1. Ground Surface Condition/Vegetation Condition — assessment area condition metric
Check a box in each column. Consider alteration to the ground surface (GS) in the assessment area and vegetation structure
(VS) in the assessment area. Compare to reference wetland if applicable (see User Manual). If a reference is not applicable,
then rate the assessment area based on evidence of an effect.

[] A ['i A Not severely altered
B [] B Severely altered over a majority of the assessment area (ground surface alteration examples: vehicle tracks, excessive
sedimentation, fire -plow lanes, skidder tracks, bedding, fill, soil compaction, obvious pollutants) (vegetation structure
alteration examples: mechanical disturbance, herbicides, salt intrusion [where appropriate], exotic species, grazing,
less diversity [if appropriate], hydrologic alteration)
2. Surface and Sub -Surface Storage Capacity and Duration — assessment area condition metric
Check a box in each column. Consider surface storage capacity and duration (Surf) and sub -surface storage capacity and
duration (Sub). Consider both increase and decrease in hydrology. A ditch s 1 foot deep is considered to affect surface water only,
while a ditch > 1 foot deep is expected to affect both surface and sub -surface water. Consider tidal flooding regime, if applicable.
Surf Sub
[] A C'e A Water storage capacity and duration are not altered.
B B Water storage capacity or duration are altered, but not substantially (typically, not sufficient to change vegetation).
C C Water storage capacity or duration are substantially altered (typically, alteration sufficient to result in vegetation
change) (examples: draining, flooding, soil compaction, filling, excessive sedimentation, underground utility lines).

potentially overwhelming the treatment capacity of the wetland (water discoloration, dead vegetation, excessive
sedimentation, odor)
6. Land Use — opportunity metric (skip for non -riparian wetlands)
Check all that apply (at least one box in each column). Evaluation involves a GIS effort with field adjustment. Consider sources
draining to assessment area within entire upstream watershed (WS), within 5 miles and within the watershed draining to the
assessment area (5M), and within 2 miles and within the watershed draining to the assessment area (2M). Effective riparian buffers

F E F E F E >_ 20% coverage of maintained grass/herb
F F F F F F >_ 20% coverage of clear-cut land
