==Tips to Preserve Basic BMP Function==
*Never use sealants on porous asphalt nor pervious concrete.
*Prohibit access by [[construction]] vehicles to prevent tracking of [[sediment]] on to the surface.
*Prohibit storage of [[soil]], [[compost]], [[sand]], [[salt]] or unwashed [[gravel]] on permeable pavements to prevent clogging of joints or pores, or protect the pavement surface with tarps or [[geotextile]] during temporary storage of such materials.
*Landscaped areas adjacent to permeable pavements should be covered with [[vegetation]] and not drain to the pavement where possible to prevent eroding soil from reaching the surface.
*Use a mulching mower to mow permeable interlocking grid systems with [[grasses|grass]] cover.
*Permeable pavements can be [[Winter|plowed]] for snow removal like conventional pavements. To reduce the risk of dislodging pavers or grids and minimize displacement of joint/cell fill material, the plow blade should be slightly raised off the pavement surface (e.g., 0.6 cm or 1/4”) with a shoe attachment.
*Plowed snow piles should not be stored on permeable pavements to reduce the risk of [[clogging]] from [[sediment]] accumulation upon melting.
*Do not spread [[sand]] on permeable pavements as part of [[Winter|winter maintenance]] as it will quickly clog the joints or pores and impair drainage function. On permeable interlocking pavers and grid systems filled with gravel, if application of an anti-skid material is desirable, spread the same fine washed gravel material used to fill the paver joints or grid cells; and
*[[Salt|De-icers]] should be used sparingly, as needed during winter. Due to their freely draining design, ice will not form on permeable pavements as readily as it does on conventional impermeable pavements during winter thaw-freeze cycles.
