Summary

The County Layer is the regional glue: it doesn’t replace municipal governments, but it provides the services that must work across all 130 municipalities. Courts, elections, jails, public health, transit, property assessments, and regional parks—these are all county-level systems. The County Executive and Council function like a “regional mayor and legislature,” while row offices add independent accountability.
