Overview
Hybrid: a Euclidean base ladder (RS/RM/CG/CH/CN/CS/P/WI/IN/LMD/GU) overlaid by a project-specific MPUD district (Article X.5) and a true form-based corridor overlay (Becker Road Overlay District / BROD, P18-024). Three structural quirks shape the code: (1) GDC legacy: PSL is one of the largest post-1960 master-planned cities in the U.S. — hundreds of thousands of quarter-acre platted lots — driving a RS-2/RS-3 dominated zoning map and GU's role as a conversion pathway; (2) RM-5/8/11/15 density-encoded multifamily is typical of FL Community Planning Act-era codes (post-1985); (3) BROD (2018) is a true Form-Based Code with build-to zones, transparency %, four Subdistricts, and explicit use prohibitions — NOT merely 'aesthetic guidance' as earlier characterized in v1 records. (4) MPUD §§158.186-158.192 is the actual codified vehicle for Tradition, Riverland, St. Lucie West and other DRI-scale master-planned communities — every project's density / mix / dimensional standards live in its adopted Regulation Book, not in base Ch. 158. | naming_convention_raw=Density-encoded multifamily: RM-5, RM-8, RM-11, RM-15 — the numeric suffix encodes maximum dwelling units per acre (5, 8, 11, 15 du/ac respectively). Single-family naming RS-2 / RS-3 is use-type-index style (lower number = larger lot: RS-2 = 10,000 sf min, RS-3 = 7,500 sf min; NOT inverse of RM density progression). Commercial districts: CG (General Commercial §158.124), CN (Neighborhood Convenience), CH (Highway Commercial), CS (Service Commercial), P (Professional §158.122). Mixed-use is Limited Mixed Use (LMD §158.155 — note: prior profile recorded this as 'LMU' which is a transcription error; the actual code abbreviation is LMD). Industrial: WI (Warehouse Industrial §158.135), IN (Industrial), with LI/HI also referenced in some city sources. GU (General Use §158.060) is a historical remnant of the 1984 Land Use Conversion Manual program. MPUD (Master Planned Unit Development §§158.186-158.192) is the project-specific PUD vehicle for Tradition / Riverland / St. Lucie West and other large master-planned communities — codified, not an overlay. ; sub_flags_raw=[live-local-active, gdc-legacy-platted-community, density-encoded-multifamily, treasure-coast-coastal-adjacent, corridor-overlay-design-only]
- Port St. Lucie is one of the largest post-1960 General Development Corporation (GDC) master-planned communities in the U.S. — hundreds of thousands of quarter-acre residential lots were platted in the 1960s–70s and sold to individual buyers nationally. This scale shapes the zoning map (dominated by RS-2 / RS-3), creates a uniquely broad absentee-owner Bert Harris exposure footprint for any down-zoning or overlay action, and drives the city's continuing population growth as platted lots fill in.
- In 1984 the city adopted a Land Use Conversion Manual to create a Bert-Harris-compliant pathway for converting GDC-platted single-family lots along major corridors to non-residential use. The General Use (GU) district is a direct remnant of this program — intended for undeveloped land where future use is uncertain. This is a zoning mechanism unique to PSL among Florida cities and is specifically a response to the GDC-platted-lot structural problem.
- Multifamily districts are density-encoded: RM-5, RM-8, RM-11, RM-15 represent maximum dwelling units per acre (5, 8, 11, 15 du/ac respectively). Typical of Florida Community Planning Act-era codes (post-1985). RM-15 at 15 du/ac is the city-wide highest residential density, which sets the Live Local Act density floor for qualifying affordable projects on commercial / industrial / mixed-use parcels.

Quirks & notes
- Port St. Lucie is one of the largest post-1960 General Development Corporation (GDC) master-planned communities in the U.S. — hundreds of thousands of quarter-acre residential lots were platted in the 1960s–70s and sold to individual buyers nationally. This scale shapes the zoning map (dominated by RS-2 / RS-3), creates a uniquely broad absentee-owner Bert Harris exposure footprint for any down-zoning or overlay action, and drives the city's continuing population growth as platted lots fill in.
- In 1984 the city adopted a Land Use Conversion Manual to create a Bert-Harris-compliant pathway for converting GDC-platted single-family lots along major corridors to non-residential use. The General Use (GU) district is a direct remnant of this program — intended for undeveloped land where future use is uncertain. This is a zoning mechanism unique to PSL among Florida cities and is specifically a response to the GDC-platted-lot structural problem.
- Multifamily districts are density-encoded: RM-5, RM-8, RM-11, RM-15 represent maximum dwelling units per acre (5, 8, 11, 15 du/ac respectively). Typical of Florida Community Planning Act-era codes (post-1985). RM-15 at 15 du/ac is the city-wide highest residential density, which sets the Live Local Act density floor for qualifying affordable projects on commercial / industrial / mixed-use parcels.
- The Becker Road Overlay District (BROD) — adopted 2018 via Ordinance P18-024, Attachment A — is a 62-page Form-Based Code (developed under a FL Department of Economic Opportunity Community Planning Technical Assistance Grant). Despite earlier characterizations of BROD as 'additive design only', it is structurally form-based: four Subdistricts (Residential, Commerce, Cross Road, Activity Center), prescriptive Building Type matrix (Table 3-1), Front Build-to Zone 25–30 ft, height cap 35 ft / 2 stories with +5 ft Activity Center bonus, transparency minimums (15% residential, 40–75% commercial ground story), and explicit use prohibitions (gas stations with fuel service, bars/lounges/night clubs, kennels w/ outdoor runs, auto/boat/farm equipment/truck sales, car washes, drive-through uses). Implements the Planning Area 4 South Neighborhood Action Plan and the 2017–2018 Comprehensive Plan amendment that converted 783 lots from RL to CL/ROI/RM/MU/OSR. PSL's post-2015 growth-management response has therefore included a real form-based corridor — not just aesthetic guidance.
- Article X.5 §§158.186–158.192 establishes a Master Planned Unit Development (MPUD) zoning district. Every large master-planned community in PSL — Tradition, Riverland, St. Lucie West, GL Homes' Riverland Center — is rezoned to MPUD, with each project's density, height, mix, and dimensional standards set by an approved MPUD Conceptual Master Plan and Regulation Book (per §158.189) rather than by base Ch. 158 standards. MPUD must be tied to an NCD (New Community Development) future land use designation and may be tied to a Development of Regional Impact. This means PSL's effective dimensional standards for half its developable land are governed by per-project Regulation Books, not by the base Euclidean ladder — a structural quirk that limits the inferential power of base RS/RM/CG zoning standards in PSL.
- PSL is coastal-adjacent but inland of the Atlantic barrier islands — Hutchinson Island / Fort Pierce / Jensen Beach front the ocean in separate jurisdictions. This means CCCL (FL Coastal Construction Control Line, c§161) generally does NOT apply to PSL parcels. However CHHA (Coastal High Hazard Area, c§163.3178) exposure IS present for portions of the city within the Category 1 SLOSH inundation zone along the North Fork St. Lucie River and eastern city edge. The distinction matters for state-preemption applicability and for FBC wind-load mapping (PSL is in Wind Zone 2/3, not Wind Zone 1 inland).
- PSL does not have a traditional downtown grid. Commercial concentrations are dispersed across planned centers (Tradition, St. Lucie West, City Center near City Hall on Walton Road). This is a structural consequence of the GDC master-plan model (no pre-existing town center) and drives the absence of a Downtown/CBD overlay in Ch. 158 — commercial-core entitlements are handled through base CG / LMU zoning rather than a formal CBD overlay.
- PSL is served by St. Lucie County Community Transit (fixed-route bus only; no heavy rail, light rail, or BRT). Nearest passenger rail is Brightline at West Palm Beach. Absence of major transit infrastructure is the direct reason there is no TOD overlay in Ch. 158. Live Local Act SB 328 (2024) parking-reduction provisions for proximity to 'major transit stops' therefore generally do NOT trigger in PSL.
- SB 328 (2024) amendments (mandatory 20% parking reduction near transit, hotel-conversion pathway, mixed-use clarification, adjacency-tempering for single-family abutters, ad valorem tax exemptions) are self-executing on application but have not been formally written into Ch. 158 LDC text in publicly accessible Municode as of April 2026. Applicants must reference both Ch. 158 and the state statute directly.
