The delineation was performed to identify the location of wetlands north and west of the property, and calculate the associated wetland buffers required by the latest version of the Mason County Resource Ordinance. The field visits were completed on February 19th and April 21 st, 2008 The subject property is located in the NE '/4 of Section 29, Township 23 North, Range 01 West WM(Figure 1 Vicinity Map). The parcel is 0.76 acre in size. For the purposes of federal, Washington State, and Mason County jurisdictional oversight, methodology used for the wetland delineation is consistent with the wetland definition provided in paragraph 25a of the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology, 1997). The sections below provide: (1) an introduction to the site; (2) a description of methods used in the field delineation; and, (3)technical results. GENERAL SITE CONDITIONS The parcel is roughly rectangular in shape, oriented east to west. The parcel is accesse via Old Belfair Highway, and residential parcels of similar size surround the parcel to the east, north and south. Large undeveloped parcels containing a Depressional-riverine wetland system associated with several channels, border the parcel to the west. This large wetland system is characterized by a diverse vegetation community, consisting of an overstory of red alder and western red cedar, with an understory consisting of stinging nettle, salmonberry, water parsley, and skunk cabbage. The large wetland system is located approximately 190 feet from the property, at the nearest point. A sloped wetland area slightly encroaches into the northern portion of the western side of the property, and drains northwesterly, into the large riverine wetland system west of the parcel. This wetland has already been investigated in a previous report by TWC prepared in February, 2008, and meets criteria for a Category III Wetland and requires an 80' PO Box 2854 Belfair,Washington 98528-Cell Phone 360-620-0618.Office Phone 360-372-2421-boad40@peoplepc.com Moore Wetland Delineation TWC08-W22 April,2008 Page 2 of 17 buffer with additional 15-foot building setback for'High Impact Development. A detailed evaluation of the slope wetland is also covered in this report. The wetland is characterized by a vegetative community of salmonberry, cascara, reed canarygrass, coltsfoot, creeping buttercup, and slough sedge. Adjacent upland vegetation within the parcel consists of Japanese knotweed, himilayan blackberry, coltsfoot and swordfern. Topography throughout the parcel is generally flat, with the exception of a moderate gradient slope northwesterly, down toward the wetland. The slope becomes steeper further west.along the-property. METHODOLOGY Review ofExisting Information Consistent with procedures detailed in the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology, 1997) (1997 Manual), preliminary information was gathered on the project site prior to the field review and delineation. General information sources included: United States Geological Service (USGS) topographic maps, 1974 United States Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI) maps, the Soil Survey of Mason County Area, Washington(USDA, 1951), and Mason County's critical areas regulations. Field Delineation Methodology used for wetland delineation was consistent with the technical approaches articulated in the 1997 Manual. This document is the wetland delineation manual that is used in determining wetland areas when applying state and local government regulations under the Shoreline Management Act and the Growth Management Act in Washington State. The extent and location of suspect wetlands were determined during field work performed on February 19'h and March 21", 2008. Field work was conducted under cloudy skies with an ambient temperature ranging between 45 and 55 degrees Fahrenheit. The time of year and recent precipitation history were considered in assessing the extent of the suspect wetland presumed to exist on site. Specific field methodology used in determining the extent and location of wetland areas include: 1. As part of the initial project site reconnaissance, the site was walked to determine the general extent and location of potential wetland areas; 2. Wetland and upland sample plots were established in the identified potential wetland areas and in the adjacent upland area; and 3. Wetland boundaries were delineated with flagging by noting localized topography and vegetation patterns and comparing parameters of hydrology, soil, and vegetation with data collected at the wetland and upland sample plots.

Data collected at each sample plot were entered onto a Routine Wetland Determination Data Form (Washington State Department of Ecology 1997). Copies of data forms for each sample plot are provided in Appendix A. BACKGROUND INFORMATION Mason County Soil Survey The soil survey of Mason County indicates two onsite soil types, (USDA, 1951): Soil type one has been identified as: Saxon silt loam, 5 to 15 percent slopes (Sa):The Saxon series consists of friable, well-drained, brown, silty soils on the uplands. They have developed from Vashon glacial lake sediment similar to that of the Kitsap soils. Surface drainage is well developed, internal drainage is medium, and the moisture- holding capacity is good. The rainfall is 45 to 60 inches a year. The vegetation is a dense forest of fir, cedar, and alder, with a dense undercover of salal, vine maple, bracken fern, and sword fern. Saxon soils differ from the Kitsap soils in having browner surface soil and less dense subsoil,and in containing shot. The second soil type is mapped within the western portion of the parcel, and is identified as Norma silt loam, 0 to 3 percent slopes (Ne).-The Norma series consists of poorly drained,very dark, highly organic soils in upland depressions. They have developed from coarse sandy drift under the influence of excessive moisture. The rainfall is 45 to 60 inches a year. The vegetation is alder, vine maple, willow, spirea, wild rose, skunkcabbage, and, in scattered marshy areas, reeds and sedges. These soils occur in association with the Alderwood. Everett,and Indianola soils. Norma soils do not have the finetextured subsoil typical of the Bellingham series, nor the very gravelly subsoil of the McKenna series, nor the iron oxide cementation of the Edmonds series. National Wetlands Inventory The USFWS NWI map (online wetlands mapper) does not map the identified wetlands near or within the approximate parcel location. The nearest mapped wetland is located 1000 feet southeast of the subject parcel(Figure 3. National Wetland Inventory Map). Department of Natural Resources Water Resource The Department of Natural Resources Water Resource Map shows no streams in vicinity of the subject parcel. The nearest stream is identified as the Union River, and is mapped approximately 1000 feet west of the parcel (Figure 5. DNR Stream Map).

The wetland receives water from a culvert that drains surface runoff from Old Belfair Highway, and is also hydrologically supported by a fluctuating water table. The culvert is located at the easternmost point of the wetland. The wetland slopes downward northwesterly to eventually tie into a large riverine wetland system, west of the parcel. The subject wetland within the parcel meets Department of Ecology criteria for a Slope Wetland, because water generally moves one direction (northwesterly), is on a slope, and water leaves the wetland into the riverine system without being impounded. Detailed information about the wetland vegetation, hydrology and soil characteristics are addressed below. 3 �, r� "„�� .ale � Ju +! /� >. •l ;;I "-'L- } # .,� a Photo 1.

Easternmost point of wetland within property,occupied primarily by reed canarygrass (Phalarzs arundinacea,FACW) Ve eg tation The vegetation community is comprised of a scattered overstory of red alder (Alnus rubra, FAC), with a shrub community of salmonberry (Rubus spectabilis, FAC+) and lesser amounts of spirea (Spiraea douglasii, FACW). The herbaceous layer consists of reed canarygrass (Phalaris arundinacea), creeping buttercup (Ranunculus repens, FACW), piggyback plant (Tolmiea menziesii, FAQ, and slough sedge (Carex obnupta, OBL). The upland vegetation within the parcel includes an overstory of red alder (Alnus rubra, FAQ. Understory species consist of Japanese knotweed (Polygonum cuspidatum, FACU), himilayan blackberry (Rubus discolor, FACU), swordfern (Polystichum munitum,FACU), salal(Gaultheria shallon, FACU), and creeping buttercup(Ranunculus repens,FACW). Soils Both test pits excavated in the wetland area revealed a two-layer profile. The upper layer consists of silt with matrix chroma 10YR 3/1 to a depth of six to eight inches. The lower is similar to the upper layer with the exception of commonly present, faint, medium sized mottles with matrix chroma 10YR 4/4. This soil profile is consistent with the mapped soil type, Norma silt loam (Ne). Norma silt loam (Ne) is listed as a hydric soil on the 2007 National Hydric Soils List. Wetland hydric soils are indicated by a low-chroma PO Box 2854 Belfair,Washington 98528-Cell Phone 360-620-0618.Office Phone 360-372-2421-boad40@peoplepc.com Moore Wetland Delineation TWC08-W22 April,2008 Page 6 of 17 (equaling one) in the wetland test pits, with mottles, and soil profile consistent with a listed hydric soil type. The soil profiles observed in known upland test pits were consistent with the mapped soil type, Sa-Saxon silt loam. Upland test pits also exhibited a two-layer soil profile of silt loam to eighteen inches deep. The upper layer consists of silt loam approximately eight inches deep of matrix chroma 10YR 3/3. The lower profile contained less gravel with a matrix chroma of 10 YR 6/3. No hydric soil indicators were present in upland soil test pits. Hydrolq& Hydrology was indicated by FAC-neutral vegetation, drainage patterns, mapped hydric soils, and water-stained leaves. In addition, the test pits revealed soil saturation and free water in the test pits during the non-growing season. On the day of the field visit, the wetland was inundated up to six inches. Upland test pits showed no indicators of wetland hydrology. Depressional Wetland(Outside of Property) The large wetland outside of the parcel is associated with a riverine wetland system to the north, but is identified in this portion as a depressional wetland due to the overall hydrology regime coming from several different sources, including a fluctuating water table, hillside seeps, surface runoff from surrounding topography, in addition to overbank flooding from several small channels within the central portion of the wetland. The wetland is located 190 feet west of the subject property, at the nearest point. Based on topography patterns and the Mason County Soil Survey (See Figure 4. Soil Survey), the entire wetland appears to occupy approximately 20 acres. The portions of the wetland within 250 feet are flagged with pink flagging labeled WETLAND DELINEATION.

The upland vegetation in areas adjacent to the wetland include an overstory of big leaf maple (Ater macrophyllum, FACU), red alder(Alnus rubra, FAC) and western red cedar (Thuja plicata,FAC). Understory species consist of Indian plum(Oemleria cerasiformis, FACU), salmonberry (Rubus spectabilis, FAC+), stinging nettle (Urtica dioica, FAC), PO Box 2854 Belfair,Washington 98528-Cell Phone 360-620-0618.Office Phone 360-372-2421•boad40@peoplepc.com Moore Wetland Delineation TWC08-W22 April,2008 Page 9 of 17 himilayan blackberry (Rubus discolor, FACU), swordfern (Polystichum munitum, FACU), and bleeding heart(Decentra formosis, FACU). Soils Both test pits excavated in the wetland area revealed a single layer profile of muck to 12 inches deep. Wetland hydric soils are indicated by a low-chroma (equaling one) in the wetland test pits. In addition, a sulfidic odor was present during test pit excavation. The Mason County Soil Survey maps this area to contain Norma Silt loam, which is listed on the 2008 National Hydric Soils list as a hydric soil. The soil pits exhibited a soil profile that had a high content of organic matter in low-chroma soils, similar to Norma silt loam. It is likely that areas within the wetland, beyond the location of the data plots, consist of soil characteristics similar to the mapped soil type. The soil profiles observed in known upland test pits were consistent with the mapped soil type, Sa-Saxon silt loam. Upland test pits also exhibited a two-layer soil profile of silt loam to eighteen inches deep. The upper layer consists of silt loam approximately eight inches deep of matrix chroma 10YR 3/3. The lower profile contained less gravel with a matrix chroma of 10 YR 6/3. No hydric soil indicators were present in upland soil test pits. Hydrology Hydrology was indicated by FAC-neutral vegetation, drainage patterns, mapped hydric soils, and water-stained leaves. In addition, the test pits revealed soil saturation and free water in the test pits during the non-growing season. On the day of the field visit, the wetland was inundated up to six inches. Upland test pits showed no indicators of wetland hydrology. WETLAND EVALUATION The wetland within the property meets criteria for a Slope wetland per Washington State Wetland Rating System for Western Washington (Hruby 2004) for the purposes of rating.

NOTES: Revised 4197 APPENDIX B Soil Survey Text SAXON SERIES The Saxon series consists of friable, well-drained, brown, silty soils on the uplands. They have developed from Vashon glacial lake sediment similar to that of the Kitsap soils. Surface drainage is well developed, internal drainage is medium, and the moisture- holding capacity is good. The rainfall is 45 to 60 inches a year. The vegetation is a dense forest of fir, cedar, and alder, with a dense undercover of salal, vine maple, bracken fern, and sword fern. Saxon soils differ from the Kitsap soils in having browner surface soil and less dense subsoil, and in containing shot. Saxon silt loam, 5 to 15 percent slopes (Sa).-This soil occurs on rolling or gently rolling benches near Belfair. The surface soil is friable and moderately granular, brown silt loam, 8 to 10 inches thick. It is slightly acid and contains many roots and very little shot. This is underlain by a pale-brown, friable silt loam, which at depths between 15 and 20 inches grades to a friable to firm silt loam subsoil having weak, subangular blocky structure. Yellowish-brown'-stains occur along root channels. Below a depth of 30 inches, the subsoil grades to slightly compacted, stratified, and platy fine sand and silt, which continue to depths of several , more feet. The slight compaction in this material does not restrict movement of moisture or growth of roots. The soil is deep, friable, and permeable; it has a good capacity to hold available moisture. Use and suitability.-Much of this soil has been cleared and is used mainly for hay, grain, and pasture. Vegetables are grown for local markets and for home use on many small, intensively farmed garden plots. Yields of crops compare favorably with those on the best upland soils, and they are only slightly less than those obtained on the better flood-plain soils. Though the soil is moderately fertile, nitrogen and organic matter must be maintained through additions of barnyard manure, or through use of green- manure crops. Commercial nitrogen fertilizer benefits garden crops and, when it is used with phosphate, additional benefits are obtained. This soil is in capability subclass We and in site class 3 for Douglas-fir. NORMA SERIES The Norma series consists of poorly drained, very dark, highly organic soils in upland depressions. They have developed from coarse sandy drift under the influence of excessive moisture. The rainfall is 45 to 60 inches a year. The vegetation is alder, vine maple, willow, spirea, wild rose, skunkcabbage, and, in scattered marshy areas, reeds and sedges. These soils occur in association with the Alderwood. Everett, and Indianola soils. Norma soils do not have the finetextured subsoil typical of the Bellingham series, nor the very gravelly subsoil of the McKenna series, nor the iron oxide cementation of the Edmonds series. Norma silt loam, 0 to 3 percent slopes (Ne).-This soil occurs as small areas scattered throughout the eastern two-thirds of the county. At the surface is a thin, organic mat of leaves, twigs, and moss. Under this litter is a highly organic, friable, dark- gray (nearly black when moist) silt loam, 5 to 8 inches thick. This grades to a friable, weakly granular, dark grayish-brown, or dark-gray and olive-gray fine sandy loam, which ranges from 4 to 12 inches in thickness. This last-named material contains much less organic matter than the surface soil and is faintly mottled with reddish brown and yellowish brown. Below this layer is the subsoil, a massive, friable, slightly compact, light brownish-gray loamy sand, moderately mottled with reddish brown and reddish yellow. Mottling becomes less intense and the texture becomes coarser with depth. There are a few reddishbrown lenses, cemented by iron, in the subsoil. The substratum, consisting of compact, light-gray gravelly sandy drift, is at depths of 24 to 32 inches. The soil is saturated with water in winter and spring. In dry summers the water table drops below 3 feet. To be suitable for crops, the soil must be drained. Use and suitability.-A small acreage has been drained, cleared, and used for agriculture. This land is nearly always farmed along with other soils. Partly cleared, drained areas are used for pasture. Unless drainage is adequate and pasture grasses are maintained, undesirable plants soon take over. This soil is more easily drained than many of the other basin soils because its subsoil is more permeable and allows the use of open drainage ditches. This soil is fertile and productive if properly drained. Management is similar to that of the Bellingham silt loam. This soil is in capability subclass IIIw; it is fair for mixed forests consisting of red alder, Oregon-maple, willow, hemlock, spruce, and redcedar.

Wetland Type Wetland Class Estuarine De ressional Natural Heritage Wetland Riverine —Bog Lake-fringe Mature Forest X Sloe X Old Growth Forest Flats Coastal Lagoon Freshwater Tidal Interdunal None of the above Does the wetland being rated meet any of the criteria below? If you answer YES to any of the questions below you will need to protect the wetland according to the regulations regarding the special characteristics found in the wetland. Check List for Wetlands that Need Special Protection, YES NO and That are Not Included in the Rating SP1. Has the wetland been documented as a habitat for any Federally listed Threatened or Endangered plant or animal species (TIE species)? For the purposes of this rating system, "documented" means the wetland is on the appropriate X state or federal database. SP2. Has the wetland been documented as habitat for any State listed Threatened or Endangered X plant or animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. SP3. Does the wetland contain individuals of Priority species listed by the WDFW or the state? X SP4. Does the wetland have a local significance in addition to its functions? For example, the X wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydroaeomorphic Class of the wetland being rated The hydrogeomorphic classification groups wetlands in to those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form—western Washington(11/04) Page 1 of 8 Classification of Vegetated Wetlands for Western Washington Wetland Name: Moore Wetland Date: 2/28/08 1. Are the water levels in the wetland usually controlled by tides(i.e. except during floods)? NO—go to 2 YES—the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt(parts per thousand)? YES—Freshwater Tidal Fringe NO—Saltwater Tidal Fringe(Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term"Estuarine"wetland is kept. Please note, however,that the characteristics that define Category I and II estuarine wetlands have changed(see p. ). 2. Is the topography within the wetland flat and precipitation is only source(>90%)of water to it. NO—go to 3 YES—The wetland class is Flats If your wetland can be classified as a"Flats"wetland, use the form for Depressional wetlands. 3. Does the wetland meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of open water(without any vegetation on the surface)where at least 20 acres(8ha)are permanently inundated(ponded or flooded); At least 30%of the open water area is deeper than 6.6(2 m)? NO—go to 4 YES—The wetland class is Lake-fringe(Lacustrine Fringe) 4. Does the wetland meet all of the following criteria? x The wetland is on a slope(slope can be very gradual). x 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. x The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and shallow depressions or behind hummocks(depressions are usually<3 ft diameter and less than I foot deep). NO—go to 5 YES—The wetland class is Slope 5. Is the wetland in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river? The flooding should occur at least once every two years, on the average,to answer"yes". The wetland can contain depressions that are filled with water when the river is not flooding. NO—go to 6 YES—The wetland class is Riverine 6. Is the wetland in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. 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 wetland located in a very flat area with no obvious depressional and no stream or river running through it and providing water. The wetland 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 seems to be difficult to classify. 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. Sometimes we find characteristics of several different hydrogeomorphic classes within one wetland boundary. Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. 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 being rated. If the area of the second class is less than 10% classify the wetland using the first class.

Check List for Wetlands that Need Special Protection, YES NO and That are Not Included in the Rating SP 1. Has the wetland been documented as a habitat for any Federally listed Threatened or Endangered plant or animal species (TIE species)? X For the purposes of this rating system, "documented" means the wetland is on the appropriate state or federal database. SP2. Has the wetland been documented as habitat for any State listed Threatened or Endangered plant or animal species? For the purposes of this rating system, "documented" means the X wetland is on the appropriate state database. SP3. Does the wetland contain individuals of Priority species listed by the WDFW or the state? X SP4. Does the wetland have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or X in a local management plan as having special significance. To complete the next Dart of the data sheet you will need to determine the Hydro eg omorphic Class of the wetland being rated. The hydrogeomorphic classification groups wetlands in to those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form-western Washington(11/04) Page 1 of 8 Classification of Vegetated Wetlands for Western Washington Wetland Name: Moore Wetland Date: 2/15/08 1. Are the water levels in the wetland usually controlled by tides(i.e. except during floods)? NO—go to 2 YES—the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES— Freshwater Tidal Fringe NO—Saltwater Tidal Fringe(Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. Is the topography within the wetland flat and precipitation is only source(>90%) of water to it. NO—go to 3 YES—The wetland class is Flats If your wetland can be classified as a"Flats" wetland, use the form for Depressional wetlands. 3. Does the wetland meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of open water(without any vegetation on the surface)where at least 20 acres(8ha) are permanently inundated (ponded or flooded); At least 30% of the open water area is deeper than 6.6 (2 m)? NO—go to 4 YES—The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the wetland meet all of the following criteria? The wetland is on a slope (slope can be very gradual). 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? NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and shallow depressions or behind hummocks(depressions are usually<3 ft diameter and less than I foot deep). NO—go to 5 YES—The wetland class is Slope 5. Is the wetland in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river? The flooding should occur at least once every two years, on the average, to answer"yes". The wetland can contain depressions that are filled with water when the river is not flooding. NO—go to 6 YES—The wetland class is Riverine 6. Is the wetland in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. 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 wetland located in a very flat area with no obvious depressional and no stream or river running through it and providing water. The wetland 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 seems to be difficult to classify. 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. Sometimes we find characteristics of several different hydrogeomorphic classes within one wetland boundary. Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. 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 being rated. If the area of the second class is less than 10% classify the wetland using the first class. HGM Classes Within a Delineated Wetland Boundary Class to Use in Rating Slope+Riverine Riverine Slope+Depressional Depressional Slope+Lake-fringe Lake-frin e Depressional +Riverine along stream within boundary Depressional Depressional +Lake-fringe Depressional Salt Water Tidal Fringe and any other class of Treat as ESTUARINE under wetlands with special freshwater wetland characteristics If you are unable still to determine which of the above criteria apply to your wetland, or you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

I The wetland is relatively undisturbed(has no diking, ditching, filling,cultivation,grazing, and has less than 10%cover of non-native plant species. If the non-native Spartina sp ,. are only sppecies that cover more than 10%of the wetland,then the wetland should be given a dual rating(I/II). Cat.II The area of Spartina would be rated a Category II while the relatively undisturbed upper marsh with native species would be a Category 1. Do not,however,exclude the area of Spartina in determining the size threshold of 1 acre. Dual At least 3/4 of the landward edge of the wetland has a 100 ft. buffer of shrub,forest,or un-grazed Rating or un-mowed grassland The wetland has at least 2 of the following features: tidal channels,depressions with open water, 1/II or contiguous freshwater wetlands. SC2 Natural Heritage Wetlands (see p. 88) Natural Heritage wetlands have been identified by the Washington Natural heritage Program/DNR as either high quality undisturbed wetlands or wetlands that support state Threatened,Endangered,or Sensitive plant species. SC 2.1 Is the wetland being rated in a Section/Township/Range that contains a natural heritage wetland? (This question is used to screen out most sites before you need to contact WNHPIDNR.)

If you answer yes you will still need to rate the wetland based on its function. 1. Does the wetland have organic soil horizons(i.e. layers of organic soil), either peats or mucks,that compose 16 inches or more of the first 32 inches of soil profile? (See Appendix B for a field key to identify organic soils)? YES=go to question 3 NO=go to question 2 2. Does the wetland have organic soils, either peats or mucks that are less than 16 inches deep over bedrock,or an impermeable hardpan such as clay or volcanic ash, or that are floating on a lake or pond? YES=go to question 3 NO=is not a bog for purpose of rating 3. Does the wetland have more than 70%cover of mosses at ground level, AND other plants, if present,consist of the"bog"species listed in Table 3 as a significant component of the vegetation (more than 30%of the total shrub and herbaceous cover consists of species in Table 3)? YES=Is a bog for purpose of rating NO=go to question 4 NOTE: If you are uncertain about the extent of mosses in the understory you may substitute that criterion by measuring the pH of the water that seeps into a hold dug at least 16"deep. If the pH is less than 5.0 and the"bog"plant species in Table 3 are present,the wetland is a bog. 4. Is the wetland forested(>30%cover)with sitka spruce,subalpine fir,western red cedar,western hemlock, lodgepole pine,quaking aspen,Englemann's spruce,or western white pine. WITH any of the species(or combination of species)on the bog species plant list in Table 3 as a significant component of the ground cover (> 30%coverage of the total shrub/herbaceous cover)? Cat.

If you answer yes you will still need to rate the wetland based on its function. Old-growth forests: (west of Cascade Crest) Stands of at least two three species forming a multi-layered canopy with occasional small openings; with at least 8 trees/acre(20 trees/hectare) that are at least 200 years of age OR have a diameter at breast height(dbh) of 32 inches(81 cm or more). NOTE: The criterion for dbh is based on measurements for upland forests. Two-hundred year old trees in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW criterion is and"OR"so old-growth forests do not necessarily have to have trees of this diameter. Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80—200 years old OR have an average diameters(dbh)exceeding 21 inches(53 cm); crown cover may be less than 100%; decay, decadence,numbers of snags,and quantity of large downed material is generally less than that found in old-growth.
