Port St. Lucie FL Water Restrictions 2026

Current water restrictions in Port St. Lucie, Florida

Port St. Lucie operates under the South Florida Water Management District (SFWMD) year-round mandatory schedule: 2 days per week by address parity, with watering allowed only between 12 a.m.–10 a.m. or 4 p.m.–11:59 p.m. The schedule is permanent across SFWMD's service area regardless of drought conditions; it is the baseline rule for outdoor irrigation in South Florida and is not lifted in wet years.

Port St. Lucie is the 8th largest city in Florida — bigger than St. Petersburg, larger than every Tampa Bay city except Tampa itself. The city's population has grown dramatically over the past 20 years, driven by master-planned community development west of I-95 and the conversion of former agricultural land into single-family subdivisions. Population is approximately 231,000 and continues to rise. The city is on the Treasure Coast — the stretch of Atlantic coast between Cape Canaveral and West Palm Beach — and is served by Port St. Lucie Utility Systems (PSLUS).

What makes Port St. Lucie unusually relevant to Florida's water-quality and drought conversations is the Indian River Lagoon, which forms the city's eastern boundary. The lagoon — one of the most biodiverse estuaries in the Northern Hemisphere — has been suffering for years from harmful algal blooms driven by excess nutrient runoff: nitrogen and phosphorus from residential lawns, agricultural fields, and aging septic systems. Excessive irrigation contributes to runoff that ultimately reaches the lagoon. Following the schedule is therefore a water-quality intervention as much as it is a water-supply intervention. SFWMD coordinates with the Indian River Lagoon Council on water management decisions.

The other defining infrastructure: the C-23, C-24, and C-25 canals — engineered drainage canals that historically managed water flow across the St. Lucie watershed and feed the lagoon. SFWMD has indicated it will stop withdrawals from C-23, C-24, and C-25 canals if levels drop to 14 feet above sea level, a threshold that triggers additional regional water management actions. The District monitors canal levels weekly.

Watering schedule and allowed hours

Hand watering with a hose fitted with a shut-off nozzle is permitted on any day, outside the daytime blackout. Drip and microirrigation for non-turf plantings are exempt from the day-of-week limit.

• New sod and seed: 30-day establishment variance available through PSLUS.
• Reclaimed water: commercial customers operate on the standard SFWMD year-round schedule.
• Aesthetic water features: must recirculate or be drained.

What happens if you violate restrictions in Port St. Lucie?

PSLUS enforces the SFWMD schedule through Code Enforcement and the utility:

• First violation: a written warning.
• Second and subsequent violations: civil fines per city code.
• Persistent violators: escalating fines and potential service-restriction action.

To report a violation, call PSLUS at 772-871-5131 or use the city's online reporting form.

Other outdoor water rules

• Watering during measurable rain: prohibited. Functioning rain sensors are required on automatic irrigation systems under Florida Statute § 373.62.
• Excessive runoff: water sheeting onto streets, sidewalks, or storm drains is a violation regardless of day or hour. Particularly important given the Indian River Lagoon water-quality context.
• Pressure washing: permitted only for paint, sealant, repair, or required for health and safety.
• Vehicle washing: permitted with a hand-held hose with shut-off nozzle.

Water source and infrastructure

PSLUS draws drinking water from the Floridan Aquifer through municipal wells. The Floridan beneath St. Lucie County is productive but is the same regional system supporting Treasure Coast and broader South Florida demand. Long-term aquifer health depends on managing pumping rates against rainfall recharge, which during drought years runs below average.

The C-23, C-24, and C-25 canals are the surface-water dimension of the city's water landscape:

• C-23 drains southwestern St. Lucie County and discharges into the North Fork of the St. Lucie River.
• C-24 drains central St. Lucie County, also flowing into the North Fork.
• C-25 drains southern St. Lucie and northern Martin counties.

These canals were originally built for agricultural drainage but now serve multiple purposes including stormwater management, water supply for agricultural and some industrial users, and regulated discharge to the Indian River Lagoon. SFWMD's 14-foot minimum level threshold reflects ecological and water-supply concerns: below that level, additional restrictions kick in to protect remaining flow and limit additional environmental damage to the lagoon.

Port St. Lucie also operates a reclaimed-water system that distributes treated wastewater for parks, golf courses, and select commercial properties. The system reduces potable demand and reduces nutrient discharge to the lagoon — both important contributions in a city this exposed to lagoon water-quality issues.

HOA, brown lawns, and the Indian River Lagoon

Florida Statute § 720.3075 prohibits HOAs from enforcing covenants requiring irrigation inconsistent with declared water-shortage measures. The statute applies in Port St. Lucie's many HOA-governed master-planned subdivisions. The SFWMD year-round schedule isn't a "declared shortage" in the temporary sense — it's permanent — but the statute also covers the year-round measures the District imposes.

For Port St. Lucie homeowners, there's an additional argument for moderate-water landscaping beyond compliance with the schedule: nutrient runoff to the Indian River Lagoon. Heavily fertilized, heavily irrigated lawns shed more nitrogen and phosphorus to the lagoon than drought-tolerant native plantings. The water-quality benefit of converting some turf to Florida-Friendly landscaping compounds the water-supply benefit.

Sample HOA response:

"Dear [HOA Board], the City of Port St. Lucie operates under the South Florida Water Management District year-round schedule limiting outdoor irrigation to 2 days per week. My lawn reflects compliance with that schedule. Under Florida Statute § 720.3075, the Association may not enforce a covenant inconsistent with the District's water-conservation measures. Please withdraw the violation. Sincerely, [Your name]"

Lawn care for the Treasure Coast

Port St. Lucie lies in USDA Hardiness Zone 10a. Common turf options:

Mow on the high end. St. Augustine retains moisture better at 3.5–4 inches.

Skip summer fertilizer. St. Lucie County's urban-fertilizer ordinance restricts nitrogen and phosphorus during the rainy season — both for water-supply reasons and to protect the Indian River Lagoon from nutrient runoff.

Consider Florida-Friendly conversions. Native plantings, mulched beds, and reduced turf area protect both water supply and lagoon water quality.

Common questions about Port St. Lucie water restrictions

What happens if the C-23 canal drops to 14 feet?

SFWMD will stop withdrawals from C-23, C-24, and C-25 canals if any drops to 14 feet above sea level. The threshold protects remaining canal flow and limits additional ecological damage to the Indian River Lagoon. SFWMD monitors levels weekly and would communicate any cessation publicly. Stopping canal withdrawals could trigger additional restrictions across the St. Lucie watershed.

What days can I water in Port St. Lucie?

Two days per week, by address. Odd addresses water Wednesday and Saturday. Even addresses water Thursday and Sunday. Watering allowed only 12 a.m.–10 a.m. or 4 p.m.–11:59 p.m.

How does my lawn affect the Indian River Lagoon?

Excessive irrigation runoff carries nitrogen and phosphorus from lawn fertilizer into the storm drain system, which ultimately discharges to the lagoon. Excess nutrients drive harmful algal blooms — the same blooms that have damaged seagrass beds, fisheries, and manatee populations in the lagoon. Following the watering schedule, skipping fertilizer during the rainy season, and converting turf to native plantings all reduce nutrient runoff.

Why is the schedule year-round even when it's wet?

The SFWMD year-round schedule is the baseline rule for South Florida — not a temporary drought response. It applies even in wet years because the District has determined that 2 days per week is sufficient for healthy lawns and that permanently capping irrigation produces measurable conservation benefits.

Can the city declare additional restrictions on top of the year-round schedule?

Yes. If SFWMD escalates to a Water Shortage Warning or Water Shortage Order, additional restrictions could layer on top of the year-round schedule. As of 2026, no additional declaration is in place for St. Lucie County, though the District monitors conditions continuously.

Is reclaimed water exempt?

No. SFWMD restrictions apply to all water sources used for landscape irrigation, including reclaimed water.

How long will the year-round schedule last?

It is permanent. The schedule is the baseline rule for SFWMD's service area and is not lifted in wet years.

What time can I water in Port St. Lucie?

Watering is allowed 12am-10am or 4pm-11:59pm. Watering outside these hours is a violation even on your assigned day.

What are the fines for watering violations in Port St. Lucie?

First offense: Warning first offense. Repeat violations: Fines per city code. Contact SFWMD / Port St. Lucie Utility Systems for the full enforcement schedule.
