Yes X No (If no, explain in Remarks.) Are Vegetation Soil or Hydrology significantly disturbed? Are "Normal Circumstances' present? Yes X No Are Vegetation Soil or Hydrology naturally problematic? (If needed, explain any answers in Remarks.) SUMMARY OF FINDINGS — Attach site map showing sampling point locations, transects, important features, etc. Hydrophytic Vegetation Present? Yes X No Is the Sampled Area Hydric Soil Present? Yes X No within a Wetland? Yes x No Wetland Hydrology Present? Yes X No Remarks: Wetland criteria not met as per the 1987 US Army Corp of Engineers Wetland Delineation Manual and the Gulf Coast Plain Regional Supplement. According to the Antecedent Precipitation vs Normal Range based on NOAA's Daily Global Historical Climatology Network, the site conditions were normal at the time of the field work.
