Roads present many opportunities for green infrastructure application. One principle of green infrastructure involves reducing and treating stormwater close to its source. Urban transportation right-of-ways integrated with green techniques are often called “green streets”. Green streets provide a source control for a main contributor of stormwater runoff and pollutant load. This course presents methods for using green-street designs to alleviate pollution from urban stormwater runoff.

Topics: Importance of street width in controlling stormwater runoff Use of bioretention curb extensions and sidewalk planters Application of permeable pavement forms Use of sidewalk trees and tree boxes Implementation hurdles Case study: Portland Green Street Pilot Projects

Case study: Chicago Green Alley Program Intended Audience: civil and environmental engineers concerned with stormwater runoff and resulting water pollution issues. Publication Source: US Environmental Protection Agency
