Overview
Traditional Euclidean district-and-overlay code under Ch. 656 of the Jacksonville Ordinance Code. Consolidated city-county jurisdiction (Duval County-wide except 4 beach/rural municipalities). Unique lot-size-encoding convention in RLD series (numeric suffix encodes frontage width, lot area follows pattern). Three form-sensitive historic/design overlays (San Marco, Riverside Avondale, Riverside Avondale Historic) plus AICUZ military overlays at NAS Jacksonville and NS Mayport. | naming_convention_raw=abbreviation-encoded with lot-width numeric suffix for RLD series (RLD-60 = 60 ft min width + 6,000 sf min lot); RMD letter-suffixed (A/B/C/D/MH) by density tier; RHD letter-suffixed (A/B) for high density; C*, I*, PBF*, PUD* for commercial/industrial/public/planned ; sub_flags_raw=[consolidated-city-county, coastal-fl, live-local-active, aicuz-military, large-jurisdiction]
- Largest U.S. city by land area (874 sq mi); consolidated city-county jurisdiction covers essentially all of Duval County.
- RLD-series lot-size encoding: numeric suffix = minimum lot width in feet; lot area follows (RLD-60 = 60 ft width + 6,000 sf lot). Unusual mnemonic convention among top-100 U.S. cities.
- RLD-TND (Traditional Neighborhood Development) requires alley access or detached garage behind primary home; highest lot coverage (65%) in the RLD series; ADU by right — traditional-urban form standard encoded in a low-density residential category.

Overlays
Mapped boundary around San Marco Square and the San Marco commercial corridor (Hendricks Ave / San Marco Blvd / Atlantic Blvd) in Council District 5. Overlay geometry appears on the Jacksonville zoning atlas (maps.coj.net/zoning) and in the Planning and Development Department overlay exhibit.
Mapped boundary covering Riverside, Avondale, and Murray Hill segments west of the St. Johns River in Council District 14; boundary appears on the Jacksonville zoning atlas overlay layer and RAZO exhibit.
Mapped boundary covering the locally designated Riverside Avondale Historic District; substantially overlaps the RAZO overlay footprint west of the St. Johns River. National Register nomination boundary is substantially coincident.

Quirks & notes
- Largest U.S. city by land area (874 sq mi); consolidated city-county jurisdiction covers essentially all of Duval County.
- RLD-series lot-size encoding: numeric suffix = minimum lot width in feet; lot area follows (RLD-60 = 60 ft width + 6,000 sf lot). Unusual mnemonic convention among top-100 U.S. cities.
- RLD-TND (Traditional Neighborhood Development) requires alley access or detached garage behind primary home; highest lot coverage (65%) in the RLD series; ADU by right — traditional-urban form standard encoded in a low-density residential category.
- RLD-TNH (Townhouse) has a 15 ft minimum frontage (25 ft end unit) — extremely narrow lot widths for attached townhouses.
- RMD-B/C/D density is a sliding formula (base lot area for first 2 units + per-unit addition), not a straight DU/ac cap; both the formula AND the DU/ac cap must be satisfied.
- NAS Jacksonville + NS Mayport AICUZ: military-installation noise and accident-potential zone overlays exempt LLA qualifying projects within 1/4 mile of installation boundary from automatic administrative approval.
- Three Council-designated historic/character overlays (San Marco, Riverside Avondale Zoning, Riverside Avondale Historic) cover the city's three pre-war streetcar neighborhood cores.
- Downtown Overlay (CCG-1 context) has substantially taller height envelope than outlying CCG nodes — material to Live Local Act height-floor calculations in the 1-mile test.
