There is hereby established for the Village, and contiguous area, an Official Map which is adopted by reference as part of these regulations. Said map is on file in the office of the Village Administrative Clerk for inspection.
A. 
Planned public improvements indicated. The Official Map may show indication of sites for planned public facilities. Public facility sites which may be indicated on the Official Map may include but are not limited to sites for new traffic ways or widening of existing traffic ways, school and recreational sites, public building sites and sites for future storm drainage, electrical or other public service or utility easements.
B. 
Planned public facilities required on subdivision plat. Whenever the Official Map indicates the necessity for providing a site for a planned public facility, the Board may require that the site for the public use be designated on the subdivision plat before granting approval to such plat; and, furthermore, that such site be held for that specific use for a period of one year from the date of record plat approval.
C. 
Responsible agency to purchase public site. Whenever a site for public use shown on the Official Map has been required to be indicated on a subdivision plat, the responsible agency having jurisdiction of such use shall acquire the land so designated or commence proceedings to acquire such land by condemnation within one year from the date of approval of such plat; and if it does not do so within such period of one year, the land so designated may then be used by the owners in any other manner consistent with this regulation and the appropriate zoning regulation.
Amendments to the Official Map, including the indication of additional public sites, shall be considered amendments to these regulations and therefore shall be as specified in § 963-23 of this chapter. Any agency requesting the establishment of the Official Map of a future public site or easement shall indicate to the Plan Commission the need for the site in the particular location specified. The Plan Commission, before making a favorable recommendation for the inclusion on the Official Map of such site to the Board, shall find that the public site location is consistent with the needs of the community and shall so indicate in its minutes.
