>>heat island effects are not caused by yards and vegetation, but by expanses of dark asphalt and dark roofs. More vegetation vs roads/lots, and roof area is the cure, not the cause.

>>Most often is done by limiting street parking, narrower streets, and using the rear-entrance drives and lots as done in many cities.

YES, limiting on-street parking is huge.

If there are trees on both sides of a residential street it will not be a heat island even with on-street parking. But it seems to me many Americans don’t like trees and prefer open spaces (which inevitably work as heat islands).
