Summary
The City of Orange encourages native and drought-tolerant plant landscaping through its water conservation program and landscape standards. New landscaping over 500 square feet must comply with the city's Landscape Standards and state water conservation laws.
New development and retrofitted landscape water efficiency standards are governed by the Model Water Efficient Landscape Ordinance (MWELO). The MWELO is also referenced by Title 24, Part 11, Chapters 4 and 5 CalGreen Building Code. All local agencies must adopt, implement, and enforce the MWELO or a local Water Efficient Landscape Ordinance (WELO) that is at least as effective as the MWELO. Usually, local agencies that adopt WELOs create a more stringent ordinance than MWELO. The purpose of water efficient landscape ordinances is to not only increase water efficiency but to improve environmental conditions in the built environment.

Under the city's Landscape Standards and Specifications (Section IX), new landscape installations exceeding 500 square feet must comply with state and local water conservation requirements including the Model Water Efficient Landscape Ordinance (MWELO). Native California plants are encouraged as they require less water and maintenance. The city's approved plant list includes species adapted to the Southern California climate. Fire-resistant native plantings are recommended in areas near the Santiago Hills wildland-urban interface. The Community Services Department provides guidance on appropriate native plant selections for residential landscaping.
Violations & Fines
