Construction stages[edit]

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

  1. Pre-construction
  2. Excavation and grading
  3. Backfill granular, utilities, and pipes
  4. Finishing grades: inlet, outlet, and surface layer
  5. Post-construction

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.

Pre-construction[edit]

Pre-construction activities set the stage for the successful construction of an LID practice. The pre-construction stage begins by field-verifying the design when it is at the 90% completion stage.

Excavation and grading[edit]

Backfill granular, utilities, and pipes[edit]

Finishing grades and surface layer[edit]

Post-construction[edit]
