nonwetlands, the entire area is nonwetlands. If both wetlands and non- 

 wetlands are present, identify observation points that represent wet- 

 land boundaries on the base map. Connect these points on the map by 

 generally following contour lines to separate wetlands from nonwet- 

 lands. Walk the contour line between transects to confirm the wetland 

 boundary. Should anomalies be encountered, it will be necessary to 

 establish short transects in these areas, apply the procedures de- 

 scribed in STEP 20f_, and make any necessary adjustments on the base 

 map.

66. In some cases, especially for large projects, adequate information 

 may already be available (Section B) to enable a wetland determination for a 

 portion of the project area, while an onsite visit will be required for the 

 remainder of the area. Since procedures for each situation have already been 

 described in Subsections 1 and 2, they will not be repeated. Apply the 

 following steps: 



• STEP 1 - Make Wetland Determination for Portions of the Project Area 

 That Are Already Adequately Characterized. Apply procedures described 

 in Subsection 1. When completed, a DATA FORM 1 will have been com- 

 pleted for each community type, and a map will have been prepared 

 identifying each community type as wetland or nonwetland and showing 

 any wetland boundary occurring in this portion of the project area. 

 PROCEED TO STEP 2. 



• STEP 2 - Make Wetland Determination for Portions of the Project Area 

 That Require an Onsite Visit. Apply procedures described in Subsec- 

 tion 2. When completed, a DATA FORM 1 will have been completed for 

 each plant community type or for a number of observation points (in- 

 cluding wetland boundary determinations) . A map of the wetland (if 

 present) will also be available. PROCEED TO STEP 3. 



• STEP 3 - Synthesize Data. Using the maps resulting from STEPS 1 

 and 2, prepare a summary map that shows the wetlands of the entire 

 project area. CAUTION: Wetland boundaries for the two maps will not 

 always match exactly. When this occurs, an additional site visit will 

 be required to refine the wetland boundaries. Siyice the degree of
