All residentially zoned developments with side or rear property lines adjacent to primary or secondary roadways shall construct a landscape buffer consisting of a 30'-0" setback with a continuous 4'-0" height minimum earthen mound. In addition to the mounding requirement a double staggered row of 6'-0" height minimum evergreen trees at 20'-0" maximum spacing and one 2" caliper minimum small class tree and two 18" height deciduous shrubs per each 40 lineal feet of property line are to be planted.

(2) Retail Commercial and Shopping Center Use Districts. There shall be a tree planted in a landscaped area for every 50 lineal feet of building perimeter or fraction thereof. Such landscaped areas shall be adjacent to the building, 64 square feet minimum in size, and shall contain a small, medium, or large class species tree in a planting bed, architectural planter, tree grate or on an earthen mound. Large, medium or small species trees shall be 2" minimum caliper. If tree grates or architectural planters are used, the minimum landscape area may be reduced to 36 square feet. Benches, or other appropriate landscape materials designed and located in a manner complimentary to the overall architecture of the surrounding buildings are encouraged. The intent of this regulation is to encourage an equally spaced landscape envelope around the perimeter of the building. Combining of tree planting areas to achieve overall compliance is acceptable.

These landscaped areas are to be constructed adjacent to the building and be a minimum of 20 square feet per tree converted to shrubs, groundcover or other ornamental plantings. The average initial height of these plantings is to be 24" minimum at 5'-0" maximum spacing. Freestanding signs and flagpoles are to be set in landscaped areas. These landscaped areas are to be a minimum two feet (2') larger than the foundation of the free standing signs or flagpoles on all sides and are to be landscaped on all sides with permanent shrubs, groundcover or other ornamental plantings. Annuals and perennials are permitted in combination with permanent plant materials. The average initial height of the plantings is to be 24" minimum. Irrigation shall be required on 75% - 100% of the entire property with emphasis on areas along primary and secondary roadways and 100% of all landscape areas adjacent to the structure.

Trees are to be arranged around all sides of the building within 64 square feet minimum of lawn or landscaped areas. In addition a minimum of 40 square feet of landscaped area shall be required for each 50 lineal feet of building perimeter or fraction thereof. These landscaped areas are to be constructed adjacent to the building and are to contain shrubs, ground cover, or other ornamental plantings. The average initial height of these plantings is to be 24" minimum at 5'-0" maximum spacing. The intent of this regulation is to encourage overall uniform landscaping treatment around the perimeter of the building. Combining of these planting areas to achieve compliance is acceptable providing that consideration is given to all facades. Free standing signs and flagpoles are to be set in landscaped areas. These landscaped areas are to be a minimum two feet (2') larger than the foundation of the free standing signs or flagpoles on all sides and are to be landscaped on all sides with permanent shrubs, groundcover or other ornamental plantings.
