17.1.1 Examples of Applications. ¶
17.1.1.1 Example 1. A 180 acre tract of land is designated by the plan Agriculture Exclusive, with a planned density of one dwelling unit per 60 acres. If the zoning is AEB7 (10), subdivision could take place creating two 10 acre parcels and one 160 acre parcel. Such an action would require a rezone on the remainder parcel (in this case 160 acres) to prevent further subdivision in conflict with the density in the General Plan. The remaining 160 acre parcel would be rezoned to B7 (160). (Former Section INL#315-2)

17.1.1.2 Example 2. Same as Example 1, except only one 10 acre parcel is created. The Remaining 170 acre parcel could still be split two ways. Depending on the particular circumstances, a rezone, recorded map note, or other enforceable restriction might be appropriate. (Former Section INL#315-2)
180 Acres
==> picture [255 x 160] intentionally omitted <==
17.1.1.3 Example 3. A 120 acre parcel has a General Plan designation of 20 acres per dwelling unit. 120 divided by 20 equals six parcels available. With a AEB7(2 1/2) zoning, two 1/2 acre parcels, one 5, one 20, and two 45 acre parcels could be created. Rezoning to the appropriate B7 parcel size designation would be necessary: B7(2 1/2), B7(5), B7(20), and B7(45), respectively. (Former Section INL#315-2)
