INTRODUCTION This Critical Areas Report supports environmental review of the Willows Road Culvert Replacement project. The project area is located from NE 90th Street to NE 124th Street in Redmond, Washington. This report summarizes critical areas that occur in the project area, with detailed information about wetlands and Fish and Wildlife Habitat Conservation Areas (FWHCAs), including streams. The report appendices include detailed information regarding geotechnical conditions and mapping of other critical areas (aquifer recharge and frequently flooded areas). This report also describes regulatory implications, project-related impacts, measures for avoiding or minimizing potential adverse effects, and a conceptual mitigation approach. Appendices A through F provide supplementary project information. 1.1 Project Description The City of Redmond (City) intends to rehabilitate the pavement surface on Willows Road between NE 90th Street and NE 124th Street. The existing road section will be repaved and ramps compliant with the Americans with Disabilities Act (ADA) will be upgraded. In addition, the project will replace two culverts that span Willows Road, one at Willows Creek and one at Gun Club Creek. The new culverts will generally be in the same footprint as the culverts being removed, but additional width will be provided to improve fish passage. At Willows Creek, the existing 43 by 27-inch-corrugated metal pipe (CMP) arch culvert will be replaced with a 12-foot-wide by 5-foot-high three-sided box culvert. Strip footings on each side of the culvert will be 2 feet by 2 feet and the culvert will be stabilized in place with seven 4-inch-diameter pin piles on each side of the culvert, for a total of 14 pin piles. The piles will extend 25 feet beneath the existing ground surface. At Gun Club Creek, the existing 36 by 22-inch-CMP arch culvert will be replaced with a 10-foot- wide by 4-foot-high four-sided box culvert. The culvert will be placed on an 18-inch-deep rock pad foundation. An existing water line will be expanded to 1 foot in diameter and lowered to a depth of 7 to 8 feet below surface parallel to Willows Road. The culvert replacements will be accomplished with equipment such as a pile driver, crane, excavator, dump truck, concrete truck, light service vehicles, and various hand tools. A nearby parking lot will be used for material storage and equipment staging. Access to the project site will be via existing roads. 1.2 Site Description and Investigation Areas The project is located in Redmond, Washington within the right-of-way of Willows Road, between NE 90th Street and NE 124th Street (S2 and S3, T25N, R5E and S27 and S34, T26N, R5E, Willamette Meridian) (Figure 1-1). The northern end of the project area, between NE 116th Street and NE 124th Street, is bordered by the Sammamish Valley Park and agricultural land to the east, and undeveloped forest land with some scattered development (residential and commercial structures) to the west. The central portion of the project area, between NE 100th Court and NE 116th Street, is bordered by the Willows Run Golf Course and a church parking lot to the east, and commercial/office buildings and associated parking areas to the west, with some scattered patches of undeveloped forest land. The southern end of the project area, between NE 90th Street and NE 100th Court, is surrounded by commercial/office buildings and associated parking areas. Topography is relatively flat along the entire project corridor. ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond 1-2 August 2018 │ 553-2577-018 The project is located within the Sammamish River, Willows Creek, and Peters Creek watersheds, as described in the City’s Watershed Management Plan (Herrera 2013). These watersheds are located within Water Resource Inventory Area 8 (Lake Washington/Cedar/Sammamish Watershed). The wetland and stream field investigation was limited to areas within approximately 100 feet of each end of the Willows Creek and Gun Club Creek culverts on Willows Road (see Figure 1-1). The remainder of project activities will be conducted within the existing road fill prism and will not affect critical areas. In this report, project area refers to the entire project area (the portion of Willows Road extending from NE 90th Street to NE 124th Street). Investigation areas refers to the wetland and stream field assessment areas (as described in the paragraph above). ---PAGE BREAK--- NE 90th St 132nd Ave NE 148th Ave NE NE 109th St Avondale Rd NE NE Redmond Rd 160th Ave NE 172nd Ave NE 162nd Ave NE NE 124th Way NE Novelty Hill Rd 179th Ave NE NE 112th St NE 116th St 154th Pl NE 166th Ave NE NE 104th St NE 124th St NE 116th St Willows Rd NE U V 202 0 0.25 0.5 0.125 Mile Service Layer Credits: Sources: Esri, DeLorme, NAVTEQ, USGS, Intermap, iPC, NRCAN, Esri Japan, METI, Esri China (Hong Kong), Esri (Thailand), TomTom, 2013 Source: Esri, DigitalGlobe, GeoEye, Geographics, CNES/Airbus DS, USDA, USGS, AeroGRID, IGN, and the GIS User I Date: 3/1/2018 Path: U:\PSO\Projects\Clients\2577-TetraTech\553-2577-018 Project Corridor Stream Wetland and Stream Field Investigation Area Parametrix Figure 1-1.

METHODS This critical areas investigation reviewed conditions within the project area, and included field data collection within the wetland and stream field investigation areas (as defined in Section 1.2). The sections below describe the methods for assessing wetlands, FWHCAs (including streams), critical aquifer recharge areas, geologically hazardous areas, and frequently flooded areas. The wetland and stream analyses are based on data obtained through a review of existing information and during field investigations. The goal of these efforts was to document existing information that reflects current site conditions and to collect new information necessary to assess streams and wetland boundaries. Critical aquifer recharge areas and frequently flooded areas were evaluated through analysis of existing mapping. Geologically hazardous areas were evaluated through an analysis of existing mapping and data, along with subsurface soil and groundwater investigations. 2.1 Wetland Identification and Delineation Wetland assessments were based on a review of existing information on previously mapped wetlands and soil mapping, followed by field assessment and delineation. The methods for these assessment steps are described in the sections below. 2.1.1 Existing Information Review Prior to conducting the wetland field assessment, project biologists reviewed the following maps and materials: • King County iMap database (King County 2017) • U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory online interactive mapper (USFWS 2017) • Priority Habitats and Species (PHS) data from the Washington State Department of Fish and Wildlife (WDFW 2017a) • City of Redmond wetland inventory map (Redmond 2005a) • Natural Resources Conservation Service (NRCS) Web soil survey (NRCS 2017) • Washington State Department of Natural Resources (DNR) Natural Heritage Program (DNR 2017) 2.1.2 Field Assessment Project biologists used the methods specified in the Corps of Engineers Wetland Delineation Manual (Environmental Laboratory 1987) and the indicators described in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Corps 2010) to delineate on-site wetlands. The “routine on-site determination method” was used to determine the wetland boundaries. The routine method is used for areas equal to or less than 5 acres, or for larger areas with relatively homogeneous vegetative, soil, and hydrologic properties. Wetlands are defined as those 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 ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond 2-2 August 2018 │ 553-2577-018 prevalence of vegetation typically adapted for life in saturated soil conditions. An area must meet these three criteria or exhibit at least one positive field indicator of wetland vegetation, soils, and hydrology to be considered a wetland. Wetland determination data forms from the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Corps 2010) were recorded for each wetland. The delineated wetland boundaries and sample plot locations were instrument-surveyed by professional land surveyors. The wetland field assessment evaluated vegetation, soils, and hydrologic conditions. Each of these parameters is described in the following subsections. 2.1.2.1 Vegetation During the field investigations by project biologists, dominant plant species were observed and recorded on data forms for each sample plot. The dominant plants and their wetland indicator status were evaluated to determine whether the vegetation was hydrophytic. Hydrophytic vegetation is generally defined as vegetation adapted to prolonged saturated soil conditions. To meet the hydrophytic vegetation criterion, typically more than 50 percent of the dominant plants must be Facultative, Facultative Wetland, or Obligate, based on the plant indicator status category assigned to each plant species by the USFWS (Lichvar et al. 2016). Scientific and common plant names follow currently accepted nomenclature. Most names are consistent with Flora of the Pacific Northwest (Hitchcock and Cronquist 1973), Plants of the Pacific Northwest Coast (Pojar and MacKinnon 1994), and the PLANTS Database (U.S. Department of Agriculture [USDA] 2017). 2.1.2.2 Soils Generally, an area must have hydric soils to be regulated as a wetland. Hydric soil forms when soils are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper layer. Biological activities in saturated soil result in reduced oxygen concentrations that cause a preponderance of organisms using anaerobic processes for metabolism. Over time, anaerobic biological processes result in accumulation of organic soil peat) and/or certain mineral soil color patterns, which are used as field indicators of hydric soils. Soils were examined by excavating sample plots to a depth of at least 16 inches, where feasible, to observe soil profiles, colors, and textures. Munsell® color charts (Munsell Color 2010) were used to describe soil colors. 2.1.2.3 Hydrology The investigation areas were examined for evidence of hydrology. An area is considered to have wetland hydrology when soils are ponded or saturated consecutively for 12.5 percent of the growing season. The growing season, with precipitation measured at the Seattle-Tacoma International Airport (Sea-Tac Airport) station, generally occurs from early February (February 8) to early December (December 10) (Snyder et al. 1973). Therefore, ponding or saturation must be present for approximately 38 consecutive days. Primary indicators of hydrology include surface inundation, sediment deposits, high water table, and saturated soils. Secondary indicators of hydrology include drainage patterns, watermarks on vegetation, and water-stained leaves. ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond August 2018 │ 553-2577-018 2-3 2.1.3 Wetland Classification, Rating, and Functional Assessment Delineated wetlands were classified according to the USFWS Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al. 1979; FGDC 2013) and the hydrogeomorphic (HGM) classification system (Brinson 1993). The Washington State Wetland Rating System for Western Washington–Revised (Hruby 2014) was used to rate and assess the functions of wetlands. The City of Redmond has adopted this rating system to classify its wetlands (Redmond Zoning Code [RZC] 21.64.030[A]). Table 2-1 summarizes the City’s rating criteria for each wetland rating criteria. The City assigns protective buffer widths based upon wetland rating category, habitat and water quality functions scores, and intensity of adjacent land use (RZC 21.64.030[B]) (see Section 4.1 for details). Table 2-1. City of Redmond Wetland Rating Criteria Category Rating Criteria Category I Category I wetlands are those wetlands that represent a unique or rare wetland type, are more sensitive to disturbance than most wetlands, are relatively undisturbed, and contain ecological attributes that are impossible to replace within a human lifetime, or provide a high level of functions. All wetlands with one or more of the following criteria shall be considered a Category I wetland: a) wetlands that are identified by scientists of the Washington Natural Heritage Program/DNR as high- quality, relatively undisturbed wetlands, or wetlands that support state-listed threatened or endangered plants; b) bogs; c) mature and old-growth forested wetlands over one acre in size; or d) wetlands that provide a very high level of functions as evidenced by a score of 23 points or more on the Western Washington Rating System form. Category II Category II wetlands are those wetlands that provide high levels of some functions which are difficult to replace. Category II wetlands meet the following criteria: a) wetlands scoring between 20 to 22 points on the Western Washington Rating System form; or b) wetlands that do not meet the criteria of Category I. Category III Category III wetlands are those wetlands that provide a moderate level of functions. They are typically more disturbed and have less diversity or are more isolated from other natural resources in the landscape. Category III wetlands meet the following criteria: a) wetlands scoring between 16 to 19 points on the Western Washington Rating System form; or b) wetlands that do not meet the criteria of Category I. Category IV Category IV wetlands are those wetlands that provide the lowest level of function. These wetlands score less than 16 points on the Western Washington Rating System form. 2.2 Stream Identification and Delineation Stream assessments were based on a review of existing information on previously identified streams and fish use, followed by a field assessment and ordinary high water mark (OHWM) delineation. The methods for these assessment steps are described in the sections below. 2.2.1 Existing Information Review Prior to conducting the stream field assessment, project biologists reviewed the following maps and materials: • King County iMap database (King County 2017) • PHS data from WDFW (WDFW 2017a) ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond 2-4 August 2018 │ 553-2577-018 • WDFW SalmonScape database (WDFW 2017b) • City of Redmond stream classification map (Redmond 2016a) • City of Redmond Watershed Management Plan (Herrera 2013) • Biological Assessment for the Redmond Central Connector Phase II project (Otak 2015) • Gun Club Creek fish trap data (Redmond 2017) • Willows Creek fish removal data (Taylor Associates, Inc. 2006) 2.2.2 Field Assessment Project biologists conducted a field study of the investigation areas to evaluate features that meet stream criteria. A stream is defined by the City of Redmond (RZC 21.78) as: Those areas where surface waters produce a defined channel or bed. A defined channel or bed is an area which demonstrates clear evidence of the passage of water and includes, but is not limited to, bedrock, channels, gravel beds, sand and silt beds, and defined-channel swales. The channel or bed need not contain water year-round. This definition is not meant to include artificially created irrigation ditches, canals, storm, or surface water runoff devices or other entirely artificial watercourses unless they are used by salmonid or created for the purposes of stream mitigation. The OHWM was determined and delineated for all streams in the investigation areas using methods developed by the Washington State Department of Ecology (Ecology) (Stockdale et al. 2016). The OHWM flags were instrument-surveyed by professional land surveyors. 2.2.3 Stream Classification Streams were classified according to RZC 21.64.020(A)(2)(d). Table 2-2 summarizes the City classification criteria for each stream class. The City assigned protective buffer widths based upon stream classification (RZC 21.64.020[B]) (see Section 4.2). Table 2-2. City of Redmond Stream Classification Criteria Class Classification Criteria Class I Class I streams are those streams identified as “Shorelines of the State” under the City of Redmond Shoreline Master Program. Class II Class II streams are those natural streams that are not Class I and are either perennial or intermittent and have salmonid fish use or the potential for salmonid fish use. Class III Class III streams are those natural streams that are not Class I or Class II and are either perennial or intermittent and have one of the following characteristics: a) non-salmonid fish use or the potential for non-salmonid fish use; or b) headwater streams with a surface water connection to salmon-bearing or potentially salmon-bearing streams (Class I or II). Class IV Class IV streams are those natural streams that are not Class I, Class II, or Class III. They are either perennial or intermittent, do not have fish or the potential for fish, and are non-headwater streams. ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond August 2018 │ 553-2577-018 2-5 2.3 Fish and Wildlife Habitat Conservation Areas Along with streams, the following are designated and regulated as FWHCAs under RZC 21.64.010: • Areas with which species of concern have a primary association, including:  Federally designated endangered and threatened species  State-designated endangered, threatened, and sensitive species • State priority habitats and areas associated with state priority species • Habitats and species of local importance • Naturally occurring ponds smaller than 20 acres • Waters of the State • Lakes, ponds, streams, and rivers planted with game fish by a governmental or tribal entity • Land essential for preserving connections between habitat blocks and open spaces Habitats and species were identified using the maps and materials listed in Section 2.2.1, along with the City of Redmond FWHCA map (Redmond 2005b). Observations gathered in the investigation areas during field investigations were also used to evaluate habitat conditions. 2.4 Critical Aquifer Recharge Areas Wellhead protection zones are designated and classified as critical aquifer recharge areas under RZC 21.64.050. Zones are classified as follows: • Wellhead Protection Zone 1 represents the land area overlying the 6-month time-of-travel zone of any public water source well owned by the City. • Wellhead Protection Zone 2 represents the land area that overlies the 1-year time-of-travel zone of any public water source well owned by the City, excluding the land area contained within Wellhead Protection Zone 1. • Wellhead Protection Zone 3 represents the land area that overlies the 5-year and 10-year time- of-travel zones of any public water source well owned by the City, excluding the land area contained within Wellhead Protection Zone 1 or 2. • Wellhead Protection Zone 4 represents all the remaining land area in the city not included in Wellhead Protection Zones 1, 2, or 3. Project biologists reviewed the City of Redmond wellhead protection zone map (City of Redmond 2010), which shows wellhead protection zone boundaries and classifications. 2.5 Geologically Hazardous Areas Erosion, seismic, and landslide hazard areas are designated and regulated as geologically hazardous areas under RZC 21.64.060. These areas are identified and shown in City of Redmond critical areas maps (Redmond 2005c, 2005d, and 2016b). A geologic assessment of the project area is currently being finalized (GeoEngineers 2018). ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond 2-6 August 2018 │ 553-2577-018 2.6 Frequently Flooded Areas Frequently flooded areas, which include the 100-year (1 percent annual chance) floodplain, flood fringe, floodway, and zero-rise floodway, are designated and regulated under RZC 21.64.040. These areas are identified and shown in Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps (FIRMs) (1999) and City of Redmond critical areas maps (Redmond 2005e). ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond August 2018 │ 553-2577-018 3-1 3. RESULTS The results of the background information review for critical areas and the wetland and stream field assessment are presented below. The field assessment was conducted by project biologists on November 28 and December 5, 2017. As detailed in Section 1.2, the investigation areas for the wetland and stream field assessment was limited to areas within approximately 100 feet of each end of the Willows Creek and Gun Club Creek culverts under Willows Road. Maps related to the existing information review are presented in Appendix A, and photographs of the investigation areas are included in Appendix B. 3.1 Wetland Identification and Delineation 3.1.1 Existing Information Review 3.1.1.1 Previously Mapped Wetlands National Wetlands Inventory (USFWS 2017) and PHS on the Web (WDFW 2017a) mapping identify a large emergent wetland area just east of Willows Road in the project vicinity, on the Willows Run Golf Complex and Sammamish Valley Park properties. The King County iMap (King County 2017) application does not identify any wetlands within the project vicinity. The City of Redmond wetland inventory map (Redmond 2005a) identifies a large “Mixed Wetland/Upland” area directly east of Willows Road in the project vicinity; the wetland includes and extends northward and eastward from the Willows Run Golf Complex and Sammamish Valley Park properties. The map also identifies several wetland areas located on either side of Willows Road in the project vicinity. These mapped wetlands appear to be associated with Willows Creek and other streams and drainages in the project vicinity. The DNR Natural Heritage Program does not identify any rare plants or habitats within the project area (DNR 2017). 3.1.1.2 Mapped Soils Soils along Willows Road in the southern portion of the project area (between NE 90th Street and NE 116th Street) are mapped as primarily Indianola loamy sand, with an area of Earlmont silt loam mapped near the intersection of Willows Road and NE 100th Court (NRCS 2017). In the northern portion of the project area (between NE 116th Street and NE 124th Street), soils are mapped (from south to north) as Earlmont silt loam, Alderwood gravelly sandy loam, Tukwila muck, and Earlmont sandy loam (see the soil map in Appendix The Indianola series is composed of somewhat excessively drained soils formed from glacial outwash; the Earlmont series is composed of somewhat poorly drained soils formed in floodplains from diatomaceous earth; the Alderwood series is composed of moderately well-drained soils formed from glacial drift and/or glacial outwash; and the Tukwila series is composed of very poorly drained soils formed from herbaceous organic material (NRCS 2017). Earlmont silt loam and Tukwila muck are classified as hydric. The other soil types are not classified as hydric, although hydric inclusions may be present. ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond 3-2 August 2018 │ 553-2577-018 3.1.2 Field Assessment The results of the wetland field assessment are detailed below. As stated in Section 1.2, the investigation areas for the wetland field assessment was limited to areas within approximately 100 feet of each end of the Willows Creek and Gun Club Creek culverts on Willows Road. Field investigations mapped six wetlands (Wetlands A through Attributes of the wetlands are summarized in Table 3-1. Wetlands are mapped in Figures 3-1 and 3-2.

Wetland A/Gun Club Creek receives flow from a culvert under NE 100th Court, flows northwestward, then into a culvert under the Overlake Christian Church parking lot driveway. Gun Club Creek appears to be a permanently flowing stream; the remainder of Wetland A is seasonally flooded. Indicators of wetland hydrology observed at the time of the field visit included soil saturation and a high water table at the soil surface (A1 and A2) and oxidized rhizospheres (C3). Soil was sampled at SP-1 to a depth of 16 inches and consisted of two layers. The top layer is an 8-inch-thick very dark gray (10YR 3/1) gravelly silt loam. The lower layer is a gray (5Y 5/1) clay loam with dark brown (7.5YR 3/4) and very dark gray (10YR 3/1) redoximorphic features. The soil meets the criteria for the hydric soil indicator Depleted Below Dark Surface (A11). ---PAGE BREAK--- ! ! ! !

The aquatic bed vegetation community, which is contained within the OHWM of Gun Club Creek, is dominated by watercress (Nasturtium officinale). The emergent community, which is located along the wetland fringe, consists primarily of Baltic rush (Juncus balticus) and reed canarygrass (Phalaris arundinacea). The existing vegetated buffer of Wetland A is narrow (approximately 10 feet wide) and consists primarily of mowed grass. The adjacent upland is characterized in SP-2. Wetland A is a palustrine emergent and riverine aquatic bed wetland under the USFWS system (Cowardin 1979; FGDC 2013) and a riverine wetland under the HGM system (Brinson 1993). The wetland is rated a Category III wetland according to the state and Redmond rating systems. Overall, the wetland received moderate scores for improving water quality (6 points) and hydrologic (7 points) functions because the wetland is located in an urbanized area with water quality impairments and flooding problems and is densely vegetated, but these functions are limited primarily by a periodic mowing within the wetland and lack of overbank storage potential. Wetland A scored low for habitat functions (4 points) due to low plant community type and hydroperiod diversity, lack of undisturbed connections to off-site habitat areas, and lack of special habitat features snags and undercut banks). 3.1.2.2 Wetland B Size: 0.106 acres Redmond/Ecology Rating: III Buffer: 80 feet USFWS Classification: Palustrine Emergent/Riverine Aquatic Bed HGM Classification: Riverine Sample Plots: SP-3 (wetland) and SP-4 (adjacent upland) Wetland B is a narrow, ditched wetland located south of NE 100th Court, between Willows Road and the Redmond Central Connector Trail (Figure 3-1) (Photo The northern half of the wetland is associated with Gun Club Creek, which is its primary source of hydrology. Wetland B/Gun Club Creek receives flow from a culvert under Willows Road, flows northwestward, then into a culvert under NE 100th Court that discharges into Wetland A. The primary source of hydrology to the southern portion of Wetland B is a culvert that drains a wetland (Wetland F) located on the west side of Willows Road. Gun Club Creek appears to be a permanent stream; the remainder of Wetland B contains areas that are seasonally and occasionally flooded. The primary observed indicator of wetland hydrology at the time of the field visit was saturation up to the soil surface (A3). Soil was sampled at SP-3 to a depth of 16 inches and consisted of two layers. The top layer is a 4-inch-thick very dark brown (10YR 2/2) silt loam. The lower layer is a very dark gray (10YR 3/1) loam with dark brown (7.5YR 3/4) redoximorphic features. The soil meets the criteria for the hydric soil indicator Redox Dark Surface (F6). Wetland B contains palustrine emergent and riverine aquatic bed vegetation communities. The aquatic bed vegetation community, which is contained within the OHWM of Gun Club Creek, is dominated by watercress. The emergent community, which is located along the wetland fringe and the portion of Wetland B that extends south from Gun Club Creek, consists primarily of reed canarygrass and common cattail (Typha latifolia). The existing vegetated buffer of Wetland B is narrow (approximately 10 feet wide) and consists primarily of mowed grass. Several recently planted western red cedar (Thuja plicata) and Douglas fir (Pseudotsuga menziesii) saplings are located in the buffer area west of the wetland.

Willow Creek, which flows into the wetland from the west, is the primary source of hydrology to the wetland. The water from the wetland discharges through a culvert at the northern end of the pond, east of the wetland investigation area. Indicators of wetland hydrology observed at the time of the field visit included saturation at the soil surface (A1) and a high water table (A3). Soil was sampled at SP-5 to a depth of 16 inches and consisted of two layers. The top layer is a 4-inch-thick very dark gray (2.5Y 3/1) silt loam. The lower layer is a very dark gray (2.5Y 3/1) silt loam with dark brown (7.5YR 3/4) redoximorphic features. The soil meets the criteria for the hydric soil indicator Redox Dark Surface (F6). Wetland C contains emergent and forested vegetation communities. The emergent community, which is primarily located along the northern edge of the pond, is dominated by reed canarygrass and creeping buttercup (Ranunculus repens). The forested vegetation community consists primarily of red alder (Alnus rubra) with an understory of salmonberry (Rubus spectabilis) and Himalayan blackberry (Rubus armeniacus). The buffer of Wetland C averages approximately 20 feet in width and consists of forest cover, with patches of grasses and herbaceous weeds. The adjacent upland is characterized in SP-6. Wetland C is a palustrine unconsolidated bottom, emergent, and forested wetland under the USFWS system (Cowardin et al. 1979; FGDC 2013) and a depressional wetland under the HGM system (Brinson 1993). The wetland is rated a Category III wetland according to the state and Redmond rating systems. Overall, the wetland received moderate scores for improving water quality (7 points) and hydrologic (6 points) functions because the wetland is a depressional wetland located in an urbanized area with water quality impairments and flooding problems, but these functions are limited primarily by the presence of a permanently flowing water outlet and lack of seasonally ponded areas. Wetland D also scored as moderate for habitat (6 points) functions due to the presence of multiple plant community and hydroperiod types, special habitat features snags and logs), and adjacent WDFW-designated priority habitats riparian and instream).

Wetland D drains northward and discharges directly into Willows Creek. Indicators of wetland hydrology observed at the time of the field visit included saturation at the soil surface (A3) and a high water table (A2). Soil was sampled at SP-7 to a depth of 16 inches and consists of three layers. The top layer is a 4-inch-thick very dark grayish brown (10YR 3/2) loam, and the middle layer is a 4-inch-thick very dark gray (10YR 3/1) loam. The lower layer starts at a depth of 8 inches, and is a very dark gray (10YR 3/1) loam with dark reddish brown (5YR 3/4) redoximorphic features. The soil meets the criteria for the hydric soil indicator Redox Dark Surface (F8). The northern end of Wetland D contains a palustrine forested vegetation community, which is dominated by red alder. The remainder of the wetland contains patches of palustrine scrub-shrub and emergent cover, which is dominated by Himalayan blackberry, black cottonwood (Populus balsamifera) saplings, and reed canarygrass. The buffer of Wetland A is approximately 10 feet and width, and consists primarily of mowed grasses. The adjacent upland is characterized in SP-8. Wetland D is a palustrine emergent, scrub-shrub, and forested wetland under the USFWS system (Cowardin et al. 1979; FGDC 2013) and a slope wetland under the HGM system (Brinson 1993). The wetland is rated a Category III wetland according to the state and Redmond rating systems. Overall, the wetland received moderate scores for improving water quality (7 points) and hydrologic (6 points) functions because the wetland is located in an urbanized area with water quality impairments and flooding problems and contains dense, rigid plants that can reduce the velocity of surface water flows and trap sediments. However, as a slope wetland, these functions are limited by the wetland’s limited ability to store surface flows. Wetland D scored as moderate for habitat (6 points) functions due to the presence of multiple plant community and hydroperiod types, special habitat features snags and logs), and adjacent WDFW-designated priority habitats riparian and instream).

For the purposes of this report, the focus will be on two of the streams, Willows Creek and Gun Club Creek. WDFW has identified the Gun Club Creek and Willows Creek culverts under Willows Road as partial fish barriers. The project as proposed will replace both culverts with new, larger fish-passable culverts. City of Redmond (2016a) stream mapping identifies Willows Creek as a Class II stream within the project area. Gun Club Creek is identified as a Class III stream upstream of Willows Road, and for a short distance where Willows Creek flows parallel with Willows Road of the culvert beneath Willows Road. Gun Club Creek transitions into a Class IV stream in the reach farther and outside the project area just before its confluence with the Sammamish River.1 In August 2006, fish removal and relocation activities were conducted on Willows Creek, in conjunction with the Willows Business Park Stream Daylighting Project (Taylor Associates, Inc. 2006). The project was conducted on a 500-foot section of Willows Creek, of the project area. Biologists identified several aquatic species in the creek during removal and relocation activities, including crayfish (Cambarus sp.), lamprey (Lampetra sp.), stickleback (Gasterosteus sp.), mottled sculpin (Cottus bairdii), and cutthroat trout clarkii). Fish-trapping activities were conducted within Gun Club Creek in July 2017, in conjunction with a ditch-cleaning project that was conducted immediately from the Gun Club Creek/Willows Road culvert (Redmond 2017). Aquatic species trapped include three-spined stickleback (Gasterosteus aculeatus), crayfish, sculpin (Cottus sp.) and snail (unknown genus/species). 3.2.2 Field Assessment The results of the stream field assessment are detailed below. As noted in Section 1.2, the field assessment investigation areas were limited to the areas immediately upstream and of the Gun Club Creek and Willows Creek culverts on Willows Road. Gun Club Creek and Willows Creek were the only streams observed in the investigation areas. Their attributes are described in the following sections. 3.2.2.1 Gun Club Creek Immediately upstream (west) of the project area, Gun Club Creek flows northeastward adjacent to a stormwater pond, then enters a culvert under the 9845 Willows Road office building driveway (Figure 1-1). A short section (approximately 50 feet) of open stream channel is located (northwest) of the driveway (Figure 3-1) (Photo The channel in this location is approximately 4 feet 1 RZC 21.64.020 defines Class II streams as natural streams that are not designated as Shorelines of the State, but have the potential for salmonid fish use. Class III streams are defined as natural streams that are not Shorelines of the State and have potential for non-salmonid fish use and/or are headwater streams with a surface water connection to a potentially salmonid-bearing stream. ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond August 2018 │ 553-2577-018 3-11 wide with a cobble substrate. At the time of the field assessment, flowing water (approximately 4 inches deep) was observed in the channel. Riparian vegetation in this area consists primarily of mowed grass and ornamental evergreen trees. Gun Club Creek then flows out of the culvert under Willows Road into Wetland B (Figure 3-1) (Photo The stream channel in this location is an approximately 6-foot-wide linear ditch with a silt substrate, situated between Willows Road and the Redmond Central Connector Trail. The stream flows northwestward through a culvert under NE 100th Court, through Wetland A (Photo then through another culvert under the Overlake Christian Church parking lot driveway. At the time of the field assessment, flowing water (approximately 10 inches deep) was observed in this stream reach. Riparian vegetation in this area consists primarily of emergent wetland vegetation and mowed grass (see wetland descriptions in Sections 3.1.2.1 and 3.1.2.2 for details). After flowing through the culvert under the Overlake Christian Church parking lot driveway, Gun Club Creek flows east within a linear ditch between the parking lot and the southern boundary of the Willows Run Golf Complex (Figure 1-1). The stream then flows into a culvert under the Sammamish River Trail, which outfalls directly into the Sammamish River. Under RZC 21.64.020, Gun Club Creek in the project area meets the criteria to be considered a Class III stream (see Section 4.2 for details). Class III streams receive a standard buffer of 100 feet. 3.2.2.2 Willows Creek Immediately upstream (southwest) of the project vicinity, Willows Creek flows through a forested area then enters a culvert under Willows Road (Figures 1-1 and 3-2). The stream channel upstream of the culvert is approximately 6 feet wide with a sand and very fine gravel substrate. At the time of the field assessment, flowing water (approximately 10 inches deep) was observed in the channel. Riparian vegetation in this area consists primarily of reed canarygrass, Himalayan blackberry, and red-osier dogwood, with an overstory of red alder. Wetland E drains into Willows Creek from the south, directly upstream (west) of Willows Road. Willows Creek then flows out of the culvert under Willows Road, flows through an open channel for approximately 15 feet, then flows into a recently replaced culvert under the Redmond Central Connector Trail (Figure 3-2) (Photo The stream channel in this location is approximately 10 feet wide, with a cobble and gravel substrate; the substrate was likely placed in the stream during culvert installation. At the time of the field assessment, flowing water (approximately 10 inches deep) was observed in the channel. Riparian vegetation in this area consists primarily of reed canarygrass with an overstory of red alder. Wetland D drains into Willows Creek from the south, directly (east) of Willows Road. (east) of the Redmond Central Connector Trail, Willows Creek flows approximately 20 feet then empties into a ponded area (Wetland which is a constructed stormwater facility and inline sediment trap (Figure 3-2) (Photo The pond is dominated by silt substrate, and was inundated over 2 feet deep during the field assessment.

The creek discharges to the Sammamish River through a culvert under the Sammamish River Trail, near the outlet of Gun Club Creek. ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond 3-12 August 2018 │ 553-2577-018 Under RZC 21.64.020, Willows Creek meets the criteria to be considered a Class II stream (see Section 4.2 for details). Class II streams receive a standard buffer of 150 feet, consisting of a 100-foot inner buffer and a 50-foot outer buffer. 3.3 Fish and Wildlife Habitat Conservation Areas In accordance with RZC 21.64.020, Gun Club Creek and Willows Creek are designated FWHCAs because they are “Waters of the State.” Additionally, Willows Creek provides habitat for a state priority species (coho salmon) WDFW 2017b). City mapping (Redmond 2005b) identifies several “core preservation areas” adjacent to the project area. These include a Transfer Development Rights Easement east of Willows Road and NE 116th Street, an Open Space Easement west of the Willows Road/NE 116th Street intersection, and three Native Growth Protection Easements west of Willows Road that are associated with Gun Club Creek, Willows Creek, and Peters Creek. 3.4 Critical Aquifer Recharge Areas According to City of Redmond mapping (2010), the majority of the project area is mapped as Wellhead Zone 4, with an area of Wellhead Zone 2 mapped along the east side of Willows Road immediately north of NE 90th Street. 3.5 Geologically Hazardous Areas City of Redmond mapping (Redmond 2005c, 2016b) identifies erosion and landslide hazard areas just west of the project area, near the corner of Willows Road and NE 124th Street. Nearly the entire project area, from NE 90th Street at the south to NE 116th Street, is within a mapped seismic hazard area (Redmond 2005d). The draft geological study for the project (GeoEngineers 2018) states that the project area has a moderate risk of liquefaction, because of the relatively high groundwater table and presence of loose to medium-dense alluvial deposits. The study also states that there is a low risk in seismically induced landslides due to the relative flatness of the site. See the geological study for additional details (GeoEngineers 2018). 3.6 Frequently Flooded Areas FEMA (1999) and City of Redmond (2005e) maps do not identify any frequently flooded areas within the project area. ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond August 2018 │ 553-2577-018 4-1 4. REGULATORY IMPLICATIONS Wetlands and streams within the project area are subject to federal, state, and City of Redmond regulations. At the federal level, wetlands and streams are regulated by the Clean Water Act (CWA) Section 404, which regulates placement of fill in waters of the United States. The U.S. Army Corps of Engineers (Corps) is responsible for issuing permits under Section 404 of the CWA. Activities that affect wetlands and streams may also require a water quality certification (Section 401 of the CWA), which is implemented at the state level by Ecology. Ecology reviews projects for compliance with state water quality standards and makes permitting and mitigation decisions based on the nature and extent of impacts, as well as the type and quality of wetlands or streams being affected. Activities that use, divert, obstruct, or change the flow of a water of the state, including some wetlands, typically require a Hydraulic Project Approval (HPA) permit. Washington Administrative Code (WAC) Chapter 220-110 regulates water crossing structures and describes requirements for a HPA from WDFW. The City of Redmond designates and regulates activities within critical areas and their buffers under RZC Article IV, Chapter 21.64. According to RZC 21.64.010(D) (Exceptions), only the Gun Club Creek and Willows Creek culvert replacement elements of the project are subject to Chapter 21.64. The remaining project elements are exempt (RZC 21.64.010[D][1][e]) because they involve reconstruction of an existing road and will not increase impervious area, remove flood storage capacity, or further encroach into a critical area or its buffer. City critical areas requirements applicable to the non-exempt project elements are detailed below. 4.1 Wetlands As summarized in Table 2-1, the City of Redmond uses the state wetland rating system (Hruby 2014) to classify wetlands (RZC 21.64.030[A]). Wetland buffers are determined based upon wetland category, habitat and water quality functions scores, and intensity of adjacent land use (RZC 21.64.030[B]). According to the “wetland” definition in RZC 21.78, Wetlands C, E, and F are not regulated as critical areas by the City and do not receive a protective buffer because they are constructed stormwater facilities. Ratings and required buffer widths for wetlands within the investigation areas are presented in Table 4-1. Table 4-1. Wetland Ratings and Required Buffer Widths Specified in RZC 21.64.030(B) Wetland Name Wetland Category Water Quality Function Score Habitat Function Score Buffer Width (ft)1 A III 6 4 80 B III 6 4 80 C III 7 6 N/A2 D III 7 6 150 E III 6 6 N/A2 F IV 6 4 N/A2 1 Buffers based upon a “high” intensity of adjacent land use, according to the land use intensity definitions specified in RZC 21.64.030(B)(3). 2 Wetland is a constructed stormwater facility (see as-built plans in Appendix and is not considered a regulated wetland by the City (see ‘wetland’ definition in RZC 21.78). ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond 4-2 August 2018 │ 553-2577-018 Mitigation requirements for wetland alterations are specified in RZC 21.64.030(C). Unavoidable alterations to Category II, III, and IV wetlands are allowed under certain conditions, provided that the proposed alteration and mitigation comply with RZC 21.64.030(C) and will result in no net loss of wetland functions and values. As specified in RZC 21.64.030(C)(8), where permanent wetland alterations are permitted by the City, the applicant is required to restore or create areas of wetlands in accordance with the ratios listed in RZC 21.64.030(C). The RZC does not contain specific mitigation provisions relating to temporary, construction-related impacts to wetlands and buffers. 4.2 Streams As summarized in Table 2-2, the City of Redmond classifies streams based upon several criteria, such as fish use and flow patterns (perennial or intermittent). In accordance with RZC 21.64.020(A)(2)(d), Gun Club Creek meets Class III stream criteria because it is a non-Shoreline of the State natural stream with non-salmonid fish use. Willows Creek meets Class II stream criteria because it is a non-Shoreline of the State natural stream with salmonid fish use. As specified in RZC 21.63.020(B), stream buffers are determined based upon stream class. Required buffers for streams within the investigation areas are presented in Table 4-2. Table 4-2. Stream Classifications and Required Buffer Widths according to RZC 21.64.020(B) Stream Name Stream Classification Buffer Width (ft) Gun Club Creek III 100 Willows Creek II 100 + 50 (outer buffer)1 1 Up to 35% of the total 50-foot buffer area may be cleared and graded according to RZC 21.64.020(B)(8). However, no net effective surface may be created within the outer buffer. As specified in RZC 21.64.020[D][3], culverts are allowed in Class II, III, and IV streams provided that fish passage will not be impaired, WDFW culvert design criteria are used, and the applicant keeps the culvert free of debris and sediment to allow free passage of water and fish. Proposed alterations to riparian stream corridors must meet the performance standards and mitigation requirements specified in RZC 21.64.020[F] and 21.64.020[G]. 4.3 Fish and Wildlife Habitat Conservation Areas City-regulated FWHCAs located within the investigation area vicinities include waters of the state/riparian stream corridors (Gun Club Creek and Willows Creek), areas associated with state priority species (Willows Creek), and core preservation areas (Native Growth Protection Area associated with a wetland area along Willows Creek, just west of Willows Road). Applicable City of Redmond regulations for these habitat types are detailed in Sections 4.1 and 4.2 above. 4.4 Critical Aquifer Recharge Areas Project construction activities must comply with the groundwater protection specified in RZC 21.64.050(D)(f) and The remaining critical aquifer recharge area regulations detailed in RZC 21.64.050 do not apply to the proposed project because the completed project does not involve storing, handling, treating, using, producing, recycling, or disposing of hazardous materials or other deleterious substances. ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond August 2018 │ 553-2577-018 4-3 4.5 Geologically Hazardous Areas RZC 21.64.060(E) requires submission of a geotechnical study for projects located within identified geologically hazardous areas. A geotechnical study (GeoEngineers 2018) was prepared, and will be submitted to the City under a different cover. 4.6 Frequently Flooded Areas There are no identified frequently flooded areas located within the project area; therefore, RZC 21.64.040 does not apply. ---PAGE BREAK--- ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond August 2018 │ 553-2577-018 5-1 5. IMPACT ASSESSMENT The project will not result in any permanent, adverse impacts to wetlands, FWHCAs (including streams), critical aquifer recharge areas, geologically hazardous areas, frequently flooded areas, or their buffers. Overall, the project will improve stream habitat by replacing two existing fish-barrier culverts with fish-passable structures. Culvert replacement activities will result in temporary impacts to Gun Club Creek and Willows Creek, as well as Wetlands B, D, and E (Table 5-1). Table 5-1.

Replacement of Gun Club Creek culvert will require clearing and grading activities within portions of Gun Club Creek, Wetland B, and their respective buffers (Figure 5-1). The disturbance area located at the upstream (west) end of the existing culvert consists of mowed grass and unvegetated stream channel. The disturbance area located at the (east) end of the culvert consists of mowed grass, herbaceous wetland vegetation, and partially vegetated stream channel. No tree or shrub removal is anticipated within the Gun Club Creek impact areas. Replacement of the Willows Creek culvert will require clearing and grading activities within portions of Willows Creek, Wetland D, Wetland E, and their respective buffers (Figure 5-2). The disturbance areas located at both ends of the existing culvert consist of herbaceous, shrub, and forest wetland and upland habitat, as well as unvegetated stream channel. Approximately 11 trees (primarily red alder) and several shrubs are located within the temporary impact area and will be removed. After construction, the temporarily impacted areas at both culvert replacement locations will be restored with native vegetation (see Section Some increased turbidity and minor disturbances to the stream substrate of Gun Club Creek and Willows Creek will likely occur during construction. However, impacts will be minimized by the use of erosion and sediment control best management practices (BMPs). Overall, impacts to aquatic organisms will be limited due to the short time period of construction activity and relatively minor magnitude of in-water disturbance activities and associated work (such as fish removal activities). Details on potential impacts to species listed in the Endangered Species Act and associated habitats, along with impact minimization measures, are provided in the project’s Biological Evaluation (Parametrix 2018), provided under separate cover. ---PAGE BREAK--- ---PAGE BREAK--- 0 80 160 40 Feet Service Layer Credits: Sources: Esri, DeLorme, NAVTEQ, USGS, Intermap, iPC, NRCAN, Esri Japan, METI, Esri China (Hong Kong), Esri (Thailand), TomTom, 2013 Source: Esri, DigitalGlobe, GeoEye, Geographics, CNES/Airbus DS, USDA, USGS, AeroGRID, IGN, and the GIS User I Date: 3/23/2018 Path: U:\PSO\Projects\Clients\2577-TetraTech\553-2577-018 Wetland Wetland Buffer Stream OHWM Stream Buffer Stream Stream in Culvert Combined Wetland/Stream Buffer Temporary Wetland/Stream Impacts Clearing and Grading Limits Parametrix Figure 5-1.

CONCEPTUAL MITIGATION PLAN Overall, the project will result in a net improvement to City-regulated critical areas by replacing two existing fish-barrier stream culverts with fish-passable structures. In accordance with the mitigation sequencing requirements of RZC 21.64.010(I), the project was designed to avoid permanent impacts to critical areas. Temporary impacts to wetland, stream, and buffer habitats cannot be completely avoided, but will be limited to the minimum necessary to remove and replace the Gun Club Creek and Willows Creek culverts. Following construction, all temporarily impacted wetland, riparian, and buffer habitat areas will be restored to equal or better condition. Following restoration, the sites will be monitored in accordance with the requirements of RZC 21.64.010(P). Existing unvegetated stream channel areas will be restored to pre-construction conditions, or as required by the project’s HPA. 6.1 Goals and Objectives The overall goal of the restoration plan is to replant a total of 600 square feet of temporarily impacted riparian, wetland, and buffer habitat (see planting plan in Appendix This goal will be achieved by removing any temporary fill after construction and replanting the area at a one-to-one ratio (disturbance area to restoration areas). Specific objectives to reach this goal include the following: • Increasing the cover and diversity of native trees and shrubs in the temporarily impacted riparian, wetland, and buffer habitats • Limiting invasive plant cover 6.2 Performance Criteria A set of specific performance standards has been established to correspond with the stated restoration objectives. These standards serve as benchmarks that will be used to evaluate the success of the restoration project. By monitoring the mitigation project and comparing the results to performance standards, a determination will be made as to the need for implementing a contingency plan. The performance standards are as follows: Year 1: • Planted woody species in the wetland/riparian and buffer restoration areas will achieve 100 percent survival. If all dead woody plantings are replaced, the performance measure will be met. • Invasive species such as non-native blackberry and Class B noxious weeds will occupy no more than 10 percent of the restoration areas. • Class A noxious weeds, Japanese knotweed (Polygonum cuspidatum), and knotweed hybrids will be absent after Year 1 in the restoration areas. Year 3: • Native woody cover in the wetland/riparian and buffer restoration areas will be equal to or greater than 50 percent aerial coverage. • Invasive species such as non-native blackberry and Class B noxious weeds will occupy no more than 10 percent of the restoration areas. • Class A noxious weeds, Japanese knotweed, and knotweed hybrids will be absent after Year 3 in the restoration areas. ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond 6-2 August 2018 │ 553-2577-018 Year 5: • Native woody cover in the wetland/riparian and buffer restoration areas will be equal to or greater than 80 percent aerial coverage. • Invasive species such as non-native blackberry and Class B noxious weeds will occupy no more than 10 percent of the restoration areas. • Class A noxious weeds, Japanese knotweed, and knotweed hybrids will be absent after Year 5 in the restoration areas. 6.3 Monitoring The restoration areas will be monitored over a period of no less than 5 years, in accordance with the requirements of RZC 21.64.010(P). Details for monitoring of the restoration sites are outlined below. 6.3.1 Methods The main objective of monitoring is to document the level of success in meeting the interim performance standards and the final success standards. Monitoring will be conducted by a qualified wetland and/or stream biologist and will begin the first full growing season after construction is completed and the plants have been installed. The biologist will perform a general of the site and document the percent survival. Survival of plantings will be based on comparisons with as-built drawings. Data documenting plant survival and health will be collected each time the site is monitored. Photographs will be taken to document conditions during that monitoring year. Invasive and native plant cover will be assessed using line-intercept evaluations of established transects through the site. 6.3.2 Reporting Monitoring reports will address the items presented in the preceding section, as well as document plant survival success and problems, if any. The reports will recommend plant species replacements, if necessary. Photographs will be included to document existing site conditions. In accordance with RZC 21.64.010(P)(3)(d), the Year 1 report will be produced 30 days after plantings, and two Year 2 reports will be produced (one early in the growing season and another at the end of the growing season). In Years 3 through 5, reports will be produced annually, at the end of the growing season. 6.4 Contingency Plan The City of Redmond will implement a contingency plan if the restoration areas fail to meet the stated performance criteria. Contingency plans are prepared on a case-by-case basis, depending upon the mitigation aspect that does not meet the goals and objectives of the plan. ---PAGE BREAK--- Willows Road Culvert Replacement: Critical Areas Report City of Redmond August 2018 │ 553-2577-018 7-1 7.

This report includes information that the Washington Department of Fish and Wildlife (WDFW) maintains in a central computer database. It is not an attempt to provide you with an official agency response as to the impacts of your project on fish and wildlife. This information only documents the location of fish and wildlife resources to the best of our knowledge. It is not a complete inventory and it is important to note that fish and wildlife resources may occur in areas not currently known to WDFW biologists, or in areas for which comprehensive surveys have not been conducted. Site specific surveys are frequently necesssary to rule out the presence of priority resources. Locations of fish and wildlife resources are subject to vraition caused by disturbance, changes in season and weather, and other factors. WDFW does not recommend using reports more than six months old. 01/16/2018 1.50 8 ---PAGE BREAK--- WDFW Test Map Washington Fish and Wildlife Source: Esri, DigitalGlobe, GeoEye, Geographics, CNES/Airbus PHS Report Clip Area PT LN POLY AS MAPPED SECTION QTR-TWP TOWNSHIP January 16, 2018 0 0.8 1.6 0.4 mi 0 1 2 0.5 km 1:46,368 ---PAGE BREAK--- King County, Pictometry International Corp. 2015 Date: 1/16/2018 Notes: ± The information included on this map has been compiled by King County staff from a variety of sources and is subject to change without notice.

Are the water levels in the entire unit usually controlled by tides except during floods? NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO – go to 3 YES – The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ___The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ___At least 30% of the open water area is deeper than 6.6 ft (2 NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? ____The wetland is on a slope (slope can be very gradual), ____The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, ____The water leaves the wetland without being impounded. NO – go to 5 YES – The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? ____The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, ____The overbank flooding occurs at least once every 2 years. For questions 1-7, the criteria described must apply to the entire unit being rated. If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. A X X ---PAGE BREAK--- Wetland name or number Wetland Rating System for Western WA: 2014 Update 4 Rating Form – Effective January 1, 2015 NO – go to 6 YES – The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO – go to 8 YES – The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO – go to 8 YES – The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

Are the water levels in the entire unit usually controlled by tides except during floods? NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO – go to 3 YES – The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ___The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ___At least 30% of the open water area is deeper than 6.6 ft (2 NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? ____The wetland is on a slope (slope can be very gradual), ____The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, ____The water leaves the wetland without being impounded. NO – go to 5 YES – The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? ____The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, ____The overbank flooding occurs at least once every 2 years. For questions 1-7, the criteria described must apply to the entire unit being rated. If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. D X X X ---PAGE BREAK--- Wetland name or number Wetland Rating System for Western WA: 2014 Update 4 Rating Form – Effective January 1, 2015 NO – go to 6 YES – The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO – go to 8 YES – The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Are the water levels in the entire unit usually controlled by tides except during floods? NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO – go to 3 YES – The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ___The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ___At least 30% of the open water area is deeper than 6.6 ft (2 NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? ____The wetland is on a slope (slope can be very gradual), ____The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, ____The water leaves the wetland without being impounded. NO – go to 5 YES – The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? ____The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, ____The overbank flooding occurs at least once every 2 years. For questions 1-7, the criteria described must apply to the entire unit being rated. If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO – go to 8 YES – The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

NO – go to 2 YES – the wetland class is Tidal Fringe – go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO – Saltwater Tidal Fringe (Estuarine) YES – Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO – go to 3 YES – The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ___The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ___At least 30% of the open water area is deeper than 6.6 ft (2 NO – go to 4 YES – The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? ____The wetland is on a slope (slope can be very gradual), ____The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, ____The water leaves the wetland without being impounded. NO – go to 5 YES – The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? ____The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, ____The overbank flooding occurs at least once every 2 years. For questions 1-7, the criteria described must apply to the entire unit being rated. If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO – go to 7 YES – The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO – go to 8 YES – The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

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 aggressive, opportunistic plant species (see list of species on p. 100).  At least ¾ of the landward edge of the wetland has a 100 ft buffer of shrub, forest, or un-grazed or un- mowed grassland.  The wetland is larger than 1/10 ac (4350 ft2) Yes = Category I No = Category II Cat. I Cat. II SC 6.0. Interdunal Wetlands Is the wetland west of the 1889 line (also called the Western Boundary of Upland Ownership or WBUO)? If you answer yes you will still need to rate the wetland based on its habitat functions. In practical terms that means the following geographic areas:  Long Beach Peninsula: Lands west of SR 103  Grayland-Westport: Lands west of SR 105  Ocean Shores-Copalis: Lands west of SR 115 and SR 109 Yes – Go to SC 6.1 No = not an interdunal wetland for rating SC 6.1. Is the wetland 1 ac or larger and scores an 8 or 9 for the habitat functions on the form (rates H,H,H or H,H,M for the three aspects of function)? Yes = Category I No – Go to SC 6.2 SC 6.2. Is the wetland 1 ac or larger, or is it in a mosaic of wetlands that is 1 ac or larger? Yes = Category II No – Go to SC 6.3 SC 6.3. Is the unit between 0.1 and 1 ac, or is it in a mosaic of wetlands that is between 0.1 and 1 ac? Yes = Category III No = Category IV Cat I Cat. II Cat. III Cat.
