When a petition is sufficient under the rules set forth in RCW 35A.01.040, calling for an election to vote upon the annexation of unincorporated territory contiguous to a code city, describing the boundaries of the area proposed to be annexed, stating the number of voters therein as nearly as may be, and signed by qualified electors resident in such territory equal in number to ten percent of the votes cast at the last state general election therein, it shall be filed with the auditor of the county in which all, or the greatest portion, of the territory is located, and a copy of the petition shall be filed with the legislative body of the code city. If the territory is located in more than a single county, the auditor of the county with whom the petition is filed shall act as the lead auditor and transmit a copy of the petition to the auditor of each other county within which a portion of the territory is located. The auditor or auditors shall examine the petition, and the auditor or lead auditor shall certify the sufficiency of the petition to the legislative authority of the code city.

If the signatures on the petition are certified as containing sufficient valid signatures, the city legislative authority shall, by resolution entered within sixty days thereafter, notify the petitioners, either by mail or by publication in the same manner notice of hearing is required by RCW 35A.14.040 to be published, of its approval or rejection of the proposed action. In approving the proposed action, the legislative body may require that there also be submitted to the electorate of the territory to be annexed, a proposition that all property within the area to be annexed shall, upon annexation, be assessed and taxed at the same rate and on the same basis as the property of such annexing city is assessed and taxed to pay for all or any portion of the then-outstanding indebtedness of the city to which said area is annexed, which indebtedness has been approved by the voters, contracted for, or incurred prior to, or existing at, the date of annexation. Only after the legislative body has completed preparation and filing of a proposed zoning regulation for the area to be annexed as provided for in RCW 35A.14.330 and 35A.14.340, the legislative body in approving the proposed action, may require that the proposed zoning regulation be simultaneously adopted upon the approval of annexation by the electorate of the area to be annexed. The approval of the legislative body shall be a condition precedent to further proceedings upon the petition. The costs of conducting the election called for in the petition shall be a charge against the city concerned. The proposition or questions provided for in this section may be submitted to the voter either separately or as a single proposition.
