Rain gardens are shallow, landscaped depressions that capture and retain stormwater runoff from rooftops, driveways, and other impervious surfaces. By using deep-rooted native plants and well-draining soils, they filter out contaminants like oils, metals, and nutrients. They can also reduce the risk of localized flooding by allowing water to infiltrate the ground, and provide essential habitat for pollinators and other wildlife

Bioswales are linear, vegetated channels that manage and treat stormwater runoff by slowing its flow, allowing it to infiltrate the soil, and enhancing groundwater recharge. Often incorporating native plants, mulch, and engineered soils, they effectively capture and filter pollutants while also adding aesthetic and ecological value to urban spaces, making them ideal for managing stormwater along roadways, parking lots, and other paved areas.

Permeable pavers are a type of pavement that allows water to pass through voids between the paving materials, reducing surface runoff and filtering pollutants before they reach waterways. By contributing to stormwater management, mitigating the urban heat island effect, and supporting sustainable and resilient urban development, permeable pavers help reduce flooding while promoting environmental sustainability.

Green roofs, also known as vegetated roofs, are roofing systems covered with layers of vegetation, soil, and waterproof membranes that manage stormwater by capturing and absorbing rainfall, reducing both the volume and rate of runoff. In addition to mitigating the urban heat island effect, they improve building energy efficiency by providing insulation, create habitat for pollinators and other wildlife, and extend the lifespan of roofing materials by protecting them from UV exposure and temperature fluctuations. Green roofs can be extensive (lightweight with shallow soil and low-maintenance plants) or intensive (deeper soil that supports a wider variety of plants, including trees and shrubs), both of which contribute to stormwater management and urban greening efforts.
