ADDITIONAL COMMENTS:
While onsite, AESI observed some silt fencing knocked down and sediment trackout. AESI took a water sample from the
outfall swale on 111th Ave. The turbidity came back at 38 NTU and 7.0 pH. AESI notified the contractor and
recommended repairing the silt fencing around the perimeter of the site, adding additional silt socks in the catch basins
off of 111th Ave, sweeping the roads to clear the sediment, and adding straw over exposed soils.
