Maintenance of permeable pavement includes a review of its condition and performance. A spring maintenance inspection is recommended and cleanup conducted as needed. The following are recommended annual maintenance inspection points for permeable pavements:

  • The drawdown rate should be measured at the observation well for three (3) days following a storm event in excess of 1/2 inch in depth. If standing water is still observed in the well after three days, this is a clear sign that subgrade soil clogging is a problem.
  • Inspect the surface for evidence of sediment deposition, organic debris, staining or ponding that may indicate surface clogging. If any signs of clogging are noted, schedule a vacuum sweeper to remove deposited material. Then test sections using ASTM C1701 to ensure that the surface attains an infiltration rate of at least 10 inches/hr.
  • Inspect the structural integrity of the pavement surface, looking for signs of surface deterioration, such as slumping, cracking, spalling or broken pavers. Replace or repair affected areas as necessary.
  • Check inlets, pretreatment cells and any flow diversion structures for sediment buildup and structural damage. Remove the sediment.
  • Inspect the condition of the observation well and make sure it is capped.

Inspect any contributing drainage area for any controllable sources of sediment or erosion.
