Excavation and mass grading: final excavated grade and verification[edit]

LID designs typically have very specific grading requirements. Verifying depths and slopes is critical for optimal performance of the facility. For example, if the design calls for a channel with a 1 % slope, the channel may not function as designed if it has a 2 % slope instead. Similarly, if the designs call for 1 metre of excavation from grade and only 90 cm are excavated, it will not have enough storage space to meet the design criteria.
Construction steps

  1. Excavate from the rough grade to the finish grade using appropriate equipment. This is often done with hand tools.
  2. Confirm excavation depths and slopes using appropriate equipment (transit levels, global navigation satellite systems, etc.)

Key inspection points

  • Confirm final excavated depths and slopes.

Mistakes to avoid

  • “Eye-balling” depths and slopes
