Title

Sonoma Aqueduct Creek Crossings Vegetation Management Project (Project)

Description

The Sonoma Aqueduct (Aqueduct) is the primary source of drinking water for customers of the Valley of the Moon Water District and City of Sonoma. Sonoma Water maintains a facility easement along the approximately 16-mile long Aqueduct pipeline. Though mostly underground, the Aqueduct includes aboveground sections at the three channel crossing sites (described above) that are susceptible to damage by falling trees. Failure of the Aqueduct would be of critical public health and safety concern. This project would manage existing trees within the easement that could potentially damage the Aqueduct due to their proximity, size and flammability. The project would include the removal and pruning of up to 20 native trees (alder, ash, bay, box eIder, oak, willow) ranging in size from approximately 4- to 30-inch diameter at breast height (DBH) and 5 non-native eucalyptus trees ranging in size from approximately 30- to 60-inch DBH. Follow-up vegetation management, as well as the removal of downed wooy material, would be conducted as needed to maintain access and clearance. No heavy equipment would would enter the active channel. Tree stumps and root structures would be left in place to avoid ground disturbance. Cut stumps may be treated with herbicide approved for use near water to prevent regrowth. Cut material would be mulched onsite or hauled offsite.
