An important milestone for Marin’s water future: The environmental review process for the Atmospheric River Capture (ARC) Project has officially begun.🌧️
Marin Water has released the Notice of Preparation for ARC’s Environmental Impact Report, kicking off a public comment period that runs until April 13, 2026.
What is ARC? A 13-mile pipeline that would allow us to capture surplus winter water from the Russian River during atmospheric river storms and store it in Nicasio Reservoir for use during droughts—exactly the kind of infrastructure we needed during the 2021-2022 water emergency.
Why does environmental review matter? Under California law (CEQA), we must thoroughly evaluate potential impacts on wildlife, waterways, air quality, traffic, and more. This ensures responsible project development and gives the community a voice in the process.
🗣️Your input is needed. The initial scoping period is your opportunity to weigh in on what environmental issues should be studied in the EIR. Comments can be submitted by email to
[email protected] or by mail until noon on April 13.
Building water resilience requires both smart infrastructure and transparent, inclusive planning.
