The petition was submitted due to drought conditions, severely low storage levels in Lake Mendocino, and a hydrologic index for establishing minimum flows not aligning with the watershed conditions. On January 1, 2021, the water supply condition for the Russian River was reclassified as 'Normal' from 'Dry' based on the cumulative inflow into Lake Pillsbury for the water year. The calculated cumulative inflow of 9,539 acre-feet exceeded the threshold criterion of 8,000 acre-feet between the two classifications. This designation of 'Normal' water supply conditions does not accurately reflect the current watershed conditions and the lack of rainfall experienced in 2020 in the Upper Russian River. As measured at Ukiah, recorded rainfall for 2020 was 11.32 inches, which amounts to 31% of the average rainfall (37.01 inches). This was the second lowest rainfall recorded since 1893.

Project Location: Located near the intersection of Sonoma Avenue and E Street, Santa Rosa, Sonoma County.
Project Description: An existing section of the Santa Rosa Creek Aqueduct crosses under Santa Rosa Creek and is at risk of failure during an earthquake due to liquefaction and lateral spread. The proposed project would help to reduce failure of this section of the Santa Rosa Aqueduct due to earthquake-induced liquefaction and lateral spread by relocating a section of pipeline (approx. 730 ft.) from the existing stream crossing to a location downstream under E Street and Sonoma Avenue. The relocated pipeline would use a trench-less technology to tunnel under the existing E Street Bridge and concrete box culvert into which the creek currently flows. The expected result is that the project would eliminate the Santa Rosa Aqueduct’s exposure to the free face of the creek and would help to reduce the risk of failure due to earthquake-induced liquefaction and lateral spread hazard at the existing pipeline stream crossing.

Project Location: The Airport/Larkfield/Wikiup Sanitation Zone (ALWSZ) treatment, storage, and disposal facilities in the unincorporated area northwest of Santa Rosa and the treatment, storage, and disposal facilities in the Town of Windsor and surrounding unincorporated area.
Project Description: The project comprises an agreement (Agreement) that will allow the ability to transfer recycled water and partially treated wastewater between the ALWSZ and the Town of Windsor treatment, storage, and irrigation facilities. The Agreement will allow for the coordinated operation of these systems for the purposes of increasing operating efficiencies, reducing operational costs, increasing beneficial use of recycled water, and decreasing discharges of recycled water to Mark West Creek, for an initial term of five years. The project may include the modification or installation of valves to existing wastewater and recycled water pipelines that will not result in an expansion of use. All project modifications will be conducted in existing roadways and within the footprint of the sanitation districts' existing facilities.
