in the same manner as provided for the organization of fire

district the property therein shall immediately become subject to

the lien for the payment of bonds theretofore authorized by the

district in the same manner as property within the district at the

time of authorization of such bonds.

Any territory adjacent to the existing district but within

another county may be included in the limits of such district by

decision of the board of directors, certified to the board of county

commissioners of both counties, with the written consent of twenty-

five percent (25%) of the holders of title to the territory sought

to be included, or in the same manner as provided for the

organization of fire protection districts. Such territory shall not

be included or added to the territory of the district without the

consent of the board of directors and the board of county

commissioners of each county. In the event such territory is

included by decision of the board of directors, with the consent of

the board of county commissioners of each county and the written

consent of twenty-five percent (25%) of the holders of title to the

territory sought to be included, the notice, hearing and order

requirements of Section 901.2 of this title and the notice and

election requirements of Sections 901.3 and 901.4 of this title

shall be followed in the same manner as for the organization of fire

protection districts. In case any such territory is added to the

district the property therein shall immediately become subject to

the lien for the payment of bonds theretofore authorized by the

district in the same manner as property within the district at the

time of authorization of such bonds.

Any landowner whose property is within the response area of the

district as assigned by the county commissioners but is not within

the fire protection district itself may elect to opt into the

district by paying the assessment to the district. The landowner

then becomes a member of the district with full voting rights.
