The water efficiency ordinance focuses on irrigation system efficiency and limiting plants requiring the most supplemental irrigation. This applies to new construction and extensive remodeling.

• Grass and flowers are limited to 50 percent or less of the irrigated area.
• Separate irrigation zones are required for grass and tree/shrub/groundcover beds. Low volume micro-irrigation is required for plant beds.
• No plant root balls or spray irrigation is permitted under roof overhangs.
• No grass should be planted in strips narrower than four feet except next to contiguous properties.
