Low impact development is an approach to land development (or redevelopment) that incorporates natural features to manage stormwater and protect water quality. Low impact development minimizes runoff by promoting infiltration, evapotranspiration, and collection for use through natural landscape features and fewer impervious surfaces. The result is a functional and visually appealing development that treats stormwater as a resource, not as waste. 

Green streets refer to transportation rights-of-way that use natural features, landscaping, and water quality protection elements to reduce stormwater runoff and improve water quality while creating aesthetically pleasing, livable communities. Common features of green streets include alternative street designs, swales, bioretention curb extensions, sidewalk planters, permeable pavement, and sidewalk trees and vegetation.
