Exclusion of lands

(1) (a) The boundaries of any district organized under the provisions of this article may be changed in the manner prescribed in this section, but the change of boundaries of the district shall not impair or affect its organization or its rights in or to property or any of its rights and privileges whatsoever, nor shall it affect or impair or discharge any contract, obligation, lien, or charge for or upon which it might be liable or chargeable had any such change of boundaries not been made. An election for the exclusion of real property in the district may be initiated by a petition, in writing, filed with the secretary of the board. (b) The petition shall describe the boundaries of the territory proposed for exclusion with such certainty as to enable a property owner to determine whether or not his property is within the district and shall contain a prayer for the exclusion of such territory. Such petition shall be signed by not less than fifteen percent of the taxpaying electors within the territory proposed for exclusion, and such petition must be acknowledged in the same manner that conveyances of land are required to be acknowledged. (c) If lands proposed for exclusion from a district, duly organized under the provisions of this article, are located outside the water basin or aquifer within which the district lies, as determined by the commission, such lands are eligible to be excluded under the provisions of this article and not otherwise. (d) Within twenty days after the filing of the petition, the board shall examine the petition, and, if it finds that it bears the requisite number of signatures and otherwise meets the stated requirements, it shall accept the petition and shall fix a time and place, not less than thirty days nor more than fifty days after the date of such acceptance, for a hearing thereon. The secretary of the board shall publish a notice of such hearing by one publication in a newspaper of general circulation in every county in which any portion of the district and the proposed territory for exclusion are located. Such notice shall state the nature of the petition, the description of the territories proposed for exclusion, and that any person owning any interest in real property within such territories or within the district encompassing such territories may appear at the hearing and show cause in writing why the petition should not be granted. (2) The board, at the time and place fixed, or at such times to which the hearing may be continued, shall proceed to hear the petition and all objections thereto presented in writing. The failure of any person to object in writing shall be deemed an assent on his part to the exclusion of the lands as prayed for in the petition. Upon completion of the hearing, the board may order changes in the boundaries of the lands proposed for exclusion from the district by the inclusion or exclusion of land therefrom upon finding that such change in boundaries would be hydrologically, geologically, and geographically sound. The board, in its discretion, and on conditions to be determined by the board and accepted by the petitioners, may grant the petition, deny it, or grant it as to part of the proposed exclusion of territory and deny it as to the remaining portion. (3) Any action of the board with respect to the exclusion of territory from an existing district may be reviewed by the district court in appeal proceedings filed within ten days after the board's decision has been announced. (4) If the district within which lands are excluded has incurred any prior bonded indebtedness, outstanding at the time of such exclusion, such excluded lands shall continue to be liable for the proportionate share of any such bonded indebtedness which they were under obligation to pay at the time of exclusion.
