaque portion of the screen <br />must be opaque in all seasons of the year. <br />>>• TypeSe i -Opaque Screen. This screening class <br />shall nor as y be used to screen moderate intensity <br />uses, such as non -heavy coTFercial uses, medium inten- <br />sity recreation uses, and CO-nunity service areas. The <br />semi-opaque screen is intendea to partially block <br />visual contact between uses. The Type "B" screen shall <br />be completely opaque fro,.-: the ground up to a height of <br />at least three (3) feet, raith large trees utilized as <br />intermittent visual obstructions from the opaque <br />portion to a mature height of at least twenty (20) <br />feet. The semi-opaque screen may be composed of a <br />wall, fence, landscaped earth berm,., planted vegetation, <br />existing vegetation or any cer,bination thereof which <br />maintains a completely opaque screen of at least three <br />(3) feet. Compliance of planted vegetative screens or <br />natural vegetation will be judged on the basis of the <br />average mature height and density of foliage of the <br />subject species, or field observation of existing <br />vegetation. <br />Type "C", Intermittent Screen. This screening class <br />shall norma y e used to screen low intensity uses <br />such as low intensity recreation uses, institutional <br />uses, and multi -family uses. The intermittent screen <br />is intended to create the impression of a separation of <br />spaces without necessarily eliminating visual contact <br />between the spaces. The Type "C" screen shall utilize <br />large trees as intermittent visual obstructions from <br />the ground up to a mature height of at least twenty <br />(20) feet. The intermittent screen may be composed of <br />fences, berms, and either existing or planted vege- <br />tation. Compliance of planted vegetative screens or <br />natural vegetation will be judged on the basis of the <br />average mature height and density of foliage of the <br />subject species, or field observation of existing vege- <br />tation. <br />d.
