No person shall move any building, house or portion thereof without notifying the director in advance of such moving. Said notice shall designate the route to be followed and all other details pertinent to such work. The director shall have the authority to change such route and designate one which in his opinion will cause less damage to trees owned by the city along and adjacent to said route. If necessary to protect such trees, the director may require that said house, building or portions thereof to be cut into segments small enough to fit the available width between such trees along the designated route. As a condition to approving any route for the moving of any building, house or portion thereof, the director may require the person doing such work to enter into an agreement to pay all costs incurred for any labor, equipment or material used to protect or preserve such trees either before or after such moving. (Ord. 428, 12-17-1968)
