Rainy Day Fund
A reserve fund set aside specifically for emergencies, revenue shortfalls, or unexpected expenses — separate from the general fund balance.
How It Works
Also called a budget stabilization fund, the rainy day fund provides an additional layer of financial resilience beyond the general fund balance. Some cities have formal policies requiring deposits during good revenue years and restricting withdrawals to defined emergency conditions. Well-managed rainy day funds helped cities weather the 2008 recession and the 2020 pandemic with fewer service cuts.
