This zone is intended to provide for areas of managed growth within the corporate limits of the City in which agricultural and other non-urban uses of land may continue, until such time as the City is able to provide municipal services and urban development can take place.  All lands which are hereafter voluntarily annexed by the City and which have not been designated within any zoning district shall automatically be zoned as ID until the City Council has officially acted, by their own volition or request, to place said lands within the zoning district deemed appropriate and as provided in Section 165.49(1).  Upon provision of municipal services, the City will and the property owner may initiate rezoning of property to uses consistent with the Comprehensive Plan.  ID designations on the zoning map shall be re-evaluated with each revision of the Comprehensive Plan.  ID designations shall consist of ID-RS (single-family residential) and ID-RM (multi-family residential) to reflect the intended use of the property in the future.
