Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park Wetland and Stream Delineation Report Submitted to: Jefferson County Public Works 623 Sheridan Street Port Townsend, WA 98368 October 9, 2023 Prepared by: Otak, Inc. 2828 Colby Avenue, Suite 401 Everett, WA 98201 Otak Project No. 33425 Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park i Wetland and Stream Delineation Report Otak Executive Summary Jefferson County Public Works is planning to construct a segment of the Olympic Discovery Trail Project approximately three miles in length from the south end of the Larry Scott Trail at Milo Curry Road running east and south to Anderson Lake State Park in Jefferson County. The trail will include clearing, grading, and fill during construction. The project aims to accommodate pedestrians, runners, bicyclists, equestrians, and other non- motorized/recreational trail users. Otak, Inc. (Otak) was hired by Jefferson County to complete a wetland and stream delineation report to document baseline conditions and support project design and environmental permit applications. This report was completed by reviewing background information, delineating wetland and stream boundaries in the field, classifying wetlands and stream habitats, and determining buffer widths per Jefferson County Code (JCC) Chapter 18.22 (Critical Areas). Critical areas reviewed for this report include wetlands and fish and wildlife habitat conservation areas (FWHCAs). Biologists from Otak conducted the field investigation on March 2 through March 4, 2022, and an additional field assessment on May 10, 2023, for additional easement area that was acquired after March 2023. The study area for this report includes the right of way and easement boundary along South Discovery Road and 4 Corners Road, the entire width of the utility easement trail section south of 4 Corners Road, and the trail easement corridor from the utility easement to Anderson Lake State Park. Areas outside of the right of way and easements were visually assessed to identify wetlands or streams with buffers that could extend back into the study area. Wetland and stream boundaries were delineated in the field with pink and orange flagging for wetlands and streams, respectively. Habitat assessments for sensitive fish, wildlife, and plant species were completed in the field. Suitable habitat for sensitive fish, wildlife, and plant species was not observed during the field investigation due to previous site disturbances from development, logging, forest management, and maintenance of the utility corridor. Twenty-one wetlands and three watercourses were identified in the study area. Wetland habitats consist of palustrine forested, scrub-shrub, and emergent Cowardin classes. Wetlands have riverine, depressional, and slope hydrogeomorphic classes. Wetland buffer widths range from 40 to 225 feet per JCC 18.22.730 (Standard Wetland Buffer Widths). Wetlands were rated using the Washington State Wetland Rating System for Western Washington – 2014 Update (Hruby 2014) per JCC 18.22.710 (Classification/designation). Watercourses within the study area include three non-fish, seasonal streams with 50-foot buffer widths.

Introduction Otak, Inc. (Otak) was hired by Jefferson County Public Works (County) to complete a Wetland and Stream Delineation Report to document baseline environmental conditions within the study area for the proposed Olympic Discovery Trail extension project. Information this report will be used to support permitting with local, state, and federal resource agencies. Critical areas and habitats covered in this report include wetlands and fish and wildlife habitat conservation areas (FWHCAs). The project is an approximately three mile long pedestrian trail from the south end of the Larry Scott Trail at Milo Curry Road running east and south to Anderson Lake State Park in Jefferson County This report was completed by reviewing background information and completing field work in March 2022 and May 2023 to delineate wetlands and streams within the acquired easements and existing right of way (ROW) for the project. The potential presence of suitable habitat for sensitive wildlife species and species of local importance was also assessed. This report documents wetland and stream boundaries and classifications, associated buffer widths, and existing wildlife habitat in the study area. 1.1 Project Location and Landscape Setting The project is generally located within an approximately three mile long existing road and utility corridor and previously logged forest lands. Adjacent land use along South Discovery Road at the north end of the project includes a United Postal Service Pickup facility, an auto wrecking yard, a storage facility, a gas station, and the Jefferson Transit Park and Ride. Land use outside of the utility corridor is mixed rural residential and logging, in unincorporated Jefferson County, Washington (Appendix B: Figure 1–Vicinity Map). The project corridor is located within easements along South Discovery Road and Four Corners Road. Anderson Lake State Park abuts the southeast terminus of the study area where the trail is expected to continue on to State Park property in the future. The project is located in Sections 4 and 9, of Township 29 North, Range 01 West, and Sections 32, and 33 of Township 30 North, Range 01 West, located entirely in Water Resource Inventory Areas (WRIA) 17 – Quilcene – Snow watershed. 1.2 Project Description This project aims to construct a segment of the Olympic Discovery Trail Project approximately three miles in length located from the south end of the Larry Scott Trail at Milo Curry Road running east and south to Anderson Lake State Park in Jefferson County. The trail will be part of a coordinated regional system that will eventually connect the Larry Scott Trail to Discovery Bay as part of the Eaglemount segment of the Olympic Discovery Trail. By constructing the trail segment, pedestrians, runners, bicyclists, equestrians, and other trail users with non- motorized equipment will have an alternative to Highway 20 for travel between the existing trail segments. This project will subsequently increase community use of the existing trail systems by increasing the accessibility of the north and south trails and lowering the overall risk to non-motorized traffic along Highway 20. 1.3 Study Area The study area for this report included areas of potential ground disturbance plus 300 feet in accordance with JCC 18.22.960(3) (Wetland reports) (Appendix B: Figure 2–Study Area Map). The study area includes the right of way and easement boundary along South Discovery Road and 4 Corners Road, the entire width of the utility easement trail section south of 4 Corners Road, and the trail easement corridor from the utility easement to Anderson Lake State Park. Areas outside of the right of way and easements were visually assessed to identify wetlands or streams with buffers that could extend back into the study area. Wetland and stream boundaries were delineated in the field with pink and orange flagging for wetlands and streams, respectively. Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 2 Wetland and Stream Delineation Report Otak Chapter 2. Methods This chapter summarizes the methods used in accordance with local, state, and federal guidance in delineating wetland and stream boundaries in Washington State. See Table A-1 in Appendix A for further details regarding the methods used to produce this report. 2.1 Review of Available Published Information Available published information was reviewed prior to the field investigation to identify any previously documented wetlands, streams, habitat areas, or other pertinent site characteristics (e.g., vegetation community patterns, topography, soils, or water courses) that would indicate the presence of wetlands and streams within the project site. These maps are typically used as guidance, and do not supersede conditions in the field. As part of this effort Otak biologists reviewed the following sources: ▪ Soil survey from the United States Natural Resources Conservation Service (NRCS) (NRCS 2022); ▪ National Wetlands Inventory (NWI) map (USFWS 2022); ▪ Washington Department of Natural Resources (WDNR) Forest Practices Application Mapping Tool (WDNR 2022); ▪ Washington State Department of Fish and Wildlife (WDFW) Priority Habitat and Species (PHS) maps (WDFW 2022) and Statewide Washington Integrated Fish Distribution (SWIFD) (WDFW 2022a); and ▪ Jefferson County Public Lands Records (Jefferson County 2022). Appendix B contains figures associated with the background review, including: an aerial photograph of the study area (Figure 2), NWI map (Figure 3), NRCS Soils Map (Figure 4), WDNR Stream Typing Map (Figure 5), and Jefferson County Public Land Records Map depicting wetlands, streams, and fish passage barriers (Figure 6). Soil units mapped within the study area are listed in Table 2-1. Agnew silt loam, Alderwood gravelly sandy loam, Cassolary sandy loam, Dick loamy sand, Hoypus gravelly sandy loam, Swantown gravelly sandy loam, Tukey gravelly loam. No soils within the study area are classified as hydric soils. Table 2-1. NRCS Soil Units Mapped in the Study Area Mapped Soil Unit Slope % Drainage Class Landform Parent Material Hydric? Agnew silt loam (AgB) 0-8 Somewhat poorly drained Terraces Glaciomarine deposits No Alderwood gravelly sandy loam (AlC) 0-15 Moderately well drained Terraces Basal till with a component of volcanic ash in upper part No Cassolary sandy loam (CfC) 0-15 Well drained Terraces Glacial drift and/or marine deposits No Dick loamy sand (DcC) 0-15 Somewhat excessively drained Plains, terraces Glacial outwash No Hoypus gravelly sandy loam (HvC) 0-15 Somewhat excessively drained Terraces Glacial outwash No Swantown gravelly sandy loam (SuB) 0-8 Poorly drained N/A Till No Tukey gravelly loam (TuC) 0-15 Moderately well drained Terraces Basal till No Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 3 Wetland and Stream Delineation Report Otak The NWI mapper identifies four riverine wetland habitats within the study area. All four NWI-mapped wetlands are identified as classification code R4SBC [Riverine (R), Intermittent (4), Streambed (SB), and the water regime as Seasonally Flooded (C)]. Jefferson County Public Lands records shows the NWI-mapped wetlands within the study area as Washington Department of Natural Resources (DNR) streams, and type the streams using the former DNR water typing system. Three of the mapped streams are Type 5 (Non-Fish Seasonal) and one is Type 9 (unknown/untyped mapped stream). No additional fish and wildlife habitat areas or wetlands are mapped within the study area. The WDNR Forest Practices Application Mapping Tool maps three streams within the study area. All streams are Type N (nonfish habitat), formerly Type 5 streams, without an associated description of seasonal or intermittent flow. Type 9 streams are classified as unknown/untyped. WDFW’s PHS on the Web does not identify any priority habitats and species in the project vicinity. The SWIFD mapper identifies four National Hydrology Dataset (NHD) flowlines in the study area. No fish species or habitat have been documented in the streams within the study area. The U.S. Fish & Wildlife Service (USFWS) Information for Planning and Consultation (IPaC) tool lists the potential presence of species listed as Threatened (T), Endangered (E), Candidate (C), and Proposed Similarity of Appearance to a Threatened Taxon (PSAT) under the Endangered Species Act (ESA) in the study area. Three bird species are listed within the study area, including Marbled Murrelet (Brachyramphus marmoratus) (T), Streaked Horned Lark (Eremophila alpestris strigata) (T), and Yellow-Billed Cuckoo (Coccyzus americanus) (T). ESA-listed fish species potentially present include Bull Trout (Salvelinus confluentus) (T) and Dolly Varden (Salvelinus malma) (PSAT). ESA-listed insects potentially present within the study area include Monarch Butterfly (Danaus plexippus) (C) and Talor’s Checkersport (Euphydryas Editha taylor) (E). Golden Paintbrush (Castilleja levisecta) (T), a flowering plant, is also listed. The IPaC tool does not map any critical habitats within the study area. Suitable habitat for these species was not observed during the field investigation as discussed in Section 3 of this report. 2.2 Precipitation Data and Analysis 2.2.1 Evaluation of the Growing Season Wetland hydrologic conditions are considered present if soils are inundated or saturated to the surface continuously for at least 5 percent of the growing season in most years (50 percent probability of recurrence) (USACE 1987). The technical standard for disturbed or problematic sites requires 14 or more consecutive days of flooding or ponding, or a water table 12 inches or less below the soil surface, during the growing season, at a minimum frequency of 5 years in 10 (USACE 2010). The beginning and ending dates of the growing season can be defined based on two indicators of biological activity that are readily observable in the field: (1) above ground growth and development of vascular plants, and (2) soil temperature. However, due to seasonal fluctuations from year to year the growing season dates may also be approximated by the number of frost-free days, defined as the time from the last date in spring when the ambient air temperature drops to 28°F, to the first date in fall when it drops to 28°F, over a 30-year period (USACE 2010). As such, the beginning and ending dates for the growing season for the project site were estimated from long- term weather records (1993-2022) as the median dates (50 percent probability) for the first and last 28°F days at the Sequim 2 E Climate Station. Based on long-term weather records the average start and end dates for the growing season for the area are April 2, and November 5, respectively, for a total growing season of 217 days (NRCS 2023a). Continuing wetland hydrologic conditions must be present for at least 11 consecutive days during the growing season for this site. Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 4 Wetland and Stream Delineation Report Otak 2.2.2 Precipitation Data during Field Investigation The initial field survey for the project was conducted on March 2 - March 4, 2022 and an additional field visit was completed May 10, 2023 to assess newly acquired easement area. The area received 1.43 inches of precipitation in the two-week period (February 15 – March 1, 2021) prior to the initial field survey, and 0.82 inches from April 26 – May 9, 2023) as measured at the Sequim 2 E Climate Station (NRCS 2023a). Precipitation amounts for the three months preceding the initial field survey were above normal in December 2021, below normal in January 2022, and normal in February 2022 (Table 2-2). A precipitation summary for the months preceding the 2023 field visit is included in Table 2-3. Precipitation amounts were normal in February 2023, normal in March 2023, and below normal in April 2023. Table 2-2.

An additional survey was conducted by Otak biologists on May 10, 2023, to review newly acquired easement areas. Wetlands and streams were delineated within the easements and right of way where access was granted, and areas outside of easements and right of way were visually assessed using field indicators such as changes in vegetation communities. 2.3.1 Wetlands In accordance with federal, state, and local guidance and regulations, Otak biologists delineated wetlands within the study area using the three-parameter approach detailed in the Corps of Engineers Wetlands Delineation Manual (USACE 1987), and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) (USACE 2010). Following routine methodology, data on vegetation, soils, and hydrology were collected at paired (wetland/upland) data points for wetlands that could be accessed within the easements associated with the project. The USACE wetland determination data forms for the data points are provided in Appendix C. Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 5 Wetland and Stream Delineation Report Otak Vegetation Representative upland and wetland vegetation communities were documented at each data point during the field survey. Typically, three vegetation strata are inventoried at each data point, including trees within a 30-foot diameter plot, shrubs within a 15-foot diameter plot, and non-woody herbaceous plants (including forbs, grasses, sedges, and rushes) within a 5-foot diameter plot. Plant species in each stratum were identified and absolute percent cover was recorded. Each species was listed following the scientific nomenclature given in the United States Department of Agriculture (USDA) PLANTS database (NRCS 2022b). The wetland indicator status for each species was assigned using the 2020 National Wetland Plant List for the Western Mountains, Valleys & Coast Region (USACE 2020). The dominance test was the primary indicator used to determine the presence or absence of hydrophytic vegetation. A data point is considered to have a hydrophytic vegetation community if more than 50 percent of the dominant species have an indicator status of facultative (FAC), facultative-wetland (FACW), or obligate (OBL). Dominant species are defined as those that individually or collectively account for more than 50 percent of the total areal coverage of vegetation in the stratum, plus any other species that, by itself, accounts for at least 20 percent of the total areal coverage (USACE 2010). If more than 50 percent of the dominant plant species in a community have wetland indictor status of OBL, FACW, or FAC, then the plant community is considered hydrophytic (wetland). Soils Per U.S. Army Corps of Engineers (USACE) protocol, soil samples were obtained at representative data points by digging a pit to a depth of at least 18 inches if possible to determine the presence or absence of hydric soil indicators using the Field Indicators of Hydric Soils in the United States, Version 8.2 (NRCS 2018). Soil colors were evaluated against a Munsell® soil color chart (Gretag/Macbeth 2000) to distinguish hydric from non-hydric soils. Hydric soils are defined as soils that are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part of the soil profile (USACE 2010). Hydric soils may exhibit certain characteristics that can be observed in the field; such as: high organic content, accumulation of sulfidic material, greenish or bluish-gray color (gley formation), depleted matrices, and development of redoximorphic features. Hydrology Wetland hydrologic conditions are considered present if, during the growing season, an area has 14 or more consecutive days of flooding or ponding; or a water table 12 inches or less below the soil surface, during the growing season at a minimum frequency of 5 years in 10 (USACE 1987 and 2010). The presence of primary and secondary wetland hydrologic indicators was determined at each wetland data point. Primary indicators of wetland hydrology may include, but are not limited to, surface water, soil saturation within 12 inches of the surface, shallow water table, and evidence of previous water inundation or saturation (e.g., watermarks, algal mats, sediment deposits). Secondary indicators may include wetland drainage patterns, geomorphic position, stunted or stressed plants, and water-stained leaves. When at least one primary or two secondary indicators were observed, wetland hydrology was determined to occur during the growing season long enough to result in wetland hydrology conditions. 2.3.2 Ordinary High Water Mark The ordinary high water mark (OHWM) along streams within the study area were determined in the field based on the methodology outlined in USACE Regulatory Guidance Letter 05-05 (USACE 2005) and Determining the Ordinary High Water Mark for Shoreline Management Act Compliance in Washington State (Ecology 2016). Identification of OHWM was based on the evaluation of stream physical characteristics, such as: presence of bed and banks, a natural line impressed on the bank, change in sediment and vegetation characteristics, wracking, erosion/scour, and silt deposits. Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 6 Wetland and Stream Delineation Report Otak 2.3.3 Fish and Wildlife Habitat Conservation Areas Fish and Wildlife Habitat Conservation Areas (FWHCAs) include those areas that serve a critical role in sustaining needed habitat and species for the functional integrity of the ecosystem. FWHCAs are identified as being of critical importance to the maintenance of endangered, threatened, or sensitive species of fish, wildlife or plants, or designated habitats and species of local importance per JCC 18.22.600-660 (Article VI. Fish and Wildlife Habitat Conservation Areas), including rivers, streams, shellfish areas, kelp and eelgrass beds, forage fish spawning areas, naturally occurring ponds less than 20 acres, aquatic resources planted wit game fish, natural preserves, and state wildlife areas. Habitats within the study area and the surrounding vicinities were assessed in the field by Otak biologists to determine potential suitability for sensitive fish, wildlife and plant species. The USFWS IPaC mapping tool was queried for the potential presence of federally-listed ESA species as provided in Section 2.1 of this report. WDFW’s PHS on the Web does not identify any priority habitats or species with the project vicinity. Suitable habitat for sensitive fish, wildlife, and plant species was not observed during the field investigation as discussed in Section 3 of this report. Rivers and streams are also designated as FWHCAs (JCC 18.22.610). Rivers and streams are assigned prescriptive FWHCA Buffers per Table 18.22.630(1) (Stream Buffers). Four streams are mapped within the study area by WDNR FPMAT, NHD, and Jefferson County Public Land Resources map applications (Section 2.1 f this report). Results of the field delineation and habitat assessment are provided in Section 3.3 (Existing Conditions). 2.4 Wetland and Stream Classification and Ratings Wetlands in the study area were classified according to Classification of Wetlands and Deepwater Habitats of United States (Cowardin, et al. 1979), and the hydrogeomorphic (HGM) wetland classification system as adopted by Hruby (2014). Wetland functions were rated using the Washington State Wetland Rating System for Western Washington – 2014 Update (Hruby 2014) per JCC 18.22.710 (Classification/designation). Wetland standard buffer widths were determined based on wetland category/characteristics, habitat score, and a moderate level of land use intensity per JCC 18.22.730(6)(d)(i) (Protection Standards). Wetland buffer conditions were qualitatively assessed based on vegetation cover, land use, and presence of invasive species. Wetlands and streams that were identified outside of the easements were rated to determine if buffer widths could potentially extend into project impact areas. Stream classification and buffer widths were determined according to JCC 18.22.630 (Protection Standards). 2.5 Mapping Methods Wetlands and streams (OHWM) boundary flags were professionally surveyed after the field delineation was completed. Any additional potential stream and wetland areas within 300 feet of study area was estimated using aerial photography, lidar imagery, and observations made during the field investigation. Survey data was transferred to Geographic Information Systems software, ArcGIS Pro version 2.8.7, to prepare exhibits for this report (Appendix B: Figure Set 7). Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 7 Wetland and Stream Delineation Report Otak Chapter 3. Existing Conditions Otak biologists identified twenty-one wetlands and three watercourses in the study area as shown in Figure Set 7 in Appendix B. Wetland classes, ratings, sizes, and buffer widths are summarized in Table 3-1, and stream characteristics are summarized in Table 3-2. Species and wildlife habitat conservation areas are addressed in Section 3.3. Wetland determination data forms are provided in Appendix C, and Washington State Department of Ecology (Ecology) wetland rating forms are provided in Appendix D. Site photographs are provided in Appendix E. 3.1 Wetlands Wetland 1. Wetland 1 is located northwest of Anderson Lake State Park and is partially within the trail easement. The majority of Wetland 1 is located north of the trail easement. The area, including Wetland 1, was last logged in 2016. The wetland has a depressional HGM class with palustrine scrub-shrub (PSS) and forested (PFO) Cowardin habitat classes. Dominant plant species within the wetland are salmonberry (Rubus spectabilis), red alder (Alnus rubra), and common rush (Juncus effusus). The wetland is bordered by uplands with a similar plant community with the addition of western swordfern (Polystichum munitum) and salal (Gaultheria shallon). The wetland boundary was determined by the lack of hydric soil and wetland hydrology indicators in the uplands. Photographs 1 and 2 in Appendix E show the typical habitat conditions within the wetland unit. Wetland 2. Wetland 2 is located east of Wetland 1 and extends south into Anderson Lake State Park. The wetland has a depressional HGM class with a PFO Cowardin class. The wetland is dominated by an overstory of red alder, a scrub-shrub community of salmonberry, and an understory of slough sedge (Carex obnupta), lady fern (Athyrium cyclosorum), and common rush. Uplands adjacent to the wetland unit include Douglas-fir (Pseudotsuga menziesii), western redcedar (Thuja plicata), salmonberry, and western swordfern. Photographs 3 and 4 show habitat conditions within the wetland unit. Wetland 3. Wetland 3 is a small (<0.01 acre) depressional wetland located approximately 15-feet north of Wetland 2 and 15-feet south of Wetland 4. The Cowardin class present within the wetland unit is PSS, with dominant vegetation including salmonberry and common rush. Ponded water was present within the unit. Woody debris piles are present from previous logging in and near the wetland. Upland vegetation bordering the unit includes salmonberry and western swordfern. Photographs 5 through 7 show the upland buffer conditions and wetland habitat conditions for Wetland 3. Wetland 4. Wetland 4 is located north and east of Wetland 3 and extends north and east outside of the trail easement. The depressional wetland is dominated by palustrine emergent (PEM), PSS, and PFO Cowardin habitat classes. An overstory of red alder occupies the tree stratum, areas of salmonberry dominate the scrub stratum, and open areas of water parsley (Oenanthe sarmentosa) form the herb stratum. Flowing water is present within the wetland unit running from west to east. The wetland extends east, outside of the study area and appears to have a hydrologic surface connection with Anderson Lake based on lidar imagery. Photographs 8 through 11 show habitat conditions within Wetland 4, and upland conditions outside of the wetland within Anderson Lake State Park. Wetland 5. Wetland 5 is located outside of the trail easement and within the north-south aligned utility corridor near the southern extent of the study area. The boundaries of Wetland 5 were estimated based on clear topographic changes, hydrophytic vegetation, and surface ponding to determine the buffer area that extends into the trail easement. The unit is in an isolated depression perched on a hillslope, bordered by the maintenance road (moderate intensity land use) to the west and relatively undisturbed forest land (low intensity land use) to the east. Wetland 5 is a depressional wetland with a PSS Cowardin habitat class with areas of seasonal ponding. The PSS plant community is dominated by Douglas spirea (Spiraea douglasii). Photograph 14 shows typical vegetation and standing water observed within Wetland 5.

Wetlands shown in Figure Set 7 in Appendix B. 2. Cowardin et al. (1979). Class based on vegetation: PFO = Palustrine Forested, PSS = Palustrine Scrub Shrub, PEM = Palustrine Emergent. 3. Wetlands rated according to Hruby 2014 per JCC 18.22.710 (Classification/designation). 4. Wetland sizes are approximate for wetland extending past the easements based on delineated wetland edges, lidar imagery, NWI mapping, and current aerial imagery. 5. Proposed land adjacent land use and are categorized and designated per JCC 18.22.730(6). 6. Wetland standard buffer width per JCC 18.22.730 is based on a combination of wetland category, habitat function score (from the wetland rating form), and land use intensity. Wetland 6. Wetland 6 is located north of Wetland 5 partially within the trail easement, and east of the utility corridor maintenance road. The habitat class of the wetland unit is PSS, dominated by salmonberry and Pacific willow (Salix lasiandra), and is classified as slope per the HNG classification system. Wetland 6 slopes east to west and is bordered on the west side by the maintenance road embankment. Wetland hydrology is supported by precipitation, shallow groundwater, and groundwater seeps. Upland vegetation consists of Douglas-fir, salmonberry, and western swordfern. The WDNR Stream Typing map (Appendix B: Figure 5) identifies a Type N waterbody where Wetland 6 is delineated.

Photographs 15 and 16 show typical habitat conditions for the slope wetland and adjacent upland habitat conditions. Wetland 7. Wetland 7 is a riverine wetland located within the utility corridor, west of the maintenance road, along the bank of Stream 1. Wetland 7 has a PFO Cowardin habitat class composed of red alder with an understory of salmonberry and piggyback-plant (Tolmiea menziesii). The wetland receives overbank flooding from Stream 1. The presence of water-stained leaves and hydrogen sulfide odor suggest long periods of soil saturation within the unit. The wetland is bordered by the maintenance road embankment in the utility corridor to the east (moderate intensity land use), and relatively undisturbed habitat to the west (low intensity land use). Photographs 20 and 21 show the habitat conditions of the wetland. Wetland 8. Wetland 8 is a riverine wetland located along Stream 1 and upstream of Wetland 7 on the east side of the maintenance road embankment within the utility corridor. Wetland hydrology is supported by overbank flows from Stream 1 and groundwater seeps. Wetland 8 and Stream 1 originate east of and outside of the trail easement corridor. Dominant vegetation within the portion of Wetland 8 within the trail easement is salmonberry, lady fern, and piggyback-plant. Wetland 8 has a PSS Cowardin class within the trail easement, and PFO habitat to the east and outside of the easement. The unit is an average of 35-feet wide, and the stream is approximately two feet wide. The upland buffer to the west of the unit is maintained and mowed within the utility corridor. Relatively undisturbed land use extends to the east. Photographs 23 and 24 show the wetland unit associated with Stream 1 and the upland buffer vegetation conditions adjacent to the wetland unit. Wetlands 9-16. Wetlands 9 through 16 consist of multiple slope wetlands with PSS habitat interspersed with uplands (e.g., mosaic) located north of Wetland 8 along the east and west sides of the maintenance road within the utility corridor and trail easement. Wetlands 9 through 16 have been lumped together due to similar habitat characteristics and functions per the 2014 Wetland Rating System for wetland/upland mosaics. Otak biologists based the delineation on limits of observed ponding and hydrophytic vegetation within the topographic depressions. The individual wetland areas are small (<0.1 acre individually) and supported by shallow groundwater seeps and saturated soil conditions. The individual wetlands are located within 100 feet of each other and meet the definition of regulated wetlands per JCC 18.22.710 despite being individually less than 0.1 acre in size. Wetland 15 is situated in a ditch along the east side of the maintenance road, but wetland conditions are assumed to be naturally occurring due to the groundwater seeps upslope and downslope of the road. Therefore, the wetland does not meet the definition of artificial per JCC 18.22.710. Dominant vegetation throughout the wetlands consists of spiraea and common rush. The adjacent upland areas are vegetated with salal, salmonberry and western swordfern. Buffer conditions include the disturbed utility corridor, forest land to the east, and recently logged areas to the west. Photographs 28 through 33 show the individual slope wetlands that make up the unit. Wetland 17. Wetland 17 is a slope wetland located within the utility corridor and trail easement, west of the maintenance road. The wetland is on a slope generally oriented east to west and south to north. Wetland 17 borders an auxiliary maintenance road to the west (Photograph 34 in Appendix E), and an upland berm to the north that is situated between Wetlands 17 and 19. Wetland 17 has a Cowardin habitat class of PSS and a vegetation community composed of spiraea and common rush. The unit is supported by shallow groundwater and seeps, and has saturated soil conditions. Upland vegetation adjacent to the wetland unit is dominated by salal and western swordfern. Wetland 18. Wetland 18 is a depressional wetland located west of the auxiliary road along the western boundary of the utility corridor and trail easement, west of Wetland 19. The Cowardin habitat class is PFO. The dominant vegetation is Pacific willow which covers most of the wetland. Ponded water is present in the depression. The unit is bordered by an upland berm to the west and a maintenance road to the east. Wetlands 17 and 18 are within the wetland buffer to the southwest and northwest. Western swordfern is present in the upland area to the west. A residential property is within 100-feet of the wetland to the west. Wetland 18 presumably overtops the auxiliary road prism and overflows to Wetland 19 during precipitation or snow melt events. Photograph 35 shows ponding and habitat conditions within Wetland 18. Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 10 Wetland and Stream Delineation Report Otak Wetland 19. Wetland 19 is a depressional wetland located within the utility corridor and trail easement underneath the overhead power lines. The wetland is bordered by maintenance roads along approximately 75 percent of its boundary. The wetland is seasonally ponded and supports amphibian breeding habitat. In addition to ponding, hydrogen sulfide odor was observed that indicates prolonged saturated soil conditions around the edges of the ponded area. Wetland 19 includes PSS and PEM Cowardin habitat classes. Dominant plant species include Pacific willow, red-stem dogwood (Cornus sericea), spiraea, and common rush. Photographs 36 and 37 show typical habitat conditions of the wetland unit. Wetland 20. Wetland 20 is depressional wetland located at the north end of the utility corridor and trail easement. Stream 3 flows into Wetland 20 and is assumed to infiltrate into well drained soils with gravels or similar. A culvert separates two areas of Wetland 20, which have been lumped into a single unit per the 2014 Rating System (Hruby) because watermarks are less than 6 inches different in elevation between the two areas. Wetland 20 does not have an observable outlet. The Cowardin classes within the unit are PFO, PSS, and PEM. Dominant vegetation includes red alder, spiraea, common rush, and small-fruited bulrush (Scirpus microcarpus). Himalayan blackberry (Rubus armeniacus) and mixed grass species dominate the upland buffer to the south. The wetland originates east of the study area and upslope along the Stream 3 corridor. Photographs 41 and 42 show the habitat conditions within the wetland unit. Wetland 21. Wetland 21 is a slope wetland in the young forest east of the utility corridor. The wetland is seasonally ponded and saturated, supporting PFO and PSS Cowardin classes. Groundwater emanates from seeps on the hillside and flows along the surface. Prolonged saturation is evidenced by iron ochre that was visible in small rivulets within the wetland. Herbaceous vegetation is interspersed with Pacific willow, salmonberry, and Himalayan blackberry patches. The upland buffer is densely forested with a single-aged stand of trees from previous logging activities. The portion of the buffer within the utility corridor west of Wetland 21 includes maintained shrubs and mixed grasses, and the gravel access road. 3.2 Wetland Functions, Ratings, and Buffer Widths Of the twenty-one individual wetlands delineated, several wetlands fall within a wetland/upland mosaic and are rated as a single unit per guidance in the 2014 Wetland Rating System. A total of 14 rating forms were completed. Eight wetland units are rated as Category III wetlands and six are rated as Category IV wetlands. Four Category IV wetland units have an HGM designation of slope, and two are depressional. Six Category III wetlands are depressional, and two are riverine. Wetland functions summaries are provided in Table 3-2, and wetland rating forms are provided in Appendix D. Generally, the wetlands provide low to moderate (scores of 4-6) water quality functions such as trapping and removing pollutants locally and within the watershed. Wetlands provided low to moderate site potential for hydrologic functions by storing water within the unit and having relatively small contributing basins. Slope wetlands generally do not provide the same water storage functions as depressional wetlands and rated lower. Hydrologic functions generally rated low to moderate (3-6) due to lack of pollutants in the surrounding landscape and absence of flooding downgradient of the wetlands. Depressional wetlands scored higher than slope wetlands due to characteristics that slow and retain surface water. Wetland habitat functions are moderate to high (5-8) due to moderate interspersion of habitat types, and a relatively high connectivity to undisturbed habitat and low to moderate land uses (e.g., forest land). Standard wetland buffer widths are based on wetland category and characteristics, habitat scores, and intensity of the impact of proposed adjacent land use per JCC 18.22.730. The majority of wetlands in the study area are located adjacent to, or within easements associated with utility corridor land use. The proposed trail construction will likely include a paved trail and will likely be constructed entirely within the utility corridor where maintenance roads currently exist. The proposed land use is categorized as moderate intensity land use per JCC 18.22.730(6) (Wetland Buffer Widths). Wetland buffers range from 40 to 225 feet for Category III and IV wetlands for moderate impact buffer width between 5-8 habitat scores. Throughout the project, buffers consist of moderately disturbed land within the utility Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 11 Wetland and Stream Delineation Report Otak corridor easements, relatively undisturbed forested land outside of the easements, and rural residential land uses. In general, the utility corridor is dominated by grass areas and scrub habitat from periodic maintenance, while the adjacent forested area is composed of coniferous stands less than 30 years old with deciduous species along the forest edges. Wetland buffers along the southern end of the study area include recently (2016) logged land areas and relatively undisturbed forest that extends south toward Anderson Lake State Park. The buffers associated with Wetland 1 and Wetland 2 are 110-feet wide and include recently logged land to the north, and forested land to the south. Wetland 3 has a buffer width of 40-feet and includes recently logged areas and a small portion of Wetlands 2 and 4. The buffer of Wetland 4 is 225-feet wide and consists of logged land to the west, and relatively undisturbed forested area to the east and south. The buffer of Wetland 4 overlaps Wetlands 2 and 3.

The 40-foot buffer associated with Wetlands 5 and 6 overlaps a portion of the maintenance road to the west and forested land to the east. Wetland 7 has a 110-foot buffer that extends west into forested land and east into the utility corridor. Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 13 Wetland and Stream Delineation Report Otak Wetland 8 has a 225-foot buffer which encompasses a portion of the utility corridor and extends east into forested land. Wetlands 9-16 are rated as a single unit and have a 40-foot buffer from the outer extent of each delineated wetland polygon. The buffers include land primarily within the utility corridor. Wetland 17 has a 40-foot buffer that situated within the disturbed utility corridor. Wetlands 18 and 19 have 60-foot buffers that include areas in the utility corridor and forested area to the west. Wetland 20 has a 110-foot buffer that includes forest and meadow habitats within and adjacent to the utility corridor and trail easement. Wetland 21 has a 40-foot buffer that includes the utility corridor and forested land to the east. 3.3 Fish and Wildlife Habitat Conservation Areas 3.3.1 Watercourses and Riparian Habitats Three streams are present within the study area. Two streams were delineated within the utility corridor and trail easements (Stream 1 and Stream 2), and one stream (Stream 3) was observed from the ROW and its boundaries estimated using LiDAR and aerial ESRI imagery, east of the trail easement near Wetland 20. Stream summaries are provided in Table 3-3. Stream classifications and riparian buffer widths were determined per JCC 18.22.630(b) (Prescriptive FWHCA Buffers), and JCC 18.22.630(1) (Stream Buffers). Stream typing is determined using the criteria in Washington Administrative Code (WAC) 222-16-030. WDNR mapped four streams within the study area (Appendix B: Figure 5). Otak biologists identified stream presence at one of the four mapped locations, in addition to two unmapped streams not listed on state or local resource mapping. Table 3-3.

The stream daylights between the primary maintenance road and the secondary maintenance road within the utility corridor, spanning approximately 25 feet before flowing into a culvert located under the secondary maintenance road and discharging into Wetland 7. The stream is approximately 24 inches in width. Stream 1 is mapped as a Type N (nonfish habitat) watercourse by the WDNR FPMAT. Type N streams are categorized into perennial or seasonal streams per JCC 18.22.630 (Stream Buffers). Stream 1 has a seasonal flow regime and is therefore typed Ns (nonfish, seasonal). Buffer widths are assigned based on the percent grade (i.e., slope) of type Ns streams. The slope of Stream 1 is less than 20 percent and has a 50-foot buffer width. The stream buffer includes forested areas to the east and west, and the maintenance road and disturbed utility corridor. Photographs 20-27 show the flow path of Stream 1, associated wetlands (Wetlands 7 and 8), and buffer conditions. Stream 2 is approximately 12” in width and 40 feet long. The stream is fed by a groundwater seep emanating along the hillslope, and flows at the surface for approximately 40 feet before infiltrating in an upland field. Stream Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 14 Wetland and Stream Delineation Report Otak 2 is not mapped by local or state mapping resources. Indicators of OHWM included gravel sorting, bed and bank, scour, and surface water. Buffer vegetation includes a dense salmonberry community. Photograph 39 shows the confined stream channel and buffer vegetation. A portion of the stream buffer is mowed and maintained. Stream 3 is located east of Wetland 20 and outside of the easement boundary. The stream discharges to Wetland 20 at the bottom of the hillside. The stream boundary is estimated using lidar imagery and observations made in the field. Stream 4 is not identified by the WDNR FPMAT mapper. The stream is type Ns with less than 20 percent grade, resulting in a 50-foot buffer width per JCC 18.22.630. The stream buffer is composed of red alders trees and salmonberry. Photograph 40 shows the general riparian habitat associated with the stream and typical buffer conditions. 3.3.2 Fish and Wildlife Habitat Conservation Areas Per the Washington Natural Heritage Program, no sensitive plant species or natural heritage features are identified on the Washington Wetlands of High Conservation Value Map Viewer within the project vicinity (WDNR 2022a). No sensitive plant species were observed during the field survey in March 2022 or May 2023. No designated habitats of local importance are present within the study area, including locally important species or habitats per JCC 18.22.630(2) (Buffers for Other FWHCAs). The project occurs within Puget Sound Recovery Domain for Puget Sound Chinook Salmon (DPS) and Puget Sound Steelhead (DPS) protected under the ESA (NOAA 2022). However, no waterbodies within the study area are mapped for the presence of listed fish species through WDFW PHS or SWIFD mapping. All streams within the study area are typed as non-fish habitat. The USFWS IPaC tool lists the potential presence of five threatened federally listed species, one endangered species, and one candidate species. The IPaC tool does not map any designated critical habitats within the study area. WDFW PHS does not document these species or nests occurring within the study area. Otak biologists visually surveyed for suitable habitat and presence of federally listed species in the easement corridor during the field visit on March 2 through March 4, 2022, and on May 10, 2023. However, no listed species or suitable habitats were observed due to recent logging activities, periodic maintenance activities (e.g., utility corridor), or other site disturbances. Specifically, suitable habitat for marbled murrelet within and adjacent to the study area was assessed using definitions of marbled murrelet habitat per USFWS Guidance for Identifying Marbled Murrelet Nest Trees in Washington State (2012). The USFWS defines the range of nest trees in Washington as all areas within 55 miles of marine waters. These trees must have the presence of platforms, sufficient cover, and other tree and forest area characteristics. Nesting platforms are defined as “relatively flat surface[s] > 33 feet above the ground in the live crown of a coniferous tree” (USFWS 2012). The width of the platform must be a minimum of four inches wide. A single nesting platform can support a nest, and presence of these platforms can be condensed or dispersed throughout the forest. Cover of the nest platforms must be present in order to provide chicks protection from predation, and can consist of vertical or horizontal cover above or to the side of the nest. Suitable nesting habitat was not observed within the study area. The study area is mostly located on or adjacent to active forest lands or roadways. The age of the existing forest stands range from 17 to 32 years old along the north-south aligned trail easement. Aerial imagery on Google Earth (2022) shows that a majority of the forested utility corridor and surrounding areas was clear cut between 1990 and 2005. The existing forested stands do not meet size criteria for platform widths in the study area. No deformities of branches were observed such as dwarf mistletoe that would provide suitable nesting habitat. 3.4 Regulatory Summary Wetlands and streams within the study area are assumed to be regulated by local, state, and federal agencies. Four wetlands are assumed to be regulated by the USACE, and all wetlands are assumed to be regulated by Ecology and the County. Streams onsite are assumed to be regulated by state (Ecology and WDFW) and local (Jefferson County) agencies, whereas only Stream 1 is assumed to be regulated by the USACE. Riparian buffers Olympic Discovery Trail – Larry Scott Trail to Anderson Lake State Park 15 Wetland and Stream Delineation Report Otak are regulated by Jefferson County per JCC 18.22.630 (Protection Standards). Impacts to streams and their buffers require prior authorization and coordination with regulatory agencies. 3.4.1 U.S. Army Corps of Engineers The Environmental Protection Agency (EPA) and USACE regulate wetlands and other waters of the United States (WOTUS) under Section 404 of the Clean Water Act (CWA). The agencies are currently interpreting WOTUS consistent with the pre-2015 regulatory regime (EPA 2021) per 40 CFR 230.3(s). The WOTUS definition includes traditional navigable waters (TNW), wetlands adjacent to TNWs, non-navigable tributaries to TNWs [identified as relatively permanent waters (RPWs) and non-RPWs), and wetlands that abut or have a significant nexus to such tributaries. Discharge of fill material into these waterbodies is regulated under Section 404 and 401 of the CWA. Puget Sound and Discover Bay are classified as a TNW. Stream 1 is classified a RPW because it is assumed to flow continuously for at least three months out of the year and has a surface connection to Discovery Bay and Puget Sound. Streams 2 and 3 do not appear to have a surface connection to a TNW, and therefore do not appear to qualify as either RPWs or non-RPWs. Wetlands 2, 3, 4, 6, 7, and 8 are assumed to be within federal jurisdiction under the CWA. Wetlands 2 and 3 are assumed to have a hydrological connection to the outlet stream from Anderson Lake near Anderson Lake Road. Wetland 4 is assumed to have a hydrological connection to Anderson Lake, which outlets at its southwest corner to a tributary that discharges to Discovery Bay. Wetland 6 is located along a mapped drainage path that presumably discharges to Discovery Bay. Wetland 7 and Wetland 8 are located adjacent to Stream 1, a RPW which outflows to Discovery Bay. Wetlands 1, 5, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, and 21 are assumed not to be regulated by the USACE because the definition of WOTUS provided at 40 CFR 230.3(s) is not met. These wetlands are not adjacent to TNWs, RPWs, or non-RPWs, and do not have a significant nexus to TNWs, RPW, and non-RPWs. Therefore, these wetlands are not likely to significantly affect the chemical, physical, and biological integrity of downstream navigable waters (Table 4-1 Federal Jurisdiction of Wetland and Streams in Study Area). Table 4-1.

Stream 2 No Connection Not Regulated Stream 3 No Connection Not Regulated 3.4.2 Washington State Department of Fish and Wildlife WDFW requires issuance of a Hydraulic Permit Approval (HPA) prior to any activities that may directly or indirectly affect streams or associated aquatic resources considered as waters of the state per the Regional Code of Washington (RCW) 90.48.020. Construction in or near state waters that will “use, divert, obstruct, or change the natural flow or bed of any of the salt of fresh waters in the state.” (RCW 77.55.011(11) require an HPA. Streams 1, 2, and 3 are considered waters of the state and will require an HPA if they will be impacted. Activities included in the Hydraulic Code Rules (Chapter 220-660 WAC) require an HPA. 3.4.3 Washington State Department of Ecology Ecology regulates activities in wetlands and streams under Section 401 of the CWA through the Water Quality Certification process. Ecology has authority over discharge into all wetlands and streams and can impose buffers and compensatory mitigation for impacts per RCW 90.48 (Water Pollution Control Act) depending on the proposed project and amount of impacts to aquatic resources. All wetlands in the study area assumed to be regulated by Ecology. 3.4.4 Local Jurisdiction – Jefferson County Wetland and riparian buffers are regulated by Jefferson County per JCC 18.22.700 (Wetlands) and JCC 18.22.600 (Fish and Wildlife Habitat Conservation Areas), respectively. Exemptions for non-federally regulated Category IV wetlands do not apply to any of the wetlands on site per JCC 18.22.710 (3)(g) because all wetlands score higher than 5 points for habitat functions based on the 2014 Wetland Rating System and they are in an upland/wetland mosaic.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. W1 X X 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.

Mature forests – Stands with average diameters exceeding 21 in (53 cm) dbh; 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; 80-200 years old west of the Cascade crest. Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak component is important (full descriptions in WDFW PHS report p. 158 – see web link above). Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Westside Prairies: Herbaceous, non-forested plant communities that can either take the form of a dry prairie or a wet prairie (full descriptions in WDFW PHS report p. 161 – see web link above). Instream: The combination of physical, biological, and chemical processes and conditions that interact to provide functional life history requirements for instream fish and wildlife resources. Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report – see web link on previous page). Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth in soils, rock, ice, or other geological formations and is large enough to contain a human. Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation. Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western Washington and are > 6.5 ft (2 m) in height. Priority logs are > 12 in (30 cm) in diameter at the largest end, and > 20 ft (6 m) long.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. W2 X X 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.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. W3 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.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. W4 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.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. 5 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. 5 Wetland name or number ______ Wetland Rating System for Western WA: 2014 Update 5 Rating Form – Effective January 1, 2015 DEPRESSIONAL AND FLATS WETLANDS Water Quality Functions - Indicators that the site functions to improve water quality D 1.0.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. 6 X X X 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. 6 Wetland name or number ______ Wetland Rating System for Western WA: 2014 Update 11 Rating Form – Effective January 1, 2015 SLOPE WETLANDS Water Quality Functions - Indicators that the site functions to improve water quality S 1.0.

HABITAT FUNCTIONS - Indicators that site functions to provide important habitat H 1.0. Does the site have the potential to provide habitat? H 1.1. Structure of plant community: Indicators are Cowardin classes and strata within the Forested class. Check the Cowardin plant classes in the wetland. Up to 10 patches may be combined for each class to meet the threshold of ¼ ac or more than 10% of the unit if it is smaller than 2.5 ac. 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.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. W7 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.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. W8 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.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. W9 X X X 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. W9 Slope wetlands are rated per guidance for identifying wetland units in a patchwork on the landscape (mosaic).Multiple slope wetlands that meet criteria in Section 4.3 of the Wetland Rating System for Western WA: 2014: Update are rated as a single unit.

Aspen Stands: Pure or mixed stands of aspen greater than 1 ac (0.4 ha). Biodiversity Areas and Corridors: Areas of habitat that are relatively important to various species of native fish and wildlife (full descriptions in WDFW PHS report). Herbaceous Balds: Variable size patches of grass and forbs on shallow soils over bedrock. Old-growth/Mature forests: Old-growth west of Cascade crest – Stands of at least 2 tree species, forming a multi- layered canopy with occasional small openings; with at least 8 trees/ac (20 trees/ha ) > 32 in (81 cm) dbh or > 200 years of age. Mature forests – Stands with average diameters exceeding 21 in (53 cm) dbh; 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; 80-200 years old west of the Cascade crest. Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak component is important (full descriptions in WDFW PHS report p. 158 – see web link above). Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Westside Prairies: Herbaceous, non-forested plant communities that can either take the form of a dry prairie or a wet prairie (full descriptions in WDFW PHS report p. 161 – see web link above). Instream: The combination of physical, biological, and chemical processes and conditions that interact to provide functional life history requirements for instream fish and wildlife resources. Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report – see web link on previous page). Caves: A naturally occurring cavity, recess, void, or system of interconnected passages under the earth in soils, rock, ice, or other geological formations and is large enough to contain a human. Cliffs: Greater than 25 ft (7.6 m) high and occurring below 5000 ft elevation. Talus: Homogenous areas of rock rubble ranging in average size 0.5 - 6.5 ft (0.15 - 2.0 m), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Snags and Logs: Trees are considered snags if they are dead or dying and exhibit sufficient decay characteristics to enable cavity excavation/use by wildlife. Priority snags have a diameter at breast height of > 20 in (51 cm) in western Washington and are > 6.5 ft (2 m) in height.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. W17 X X X 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.

Mature forests – Stands with average diameters exceeding 21 in (53 cm) dbh; 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; 80-200 years old west of the Cascade crest. Oregon White Oak: Woodland stands of pure oak or oak/conifer associations where canopy coverage of the oak component is important (full descriptions in WDFW PHS report p. 158 – see web link above). Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Westside Prairies: Herbaceous, non-forested plant communities that can either take the form of a dry prairie or a wet prairie (full descriptions in WDFW PHS report p. 161 – see web link above). Instream: The combination of physical, biological, and chemical processes and conditions that interact to provide functional life history requirements for instream fish and wildlife resources. Nearshore: Relatively undisturbed nearshore habitats. These include Coastal Nearshore, Open Coast Nearshore, and Puget Sound Nearshore. (full descriptions of habitats and the definition of relatively undisturbed are in WDFW report – see web link on previous page).

Are the water levels in the entire unit usually controlled by tides except during floods? 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. 18 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. 18 The wetland fringe to the east is inundated by overbank flooding, over surface flows are assumed to run through the wetland during times of high precipitation.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. W19 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.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. 20 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. 20 The wetland fringe to the east is inundated by overbank flooding, over surface flows are assumed to run through the wetland during times of high precipitation.

Are the water levels in the entire unit usually controlled by tides except during floods? 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. 21 X X X 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. 21 Wetland name or number ______ Wetland Rating System for Western WA: 2014 Update 11 Rating Form – Effective January 1, 2015 SLOPE WETLANDS Water Quality Functions - Indicators that the site functions to improve water quality S 1.0.

Monroe Avenue NE Storm System Improvements; Renton, Washington Wetland Scientist—Otak completed an alternatives analysis of a combination of stormwater infiltration facilities and other strategies to prevent historic flooding along Monroe Avenue. Additionally, water quality treatment will be provided for runoff as applicable. Otak provided hydrologic and hydraulic modeling of the subbasin to estimate existing flows, assess the capacity of the existing infiltration system, and size the proposed improvements. Otak also developed stormwater, flow control, and water quality solutions for the urbanized 211- acre subbasin in the Renton Highlands area. The improved stormwater conveyance system will convey the 25- year peak flow rate and reduce the probability of roadway overtopping during the 100- year event, thus reducing the risk of flooding along Monroe Avenue NE and adjacent private properties. The considered water quality solutions included green stormwater infrastructure like bioretention, compost-amended vegetated filter strip and biofiltration swale, and bioswale.
