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 on LID systems including curb inlets or permeable paving.

===Flow control devices===

LID facilities have been demonstrated to function well throughout frozen periods of the year even when all components were fully frozen for some part of the year. However, where the consequences of even temporary ponding would be entirely unacceptable, [[underdrains]] should be placed below the frost line to reduce the threat ice clogging. [[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.
