Cool pavement refers to road, sidewalk, parking, and plaza surfaces designed to stay cooler than conventional dark pavement. Strategies include higher solar reflectance, permeable or evaporative surfaces, shade, material selection, and designs that reduce heat storage.
Urban forests are the trees and wooded green spaces in and around cities. They include street trees, parks, yards, campuses, river corridors, and remnant woodlands, and they can cool neighborhoods, manage stormwater, support wildlife, improve public spaces, and reduce some environmental stresses.
Rain gardens are shallow planted areas that collect runoff from roofs, streets, driveways, and other hard surfaces. They slow water down, let some of it soak into the ground, and use soil and plants to filter pollutants before the water reaches drains, streams, or lakes.
Walkability describes how easy, safe, useful, and pleasant it is for people to reach daily needs on foot or with mobility aids.
Permeable pavement lets rain and snowmelt pass through a hard surface into stone, soil, or an underdrain below. It can reduce runoff, store stormwater near where it falls, and filter some pollutants when it is designed, installed, and maintained well.
