The zoning districts and Zoning Overlay District established in § 175-5 above herein are to be shown on a parcel base map of the Village of Phelps that has been prepared by the Ontario County Department of Planning and based upon records from the Ontario County Office of Real Property, adopted by Village Board Resolution and certified accurate by the Village Clerk as of a certain date. Said map shall then be known as the "Official Zoning Map" for the Village of Phelps. Each subsequent rezoning of land authorized by the Village Board shall be documented upon the Official Zoning Map and upon certification by the Village Clerk, the Official Zoning Map shall be amended. No amendment to this Official Zoning Map which portrays matters affecting the zoning designation of land on the map shall become effective until such change and entry has been made on said Zoning Map and has been attested to by the Village Clerk. All Zoning Map changes shall be made within 15 business days from Village Board action to approve.[1]
