Parking lots are highly impervious.. Impervious surfaces are mainly artificial structures—such as pavements (roads, sidewalks, driveways and parking lots, as well as industrial areas such as airports, ports and logistics and distribution centres, all of which use considerable paved areas) that are covered by water-resistant materials such as asphalt, concrete, brick, stone—and rooftops.
Flooded streets in New Orleans Relationship between impervious surfaces and surface runoff Urban runoff is a major cause of urban flooding , the inundation of land or property in a built-up environment caused by rainfall overwhelming the capacity of drainage systems , such as storm sewers . [ 12 ]
In addition to reducing surface runoff, permeable paving systems can trap suspended solids, thereby filtering pollutants from stormwater. [ 2 ] Permeable pavement is commonly used on roads, paths and parking lots subject to light vehicular traffic, such as cycle-paths , service or emergency access lanes, road and airport shoulders, and ...
The largest feature of the parking lot is its paved area, hence, by changing this surface to be more permeable to water the parking lot will drain better. Some surface options are open joint pavers, porous asphalt, pervious concrete, or a turf grid. Drainage may be an important part of a green parking lot because runoff is often a serious concern.
The street has 11% less impervious surface than a regular street. There are 100 evergreen trees and 1100 shrubs along this 3-block stretch of road, and a 2-year study found that the amount of stormwater which leaves the street has been reduced by 99%.

Tens of thousands of California residents will decide whether to permanently relocate or rebuild their homes after the most destructive fires in Los Angeles’ history.
Rain Gardens are shallow depressions filled with an engineered soil mix that supports vegetative growth. They are usually used on individual home lots to capture roof runoff. Typical soil depths range from 6 to 18 inches. The capture ratio is the ratio of the rain garden's area to the impervious area that drains onto it.
