170.15   A-P, AGRICULTURAL PRESERVATION OVERLAY DISTRICT.
1.   Statement of Intent. This District is an overlay zoning that may be used in addition to existing zoning such as A or R Districts. Its intent is threefold:
A.   To preserve agricultural use of land in areas beyond the corporate limits but which fall in the area set out in the 28E Agreement between the City of Carroll and Carroll County for zoning control.
B.   To encourage the ordered development of housing in those areas immediately adjacent to existing housing within and abutting the city.
C.   To avoid the many problems inherent in the development of 5 acre lots in areas not adjacent to current development. These problems include “hop-scotch” developments that are difficult to provide with city services as the city expands, and “land-locking” of areas resulting from development of land abutting roadways with no planned access to inner lots.
2.   Exception for existing homes. This ordinance shall have no effect on homes or platted lots in existence as of the date of enactment or the ordinance by the City of Carroll.
3.   Principal Permitted Uses. A building or premise shall be used only for the purposes designated by the underlying zoning.
4.   Special Uses. The special uses that are permitted in the A – P Overlay District shall be those allowed by, and according to the procedures provided in, the underlying zoning.
5.   Minimum Requirements.
A.   Lot size.
(1)   No lot less than 20 acres will be allowed in A-P areas zoned A1 or A2.
(2)   A-P areas also zoned R are prohibited from having lots or parcels greater than 2 acres but less than 20 acres. Minimum lot size must conform to the designated zoning.
(3)   Uses in the A-P area including commercial, public facilities, institutional facilities, group living (not including apartments), or parks that are connected and served by City of Carroll public water and sanitary sewer systems shall have no minimum lot size except as otherwise required by the underlying zoning district. This exception applies even when a property is zoned Al, A2, or R.
(Ord. 1703 - May-17 Supp.)
B.   Width requirements. No lot in any A-P area also zoned A may have road or street frontage less than 300 feet, measured at the street.
6.   Corridor Preservation. No lot in any A-P area may be platted, and no building permit shall be issued, that would deny future access to interior areas within any quarter quarter section. As a minimum, there must be left in any quarter quarter section sufficient land for a future 100-feet wide access lane or road to parcels not on street or road frontage, and no plat, survey or subdivision shall be approved which fails to preserve such a corridor of access.
7.   Off-Street Parking Requirements. Off-street parking requirements shall be as permitted by the underlying zoning.
