Modifies provisions relating to ambulance districts

HB 2600 updates election rules for ambulance district governing boards in specific counties. It requires counties with over 105,000 residents adjacent to large charter-county areas to divide ambulance districts into six election districts with staggered terms (1-3 years), while other counties must hold at-large elections for six directors. The bill allows districts to create smaller election subdistricts (with board approval) and lets voters approve changing board size (to 7, 5, or 3 members) via ballot measure. These changes directly affect ambulance district governance structures in targeted counties, streamlining elections and board composition.
