Ahead of the planned restart of negotiations and public outreach over the future of the Sonoma-Marin Fairgrounds, Petaluma officials have asked the fair operator to lay bare the agency’s books, requesting everything from master facilities lists and employee rosters to prospective plans for a smaller fair footprint.

The letter, sent July 21 by Petaluma City Manager Peggy Flynn, serves as the city’s first official response to a scathing March 18 missive from the 4th District Agricultural Association, which has sought to extend its 50-year lease of the city-owned fairgrounds property past Dec. 31, 2023.
