To impose a benefit charge for the construction of a water supply or sewer system, the Commission shall classify each property that abuts on a street, road, lane, alley, right–of–way, or easement in which a water main or sewer line is to be laid as: agricultural; industrial or business; institutional; multi–unit business; multi–unit residential; residential subdivision; or small acreage. The classification of a property by the Commission is final, subject only to revision: at a hearing under § 25–204(a) of this subtitle; or by the Commission if the use of the property changes.
