If a single family residence is constructed on the cleared lot what processes will control the surface runoff from the lot

As the region is deforested, the topography, gravity, soil permeability and terrain slope will control the runoff, as well as the intensity of the rain.

Explanation:

Runoff occurs when water flows over a soil that is saturated, that is, soaked. What controls the runoff efficiently is the native vegetation of the place, however, when this area is cleared, the soil is completely at the mercy of saturation, causing the runoff to be controlled by topography, gravity, permeability of the soil and the slope of the terrain, as well as the intensity of the rain.
