The prospect of a sprawling casino campus on Petaluma’s south side, a looming threat since the Dry Creek Band of Pomo Indians bought a 277-acre plot between Highway 101 and the Petaluma River, will remain unrealized for at least the next decade.

As part of an extension to the tribe’s 2008 agreement with Sonoma County, a prohibition of casino development near Petaluma’s Kastania Road will linger until at least the end of 2032.

The tribe, cash-strapped after agreeing to close its Geyserville casino for 2.5 months at the start of the pandemic, also secured an agreement from the county to waive its $750,000 annual payment for 2020 and 2021.
