The county legislative authority or authorities shall conduct the public hearing at the date, time, and place indicated in the notice. Public hearings may be continued to other dates, times, and places specified by the county legislative authority or authorities before the adjournment of the public hearing. Each county legislative authority may alter those portions of boundaries of the proposed special district that are located within the county, but if territory is added that was not described in the original proposed boundaries, an additional hearing on the proposal shall be held with notice being published as provided in RCW 85.38.040.

After receiving the public testimony, the county legislative authority may cause an election to be held to authorize the creation of a special district if it finds:

(1) That creation of the special district will be conducive to the public health, convenience and welfare;

(2) That the creation of the special district will be of special benefit to a majority of the lands included within the special district; and

(3) That the proposed improvements are feasible and economical, and that the benefits of these improvements exceed costs for the improvements.

If the proposed special district is located within two or more counties, the county legislative authorities may cause an election to be held to authorize the creation of the special district upon making the findings set forth in subsections (1) through (3) of this section.

The county legislative authority or authorities may also choose not to allow such an election to be held by either failing to act or finding that one or more of these factors are not met.
