What is a living shoreline?
A living shoreline holds the bank with plants, shell and rock instead of a vertical wall. NOAA describes it as an option for sheltered coasts, bays and estuaries, not for open-ocean beaches. NOAA living shoreline guidance
Many designs pair a planted marsh edge with a low sill or breakwater just offshore. The sill breaks small waves so the plants can root. Riprap, a sloped layer of rock, is the harder option on the same spectrum.
NOAA advises choosing stabilization site by site, because armoring changes how sand moves and can limit habitat and beach movement. NOAA shoreline guidance For the open Gulf beach, see the Gulf-front armoring guide instead.

| Project | What was built | Funding on record |
|---|---|---|
Naval Support Activity, Upper Grand Lagoon, started 2010 | About 1 acre of oyster reef and 0.5 acre of marsh, with over 15,000 square feet planted NOAA Restoration Atlas | NOAA $25,000, partner $25,000 and other non-federal $58,600, plus volunteers NOAA Restoration Center project 2744 |
St. Andrew Bay shoreline, Panama City Beach, 2003 | A failing bulkhead removed by barge and replaced with smooth cordgrass and black needlerush on 0.2 acre of tidal wetland | NOAA $1,200 and partner $1,200, with 16 volunteers NOAA Restoration Center project 937 |
East Bay Living Shoreline and Seagrass Project | A Bay County project listed as active | $500,000 RESTORE Act award, December 9, 2022 U.S. Treasury RESTORE awards |
EPA's 2013 Gulf Guardian Award release says the Naval Support Activity project covered 2,800 feet of shoreline, using oyster reef and grass plantings instead of riprap or concrete seawalls. EPA Gulf Guardian release, 2013
Volunteer labor means these figures are not contractor prices. They do show the methods have been built on local bay shores.
Will it work on my shoreline?
NOAA's site checklist looks at wave energy, tidal range, slope, elevation, soil, vegetation, neighboring shores and drainage. NOAA site considerations Wind direction and the bank's erosion history matter too. NOAA site assessment
The St. Andrew Bay water management plan calls living shorelines "particularly applicable" to altered and hardened estuarine shorelines. It notes some urban bayous offer relatively low-energy sites. NWFWMD St. Andrew Bay SWIM plan
| Shoreline | Likely fit |
|---|---|
Sheltered bayou or cove with a gentle slope | A good candidate for marsh with a low sill |
Open bay with a long fetch | Possible with a stronger sill or rock, after design |
Narrow canal with docks on both sides | Little room; a riprap toe or habitat features on the wall may fit better |
Open Gulf beach | Not a living shoreline site; dunes and beach fill do this job |
Fetch is the stretch of open water the wind blows across toward your shore. Tides here are small, about 1.3 feet from low to high at Panama City, so marsh plants have a narrow band to grow in. NOAA datums, Panama City
Local rules lean toward softer edges
- In aquatic preserves, converting a vertical bulkhead to riprap or vegetation is a listed public-interest benefit. Rule 18-20.004(2)(d)4.
- No new seawall may be built out past the mean high water line inside a preserve. Rule 18-20.004(1)(c)
- Gulf County prohibits new vertical seawalls in coastal areas and encourages native vegetation and riprap. Gulf County Coastal Policy 1.4.5
- Bay County's land rules say shorelines "shall remain completely natural," with exceptions where seawalls exist or erosion control is needed. Bay County LDR 2807
DEP's St. Joseph Bay plan says bulkheads can be poor at absorbing wave energy, scouring the bottom and speeding erosion next door. It describes a U.S. Fish and Wildlife Service effort in which homeowners pay for native cordgrass and help plant it, often behind a breakwater of bagged oyster shell or limestone. DEP St. Joseph Bay plan
Ask whether that program is still running before you plan around it. See Port St. Joe and St. Joseph Bay.
Permits for a living shoreline
| Authorization | Key limits |
|---|---|
State ERP exemption for shoreline plantings | 500 feet or less of shoreline, with plants no more than 10 feet out past the mean high water line. An optional breakwater must keep its top at or below mean high water, stay 3 feet from seagrass and leave a 5-foot gap every 75 feet Rule 62-330.051(12)(e) |
Federal Nationwide Permit 54 | Sheltered water with low to moderate waves, built mostly of plants or reef. No more than 30 feet out past mean low water, or 500 feet along the bank, unless waived 2026 NWP 54 |
State submerged land consent | Riprap, groins or breakwaters up to 10 feet out past the mean high water line Rule 18-21.005 |
Proposed DEP general permit | Noticed October 20, 2025 but not adopted as of October 27, 2026, so do not plan around it Proposed Rule 62-330.604 |
The plantings exemption also calls for commercially grown native stock and removal of invasive plants. Rule 62-330.051(12)(e) A living shoreline still needs every applicable local, state and federal approval before work starts. NOAA permitting note

Seagrass sets the footprint
In 2010 mapping, about 12,200 acres of seagrass grew in the St. Andrew Bay system and about 7,200 acres in St. Joseph Bay. Prop scarring was increasing in southern St. Joseph Bay. NWFWMD St. Andrew Bay SWIM plan
DEP's St. Joseph Bay plan warns that dock pilings displace grass, decking shades it and seagrass recovers slowly. DEP St. Joseph Bay plan A sill or breakwater placed on grass trades one habitat for another.
- Ask for a seagrass survey before design.
- Keep sills, rock and work barges off grass beds.
- Route the dock walkway around the grass, not through it.
Keep the wall, add habitat
A full living shoreline is not the only option. The 2026 Nationwide Permit 13 expressly allows nature-based features next to a seawall, such as textured faces, rock clusters or shellfish bags. 2026 NWP 13
A rock toe in front of an existing wall can reduce scour and add habitat at the same time. See riprap and toe protection.
The St. Andrew and St. Joseph Bays Estuary Program at FSU Panama City adopted its first management plan in 2024 and reports 54 vertical oyster gardens deployed. FSU Panama City release Estuary Program 2025 report It is a useful local contact for habitat ideas.
Cost and care over time
No public record found here shows what a homeowner paid a contractor for a living shoreline. The local projects above relied on grants and volunteers. Compare written quotes using the cost guide.
NOAA treats monitoring and maintenance as part of the project. NOAA site considerations
- Who replants if plants fail in the first season?
- Who resets sill material after a storm?
- What does success look like at one year and at three years?
Bay County shores where planted designs fit
These guides cover calm Bay County water where marsh, reef or a low sill is worth pricing next to a wall.
- Grand Lagoon, Thomas Drive & Bay Point: a 2010 project in Upper Grand Lagoon built about 1 acre of oyster reef and half an acre of marsh. NOAA Restoration Atlas
- West Bay & Breakfast Point: the bay is edged by salt marsh, oyster bars and seagrass, and state rules exempt native plantings along 500 feet or less. Rule 62-330.051(12)(e)
- Sandy Creek, Allanton & East Bay: Tyndall began a hybrid oyster reef at Baker's Point in October 2024. Tyndall AFB
- Indian Pass & Indian Lagoon: a quiet shellfish lagoon where low-energy, planted options suit the water. Shellfish area
