As part of the submittal documents, the owner of the property upon which the subdivision is located shall furnish in all instances an affidavit of property owner interest stating the aggregate total area of said property and all other lands contiguous to said property in which the owner holds an interest. The applicability of the water detention requirements will be based on the total contiguous area in which an interest is held by the owner. The affidavit shall also state whether or not the owner of the subdivision had any interest at any time during the previous two (2) years. The owner shall also covenant and agree that if, within five (5) years after the issuance of a development permit, he acquires any interest in any land contiguous to the subdivision, the owner shall provide for stormwater detention for the entire aggregate area. All the above shall apply only to those subdivisions which, because of the size of their land area, are exempt from the stormwater detention requirements. (Ord. 0-77-57A, 2-9-1977)
