[3] A high-density residential use is a residential use with a density of more than 6 dwelling units per acre. [4] A low-intensity nonresidential use is a nonresidential use with a floor area ratio (gross floor area/site area) no greater than 0.15 and an impervious surface coverage no greater than 30%. [5] A medium-intensity nonresidential use is a nonresidential use with a floor area ratio (floor area/site area) greater than 0.15 but no greater than 0.30, or an impervious surface coverage greater than 30%, but no greater than 60%. [6] A high-intensity nonresidential use is a nonresidential use with a floor area ratio (floor area/site area) greater than 0.30 or an impervious surface coverage greater than 60%. [7] The buffers listed in the table above may not be reduced except as expressly authorized by Sec. 16-10-2(G) or Sec. 16-10- 2(H) or by the granting of a variance in accordance with Sec. 19-26. In the event that bufferyard depth requirements conflict with zoning district setback requirements, the stricter standard governs. (F) Screen Types (1) Landscape Plan Variations (a) The quantities of plant materials noted below represent the number of deciduous canopy trees, full size evergreen trees, deciduous understory trees, evergreen understory trees, and shrubs that are necessary to create the type of screen specified. These stated quantities represent the number of each plant type (e.g. — deciduous canopy tree or shrub) that is necessary to achieve the specified type of screen. (b) The Planning Director has the authority to allow variations in the mix of plants required, up to a maximum of 25% of the total required number of each type of tree (i.e. — deciduous canopy tree, evergreen tree, deciduous understory tree, or evergreen understory tree) and up to a maximum of 35% of the shrubs [8] Child Care Center Class “A” must provide a 20’ bufferyard with Class C screen [9] Child Care Center Class “B” must provide a 20’ bufferyard with Class E screen [Amended on 7/21/2008 by OA 04-08.] (E) Overlap with Required Setbacks
