Pretreatment vegetated filter strip (VFS)	Construction sequence	Quarterly and after every 1 in storm event for first two years, then biannually [1]			Sediment removed at least biannually of when buildup exceeds 2 inches in depth	Appropriate vegetation and landscaping maintenance; See Appendix [2]	Generally $100-$1400 per acre
Level-Spreader - Vegetative Filter Strip System (LS-VFS)	Construction notes	Quarterly and after every 1 in storm event for first two years, then biannually [3]			Sediment removed at least biannually of when buildup exceeds 2 inches in depth [4]	Appropriate vegetation and landscaping maintenance; See Appendix [5]	Generally $100-$1400 per acre [6]
Up-Flo Filter		Every 6 months for first year of operation, then site specific.

Storm Clean	One-person installation	Monthly	Maintenance instructions		When visual inspection or water sampling show degradation. MetalZorb is non-hazardous and does not require special waste handling		Vactor truck or large shop vac; One person [8]
Gravel filtration		After each rainfall			Remove sediment from behind bag as needed
Filtration berm	Construction sequence	After each rainfall [9]	Maintenance considerations		Routinely remove accumulated trash and debris [10]	Appropriate vegetation and landscaping maintenance (eg. mowing and level gradient restoration); See Appendix [11]	Depends on height, length, width, and location of berm [12]
SiltSoxx R by Filtrexx	Installation instructions	Within 24 hours after rainfall event [13]	Maintenance instructions		Sediment removal from upslope side when accumulation has reached ½ the effective height of the Soxx [14]
StormExx	Installation notes	Every 90 days, frequent drive through inspection during leaf-fall and after storm events [15]		Costs for one year of service and maintenance may be added to proposal [16]	Quarterly general service, fall cleaning and cartridge replacement [17]
