GSA Vice-Chair Tom Schwedhelm. “The additional meetings will provide both important information to landowners and additional feedback to the GSA Board.”
This state-mandated GSA was created to sustain the quality and quantity of groundwater in the Santa Rosa Plain (generally, the valley floor stretching from Cotati to Windsor and from the foot of Sonoma Mountain to Sebastopol). The GSA is nearing completion of a year-long study and regular public meetings to finds ways to finance day-to-day operations and groundwater planning. A groundwater sustainability fee – based on estimated groundwater use – is being considered.
“The GSA Board looked at multiple fees, rates or taxes to find an option that is fair, equitable and easy to administer. While no choice was perfect, a fee based on actual or estimated groundwater use meets all these criteria,” said GSA Board member Joe Dutton, who also served on an ad hoc committee that reviewed fee options. “To make sure that estimated groundwater use reflect what’s happening in the field, we talked to farmers and local agriculture experts and adjusted the numbers based on their feedback.”

Proposed fee amounts currently range up to $3 annually for a well owner with a small irrigation well (but whose main water supply is from a city) and up to $26 per acre foot for larger pumpers, like cities, towns, mutual water companies, agriculture and golf courses. (An acre foot of water is equivalent to 325,851 gallons.)
The proposed fee range for rural residents is up to $13 annually. ‘Rural Residential’ well owners rely solely on a well for water, and comprise an estimated 24{5fc40a96f14c4a6aa4c2a32569b0a57dcc67c0b31eb04c341474283f11b6cdd2} of groundwater use in the Santa Rosa Plain basin. The GSA is not legally permitted to (nor does it have a desire to) meter rural residential wells, so must use estimates to determine total rural residential water use.
ABOUT THE RATE AND FEE STUDY
The Sustainable Groundwater Management Act (SGMA) was passed into California law in fall 2014. The Act requires that State-designated medium and high priority basins form a GSA and develop a Groundwater Sustainability Plan (GSP). Santa Rosa Plain (essentially, the valley floor, extending from Cotati to Windsor) is a medium priority basin. In compliance with SGMA, the Santa Rosa Plain GSA was created in June, 2017.
GSA member agencies contributed funds to pay for the first two years of GSA operating costs. In fall of 2017, the GSA sought a consultant to conduct a rate and fee study to develop options for funding the agency for the next three years, until the GSP is completed (in 2022). Raftelis (a financial consulting firm) began the study in December 2017. In spring 2018, the GSA was awarded a $1 million Proposition 1 grant from the California Department of Water Resources for developing the GSP. The grant funds significantly offset GSA costs. Funding is needed to cover the remaining operating costs of approximately $337,000 annually.
Strict constitutional requirements on fees and taxes have narrowed the funding options to fees based on actual or estimated groundwater use. Potential fee payors could include groundwater users such as cities, water districts, farmers, businesses and residents with wells. It is estimated that about a third of all groundwater used in Santa Rosa Plain is used by agriculture; about a third by cities and towns; about a quarter by rural residents; with the remainder split amongst other users including mutual water companies, schools, golf courses and other commercial users.
If the GSA does not impose fees, and as a result, cannot complete and implement the GSP, the state could intervene and impose fees that would range from $100 annually for residential well owners to $300 (base fee) plus $40 per acre foot of groundwater use annually for agriculture, cities, mutual water systems, golf courses and commercial users.
