Iowa Code Title XI. Natural Resources [Chs. 455-485] § 468.622. Drainage connection with highway

1. When the course of natural drainage of any land runs to a public highway, the owner of such land shall have the right to enter upon the highway for the purpose of connecting the owner's drain or ditch with any drain or ditch constructed along or across the highway. In making the connections, the owner shall do so in accordance with specifications furnished by the highway authorities having jurisdiction over the highway, which specifications shall be furnished to the owner on application. The owner shall leave the highway in as good condition in every way as it was before the work was done.

2. If a tile line or drainage ditch must be projected across the right-of-way to a suitable outlet, the expense of both material and labor used in installing the tile line or drainage ditch across the highway and any subsequent repair of the tile line or drainage ditch shall be paid from funds available for the highways affected.
