1 b. If the housing product is an attached style, the number of plantings shall be determined based <br /> 2 on canopy cover. To fulfill the planting requirements, a combination of trees and shrubs shall <br /> 3 meet or exceed the minimum required canopy cover square footage. <br /> 4 c. The minimum canopy cover required shall be calculated as follows: <br /> 5 1. Determine ratio of impervious area (including stormwater ponds)to entire site. <br /> 6 2. Multiply the impervious area/site area ratio by the square footage of the pervious area to <br /> 7 calculate the required canopy cover square footage for the project area. <br /> 8 3. The following formula shall be utilized to determine the average canopy cover of a species: <br /> 9 [(Minimum + maximum spread) = 4]2 x x (0.65 for preferred species or 0.50 for <br /> 10 acceptable species, as identified in the Ramsey Tree Book). <br /> 11 d. Minimum size of plantings. Required trees and shrubs shall meet or exceed the following size <br /> 12 standards: <br /> Plant Type Size <br /> Deciduous Tree 1 inch caliper <br /> Coniferous Tree 5 feet in height <br /> Ornamental Tree 1 inch caliper <br /> Deciduous Shrub 2 feet in height <br /> Evergreen 2 feet in height or width, based on growth characteristics <br /> 13 <br /> 14 471-474 Reserved. <br /> 15 <br /> 16 475 Screening <br /> 17 (1) Rooftop HVAC and other mechanical units must be screened from views from the property <br /> 18 lines using the following means: <br /> 19 a. Proper placement on the roof. <br /> 20 b. An integrated screen panel that is architecturally compatible with the building. <br /> 21 C. Parapet heights sufficient for screening the views. <br /> 22 (2) Ground-mounted HVAC and other mechanical units for all structures other than single-family, <br /> 23 two-family, and townhomes must be screened from views from the property lines using the <br /> 24 following means: <br /> 25 a. Privacy fencing <br /> 26 b. An integrated screen panel that is architecturally compatible with the building. <br /> 27 C. Landscaped berms. <br /> 28 (3) Density/Use Buffering and Transitioning. Within the additional lot depth/width area described <br /> 29 in Section 430, the following options are required when different residential uses abut each <br /> 30 other or residential uses abut an existing or planned non-residential use. <br /> 31 a. A continuous six-foot privacy fence with 2-inch caliper overstory trees planted every 20 <br /> 32 feet, roughly evenly spaced. <br /> 33 b. A vegetative buffer containing four 2-inch caliper overstory, four 6-foot evergreen, and <br /> 34 four 1.5-inch understory trees planted per 100 feet of property boundary on both sides of <br /> 35 a berm with a maximum slope of 4:1. <br /> 36 C. If this area is used for storm water management, both sides of the basin shall be lined <br /> 37 with 2-inch caliper overstory trees at the rate of one tree per 20 feet, roughly evenly <br /> 38 spaced and large shrubs at the rate of one per three feet. The side of the basin closest to <br /> 39 a non-residential use shall add one 6-foot evergreen tree per 40 feet, roughly evenly <br /> 40 spaced. <br /> 41 d. Other options may be approved by the City Council based on site and adjacent site <br /> 42 conditions and existing vegetation. <br /> 43 <br /> 44 476-479 Reserved. <br /> 45 <br /> Page 60 of 141 <br />
