How does the replacing grass with cement and asphalt impact flooding after a heavy rain?
It promotes extra growth of vegetation, which prevents flooding. It doesn't require watering or mowing and helps prevent flooding. It allows rainwater to seep into the ground, which prevents flooding. It prevents rainwater from seeping into the ground, causing water to stay on the surface.
Replacing grass with cement and asphalt prevents rainwater from seeping into the ground, causing water to stay on the surface. This can lead to increased surface runoff and a higher risk of flooding during heavy rain events, as the impermeable surfaces do not absorb water like natural vegetation does.
