The city may undertake any further proceedings to carry out the improvement or any extension or refinancing thereof, except that §§ 33.13 through 33.17 shall apply if additional property is included in the improvement or if change is made in the method or period of financing; but additional property may be included in the improvement with the consent of the owner thereof without compliance with other sections if it does not increase the cost apportioned to any other property, or any other change may be made without such compliance if all property owners of the improvement consent.
