Minimum Required Landscape Treatment Area. In all districts, a portion of the site visible from a street and comprising not less than 3% of the site area or gross floor area, whichever is greater, shall be landscaped with plant materials suitable for ornamenting the site, except that a pre-existing use in the R, C-1, C-2 and I-P-I districts shall not be deemed nonconforming by reason of failure to meet this requirement. Where nonconforming sites change use or are redeveloped, and existing development prevents installation of substantial vegetative or urban tree canopy improvements in compliance with this section, the property, business owner, or developer of the site shall provide in-lieu public amenities such as benches, public art, or water fountains subject to design review and a revocable encroachment permit, prior to occupancy. Where redevelopment of the site results in the demolition of 50% or more of the existing structure, as determined by the community development director, or designee, the owner or applicant shall be required to install landscaping to the extent practical for the site plan following demolition and incorporate such into any remodeling or other redevelopment plans.
The landscaped area provided for an expansion of a use in the R, C-1, C-2 and I-P-I districts shall be in addition to landscaped area existing prior to the expansion unless the pre-existing area exceeds the required minimum, in which instance it shall be counted in calculating the total area required.
All screening and landscaping shall be permanently maintained in a neat and orderly condition by the owner. Plant materials shall be watered, weeded, pruned, and replaced as necessary to screen or ornament the site. Within 30 days' written notice from the fire or community development department, the property owner shall abate any noncompliant screening or landscaping.
