St. Lucie County and the 2030 septic rule
Only northeast St. Lucie County is inside Florida's 2030 Indian River Lagoon septic area: the north edge of Fort Pierce, unincorporated land north of it, St. Lucie Village and North Hutchinson Island. Port St. Lucie is outside it, so the 2030 rule does not apply there, though city sewer rules and other state septic rules still can.

Which parts are inside
The northeast corner, in the Central IRL plan area: north Fort Pierce, St. Lucie Village and North Hutchinson Island. The Central IRL area stops at about latitude 27.46, north of Port St. Lucie, so Port St. Lucie and most of Fort Pierce are outside. Our count is 5,460 septic parcels inside the area: about 4,880 in unincorporated north St. Lucie County, 289 in St. Lucie Village and only about 270 of the roughly 2,460 septic parcels inside Fort Pierce city limits (data). See the Fort Pierce guide. Check your address to be sure.

Is Port St. Lucie included?
No. The program-area line runs north of Port St. Lucie, and our count finds none of the city's roughly 17,600 septic parcels inside it. The 2030 lagoon rule does not apply there. Port St. Lucie Utility Systems still runs a voluntary septic-to-sewer program ($8,258 as of October 1, 2025, payable at $67.90 a month at 0% over 10 years), and other state septic rules apply as they do anywhere in Florida.
Sewer projects
- Fort Pierce Utilities Authority (FPUA): about 3,000 households in FPUA's territory still use septic. In February 2026 FPUA was tentatively awarded more than $200,000 by the Indian River Lagoon Council for septic-to-sewer conversions.
- North Hutchinson Island: a county project to remove about 530 septic tanks, about 340 of them on the lagoon. Owners may pay through an assessment, reported at $535 to $817 a year for 20 years.

Money
We found no open homeowner grant for ENR upgrades in St. Lucie County. Help mostly comes as utility projects and assessments paid over time. If sewer is not coming to your street, the 2030 path is an ENR upgrade at your own cost. FPUA lists its connection at $10,395 with financing, and lower-income owners can try SHIP repair money: see St. Lucie septic and sewer help.
