When a park, playground or other recreation area shall have been
shown on the plan, approval of the plan shall not constitute an acceptance
by the City of Old Town of such areas. The Board shall require the
plan to be endorsed with appropriate notes to this effect. The Board
may also require the filing of a written agreement between the applicant
and the City covering future deed and title, dedication and provision
for the cost of grading, development, equipment, and maintenance of
any such recreation area.
