Wetland Determination Report 1 April 26, 2020 INTRODUCTION Ecological Land Services, Inc. (ELS) was contracted by JKM Holdings, LLC to conduct a wetland determination for a property on 6th Avenue SW, King County Tax Parcel No. 3021049041, in Federal Way, Washington. This property is located within a portion of Section 30, Township 21 North, Range 4 East of the Willamette Meridian. This report summarizes the findings of the site visit conducted on April 21, 2020. During the site visit, data was collected to identify whether wetlands or other critical areas were present as outlined in the Federal Way Revised Code (FWRC) Chapter 19.145 Environmentally Critical Areas. METHODOLOGY The wetland determination followed the Routine Determination Method in the Western Mountains, Valleys, and Coast Region according to the U.S. Army Corps of Engineers, Wetland Delineation Manual (Environmental Laboratory 1987), and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys and Coast Region (Version 2.0) (USACE 2010). The Routine Determination Method examines three parameters—vegetation, soils, and hydrology— to determine if wetlands exist in a given area. Hydrology is critical in determining what is wetland but is often difficult to assess because hydrologic conditions can change periodically (hourly, daily, or seasonally). Consequently, it is necessary to determine if hydrophytic vegetation and hydric soils are present, which would indicate that water is present for long enough duration to support a wetland plant community. By definition, wetlands are those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands are regulated as “Waters of the United States” by the U.S. Arm y Corps of Engineers (USACE), as “Waters of the State” by the Washington Department of Ecology (Ecology), and locally by the City of Federal Way. To determine the presence or absence of critical areas onsite, ELS biologists collected vegetation, soils, and hydrology data at nine test plots on April 21, 2020 (Figure 2). The data showed that there were no positive indicators for any of the wetland parameters on the property and there are no critical areas offsite and within 300 feet of the property. The data collected at the nine test plots was compiled onto wetland determination data forms that are included in Appendix A. PROPERTY DESCRIPTION This 4.73-acre rectangular property is located at the intersection of 6th Avenue SW and SW 366th Street in Federal Way, Washington (Figure 1, Photoplate 1). The west side of the property is bordered by 6th Avenue SW and the northern property boundary is bordered by SW 366th Street (Photoplates 1 and 2). High density residential development surrounds this property to the west, south, and east and some lower density properties are present to the north. This property is undeveloped and composed of a mixed coniferous and deciduous forest with dense cover by shrubs, and low cover by herbaceous species (Photoplates 1 through 6). Topography onsite is undulating, but overall slopes down from west to east. No critical areas were identified onsite or within the vicinity of the property. JKM Holdings, LLC – South Campus Estates Ecological Land Services, Inc. Wetland Determination Report 2 April 26, 2020 VEGETATION The vegetation onsite consisted of mixed deciduous and coniferous upland forest dominated by big leaf maple (Acer macrophyllum, FACU) and Douglas fir (Pseudotsuga menziesii, FACU) in the canopy. There is moderate to dense coverage by shrubs species, which include oso-berry (Oemleria cerasiformis, FACU), snowberry (Symphoricarpos albus, FACU), beaked hazelnut (Corylus cornuta, FACU), English laurel (Prunus laurocerasus, FACU), Oregon grape (Mahonia nervosa, FACU), and salal (Gaultheria shallon, FACU); and sparse coverage in the herbaceous layer by sword fern (Polystichum munitum, FACU), bracken fern (Pteridium aquilinum, FACU), trailing blackberry (Rubus ursinus, FACU), and orange honeysuckle (Lonicera ciliosa, UPL). At all test plots conducted onsite, the vegetation was dominated by FACU and UPL species so the hydrophytic vegetation criterion was not met. The dominant vegetation found onsite is recorded on the attached wetland determination data forms (Appendix A). The indicator status, following the common and scientific names, indicates how likely a species is to be found in wetlands. Listed from most likely to least likely to be found in wetlands, the indicator status categories are: ▪ OBL (obligate wetland) – Almost always occur in wetlands. ▪ FACW (facultative wetland) – Usually occur in wetlands but may occur in non-wetlands. ▪ FAC (facultative) – Occur in wetlands and non-wetlands. ▪ FACU (facultative upland) – Usually occur in non-wetlands but may occur in wetlands. ▪ UPL (obligate upland) – Almost never occur in wetlands. ▪ NI (no indicator) – Status not yet determined. SOILS As referenced on the Natural Resources Conservation Service, Web Soil Survey website (NRCS 2019), Alderwood gravelly sandy loam, 0 to 8 percent slopes (AgB) is mapped across the property (Figure 3). Alderwood soils are moderately well-drained and are not hydric. Soil pits were dug at Test Plots 1 through 9 across the property to determine if the hydric soil criterion was met. Soil profiles at these locations consist of top layers of dark brown (10YR 2/2 to 10YR 3/3) silt loam to gravelly sandy loam underlain by dark brown to dark yellowish brown (10YR 3/3 to 10YR 4/4) silt loam to gravelly sandy loam. None of the soil profiles met hydric soil indicators because the soils did not meet the definition of a depleted matrix, contain redoximorphic features, or consist of organic material. HYDROLOGY There was no evidence of wetland hydrology onsite. Test Plots 1 through 9 revealed dry soils with no saturation or water table visible within 16 inches of the soil surface. No marks of ponding, drainage patterns or other indicators were present, and no streams or other critical areas were identified onsite. Therefore, the wetland hydrology criterion is not met. JKM Holdings, LLC – South Campus Estates Ecological Land Services, Inc. Wetland Determination Report 3 April 26, 2020 CRITICAL AREAS INVENTORIES National Wetlands Inventory National Wetlands Inventory (NWI) (USFWS 2020) maps no wetlands on or within 300 feet of the property (Figure 4). King County Critical Areas Map The King County Critical Areas mapping (KCCA) does not map any wetlands onsite or within 300 feet of the project area (Figure 5). The only nearby critical areas that are mapped are erosion hazard areas, but they are not mapped onsite. Priority Habitats and Species Mapping The Washington Department of Fish and Wildlife (WDFW) Priority Habitats and Species (PHS) website shows no priority habitats or species on or within 300 feet of the property (Figure 6). ELS biologists did not identify any critical areas onsite and concur with the NWI, PHS, and county maps1. NON-WETLAND DETERMINATION Data collected at Test Plots 1 through 9 revealed that no wetlands or other critical areas exist onsite. At all test plot locations, vegetation was dominated by FACU and UPL species, soils were not hydric, and no water or evidence of water was present. Additionally, no streams or drainageways were identified on or within 300 feet of the property (Appendix A, Photoplates 1 through 6). Because no critical areas exist onsite or within 300 feet of the property, the property is not encumbered by critical areas and buffers are not required onsite. LIMITATIONS ELS bases this report’s determinations on standard scientific methodology and best professional judgment. In our opinion, local, state, and federal regulatory agencies should agree with our determinations. However, the information contained in this report should be considered preliminary and used at your own risk until it has been approved in writing by the appropriate regulatory agencies. ELS is not responsible for the impacts of any changes in environmental standards, practices, or regulations after the date of this report. 1 Critical area maps are to be used with discretion because they are intended to gather general wetland information about a regional area and therefore are limited in accuracy for smaller areas due to their large scale JKM Holdings, LLC – South Campus Estates Ecological Land Services, Inc.

It is undeveloped and composed of a mixed deciduous/coniferous forest on undulating terrain. Test Plot 1 is located near the northeast property corner in a low area. This area did not meet any of the three wetland parameters so it was determined to be upland.
