A tax imposed pursuant to this article is a special tax and not a special assessment, and there is no requirement that the tax be apportioned on the basis of benefit to any property. However, a special tax levied pursuant to this article may be on or based on benefit received by parcels of real property, the cost of making facilities or authorized services available to each parcel, or other reasonable basis as determined by the city, county, city or county, or library district. A special tax apportioned on any of these bases shall not be construed to be on or based upon the ownership of real property.
