If notice is required under this chapter and proper notice has been given to some parties but the notice is defective or not given to other parties, the drainage authority has jurisdiction of all parties that received proper notice. The proceedings may be continued by order of the drainage authority for the time necessary to publish, post, or mail a new notice. The new notice needs only be given to those not properly notified by the first notice.
