===Routine Operation Inspections===

===Routine Operation Inspections===

Routine Operation inspections should be the responsibility of the property owner or their contractors. At a minimum, Routine Operation inspections should occur annually, but twice annually (in spring and fall seasons) is preferable for vegetated BMPs. More frequent inspections may be warranted for highly visible BMPs, those receiving drainage from high traffic areas (vehicle or pedestrian), or those designed with larger than recommended impervious drainage area to pervious BMP footprint area ratio (i.e., I:P ratio). Feedback from inspections should be used to immediately address routine maintenance needs, schedule structural repairs or further investigations into potential problems with BMP function and to adjust the preset schedule of routine maintenance tasks to optimize the use of program resources.

===Verification Inspections===

*More frequent Performance Verification inspections may be warranted for BMPs draining to highly sensitive receiving waters or habitat of species at risk. Testing of functional performance (e.g., surface infiltration rate testing, natural or simulated storm event testing, continuous monitoring) is done in addition to Maintenance Verification inspection indicators (i.e., visual indicators and sediment accumulation testing).

Feedback from inspections should be used to schedule repair or rehabilitation tasks, further investigations into observed problems with BMP function (see Forensic Inspection and Testing section below), or initiate compliance enforcement actions if warranted.

==[[Key Design and Plan Review Considerations]]==

Designing LID BMPs with ease of inspection and maintenance in mind is critical to the affordability of municipal stormwater infrastructure asset management programs and must be considered early on in the plan review stage. Learn more about these common considerations including, providing runoff pretreatment, designing low maintenance conveyance systems, inspection & maintenance of associated features, and inclusion of planting and sediment removal plans.
