Idaho Code § 43-2507
Any owner of property to be assessed in the proposed local improvement district described in the notice of intention shall have the right, in advance of the hearing, to file, in writing, a protest to the creation of the district or making any other objections in relation thereto. At the date, time and place specified in the notice of intention the board shall, in open and public session, consider all protests which have been filed in writing in advance of the hearing, and the hearing may be adjourned one (1) or more times at the discretion of the board to a fixed future time and place for the same, by publicly announcing at the hearing the continued date and time for such hearing, until all such protests have been heard. No further or additional notice of any kind shall be required. At any continued hearing, the board shall not consider any protests that were filed after the original hearing date. The decision of the board as to all protests shall be conclusive and final, and if it should so determine, the board may delete any improvements on any property which had originally been contemplated in the said notice. If owners of more than two-thirds (2/3) of the property to be assessed protest any of the proposed improvements which affect their property, the board shall not proceed further with the work so protested unless a majority of the members of the full board shall vote to proceed with such work. The vote on the hereinafter mentioned resolution creating the local improvement district shall constitute the vote as to whether or not the board will proceed. Any property owner who fails to file a protest within the time specified, or having filed one withdraws said protest, shall be deemed to have waived any objection to the creation of the local improvement district, the making of the improvements, and the inclusion of his property in the local improvement district. Such waiver shall not preclude his right to object to the amount of the assessment at the later hearing provided for such purpose.
In cases where written protests are filed and sixty percent (60%) of the owners or the owners of two-thirds (2/3) of the lots and lands within such proposed local improvement district have signed such protest, the board shall not be allowed to proceed with the creation of the local improvement district for a period of one hundred eighty (180) days.
After expiration of the one hundred eighty (180) day period, the district may recommence the initiation of a local improvement district as originally proposed or as modified as provided in this chapter.
