STEP divides the construction process for LID practices into five categories:  

STEP divides the construction process for LID practices into five over-arching stages:

#Pre-construction

#Pre-construction

#Excavation and grading

#Excavation and grading

#Backfill granular, utilities and pipes

#Backfill granular, utilities, and pipes

#Finishing grades: inlet, outlet, and surface layer

#Finishing grades: inlet, outlet, and surface layer

#Post-construction

#Post-construction

The first three categories of construction process are fundamentally the same for all ground-level LID types. For example, the STEP-recommended processes for excavation do not differ between practice type: excavation is excavation, whether it is for a bioretention or a permeable paver facility.

Stages 1-3 and 5 of the LID construction process are fundamentally similar for all '''surface-level LID''' types. To illustrate, STEP's recommended processes for excavation do not differ depending on the practice type. Excavation is excavation, whether it is for a bioretention garden or a permeable paver parking lot. On the other hand, stage 4 sub-tasks will vary substantially from practice to practice, as do some sub-tasks in stage 3. The following paragraphs give a brief explanation of each over-arching stage.
