Are climatic / hydrologic conditions on the site typical for this time of year? 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 No X within a Wetland? Yes No X
Wetland Hydrology Present? Yes No X
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 NOANs Daily Global Historical Climatology Network, the site conditions were
normal at the time of the field work.
