Port St. Lucie, Florida: City Guide

Port St. Lucie is a city of 120 square miles in St. Lucie County on Florida's east coast, about 50 miles north of West Palm Beach.

The City of Port St. Lucie states that it was incorporated on April 27, 1961 and occupies 120 square miles in St. Lucie County, and it places the city about 50 miles north of West Palm Beach, halfway between Miami and Orlando (City of Port St. Lucie About page). City Hall sits at 121 SW Port St. Lucie Blvd. in ZIP code 34984, and the city's main phone line, 772-871-1775, is printed in the footer of the city About page. The same About page describes Port St. Lucie as the largest city between Orlando and Miami.

The city reaches across Interstate 95. The planning department's FAQ lists the properties west of I-95, including Tradition, Southern Grove, Western Grove, Riverland and Wilson Groves, among the areas outside the original platted city (Port St. Lucie growth and development FAQ).

St. Lucie County runs countywide services that Port St. Lucie residents also use, such as the Alert St. Lucie notification system and the county shelter and evacuation program (St. Lucie County Emergency Preparedness Portal). The Port St. Lucie government and utilities sections explain which office handles each service.

The Census Bureau's ACS 2020-2024 5-year estimates count 232,491 people in Port St. Lucie, with a median age of 43.9 (ACS DP05 for Port St. Lucie city).

The city publishes larger and smaller numbers of its own, and the official figures do not agree. The About page opens with more than 260,000 residents, while its Population and Location tab cites a 2020 Census Bureau estimate of over 204,851 residents (About PSL). The planning department's FAQ says Port St. Lucie grew from less than 300 people in 1961 to over 260,000 in 2025 (growth and development FAQ). The ACS figure is a 2020-2024 5-year estimate, and the table below lists it beside the other ACS measures for the city.

In that survey, 21.8% of Port St. Lucie residents were 65 or older (DP05). Median household income was $80,648 and the mean commute was 30.5 minutes (ACS DP03 for Port St. Lucie city). The ACS counted 90,911 housing units, 83,952 of them occupied; owners held 84.0% of occupied homes, the median owner-occupied value was $369,200 and median gross rent was $1,937 (ACS DP04 for Port St. Lucie city). Last verified: October 22, 2026, with the Port St. Lucie population figures re-read from the three ACS 2020-2024 tables, the city About page and the planning FAQ.

Port St. Lucie began in 1961 as a city incorporated by a development group selling quarter-acre lots to retirees, on land its developer had platted mostly into single-family lots.

The city's own history page says Port St. Lucie was incorporated in 1961 by a development group with a goal to sell quarter-acre lots to retirees, and that it was formed without sidewalks, streetlights, water and sewer (City of Port St. Lucie history story). The same page notes that, unlike neighboring cities, Port St. Lucie has no historic downtown built near the old Flagler railroad stops.

The planning department fills in the developer and the timeline. General Development Corporation (GDC) developed 66 square miles into primarily single-family lots with minimal infrastructure such as roads and drainage, which is why the city is called a platted community, and that platting began in the 1950s and continued through the 1980s (Port St. Lucie Planning and Zoning FAQ). GDC brought only the land it owned into the city in 1961. The first Comprehensive Plan was approved in 1980; in the early 1980s the state adopted legislation requiring legally binding plans, and the first plan adopted by ordinance followed in 1983. The FAQ adds that a state DCA decision found certain areas platted by GDC grandfathered or vested to single-family use notwithstanding later plan changes.

Yes, Tradition and St. Lucie West are both inside the City of Port St. Lucie, but neither belongs to the original platted city, and St. Lucie West has its own services district.

The planning FAQ lists St. Lucie West, the properties west of I-95 (Tradition, Southern Grove, Western Grove, Riverland and Wilson Groves) and some properties along US 1 as areas that are not considered part of the original platted city (growth and development FAQ).

A city fact sheet describes Southern Grove as a 3,605-acre Development of Regional Impact south of Tradition Parkway, part of an 8,200-acre region known to the public and marketed as Tradition; the Southern Grove section runs south of Tradition Parkway and north of the Martin County line by Becker Road (Southern Grove fact sheet). The same fact sheet describes Western Grove as the undeveloped western region of Tradition, 1,593 acres that can eventually hold 4,000 residential units, and it says the Southern Grove commercial land has long been envisioned as the city's future jobs corridor.

St. Lucie West is served by the St. Lucie West Services District, which its own site describes as a community development district overseeing St. Lucie West; its Florida Administrative Code chapter 42I-1 rules on creation, boundary and supervisors carry an effective date of 1/1/1990 (Florida Administrative Code chapter 42I-1). The district's site covers drinking water, wastewater treatment and reuse, an irrigation water schedule, lake upkeep and stormwater drainage for St. Lucie West (St. Lucie West Services District). The district runs its own billing and customer service for St. Lucie West accounts.

Port St. Lucie has a council-manager government: a five-member elected City Council sets policy and appoints a City Manager to run daily operations and a City Attorney for legal advice.

The Mayor and City Council page explains the structure. Each council member, including the Mayor, has one vote, so legislative authority is spread equally among all five members (Port St. Lucie Mayor and City Council page). Council members must live in the district they represent, but residents throughout Port St. Lucie vote for every council seat, and the Mayor is elected at large and can live anywhere in the city. The Mayor and council members serve 4-year staggered terms.

The council office can be reached at 772-871-5159 (alternate 772-871-1775) at Port St. Lucie City Hall, 121 SW Port St. Lucie Blvd. The council page also links a council district map, the council rules and the city strategic plan. The Port St. Lucie government section covers how the departments are organized, how public records requests and city jobs work, and which office to call first.

Three city items are dated on official pages: a lower property tax rate for FY 2026-27, a $65 million upgrade of the Westport wastewater plant and the 110-acre Tradition Regional Park.

At its annual Summer Workshop held July 22-23, the Port St. Lucie City Council approved a property tax (millage) rate of 4.8750 for FY 2026-27, a decrease from 4.9750 in FY 2025-26, which the city's July 24, 2026 announcement calls the 11th consecutive year of lower millage (City of Port St. Lucie millage announcement). According to the same announcement, the FY 2026-27 budget year began Oct. 1, 2026.

Port St. Lucie Utility Systems lists the Westport Wastewater Treatment Facility Upgrade as a $65 million project with construction running from January 2024 to Summer 2027, funded in part by a federal grant; the page reports it 54% complete and says Westport has the capacity to treat 6 million gallons per day (Westport upgrade project page). The upgrade targets nutrient reduction in treated wastewater.

On the west side, Tradition Regional Park at 13120 SW Tradition Parkway spans 110 acres near the Fern Lake Roundabout, and the city estimates completion by late 2026 or early 2027 (Tradition Regional Park page). Its signature feature is the PSL BMX facility, with baseball, softball, soccer and multipurpose fields, trails and a canoe and kayak launch planned around it. The park line is 772-878-2277.

Hurricane season in Port St. Lucie runs June 1 through November 30, alerts come through St. Lucie County's Alert St. Lucie system, and flood insurance policies in the city carry a Community Rating System discount.

The Port St. Lucie Office of Emergency Management says the hurricane season runs from June 1 through November 30, asks residents to prepare before it begins, and posts storm updates on the city homepage and social media when a storm threatens (Port St. Lucie Hurricanes and Storms page). It points residents to sign up for St. Lucie County emergency notifications at stlucieco.gov/alert and recommends a supply kit with food and water for at least 1 week. The county's portal describes Alert St. Lucie as texts, emails or phone calls about major traffic accidents, weather alerts and other issues from area public safety and law enforcement agencies, and it hosts the shelter list, evacuation notices and a secure registry for family members with special needs (St. Lucie County Emergency Preparedness Portal).

Evacuation orders in Port St. Lucie go by lettered zone. The state evacuation zone program run by the Florida Division of Emergency Management explains that Zone A is typically the most vulnerable and the most likely to evacuate first (state evacuation zone page), and the city page links an interactive zone locator map that shows the evacuation zone for a Port St. Lucie address.

For flood insurance, FEMA's Community Status Book lists the City of Port St. Lucie (community 120287) as participating in the National Flood Insurance Program with a Community Rating System class of 5, worth a 25% discount on policies in the special flood hazard area and 10% outside it, and a currently effective flood map dated 02/19/20 (FEMA NFIP Community Status Book). The Port St. Lucie hurricane preparedness guide and the flood zones and flood insurance guide cover each step in detail.
