• <br /> Wetland name or number A <br /> 6. Is the entire wetland unit in a topographic depression in which water ponds,or is saturated to the surface,at <br /> some time during the year? This means that any outlet, if present,is higher than the interior of the wetland. <br /> ❑ NO-go to 7 YES-The wetland class is Depressional <br /> 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? <br /> The unit does not pond surface water more than a few inches.The unit seems to be maintained by high <br /> groundwater in the area.The wetland may be ditched,but has no obvious natural outlet. <br /> ❑ NO-go to 8 0 YES-The wetland class is Depressional <br /> 8.Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For <br /> example,seeps at the base of a slope may grade into a riverine floodplain,or a small stream within a <br /> Depressional wetland has a zone of flooding along its sides.GO BACK AND IDENTIFY WHICH OF THE <br /> HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT <br /> (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for <br /> the rating system if you have several HGM classes present within the wetland unit being scored. <br /> NOTE: Use this table only if the class that is recommended in the second column represents 10%or more of <br /> the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% <br /> of the unit; classify the wetland using the class that represents more than 90%of the total area. <br /> HGM classes within the wetland unit HGM class to <br /> being rated use in rating. <br /> Slope+ Riverine Riverine <br /> Slope+Depressional Depressional <br /> Slope+Lake Fringe Lake Fringe <br /> Depressional+Riverine along stream Depressional <br /> within boundary of depression <br /> Depressional+ Lake Fringe Depressional <br /> Riverine+ Lake Fringe Riverine <br /> Salt Water Tidal Fringe and any other Treat as <br /> class of freshwater wetland ESTUARIN E <br /> If you are still unable to determine which of the above criteria apply to your wetland,or if you have more than <br /> 2 HGM classes within a wetland boundary, classify the wetland as Depression&for the rating. <br /> NOTES and FIELD OBSERVATIONS: <br /> Wetland Rating System for Western WA:2014 Update <br /> Rating Form-Effective January 1,2015 4 WSDOT Adapted Form-March 2,2015 <br />
