Your wetlani unit seems to be difficult to clossify and probably contains severel difterent HGM dasses. For <br />example, sccps at the besc of a slope may grade into e rivttine Ooodplein, or e small str'eam within a deprcssional <br />wetlend haz a zonc oCllooding along its sidcs. GO IIACK AND IDENTIFY WHICH OF THE HYDROLOGIC <br />REGIMES DESCRIDED IN QUESTIONS 1-7 APPLY TO DIFFEREM AREAS IN THE IJNIT (make a rough <br />skctch to help you decide). Usc the following table to identify the appropriate class to use for the reling system if <br />you have several HGM classes within your wetland. N01'E: Uu this table only if ihe cless that is recommended in <br />ihe second column reprcsents 10% or morc of �he total eren of the weUand boing rsted. If Ihe area of the second <br />clnss is less than 10% of the uni4 clossify the wetlend using �he cless that rcprcsent more thon 90%of ihe total erea. <br />If you arc unable still to dctcrminc which otthe abovc critcria epply to your wetlend, or you have morc then 2 HGM <br />classcs within n wctland boundary, classify thc weqend es Depresslon�l for lhe reting. <br />Wetland Rating Form - Westem Washinglon <br />
