Site ID/Name: Location: Inspector: Date: GOOD EXAMPLES PERMEABLE PAVEMENT Permeable Interlocking Concrete Pavement (PICP) GENERAL INSPECTION QUESTIONS Note: ‘Yes’ indicates a maintenance need and action General: 1. Is access to the site inadequately maintained for inspection and maintenance? 2. Is there evidence of runoff short-circuiting (going around) the practice? 3. Is there evidence of gullies, rills, or erosion around the practice? Drainage Area: (pertains to the surrounding landscape that will contribute runoff to the practice) 4. Does the vegetation around the practice need to be pruned/mowed? Is vegetation unhealthy? signs of bare/dead grass) Note: grass clippings should be removed. 5. Is there any exposed or unstable soil around the practice that could cause sediment accumulation within the practice? Permeable Pavement Surface: 6. Is there evidence of long-term ponding or standing water in the practice? QUALITATIVE INSPECTION QUESTIONS (GOOD/MARGINAL/POOR) Note: ‘Poor’ indicates a maintenance need and action 14. Rate the presence of undesirable vegetation. YES / NO YES / NO YES / NO YES / NO YES / NO YES / NO 15. Rate the presence of sediment accumulation in pore spaces/aggregate between pavers. 16. Rate the presence of debris leaves, trash, grass clippings) on the permeable pavement surface. 7. Are there signs of the bricks/pavers settling? 8. Do the bricks/pavers show signs of cracks, splitting or structural damage? 9. Is there aggregate missing between the bricks/pavers? YES / NO YES / NO YES / NO Inlets/Outlets: 10. Do drainage ways (overland flow or pipes) to the practice have trash, debris, large branches, etc. present? 11. If cleanouts are included, are caps missing? 12. If an underdrain system is included, are there signs of it clogging or a blockage? 13. Does the emergency overflow have trash, debris, sediment or structural damage present? YES / NO YES / NO YES / NO YES / NO Special Scenario (Concrete Grid Pavers with Vegetation): A. Is the grass in the concrete grid unhealthy? dead grass or bare spots) B. Is the grass in the concrete grid unmowed or are grass clippings present?
