(b) The report required in subsection (a) of this Code section shall include:

(1) A map or maps of the municipal corporation and adjacent territory, showing the present and proposed boundaries of the municipal corporation, the present major trunk water mains and sewer interceptors and outfalls, the proposed extensions of such mains and outfalls as required in paragraph (3) of this subsection, and the general land use pattern in the area to be annexed;

(2) A statement showing that the area to be annexed meets the requirements of Code Section 36-36-54; and

(c) The plans required in subsection (a) of this Code section shall:

If a water distribution system is not available in the area to be annexed, the plans must call for reasonable, effective fire protection services until such time as water lines are made available in such area under existing municipal policies for the extension of water lines;

(2) Provide for extension of major trunk water mains and sewer outfall lines into the area to be annexed so that when such lines are constructed 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 outfall lines into the area to be annexed is necessary, set forth a proposed timetable for construction of such mains and outfalls as soon as possible following the effective date of annexation. In any event, the plans shall call for contracts to be let and construction to begin within 18 months following the effective date of annexation; and

(4) Set forth the methods under which the municipal corporation plans to finance extension of services into the area to be annexed.
