Line 23:
Line 23: *[[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 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. *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>
