The amount of assessment attributable to property or a business owned by the same property or business owner that is in excess of 40 percent of the amount of all assessments proposed to be levied, shall not be included in determining whether the petition is signed by property or business owners who will pay more than 50 percent of the total amount of assessments proposed to be levied.
