The LA Safe Clean Water Program received approximately $95 million in disbursements this year, funding stormwater capture and green infrastructure across Los Angeles County.
The LA Safe Clean Water Program is financed through Measure W, a parcel tax approved by voters in 2018, which generates approximately $280 million annually. The program supports stormwater capture, water quality improvements, park creation, and community engagement across nine watershed areas. Seven years into implementation, critics and supporters alike agree progress is real, but insufficient given mounting climate pressures.
Funding is split across three streams: 50% for regional multi-benefit infrastructure, 40% for municipal programs, and 10% for district operations and maintenance. The structure is designed to balance the impact on large-scale watersheds with local control. According to November 2025 implementation updates from Los Angeles County, approximately $95 million was distributed during the fiscal year.
The Upper Los Angeles River watershed received the largest annual allocation at $38.3 million, followed by South Santa Monica Bay at $17.4 million and Central Santa Monica Bay at $17.1 million. Smaller watersheds such as North Santa Monica Bay received less than $2 million. The LA Safe Clean Water Program emphasizes nature-based solutions, including rain gardens, bioswales, green streets, wetland park conversions, and subsurface infiltration systems.
The central question remains whether these projects materially improve the water supply. Los Angeles currently imports roughly 85-90% of its water from Northern California and the Colorado River. The city’s climate strategy aims to source 70% locally by 2035, yet stormwater capture currently provides only a modest share of the total supply.
Los Angeles County allows more than 100 billion gallons of stormwater to flow untreated into the ocean each year. Program goals aim to increase capture from about 24 billion gallons annually to 49 billion gallons by 2035. Even if achieved, more than half of the potential stormwater would remain uncaptured.
Existing projects under the program collectively generate an estimated 56,915 acre-feet of average annual capture, equivalent to roughly 18.5 billion gallons. To meet stated goals, that amount would need to more than double within the next decade.
Environmental advocates argue implementation is too slow. Groups, including the Natural Resources Defense Council (NRDC), Heal the Bay, and LA Waterkeeper, have called for accelerated timelines and stronger accountability through the Vision 2045 framework, citing climate risks and ongoing water quality violations in frontline communities.
More than 700 projects are currently in various planning and implementation stages. In the program’s first four years, only 126 regional projects received funding. The OurWaterLA coalition supported just 31 of those, citing stronger alignment with nature-based and equity-centered design, which is less than one-quarter of funded regional projects.
Equity remains a persistent challenge. Los Angeles County comprises 228 water utilities and 182 agencies responsible for managing surface water, groundwater, and flood control, resulting in fragmented governance. Many low-income communities and communities of color still lack consistent access to clean, affordable drinking water.
Research from the University of California, Los Angeles (UCLA) Luskin Center analyzed the 116 projects under the LA Safe Clean Water Program and found significant room for improvement in delivering measurable community benefits to disadvantaged areas. The study recommends stronger performance metrics and long-term accountability mechanisms.
Cost-effectiveness also varies widely. The Hollenbeck Park Lake Rehabilitation Project received $25.2 million in funding and is expected to capture 347.7 acre-feet annually, roughly $72,500 per acre-foot of annual capture. Whether that represents good value depends on comparisons to alternatives such as recycled water, conservation, or efficiency programs, as well as how additional benefits like park access and water quality are valued.
Supporters argue that stormwater capture remains essential for long-term resilience. Traditional flood-control infrastructure prioritized rapid runoff to the ocean, worsening pollution and wasting water. Shifting toward capture and reuse aligns with climate adaptation goals, even if implementation is slow.
Seven years in, the LA Safe Clean Water Program demonstrates both promise and limitations. Funding is stable, community partnerships are expanding, and measurable improvements in water quality have been achieved. But scaling fast enough and equitably enough remains the program’s defining challenge as climate risks intensify.
