Florida Mandates Living Shorelines to Safeguard Treasure Coast

Opinion | TC Sentinel Editorial Board

Set aside, for a moment, everything the Florida Legislature failed to do this session — the affordability crisis left to fester, the sprawl-enabling bills signed into law, the pro-developer measures that keep tying local governments' hands when they try to protect their own communities. Tuck all of that away.

Buried inside a session that environmental advocates will rightly remember as a near-total defeat, one bill passed that deserves our full attention here on the Treasure Coast.

Senate Bill 302, the coastal resiliency measure sponsored by Sen. Ileana Garcia, a Republican from Miami, may quietly prove to be the most consequential environmental legislation this state has produced in years. It requires the Florida Department of Environmental Protection to establish guidelines, monitoring criteria, and permitting frameworks for nature-based coastal restoration — the kind that uses mangroves, seagrass beds, living shorelines, and reef restoration rather than concrete seawalls and expensive pump systems that the sea will eventually swallow anyway.

For residents of Martin, St. Lucie, and Indian River counties, this is not an abstraction. The Indian River Lagoon, which runs along our shoreline for more than 150 miles, has been choking for decades — battered by nutrient pollution, seagrass die-offs, and algal blooms that have killed manatees, fish, and the tourism economy that depends on clean water.

A nature-based restoration project already in development in Titusville — just north of our county line — points directly to what SB 302 makes possible: new seagrass beds and plans to deploy approximately one million clams by drone to filter impurities from the water. That kind of innovative, ecosystem-driven work has been stalled for years in part because the state lacked the regulatory framework to support it. SB 302 builds that framework.

Florida has 1,300 miles of coastline and sits on terrain so flat that storm surge — not wind — is what kills people. Hurricane Ian made that brutally clear in 2022, when more than 150 people died, most from water. Our own St. Lucie County has faced increasing flood risk in recent hurricane seasons. The old answer to that threat — pile up concrete, hand out construction contracts, repeat — has proven both inadequate and ruinously expensive.

Studies cited by the Environmental Defense Fund, which helped shepherd SB 302 through three years of legislative effort, indicate that mangrove planting and living shoreline construction cost significantly less than equivalent hard-infrastructure projects.

Supporters of the status quo will argue that concrete seawalls and engineered structures provide certainty — that you can see them, measure them, and insure them. That is a fair point. Nature-based solutions are not a silver bullet, and no serious advocate for SB 302 claims otherwise. Hybrid approaches, combining natural restoration with selective hard infrastructure where truly necessary, are likely the realistic path forward.

But "coastal resilience" has for too long been Tallahassee's favorite euphemism for doing nothing while issuing contracts. SB 302 gives the term actual regulatory teeth, for the first time obligating the DEP to create the guidance that local governments here have lacked when trying to pursue restoration projects. "People want to see infrastructure that looks like Florida," said Dawn Shirreffs of the Environmental Defense Fund.

The bill's passage was not inevitable. It failed to reach a floor vote as recently as last session and cleared this year's finish line in part because of an unrelated amendment blocking a cruise ship terminal in an aquatic preserve. That is the unglamorous reality of lawmaking.

Now the work falls to implementation — and to us. The DEP must develop its permitting criteria, and that process will involve public comment periods in which Treasure Coast residents, lagoon advocates, commercial fishermen, and local governments should be loud and specific. The Indian River Lagoon Council and the county environmental agencies in Martin, St. Lucie, and Indian River should be at every table.

Our concrete ask: The Martin County Commission, the St. Lucie County Commission, and the Indian River County Commission should each formally direct their environmental staff — before the end of this calendar year — to identify at least one pilot living shoreline or seagrass restoration project eligible for DEP permitting under the SB 302 framework and to report back with a timeline for application. The lagoon does not have the luxury of waiting for Tallahassee to send an invitation.

The Legislature handed us an opening. Rare enough that it deserves acknowledgment. Rarer still that we use it wisely.
