[[Underdrain]] perforated pipes should be located below the frost line to reduce the threat of ice clogging. Ontario provincial standard drawings of frost penetration depth are available from the [https://www.library.mto.gov.on.ca/SydneyPLUS/TechPubs/Portal/tp/opsViews.aspx Ministry of Transportation] as OPSD 3090.100 for northern Ontario <ref> Ministry of Transportation. 2010.

[[Weirs]] are generally less prone to clogging from ice than [[orifices]] under all flow conditions, proprietary low flow devices are also available which are designed to mitigate clogging from ice or other solid debris.

Rubber plow blades are increasingly available and required in many jurisdictions. Their use reduces damage to all kinds of pavement surfaces and they are particularly recommended for application where LID facilities exist, such as permeable pavements and curb cut inlets of bioretention, bioswales, swales and stormwater tree trenches.
