Revision as of 16:23, 14 December 2022
, 2 years ago→STEP recommendations:
*[[Bedding layer]] and [[Permeable pavements: Specifications|joint filler]] should consist of [[clear stone]] and [[gravel]] rather than [[sand]] to prevent [[clogging]].
*[[Bedding layer]] and [[Permeable pavements: Specifications|joint filler]] should consist of [[clear stone]] and [[gravel]] rather than [[sand]] to prevent [[clogging]].
*Granular materials should not be applied as anti-skid agents during [[winter]] because they can quickly clog the system.

*[[Winter Management|Winter maintenance]] practices should be limited to plowing, with [[Salt|de-icing salts]] applied sparingly.

*The [[Permeable pavements: Specifications|slope]] of the permeable pavement surface should be at least 1% and no greater than 5%.
*The [[Permeable pavements: Specifications|slope]] of the permeable pavement surface should be at least 1% and no greater than 5%.
*The impervious land surrounding and draining onto the pavement should not exceed the area of the permeable pavement (1:1 / I:P ratio).

*Pervious surfaces should not drain onto the pavement.
*Pervious surfaces should not drain onto the pavement.
*The [[Permeable pavements: Specifications|storage layer]] must be [[Permeable pavements: Sizing|sized to accommodate runoff]] from the pavement and any impermeable areas draining to it.<br>
