The A-2 zoning district is intended to provide for permanent open space and to properly guide growth of the fringe areas of the city. The A-2 district classification should be applied to property that is not intended for development, or for property that the city desires to be subject to stronger development limitations than would be provided by the A-1 district. Lands may be assigned to an A-2 district classification to:
(1) Set aside lands for open space uses, including floodways, riparian areas, steep slopes, and flood control facilities;
(2) Enhance and preserve the character of parks and other publicly owned properties;
(3) Encourage agricultural and grazing uses;
(4) Serve as a low intensity use zone.
