Reduce impervious surfaces
Reducing the amount of paved impervious surface area will provide cooling by lowering the amount of stored heat in surfaces.
Relax requirements for parking to decrease the size of parking lots and spaces, as well as increase the vegetation in highly paved areas.
Considerations for Use
This strategy is best deployed as a component of a larger land use strategy which will vary greatly across municipalities or during development reviews.
