Property owned by the State or a unit of State government, a county, a municipality, or a regularly organized volunteer fire department that is used for public purposes is exempt from the taxes, user charges, and utility fees imposed under this part. Property that is not in a stormwater management district or is not otherwise provided direct or indirect stormwater management services in a stormwater management district may not have a tax imposed by the county until the county acquires, extends, or begins to provide stormwater management services, facilities, or programs to the property.
