Upon filing or recording of the approved final plat in the County
Clerk's office, the streets, highways, parks and drainage easements
shown thereon become part of the Official Map of the Village if such
has been adopted. However, every street, highway, park or easement
shall be deemed private until such time as it has been formally accepted
as public property by ordinance of the Village Board of Trustees,
and the responsibility for maintenance or improvement of such facilities
shall not rest with the Village until such acceptance.
