Water and wastewater measures focus on increasing water efficiency in appliances in new residential development, reducing treated water used in landscaping within new residential development and at County facilities, and helping unincorporated county residents capture and utilize rainwater at home. Measures in this sector will help the County achieve reductions of 14,148 metric tons of carbon dioxide equivalent in 2020 and 17,622 in 2030.

On September 11, 2024, the Board of Supervisors adopted the 2024 Climate Action Plan . The Final 2024 CAP project documents will be posted online soon. This website will be updated to reflect the 2024 CAP. 

Strategy W-2 – Increase Rainwater Use

BACKGROUND

Climate change magnifies the frequency, severity, and length of drought conditions in our region and state. Reducing indoor and outdoor water use and capturing rainwater for irrigation results in fewer greenhouse gas emissions from the extraction, processing, and transportation of treated water.

Achievements

• Distributed an equivalent of 1,197 rain barrels in 2023 and a total of 14,125 barrels since 2014
• n 2023, the Department of Public Works’ Watershed Protection Program hosted 10 rain barrel workshops where participants were offered one free rain barrel per household and educated about how to install a rain barrel and the benefits of rainwater harvesting
• In 2020, adopted updates to the Landscaping Ordinance to achieve a 40% reduction in water use for outdoor landscaping from 2014 levels
• Adopted updates in 2020 to the County’s Water Efficient Landscape Design Manual
• Adopted updates to the Building Code in 2020 (Item 4) to improve indoor water efficiency in new residential development

Awards

• In 2022, the County received a National Association of Counties (NACo) Achievement Award (NACo Category: County Resiliency) for the Landscaping Ordinance Update. Adopted in 2020, updates to the Landscaping Ordinance reduce outdoor water use and increase residential tree planting to reduce greenhouse gases in the atmosphere, conserve natural resources and improve water quality. Implementation of the amended ordinance will reduce outdoor water use by 40% from 2014 levels and require two trees to be planted for each new single-family residence.
• The Department of Public Works’ Waterscape Rebate Program won a 2022 NACo Achievement Award (County Resiliency) for its innovative approach to stormwater management. The program, which offers rebates to residents for the installation of landscaping and water-wise features, encourages landscape upgrades like turf replacement and rain barrels on private property that help protect and filter water run-off quality. To maximize the program’s impact, the County partnered with the San Diego County Water Authority on a portion of the rebate offerings to augment benefits that also reduce water consumption and contribute to sustainability goals for the region.
• The Borrego Valley Groundwater Sustainability Plan was the first sustainability plan created in California. The Plan ensures groundwater resources can be sustainably managed and the is the first to comprehensively determine groundwater rights. The County received an Achievement Award from NACo in 2020 (NACo Category: Community & Economic Development).
• In 2019, the County developed Green Infrastructure Strategies, which provides guidance for developers of public and private design, construction and maintenance projects. The County received an Achievement Award from the National Association of Counties (NACo) in 2020 (NACo Category: Community Resilience: Infrastructure, Energy & Sustainability).
