=== Managing runoff ===

Permeable paving surfaces have been demonstrated as effective in managing [[surface runoff|runoff]] from [[Impervious Surfaces|paved surfaces]] and recharging groundwater aquifers.<ref>Brattebo, B.

Document No. EPA-841-B-00-005B.</ref> Large volumes of [[urban runoff]] causes serious [[erosion]] and [[silt]]ation in [[surface water]] bodies. Permeable pavers provide a solid ground surface, strong enough to take heavy loads, like large vehicles, while at the same time they allow water to filter through the surface and reach the underlying soils, mimicking natural ground absorption.<ref>{{Cite web|url=http://www.chesapeakeecologycenter.org/?page_id=78|title=Permeable Pavers|website=www.chesapeakeecologycenter.org|date=18 May 2016 |language=en-US|access-date=2017-05-15}}</ref> They can reduce downstream flooding and stream bank erosion, and maintain base flows in rivers to keep ecosystems self-sustaining. Permeable pavers also combat erosion that occurs when grass is dry or dead, by replacing grassed areas in suburban and residential environments.<ref>{{Cite news|url=http://www.belgard.com/knowledge_center/planning_materials/permeable_pavers|title=Permeable Pavers|last=Belgard|access-date=2017-05-15|archive-date=2018-01-11|archive-url=https://web.archive.org/web/20180111032530/http://www.belgard.com/knowledge_center/planning_materials/permeable_pavers|url-status=dead}}</ref> The goal is to control stormwater at the source, reduce runoff and improve water quality by filtering pollutants in the subsurface layers.<ref name="Scholz2007" />
