16.20.140   Landscaping--Minimum requirements.
   Landscaping shall be designed to screen the perimeter of oil operations sites and create buffers between oil field facilities and urban uses. Landscaping shall implement the Landscape Design Guidelines for the Willow/Spring/Cherry Corridors on file in the community development department and be arranged to improve the visual appearance of oil field activities and to mitigate the impact of oil-related activities on urban development while still allowing normal oil recovery operations. Recognizing variations in oil well locations, pumping units, concrete pads, pipes, and other potential obstructions and the need, in some cases, for unobstructed access to operations, the following minimum landscaping standards shall apply:
   A.   Four fifteen gallon size trees and six five gallon size shrubs shall be provided for each oil well.
   B.   Four fifteen gallon size trees and six five gallon size shrubs shall be provided for each tank.
   C.   Automatic irrigation systems or other provisions for regular watering shall be provided. The use of drought tolerant trees and shrubs is recommended.
   D.   All landscaping and irrigation shall be properly maintained in accordance with an approved landscaping plan and maintenance agreement.
   E.   It shall be the responsibility of the inspector to inspect landscaping and order the operator to repair, prune, or replant as necessary to maintain a high quality standard of landscaping appearance. When necessary, the inspector shall enforce the landscape plan and maintenance agreement.
