This area will now experience increased runoff when rain occurs because the paved parking lot has less permeability.

Explanation:

Soil refers to thin sheet of layer composed of organic and inorganic matters on the surface of the earth. Through soil water can penetrate into the next underlying horizons. Soil horizons are represented by soil profile. Permeability refers to the capacity of passing and holding water of the layer.

When a soil surface get paved through cementation it can not hold water because it lost percolation capacity. For this the surface run off increases which results into flood and depletion of ground water. Less permeability occurs due to the construction of pavements over the soil surface.
