Discussion:
HISTORY OF ITEM/BACKGROUND
The Sonoma County Flood Control and Water Conservation Act of 1949 established Sonoma Water as a Flood Control and Water Conservation District. Sonoma Water was originally authorized to provide water supply and flood control services.
In 1958, Sonoma Water formed eight geographic flood protection zones, each encompassing a major watershed. The Municipal Separate Storm Sewer System (MS4) Phase 1 Permit area encompasses the boundary of Flood Protection Zone 1A, which incorporates the Laguna-Mark West Creek Watershed. The cities of Santa Rosa, Rohnert Park, Cotati, and Sebastopol, and the Town of Windsor lie within Flood Protection Zone 1A. The MS4 Phase 2 Permit area encompasses the boundary of Flood Protection Zones 2A and 3A, which incorporates the Upper Petaluma River and Upper Sonoma Creek Watersheds. The cities of Petaluma and Sonoma, as well as the numerous unincorporated communities within these watersheds all lie within Zones 2A and 3A.
Sonoma Water is subject to requirements of the North Coast and San Francisco Bay Regional Water Quality Control Boards’ Waste Discharge Requirements (WDR) Order No. R1-2015-0050, National Pollutant Discharge Elimination System (NPDES) Permit No. CA0025054 for Discharges from the MS4 Phase 1 Permit. This five-year permit has been effective since January 6, 2016, and expired on January 5, 2021. The Phase 1 Permit has been administratively extended until a new permit is adopted. These requirements apply to Sonoma Water’s Flood Protection Zone 1A.
Because Sonoma Water owns portions of the MS4 within the Phase 1 permit boundary, Sonoma Water is a named as co-permittee along with City of Santa Rosa, County of Sonoma, City of Cloverdale, City of Cotati, City of Healdsburg, City of Rohnert Park, City of Sebastopol, City of Ukiah, and Town of Windsor. In addition, because Sonoma Water owns portions of the MS4 within the Phase 2 permit boundary, Sonoma Water is a named as co-permittee along with County of Sonoma and City of Petaluma.
As a Phase 2 co-permittee, Sonoma Water is subject to the requirements identified in the NPDES General Permit for WDRs for Storm Water Discharges from Small MS4s (Phase 2 Permit). The Phase 2 Permit went into effect July 1, 2013, and expired January 30, 2018. The Phase 2 Permit has been administratively extended until the Phase 2 Permit is renewed. Phase 2 Permit requirements apply to Sonoma Water’s Flood Protection Zones 2A and 3A.
Sonoma Water’s Storm Water Management Plan incorporates appropriate activities and best management practices for activities related to its flood control activities.
Sonoma Water is committed to protection of water quality. Under previous MS4 permits, Sonoma Water provided direct instruction to numerous students and removed debris from creeks and channels using Sonoma Water staff and through the Creek Stewardship Program (the Creek Stewardship Program is funded by Sonoma Water and City of Santa Rosa). Sonoma Water’s Water Education Program includes topics such as storm water and water conservation as part of its curriculum. Sonoma Water has partnered with the Russian River Watershed Association to administer and fund the Storm Water Pollution Prevention Video Contest for high school students. In addition, Sonoma Water’s commitment to storm water education is further demonstrated by sponsoring a school assembly program that began in 2006 to increase educational outreach that focuses specifically on storm water pollution prevention aimed at elementary and junior high school students.
