How these figures were read
We found Lake County's own ordinance and had two AI models read it separately. A figure is shown only when both read the same number and the sentence it comes from was found in the document. Moratoria and bans are checked against the adopting document. Ordinances change and many figures apply only in some cases, so check the cited section with the county before relying on one.
