A. 
All parking areas of over twenty thousand (20,000) square feet shall have a minimum of ten percent (10%) of the parking area, maneuvering area and loading space landscaped as a means to reduce the barren appearance of the lot and to reduce the amount of stormwater runoff.

B.

C. 
All outside storage areas shall be screened by fencing and landscaping a minimum of five (5) feet in depth unless it is determined by development plan review that such screening is not necessary because stored materials are not visually obtrusive. The five (5) foot deep landscaped area can occur within the street right-of-way abutting the property line.
D. 
All portions of a lot not devoted to building, future building, parking, storage or accessory uses shall be landscaped in a manner appropriate to the stated purpose of this chapter.

A six (6) foot high solid wood or equivalent fence is also required. Substitute fencing, including but not limited to chain link fence with slats, may be approved by the city planner upon application of the developer and adjacent residential property owners when such fencing shall provide buffering consistent with the purpose and intent of this chapter. The term “adjacent residential property,” for purposes of this section, means abutting property, and lots immediately adjacent to abutting property, and shall not mean property across a public road, a private street or a landscape buffer of similar width.
K. 
Landscaping shall not conflict with the safety of those using adjacent sidewalks or with traffic safety. Safety features of landscaping shall be discussed at the time of development plan review, if necessary.
L. 
Quantity, arrangement, and types of plants installed shall be appropriate to the size of the required landscape area and purpose of planting area as noted in Section 15.47.050 pertaining to types of landscaping.
M. 
All trash containers shall be screened from abutting properties and streets by a one hundred percent (100%) sight-obscuring fence or wall and appropriate landscaping.
