  • The city code page lists a zoning regulations chapter (165) and an establishment of districts chapter (166) as code supporting documents.
  • The chapter PDFs could not be text-extracted by the open-page tool, so the operative zoning text, use table and procedures were not read.
  • The homepage lists subdivision regulations as ch 169 while the code page lists chapter 170; treated as a navigation discrepancy, not a finding.
  • September and October 2025 council agenda items show first readings of zoning amendments (planning and zoning commission membership, variances, rebuilding after destruction, accessory dwelling units); adoption of these was not confirmed.
