| Replace pea gravel/topsoil and top surface filter fabric (when clogged). | As needed |
|
Ensure that contributing area, practice and inlets are clear of debris. Ensure that the contributing area is stabilized. Remove sediment and oil/grease from pre-treatment devices, as well as overflow structures. Mow grass filter strips should be mowed as necessary. Remove grass clippings. Repair undercut and eroded areas at inflow and outflow structures |
Monthly |
| Inspect pre-treatment devices and diversion structures for sediment build-up and structural damage. Remove trees that start to grow in the vicinity of the trench. | Semi-annual Inspection |
| Disc or otherwise aerate basin bottom. De-thatch basin bottom. | Annually |
| Scrape basin bottom and remove sediment. Restore original crosssection and infiltration rate. Seed or sod to restore ground cover. | Every 5 years |
