Link to this table

Implementation Stage Primary Cost Components Basic Cost Estimate Other Considerations
Site Preparation Tree & plant protection Protection Cost ($/acre) * Affected Area (acre) Removal of existing structures, topsoil removal and stockpiling
Infiltration area protection Silt fence cost ($/’foot) * Perimeter of infiltration area
Clearing & grubbing Clearing Cost ($/acre) * Affected Area (acre)
Topsoil salvage Salvage Cost ($/acre) * Affected Area
Site Formation Excavation / grading X-ft Depth Excavation Cost ($/acre) * Area (acre) Soil & rock fill material, tunneling
Hauling material offsite Excavation Cost * (% of Material to be hauled away)
Structural Components Vault structure (for underground infiltration) ($/structure) Pipes, catchbasins, manholes, valves, vaults
Media (for infiltration trenches) Media cost ($/cubic yard) * filter volume (cubic yard)
Geotextile Geotextile cost ($/cy) * area of trench, including walls
inlet structure ($/structure)
Overflow structure ($/structure)
Observation well ($/structure)
Site Restoration Soil preparation Topsoil or amendment cost ($/acre) * Area (acre) Tree protection, soil amendments, seed bed preparation, trails
Seeding Seeding Cost ($/acre) * Seeded Area (acre)
Filter strip Sod cost ($/square foot) * filter strip area
Planting / transplanting Planting Cost ($/acre) * Planted Area (acre)
Annual Operation, Maintenance, and Inspection Sediment removal Removal Cost ($/acre) * Area (acre) * Frequency (1 time per 5 years) Vegetation maintenance, cleaning of structures
