Summary
Oxnard encourages drought-tolerant and native plant landscaping through its Water Efficient Landscape Ordinance (WELO). New developments and major renovations must comply with state Model Water Efficient Landscape Ordinance standards favoring low-water-use plants.
About 40% of the water Californians use at home is used outdoors. Large water savings can be gained by efficient landscape design, installation, management, and maintenance. This is accomplished by choosing climate adapted plants, improving soil conditions, using, and maintaining high efficiency irrigation equipment and managing the irrigation schedule to fit the plants water needs as they are influenced by local climate. To increase water efficiency and better use a valuable resource, rainwater and stormwater collection and graywater and recycled water can replace or augment potable water use in landscapes.
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. Landscaping should be valued beyond the aesthetic because landscapes replace habitat lost to development and provide many other related benefits such as improvements to public health and quality of life, climate change mitigation, energy and materials conservation and increased property values.

Full Breakdown
Oxnard implements the state Model Water Efficient Landscape Ordinance (MWELO) for new construction and renovated landscapes over 500 square feet. MWELO requires a maximum applied water allowance (MAWA) that strongly favors California native and drought-adapted plants with low water needs. Landscape plans for new developments must identify plant species, irrigation systems, and water budgets. The city's coastal climate supports a wide range of native coastal sage scrub, California poppies, and salt-tolerant species suitable for Oxnard's conditions. Residents may voluntarily convert traditional lawns to native plant gardens and may qualify for rebates through local water conservation programs.
Violations & Fines
New development landscape plans that exceed MAWA water budgets will not be approved. There are no penalties for existing homeowners choosing non-native landscaping on established properties.
