Water and sewer bills in Grover Beach could increase by nearly 20% to make up for a $2 million deficit in revenue, the city announced Wednesday in a news release. At its Sept. 5 meeting, the Grover Beach City Council learned about the findings from a recent utility rate study, heard recommendations and unanimously instructed the city staff to start the Proposition 218 process, a step in notifying the public about proposed rate changes, the release said. Prior to the 2023 study, the city conducted rate studies approximately every five years, with one conducted in 2021.
