All granite monuments shall be 4 feet long and 6 inches above ground, except in lawns, driveways and parking lots, where they shall be flush. If the subsurface is a ledge between 1 and 3 feet deep, a 2_foot diameter concrete encasement based on the ledge shall be required. If the
ledge is less than 1 foot deep, a 1-inch steel rod shall be grouted into the ledge.
(2) (b) All other corners shall be marked with iron pipe not less than 3/4 inch in diameter and 24 inches long and driven so as to be flush with the finished grade.
