The Project Site is located within Section 24 of Township 29N and Range 2 West, in Jefferson County, Washington. The Project Site consists of three separate parcels (same parcel number) and is located approximately 0.13 miles south of Discovery Bay and runs adjacent to the northern edge of Highway 20. The Site is approximately 1.62 acres in size and is currently undeveloped land. The property is zoned as RR-5 (Rural Residential) (Figure 3). The property is registered as parcel number is 902-24-1020. County Assessor's parcel maps, Google Earth aerial maps, and ArcGIS Pro mapping software were used to determine locations and features of the Project Site (Figures 1-3). Initial field investigations of the wetlands were conducted by Mr. Graham Nott, with Mr. Trevor Shea on video conference, on May 4, 2021. A follow up investigation was conducted by Trevor Shea on June 21, 2021. This report was written by Trevor Shea, with assistance from Dr. G. Bradford Shea and Ms. Mary Ann Shea. The Project Site is currently an undeveloped, forested lot, with a cleared area in the center of the property. County and agency maps do not show any critical areas on-site, however a site visit conducted by Jefferson County found evidence of wetland vegetation. The proposed project is the construction of a single-family residence and septic system. The surrounding area consists of private residences and undeveloped lots. Mr. Kavon Novak with Sea-Kota Inc. contracted with Westech Company (Westech) to delineate the wetland that lies on the Project Site. The Project Site was found to contain a Category IV slope wetland (Wetland A) that flows across the middle of the property. Wetland Regulations have been enacted as part of the Jefferson County Critical Areas Protection Code (Sections 18.22.100-18.22.965). Methods of investigation are summarized in Chapter 2.0 of this report. Chapter 3.0 of this Report contains results of the delineation. Chapter 4.0 contains Conclusions and Recommendations, followed by Chapter 5.0, References. Appendix A contains Maps and Figures, Appendix B contains Site Photographs. Appendix C contains Wetland Data Forms, Appendix D contains the Rating Form and Maps, and Appendix E contains Weather Data. WW1684-FairmontHillRdWD.RPT/070821/tjs 2 2.0 METHODS The Wetland was delineated and rated according to procedures required by the Jefferson County Code (JCCAC) (Sections 18.22.100-18.22.965). The JCCAC requires that wetlands be identified and delineated (JCCAC 18.22.700) whenever wetlands are believed to occur within the property boundaries of the proposed development. The Project (single-family residence and septic system) is considered a “moderate intensity” land use under the County Code. Since the State of Washington now defers to the U.S. Army Corps of Engineers' (USACE or Corps) Wetland Delineation Methods, this wetland was delineated according to the Corps’ Wetland Manual (USACE 1987) and the Regional Supplement for the Western Mountains, Valleys and Coast Region (USACE 2010). The Wetland was rated by the methods outlined in the Washington State Department of Ecology's Wetland Rating System for Western Washington (DOE 2014). The following methods are drawn from the Corps’ Regional Supplement (USACE 2010). The Corps’ manual defines wetlands as those “areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances, do support, a prevalence of vegetation typically adapted for life in saturated soil conditions.” Wetlands are defined by the following three criteria: 1. Vegetation: Prevalent vegetation consisting of macrophytes (containing macro- phytic vegetation) adapted to areas with wetland hydrologic and soil conditions. 2. Hydric soils: Soils that are histosols, in aquic suborders or that show certain characteristics associated with poor draining, very poor draining or ponding for a long duration during the growing season. 3. Hydrology: Evidence that the area is inundated or saturated to the surface between 5 and 12.5 percent of the growing season in most years. Evidence of at least one (usually two or three) wetland indicators from each of these three categories is generally required to identify an area as a wetland. Preliminary data gathering consisted of the examining U.S. Geological Survey (USGS) maps, county parcel, wetlands, and topographic maps, aerial photographs, and Natural Resources Conservation Service (NRCS) soil surveys. Because these sources were insufficient to make a determination, additional information on site vegetation, soils and hydrology was gathered at the Site. The Site did not appear to have the complexity to require a comprehensive determination, therefore a Routine Determination with Onsite Inspection was used. WW1684-FairmontHillRdWD.RPT/070821/tjs 3 The Wetland and its boundary was initially estimated by noting likely areas of topographic and vegetative distinction between wetlands and uplands. The routine method for delineating wetlands begins with the identification of plant communities, as uplands and wetlands are often occupied by different assemblages of species determined by combinations of environmental influences. These plant communities were identified and evaluated for the presence or absence of hydrophytic vegetation. The wetland indicator status of the dominant species is used to determine the presence of hydrophytic vegetation. Each species has an indicator status defined according to the U.S. Department of Agriculture (USDA) (USDA 2012). A species indicator status refers to the relative frequency at which the species occurs in jurisdictional wetlands. Wetland plant species (OBL, FACW and/or FAC) must constitute greater than 50 percent of the dominant vegetation to meet Department of Ecology (DOE) criterion for hydrophytic vegetation (USACE 2010). Since non-dominant plants in the wetland was scattered irregularly throughout, small transects could not be utilized to estimate percent coverage. Accordingly, a combination of on-Site visual inspection and aerial maps were used to estimate percent coverage. These estimates were used to conduct a dominance test with 50/20 selection as described in the Corps manual (USACE 2010). Wetland plants were primarily identified in the field, with subsequent collection and keying when necessary. Plants were identified using the following sources: Hansen’s Northwest Plants Database 2021 USDA NRCS Plants Database 2021 Roche, Brainard & Wilson 2019 Guard 2010 Cooke 1997 Hitchcock and Cronquist 2018 Picture This – Plant Identifier 2021 Turner 2014 Taylor 1995 Keying of plants using magnifying lenses and dissecting microscope was used, as necessary. Determination of wetland indicator status utilized regional keys published by USDA. This indicator replaced the previous U.S. Fish and Wildlife key in June 2012 (USDA 2012). Areas with plant communities dominated by hydrophytic vegetation were then evaluated for wetland hydrology and hydric soils. Wetland hydrology refers to “all hydrological characteristics of areas that are periodically inundated or have soils saturated to the surface at some time during the growing season.” These are areas with evidence that the presence of water has an overriding influence on the characteristics of vegetation and soils due to anaerobic and reducing conditions (USACE 2010). WW1684-FairmontHillRdWD.RPT/070821/tjs 4 An area has wetland hydrology if it is inundated or saturated to the surface continuously for at least five percent (5%) of the growing season in most years. The level of inundation can range from permanently inundated to irregularly inundated/saturated. The level of inundation/saturation can be impacted by precipitation, topography, and soil characteristics. Hydrology is often the least exact of the parameters used to delineate wetland edges because it is the most ephemeral and leaves the least reliable traces in the landscape after water tables or floods have receded. Therefore, indicators of wetland hydrology are sometimes difficult to find in the field. However, it is essential that a wetland area is periodically inundated or has saturated soils for a sufficient duration during the growing season. Based on Corps regulations, Westech staff noted areas with evident characteristics of wetland hydrology. In general, places with wetland hydrology show evidence that the presence of water has had an overriding influence on characteristics of vegetation and soils due to anaerobic and chemically reducing conditions. Hydrologic conditions were determined through examination of topographic relief and drainage patterns. Soil moistness was determined by hand and, in the event of standing water, depth to standing water was noted. Field indicators of wetland hydrology include such features as watermarks, historic records, and visual observation of saturated soils or inundation. Evidence of hydric soils was checked along the apparent wetland boundary. These are soils that formed under conditions of saturation, flooding or ponding long enough during the growing season to develop anaerobic conditions in the upper layers. These soils are identified in the field mainly by morphological features such as color patterns, organic matter accumulation, and observation of inundation. Soils were sampled to depths of up to 18-24 inches using a wetland shovel and soil auger. Soil consistency was determined by feeling for grain size and texture. Soil moisture was determined at that time. In the event of saturated conditions in the hole, depth to standing water was noted. Soil color was determined through comparison of field samples with standard Munsell Color Charts (Munsell 2009). Soil was also examined for presence of redox features, gley or other indicators of anaerobic soil oxidation. If one or more of these indicators was present in the wetlands, the soil was considered hydric. The wetland was determined based on the Routine On-Site Field Method used by the Corps using a combination of vegetation, soil, and hydrology indicators. The boundary of the wetland was determined by first mapping each plant community area as wetland or non-wetland. The general wetland boundary was determined by the interface of these two mapping units. WW1684-FairmontHillRdWD.RPT/070821/tjs 5 Wetland boundaries were confirmed, and the boundary locations narrowed down by sampling specific transects along wetland boundaries. Various points were sampled for vegetation, soil, and hydrology in order to pinpoint the location of wetland boundaries. Appendix B contains the data form for one sample from a typical area of the delineated wetland. This test pit was paired with a test pit from an upland area in order to determine the wetland boundary in that area. Other pairs of test pits were also taken to help determine the boundary. The wetland boundary was indicated in the field by the use of pink flagging tape tied to 24” and 48” wooden stakes or tied to vegetation. Buffer widths were determined based the Jefferson County Code and mapped with GPS and ArcGIS Pro Software. The Wetland Field Data Station and associated soil test pits were indicated by blue and white diagonal flagging and stakes containing the test pit number (labeled VSH-# for vegetation, soils and hydrology stations). One site visit was carried out by Mr. Graham Nott on May 4th, 2021. Mr. Trevor Shea CWD was present by video call during this field visit as well. A follow up visit was conducted by Trevor Shea on June 21, 2021. This report was carried out jointly by Mr. Shea with assistance from Dr. G. Bradford Shea, and Ms. Mary Ann Shea (Administrator). Exploration of the Property (Site) involved noting Site characteristics such as hydrology and soil conditions. A botanical study involving identification of the plant species found growing on the Site was also conducted. The wetland edge was delineated, and photographic documentation was acquired (Appendix B). Measurements for mapping purposes were made using a fiberglass tape measure and handheld GPS units. WW1684-FairmontHillRdWD.RPT/070821/tjs 6 3.0 WETLAND DELINEATION RESULTS 3.1 Existing Conditions The Site lies along Highway 20 and Fairmont Hill Road, with Site access coming from Fairmont Hill Road. The Site is currently undeveloped and is mostly forested, with an open field area in the center of the property. Properties to the south, north and east are single family or undeveloped rural residential properties in unincorporated Jefferson County. The Site lies at an elevation between 120-160 feet above mean sea level (msl) and slopes downward from the top of the hill along Highway 20 along its southern boundary. Jefferson County maps do not show the on-site wetland, nor any other critical areas. Westech's field investigation found the on-site wetland to be a Category IV slope wetland that extends across the center of the site, flowing north from the base of the hill that abuts Highway 20 on the southern part of the property. The wetland area on the Property was mapped using GPS and mapped using ArcGIS software. This Wetland is classified as a palustrine forested slope wetland dominated by forested, shrub/scrub and herbaceous vegetation. Precipitation and Data Analysis Field investigations with data point collection were conducted on June 21st, 2021. Precipitation information was collected from the National Centers for Environmental Information (NCEI) and NRCS’s WETS station information. All data was taken from Chimacum WETS station (Station ID: 451414 (Coop)USC00451414 (GHCN)CHMW1 (NWS LI)). It had rained 1.00 inches in the 14 days prior to the first day of data point collection (June 21, 2021). The largest rain event occurred on June 14, 2021, with 0.21 inches of rainfall occurring. No rainfall occurred during field investigations (NCEI 2021, NRCS 2021). WETS percent averages were calculated based on data taken from 1971 to 2020 using NRCS AgASIS database. Based on NRCS WETS data, May saw 1.36 inches of rain which is above the 30th percentile of 1.34 inches but below the 70th percentile of 2.33 inches, and is therefore defined as “normal conditions”. April’s rainfall of 1.84 inches was also between the 30th (1.56 inches) and the 70th (2.59 inches) percentiles and therefore is also defined as “normal conditions”. In March, there was 1.65 inches of rain which is less than the 30th percentile average of 2.19 inches and is therefore also defined as “dry conditions”. The total score given to these three months collectively was 11, which is defined as “normal conditions” overall (score of 10-14 is classified as “normal”). WETS table and weather information is included in Appendix E. This data is presented in Table 1 below.

This forested section of the wetland gives way to a cleared area consisting of scattered herbaceous plants and bare ground. Wetland A vegetation is dominated by red alder (Alnus rubra) (FAC) in the canopy layer, Salmonberry (Rubus spectabilis) (FAC) in the shrub layer, and creeping buttercurp (Ranunculus repens) (FAC) and fowl mannagrass (Glyceria striata) (OBL) in the herbaceous layer. The upland area is dominated by Douglas fir (Pseudotsuga menziesii) (FACU), Western red cedar (Thuja plicata) (FAC) and big leaf maple (Acer macrophyllum) (FACU) in the canopy layer, trailing blackberry (Rubus ursinus) (FACU), and sword fern (Polystichum munitum) (FACU) in the shrub layer, and common nipplewort (Lapsana communis) (FACU), and salal (Gaultheria shallon) (FACU) in the herbaceous layer.

WW1684-FairmontHillRdWD.RPT/070821/tjs 9 Soils “Hydric soils” is a name for soils commonly found in wetlands. These soils are identified mainly by morphological features such as color patterns, organic matter accumulation, or observation of inundation. A soil may be considered hydric if it is inundated (flooded or ponded) for at least one continuous week during the growing season in most years (Corps 2010). Westech staff looked for field indicators of hydric soil conditions as recommended by the Corps. If one or more of these indicators was present in the wetlands, the soil was considered hydric (Corps 2010). Westech staff examined existing NRCS soil surveys of the Site. The NRCS mapped two dominant soils on the Site (NRCS 2021) which is shown in Figure 4. The specific soils at the Site are: Agnew silt loam (AgE), 30-50 percent slopes: This soil is somewhat poorly drained with a depth to the restrictive feature of more than 80 inches below the surface. Its parent material consists of glaciomarine deposits and primarily forms on escarpments. This soil’s capacity to transmit water is classified as moderately low to very high (0.06 to 0.20 inch/hour) and has a depth to water table approximately 12 to 24 inches. Available water capacity is high (about 11.5 inches) and it has no frequency of ponding or flooding. This soil type is not classified as “Hydric”. Clallam gravelly sandy loam (CmD), 15 to 30 percent slopes: This soil’s is a well-drained soil and has a depth to the restrictive layer between 20 to 40 inches below the surface. Its parent material consists of basil till and has a depth to water table between about 19 to 39 inches. This soil’s capacity to transmit water is classified as very low to moderately low (0.00 to 0.06 inch/hour) and has no frequency of ponding or flooding. This soils type is not classified as “Hydric”. Because NRCS soil surveys do not necessarily capture small scale variation, Westech staff conducted additional field studies of the soils. To examine soils in the wetland boundary, Westech staff dug soil pits and observed soil characteristics. The location of two of these plots has been marked in the field using wooden stakes tied with blue and white striped flagging. The soil information taken at these sample points is highlighted in Table 3 and shown in Appendix C. Wetland soils were found to be mostly clay and loamy clay soils. These soils are not consistent with either Clallam gravelly sandy loam or Agnew silt loam soils and appear to have been formed due to the consistent water flow down the hillslope. The uplands were found to be more consistent with the characteristics of both soil types. Overall, surface soils on the Site appear to be roughly consistent with the NRCS mapping. WW1684-FairmontHillRdWD.RPT/070821/tjs 10 Field investigations found that the soils conformed roughly to the NRCS characterization, in the upland areas consisting of gravelly loams in the upland. Clay and loamy clay soils were found in the wetland based on data from the test quadrats (soils test pits and surrounding vegetation). The Wetland soil pits showed soils with a dark value/chroma (3/2 or darker) with a reduced matrix (VSH-1). No restrictive layers were found within those depths. These soils meet the U.S. Army Corps criterion for hydric soils described as Depleted Matrix (F3). The soil pits taken in the upland area consisted of gravelly sand had a chroma/value of 5/2 (10YR) with a gravel layer at 18 inches. These soils did not meet Army Corps hydric soils criterion.

Hydrology for Wetland A is sustained from upslope runoff and direct precipitation. The interior of the wetland appears to be seasonally inundated as standing water was observed during initial field investigations (May) but was not observed during the follow up investigations (June). Field investigations were taken during the end of the growing season (June). During these investigations, the wetland soils were saturated but did not have any inundation or high-water table. Hydrological indicators observed consisted of Saturation (A3). 3.2 Description of Critical Areas Westech’s field investigations determined that one Category IV slope wetland is located on the property. Two soil test pits were taken, and the wetland boundary was mapped using GPS measuring software. Figure 5 shows the wetland shape and test pit locations. Wetland A is a slope wetland classified as palustrine forested. The wetland begins at the base of the steep hill along the southern boundary of the property and flows north before disappearing underground. This wetland is approximately 2,200 square feet (0.05 acres) in size and crosses the middle of the property. The wetland appears to have been created from rainfall and subsurface flow from the hillside above that collected at the base before continuing down the slope. Wetland boundaries were determined by first noting likely areas of topographic and vegetative distinction between wetland and uplands. The Site vegetation was found to transition from upland to wetland in a relatively abrupt fashion, apparently due to topography. Evidence of hydric soils was checked along the apparent wetland boundary. Westech staff noted the presence of soils marked by redox features in the boundary areas of each wetland. Westech staff also noted the presence of hydrological indicators. While difficult to find, and often the least exact of the three indicators, Westech staff noted areas with evident characteristics of wetland hydrology, places where the presence of water has an overriding influence on characteristics of vegetation and soils due to anaerobic and chemically reducing conditions. These indicators are listed above and can also be found in Appendix C. The vegetation, soils, and hydrology of the Site are described in more detail in the previous subsections. Results of these three factors at two test pits (one in the wetland, one in the upland areas) are contained in Appendix C. Figure 5 shows the location of the wetland relative to nearby features. Site photographs are shown in Appendix B. WW1684-FairmontHillRdWD.RPT/070821/tjs 12 3.3 Land Uses and Habitat Values Wetlands are transitional areas between upland and aquatic environments where water is present long enough to form distinct soils, and where specialized, water-tolerant plants grow. Wetlands serve a variety of functions such as transferring surface water into the ground, thereby recharging groundwater supplies. Wetlands trap water along with sediments and pollutants providing storm-water detention and filtration; mitigate flood impacts; and provide wildlife habitat. Wetland buffers are important because they reduce the adverse impacts of adjacent land uses on wetlands. The buffers serve to stabilize soil and prevent erosion, filter suspended solids, nutrients and toxic substances and moderate impacts of storm-water runoff. As such, buffers serve to preserve wetland functions. They also provide important habitat for wildlife living in and around the wetland. The Site was checked using the Washington Department of Fish and Wildlife “Priority Habitats and Species” database. This showed no habitat features located on-site and no threatened or endangered species within 1.0 miles of the site. The Property is currently zoned RR-5 (Rural Residential) and is surrounded by a mixture of undeveloped lots and individual single-family residences. The proposed project (single-family residence) is considered as moderate intensity land use. 3.4 Wetland Types and Buffers The buffer sizes to be applied at this Site are governed by the Jefferson County Critical Areas Code. In order to establish buffer sizes, Jefferson County requires that wetlands be rated using the Washington State Department of Ecology's Wetland Rating System for Western Washington (WDOE 2006, 2014). In this system, wetland ratings are based on: 1) Water Quality Function (i.e., Does the wetland have the ability to improve water quality?) 2) Hydrologic Function (i.e., Does the wetland decrease flooding and/or erosion?) 3) Habitat Function (i.e., Does the wetland provide habitat for many species?) In Washington, wetland rating categories are based on the rarity of the type of wetland, our ability to replace it, its sensitivity to adjacent human disturbances, and the functions it performs. The objective of the rating system is to divide wetlands into groups that have similar needs for protection. WW1684-FairmontHillRdWD.RPT/070821/tjs 13 Wetland A was rated as a Category IV slope wetland with an overall score of 14 (DOE 2014). This wetland had a Water Quality score of 5, Hydrologic score of 4 and a Habitat score of 5. Under Jefferson County’s Code, a project of this type is considered “moderate intensity”. A Category IV wetland buffer for a moderate intensity project is typically 40 feet. However, there is a size threshold exemption in Jefferson County for wetlands less than 0.10 acres in size. As this wetland is only approximately 0.05 acres in size, it is below this threshold and is therefore exempted from any buffer regulations. Figure 5 shows Wetland A’s boundary. 3.5 Jefferson County Wetland Maps Jefferson County does not have any wetlands mapped on the Site on its Critical Areas website. No other critical areas are mapped on-site. WW1684-FairmontHillRdWD.RPT/070821/tjs 14 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 Conclusions The proposed project is the construction of a single-family residence and drain-field. Access to the Site is provided by a private driveway that extends from Fairmont Hill Road to the west of the Site. The Site is currently undeveloped. Wetland characteristics were observed by County personnel during the permitting process which triggered the need for this delineation report. Most of Wetland A is dominated by forested vegetation and is located in the center of the property. The Wetland was classified as a Category IV slope wetland with a habitat score of 5, normally requiring a 40-foot buffer under the Jefferson County Code (Chapter 18.22.700) for moderate-intensity projects like this one. However, Wetland A is approximately 0.05 acres in size, which is below the 0.10-acre size threshold exemption in the Jefferson County Code. The size of Wetland A therefore exempts it from typical buffer regulations. The wetland boundary is shown on Figure 5. 4.2 Recommendations Although Wetland A is not subject to typical County buffer regulations due to being less than 0.10 acres in size, any construction activities on the Site should be conducted outside of the delineated wetland boundary. A construction fence (silt fence or equivalent erosion control measure) should be placed between the construction area and the wetland boundary prior to any disturbance for the project. Placement of the fences should be based on locations of critical areas as delineated and described in this report and as staked by Westech Company in the field. Disturbance activities should not take place after September 30 or before May 1 without all possible erosion control measures in place.

NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. 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 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 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% of the open water area is deeper than 6.6 ft (2 m). NO – 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 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. NO – go to 5 YES – The wetland class is 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. For questions 1-7, the criteria described must apply to the entire unit being rated. 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. A Wetland name or number ______ Wetland Rating System for Western WA: 2014 Update 4 Rating Form – Effective January 1, 2015 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 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during 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 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. 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. HGM classes within the wetland unit being rated HGM class to use in rating 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 + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Add the number of structures checked. ____Aquatic bed 4 structures or more: points = 4 ____Emergent 3 structures: points = 2 ____Scrub-shrub (areas where shrubs have > 30% cover) 2 structures: points = 1 ____Forested (areas where trees have > 30% cover) 1 structure: points = 0 If the unit has a Forested class, check if: ____The Forested class has 3 out of 5 strata (canopy, sub-canopy, shrubs, herbaceous, moss/ground-cover) that each cover 20% within the Forested polygon H 1.2. Hydroperiods Check the types of water regimes (hydroperiods) present within the wetland. The water regime has to cover more than 10% of the wetland or ¼ ac to count (see text for descriptions of hydroperiods). ____Permanently flooded or inundated 4 or more types present: points = 3 ____Seasonally flooded or inundated 3 types present: points = 2 ____Occasionally flooded or inundated 2 types present: points = 1 ____Saturated only 1 type present: points = 0 ____Permanently flowing stream or river in, or adjacent to, the wetland ____Seasonally flowing stream in, or adjacent to, the wetland ____Lake Fringe wetland 2 points ____Freshwater tidal wetland 2 points H 1.3. Richness of plant species Count the number of plant species in the wetland that cover at least 10 ft2. Different patches of the same species can be combined to meet the size threshold and you do not have to name the species. Do not include Eurasian milfoil, reed canarygrass, purple loosestrife, Canadian thistle If you counted: > 19 species points = 2 5 - 19 species points = 1 < 5 species points = 0 H 1.4. Interspersion of habitats Decide from the diagrams below whether interspersion among Cowardin plants classes (described in H 1.1), or the classes and unvegetated areas (can include open water or mudflats) is high, moderate, low, or none. If you have four or more plant classes or three classes and open water, the rating is always high. None = 0 points Low = 1 point Moderate = 2 points All three diagrams in this row are HIGH = 3points A X 1 X X 1 1 1 X Wetland name or number ______ Wetland Rating System for Western WA: 2014 Update 14 Rating Form – Effective January 1, 2015 H 1.5. Special habitat features: Check the habitat features that are present in the wetland. The number of checks is the number of points. ____Large, downed, woody debris within the wetland (> 4 in diameter and 6 ft long). ____Standing snags (dbh > 4 in) within the wetland ____Undercut banks are present for at least 6.6 ft (2 m) and/or overhanging plants extends at least 3.3 ft (1 m) over a stream (or ditch) in, or contiguous with the wetland, for at least 33 ft (10 m) ____Stable steep banks of fine material that might be used by beaver or muskrat for denning (> 30 degree slope) OR signs of recent beaver activity are present (cut shrubs or trees that have not yet weathered where wood is exposed) ____At least ¼ ac of thin-stemmed persistent plants or woody branches are present in areas that are permanently or seasonally inundated (structures for egg-laying by amphibians) ____Invasive plants cover less than 25% of the wetland area in every stratum of plants (see H 1.1 for list of strata) Total for H 1 Add the points in the boxes above Rating of Site Potential If score is: 15-18 = H 7-14 = M 0-6 = L Record the rating on the first page H 2.0.
