(Ord. 12-05-001, 12-20-2005; amd. Ord. 2025-05-006, 5-22-2025)

10-8A-3: OWNER'S COMPLIANCE AFFIDAVIT; REVOCATION:

   A.   The continuation of the AG-2 and AG-3 district special use is not a matter of right but is contingent upon the annual filing of an affidavit and certification by the concentrated livestock production district owner or operator, by March 1 of each year, that it continues to meet the requirements of the district, and that the facility complies with any state laws regarding the operation of livestock management facilities, if applicable, in such form as is set out in the "county development manual" from time to time.
   B.   In the event no such annual affidavit and certification is timely filed, it shall be the duty of the zoning administrator to investigate any such AG-2 or AG-3 district. If after investigation the zoning administrator determines that the area has not been used solely for a period of one hundred eighty (180) days in the prior year as a concentrated livestock production district, said zoning administrator shall petition the zoning hearing officer to revoke the designation and to rezone the property to AG-1.
   C.   The zoning hearing officer shall thereafter provide notice of hearing and proceed in accordance with the same requirements applicable to any other map amendment.
   D.   If the county board revokes the AG-2 or AG-3 designation the zoning administrator shall remove the district and the noted public policy restrictions from the official zoning classification map within sixty (60) days from the date of the county board decision. The zoning administrator shall also notify the board of trustees of any township in which the property is located, which has established a plan commission, of any such removal within said sixty (60) day period. (Ord. 12-05-001, 12-20-2005; amd. Ord. 2025-05-006, 5-22-2025)

10-8A-4: PUBLIC POLICY:

   A.   It is hereby declared to be the public policy of the county that no new subdivisions, mobile home parks, industrial development, publicly owned recreation areas or schools shall be allowed within one-half (1/2) mile of any existing AG-2 district, or one mile of any existing AG-3 district.
      Notwithstanding the aforesaid county public policy, the zoning hearing officer may grant variations on a case by case basis from the setback requirements in existing AG-2 and AG-3 districts after a hearing and making written findings that the public interest and the interest of the livestock production facility are not adversely affected by the development of any of the aforesaid uses, and imposing on any such development conditions including waivers being obtained from any owners or subdividers thereof, binding them, and running with the land, acknowledging the inherent disadvantages involved with development in proximity to livestock production facilities and holding harmless the livestock production facility from claims and/or damages resulting from the lawful operations of the livestock production facility. In granting any such variations, the zoning hearing officer shall take into consideration such factors as prevailing winds, intervening topography, location of waste disposal facilities and any other factors which in the opinion of the zoning hearing officer is relevant to its decision.
   B.   Unless waivers have been obtained pursuant to 510 Illinois Compiled Statutes 77/35(g), no new livestock management facility will be allowed within one-half (1/2) mile of any existing municipalities, FPA, DPA, as designated on the comprehensive plan, subdivisions, publicly owned recreation areas, state or national parks or schools. Where applicable, the petitioner must also comply with any additional setback requirements set forth in 510 Illinois compiled statutes 77/35(d) and any state regulations promulgated thereunder.
   C.   No AG-2 districts existing as of the effective date of this article, that may now qualify as an AG-3 district shall be permitted to obtain an AG-3 designation in the future.
   D.   All uses in an AG-2 and AG-3 concentrated livestock production district are subject to the same performance standards and other restrictions as apply to the AG-1 agricultural district. (Ord. 12-05-001, 12-20-2005; amd. Ord. 2025-05-006, 5-22-2025)

10-8D-1: EVOLUTION OF PLAN; INTERAGENCY COOPERATION:

The comprehensive plan has identified public or private, existing or potential, areas within the county as having particular, recreational or tourism possibilities, or having special historical or archeological significance or as natural areas desirable to tie into regional recreational, historical or natural pathway goals. These areas are identified as active or special recreation (AR) areas on the comprehensive plan. Among these areas are existing golf courses and campgrounds, picnic areas, the Rock River trail, the Lincoln Highway, historic Route 2, numerous abandoned railroad rights of way and sites of historical, geological and archeological significance. It is the policy of the county to encourage the development of these areas and adjacent areas for recreational use and the promotion of tourism in the county by further identifying them and by encouraging their utilization for recreational use at the appropriate time by providing incentives and facilitations to owners of said parcels to develop them for such uses or to provide easements for such uses. The county is unable by itself to dedicate the resources necessary to accomplish these goals and when necessary will enter into intergovernmental agreements and public or private partnerships with local or regional organizations to accomplish them. These areas will be designated on the zoning maps from time to time, and subjected to special requirements in the event of their impending development. (Ord. 06-05-002, 6-21-2005; amd. Ord. 2025-05-006, 5-22-2025)

10-8D-2: DESIGNATION AND IMPLEMENTATION OF PLAN:

The planning commission at the request of the county board shall hold hearings from time to time to determine the appropriateness of designating areas as active or special recreation (AR) areas. The planning commission shall consider such questions as the public good, including benefits to tourism, additional recreational potential, accessibility to and accommodations for the public, including the disabled, costs of development, projected revenues to the county, regional benefits, impact on property in the area, any necessary intergovernmental or private agreements and any desirable zoning changes to adjacent properties. The planning commission will file written findings with the county board within sixty (60) days after the completion of the hearings. The county board may accept, modify or disregard any such findings. In the event the county board elects to proceed to designate such areas as active or special recreation (AR) areas it shall refer to the zoning hearing officer any matters requiring hearings by the zoning hearing officer under this title. The zoning hearing officer shall hold hearings in the same manner and with the same powers as it would in any special use zoning proceeding. The Zoning Hearing Officer and/or the zoning administrator are encouraged to permit variations, waivers or other modifications necessary to promote the public good in an active or special recreation designated area. Upon approval of the designation by the county board the same shall be reflected on the county zoning maps. (Ord. 06-05-002, 6-21-2005; amd. Ord. 2025-05-006, 5-22-2025)
