Parking lot landscaping standards of this section establish minimum landscaping requirements for the perimeter and interior of off-street parking areas, access driveways, and drives to and from drive-up windows. The general purpose of such landscaping is to reduce the visual impact of parking and pavement. See Chapter 10-38 Parking Section and the project's zone Development Specification Standards page for parking lot locations and setbacks. Parking lot landscaping may count towards meeting the Landscaping Performance Minimum Requirements.
A. Applicability to All Off-Street Parking Lots: Parking lot landscaping shall be approved through the Design Review process and shall not be less than the minimum standards of this chapter.
B. Perimeter Parking Lot Landscaping: The parking lot perimeter landscaping requirements apply to all off-street parking lots that are not otherwise fully screened from view of adjacent public rights-of-way. Landscape borders shall be used for open space and landscaping. No structures or paving shall be located within the border area, with the exception of walls, walkways or other features incorporated into the landscaping. If adjoining properties share or abut parking lots, the perimeter landscape requirements are waived for the two (2) adjoining sides of each parking lot and the two adjoining parking lots will be calculated as one.
1. If the parking lot's front setback is twenty-five feet (25') or more, the border landscape shall conform to the Type "A" Separation in figure 10-38-7
B. Border trees shall be planted at an average of twenty feet (30') on center.
2. For Type "B" and "C", separation shrubs must be planted at an average of three feet (3') on center and small trees at fifteen feet (15') on center along the entire border.
3. For Type "C" separations, the earth berm or wall combination shall be a minimum three feet (3') in height measured from the nearest street's top back of curb and in combination with plant material to achieve a minimum four foot (4') tall solid screen at installation.
4. For Type "D" separations, when a wall is constructed it must be four feet (4') in height and in combination with plant material placed at six feet (6') on center.
5. For parking lots containing twenty-five (25) stalls or fewer, five feet (5') shall be the minimum perimeter border width for the rear and side borders of the parking lot.
6. For parking lots containing more than twenty-five (25) stalls, eight feet (8') shall be the minimum perimeter border width for the rear and side borders of the parking lot.
7. Side and rear parking lot perimeter borders shall be landscaped with plant material covering a minimum of fifty percent (50%) of the total border surface area measured at the plant maturity.
8. For Type "E" separation requirements when new development is abutting Highway 89/91.
9. No longer needed.
C. Parking Lot Interior Landscaping Requirements: The parking lot interior landscaping requirements apply to all off-street parking lots that contain five or more parking spaces. Only areas specified in figure Section 10-39-7
C can be counted towards a project's interior parking lot landscaping requirements. Interior planting areas are required within all parking lots as specified in this subsection.
1. At least eighteen (18) square feet of interior landscape planting area shall be provided within the interior of an off-street parking area for each parking stall contained with the parking area.
2. Landscaping located within the interior of a parking area shall be evenly dispersed throughout the area. All planting areas shall be protected to prevent damage by vehicles and vehicle overhang.
3. When the number of stalls in a parking area exceeds the number of required parking stalls defined in Chapter 10-39
by one hundred twenty five percent (125%), the minimum interior parking lot landscaping requirements shall be increased to thirty-six (36) square feet of interior landscaping for each parking space contained within the parking stall.
4. All aisles shall have landscaped areas at each end of the aisle.
5. One (1) tree shall be planted within the interior of a parking area per every ten (10) stalls contained within the area. Interior parking area landscapes shall have a minimum of fifty percent (50%) plant material coverage measured at plants maturity.

6. For all commercial and industrial zones, parking lot landscaping for tractor/trailer truck service areas, loading, docking, staging, and truck parking lots, the Planning Commission shall review and determine landscape requirements. The Planning Commission may reduce or eliminate the requirement on the interior of parking lots and paved areas. However, the Planning Commission shall require, at least, the quantity of plant material required for interior landscaping to be located at the periphery of parking lots to screen vehicles and services from public view and to provide buffer landscaping between adjacent properties.
