− | Stormwater planters requires regular, routine inspection and maintenance of the landscaping as well as periodic inspection of other parts of the facility, especially in heavily urbanized environments. Routine maintenance should include weeding, pruning, and mulching, similar to other landscaped areas, as well as the removal of trash, debris and sediment accumulated in pretreatment areas, inlets and outlets. Watering may be needed until plant establishment (first 2 years). <br> | + | Stormwater planters requires regular, routine inspection and maintenance of the landscaping as well as periodic inspection of other parts of the facility, especially in heavily urbanized environments.

| Inspections should occur twice annually (spring and late fall) and after major storm events. Inspect for vegetation density (≥ 80% coverage), damage by foot or vehicle traffic, erosion, debris, soil compaction and sediment accumulation, along with any damage to pretreatment devices.<br> | | Inspections should occur twice annually (spring and late fall) and after major storm events.

| Cleanouts and access points should be provided to allow access to the underdrain and overflow pipe. Camera inspection of these pipes should be conducted every 5 years to ensure pipes are free of roots, sediment and debris. Hydraulic flushing or root removal may be needed to clear debris or obstructions. | | Cleanouts and access points should be provided to allow access to the underdrain and overflow pipe.
