In laying out cemetery grounds, the corners of the subdivisions shall be indicated by substantial monuments fixed permanently in the ground as starting points for future measurements and surveys, and such monuments shall be plainly indicated on the plats of such grounds. Such plats, when completed, shall be certified by the surveyor or engineer who made the same, subscribed by the Mayor and City Clerk under the seal of the city, acknowledged before any officer authorized by law to make acknowledgment of deeds, and filed for record in the office of the County Register of Deeds. The filing of such plat shall operate as a legal vacation of any other plat of subdivisions of such grounds and of any streets, roads, or avenues passing through such grounds.
