Shoreline Stability with Native Habitat Integration

Living seawall and hybrid replacement services for waterfront properties in Merritt Island, Florida.

If your shoreline is eroding and you want to stabilize it without building a solid concrete or vinyl wall, a living seawall combines structural elements with native vegetation to hold soil in place while creating habitat for fish and crabs. You will often see this system installed in environmentally sensitive areas near Merritt Island where regulations limit hard armoring or where homeowners prefer a shoreline that blends with the natural landscape. Precision Docks & Seawalls designs and installs hybrid seawalls that use rock, plants, and sometimes oyster-based systems to absorb wave energy and reduce erosion in Merritt Island.


A living seawall typically includes a structural base such as riprap or a low retaining wall, with pockets or terraces where marsh grasses, mangroves, or other salt-tolerant plants are installed. The roots anchor the soil and slow water flow, while the rock or shell base prevents the shoreline from washing away during storms. We assess your property's slope, tidal range, and soil type before recommending a design, and we work with local environmental agencies to confirm that the materials and plants meet permitting requirements.

How the System Works After Installation

After a living seawall is installed at your Merritt Island property, you will see native plants taking root along the shoreline and rock or shell material forming a stable base at the waterline. The plants grow over the following months, and their root systems weave through the soil to hold it in place. We use species like cordgrass and saltmarsh bulrush that tolerate flooding and saltwater, and we position them in zones based on how often each area gets submerged during tides.


Once the vegetation matures, the shoreline absorbs wave energy instead of deflecting it, which reduces scour and protects adjacent properties. You may notice more small fish and crabs near the waterline because the plants and rocks create shelter and feeding areas. The system improves habitat while stabilizing the shoreline, and it requires less maintenance than a traditional seawall once the plants are established.


We typically use riprap or bagged oyster shells for the structural base, and we grade the slope to prevent washouts during heavy rain. The plants are installed as plugs or sprigs, and we apply erosion control fabric or coir logs to hold soil until the roots spread. This type of seawall is not suited for vertical banks or areas with severe wave action, and it may take one to two growing seasons for the plants to fully stabilize the shoreline.

What to Know Before You Decide

Homeowners considering a living seawall often ask how quickly the plants establish, whether the system can withstand storms, and what permits are required in Merritt Island.

What makes a living seawall different from a traditional one?

A living seawall uses native plants and natural materials to stabilize the shoreline and create habitat, while a traditional seawall relies on concrete, vinyl, or timber to form a solid barrier. The living version absorbs wave energy instead of deflecting it.

How long does it take for the plants to stabilize the shoreline?

Most native grasses and shrubs take six to twelve months to establish strong root systems. During that time, the rock or shell base holds the soil in place, and erosion control fabric prevents washouts.

When is a living seawall the best choice?

It works best in environmentally sensitive areas with low to moderate wave action, gentle slopes, and enough space for planting. If your shoreline is steep or exposed to heavy boat wakes, a hybrid system with more structural support may be needed.

What maintenance does a living seawall require?

You will need to remove invasive plants and debris that accumulate around the vegetation, and you may need to replant areas that wash out during storms. Once the plants are mature, maintenance is minimal compared to repairing cracked concrete or rotted wood.

How do permitting requirements affect the design in Merritt Island?

Local agencies may require specific plant species, setback distances, or inspections before and after installation. We handle the permitting process and confirm that the design meets state and county regulations for shoreline work.
