Nature-based Stormwater Strategies are an effective and economical strategy to reduce flooding and improve water quality by mimicking natural water flow to vegetated stormwater infiltration spaces, reducing long-term maintenance costs of conventional stormwater systems.

Inland Highway

An inland highway uses grassed swales to collect and infiltrate runoff, which reduces flooding and discharge to surface waters.

Coastal Roadway

A coastal road uses curb cuts to guide runoff to a roadside infiltration system. Permeable paving on the bike path disconnects runoff and a living shoreline was installed to reduce soundside erosion to protect the roadway.

State DOTs are in the business of maintaining their coastal highways and nature-based solutions should be considered as part of that long-term commitment.
