All burials shall be with the length of the casket on an east-west alignment unless the lot or parcel is not large enough to allow east-west burial, then upon application to the Sexton, such burial will be allowed to be on a north-south alignment. The Sexton shall give permission for the irregular burials only under those circumstances when the markers would be compatible with others already established in the same area. The markers for all north-south burials must be level with the ground.
