Where the council deems it necessary, the plan shall include adjoining <br />related areas where excavations have previously been made and remain under the <br />control of the owner of the land on which the excavating is to be done or under the <br />control of the person other than the owner to whom the permit is to be issued; and <br />(11)The travel routes to and from the site. <br />(c)Operation and land rehabilitation.
