''INSERT YOUTUBE LINK: https://www.youtube.com/watch?v=Ng_s2ErvPqk&t=58s <br>''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:'''#Backfill material from outside of the LID facility to avoid compaction and sediment entering the facilities. Use a slinger truck if possible.#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.
