SGAT Feature Type
Attribute Information
Stream segment corridor polygon
Phase 2 (step 7.7) – indicating the stream sensitivity
* note: the corridor must be segmented if the Phase 2 reach was
segmented prior to attributing Phase 2 data to it.
Export Code: STR_SENSIT
Phase 2 (Step 7.1 and 7.2) – separately indicating if the channel
adjustments of degradation or aggradation are major adjustments (fair or
poor conditions – scores of 1-5 are poor, 6 – 10 are fair) and the

Use the “Sensitivity” data layer to display the Phase 2 sensitivity rating assigned to each
segment/reach. Categorize by “Unique Value”. Set the “Value Field” to
“Phase2MappingExport.STR_SENSIT”. Add all relevant values.
Unique Value in Symbology
Change the “Sensitivity” polygon symbols to the blue, yellow, peach, orange and red shaded fills
symbols for “Very Low”, “Low”, “Moderate”, “High”, “Very High”, and “Extreme”,
respectively.
