2. General landscape requirements.
a. Any part of the lot area not used for buildings, other structures, or for parking, loading, access ways, and other pavement areas shall be landscaped and maintained with turf, ground cover, trees, shrubs, or native planting areas.
b. Irrigation requirements.
(1) All required landscape on parcels with a commercial, industrial, and/or multi-family residential land use type must be automatically irrigated to properly establish and maintain the selected plant material with a minimum of overspray and without significant potential for causing erosion.

(3) Irrigation systems should be properly winterized prior to winter months to prevent freezing. It shall be the property owner's responsibility to properly prepare irrigation lines for months during which freezing may occur and perform testing of backflow equipment as required.
(4) Backflow equipment shall be located and/or screened in a manner that limits visibility of equipment from view of general public. Backflow equipment installed in areas with potential access by the general public should be installed in a lockable cage to prevent damage, theft, and vandalism.
c. The design standards for water discharge management contained in Section

Outside rubbish, garbage, and dumpster containers shall be permanently screened from view from all four (4) sides by an enclosure with masonry walls and a workable privacy gate or door of durable solid metal, vinyl, or wood.
