 *'''Winter Maintenance''': Sand should not be spread on permeable pavement as it can quickly lead to clogging. Deicers should only be used in moderation and only when needed because dissolved constituents are not removed by the pavement system. Pilot studies at the University of New Hampshire Stormwater Center have found that permeable pavement requires 75% less salt than conventional pavement over the course of a typical winter season.<ref>University of New Hampshire Stormwater Center (UNHSC). 2007. 2007 Annual Report.

*'''Snow Plowing''': Permeable pavement is plowed for snow removal like any other pavement. When groundwater contamination from chlorides is a concern, plowed snow piles and snow melt should not be directed to permeable paver and porous pavement systems<ref>Smith, D. 2006. Permeable Interlocking Concrete Pavements; Selection, Design,
Construction, Maintenance. 3rd Edition. Interlocking Concrete Pavement Institute.Burlington, ON.</ref><br>Also, plowed snow/snow piles should not be stored on top of permeable pavements, since this snow often contains granular materials which can contribute to clogging
