This rounds up to one (1) tree for projects under 1,000 SF. Vegetative groundcover within the front yard setback. The area for this can be calculated by multiplying the length of the street frontage (67.5 feet for this project), subtracting the width of the existing driveway, and then multiplying by five. Please label and include dimensions for the groundcover area on the site plan. All plant material used for landscaping must be selected (and drought-tolerant) from the adopted plant list located in Section 5-02.5.0 of the Technical Standards Manual found at https://codelibrary.amlegal.com/codes/tucson/latest/tucson_az_udc/0-0-0-11367 This code section also contains plant and tree maintenance.
