This table shows Cost components for stormwater ponds
(Link to this table)
| Implementation Stage | Primary Cost Components | Basic Cost Estimate | Other Considerations |
|---|---|---|---|
| Site Preparation | Tree & plant protection | Protection Cost ($/acre) x Affected Area (acre) | Removal of existing structures, topsoil removal and stockpiling |
| Topsoil salvage | Salvage cost ($/acre) x Affected Area (acre) | ||
| Clearing & grubbing | Clearing Cost ($/acre) x Affected Area (acre) | ||
| Site Formation | Excavation / grading | 8-ft Depth Excavation Cost ($/acre) x Area (acre) | Soil & rock fill material, tunneling |
| Hauling material offsite | Excavation Cost x (% of Material to be hauled away) | ||
| Structural Components | Inlet structure | ($/structure) | Pipes, catchbasins, manholes, valves |
| Outlet structure | ($/structure) | ||
| Site Restoration | Seeding or sodding | Seeding Cost ($/acre) x Seeded Area (acre) | Tree protection, soil amendments, seed bed preparation, trails |
| Planting / transplanting | Planting Cost ($/acre) x Planted Area (acre) | ||
| Annual Operation, Maintenance, and Inspection | Debris removal | Removal Cost ($/acre) x Area (acre) x Frequency (2 / 1yr) | Vegetation maintenance, cleaning of structures |
| Sediment removal | Removal Cost ($/acre) x Area (acre) x Frequency (1 / 5yr) | ||
| Gate / valve operation | Operation Cost ($) x Operation Frequency (2 / 1 yr) | ||
| Inspection | Inspection Cost ($) x Inspection Frequency (2 / 1 yr) | ||
| Mowing | Mowing Cost ($) x Mowing Frequency (4 / 1 yr) |
