*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.
