(a) Personal property of any kind shall not be abandoned, stored or left unattended upon project lands or waters. After a period of 24 hours, or at any time after a posted closure hour in a public use area or for the purpose of providing public safety or resource protection, unattended personal property shall be presumed to be abandoned and may be impounded and stored at a storage point designated by the District Commander, who may assess a reasonable impoundment fee. Such fee shall be paid before the impounded property is returned to its owner.

(b) Personal property placed on Federal lands or waters adjacent to a private residence, facility and/or developments of any private nature for more than 24 hours without permission of the District Commander shall be presumed to have been abandoned and, unless proven otherwise, such presumption will be sufficient to impound the property and/or issue a citation as provided for in § 327.25.

(c) The District Commander shall, by public or private sale or otherwise, dispose of all lost, abandoned or unclaimed personal property that comes into Government custody or control. However, property may not be disposed of until diligent effort has been made to find the owner, heirs, next of kin or legal representative(s). If the owner, heirs, next of kin or legal representative(s) are determined but not found, the property may not be disposed of until the expiration of 120 days after the date when notice, giving the time and place of the intended sale or other disposition, has been sent by certified or registered mail to that person at the last known address. When diligent efforts to determine the owner, heirs, next of kin or legal representative(s) are unsuccessful, the property may be disposed of without delay except that if it has a fair market value of $100 or more the property may not be disposed of until 90 days after the date it is received at the storage point designated by the District Commander. The net proceeds from the sale of property shall be conveyed into the Treasury of the United States as miscellaneous receipts.
