Undisturbed lands have a micro-topography of dips, hummocks and mounds which slow and retain runoff. Site grading smooths out these topographic features. Micro-topography can be restored in areas of ornamental landscaping or naturalization. Any depressed areas should drain within 48 hours, or they may provide breeding habitat for mosquitoes.
