Our reading is derived from what is actually built in each district today, not from the code string — a code like R-15 means different things in different Connecticut towns. It is an estimate, and the regulations linked above are the authority.
Where these names come from
Read: Town of Westport Zoning Regulations, effective April 12, 2024, on EncodePlus (https://online.encodeplus.com/regs/westport-ct/), § 4-1 Districts Established, supplemented by the table of contents and section headings for districts adopted after the § 4-1 table was last updated (§19B R-RHOW, §19C SV, §24B GBD/R, §24C GBD/SM, §29B BCRR, §36 VDO, §38, §39). §38 Aquifer Protection Overlay Zone and §39 Historic Overlay District are given no abbreviation in the ordinance, so their full names are used as the code. 10 of 13 assessor codes matched (RORD1/RORD2 = RORD #1/#2). Unmatched: AA_A and GBD/A are assessor composites with no ordinance counterpart (there is no GBD/A — only GBD/S, GBD/R, GBD/SM); MHP is most likely the assessor's shorthand for the Mobile Home Park District, but the ordinance code is MHPD, so MHP is reported unmatched rather than guessed.
