Permeable pavement is an alternative to traditional asphalt or concrete and provides runoff reduction and water quality improvements provided it is properly maintained. The biggest challenge with this stormwater control measure is that it clogs over time. There is uncertainty around how to plan for maintenance, its associated costs, and what techniques to use to ensure long-term hydraulic function of these systems. This presentation will bring together nearly 10 years of field collected data on permeable pavement maintenance to determine: (1) how the engineering design of permeable pavements affects the rate at which they clog, (2) if a pavement is clogged, (3) maintenance scheduling, and (4) techniques for routine and restorative maintenance.
