Key components of LID BMPs that should be the subject of sediment accumulation testing (i.e., depth measurements) are described in the table below along with recommended test methods. Depth measurements should be recorded on inspection field data forms provided on each associated [[Inspection and maintenance#Practice-specific Inspection and Maintenance|BMP's I&M page on the wiki]], used to determine if sediment removal maintenance is needed.
