A. Landscape areas to be maintained by the city shall provide a mix of native oaks/sycamores/wildflowers/shrubs and boulder clusters installed to resemble a natural distribution blending into the surrounding area (Illustrations 5 through 7). Final plans, including irrigation system, shall be approved by the recreation and parks department. Design content shall retain natural flora and site character as much as possible.

B. Xeriscape plant selections as approved by the recreation and parks department shall be used to revegetate disturbed areas outside of lots, unless city ordinances, resolutions, or conditions of approval state otherwise.

C. Fire retardant erosion control netting or other material approved by the city recreation and parks department shall be installed as required by the city recreation and parks department to prevent erosion.

D. In order to assist in protecting slopes from soil erosion and to facilitate significant revegetation, an irrigation system approved by the public works department and recreation and parks department shall be installed on all slopes with required planting. Components and operation of the irrigation system shall be designed to maintain slope stability and integrity and provide the ability to monitor and maintain an irrigation system on a slope. In all cases, the emphasis shall be toward using plant materials that will eventually not need to be irrigated. Water and energy conservation techniques shall be utilized including, but not limited to, such items as drip irrigation and alluvial rockscape. (Ord. 4391 § 1 (Exh. A), 2006)
