(1) If a resolution calling for an annexation election as provided in RCW 57.24.230 is presented for hearing, the legislative authority of each county in which the territory proposed for annexation is located shall hear the resolution or may adjourn and reconvene the hearing as deemed necessary for its purposes. The hearing, however, may not exceed four weeks in duration. Any person, firm, or corporation may appear before the legislative authority or authorities and make objections to the proposed boundary lines or to annexation of the territory described in the resolution.

(2) Upon a final hearing, each county legislative authority may make changes to the proposed boundary lines within the county as it deems proper and shall formally establish and define the boundaries. Each legislative authority also shall find whether the proposed annexation will be conducive to the public health, welfare, and convenience and whether it will be of special benefit to the land included within the boundaries of the proposed annexation. No lands that will not, in the judgment of the legislative authority, benefit by inclusion therein, may be included within the boundaries of the territory as established and defined. The legislative authority may not include within the territory proposed for annexation any territory outside of the boundary lines described in the resolution adopted by the district under RCW 57.24.230(2).

(3) Upon the entry of the findings of the final hearing, each county legislative authority, if it finds the proposed annexation satisfies the requirements of subsection (2) of this section, shall give notice of a special election to be held within the boundaries of the territory proposed for annexation for the purpose of determining whether the same shall be annexed to the district. The notice shall:

(a) Describe the boundaries established by the legislative authority;

(b) State the name of the district to which the territory is proposed to be annexed;

(c) Be published in a newspaper of general circulation in the territory proposed for annexation at least once a week for a minimum of two successive weeks prior to the election;

(d) Be posted for the same period in at least four public places within the boundaries of the territory proposed for annexation; and

(e) Designate the places within the territory proposed for annexation where the election shall be held.

(4) The proposition to the voters shall be expressed on ballots containing the words:

For Annexation to District

or

Against Annexation to District

The county legislative authority shall name the persons to act as judges at that election.
