   3. Equivalent Acres: as used in this section, open space requirements shall be calculated based on equivalent acres, where different types of open space qualify as having more or fewer acres. For each acre of required open space, the requirement may be met through a variety of open space types, according to the table below and as defined in this section:

      1. Equivalent Acre Formula
         Category of Open Space Provided	Multiplier
         Open Space with No Access	0.15
         Sensitive Lands - Limited Access	0.33
         Improved Existing City-Owned Open Space	0.67
         Detention Basin - Limited Access	0.67
         Detention Basin - No Access	0 - No Credit

The area of this landscape buffer shall not be used to satisfy the landscape area requirements of this Section.
      
   2. The landscape buffer areas shall be improved with a minimum of one (1) screening tree spaced at each fifteen-foot interval of the property boundary being screened.

   3. The landscape setback identified above shall be established and maintained along all street frontages between any perimeter wall, building, on-site parking area or outdoor storage area and the nearest point of the existing or future required street/sidewalk improvements (the back of an existing sidewalk, the line equal to the back of a future required sidewalk, or the back of the street curb where no sidewalk is required). However, for reverse street frontage the landscape widths shall be in accordance with adopted street cross-section designs.
      
   4. Where parkstrips have a minimum width of eight (8') feet, turf shall be limited to 30% of the total landscape street frontage area [see also VZC 15.40.090(5) for additional requirements]. This minimum quantity of trees, shrubs and vegetative groundcover shall be located between the curb and the landscape setback. The street frontage landscaping shall be designed and located to enhance the proposed development project and the streetscape.
      
   5. The installation of street trees, shrubs and vegetative groundcover shall be required for all applicable projects in an amount equal to or greater than one tree and ten (10) shrubs for every twenty (20) feet of street frontage or one (1) tree and ten (10) shrubs for every forty (40) feet of street frontage for residential subdivisions and vegetative groundcover as required to meet a minimum of sixty-five (65) percent of the total street frontage landscaped area.
