A. 
Purpose. The Agricultural Enterprise District is intended to preserve and promote a full range of agricultural uses, secure land for livestock production and other agricultural uses that may be more intensive than crop production, strengthen agriculture's contribution to an area's economic base (including new employment opportunities), support processing, value added, and other activities closely allied to the agricultural industry, and prevent conversion of land identified as a valuable agricultural resource to uses that are not consistent with agriculture. The district's uses and regulations are designed to implement Comprehensive Plan goals by encouraging livestock and other agricultural uses in areas where conditions are best suited to these agricultural pursuits and discouraging residential development to avoid potential land use conflict. The AE District is generally compatible with the "prime agriculture" and "open space" land use designations of the Comprehensive Plan. Due to the more intensive nature of uses allowed, the AE District is not intended to be applied near moderately to densely populated areas, and it is not intended to accommodate residential uses as principle uses.

(a) 
Permits for existing livestock facilities.
[1] 
A permit is required for the expansion of a preexisting or previously approved livestock facility if the number of animal units kept at the expanded livestock facility will exceed all the following:
[a] 
The applicable size threshold for a conditional use permit established in the zoning district where the facility is located.
[b] 
The maximum number previously approved or, if no maximum number was previously approved, a number that is 20% higher than the number kept on May 1, 2006, or on the effective date of the permit requirement, whichever date is later.
[2] 
A permit is not required for a livestock facility that existed and had already been permitted by law or conditional use permit before May 1, 2006, or before the effective date of the permit requirement in this chapter except as provided in Subsection C(13)(a).
[3] 
A permit is not required for a livestock facility that was previously issued a conditional use permit or other local approval except as provided in Subsection C(13)(a). A prior approval for the construction of a livestock facility implies approval for the maximum number of animal units that the approved livestock facility was reasonably designed to house, except as otherwise clearly provided in the approval. Prior approval of a single livestock structure, such as a waste storage structure, does not constitute prior approval of an entire livestock facility.
(b) 
Application procedure. A livestock operator must complete the application and worksheets prescribed by Ch. ATCP 51, Wis. Adm. Code, including any authorized local modifications. The application requirements specified in Ch. ATCP 51, Wis. Adm. Code, are incorporated by reference, without reproducing them in full.

This notice does not constitute an approval of the proposed livestock facility.
[2] 
Within 14 days after the Town notifies an applicant that the application is complete, the Town shall notify landowners within 2,000 feet of the applicant's property. The Town shall use the approved notice form in Ch. ATCP 51, Wis. Adm. Code, and mail a written notice to each landowner.

[2] 
A permit may be denied if any of the following apply:
[a] 
The application, on its face, fails to meet the standard for approval.
[b] 
The political subdivision finds, based on other clear and convincing information in the record, that the proposed livestock facility does not comply with applicable standards in this chapter.
[c] 
Other grounds authorized by § 93.90, Wis. Stats., that warrant disapproving the proposed livestock facility.
[3] 
No conditions may be imposed on the permit other than standards provided in this chapter.
(h) 
Record of decision.
[1] 
The Town Board shall issue its decision in writing. Its decision shall be based on written findings of fact supported by evidence in the record.
[2] 
If a permit is approved, the applicant shall receive a duplicate copy of the approved application, marked "approved." The duplicate copy must include worksheets, maps, and other documents (other than engineering specifications) included in the application.

If the Town has withdrawn a local approval under this chapter, file with DATCP a copy of the final notice or order withdrawing the local approval.
(j) 
Expiration of permit. A permit remains in effect regardless of the amount of time that elapses before the livestock operator exercises the authority granted under the permit, and regardless of whether the livestock operator exercises the full authority granted by the approval. However, the Town Board may treat a permit as lapsed and withdraw the permit if the permit holder fails to do all the following within two years after issuance of permit:
[1]

Compliance monitoring. The Town Board shall monitor compliance with this chapter as follows:
[1] 
Upon notice to the livestock facility owner, the Zoning Administrator or designee may request to personally view the permitted facility at a reasonable time and date to ensure that the owner is complying with all commitments of the application as approved.
[2] 
If the livestock facility owner refuses the Zoning Administrator the right to view the permitted facility, the Zoning Administrator may obtain a special inspection warrant from the circuit court to inspect the permitted facility for the purpose of protection of the public health and safety under § 66.0119, Wis. Stats.
[3] 
If a permitted facility is found to be in violation of the commitments made in the approved application, the Zoning Administrator shall issue written notice to the livestock facility owner stating the violations and directing the owner to comply with the commitments of the approved application within a reasonable amount of time stated in this written notice.
[4] 
If noncompliance of the permit conditions as described in the written notice given by the Zoning Administrator continue past the stated reasonable time to comply, the Zoning Administrator may take further action as provided in this chapter, including but not limited to issuance of a citation or seeking injunctive relief.
[5] 
If the livestock facility owner disputes that the conditions of the permit have not been complied with, the livestock facility owner may request a hearing, in writing, within 14 days of receipt of the notice of noncompliance. The Town Board shall schedule a hearing within 30 days to determine whether violations of the permit conditions exist.
(m) 
Terms of the permit. A permit and the privileges granted by a permit issued under this chapter is conditioned on the livestock operator's compliance with the standards in this chapter, and with commitments made in the application for a permit. The Town is authorized to suspend a permit or seek other redress provided in this chapter for noncompliance.

Upon change of ownership of the livestock facility, the new owner of the facility shall file information with the Town Clerk providing pertinent information, including but not limited to such information as the name and address of the new owner and date of transfer of ownership.

The PDO Overlay District under this Zoning Code will allow for flexibility of overall development design with benefits from such design flexibility intended to be derived by both the developer and the community, while at the same time maintaining insofar as possible the land use density and other standards or use requirements set forth in the underlying basic zoning district. The unified and planned development of a site in a single or corporate ownership or control or in common ownership under the Unit Ownership Act set forth in Ch. 703, Wis. Stats. (condominiums), may be permitted by the Town upon specific petition under this section of the Zoning Code and after public hearing, with such development encompassing one or more principal uses or structures and related accessory uses or structures when all regulations and standards are set forth in this section of the Zoning Code have been met.
