The pedestrian system must also connect public open space or parks, commercial, office and institutional developments when existing development does not preclude such connection. Development patterns must not preclude eventual site-to-site connections, even if an adjacent site is not planned for development at the time of the applicant's development.

12.

Perimeter landscaping . Any off-street parking area, other than for a single-family or duplex dwelling, shall be effectively screened by a sight-obscuring evergreen planting on each side which adjoins property situated in a residential zone, the premises of any school or like institution, or a public or private street.

Screening along all public or private streets shall be a minimum of three feet high.

Broadleaf trees must be at least two caliper inches at the time of plantings; or conifer trees must be at least five feet tall at the time of planting. Trees must be dispersed throughout the parking area to provide shade for the parking area. Some trees may be grouped, but the groups must be dispersed.
