Flood Zones 2A and 3A Natural Channels Maintenance Project
A flood control maintenance project is being proposed by the Sonoma County Water Agency to reduce flood risk and avoid erosion on creeks and channels in the Petaluma Valley and Upper Sonoma Creek watersheds. The project would be implemented mainly on private property at a landowners’ request when a creek blockage is causing — or is likely to cause — bank erosion. The project would allow for small-scale maintenance activities in the Petaluma and Sonoma areas that are within the boundaries of Flood Control Zones 2A and 3A.
This project would allow the Water Agency to respond to landowner requests if no endangered or threatened species or their habitat are present; the project simply involves the removal of debris or a blockage that could lead to flooding or erosion; and is limited to minor bank repairs to address erosion using biotechnical erosion, which uses vegetation and natural structural materials, such as boulders and root wads.
The Water Agency has prepared an Initial Study and Negative Declaration of Environmental Impact (IS/ND) for the project in accordance with the California Environmental Quality Act. The Public Comment period for the IS/ND opened on December 23, 2015 and will close on January 27, 2016. The documents are available below:

Dry Creek Habitat Enhancement Project, Miles 2-6 - Draft Environmental Impact Report
The Sonoma County Water Agency (Water Agency), as Lead Agency, has prepared this Draft Environmental Impact Report (EIR) for Dry Creek Habitat Enhancement Project, Miles 2–6 (proposed project) to provide the public and responsible and trustee agencies reviewing the Dry Creek Habitat Enhancement Project an analysis of the potential effects, both beneficial and adverse, on the environment.1 This project is intended to fulfill federal mandates to implement habitat enhancement within Dry Creek to create both winter and summer rearing habitats for juvenile steelhead and coho salmon, with an emphasis on improving habitats for the survival of juvenile coho salmon while allowing the Water Agency to maintain the existing flow range in Dry Creek for water supply purposes.
Russian River - Cotati Intertie Pipeline Seismic Hazard Mitigation
The Water Agency owns, operates, and maintains a 48-inch diameter steel water supply pipeline (referred to as the Russian River-Cotati Intertie) that crosses the southern and eastern aqueduct transmission lines and crosses the Russian River in Sonoma County. The pipeline is buried at a relatively shallow depth (approximately 7 feet below ground surface) across the Russian River channel and stream banks, and crosses seismically unstable terrain.
The Local Hazard Mitigation Plan (LHMP) identifies the Russian River-Cotati Intertie Intertie crossing of the Russian River as vulnerable to potential ground deformation, liquefaction, and lateral spread resulting from strong ground shaking in the soil at or below the elevation of the pipeline. The LHMP states that pipeline failure from an earthquake would isolate the Mirabel collector wells from the Russian River-Cotati Intertie Intertie Pipeline.
The proposed project is needed to address seismic concerns related to reliable delivery of water to the Water Agency’s service area and prevent the loss of an essential water service due to a moderate or severe earthquake along the Rodger's Creek/Hayward Fault.
