| Construction Sequence | Satisfactory / Unsatisfactory | Comments |
|---|---|---|
| 1. Pre-Construction | ||
| Pre-construction meeting | ||
| Runoff diverted (Note type of bypass) | ||
| Facility area cleared | ||
| Soil tested for permeability | ||
| Soil tested for phosphorus content (include test method) | ||
| Verify site was not overdug | ||
| Project benchmark near site | ||
| Facility location staked out | ||
| Temporary erosion and sediment protection properly installed | ||
| 2. Excavation | ||
| Lateral slopes completely level | ||
| Soils not compacted during excavation | ||
| Longitudinal slopes within design range | ||
| Stockpile location not adjacent to excavation area and stabilized with vegetation and/ or silt fence | ||
| Verify stockpile is not causing compaction and that it is not eroding | ||
| Was underlying soil ripped or loosened | ||
| Size, location, and inverts per plans | ||
| Side slopes stable | ||
| Groundwater / bedrock verified | ||
| 3. Check dams | ||
| Dimensions per plans | ||
| Spacing and grade installed per plans | ||
| Materials per specifications | ||
| 4. Structural Components | ||
| Outlets installed pre plans | ||
| Underdrain installed to grade | ||
| Pretreatment devices installed per plans | ||
| Soil bed composition and texture conforms to specifications | ||
| Inlets installed per plans | ||
| Underdrain installed per plans | ||
| 5. Vegetation | ||
| For native stormwater step pools, plants and materials ordered 6 months prior to construction | ||
| For native stormwater step pools, construction planned to allow for adequate planting and establishment of plant community | ||
| Complies with planting specs | ||
| Topsoil complies with specs in composition and placement | ||
| Soil properly stabilized for permanent erosion control | ||
| 6. Final Inspection | ||
| Dimensions per plans | ||
| Pretreatment operational | ||
| Inlet/outlet operational | ||
| Check dams operational | ||
| Soil/filter bed permeability verified | ||
| Effective stand of vegetation stabilized | ||
| Construction generated sediments removed | ||
| Contributing watershed stabilized before flow is diverted to the practice | ||
