NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. if it is Saltwater Tidal Fringe it is on Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. ,)- go to 3 YES - The wetland class is Flats Ifyour wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ,,._,The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; —At least 30/0 of the open water area is Bleeper than 6,6 ft (2 m). - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be verrygradual), .,%°._.The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a Swale without distinct banlcs, _' The water leaves the wetland without being impounded, NO - go to 5 ES The wetland class is Slope MOTE: Surface water does not pond in these type of wetlands except occasionally in very snxall and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). i. Does the entire wetland unit meet all of the following criteria? —The unit is in a valley, or strearn channel, where it gets inundated by overbank flooding from that stream or river, ,_._._The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number NO - go to 6 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding G. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the yeat•? This means that any outlet, if present; is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY W141CH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. if the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. f-iC�IV1 CIa5S�5!sM1lltillii iI�C1 W�tIs7ElCI 11 flit .' bLlryg r teC� `I IGM�Giass to use. in rat Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional+ Lake Fringe Depressional Riverine i- Lake Fringe Riverine Salt Water Tidaf Fringe and any other class of freshwater wetland Treat as ESTUARINE lfyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have rnore, than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the ra ting.
