<h3>Physical Suitability and Constraints</h3>
In general, permeable pavement systems can be used almost anywhere a traditionally paved system might have been installed. However, these systems have the same site constraints of any infiltration practice and should meet the following criteria:

*Wellhead Protection: Permeable pavement should not be used for road or parking surfaces within
*Wellhead Protection: Permeable pavement should not be used for road or parking surfaces within two (2) year time-of-travel wellhead protection areas.
*Winter Operations: Sand or other granular materials should not be applied as anti-skid agents during winter operation because they can quickly clog the system. Winter maintenance practices should be limited to plowing, with de-icing salts applied sparingly (i.e., not as a preventative measure).

*Site Topography: The slope of the permeable pavement surface should be at least one percent and no greater than five percent. The impervious land surrounding and draining into the pavement should not exceed 20% slope (Smith, 2006). Pervious surfaces should not drain onto the pavement
