Iowa Code Title VIII. Transportation [Chs. 306-330B] § 306B.5. Removal after notice

1. If the owner of the advertising device or the landowner fails to act within thirty days as required in the notice, the advertising device shall be deemed to be forfeited and the department may enter upon the land and remove the advertising device. Such entry after notice, shall not be deemed a trespass and the department may be aided by injunction to abate the nuisance and to insure peaceful entry.

2. The cost of removal, including fees, costs and expenses which arise out of an action brought by the department to insure peaceful entry and removal, may be assessed against the owner of the advertising device. If the owner of the advertising device fails to pay the fees, costs, or expenses within thirty days after assessment, the department may commence an action to collect the fees, costs, or expenses, which when collected shall be paid into the “highway beautification fund”.
