ADDITIONAL COMMENTS:
While onsite, AESI noted that the contractor had installed silt fencing along the NW perimeter. AESI observed the silt
fence to need repairs in some areas around the site. AESI recommends repairing the silt fence around the perimeter and
replacing the silt socks in the catch basins. Conveyance channels may also be used to direct water to a sediment pond
until the gutters are installed. AESI took a water sample from the outfall swale on 111th Ave. The turbidity came back at
2 NTU and 6.0 pH.
