The storage reservoir layer holds and directs the stormwater into the underlying/native soils. The LID facilities, if applicable, should be filled with uniformly graded, washed stone (20 mm – 50 mm) that provides 30 to 40% void space.

‘’’Construction steps:’’’

  1. Backfill material from outside of the LID facility to avoid compaction and sediment entering the facilities. Use a slinger truck if possible.
  2. Place the material to the elevation and thickness as per the design specifications.

‘’’Key Inspection Points:’’’

  • Material arrival to the site:
    • Check chain of custody
    • Verify it meets specifications as per design
    • Verify no debris or fines within the aggregate (it’s a washed stone)
  • Granular material should be 19 - 50 mm clear stone or as per design. See Aggregates for further details.
  • Installed aggregate is at the correct elevation as per design.

‘’’Mistakes to Avoid:’’’

  • Accepting material that does not meet design requirements and specifications.
  • Installing material with heavy equipment from the inside of the LID facility
  • Installing frozen aggregate. Do not install frozen aggregate
  • Leaving heavy equipment (excavator) for long periods of time within the LID facility.
