The chapters the town posts pre-date revisions it approved in June 2023, September 2023 and February 2024, which aren't posted as clean text. Check those changes with the town.
Tables (like use tables) may not copy cleanly, so check any table against the official code.

Applicants for subdivision approval in the A-1 zone are entitled to one (1) unit per twenty (20) acres. Lots or parcels should be arranged in a manner that encourages the retention of open and usable agricultural land. Although clustering of lots is not required, if the applicant chooses not to cluster evidence and information as to why the lots or parcels will not be clustered should be provided to the Planning Commission. Lots or parcels created under the provisions of this code in the A-1 zone shall contain a minimum of twenty (20) acres. All areas not included in lots must be preserved as agricultural or open space.
Open and usable land created by the clustering of lots or parcels shall be clearly indicated on the subdivision plat and all recorded deeds of the subject property. Deed restrictions, donation of land to an approved land trust or the Town, or other development restrictions must be satisfactory to the Planning Commission and Town Board. Development on land designated as open and usable land will require, at a minimum, a plat amendment and possibly a zone change either of which may be denied by the Town.
