Except where otherwise expressly provided by law, the interest acquired by a condemnor under this chapter does not include the fee simple title to real property, either public or private. An interest acquired by a condemnor is not lost by the forfeiture or expiration of the condemnor's charter and is subject to an extension of the charter or the grant of a new charter without a new condemnation.
