===Excavation and mass grading: final excavated grade and verification===
===Excavation and mass grading: final excavated grade and verification===
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. <br/>

#Excavate from the rough grade to the finish grade using appropriate equipment. This is often done with hand tools.
