Modifies provisions for local historic preservation

HB 3490 allows cities, towns, and counties to create historic preservation commissions through local ordinances. These commissions can survey historic sites, recommend landmark designations, review construction and alterations in historic areas, provide technical assistance to property owners, and develop preservation plans integrated with local planning. The bill directly affects local governments and property owners in designated historic districts by establishing formal processes for preserving historic resources. Key provisions include requiring commissions to maintain registers of landmarks, recommend preservation incentives, and review projects that impact historic integrity. The bill does not apply to college/university properties in large cities (over 400,000 residents across multiple counties).
