_______________ 

1 Impact calculations are based on a 30-foot-wide ROW that will be operationally maintained through forested wetlands, converting to scrubshrub or emergent wetland. 

 Scrub-shrub and emergent wetlands will be allowed to naturally revegetate. 

2 Temporary ROW calculations are based on a 75-foot construction ROW and acreages of additional temporary workspace. 

3 Impacts to vegetation and wetland functions are 0 because the HDD construction impacts will result in no surface impacts. 

4 Feature crosses both the centerline and aboveground facilities or access roads; acreages have been split between respective project areas. 

*Wetland impacts are less than 0.001 acre and per rounding resulted in zero impacts in the table 

PEM = Palustrine emergent 

PSS = Palustrine scrub-shrub 

PFO = Palustrine forested 

POW = Palustrine open water 

N/A = Not Applicable
