(a) A map or maps of the municipality and adjacent territory showing the present and proposed municipal boundaries, the present major trunk water mains and sewer interceptors and outfalls, the proposed extensions of such mains and outfalls, as required in paragraph (c), and the general land use pattern in the area to be annexed.

(b) A statement certifying that the area to be annexed meets the criteria in s. 171.043.

1. Provide for extending urban services except as otherwise provided in this subsection to the area to be annexed on the date of annexation on substantially the same basis and in the same manner as such services are provided within the rest of the municipality before annexation.

2. Provide for the extension of existing municipal water and sewer services into the area to be annexed so that, when such services are provided, property owners in the area to be annexed will be able to secure public water and sewer service according to the policies in effect in such municipality for extending water and sewer lines to individual lots or subdivisions.

3. If extension of major trunk water mains and sewer mains into the area to be annexed is necessary, set forth a proposed timetable for construction of such mains as soon as possible following the effective date of annexation.

(2) Not fewer than 15 days before commencing the annexation procedures under s. 171.0413, the governing body of the municipality shall file a copy of the feasibility study required by this section with the board of county commissioners of the county in which the municipality is located. Failure to timely file the feasibility study as required in this subsection may be the basis for a cause of action to invalidate the annexation.

(3) The governing body of the municipality shall, not less than 10 days prior to the date set for the first public hearing required by s. 171.0413(1), mail a written notice to each person who resides or owns property within the area proposed to be annexed.

A copy of the notice must be kept available for public inspection during the regular business hours of the office of the clerk of the governing body.
