Blue and Green Infrastructure uses elements from both green and blue stormwater infrastructure. Implemented these elements can vary greatly in appearance, from high-profile features to those that blend in seamlessly with the surroundings. Blue and Green Infrastructure is typically designed and sized to capture the more frequent storm events.
The focus of Blue and Green Infrastructure is stormwater runoff treatment and capture, which makes it different from coastal strategies (for example, living shorelines, dunes, mangrove plantings and oyster or artificial reefs) that target stressors, such as wave energy, sea level rise and storm surges.
