Buffer and Screen Standards The purpose of this requirement is to separate and buffer different land use types, screen roads and parking, and screen utility and loading areas. Continuous, year-round planting screens require, at the minimum, a double row of plants with triangulated spacing. Buffer and/or screen will be required between the parking lot and right-of-way along Hodgson Road and between 6681 Blue Heron Drive and the project site. Also, the buffering shrubs cannot be planted under tree canopy as shown in the landscape plan. The row of plants between the parking lot and right-of-way needs to be a double row of triangulated plants. The row of Techny arborvitae between 6681 Blue Heron Drive and the project site would meet requirements, but they cannot be planted under tree canopy. Buffers and screens as planned do not meet the requirements. Canopy Cover The purpose of this requirement is to mitigate the effects of vehicular hardscape by establishing tree canopy cover to intercept rainfall, protect pavement from sun deterioration, reduce the heat island effect, and improve aesthetics. Canopy cover standards call for a minimum of 40% canopy coverage. Vehicular hardscape planned: 5,800 sq. ft. Canopy cover requirement: 2,320 sq. ft. Canopy cover provided: 1,925 sq. ft. The 3 large trees near the future parking lot add 1,800 sq. ft. of canopy cover. The crabapple near the accessible parking space is worth 125 sq. ft. 2
