Modifies provisions for the county budget officer in certain first class counties

HB 3453 clarifies who serves as the county budget officer in certain counties based on their classification and population size. It specifies that in first-class counties with fewer than 100,000 residents (per the 1970 U.S. Census), the county auditor must be the chief budget officer, while other county types have designated officers (e.g., presiding commissioner in second-class counties or county clerk in third/fourth-class counties). The bill directly affects county commissions in these jurisdictions by defining their budget officer roles. This is a procedural change to administrative structure, not a new policy.
