Document Description
The Sonoma County Water Agency (Sonoma Water) is the project proponent and lead agency in accordance with the California Environmental Quality Act (CEQA) for the proposed Vortex Tube Rehabilitation Project (Proposed Project), which is a flood control structure repair project. Sonoma Water staff has prepared this Draft Initial Study and Mitigated Negative Declaration of Environmental Impact (Draft IS/MND) to provide decision makers, the public, responsible agencies, and trustee agencies with information about the potential environmental impacts associated with the construction, maintenance, and operation of the Proposed Project. This Draft IS/MND was prepared pursuant to the requirements of CEQA (California Public Resources Code Sections 21000 et seq.), State CEQA Guidelines (Code of Regulations, Title 14, Division 6, Chapter 3), and Sonoma Water’s Procedures for the Implementation of CEQA. After completion of the public review period for this document, this Draft IS/MND, along with a summary of comments submitted and response, will be brought before Sonoma Water’s Board of Directors for their consideration.
The Vortex Tube is part of the Santa Rosa Creek Diversion Structure flood control facility, located beneath Montgomery Drive, near Spring Lake and the City of Santa Rosa. The Vortex Tube has deteriorated from over a half-century of scour. The Proposed Project would restore the structural integrity of the Vortex Tube and facilitate future inspections and maintenance.
