PRE-EXISTING INVENTORIES No per -existing inventories have been recorded on Parcel. 962700032, SLADE 962700032 LSWC JANUARY 2017 Page 13 The USFWS Wetland Inventory (WTI) did not identify wetlands on the parcel. The Jefferson County Map Data Base does not indicate a wetland on the parcel. METHOD AND APPROACH A 2 Level Assessment was used to identify, classify and delineate the wetlands on Parcel 962700032. The first level of assessment included review of existing information was conducted to develop background knowledge of physical features, and to identify the potential for wetland occurrence on the parcel. The resource documents available for preliminary review of the site conditions included: USDA Soil Conservation Service (SCS), "Soil Survey of Jefferson County Area Washington", 2013 and 1994, Jefferson County aerial photography, and Jefferson County Planning Department data. The second level of assessment included on-site investigation to determine the presence of wetlands and upland sites. On-site investigation determined and verified the wetlands and their location based on the three -factor approach involving indicators of hydrophytic vegetation, hydric soils and wetland hydrology as presented in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys and Coast Region (Version 2.0), May 2010. Hydric soils are classified using Filed Indicators of Hydric Soils in the United States, Version 2.0, 2010. The wetlands are classified as to category using the Washington State Wetland Rating System for Western Washington -October -2014, Effective January 2015, Washington State Department of Ecology's Publication No. 03-06-029 and applicable Rating Forms Effective January 1, 2015. WETLAND Wetland Boundary Two wetlands have been identified on the Parcel 962700032. Delineations: Both wetlands were delineated on the ground and identified as Wetland 9627000321-A and Wetland 9627000321-B and will be referred as Wetland A and Wetland B respective in this document (Exhibit I, Appendix A). Both wetlands were delineated on the parcel and a compass traverse was conducted to determine their location and size on the parcel. The larger part of Wetland B is on abutting Parcel 962700031. Wetland B on Parcel 962700031 was delineated in February 2016 but was not traversed or surveyed at the time. The wetland boundaries on Parcel 962700032 are marked with orange whips and flagging identifying station and wetland boundaries. Wetland B is located on the south side of the Parcel and Wetland A is on the north side of the Parcel. Wetland The wetlands were identified as separate wetlands as they are 160 feet apart and Criteria: have their own separate contributing basins. Each wetland is larger than the areas that occur on the parcel. Wetland A is 0.1 acre in size and Wetland B is 03 acres. Both wetlands are situated in what essentially glacial depressional SLADE 962700032 LSWC JANUARY 2017 Page 14 landforms much like glacial kettles as are exhibited below in Exhibit I for Wetland B on Parcels 962700031 and 962700032. Wetland B discharges intermittent overflows to a smaller abutting basin to the east. The intermittent discharge from Wetland B is unidirectional down -gradient, through a narrow saddle in the ridge between the two basins. The saddle is 12 feet higher than the bottom of the smaller basin. The elevated ridge between the two basins and the EXHIBIT H LANDFORM BASINS Sim? Cross Soction of Basim SSI RL� 962700032 36270063s & Basle � 4 Basin a r 0 t7 It114MlD+11d �� N 9s2rnaosa Intermittent flow from Basin B to the smaller enclosed basin are the main criteria determining that the separation of the two Basins. Wetland A on Parcel is in an enclosed basin that appears to have no outlet. Wetland A has a larger contributing basin Vegetation — Both wetlands were timber harvested in 2006 and have never returned to a commercial forest cover and consists of Alnus rubra (red alder) emergent and shrub vegetative cover shown in Exhibits III and IV Below. The main emergent although it does not meet the 'A acre or more than 10% cover requirement, consists of Carex obnupta (slough sedge) species. Shrubs are dominantly Rubus procerus (Himalayan blackberry), Rubus spectabilis (salmonberry), Salix scouleriana (Scouler willow), Salix lucida (Pacific willow), and Spiraea douglasii (Douglas spirea) and Crataegus douglasii (black hawthorn). While most Pacific, Sitka, and Scouler's willows and black hawthorn are considered shrubs a few of the willows and black hawthorn within the wetland boundary meets the definition of trees because they are 3 inches or greater in SLADE 962700032 LSWC JANUARY 2017 Page 15 diameter at breast height (DBH), regardless of height'. Site specific plot data for Wetland A and B is located in Appendix II. The dominant measureable trees in Exhibit III — Inundated area of Wetland A showing dense cover of willow and hardback. This Photo was taken between delineated stations 4 and 5. Exhibit IV — The very north point of Wetland B showing inundated area with slough sedge and saturated area supporting salmonberry and red alder. Only the east side of the wetland boundary on Parcel 962700032 supports slough sedge. Slough sedge does not meet 10% of the entire wetland the wetlands are red alders. Most of the trees are two or three trunks or have some type of trunk curvature. In February 2006 nine red alder selected were measured within the boundary of Wetland B. These red alders averaged 9.2 inch DBH (range from 5.9 to 12.5 inch DBH) with an average of age of 42.8 years (range from 29 to 62 years). These trees do not meet the requirements of being one contiguous (1) acre of mature forest as defined in the paragraph above. Soils — Although the soil maps show that the soils on Parcel 962700032 are the Clallam Series but in actuality the Sinclair Series (Sinclair gravelly sandy loams) are on the upland areas of the Parcel. The Sinclair soils are moderately deep moderately well drained soil with fine sandy loam mineral surfaces with gravelly and very gravelly sandy loans subsurface and subsoils. The soils have a compact and weakly cemented horizon (soil layer) starting at or below 25 inches. The wetlands have a Sinclair wet phase gravelly sandy loam surface and subsurface horizons with either gravelly sandy loam subsoils or silt loam or silty clay loam subsoils. These soils ranged from very dark brown to very dark grayish brown surfaces over laying grayish brown to very dark gray to very dark brown or greenish gray subsoils. Common prominent and distinct redoximorphic features in all the soils start within the upper 12 inches of the soil surfaces.

The soils on the wetland on Parcel 962700032 meet the hydric soil field indicator AI I (Depleted Below Dark Surface).z Hydrology - The wetlands are depressional wetlands as defined by the HGM Classification of Wetlands in Western Washington. Both wetlands have very small contributing drainage basins (Figure 2, for each wetland classification) (Appendix H &III for both wetlands in each rating system. Precipitation is the dominant source of waters in Wetland A and B. Because of the amount of inundation in both wetlands at the time of the field investigation it is expected that during any given year some portion of each wetland is permanently inundated as are part seasonally inundated and other areas of the wetlands are saturated. The hydroperiods are not exhibited on aerial photos since hydroperiods sites are variable and dense leaf cover prevents being able to distinguish the sites and delineate them on the photo. Exhibit IV on Page 6 shows an area of Wetland B at maximum inundation. Photo was taken in February of 2016.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? �li� ' ! !■er��.a�aa-ira��fliR]l�I.liilYiS! mit s!f 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)?

If it is Saltwater Tidal Fringe it is an 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. NO - go to 3 U96 •Pl......_.,_.kit! .,.._...:_. Pints 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 anytime of the year) at least 20 ac (8 ha) in size; .At least 30% of the open water area is deeper than 6.6 ft (2 m). NO-goto4 *96 4. Does the entire wetland unit meet all of the following criteria? _The wetland is on a slope (slope can be verygradual), _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 banks, The water leaves the wetland without being impounded. NO-goto5i-3 Slope . NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? _The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, _The overbank flooding occurs at least once every 2 years.

NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. YES - The wetland class is Depressional Is the entire wetland unit located in a very fiat 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 WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN TIME UNIT (make a rough sketch to help you decide). Use the following; table to identify the appropriate class to use for the rating system ii 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. Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than Z HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. 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 WHICH 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.
