Roads and buildings are typically the main impermeable surfaces. Sidewalks can be made of more permeable materials because they don’t need to handle nearly as much weight, tram lines only really need the rails, everything else can be permeable.
Buildings can be built to either collect their rainwater for later use, or funnel their rain water directly to sewers, reservoirs, or directly into the ground. Buildings also tend to be more beneficial to society per square foot of land than roads are.
Cars being the problem and urban design being the problem is practically the same thing, we’ve deaigned a significantl amount of our urban spaces specifically for cars.

Roads and parking lots are typically the main impermeable surfaces.
I’m including parking garages as parking lots.
