This report is the second in a series of reports. The first report provided information on the wetland impacts that will occur from the Howard Street extension, this first report, Sims Way Howard Road Wetland Report (Landau Associates 2008) determined that the proposed Howard Street Improvements would impact approximately 3.7 acres of mowed pasture wetlands. This second report presents the delineation of proposed the mitigation site which is currently under private ownership. Proposed mitigation is proposed to be a combination of preservation and enhancement. The third in this series of reports will be the complete mitigation report to provide compensation for unavoidable wetland impacts from the Howard Street project. This report is the delineation of offsite private properties (Markley and Gunstone-White) which contain wetland areas. South of the Gunstone-White wetlands is the Roberts property. The Loggy Soils report (Loggy Soil and Wetland Consulting 2006) provided a delineation of the Roberts Property. Additionally the Loggy Soil report is included as Appendix F of this document. The Roberts property wetlands along with the Markley and Gunstone-White property wetlands support a diverse range of native plants and provide forested habitat. The wetlands impacted by the Howard Street project and the proposed areas for wetland mitigation have been preliminarily reviewed by the Washington State Department of Ecology (Rick Mraz). Federal, state and local information was reviewed prior to the field work to delineate the sites. The delineation work was completed in accordance with federal, state and city regulations. The results of the delineation determined these wetlands are highly functioning Category II and Category III wetlands. These wetlands are of a much higher quality than the wetlands impacted by the Howard Street project; therefore, these wetlands could be used to provide mitigation for impacts to existing wetlands along the Howard Street corridor. 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES iii FACT SHEET Site Information Location Project Information Site Name(s) Markley Property, Gunstone-White Property County Jefferson City (or nearest City) Port Townsend Section (¼, ¼), Township, Range Section 9, Township 30N, Range 01W Latitude, Longitude (GIS verified) 48◦ 06’ 37.71”N, -122◦ 48’ 20.60”W Watershed Quilcene-Snow WRIA Number WRIA 17 Summary of Delineated Wetland(s), including, wetland type, wetland functions, buffer width, and wetland size: Designation: Type within Study Area (Cowardin/HGM): Category: Highest Scoring Function: Buffer Width: Size: Markley Wetland 1 PFO- PSS/Depression II Water Quality 150 47,369.65 sf Markley Wetland 2 PFO/Depression II Water Quality 150 29,340.98 sf Markley Wetland 3 PFO- PEM/Depression III Habitat 80 2,951.13 sf Markley Wetland 4 PFO- PSS/Depression II Habitat 150 6,148.76 sf Gunstone-White Wetland PFO- PSS/Depression III Water Quality 150 8,455.82 sf* PFO = Palustrine Forested Key: PSS = Palustrine Scrub-Shrub PEM = Palustrine Emergent Rating form used to determine wetland category are included in Appendix E. Summary of project, including proposed type and location of work, goals and objectives, wetland functions, impacted and mitigated (note assessment method used), and the general design concept (include where it has been done before). This delineation provided information on wetlands in the City of Port Townsend that are intended to be preserved and enhanced in exchange for work that will impact low quality wetlands south of these properties. The delineation was provided on the Markley and Gunstone-White properties which are proposed as mitigation for work on the Howard Street alignment which will impact existing low quality Category III wetlands. The Markley site provides 85,810.52 sf of wetlands or 1.97 acres of wetlands. Adding that to the Gunstone-White and Roberts properties of 0.88 acres, the total is 2.85 acres of wetland preservation. *Gunstone-White wetland sf on this chart is only the portion delineated for this report and does not include the southern portion of the site, owned by Roberts, which was delineated by Loggy Soil and Wetland Consulting, December 2006. The wetland on the Roberts property and the right of way (not including Lot 6) is 29,953 sf (0.69 acres); therefore, the total sf of wetland on the Gunstone-White and Roberts properties is 38,408.82 sf or approximately 0.88 acres. 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES iv TABLE OF CONTENTS 1.0 INTRODUCTION Page 1-1 1.1 SITE DESCRIPTION 1-1 1.2 REGULATORY BACKGROUND 1-2 2.0 METHODS 2-1 2.1 WETLAND AND SURFACE WATERS INVESTIGATION 2-1 2.1.1 Background Information Review 2-1 2.1.2 Wetland Delineation 2-1 2.2 WETLAND CLASSIFICATION, RATING, AND BUFFER WIDTH 2-2 3.0 RESULTS 3-1 3.1 BACKGROUND INFORMATION REVIEW 3-1 3.2 FIELD INVESTIGATION 3-2 3.2.1 Markley Property Wetlands 3-3 3.2.1.1 Markley Wetland 1 Vegetation 3-3 3.2.1.2 Markley Wetland 1 Soils 3-4 3.2.1.3 Markley Wetland 1 Hydrology 3-4 3.2.1.4 Markley Wetland 1 Determination and Rating 3-4 3.2.1.5 Markley Wetland 2 Vegetation 3-4 3.2.1.6 Markley Wetland 2 Soils 3-5 3.2.1.7 Markley Wetland 2 Hydrology 3-5 3.2.1.8 Markley Wetland 2 Determination and Rating 3-5 3.2.1.9 Markley Wetland 3 Vegetation 3-5 3.2.1.10 Markley Wetland 3 Soils 3-6 3.2.1.11 Markley Wetland 3 Hydrology 3-6 3.2.1.12 Markley Wetland 3 Determination and Rating 3-6 3.2.1.13 Markley Wetland 4 Vegetation 3-6 3.2.1.14 Markley Wetland 4 Soils 3-7 3.2.1.15 Markley Wetland 4 Hydrology 3-7 3.2.1.16 Markley Wetland 4 Determination and Rating 3-7 3.2.1.17 Upland Characterization 3-7 3.2.2 Gunstone –White Wetland 3-8 3.2.2.1 Gunstone-White Wetland Vegetation 3-9 3.2.2.2 Gunstone-White Wetland Soils 3-9 3.2.2.3 Gunstone-White Wetland Hydrology 3-9 3.2.2.4 Gunstone-White Wetland Determination and Rating 3-9 3.2.2.5 Upland Characterization 3-10 3.2.2.6 Area investigations 3-10 3.2.3 Summary 3-11 4.0 REGULATORY ASSESSMENT 4-1 5.0 CONCEPTUAL MITIGATION 5-1 6.0 USE OF THIS REPORT 6-1 7.0 REFERENCES 7-1 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES v FIGURES Figure 1 Vicinity Map Title 2 Study Area Map 3 Wetland Delineations 4 Existing Trails and Utilities 5 Zoning and Open Space TABLES Table 1 Methods for Wetland Determination Title 2 Wetland Delineation Summary 3 Summary of Characteristics of Wetlands and Upland Areas APPENDICES Appendix A Background Information Review Figures Title B Soil Profile Reports C Sampling Point Data Sheets D Selected Site Photographs E Wetland Rating Forms F Loggy Soil and Wetland Consulting ReportӢ 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 1-1 1.0 INTRODUCTION Landau Associates, Inc., under contract to the City of Port Townsend (City), provided a delineation of wetlands on the Markley and Gunstone-White properties in Port Townsend, Jefferson County, Washington. These properties are just north of the proposed extension of Howard Street. The purpose of the study was to determine if the wetlands on these properties could be used to satisfy mitigation requirements for impacts to wetlands from the Howard Street project. The Markley and Gunstone-White properties are quite large, forested and support a diverse native plant population. Preserving and enhancing these wetlands would provide wetland mitigation under the Port Townsend Municipal Code (PTMC), Critical Areas Section 19.05.110 subsection F. This PTMC section allows wetland preservation and buffer enhancement as mitigation for wetland impacts. Landau Associates was hired to provide a wetland delineation report to the City including determining the category and size of the wetlands and assisting with determination of the amount of mitigation these wetland sites could provide. This report is the second in a series of reports. The first report provided information on the wetland impacts that will occur from the Howard Street extension, this first report, Sims Way Howard Road Wetland Report (Landau Associates 2008) determined that the proposed Howard Street Improvements would impact approximately 3.7 acres of mowed pasture wetlands. This second report presents the delineation of proposed the mitigation site which is currently under private ownership. Proposed mitigation is proposed to be a combination of preservation and enhancement. The third in this series of reports will be the complete mitigation report to compensate for unavoidable wetland impacts from the Howard Street project. This report is the delineation of offsite private properties (Markley and Gunstone-White) which contain wetland areas. South of the Gunstone-White wetlands is the Roberts property. The Loggy Soils report (Loggy Soil and Wetland Consulting 2006) provided a delineation of the Roberts Property. Additionally the Loggy Soil report is included as Appendix F of this document. The Roberts property wetlands along with the Markley and Gunstone-White property wetlands support a diverse range of native plants and provide forested habitat. The wetlands impacted by the Howard Street project and the proposed areas for wetland mitigation have been preliminarily reviewed by the Washington State Department of Ecology (Rick Mraz). 1.1 SITE DESCRIPTION The study area is bounded by Discovery Road and 20 th Street and this delineation was limited to the undeveloped properties of Markley and Gunstone-White in Jefferson County, WRIA 17 Quilcene- 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 1-2 Snow (Township 30 North, Range 01 West and Section 9). These properties are south of 20 th Street, north of Discovery Road, east of the Rainier Street alignment and west of Eddy Street in Port Townsend, Washington (see Figure 1 and Figure 2). Currently, the properties are vacant with hard-packed pedestrian and bike trails located at the approximate location of the street right-of-way for Howard and 15 th Street (see Figure 4). Many of the existing trails line up with existing utility alignments. To the north, south and east of these properties, housing developments are being constructed. To the west, adjacent to the northern portion of the Markley site, there is a small section of Open Space. South of the existing Open Space on the west side of the Markley site, there are plans for development per communication with the property owner (Scott, N., 2009, personal communication). The City desires to save the existing wetlands as City Open Space and as mitigation for the Howard Street project. With development encroaching on all sides of these two sites, preserving these sites would benefit the City by providing mitigation, maintaining existing utility access corridors, maintain existing trial corridors and by increasing and providing connections to existing Open Space. The properties are zoned Residential II – Medium Density Single-Family, however there is also an open space connection designation on these properties in the City of Port Townsend’s Comprehensive Land Use Plan. The Residential II Zoning allows development of up to eight dwelling units per acre with a minimum lot size for a single-family dwelling of 5,000 sq ft (Port Townsend 2009a; Zoning Map). This zoning designation also allows for duplexes, triplexes and fourplexes provided the lot size is increased. These properties could be developed with duplex/triplex/fourplex under current zoning regulations (see Figure 5) or up to 104 total dwelling units (to clarify one fourplex = four dwelling units). The surrounding area is a mix of zonings including Residential II, Residential III, Public Open Space/Mixed Use, and Residential IV Multi-family. Areas to the north and east are being developed with residential housing, the area to the west is going through the permit process for development, and the area to the south is being developed with commercial enterprises. The Markley, Gunstone-White, and Roberts property delineated areas are shown on Figure 2. The Gunstone-White property has one wetland that ends at the trail/utility access road. Adjacent to that wetland to the south is the wetland that was previously delineated by Loggy Soils and that report is Appendix F of this document. 1.2 REGULATORY BACKGROUND The wetlands delineated for this report could be used as mitigation for the Howard Street project to the south. The wetlands in the Howard Street right-of-way (ROW) are within the same drainage basin and preservation and enhancement as mitigation is allowed per PTMC 19.05.110 subsection F.8.a. Therefore, preserving and enhancing the wetlands delineated in this report would fulfill mitigation 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 1-3 requirements. Per the PTMC, the preservation and enhancement ratio ranges from 1:10 up to 1:20 and is determined on a case-by-case basis, depending on the quality of the wetlands being mitigated and the quality of the wetlands being preserved. The wetlands on the Markley and Gunstone-White properties all rated as very high Category II or Category III wetlands. These wetlands support a diverse native plant population, provide snags for habitat, and provide an excellent opportunity to increase the existing Open Space and recreation for residents and visitors to Port Townsend. Most of the Howard Street wetlands that will be impacted are within a mowed field and have significantly less plant diversity and provide much less habitat than the Markley and Gunstone-White property wetlands. The main function is for water quality. Additionally development is occurring on properties adjacent to the Markley and Gunstone-White wetlands. Thus, there is a limited opportunity to ensure preservation of these areas. Wetlands and certain waterways are regulated by federal, state, and local governmental agencies and compliance with one agency does not always fulfill permitting requirements of any other agencies. The U.S. Army Corps of Engineers (USACE) has developed mandatory procedures for identifying and delineating wetlands subject to regulation under Section 404 of the CWA (USACE 1987, 2008). Ecology has developed similar procedures for use by all state agencies in the application of any state laws and regulations as well as by any city or county in the implementation of any regulations under the Growth Management Act. This report documents the wetland delineation procedures and results for wetland mitigation for the Howard Street project in accordance with local, state, and federal guidelines. According to the regulations, the following regulatory agencies could be involved with the project: • U.S. Army Corps of Engineers (USACE) authorizes discharge of dredged or fill material into the “waters of the U.S.” under Section 404 of the Clean Water Act (CWA) (EPA, USACE 2007). • Washington State Department of Ecology (Ecology) has administrative oversight of Section 401 of the CWA or, if there are no requirements under section 404 of the CWA, Ecology regulates wetlands using the State Water Pollution Control Act (RCW 90.48). • The Washington State Department of Fish and Wildlife (WDFW) requires Hydraulic Project Approval (HPA) for any work in, on, over or adjacent to a water of the state. • The City of Port Townsend Municipal Code (PTMC; Port Townsend 2009b) Critical Areas Section 19.05.110. Based on conversations with the USACE, the Howard Street project will be regulated by USACE and qualifies as a Nationwide Permit 14 for linear transportation projects and will impact approximately 0.37 acres of existing mowed Category III wetlands. Based on this information, Ecology will regulate under Section 401 of the CWA. Per the letter dated February 21, 2009 from Chris Byrnes with WDFW to the City of Port Townsend, an HPA is not required for the Howard Street work (WDFW 2009). The 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 1-4 Markley and Gunstone-White wetlands can provide for approximately 2.16 acres of wetland preservation of high quality Category II and III wetlands. The Roberts property and right of way wetland has the potential to provide an additional 0.69 acres of preservation for an approximate total of 2.85 acres of preservation. Using the 10 to 1 minimum required from the PTMC for preservation and enhancement (3.7 acres total), an additional 0.85 acres of buffer enhancement will be the minimum required to offset the wetland impacts from the Howard Street project. If a 12:1 preservation and enhancement ratio is required, 4.44 acres of preservation and enhancement would be required and 1.59 acres of buffer enhancement will be needed to compensate wetland impacts at Howard Street.䴀 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 2-1 2.0 METHODS 2.1 WETLAND AND SURFACE WATERS INVESTIGATION Landau Associates conducted the wetland investigation in accordance with the USACE Wetland Delineation Manual (USACE 1987); the USACE Regional Guidance letter on the 1987 Manual (USACE 1994); the USACE Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (USACE 2008); and the Ecology Washington State Wetlands Identification and Delineation Manual (Ecology 1997). The USACE and Ecology recommend gathering preliminary data and synthesis of available background information, followed with a field investigation. 2.1.1 BACKGROUND INFORMATION REVIEW Landau Associates reviewed the following public domain resources to determine existing conditions and potential wetlands and other “waters of the U.S.” within the study area: • U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory map (USFWS 1981 to present) • City of Port Townsend Environmentally Sensitive Area map (City of Port Townsend 2009c) • USDA Natural Resources Conservation Service (NRCS) Soil Survey Geographic database (USDA, NRCS 2009a) • National Hydric Soils List (USDA, NRCS 2009b) • Federal Emergency Management Agency (FEMA) flood data (FEMA 1982a,b) • Precipitation data [USDA, NRCS 2002; Weather Underground 2009) • Washington State Department of Fish and Wildlife (WDFW) Priority Habitat and Species Data (July 2009). 2.1.2 WETLAND DELINEATION Both USACE and Ecology outline a three-parameter approach to determine the presence or absence of wetlands that requires evaluating vegetation, soil, and hydrology (Table 1). Landau Associates scientists completed the field delineation. An area is determined to be wetland if all of the following three criteria are met (also see Table 1): • The dominant vegetation is hydrophytic • Soils are hydric • Wetland hydrology is present. 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 2-2 The wetland boundaries were delineated using numbered flagging. A Global Positioning System (GPS) device capable of submeter accuracy was used to collect locations of wetland boundary flags and sampling plots. 2.2 WETLAND CLASSIFICATION, RATING, AND BUFFER WIDTH Any wetlands identified as part of this project were classified according to the USFWS’s Cowardin classification system (Cowardin et al. 1979) and the USACE’s hydrogeomorphic (HGM) classification system (Brinson 1993). Wetlands were rated according to the Washington State Wetland Rating System for Western Washington (Hruby 2004), which is accepted practice by the City. This system categorizes wetlands based on their existing functions, including water quality, hydrology, and habitat, as well as the wetland’s rarity, sensitivity to disturbance, and ability to replace. Wetland buffers were determined according to PTMC, which relies on assigned wetland ratings.⼀ 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 3-1 3.0 RESULTS 3.1 BACKGROUND INFORMATION REVIEW Wetlands The National Wetlands Inventory Map (USFWS 1981 to present) does not identify any wetlands in the immediate vicinity of the study area (see Appendix A). The City’s Environmentally Sensitive Area mapping identifies wetlands within the study area and identifies the area as part of a Critical Drainage Corridor (see Appendix A). Soils The Soil Survey Geographic Database for Jefferson County, Washington (USDA, NRCS 2004) identifies one soil series within the study area (see Appendix A). Complete soil profile reports are included in Appendix B. The soil series in the study area are as follows: • Clallam gravelly sandy loam, 0 to 15 percent slopes (Jefferson Co. unit symbol: CmC) consists of moderately deep to densic materials, moderately well drained soils formed in glacial till over very compact glacial till. (USDA, NRCS 2004). The Clallam soil series within the project area is not classified as hydric on the National Hydric Soils List (USDA, NRCS 2009b). Floodplains Full coverage of the study area through FEMA flood maps, Jefferson County (FEMA 1982a) and Port Townsend (FEMA 1982b) was not available. However, the surrounding area is primarily designated as Zone C which designates areas of minimal flooding. There does not appear to be a flood zone (100-year) within or near the project area (see Appendix A). Land Use The Markley and Gunstone-White properties are zoned Residential II – Medium Density Single- Family which allows development of up to eight dwelling units per acre with a minimum lot size for a single-family dwelling at 5,000 sq ft (see Figure 5). This zoning designation also allows for duplexes, triplexes, and fourplexes with increased lot sizes. Based on the number of lots on the Markley and Gunstone-White properties this area could theoretically provide up to 104 dwelling units. The surrounding area is a mix of zonings including Residential II, Residential III, Public Open Space/Mixed Use, and Residential IV Multi-family. Areas to the north and east are being developed with residential housing, the area to the west is planned for development and the area to the south is being developed with commercial enterprises. The trails in the area also serve as public utility easements for water and sanitary sewer lines. 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 3-2 Washington State Department of Fish and Wildlife The Priority Habitat and Species (PHS) data does not show the wetlands or any priority habitats in the project area. The PHS data also does not show any priority species in the project area.

On the September 11, 2009 site visit, Rick Mraz with the Department of Ecology and Judy Surber with the City of Port Townsend came out on the site visit to view the wetland mitigation site. All field investigations were completed during the growing season. The weather during the field investigation was partially overcast to sunny, and the temperatures ranged from low 60s to low 70s in August and September and 45 in October (degrees Fahrenheit) (see Appendix A). Eight sampling plots (SP) were recorded within different plant community types encountered at the Markley site in areas suspected to meet the mandatory wetland criteria and in the nearby upland to determine corresponding wetland/upland boundaries. Four SP were recorded on the Gunstone-White (GW) site, three in the upland and one within the wetland. For both sites the wetland boundaries were delineated using numbered flagging. A summary of the delineated systems, including classifications and buffer requirements, is presented in Table 2. A summary of the characteristics of the wetlands and upland areas is presented in Table 3. The locations of the sampling plots and delineated systems are shown on ⥢ 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 3-3 Figure 3, and the completed data sheets and site photographs are presented in Appendix C and Appendix D, respectively. Wetland rating information is recorded in Appendix E. 3.2.1 MARKLEY PROPERTY WETLANDS The Markley site contains four wetlands: Markley Wetland 1, Markley Wetland 2, Markley Wetland 3, and Markley Wetland 4. All four wetlands are depressional and primarily receive their hydrology from a high groundwater table. They have similar vegetation, soils, hydrology, and are surrounded by forested upland. Markley Wetland 1 is approximately 47,369.65 sf or 1.08 acres and is located in between Rainier Street and the trail connecting to Howard Street (see Figure 3). Markley Wetland 2 is approximately 29,340.98 sf or 0.67 of an acre and located north of Markley Wetland 1. Markley Wetland 3 is the smallest at 2,951.13 sf or approximately 0.07 of an acre and located north of Markley Wetland 2, and Markley Wetland 4 is 6,148.76 sf or approximately 0.14 of an acre and is located directly to the east of Markley Wetland 3. The Markley Wetlands are not shown on the National Wetlands Inventory map, but are shown on the City’s Environmentally Sensitive Area mapping as two wetland areas. The vegetation, soils, and hydrology for the wetlands are as follows: • Markley Wetland 1 - described in data sheets M-SP-1 and M-SP-2 • Markley Wetland 2 - described in data sheets M-SP-4 • Markley Wetland 3 - described in data sheets M-SP-6 • Markley Wetland 4 - described in data sheets M-SP-8 • Markley Wetland uplands - described in data sheets M-SP-3, M-SP-5, and M-SP-7. 3.2.1.1 Markley Wetland 1 Vegetation The Markley Wetland 1 is dominated by hydrophytic vegetation, primarily scrub-shrub and forested with emergent vegetation underneath. The dominant plant species found in this wetland includes: • Red alder (Alnus rubra, FAC) • Nootka rose (Rosa nutkana, FAC) • Slough sedge (Carex obnupta, OBL) • Water-parsley (Oenanthe sarmentosa, OBL). Additional non-dominant species found in Markley Wetland 1 include red elderberry (Sambucus racemosa, FACU), Douglas spirea (Spiraea douglasii, FACW), and trailing blackberry (Rubus ursinus, FACU). 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 3-4 3.2.1.2 Markley Wetland 1 Soils The soil at sample plots M-SP-1 and M-SP-2 was generally black (10YR 2/1) loam from 0 to 5 inches in M-SP-1 and from 0 to 4 inches in M-SP-2. Below was grayish brown (2.5Y 5/2) sandy loam from 5 to 16 inches with yellowish brown (10YR 5/6) redox features in M-SP-1 and grayish brown (2.5Y 5/2) sandy loam from 4 to 11 inches with yellow red (5YR 4/6) redox features in M-SP-2. The soil within Markley Wetland 1 has a depleted matrix (F3), which satisfies the hydric soil criterion. 3.2.1.3 Markley Wetland 1 Hydrology The soils in Markley Wetland 1 were damp at the time of the field investigation. Primary indicators of wetland hydrology observed in both sample plots include water stained leaves and oxidized rhizopheres along living roots. Algae crusts and sparsely vegetated concave surfaces were located within the wetland outside of the sample plots. Hydrology for Markley Wetland 1 is primarily from a high groundwater table. 3.2.1.4 Markley Wetland 1 Determination and Rating All three mandatory wetland criteria are satisfied for Markley Wetland 1. Landau Associates classified the Markley Wetland as a forested and scrub-shrub/depressional (Cowardin/HGM classification) wetland. At the time of the field investigation Markley Wetland I was damp and algae crusts, sparsely vegetative concave surfaces, and water stained leaves were observed within the wetland. Using the Ecology wetland rating form, Markley Wetland 1 is rated as a Category II wetland, scoring highest for water quality which rated a score of 24. Habitat functions were rated with a score of 23, and hydrologic functions were rated a score of 7. Category II wetlands with a moderate habitat score between 20 and 28 points with a high level of impact from land use (Zoning Designation Residential II – Medium Density Single-Family which allows development of up to eight dwelling units per acre) require a 150-ft buffer, according to the PTMC 19.05.110. A summary of Markley Wetland 1 is provided in Table 2. 3.2.1.5 Markley Wetland 2 Vegetation The Markley Wetland 2 is dominated by hydrophytic vegetation, primarily scrub-shrub and forested with emergent vegetation underneath.

Below was black (10YR 2/1) silt loam from 6 to 12 inches with dark brown (7.5YR 3/3) redox features. The soil has a redox dark surface (F6), which satisfies the hydric soil criterion. 3.2.1.7 Markley Wetland 2 Hydrology The soils in Markley Wetland 2 were damp at the time of the field investigation. Primary indicators of wetland hydrology observed in sample plot M-SP-4 include water stained leaves and oxidized rhizopheres along living roots. Hydrology for Markley Wetland 2 is primarily from a high groundwater table. 3.2.1.8 Markley Wetland 2 Determination and Rating All three mandatory wetland criteria are satisfied for Markley Wetland 2. Landau Associates classified the Markley Wetland as a forested/depressional (Cowardin/HGM classification) wetland. At the time of the field investigation Markley Wetland 2 was damp and water stained leaves were observed within the wetland area. Using the Ecology wetland rating form, Markley Wetland 2 is rated as a Category II wetland, scoring highest for water quality function which rated a score of 24. Habitat functions were rated with a score of 23, and hydrologic functions were rated a score of 7. Category II wetlands with a moderate habitat score between 20 and 28 points with a high level of impact from land use (Zoning Designation Residential II – Medium Density Single-Family which allows development of up to eight dwelling units per acre) require a 150-ft buffer, according to the PTMC 19.05.110.

The entire wetland including the Roberts site and right of way (not including lot 6 of the Roberts property) is approximately 0.88 acres (Loggy Soil and Wetland Consulting 2006). It is not shown on the National Wetlands Inventory map but is present on the City’s Environmentally Sensitive Areas map. GW-SP-1 characterizes the vegetation, hydrology, and soils of the Gunstone-White Wetland, and sampling plot GW-SP-2 describes the adjacent upland area (see Appendix C). Two small depressional areas in the 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 3-9 north half of the Gunstone-White property were investigated as potential wetlands. These depressional areas are located north of the Gunstone-White Wetland and east of the Howard Street alignment and characterized by sampling plot GW-SP-3 and GP-SP-4. These areas were identified as wetlands in 2005; however, one area only satisfies one of the three mandatory wetland criteria and the other area satisfies none of the three mandatory wetland criteria and upon this review they were determined to be upland. 3.2.2.1 Gunstone-White Wetland Vegetation The Gunstone-White Wetland is dominated by hydrophytic vegetation, primarily scrub-shrub with emergent vegetation underneath. The dominant plant species found in this wetland includes: • Crabbapple (Malus fusca, FACW) • Nootka rose (Rosa nutkana, FAC) • Slough sedge (Carex obnupta, OBL). Additional non-dominant species found in the Gunstone-White Wetland include trailing blackberry (Rubus ursinus, FACU). 3.2.2.2 Gunstone-White Wetland Soils The soil was generally duff and organic matter from 0 to 3 inches and very dark grayish brown (10YR 3/2) silt loam from 3 to 8 inches with strong brown (7.5YR 4/6) redox features. Below was yellowish brown (10YR 5/4) sandy loam from 8 to 12 inches with strong brown (7.5YR 4/6) redox features. The soil within the Gunstone-White Wetland at GW-SP-1 is characterized as a redox dark surface (F6), which satisfies the hydric soil criterion. 3.2.2.3 Gunstone-White Wetland Hydrology The soils in the Gunstone-White Wetland were dry at the time of the field investigation. Primary indicators of wetland hydrology observed in GW-SP-1 include oxidized rhizopheres along living roots. Hydrology for the Gunstone-White Wetland is primarily from a high groundwater table. 3.2.2.4 Gunstone-White Wetland Determination and Rating All three mandatory wetland criteria are satisfied for the Gunstone-White Wetland. Landau Associates classified the wetland as a scrub-shrub/depressional (Cowardin/HGM classification) wetland. At the time of the field investigation, the Gunstone-White Wetland was dry; however, sparsely vegetated concave surfaces were found within the wetland. Using the Ecology wetland rating form, the Gunstone-White Wetland is rated as a Category III wetland, scoring highest for habitat functions which rated a score of 22. Water quality functions were 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 3-10 rated with a score of 20, and hydrologic functions were rated a score of 7. Category III wetlands with a moderate habitat score between 20 and 28 points with a high level of impact from land use (i.e. residential, commercial) require a 150-ft buffer, according to the PTMC 19.05.110. A summary of the Gunstone-White Wetland is provided in Table 2. 3.2.2.5 Upland Characterization The upland area adjacent to the Gunstone-White Wetland is characterized by sample plot GW- SP-2, which satisfies none of the three mandatory wetland criteria.

The soil within sample plot GW-SP-2 is composed of dark grayish brown (10YR 4/2) sandy loam from 0 to 11 inches. A summary of the typical upland area adjacent to the Gunstone-White Wetland is provided in Table 2. 3.2.2.6 Area investigations Two small depressional areas within the Gunstone-White property were identified as a wetland in 2005 based on onsite flagging. The first depressional area is characterized by sample plot GW-SP-3, which satisfies only one of the three mandatory wetland criteria, and located north of the Gunstone-White Wetland on the east side of the Howard Street alignment. The second depressional area is characterized by sample plot GW-SP-4, which satisfies none of the three mandatory wetland criteria, and is located at the northwest corner of the property on the east side of the Howard Street alignment. At the time of the field investigation these areas had no hydrology indicators. The dominant species found at sample plot GW-SP-3 includes crabapple (Malus fusca, FACW), Douglas-fir (Pseudotsuga menziesii, FACU), trailing blackberry (Rubus ursinus, FACU), and sword fern (polystichum munitum, FACU). Additional non-dominant species found in sample plot GW-SP-3 include salal (Gaultheria shallon, FACU), Himalayan blackberry (Rubus armeniacus, FACU), Indian plum (Oemleria cerasiformis, FACU), red elderberry (Sambuscus racemosa, FACU), and holly (Ilex aquifolium, FACU).

The soil was generally very dark gray (10YR 3/1) sandy loam from 0 to 5 inches. Below was dark grayish brown (10YR 4/2) sandy loam from 5 to 10 inches with strong brown (7.5YR 5/6) redox features. The soil within sample plot GW-SP-4 is characterized as very dark gray (10YR 3/1) sandy loam from 0 to 11 inches and then dark grayish brown (10YR 4/2) sandy loam with brown (10YR 4/3) redox features. 3.2.3 SUMMARY Markley Wetlands 1, 2 and 4 scored over 20 points for habitat while Markley Wetland 3 was less than 20 points. Based on discussions with Rick Mraz with the Department of Ecology, Markley Wetlands 1 and 2 provide water quality treatment since these are within 150 ft of an existing dirt road. Markley Wetland 4 is within 150 ft of a residential housing development and therefore also provides water quality treatment. The rating for all these wetlands is either Category II or high Category III. The ratings, vegetation, and minimal invasive species show these are very high quality wetlands. The Gunstone-White site wetland is also a Category III wetland that scored highest for water quality functions. All of these wetlands contain a diverse mix of vegetation, and provide habitat. Based on their respective scores, the Markley and Gunstone-White wetlands are all of a significantly higher quality than the mowed wetlands along the Howard Street project. 울 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 4-1 4.0 REGULATORY ASSESSMENT As indicated in the PTMC Section 19.05.110 section B regulated wetlands are: “…areas that are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Designated wetlands generally include swamps, marshes, bogs, and similar areas. Designated wetlands do not include those artificial wetlands intentionally created from nonwetland sites, including, but not limited to, irrigation and drainage ditches, grass-lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities, or those wetlands created after July 1, 1990, that were unintentionally created as a result of the construction of a road, street, or highway. Designated wetlands may include those artificial wetlands intentionally created from nonwetland areas to compensate for wetland impacts, including conversion of wetlands.” Because these wetlands are not artificial, they will be regulated as a critical area by the City. Based on conversations with the USACE, the Howard Street project wetlands will be regulated by USACE. However, the project qualifies as a Nationwide Permit 14 for linear transportation projects. Since the USACE will regulate these wetlands under Section 404 of the CWA, Ecology will regulate under Section 401 of the CWA. Since the Howard Street wetlands are being regulated by the USACE and Ecology, it is anticipated the Markley site and the Gunstone-White site wetlands which will be used as mitigation, will also be regulated by these agencies. Per the letter dated February 21, 2009 from Chris Byrnes with WDFW to the City of Port Townsend, an HPA is not required for the Howard Street work (WDFW 2009). These wetlands are also regulated under PTMC 19.05.110 subsection F (8) allows mitigation in the form of preservation for wetlands in combination with other forms of mitigation such as enhancement at the preservation site. The Markley and Gunstone-White properties do have high quality wetlands that are under imminent threat from development that is occurring on all sides of these sites. Additionally the Roberts wetland area which connects to the Gunstone-White wetland is also under imminent threat from development. These wetlands do support diverse vegetation, however in some of the buffer areas, that vegetation includes non-native invasive species such as holly, Himalayan Blackberry and scotch broom. Removing these invasive species from the wetland buffers would be used in combination with preservation of 2.85 acres of wetland area. The Howard Street project impacts are estimated at 0.37 acres of wetland impact. Based upon PTMC 19.05.110 subsection F (8) a. iv, using a combination of preservation and wetland enhancement the mitigation ratio should “range from 10:1 to 20:1 as determined on a case by case basis, depending on the quality of the wetland being mitigated and the quality of the 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 4-2 wetlands being preserved.” Using these calculations, the minimum mitigation ratio would be 3.7 acres of wetland preservation and enhancement. Our proposal is to preserve 2.85 acres of Category II and high functioning Category III wetlands and provide a minimum of 0.85 acres of buffer enhancement by removing non-native invasive species within the wetland buffers of these preserved wetlands. This provides a 10:1 mitigation ratio and preserves wetlands of a much higher quality than those being impacted. If a 12:1 ratio is required, the proposal will preserve 2.85 acres of wetlands and provide 1.59 acres of enhancement. The following is a comparison of the wetlands proposed for preservation and wetlands impacted by the Howard Street Project: Wetland Classification (Cowardin/HGM) Category Size (SF) 1 Score for Water Quality Functions Score for Hydrologic Functions Score for Habitat Functions Total Score for Functions Preservation Wetlands Markley Wetland 1 PFO-PSS/ Depression Cat II 47,369 24 7 23 54 Markley Wetland 2 PFO/ Depression Cat II 29,340 24 7 23 54 Markley Wetland 3 PFO-PEM/ Depression Cat III 2,951 12 7 18 37 Markley Wetland 4 PFO-PSS/ Depression Cat II 6,148 24 7 22 53 Gunstone -White Wetland PSS/ Depression Cat III 8,455 20 7 22 49 Impacted Wetlands Wetland A PFO/ Depression Cat III 12,697 18 5 13 36 Wetland C PEM/ Depression Cat IV 1,130 16 7 5 28 Wetland E PEM/ Depression Cat IV not regulat ed 16 7 6 29 Wetland I PSS/ Depression Cat IV 462 14 5 8 27 Wetland J PFO-PSS/ Depression Cat III 222 14 5 11 30 Wetland N PFO/ Depression Cat IV 740 14 5 10 29 Wetland O PEM/ Depression Cat IV not regulat ed 10 10 9 29 1 Impacted wetland SF for impacted area only⤉ 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 5-1 5.0 CONCEPTUAL MITIGATION The wetlands delineated for this report could be used as mitigation for the Howard Street project to the south. Preserving these wetlands will provide mitigation for the impacts to wetlands along the Howard Street corridor. The wetlands in the Howard Street ROW are within the same drainage basin and preservation and enhancement as mitigation is allowed per PTMC 19.05.110 subsection F.8.a. The Markley and Gunstone-White wetlands and the surrounding area also provide passive recreation. During the field work, it was evident these areas are used extensively for walking and bicycling. The Markley site is adjacent to existing City Open Space and preserving these wetlands will add open space and maintains recreational benefits to the local community. Therefore, the wetlands in this delineation report could be preserved and enhanced fulfilling the mitigation requirements. Per the PTMC the preservation and enhancement ratio ranges from 1:10 up to 1:20 and is determined on a case-by-case basis, depending on the quality of the wetlands being mitigated and the quality of the wetlands being preserved. Based on the scores, the wetlands on the Markley and Gunstone-White/Roberts properties all rated as Category II or very high Category III wetlands and are of a higher quality than the mowed wetlands impacted by the construction on the Howard Street project. The Markley and Gunstone-White/Roberts wetlands support a diverse native plant population, provide snags for habitat, and provide excellent opportunity to increase the existing open space and maintain existing recreation for residents and visitors to Port Townsend. As stated this is the second of a series of reports. The next report will provide full mitigation details, provided the City and the owners of the properties discussed in this report can work together to ensure preservation of these high quality wetlands. l 3/4/10 Y:\974\002\R\Markley Delineation Final_Rpt.doc LANDAU ASSOCIATES 6-1 6.0 USE OF THIS REPORT The findings presented herein are based on our understanding of City of Port Townsend Municipal Code, the USACE and Ecology wetland delineation methodology, and on our interpretation of the vegetative, soil, and hydrology conditions observed during the field investigation.

Dominance: The dominant plants and their wetland indicator status are evaluated quantitatively within data plots and visually throughout the study area. If the test for dominance fails, and indicators of wetland soils and hydrology are present, the Prevalence Index is calculated. 2. Prevalence Index: A weighted average of the percent cover of each indicator status is calculated (see data sheets in appendix). An index of 3 or less is considered meeting the hydrophytic vegetation criterion. If the Prevalence Index is not met, the consideration is given to morphological adaptations and/or non-vascular plants. Wetland Vegetation (a) Wetland vegetation is adapted to saturated soil conditions. The U.S. Fish and Wildlife Service has assigned a wetland indicator to each plant species that denotes its frequency of occurrence within wetlands. These are:  Obligate (OBL) wetland plants occur almost always in wetlands under natural conditions (more than 99 percent of the time).  Facultative wetland (FACW) plants usually occur in wetlands (67 to 99 percent of the time) but are occasionally found in nonwetlands.  Facultative (FAC) plants are equally likely to occur in wetlands or nonwetlands (34 to 66 percent of the time).  Facultative upland (FACU) plants usually occur in nonwetlands, but are occasionally found in wetlands (1 to 33 percent of the time).  Obligate upland (UPL) plans almost always occur in uplands (more than 99 percent of the time). Modifiers: + Frequency toward the higher end of the category (more frequently found in wetlands). – Frequency toward the lower end of the category (less frequently found in wetlands). * Tentative assignment based on limited information from which to determine the indicator status. More than 50% of the dominant plants totaled from all vegetation strata are hyrdrophytic, i.e. those species with indicators of OBL, FACW, or FAC (regardless of modifier), or; a plant community has a visually estimated cover percentage of OBL and FACW species that exceeds the coverage of FACU and UPL species. If dominance is not met, the Prevalence Index is calculated, or consideration is given to morphological adaptations and/or non-vascular plants observed. 3. Morphological Adaptations/Non-vascular Plants: Some plants develop recognizable morphological adaptations when occurring in wetland areas. These features must be observed on >50% of the individuals of a FACU species living in an area where indicators of hydric soils and wetland hydrology are present. Wetland non-vascular plants can include bryophytes (mosses, liverworts, hormworts). The cover of wetland bryophytes must be >50% of the total bryophyte cover in a plot in coastal Washington forested wetlands. Wetland Soils (b) Soils are classified as hydric, or they possess characteristics that are associated with reducing soil conditions. A hydric soil is formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part of the soil. Hydric soils have an identifiable color pattern, which occurs if the soil is saturated, flooded, or ponded for a long period of time. Faint or washed-out colors typically form in the soil, and redox features of bright color, such as rust (known as redoxymorphic features), form. Accumulations of organic matter at the surface, a sulfur odor, and organic matter stains may also be present. A shovel is used to dig holes at least 20 inches BGS at multiple locations in the study area. Direct observation of the soil is made at multiple locations in both wetlands and uplands, as applicable. Soil organic content is determined visually and texturally, and soil color is determined using the Munsell soil color chart (Greytag Macbeth 1994). Depth to water saturation and/or inundation is also observed (see Wetland Hydrology). The characteristics observed are compared to the hydric soil indicators for “all soils,” “sandy soils,” and “loamy clayey soils,” as described in the USACE Interim Regional Supplement (USACE 2008). Wetland Hydrology (c) The area is inundated either permanently or periodically at mean water depths less than or equal to 6.6 ft, or The soil is inundated or saturated to the surface for at least 14 consecutive days during the growing season (d). Examples of primary indicators of wetland hydrology include, but are not limited to, surface inundation (standing water), saturated soils, water marks, drift and sediment deposits, algal mat or crust, iron deposits, surface soil cracks, oxidized root channels, and presence of reduced iron. Secondary indicators of hydrology include, but are not limited to, water-stained leaves, drainage patterns, dry- season water table, geomorphic position, and the FAC-Neutral test. In the absence of any primary indicators, at least two secondary indicators are required to meet the wetland hydrology criterion. During investigation of soils, soil pits are allowed to stand up to 20 minutes in order to allow percolation of any groundwater into the pit to determine groundwater level in the soil profile. Additional digging may occur to 24 inches BGS during the dry season to investigate groundwater levels. In addition, the extent of soil saturation and presence/absence of oxidation are determined in the soils removed as part of the soils investigation (see Wetland Soils). Other indicators of wetland hydrology are observed at ground surface. Notes: (a) Categories were originally developed and defined by the USFWS National Wetlands Inventory and subsequently modified by the National Plant List Panel (Reed 1993, Reed 1988). (b) USACE 1987, 2008. (c) USACE 1987, 2008. (d) The growing season is the time during which two or more non-evergreen vascular plant species growing in a wetland or surrounding area exhibit biological activity, such as new growth. Growing season can also be determined by soil temperature. 2/25/10 Y:\974\002\R\Wetland Delineation_tb1.doc LANDAU ASSOCIATES Page 1 of 1 TABLE 2 WETLAND DELINEATION SUMMARY System Classification (Cowardin/HGM) City of Port Townsend Category Buffer Width (ft) Markley Wetland 1 PFO-PSS/Depression Cat II 150 Markley Wetland 2 PFO/Depression Cat II 150 Markley Wetland 3 PFO-PEM/Depression Cat III 80 Markley Wetland 4 PFO-PSS/Depression Cat II 150 Gunstone-White Wetland PSS/Depression Cat III 150 Key: PFO = Palustrine Forested PSS = Palustrine Scrub-Shrub PEM = Palustrine Emergent 2/25/10 Y:\974\002\R\Wetland Delineation_tb2.doc LANDAU ASSOCIATES⥪ Page 1 of 2 TABLE 3 SUMMARY OF CHARACTERISTICS OF WETLANDS AND UPLANDS SUMMARY OF MARKLEY WETLAND 1 Wetland Classification Palustrine forested/scrub-shrub (Cowardin) Depressional (HGM) Approximate Size of Wetland Within study area: 1.08 acres Hydrology Indicator(s) Water stained leaves, oxidized rhizopheres along living roots, algae crusts (in wetland area outside sample plots) Hydric Soils?

Yes X No Date of training: 6/18/08 SEC: 9 TWNSHP: 30N RNGE: 01W Is S/T/R in Appendix D? Yes_____ No X Map of wetland unit: Estimated size: Total area including past delineation: 50,468.14 sf (1.16 acre) SUMMARY OF RATING Category based on FUNCTIONS provided by wetland: I II III X IV Category I = Score > 70 Score for Water Quality Functions 20 Category II = Score 51 - 69 Score for Hydrologic Functions 7 Category III = Score 30 – 50 Score for Habitat Functions 22 Category IV = Score < 30 TOTAL Score for Functions 49 Category based on SPECIAL CHARACTERISTCS of Wetland I II Does not apply Final Category (choose the “highest” category from above”) III Summary of basic information about the wetland unit. Wetland Unit has Special Characteristics Wetland HGM Class used for Rating Estuarine Depressional X Natural Heritage Wetland Riverine Bog Lake-fringe Mature Forest Slope Old Growth Forest Flats Coastal Lagoon Freshwater Tidal Interdunal None of the above Check if unit has multiple HGM classes present Does the wetland being rated meet any of the criteria below? If you answer YES to any of the questions below you will need to protect the wetland according to the regulations regarding the special characteristics found in the wetland. Check List for Wetlands that Need Additional Protection (in addition to the protection recommended for its category) YES NO SP1. Has the wetland unit been documented as a habitat for any Federally listed Threatened or Endangered animal or plant species (T/E species)? For the purposes of this rating system, “documented” means the wetland is on the appropriate state or federal database. X SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, “documented” means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are categorized as Category 1 Natural Heritage Wetlands (see p. 19 of data form). X SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? X SP4. Does the wetland unit have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. X Gunstone-White Wetland Wetland Rating Form – western Washington, version 2 (7/06) Page 2 of 9 Classification of Vegetated Wetlands for Western Washington If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)? NO – go to 2 YES – the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES – Freshwater Tidal Fringe NO – Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term “Estuarine” wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. _____ ). 2. The entire wetland unit is flat and precipitation is 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 meet both of the following criteria? ______ The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) where at least 20 acres (8ha) in size; ______ At least 30% of the open water area is deeper than 6.6 (2 m)? NO – go to 4 YES – The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the entire wetland meet all of the following criteria? ______ The wetland is on a slope (slope can be very gradual). ______ The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. ______ The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot deep). NO – go to 5 YES – The wetland class is Slope 5. Does the entire wetland 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 two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding.. NO – go to 6 YES – The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if present is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland 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 your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the 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 Depressional Depressional + Lake-fringe Depressional Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE under wetlands with special characteristics If you are unable still to determine which of the above criteria apply to your wetland, or you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

(100m) of the wetland? NOTE: the connections do not have to be relatively undisturbed. These are DFW definitions. Check with your local DFW biologist if there are any questions. Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres) Cliffs: Greater than 7.6m (25 ft) high and occurring below 5000 ft. Old-growth 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 20 trees/ha (8 trees/acre) > 81cm (32 in) dbh or > 200 years of age. X Mature forests: Stands with average diameters exceeding 53cm (21 in) 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. Prairies: Relatively undisturbed areas (as indicated by dominance of native plants) where greases and/or forbs form the natural climax plant community. Talus: Homogenous areas of rock rubble ranging in average size 0.15 – 2.0m (0.5 – 6.5 ft), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Caves: A naturally occurring cavity, recess, void, or system of interconnected passages. Oregon white Oak: Woodlands stands of pure oak or oak/conifer associations where canopy coverage of the oak component of the stand is 25%.

Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi-enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean-derived salts measure less than 0.5 ppt. during the period of average annual low flow. Includes both estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion control).

(see p.86) Does the wetland unit meet the following criteria for Estuarine wetlands? The dominant water regime is tidal, Vegetated, and With a salinity greater than 0.5 ppt. YES = Go to SC 1.1 NO X SC 1.1 Is the wetland unit within a National Wildlife Refuge, National Park, National Estuary Reserve, Natural Area Preserve, State Park or Educational, Environmental, or Scientific Reserve designated under WAC 332-30-151? YES = Category I NO = go to SC 1.2 Cat. 1 SC 1.2 Is the wetland at least 1 acre in size and meets at least two of the following conditions? YES = Category I NO = Category II ___ The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing, and has less than 10% cover of non-native plant species. If the non-native Spartina spp,. are only species that cover more than 10% of the wetland, then the wetland should be given a dual rating (I/II). The area of Spartina would be rated a Category II while the relatively undisturbed upper marsh with native species would be a Category 1. Do not, however, exclude the area of Spartina in determining the size threshold of 1 acre. ___ At least 3/4 of the landward edge of the wetland has a 100 ft. buffer of shrub, forest, or un-grazed or un-mowed grassland ___ The wetland has at least 2 of the following features: tidal channels, depressions with open water, or contiguous freshwater wetlands. Cat. I Cat. II Dual Rating I/II SC2 Natural Heritage Wetlands (see p. 87) Natural Heritage wetlands have been identified by the Washington Natural Heritage Program/DNR as either high quality undisturbed wetlands or wetlands that support state Threatened, Endangered, or Sensitive plant species. SC 2.1 Is the wetland being rated in a Section/Township/Range that contains a natural heritage wetland? (This question is used to screen out most sites before you need to contact WNHP/DNR.)

YES = Category 1 NO X not a Heritage Wetland Cat I SC3 Bogs (see p. 87) Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation in bogs? Use the key below to identify if the wetland is a bog. If you answer yes you will still need to rate the wetland based on its function. 1. Does the unit have organic soil horizons (i.e. layers of organic soil), either peats or mucks, that compose 16 inches or more of the first 32 inches of soil profile? (See Appendix B for a field key to identify organic soils)? YES = go to question 3 NO = go to question 2 2. Does the wetland have organic soils, either peats or mucks that are less than 16 inches deep over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on a lake or pond? YES = go to question 3 NO = is not a bog for purpose of rating 3. Does the unit have more than 70% cover of mosses at ground level, AND other plants, if present, consist of the “bog” species listed in Table 3 as a significant component of the vegetation (more than 30% of the total shrub and herbaceous cover consists of species in Table 3)? YES = Is a bog for purpose of rating NO = go to question 4 NOTE: If you are uncertain about the extent of mosses in the understory you may substitute that criterion by measuring the pH of the water that seeps into a hole dug at least 16” deep. If the pH is less than 5.0 and the “bog” plant species in Table 3 are present, the wetland is a bog. 4. Is the unit forested (> 30% cover) with sitka spruce, subalpine fir, western red cedar, western hemlock, lodgepole pine, quaking aspen, Englemann’s spruce, or western white pine. WITH any of the species (or combination of species) on the bog species plant list in Table 3 as a significant component of the ground cover (> 30% coverage of the total shrub/herbaceous cover)?

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

I SC5 Wetlands in Coastal Lagoons (see p. 91) Does the wetland meet all of the following criteria of a wetland in a coastal lagoon? The wetland lies in a depression adjacent to marine waters that is wholly or partially separated from marine waters by sandbanks, gravel banks, shingle, or, less frequently, rocks. The lagoon in which the wetland is located contains surface water that is saline or brackish (> 0.5 ppt) during most of the year in at least a portion of the lagoon (needs to be measured near the bottom.) YES = Go to SC 5.1 NO X not a wetland in a coastal lagoon SC 5.1 Does the wetland meet all of the following three conditions? The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing) and has less than 20% cover of invasive plant species (see list of invasive species on p. 74).

Check List for Wetlands that Need Additional Protection (in addition to the protection recommended for its category) YES NO SP1. Has the wetland unit been documented as a habitat for any Federally listed Threatened or Endangered animal or plant species (T/E species)? For the purposes of this rating system, “documented” means the wetland is on the appropriate state or federal database. X SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, “documented” means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are categorized as Category 1 Natural Heritage Wetlands (see p. 19 of data form). X SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? X SP4. Does the wetland unit have a local significance in addition to its functions?

X ⥷ Markley Wetland 1 Wetland Rating Form – western Washington, version 2 (7/06) Page 2 of 9 Classification of Vegetated Wetlands for Western Washington If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)? NO – go to 2 YES – the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES – Freshwater Tidal Fringe NO – Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term “Estuarine” wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. _____ ). 2. The entire wetland unit is flat and precipitation is 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 meet both of the following criteria? ______ The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) where at least 20 acres (8ha) in size; ______ At least 30% of the open water area is deeper than 6.6 (2 m)? NO – go to 4 YES – The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the entire wetland meet all of the following criteria? ______ The wetland is on a slope (slope can be very gradual). ______ The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. ______ The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot deep). NO – go to 5 YES – The wetland class is Slope 5. Does the entire wetland 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 two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding.. NO – go to 6 YES – The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if present is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland 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 your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the 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 Depressional Depressional + Lake-fringe Depressional Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE under wetlands with special characteristics If you are unable still to determine which of the above criteria apply to your wetland, or you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

(100m) of the wetland? NOTE: the connections do not have to be relatively undisturbed. These are DFW definitions. Check with your local DFW biologist if there are any questions. Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres) Cliffs: Greater than 7.6m (25 ft) high and occurring below 5000 ft. Old-growth 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 20 trees/ha (8 trees/acre) > 81cm (32 in) dbh or > 200 years of age.

Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi-enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean-derived salts measure less than 0.5 ppt. during the period of average annual low flow. Includes both estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion control).

YES = Category I NO = Category II ___ The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing, and has less than 10% cover of non-native plant species. If the non-native Spartina spp,. are only species that cover more than 10% of the wetland, then the wetland should be given a dual rating (I/II). The area of Spartina would be rated a Category II while the relatively undisturbed upper marsh with native species would be a Category 1. Do not, however, exclude the area of Spartina in determining the size threshold of 1 acre. ___ At least 3/4 of the landward edge of the wetland has a 100 ft. buffer of shrub, forest, or un-grazed or un-mowed grassland ___ The wetland has at least 2 of the following features: tidal channels, depressions with open water, or contiguous freshwater wetlands.

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

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

X f Markley 02 Wetland Wetland Rating Form – western Washington, version 2 (7/06) Page 2 of 9 Classification of Vegetated Wetlands for Western Washington If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)? NO – go to 2 YES – the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES – Freshwater Tidal Fringe NO – Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term “Estuarine” wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. _____ ). 2. The entire wetland unit is flat and precipitation is 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 meet both of the following criteria? ______ The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) where at least 20 acres (8ha) in size; ______ At least 30% of the open water area is deeper than 6.6 (2 m)? NO – go to 4 YES – The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the entire wetland meet all of the following criteria? ______ The wetland is on a slope (slope can be very gradual). ______ The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. ______ The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot deep). NO – go to 5 YES – The wetland class is Slope 5. Does the entire wetland 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 two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding.. NO – go to 6 YES – The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if present is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland 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 your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the 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 Depressional Depressional + Lake-fringe Depressional Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE under wetlands with special characteristics If you are unable still to determine which of the above criteria apply to your wetland, or you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

(100m) of the wetland? NOTE: the connections do not have to be relatively undisturbed. These are DFW definitions. Check with your local DFW biologist if there are any questions. Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres) Cliffs: Greater than 7.6m (25 ft) high and occurring below 5000 ft. Old-growth 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 20 trees/ha (8 trees/acre) > 81cm (32 in) dbh or > 200 years of age.

Prairies: Relatively undisturbed areas (as indicated by dominance of native plants) where greases and/or forbs form the natural climax plant community. Talus: Homogenous areas of rock rubble ranging in average size 0.15 – 2.0m (0.5 – 6.5 ft), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Caves: A naturally occurring cavity, recess, void, or system of interconnected passages. Oregon white Oak: Woodlands stands of pure oak or oak/conifer associations where canopy coverage of the oak component of the stand is 25%. Urban Natural Open Space: A priority species resides within or is adjacent to the open space and uses it for breeding and/or regular feeding; and/or the open space functions as a corridor connecting other priority habitats, especially those that would otherwise be isolated; and/or the open space is an isolated remnant of natural habitat larger than 4 ha (10 acres) and is surrounded by urban development. Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi-enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean-derived salts measure less than 0.5 ppt. during the period of average annual low flow. Includes both estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion control).

YES = Category I NO = Category II ___ The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing, and has less than 10% cover of non-native plant species. If the non-native Spartina spp,. are only species that cover more than 10% of the wetland, then the wetland should be given a dual rating (I/II). The area of Spartina would be rated a Category II while the relatively undisturbed upper marsh with native species would be a Category 1. Do not, however, exclude the area of Spartina in determining the size threshold of 1 acre. ___ At least 3/4 of the landward edge of the wetland has a 100 ft. buffer of shrub, forest, or un-grazed or un-mowed grassland ___ The wetland has at least 2 of the following features: tidal channels, depressions with open water, or contiguous freshwater wetlands.

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

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

X Markley 03 Wetland Wetland Rating Form – western Washington, version 2 (7/06) Page 2 of 9 Classification of Vegetated Wetlands for Western Washington If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)? NO – go to 2 YES – the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES – Freshwater Tidal Fringe NO – Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term “Estuarine” wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. _____ ). 2. The entire wetland unit is flat and precipitation is 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 meet both of the following criteria? ______ The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) where at least 20 acres (8ha) in size; ______ At least 30% of the open water area is deeper than 6.6 (2 m)? NO – go to 4 YES – The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the entire wetland meet all of the following criteria? ______ The wetland is on a slope (slope can be very gradual). ______ The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. ______ The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot deep). NO – go to 5 YES – The wetland class is Slope 5. Does the entire wetland 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 two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding.. NO – go to 6 YES – The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if present is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland 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 your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the 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.

(100m) of the wetland? NOTE: the connections do not have to be relatively undisturbed. These are DFW definitions. Check with your local DFW biologist if there are any questions. Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres) Cliffs: Greater than 7.6m (25 ft) high and occurring below 5000 ft. Old-growth 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 20 trees/ha (8 trees/acre) > 81cm (32 in) dbh or > 200 years of age.

Prairies: Relatively undisturbed areas (as indicated by dominance of native plants) where greases and/or forbs form the natural climax plant community. Talus: Homogenous areas of rock rubble ranging in average size 0.15 – 2.0m (0.5 – 6.5 ft), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Caves: A naturally occurring cavity, recess, void, or system of interconnected passages.

Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi-enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean-derived salts measure less than 0.5 ppt. during the period of average annual low flow. Includes both estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion control).

If the non-native Spartina spp,. are only species that cover more than 10% of the wetland, then the wetland should be given a dual rating (I/II). The area of Spartina would be rated a Category II while the relatively undisturbed upper marsh with native species would be a Category 1. Do not, however, exclude the area of Spartina in determining the size threshold of 1 acre. ___ At least 3/4 of the landward edge of the wetland has a 100 ft. buffer of shrub, forest, or un-grazed or un-mowed grassland ___ The wetland has at least 2 of the following features: tidal channels, depressions with open water, or contiguous freshwater wetlands.

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

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

In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)? NO – go to 2 YES – the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES – Freshwater Tidal Fringe NO – Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were call estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term “Estuarine” wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. _____ ). 2. The entire wetland unit is flat and precipitation is 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 meet both of the following criteria? ______ The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) where at least 20 acres (8ha) in size; ______ At least 30% of the open water area is deeper than 6.6 (2 m)? NO – go to 4 YES – The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the entire wetland meet all of the following criteria? ______ The wetland is on a slope (slope can be very gradual). ______ The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. ______ The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot deep). NO – go to 5 YES – The wetland class is Slope 5. Does the entire wetland 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 two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding.. NO – go to 6 YES – The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if present is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland 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 your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the 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 Depressional Depressional + Lake-fringe Depressional Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE under wetlands with special characteristics If you are unable still to determine which of the above criteria apply to your wetland, or you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

(100m) of the wetland? NOTE: the connections do not have to be relatively undisturbed. These are DFW definitions. Check with your local DFW biologist if there are any questions. Riparian: The area adjacent to aquatic systems with flowing water that contains elements of both aquatic and terrestrial ecosystems which mutually influence each other. Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres) Cliffs: Greater than 7.6m (25 ft) high and occurring below 5000 ft. Old-growth 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 20 trees/ha (8 trees/acre) > 81cm (32 in) dbh or > 200 years of age. X Mature forests: Stands with average diameters exceeding 53cm (21 in) 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. Prairies: Relatively undisturbed areas (as indicated by dominance of native plants) where greases and/or forbs form the natural climax plant community. Talus: Homogenous areas of rock rubble ranging in average size 0.15 – 2.0m (0.5 – 6.5 ft), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. Caves: A naturally occurring cavity, recess, void, or system of interconnected passages. Oregon white Oak: Woodlands stands of pure oak or oak/conifer associations where canopy coverage of the oak component of the stand is 25%. Urban Natural Open Space: A priority species resides within or is adjacent to the open space and uses it for breeding and/or regular feeding; and/or the open space functions as a corridor connecting other priority habitats, especially those that would otherwise be isolated; and/or the open space is an isolated remnant of natural habitat larger than 4 ha (10 acres) and is surrounded by urban development. Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi-enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habitat extends upstream and landward to where ocean-derived salts measure less than 0.5 ppt. during the period of average annual low flow. Includes both estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components of the terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion control).

If the non-native Spartina spp,. are only species that cover more than 10% of the wetland, then the wetland should be given a dual rating (I/II). The area of Spartina would be rated a Category II while the relatively undisturbed upper marsh with native species would be a Category 1. Do not, however, exclude the area of Spartina in determining the size threshold of 1 acre. ___ At least 3/4 of the landward edge of the wetland has a 100 ft. buffer of shrub, forest, or un-grazed or un-mowed grassland ___ The wetland has at least 2 of the following features: tidal channels, depressions with open water, or contiguous freshwater wetlands.

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

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