- Estimated sediment accumulation depth (inches)
Infiltration & Media
- Does the BMP drain down within the design time (no prolonged standing water)? *
- Is permeable pavement surface free of clogging (infiltration confirmed)?
- Is the engineered media/mulch layer intact and at proper depth?
- Are underdrains and cleanouts functioning?
Vegetation & Erosion
- Is vegetation healthy with target coverage and free of invasive species? *
- Is the BMP free of erosion, scour, or channelization? *
