Summary
Port Hueneme encourages native and drought-tolerant landscaping through California's MWELO requirements and local water conservation programs. Replacing traditional lawns with native plants is supported and may qualify for water utility rebates.
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. Local agencies are required to report on implementation annually by January 31 of each year to DWR's Water Use Efficiency Branch using the WUEdata Portal .

Full Breakdown
California's Model Water Efficient Landscape Ordinance (MWELO, Gov. Code §65591-65599) applies to new and renovated landscapes in Port Hueneme. MWELO requires a water budget approach using climate-appropriate plants. The Ventura County water agencies offer turf replacement rebates for converting grass lawns to drought-tolerant landscapes. Port Hueneme's coastal climate is well-suited to California native plants including coastal sage scrub species. Artificial turf is also an option under separate regulations.
Violations & Fines
MWELO compliance is checked during the building permit process for new landscaping projects. There are no penalties for maintaining existing lawns, but incentives encourage conversion to water-efficient landscapes.
