Permeable Pavement (with flow barrier) Photo Requirements for Certification:
Flow barrier height must be 12” minimum (per the approved plan).
Each flow barrier must have an impermeable liner installed over stone (if utilized) to prevent water flow from upper to lower cell. If concrete or CMU block flow barrier is installed, no liner is required.
Do not create multiple flow barriers if this creates a shortage of drainage area (i.e., 20’ driveway should only have one flow barrier).
