Idaho Code § 43-1121
Prior to construction of a distribution system under the authority of either section 43-329 or 43-333, Idaho Code, or under any law authorizing a local improvement district, an irrigation district shall mail a notice of the intended construction to the current owner of any lot or parcel within the area to which irrigation water can be delivered by that distribution system, which previously had been excluded from the district as not agricultural. The notice shall state that the lot or parcel may be eligible for reinstatement, with water rights, if the owner so requests in writing, properly signed and acknowledged, and shall specify the date, not less than three (3) weeks after mailing of the notice, after which the irrigation district may decline to consider the request.
