No land shall be voluntarily dedicated for parks, playgrounds, school grounds or other public grounds, unless the public authority which is to assume the use and maintenance of such grounds shall signify its willingness to accept the same. No playground planting strip or other grounds shall be dedicated on the plat for the exclusive use of the residents in the subdivision, unless adequate provision shall be made for the maintenance thereof. Areas which are designated in the official plan as future sites for parks, playgrounds, school grounds or other public grounds, if not voluntarily dedicated for that purpose by the owner, shall be offered to the appropriate public authority having jurisdiction to acquire, develop and use land for that purpose at the time any preliminary plan or plans is submitted for subdividing of any of the tract of which it is a part. Such public authority shall have an opportunity for three (3) months after submission of the offer to submit in writing to the owner notice of its intention to acquire or purchase the desired tract. The public authority then shall have twelve (12) months after the said three (3) months within which to agree with the owner on a purchase of the desired tract or to institute proceedings to condemn said land. Nothing contained herein shall forestall approval of the submitted plan, however, the owner may not improve the area involved which is designated in the official plan as a future site for parks, playgrounds, school grounds or other public grounds during the above described effective periods of time.
