Middle Housing is a permitted use in this zone subject to the following use-specific standards: 4.9.7.B.11-.14. RESUBMITTAL OF THE FOLLOWING IS REQUIRED: Correct plans, as noted in the comments below, along with a response letter indicating how all Site Zoning comments were addressed. 1. (Comment) Per UDC 7.6.8.A.1, one canopy tree is required for every 1,000 square feet of gross floor area of the development project. The approximate GFA for the house, accessory structure, and triplex combined is 3,809sqft. Therefore, 4 canopy trees will be required for this project. Only one species-labeled canopy tree is indicated on site. There appear to be other trees indicated but the species are not labeled. Please label the species of all proposed canopy trees and ensure that 4 canopy trees are proposed. 2. (Comment) Per UDC 7.6.8.B.1, 50% of canopy trees are required to be placed within the front yard setback area. If site constraints prevent new tree placement in the front yard, 5 shrubs can be used in its place, but that tree must be placed elsewhere on site. 3. (Comment) Per UDC 7.6.8.A.2, 330sqft of vegetative groundcover is required in the front yard. Please dimension and note this area on the site plan. 4. (Comment) Per UDC 7.6.8.B, newly planted trees and shrubs must follow relevant spacing requirements from utility lines. Please show how proposed trees and shrubs will not impact nearby proposed underground utility lines.
