Where these names come from
Read the town's own PDF, 'Zoning Regulations' (municipal-documents.s3.amazonaws.com, linked from thomastonct.gov PZC page); title page: First Adopted May 8, 1971, Revised Through May 24, 2026 (amendment #48). District list from Article 3.1 'Classification of Zoning Districts'; overlays from Article 3.3 and Article 7. The ordinance's title column names RA-80A/RA-80/RA-15 only as 'Residential'. Flood Plain, Aquifer Protection and Planned Industrial Districts are named but given no letter abbreviation in the text, so the full name is used as the code. All 6 assessor codes matched.
