Line 1: − {{TOClimit|2}}+ − ==Overview== − {{textbox|Permeable paving is ideal for: − *Projects which accommodate light vehicular traffic or pedestrian traffic, − *Sites which cannot accommodate additional surface area for bioretention}} − − '''The fundamental components of a permeable paving system are:''' − *interlocking blocks with infiltration spaces between, '''or''' − *a poured in place surface without fines, so that the finish is pervious to water − *a bedding course to stabilize the surface − *underground storage layer of aggregate. − − '''Additional components may include:''' − *an underdrain system − − ==Planning considerations== − − <h3>Landscaping</h3> − Landscaped areas must drain away from permeable pavement to prevent sediments from running onto the surface. Urban [[trees]] will benefit from being surrounded by permeable pavement rather than impervious cover, because their roots receive more air and water. Interlocking pavers used around the base of a tree may be removed as the tree grows. − − ==Design== − <h3>Sizing in TTT</h3> − {{:Permeable paving: TTT}} − − <h3>Materials</h3> − <h4>Stone Reservoir</h4> − The stone reservoir must meet both runoff storage and structural support requirements. − The bottom of the reservoir should be level so that water infiltrates evenly. If the system is not designed for infiltration, the bottom should slope at 1 - 5% toward the underdrain. − − A hybrid permeable pavement/soakaway design can feature connection of a roof downspout directly to the stone reservoir of the permeable pavement system, which is sized to store runoff from both the pavement surface and the roof drainage area. − − <h4>Geotextile</h4> − {{:Geotextiles}} − − ==Proprietary Links== − {{:Disclaimer}} − <h3>Pre-cast</h3> − *[https://unilock.com/products/driveways/eco-optiloc/?region=1 Eco-Optioc, Unilock] − *[https://oakspavers.com/products/enviro-pavers Enviro Pavers, Oaks] − *[http://nilex.com/products/pavedrain Pavedrain, distributed by Nilex] − *[http://santerrastonecraft.com/landscape/paving-stones/terra-flo Terra flo, Santerra] − *[http://www.storm-crete.com/ Stormcrete] − <h3>Poured in place</h3>
