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. Structural Components | ||
Stone diaphragm installed per plans | ||
Outlets installed pre plans | ||
Check dams installed per 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 | ||
4. Vegetation | ||
For native dry swales, plants and materials ordered 6 months prior to construction | ||
For native dry swales, 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 | ||
5. Final Inspection | ||
Dimensions per plans | ||
Pre-treatment operational | ||
Check dams operational | ||
Inlet/outlet/underdrain operational | ||
Soil/media/filter bed permeability verified | ||
Effective stand of vegetation stabilized | ||
Construction generated sediments removed | ||
Contributing watershed stabilized before flow is diverted to the practice | ||
