The CH Zone shall not be applied to any land as an independent zone. Property to which the CH Zone has been applied shall be developed only in conformance with the applicable, approved project plan, subdivision, or other approved development plans. Written references to a zone that is overlain by the CH Zone, including those on the Zone Map of Provo City, shall include the underlying zone along with the acronym of the overlay zone, e.g., R110CH.
