ADDITIONAL COMMENTS:
AESI was onsite for a weekly TESC visit. No discharge was observed at the time of visit. AESI took a water sample from
the 111th Ave swale outfall. The turbidity of the water came back at 6.01 NTU. This is in compliance with the SWPP.
Exposed soils were observed, but AESI noted that landscapers were onsite and work on driveways had begun.
