In any area designated as a cremation area, the cremated remains of two persons may be placed in one adult gravesite; or, the cremated remains of one person can be placed in the same adult gravesite where a casket burial has taken place or is contemplated to take place; provided, however, that in each of these cases only one grave marker shall be allowed for such a grave. Double depth graves are permitted; provided, the proper liner or vault devices are utilized. (Ord. 81-25 §5, 1981; Ord. A-584 §10, 1965).
