This road could be considered superior to any Roman road. [10] Roman roads varied from simple corduroy roads to paved roads using deep roadbeds of tamped rubble as an underlying layer to ensure that they kept dry, as the water would flow out from between the stones and fragments of rubble, instead of becoming mud in clay soils.
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.
A road is an identifiable route, way or path between two or more places. [1] Roads are typically smoothed, paved, or otherwise prepared to allow easy travel; [2] though they need not be, and historically many roads were simply recognizable routes without any formal construction or maintenance. [3]
As stormwater is channeled into storm drains and surface waters, the natural sediment load discharged to receiving waters decreases, but the water flow and velocity increases. In fact, the impervious cover in a typical city creates five times the runoff of a typical woodland of the same size.
A new section of road being built near Hindhead, UK, to replace a four-mile section of the A3 road, and which includes the new Hindhead Tunnel, is expected by the government to deliver environmental benefits to the immediate area including the removal of daily congestion, the elimination of air pollution in Hindhead caused by the congestion ...
In some areas, especially along the U.S. coast, polluted runoff from roads and highways may be the largest source of water pollution. For example, about 75 percent of the toxic chemicals getting to Seattle, Washington's Puget Sound are carried by stormwater that runs off paved roads and driveways, rooftops, yards, and other developed land.

There are several dirt roads within the Uncompahgre; some are mining roads left from the 1800s mineral rush, others are occasionally used by the Forest Service. Paved roads include the San Juan Skyway, Alpine Loop, the Unaweep-Tabeguache Scenic and Historic Byway and Owl Creek Pass, which is gravel.
