How does sub‑dune drainage reduce storm damage?

By lowering pore pressure and accelerating drawdown after surge events, reducing dune slumping and scour.

What permits are required?

Typically coastal construction line approvals, environmental permits, and local right‑of‑way permissions.

flood storage within the embedded drainage. The modified concrete culverts capture any floodwaters that overtop the glass and concrete flood waters.

Public Access

Integrated Boardwalk

tops the modified concrete culvert and hides it from public view. The added benefit of the boardwalk is it

creates and maintains

public access.

Nature - Based

The combination of

grey and green elements creates a visually pleasing and new dune ecology that is heavily planted for stabilization and provides a home to local flora and fauna.

How It Works

Wave energy dissapates over vegetated dunes
Embedded drainage stops overtopping
Boardwalk rail acts as an additional surge barrier
