Farms
Only for the principal residential structure: A property that has an agricultural use assessment as determined by the Maryland State Department of Assessments and Taxation shall be subject to a CWAF, including both the Administrative and Impervious Area Fee, based on the impervious area measurement only for the principal residential structure located on the property. The portion of the land under agricultural use for agricultural purposes will not be charged a CWAF.
