The Landscape Documentation Package can be used for all projects, but is required for all new construction and rehabilitated projects that include landscapes greater than 5,000 square feet. The Prescriptive Compliance Option allows for a streamlined approach for new construction and rehabilitated projects that include landscapes between 500 square feet and 4,999 square feet. There are two ways to comply with WELO, depending on the size of your project. WELO provides an efficient and effective route for new construction and remodeled or rehabilitated projects. In order to comply with the State updates, Placer County’s Board of Supervisors adopted its own Water Efficient Landscape Ordinance (PDF) ( WELO) and updated Landscape Design Guidelines (PDF) in 2017.

More information on the State’s MWELO can be found at the Department of Water Resources’ website. The MWELO reduces landscape-related water use by promoting water-efficient landscapes, limiting turf, preventing waste water, and incentivizing the use of graywater and recycled water in new construction and rehabilitated projects. In 2015, the ordinance was updated by Governor Jerry Brown to further promote water conservation efforts and increase landscape irrigation efficiency. In response to the bill, the Department of Water Resources adopted the State’s Model Water Efficient Landscape Ordinance ( MWELO). In order to protect the State’s limited water resources and increase water conservation in landscaping, the state passed Assembly Bill 1881 in 2006.
