Atmospheric River Capture (ARC) Project - Information for the City of Novato

The Atmospheric River Capture (ARC) Project is a water supply resilience project designed to improve Marin Water’s reliability during dry periods. It would provide the infrastructure needed to deliver high flows from the Russian River during and following key winter storms to Nicasio Reservoir for storage, where the water can be used later during dry periods.

Why Regional Water Supply Collaboration Matters

ATMOSPHERIC RIVER CAPTURE (ARC) PROJECT Information for the Novato Community

North Bay and broader regional water systems are interconnected, and agencies regularly work together during droughts, emergencies, and other periods of urgent need to help maintain reliable water supplies.

The proposed ARC Project would strengthen regional water resilience by capturing and storing excess winter water during specific storm conditions for later use during dry periods. By storing available winter water locally during wet periods, the project can help improve drought preparedness in Marin while supporting more flexible use of shared regional water supplies during future dry conditions.

HOW IT WORKS From Storm to Storage Even in dry years with below-average rainfall, intense atmospheric river storms can temporarily swell the Russian River with high winter flows.

The ARC Project would operate during these dry year storm windows to capture and store water that would otherwise flow to the ocean.

Marin Water and neighboring agencies have a long history of working together to support regional water resilience during changing conditions, droughts and emergencies.

Winter water captured during key storm windows

PROJECT TIMELINE

The Russian River watershed is much larger than Marin Water’s Mt. Tam watershed. As a result, storms there can generate sustained runoff and elevated river flows – even in dry years – creating opportunities to capture water.

Estimated as of June 2026 and may change based on environmental review, property acquisitions and permitting.

KEY BENEFITS Improve Drought Resilience Captures excess winter water resulting from storm events, and stores it in local reservoirs for use during dry periods.

Drought Response (2021) – Residential Preparedness

During the most recent drought, Marin Water and North Marin Water District worked with the County of Marin and other partners to prepare for providing emergency potable water supplies for rural residents relying on wells that were at risk of running dry. These measures were ultimately not needed due to changing conditions.

Drought Response (2021) – Agricultural Use

Both water districts also worked with the County of Marin to support water needs in areas outside both districts’ service areas, including allowing West Marin ranchers to purchase and truck untreated reservoir water for agricultural use over several months during the drought.

Strengthen Regional Collaboration Strengthens regional water resiliency by leveraging infrastructure shared with neighboring agencies, creating opportunities for more efficient use of shared water sources and mutual aid during future dry periods.

Align with Community Priorities Marin Water is coordinating with local agencies as the project develops to identify opportunities, where feasible, to align the project with local priorities and provide added community value.

Marin Water is proposing to construct the Atmospheric River Capture Project, a water supply project designed to improve reliability during dry periods.

Because portions of the proposed project would be located in and around the Novato city limits, this fact sheet focuses on what the project could mean for the community, including potential construction impacts, proposed facilities, and upcoming opportunities for input as the environmental review process continues.

THE FULL PROJECT AT A GLANCE What Would Be Built New infrastructure would connect the North Marin Aqueduct to Nicasio Reservoir, allowing captured winter flows to be stored for use during dry periods.

Novato Landslide (2023)

A landslide in Novato raised concerns about access to local water supply. Marin Water coordinated with North Marin Water District and was prepared to support emergency interconnections if needed to help maintain service for North Marin Water District customers.

Future Opportunity – Stafford Lake Winter Water Storage

The ARC Project would include infrastructure connecting to Stafford Lake, creating a potential future opportunity for North Marin Water District to more efficiently capture and store available winter water during key storm events. By leveraging infrastructure used by both agencies, this could support additional drought resilience and more efficient use of available regional winter water sources.

Future Opportunity – Supporting North Bay Water Resilience

By allowing Marin Water to store water captured during key winter storm events for later use, the ARC Project could help reduce reliance on shared regional water supplies during droughts. This added flexibility may help support broader North Bay water resilience during periods when water supplies are limited.

*This connection to Stafford Lake creates a potential future opportunity for North Marin Water District to more efficiently capture and store available winter water during dry periods.

The full Project would include a 13.2-mile pipeline, two pumping stations, a dechlorination facility and points of delivery at both Stafford Lake and Nicasio Reservoir.

FREQUENTLY ASKED QUESTIONS Because portions of the proposed project would be located in and around the Novato city limits, these FAQs focus on what the project could mean for the community, including potential construction impacts, proposed facilities, and upcoming opportunities for input as the environmental review process continues.

Would construction near schools be addressed?

Yes. For areas near schools, such as San Marin High School, San Ramon Elementary and Pleasant Valley Elementary, construction timing would be planned to reduce potential conflicts where feasible. For example, work in these areas will be scheduled during summer months and other lower-traffic periods. Specific measures will be evaluated and refined as part of the draft EIR and in coordination with local agency partners in Novato.

What happens to roads in Novato after construction is complete?

Working with the Novato Community

Any roadway or surface disturbed during construction would be restored following completion of the work, in accordance with City of Novato requirements. Specific restoration approaches will be developed during final design and permitting, in coordination with the City. The project team will work with the City to ensure roadway conditions are restored to equal or better condition following construction.

How is Marin Water coordinating with the Novato community on this project?

Marin Water is coordinating, and will continue to coordinate, with the City of Novato, County of Marin, North Marin Water District, and other local agencies as the project is developed. This includes working together on construction planning to help minimize disruptions, as well as identifying opportunities, where feasible, to align the project with local priorities and provide added community value. As more detailed information becomes available, the District will continue to share updates and provide opportunities for public input, including during the draft EIR public review period.

Within Novato city limits, the proposed ARC Project would include approximately 3.5 miles of new pipeline, along with a pump station near Wood Hollow Drive in the San Marin area.

What to Expect in Novato What should residents expect during construction?

Construction will likely start in late 2027 - 2028. Work would move along the pipeline alignment over time, meaning impacts would be temporary and localized to specific segments rather than occurring along the full route at once.

Because much of the pipeline would be installed within existing roadways, residents may experience temporary disruptions in areas where work is active. These could include: Lane closures and traffic delays Noise and dust near active work zones Temporary parking restrictions Temporary access limitations near construction Detailed construction impacts, including traffic and noise, will be evaluated as part of the draft Environmental Impact Report (EIR).

Where would construction occur in Novato?

Within Novato city limits, the proposed ARC Project would include approximately 3.5 miles of new pipeline, which would generally be constructed within or alongside existing roadways, including San Marin Drive and a short section of Novato Blvd near San Marin High School. A new pump station would also be constructed near Wood Hollow Drive in the San Marin area. The exact pipeline alignment and construction approach are still being refined and will be evaluated as part of the draft EIR.

How would traffic and access be managed?

Maintaining access for residents, businesses, and emergency services is a key consideration of the project. While detailed traffic control plans have not yet been finalized, the project will:

About the Project

Pipeline construction would generally occur within or alongside existing roadways, including portions of San Marin Drive and Novato Boulevard.

When would it operate?

Similar to other pipeline projects, active construction would occur in segments and gradually progress along the alignment, rather than occurring along the full route at once.

Maintain vehicle access during construction, typically with work limited to a portion of the roadway (such as a single lane where feasible) Provide advance notice of temporary parking restrictions (generally at least 72 hours in advance) Ensure emergency access is maintained at all times

Where would the pump stations be located?

The project proposes two new pump stations that would operate together to move water from the existing aqueduct system to Nicasio Reservoir:

PIPELINE CONSTRUCTION WITHIN CITY OF NOVATO

Pump Station A – near Wood Hollow Drive and Redwood Blvd., close to US-101 Pump Station B – near Stafford Lake

Traffic management strategies will be further developed and evaluated as part of the EIR.

These locations are preliminary and will continue to be refined as part of the project design and environmental review process.

How long would construction take?

Pipeline construction within Novato is expected to be completed in roughly 14 to 18 months. Work would occur in segments, with active construction progressing along the pipeline alignment over time.

What would the pump stations look like?

Each pump station would include a building to house pumps, electrical equipment, and control systems.

Facilities would be designed with consideration for the surrounding area, including architectural treatments intended to be compatible with community character.

Final site layouts and designs are still being developed and will be shared with the community for input as they become available.

At a localized level, pipeline installation typically advances in segments of roughly 100 to 300 feet per day, and similar cadence would be expected for ARC, meaning construction activity in any one area would be temporary.

A more detailed construction schedule will be developed as the project design advances.

The Wood Hollow Drive (Pump Station A) site is expected to include a water storage tank. This tank would help regulate flows between the existing aqueduct system and the new pipeline. The size and configuration of the tank are still being determined and will be evaluated as part of the draft EIR.

Other than routine maintenance activities, the project would operate during dry years. These conditions generally include: Low reservoir storage levels in Marin Extended dry periods High flow in the Russian River from atmospheric river storm events When these conditions align, the project can operate during key storm windows to store water for later use.

If the project relies on rain, how could it be helpful during dry periods?

Even in dry years, historical data shows that large winter storms can still produce significant flows in the Russian River watershed, which is about 40 times larger than the watershed feeding Marin Water’s seven local reservoirs.

These flows can remain elevated for weeks or even months, and much of this water still flows to the Pacific Ocean, even after environmental requirements are met.

The ARC Project would allow Marin Water to capture a limited portion of that water during these storm windows and store it for use later during extended dry periods.

Project Status & Environmental Review What environmental studies are being conducted?

Marin Water is currently preparing a draft Environmental Impact Report (EIR) in accordance with the California Environmental Quality Act (CEQA). The draft EIR will evaluate a range of environmental topics, including: Traffic and transportation Noise Biological resources (such as wetlands and oak woodlands) Cultural and archaeological resources Air quality and other environmental factors Environmental surveys are also underway to better understand existing site conditions, including areas that may contain sensitive habitats or resources.

How will environmental impacts be addressed?

The draft EIR will identify potential environmental impacts of the project and evaluate ways to avoid, minimize or mitigate those impacts where feasible. This includes consideration of construction-related impacts as well as operational effects.

Why ARC over other options like more storage tanks, increasing reservoir capacity, etc.?

Over the last five years, Marin Water has developed and evaluated a wide range of water supply and storage options as part of its long-term planning, including reservoir expansion, the creation of new reservoirs, desalination, recycled water, direct potable reuse, bolstered demand management efforts, and increased use of supplemental Russian River supplies. Based on that evaluation, the ARC Project was identified as the most practical and cost-effective near-term option for improving long-term water supply reliability.

The ARC Project would leverage existing infrastructure to create a connecting pipeline to access and store water during key storm events for use during dry periods.

As part of the Environmental Impact Report (EIR) process now underway, a range of alternatives will continue to be formally evaluated and analyzed before any project approval is considered.

How far along is the project?

The project is currently in the environmental review phase. The public scoping period for the draft EIR has been completed, and Marin Water is preparing the draft EIR, anticipated in fall 2026. At that time, the public will have an opportunity to review the analysis and provide comments, which will be addressed in the Final EIR before project approval is considered.

Facilities would be designed with consideration for the surrounding area, including architectural treatments intended to be compatible with community character.

Final site layouts and designs are still being developed and will be shared with the community for input as they become available.

At a localized level, pipeline installation typically advances in segments of roughly 100 to 300 feet per day, and similar cadence would be expected for ARC, meaning construction activity in any one area would be temporary.

A more detailed construction schedule will be developed as the project design advances.

The Wood Hollow Drive (Pump Station A) site is expected to include a water storage tank. This tank would help regulate flows between the existing aqueduct system and the new pipeline. The size and configuration of the tank are still being determined and will be evaluated as part of the draft EIR.

Other than routine maintenance activities, the project would operate during dry years. These conditions generally include: Low reservoir storage levels in Marin Extended dry periods High flow in the Russian River from atmospheric river storm events When these conditions align, the project can operate during key storm windows to store water for later use.

If the project relies on rain, how could it be helpful during dry periods?

Even in dry years, historical data shows that large winter storms can still produce significant flows in the Russian River watershed, which is about 40 times larger than the watershed feeding Marin Water’s seven local reservoirs.

These flows can remain elevated for weeks or even months, and much of this water still flows to the Pacific Ocean, even after environmental requirements are met.

The ARC Project would allow Marin Water to capture a limited portion of that water during these storm windows and store it for use later during extended dry periods.

Project Status & Environmental Review What environmental studies are being conducted?

Marin Water is currently preparing a draft Environmental Impact Report (EIR) in accordance with the California Environmental Quality Act (CEQA). The draft EIR will evaluate a range of environmental topics, including: Traffic and transportation Noise Biological resources (such as wetlands and oak woodlands) Cultural and archaeological resources Air quality and other environmental factors Environmental surveys are also underway to better understand existing site conditions, including areas that may contain sensitive habitats or resources.

How will environmental impacts be addressed?

The draft EIR will identify potential environmental impacts of the project and evaluate ways to avoid, minimize or mitigate those impacts where feasible. This includes consideration of construction-related impacts as well as operational effects.

Why ARC over other options like more storage tanks, increasing reservoir capacity, etc.?

Over the last five years, Marin Water has developed and evaluated a wide range of water supply and storage options as part of its long-term planning, including reservoir expansion, the creation of new reservoirs, desalination, recycled water, direct potable reuse, bolstered demand management efforts, and increased use of supplemental Russian River supplies. Based on that evaluation, the ARC Project was identified as the most practical and cost-effective near-term option for improving long-term water supply reliability.

The ARC Project would leverage existing infrastructure to create a connecting pipeline to access and store water during key storm events for use during dry periods.

As part of the Environmental Impact Report (EIR) process now underway, a range of alternatives will continue to be formally evaluated and analyzed before any project approval is considered.

How far along is the project?

The project is currently in the environmental review phase. The public scoping period for the draft EIR has been completed, and Marin Water is preparing the draft EIR, anticipated in fall 2026. At that time, the public will have an opportunity to review the analysis and provide comments, which will be addressed in the Final EIR before project approval is considered.

The Atmospheric River Capture (ARC) Project is a water supply resilience project designed to improve Marin Water’s reliability during dry periods. It would provide the infrastructure needed to deliver high flows from the Russian River during and following key winter storms to Nicasio Reservoir for storage, where the water can be used later during dry periods.

Why Regional Water Supply Collaboration Matters

ATMOSPHERIC RIVER CAPTURE (ARC) PROJECT Information for the Novato Community

North Bay and broader regional water systems are interconnected, and agencies regularly work together during droughts, emergencies, and other periods of urgent need to help maintain reliable water supplies.

The proposed ARC Project would strengthen regional water resilience by capturing and storing excess winter water during specific storm conditions for later use during dry periods. By storing available winter water locally during wet periods, the project can help improve drought preparedness in Marin while supporting more flexible use of shared regional water supplies during future dry conditions.

HOW IT WORKS From Storm to Storage Even in dry years with below-average rainfall, intense atmospheric river storms can temporarily swell the Russian River with high winter flows.

The ARC Project would operate during these dry year storm windows to capture and store water that would otherwise flow to the ocean.

Marin Water and neighboring agencies have a long history of working together to support regional water resilience during changing conditions, droughts and emergencies.

Winter water captured during key storm windows

PROJECT TIMELINE

The Russian River watershed is much larger than Marin Water’s Mt. Tam watershed. As a result, storms there can generate sustained runoff and elevated river flows – even in dry years – creating opportunities to capture water.

Estimated as of June 2026 and may change based on environmental review, property acquisitions and permitting.

KEY BENEFITS Improve Drought Resilience Captures excess winter water resulting from storm events, and stores it in local reservoirs for use during dry periods.

Drought Response (2021) – Residential Preparedness

During the most recent drought, Marin Water and North Marin Water District worked with the County of Marin and other partners to prepare for providing emergency potable water supplies for rural residents relying on wells that were at risk of running dry. These measures were ultimately not needed due to changing conditions.

Drought Response (2021) – Agricultural Use

Both water districts also worked with the County of Marin to support water needs in areas outside both districts’ service areas, including allowing West Marin ranchers to purchase and truck untreated reservoir water for agricultural use over several months during the drought.

Strengthen Regional Collaboration Strengthens regional water resiliency by leveraging infrastructure shared with neighboring agencies, creating opportunities for more efficient use of shared water sources and mutual aid during future dry periods.

Align with Community Priorities Marin Water is coordinating with local agencies as the project develops to identify opportunities, where feasible, to align the project with local priorities and provide added community value.

Marin Water is proposing to construct the Atmospheric River Capture Project, a water supply project designed to improve reliability during dry periods.

Because portions of the proposed project would be located in and around the Novato city limits, this fact sheet focuses on what the project could mean for the community, including potential construction impacts, proposed facilities, and upcoming opportunities for input as the environmental review process continues.

THE FULL PROJECT AT A GLANCE What Would Be Built New infrastructure would connect the North Marin Aqueduct to Nicasio Reservoir, allowing captured winter flows to be stored for use during dry periods.

Novato Landslide (2023)

A landslide in Novato raised concerns about access to local water supply. Marin Water coordinated with North Marin Water District and was prepared to support emergency interconnections if needed to help maintain service for North Marin Water District customers.

Future Opportunity – Stafford Lake Winter Water Storage

The ARC Project would include infrastructure connecting to Stafford Lake, creating a potential future opportunity for North Marin Water District to more efficiently capture and store available winter water during key storm events. By leveraging infrastructure used by both agencies, this could support additional drought resilience and more efficient use of available regional winter water sources.

Future Opportunity – Supporting North Bay Water Resilience

By allowing Marin Water to store water captured during key winter storm events for later use, the ARC Project could help reduce reliance on shared regional water supplies during droughts. This added flexibility may help support broader North Bay water resilience during periods when water supplies are limited.

*This connection to Stafford Lake creates a potential future opportunity for North Marin Water District to more efficiently capture and store available winter water during dry periods.

The full Project would include a 13.2-mile pipeline, two pumping stations, a dechlorination facility and points of delivery at both Stafford Lake and Nicasio Reservoir.
