The Coastal Toolbox
There is no single fix for coastal erosion. The right solution depends on the local sand system, wave climate, infrastructure, ecology, funding, and community goals.
Restore Sand Supply
Some beaches are shrinking because less sand reaches the coast than before. Restoring sediment flows can include river and creek management, dam sediment strategies, bluff sediment considerations, and regional sediment planning.
Add Sand Where Needed
Beach nourishment places compatible sand back into the system. Done well, it can rebuild beach width, restore recreation, protect infrastructure, and buy time for longer-term management.
Keep Sand in the System
Sand retention tools — including reefs, groins, speed bumps, dunes, and bypass systems — can help manage how sand moves, but they must be designed for local conditions.
Monitor and Adapt
Beaches change with varying wave energy and during storms. Good coastal management requires surveys, data, maintenance, and the willingness to adapt.
Be Careful With Hard Armor
Seawalls, revetments, and rock can protect infrastructure in emergencies, but they can also narrow beaches over time if used without a sand plan.
The Difference Is Management
The same tool can help in one place and fail in another. BBOB does not advocate for a single universal solution. We advocate for understanding the local system, choosing tools carefully, monitoring results, and funding beaches like the public infrastructure they are.
