Are climatic/hydrologic conditions on the site typical for this time of year? Yes ✓ No (If no,explain in Remarks.)
Are Vegetation Soil ,or Hydrology significantly disturbed? No Are"Normal Circumstances"present? Yes ✓ No
Are Vegetation Soil ,or Hydrology naturally problematic? No (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 No Is the Sampled Area
Hydric Soil Present? Yes No within a Wetland? Yes ✓ No
Wetland Hydrology Present? Yes No
Remarks:
Wetland data point in a depression in the central portion of the survey area that appears to have been previously flooded seasonally. This data point is
paired with upland data point DP-El a.
