(Shannon & Wilson) was contracted by the City of Edmonds School District (District) No. 15 to conduct a wetland and stream delineation for the New Madrona K-8 Project, located in Edmonds, Washington (Figure 1). The District plans to construct a new Madrona K-8 school on the south side of the approximately 40 -acre property, located at 9300 236th Street SW (Snohomish County tax parcel 27033600404600). The project is located within Section 36 of Township 27 N, Range 4 E, Willamette Meridian. The wetland and stream delineation is intended to assist the District and design team in the site selection and conceptual design process. The scope of services for our wetland and stream delineation was limited to the following tasks: r Conduct a background review of information relating to the site. Complete a wetland delineation on project site. Estimate approximate wetland boundaries within 200 feet of the property boundary. +� Delineate the ordinary high water mark (OHWM) of onsite streams. ■ Categorize wetlands using the 2014 Washington State Wetland Rating System for Western Washington.1 Complete a wetland delineation report describing our findings including categories and standard buffer widths. 2.0 SITE DESCRIPTION The approximately 40 -acre property is dissected by two steeply sloped wooded areas running in north -south alignments; one is a ravine located along the eastern property boundary and the other is a forested incline located near the middle of the property. The existing Madrona Elementary School is located in the northeast corner of the property and the former Woodway Elementary School is located in the opposite southwest corner of the property. Recreational areas including a track and baseball field, and soccer fields are located in the southeast and northwest corners of the property. The areas surrounding the property consist primarily of residential development. 1 The original scope also included wetland categorization under the 2004 Washington State Wetland Rating System for Western Washington, but a subsequent City critical areas regulations update rendered those forms obsolete and they are not included in this final report. 21-1-22082-002-R1flwp/1kn 21-1-22082-002 The property is well used by local residents for recreation. During our site visits, we observed many people walking dogs in trail systems located throughout the sloped wooded areas as well, as many joggers on the track. A series of catch basin grates were observed along the inside of the track. The survey performed for the property shows that these storm drains, along with storm drain from the existing Madrona Elementary School, discharge to the top of the steep wooded slope in the middle of the property. The survey also identifies storm drain discharges to the top of the wooded ravine located on the eastern property boundary. 3.0 METHODS Shannon & Wilson conducted the wetland delineation fieldwork on July 6 and 7, 2015. Potential wetlands were identified using methods described in the Corps Wetlands Delineation Manual (U.S. Army Corps of Engineers [Corps] Waterways Experiment Station, 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Corps Engineer Research and Development Center, 2010). Potential wetland areas were determined using the triple -parameter approach, which considers vegetation types, soil conditions, and hydrologic conditions. For an area to be considered wetland, it must display each of the following: (a) dominant plant species that are considered hydrophytic by the accepted classification indicators, (b) soils that are considered hydric under federal definition, and (c) indications of wetland hydrology, in accordance with the federal definition. Appendix A provides a detailed description of methodology used. Typically, the OHWM of streams are delineated following the guidance within Ecology's technical report Determining the Ordinary High Water Mark on Streams in Washington State (Ecology, 2010). However, no onsite streams were observed; therefore, no OHWM delineations occurred. Identified wetlands were delineated by using pink "wetland boundary" flagging and pink pin flags. Data point locations were marked with orange flagging and orange pin flags. 21-1-22082-002-x1f/wpnxn 21-1-22082-002 2 SANNONW11,,,,SON, TING 4.0 DOCUMENT REVIEW Prior to conducting fieldwork, we reviewed the following background information: U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (MRCS) Web Soil Survey interactive mapping system U.S. Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI) Wetlands Mapper interactive mapping system ■ Washington Department of Fish and Wildlife (WDFW) SalmonScape mapping system WDFW PHS on the Web interactive mapping system The NRCS web soil survey identifies the site soils as Alderwood gravelly, sandy loam; 15 to 30 percent slopes; Alderwood-Urban land complex; 2 to 8 percent slopes; and 8 to 15 percent slopes (USDA, 2015). These soil series are identified as non -hydric, however they may contain areas of hydric inclusions. Neither the NWI map, the WDFW SalmonScape application, nor the WDFW PHS on the Web application identify streams, wetlands, or other fish and wildlife habitat conservation areas on the property (USFWS, 2015 and WDFW, 2015 and 2.016). 5.0 WETLAND DELINEATION Three wetlands (identified as Wetland A, B, and C) were delineated in the project area (Figure 2). Descriptions of the wetland and adjoining uplands follow. Vegetation is described below by common name, with the scientific name and indicator status in parentheses for the first use. Soils are described with the associated Munsell® Color Charts color. Wetlands were characterized according to the updated 2014 version of the "Washington State Wetland Rating System for Western Washington" (Ecology, 2014) as required by the City, Corps, and Ecology (see Appendix B for Wetland Determination Data Forms and Appendix C for Wetland Rating Forms). 5.1 Wetland A Wetland A (approximately 0.02 acre) was delineated on the wooded slope located in the middle of the property, downgradient from storm drain outfalls identified on the survey. A trail system on the slope allows human and pet access to the wetland. Wetland A is classified as a palustrine scrub -shrub wetland according to the Cowardin classification and is a slope wetland according to hydrogeomorphic classification. 21-1-22082-002-R1 f/wpAkn 21-1-22082-002 SFIANNONMUSONJING Dominant vegetation in Wetland A includes a shrub strata of salmonberry (Rubus spectabilis, FAC), English laurel (Prunus laurocerasus, NI), mountain ash (Sorbus sitchensis, FAC), as well as an emergent strata of lady fern (Athyrium cyclosorum, FAC) (see Appendix B, Data Sheet DP -7). Soil in Wetland A is generally characterized by a surface horizon of black (1 OYR 2/1) loam extending to 5 inches below ground surface (bgs), underlain by a grayish brown (1 OYR 5/2) sand with dark yellowish brown (1 OYR 4/6) redoximorphic concentrations in the matrix. Soil observed in Wetland A meets the depleted below dark surface (Al 1) and depleted matrix (F3) hydric soil indicators. During the site visit, seeps were observed throughout Wetland A. Hydrology in Wetland A is likely supported by a combination of storm drain discharges from the upgradient storm drain outfalls and groundwater. Water in the data pit was observed at 11.5 inches bgs and the soil was saturated to the surface. Wetland A was rated according to Ecology's 2014 wetland rating manual (Ecology, 2014). Wetland A is rated as a Category IV wetland (Appendix Q. 5.2 Wetland B Wetland B (approximately 0.4 acre) was delineated within the wooded ravine located on the eastern property boundary. A network of walking paths run adjacent to and through parts of the wetland. Wetland B is classified as a palustrine forested wetland according to the Cowardin classification and as a depressional wetland according to the hydrogeomorphic classification. Dominant vegetation in Wetland B includes a forested strata of western red cedar (Thuja plicata, FAC) and red alder (Alnus rubra, FAC), as well as an emergent strata of slough sedge (Carex obnupta, OBL), yellow -flag iris (Iris pseudocorus, OBL), and reed canarygrass (Phalaris arundinacea, FACW) (see Appendix B, Data Sheet DP -3). Soil in Wetland B is generally characterized by a black (I OYR 2/1) silt loam extending to 4 inches bgs underlain by a very dark gray (I OYR 3/1) silt loam with gray (I OYR 6/1) depletions and dark yellowish brown (1 OYR 4/6) and grayish brown (I OYR 5/2) redoximorphic concentrations extending to 17 inches bgs, underlain by a very dark gray (I OYR 3/1) silt loam extending to 18 inches bgs, underlain by a very dark gray (I OYR 3/1) silt loam with gray (I OYR 6/1) depletions and dark yellowish brown (1 OYR 4/6) and grayish brown (I OYR 5/2) redoximorphic concentrations extending to at least 20 inches bgs. The redoximorphic and depletions observed in the soil below 4 inches bgs appeared blocky and mixed up within the 21-1-22082-002-R1 flwp/lkn 21-1-22082-002 4 SHANNON ,`3' , INC. matrix suggesting that the soil may have been disturbed in the past. Soils observed in Wetland B meet the redox dark surface (F6) hydric soil indicator. Wetland B is located downgradient of the storm drain outlets associated with the existing Madrona Elementary School and the play fields. Drainage patterns were observed upgradient of Wetland B in the ravine. While these areas showed indication of past surface water flow, they were not dominated by hydric vegetation and did not meet wetland hydric soil indicators. Hydrology in Wetland B is likely predominantly supported by surface flow from the surrounding ravine, the storm drain inputs from the school, and a seasonally high groundwater table. Wetland B was rated according to Ecology's 2014 wetland rating manual (Ecology, 2014). Wetland B is rated as a Category III wetland (Appendix Q. 5.3 Wetland C Wetland C (approximately 0.1 acre) was delineated south of Wetland A along the wooded slope located in the middle of the property, downgradient from the storm drain discharges identified on the survey. A trail system on the slope allows human and pet access to the wetland. Wetland C is classified as a palustrine emergent wetland according to the Cowardin classification and as a slope wetland according to hydrogeomorphic classification. Dominant vegetation in Wetland C includes a shrub strata of western red cedar, an emergent strata of lady fern, and creeping nightshade (Solanum dulcamara, FAC) (see Appendix B, Data Sheet DP -6). Soil in Wetland C is generally characterized by a black (1 OYR 2/1) loam, underlain by a grayish brown (1 OYR 5/2), gravelly, loamy sand with dark yellowish brown (1 OYR 4/4) redoximorphic concentrations in the matrix extending to at least 14 inches bgs. Soils observed in Wetland C meet the depleted below dark surface (A11) and the depleted matrix (F3) hydric soil indicators. During the site visit, seeps were observed throughout Wetland C. Hydrology in Wetland C is likely predominantly supported by a combination of the upgradient storm drain discharges and groundwater. Soil in the data pit was saturated to the surface. Wetland C was rated according to Ecology's 2014 wetland rating manual (Ecology, 2014). Wetland C is rated as a Category IV wetland (Appendix Q. 21-1-22082-002-R1f/wpncn 21-1-22082-002 5 SVIANNON 6WILSON, INC. 5.4 Uplands Uplands observed on the project site consist predominantly of developed school structures and recreational facilities as well as portions of the wooded slope and. The play fields are dominated by a variety of grasses, dandelion (Taraxacum officinale, facultative upland [FACU]), hairy cat's ear (Hypochaeris radicata, FACU), and clover (Trifolium repens, facultative [FAC]). The wooded areas are dominated by western red cedar, Douglas -fir (Pseudotsuga menziesii, FACU), hemlock (Tsuga heterophylla, FACU), red elderberry (Sambucus racemosa, FACU), holly (Ilex aquifolium, FACU), English laurel, sword fern (Polystichum munitum, FACU), and English ivy (Hedera helix, FACU) (see Appendix B, Data Sheets DP -1, DP -2, DP -4, and DP -5). Upland soils on the property generally consisted of a surface horizon comprised of dark yellowish brown (IOYR 3/4) to black (5YR 2.5/1) loam in the upper 2 to 5 inches bgs, underlain by dark yellowish brown (IOYR 3/4 and 4/4) to light olive brown (2.5Y 5/3) loamy sand to silt loam extending to at least 16 inches bgs. In areas closer to the wetland boundaries, redoximorphic concentrations were observed below 5 inches. However, the soil profiles in these areas do not meet wetland hydric soil indicators. No saturation was observed in the upland soils although surface drainage patterns were observed in the ravine and below storm drain outfalls on the western slope. 6.0 REGULATIONS Several local, state, and federal regulations apply to development proposals in and/or near wetlands and streams. A summary of applicable regulatory implications is given below. 6.1 Federal Regulations The Corps' review process under Section 404 of the Clean Water Act (CWA) is required for projects involving discharges of dredges or fill materials into waters of the United States, including non -isolated wetlands and streams. We did not observe a hydrologic surface connection between the onsite wetlands and a Water of the U.S. Therefore, the Corps may consider the onsite wetlands to be isolated and not subject to the CWA. However, this determination would need to be made by the Corps through a "Jurisdictional Determination." If the Corps takes jurisdiction over the site wetlands, impacts to the wetlands would require compensatory wetland mitigation. The Corps, in cooperation with Ecology, has developed guidance for conducting wetland mitigation in western Washington (Ecology and others, 2006). For unavoidable impacts to Category III and Category IV wetlands, the Corps and Ecology 21-1-22082-002-RIVwp cn 21-1-22082-002 6 ci ONSO , INC. recommend the on-site and in-kind permittee -responsible mitigation ratios shown in Table 1 based on area (area of mitigation: area of wetland impact.) TABLE 1 WETLAND IMPACT COMPENSATORY MITIGATION RATIOS 6.2 State Regulations Ecology has been authorized to implement Section 401 of the CWA for Water Quality Certification in Washington for most projects that require Corps permits under CWA Section 404. Typically, projects requiring a CWA Section 404 permit also require a CWA Section 401 Water Quality Certification. If the onsite wetlands are determined to be isolated, the project would not require a Section 401 Water Quality Certification. The purpose of the 401 certification process is to ensure that federally permitted or federally funded activities comply with the federal CWA, state water quality laws, and any other applicable state laws. Some general requirements for Section 401, if it is required, include pollution spill prevention and response measures, disposal of excavated or dredged material in upland areas, use of fill material that does not compromise water quality, clear identification of construction boundaries, and provision for site access to the permitting agency for inspection. If the Corps does not take jurisdiction over the onsite wetlands under the CWA, Ecology still has regulatory authority to protect isolated wetlands under the State Water Pollution Control Act (Chapter 90.48 Revised Code of Washington). Ecology would perform an administrative review of the project and would issue an Administrative Order for unavoidable impacts to isolated wetlands. 21-1-22082-002-R1flwp/Hm 21-1-22082-002 7 S 11 HANNON WILSON,INN a 6.3 City of Edmonds (City) 6.3.1 Wetlands Regulations The City regulates wetlands and wetland buffers under Chapter 23.50 of the Edmonds Community Development Code (ECDC) (City, 2016).2 Based on our field observations and using the 2014 Wetland Rating System for Western Washington, Wetlands A and C are Category IV wetlands and Wetland B is a Category III wetland (Appendix Q. The City requires a 60 -foot standard buffer around Category III wetlands and a 40 -foot standard buffer around Category IV wetlands, with implementation of the following minimization measures when applicable (Table 2 and Figure 2) (ECDC 23.50.040(F)(1-2)).

Accordingly, there remain some typographical errors in that version with respect to section numbering. 21-i-22082-002-R1f/wpAkn 21-1-22082-002 8 SVIA114NON 6WILSON, ING In accordance with ECDC 23.50.040(F)(2), the City may require increased buffer widths on a case-by-case basis when a larger buffer is necessary to protect wetland functions and values. The City bases this determination on the following criteria: ■ A larger buffer is needed to protect other critical areas; The buffer or adjacent uplands has a slope greater than 15 percent or is susceptible to erosion and standard erosion control measures will not prevent adverse impacts to the wetland; The buffer area has minimal vegetative cover. In lieu of increasing the buffer width where existing buffer vegetation is inadequate to protect the wetland functions and values, development and implementation of a wetland buffer enhancement plan may substitute. ■ The wetland and/or buffer is occupied by a federally listed threatened or endangered species, a bald eagle nest, a great blue heron rookery, or a species of local importance; and it is determined by the director that an increased buffer width is necessary to protect the species. ECDC 23.50.040(G) allows for buffer reduction only when existing buffer vegetation is inadequate; the buffers of the existing wetlands are primarily densely vegetated with a mix of native tree and shrub species so this provision may not be applicable. Based on our understanding of the current development proposal, there may be some small areas of existing buffer that are lawn and ballfields that would be impacted. Under ECDC 23.50(G)(3), the City allows for buffer averaging with buffer enhancement if the following requirements are met: The buffer averaging and enhancement plan provides evidence that wetland functions and values will be: Increased or retained through plan implementation for those wetlands where existing buffer vegetation is generally intact; or Increased through plan implantation for those wetlands where existing buffer vegetation is inadequate to protect the functions and values of the wetland. «� The wetland contains variations in sensitivity due to existing physical characteristics or the character of the buffer varies in slope, soils, or vegetation, and the wetland would benefit from a wider buffer in places and would not be adversely impacted by a narrower buffer in other places; ■ The total area contained in the buffer area, or the total buffer area existing on a subject parcel for wetlands extending off-site, after averaging is no less than that which would be contained within a standard buffer; and 21-1-22082-002-R1 flwp/]kn 21-1-22082-002 9 SHANNON 6WILSON,MING ■ The buffer width at any single location is not reduced by more than twenty-five percent (25%) of the standard o buffer width. However, wetland buffer averaging that also modifies the erosion hazard area and/or its buffer would not be allowed by the ECDC without a geotechnical analysis and demonstration that the wetland buffer averaging and erosion or landslide hazard area buffer modification would not adversely impact the wetlands. Wetland buffer reduction through buffer enhancement may also be allowed if buffer averaging is not feasible on site (ECDC 23.50.040(G)(4)). ECDC 23.50.040(G)(8) describes potential permitted uses within wetland buffers, including conservation and restoration activities, passive recreation (such as trails), and stormwater management facilities. The proposed development of a new school and fire access road are not allowed uses within wetland buffers. If buffer averaging or reduction with enhancement is not sufficient to address the need for placement of structures, then a variance and additional buffer mitigation would be required. 6.3.2 Other Critical Areas The City regulates critical areas including wetlands (addressed in Section 6.3.1), fish and wildlife habitat conservation areas, geologically hazardous areas, critical aquifer recharge areas, frequently flooded areas, and shorelines under ECDC Title 23 Natural Resources. Fish and wildlife habitat conservation areas include streams, state priority habitats and areas associated with state priority species, and federally designated threatened or endangered species, among others. The site investigation and document reviews did not identify any streams or other fish and wildlife habitat conservation areas on site or within 225 feet. This scope of services did not include professional assessment of other regulated critical areas. However, some observations about potential geologically hazardous areas is warranted given the affect this critical area can have on site development, particularly when it overlaps with wetlands and wetland buffers. Based on soils mapping, available topographic information, and the City's definitions of geologically hazardous areas (ECDC 23.80.020), the presence of erosion and/or landslide hazard areas on the eastern and western sides of the property at or near Wetlands A, B, and C and their buffers seems likely. A geotechnical report would be required to establish the appropriate building setback and buffer from the top and toe of any erosion or landslide hazards. An additional analysis would be required to alter the hazard area, the minimum building setback and any required buffer (ECDC 23.80.070(A)(1-2)). A hazards analysis must demonstrate the following: 21-1-22082-002-xl f/wpA m 21-1-22082-002 10 The alteration will not increase surface water discharge or sedimentation to adjacent properties beyond predevelopment conditions, M The alteration will not decrease slope stability on adjacent properties, and FA Such alterations will not adversely impact other critical areas (ECDC 23.80.070(A)(3)). Shannon & Wilson will be providing the necessary geotechnical analyses under a separate scope of work. 7.0 CLOSURE The findings and conclusions documented in this report have been prepared for specific application to this project, and have been developed in a manner consistent with that level of care and skill normally exercised by members of the environmental science profession currently practicing under similar conditions in the area, and in accordance with the terms and conditions set forth in our agreement. The conclusions and recommendations presented in this report are professional opinions based on interpretation of information currently available to us, and are made within the operational scope, budget, and schedule constraints of this project. No warranty, express or implied, is made. Shannon & Wilson has prepared Appendix D, "Important Information About Your Wetland Delineation/Mitigation and/or Stream Classification Report," to assist you and others in understanding the use and limitations of our reports.

D.. 2®12/ 21-1-22082-002 A -i APPENDIX A WETLAND DELINEATION METHODOLOGY The triple -parameter approach, as required in the Washington State Department of Ecology's (Ecology's) 1997 Washington State Wetlands Identification and Delineation Manual, the United States Army Corps of Engineers' (the Corps') 1987 Corps of Engineers Wetland Delineation Manual, and the Corps' 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) was used to identify and delineate the wetlands on the site described in this report. The triple -parameter approach requires that vegetation, soils, and hydrology are each evaluated to determine the presence or absence of wetlands. An area is considered to be a wetland if each of the following is met: (a) dominant hydrophytic vegetation is present in the area, (b) the soils in the area are hydric, and (c) the necessary hydrologic conditions within the area are met. A determination of wetland presence was made by conducting a Routine Delineation. Corresponding upland and wetland plots were recorded to characterize surface and subsurface conditions and more accurately determine the boundaries of on-site wetlands. A.1 WETLAND VEGETATION Hydrophytic plants are plant species specially adapted for saturated and/or anaerobic conditions. These species can be found in areas where there is a significant duration and frequency of inundation, which produces permanently or periodically saturated soils. Hydrophytic species, due to morphological, physiological, and reproductive adaptations, have the ability to grow, effectively compete, reproduce, and thrive in anaerobic soil. Indicators of hydrophytic vegetation are based on the wetland indicator status of plant species on the national wetland plant list (Lichvar, 2012). Plants are categorized as Obligate (OBL), Facultative Wetland (FACW), Facultative (FAC), Facultative Upland (FACU), or Upland (UPL). Species in the facultative categories (FACW, FAC, and FACU) are recognized as occurring in both wetlands and non - wetlands to varying degrees. Most wetlands are dominated mainly by species rated as OBL, FACW, or FAC (Table A-1). AppendaA Methodology (Western Mtos) Dec 2012/ A-1 21-1-22082-002 TABLE A-1 PLANT INDICATOR STATUS GROUPS Obligate Wetland (OBL) — Plants that almost always occur in wetlands. Facultative Wetland (FACW) — Plants that usually occur in wetlands, but may occur in non -wetlands. ...... .. ................. ..... _ .-......... ..... _.......—. Facultative (FAC) — Plants that occur in wetlands or non -wetlands. ...._. Facultative Upland (FACU) — Plants that usually occur in non -wetlands, but may occur in wetlands. Obligate Upland (UPL) — Plants that almost never occur in wetlands. (Lichvar, 2012) The approximate percentage of absolute cover for each of the different plant species occurring within the tree, sapling/shrub, woody vine, and herbaceous strata was determined. Trees within a 30 -foot radius; sapling/shrubs and woody vines within a 15 -foot radius; and herbaceous species within a 5 -foot radius of each data point were identified and noted. However, where site conditions merited it, the dimensions of the tree, sapling/shrub, woody vine, and herbaceous strata were modified. The dominance test is the primary hydrophytic vegetation indicator and it is used in all wetland delineations. Dominant plant species are considered to be those that, when cumulatively totaled in descending order of absolute percent cover, exceed 50 percent of the total absolute cover for each vegetative stratum. Any additional species individually representing 20 percent or greater of the total absolute cover for each vegetative strata are also considered dominant. Hydrophytic vegetation is considered to be present when greater than 50 percent of the dominant plant species within the area had an indicator status of OBL, FACW, or FAC. If a plant community does not meet the dominance test in areas where hydric soils and wetland hydrology are present, vegetation is reevaluated using the prevalence index, plant morphological adaptations for living in wetlands, and/or abundance of bryophytes (e.g., mosses) adapted to living in wetlands. The prevalence index is a weighted average that takes into account the abundance of all plant species within the sampling area to determine if hydrophytic vegetation is more or less prevalent. Using the prevalence index, all plants within the sampling area are grouped by wetland indicator status and absolute percent cover is summed for each group. Total cover for each indicator status group is weighted by the following multipliers: OBL=1, FACW=2, FAC=3, FACU=4, UPL=5. The prevalence index is calculated by dividing the sum of the weighted totals by the sum of total cover in the sampling area. A prevalence index of 3.0 or less indicates that hydrophytic vegetation is present. AppendixA_Methodology (Weste.Mtos) Dec 2012/ 21-1-22082-002 A-2 A.2 HYDRIC SOILS Hydric soils are defined as soils that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (USDA SCS, 1994). Repeated periods of saturation and inundation for more than a few days, in combination with soil microbial activity, causes depletion in oxygen (anaerobic conditions) and results in delayed decomposition of organic matter and reduction of iron, manganese, and sulfur elements. As a result of these processes, most hydric soils develop distinctive characteristics observable in the field during both wet and dry periods. (USDA NRCS, 2010). These characteristics may be exhibited as an accumulation of organic matter; bluish -gray, green -gray, or low chroma and high value soil colors; mottling or other concentrations of iron and manganese; and/or hydrogen sulfide odor similar to a rotten egg smell. The USDA Natural Resources Conservation Service (NRCS) has developed official hydric soil indicators as summarized in Field Indicators of Hydric Soils in the United States (USDA NRCS, 2010). These indicators were developed to assist in delineation of hydric soils and are based predominantly on hydric soils near the margins of wetlands. Some hydric soils, including soils within the wettest parts of wetlands, may lack any of the approved hydric soil indicators. If a hydric soil indicator is present, the soil is determined to be hydric. If no hydric soil indicator is present, additional site information is used to assess whether the soil meets the definition of hydric soil. Identification of hydric soils was aided through observation of surface hydrologic characteristics and indicators of wetland hydrology (e.g., drainage patterns). Soil characteristics were observation at several data points, placed both inside and outside the wetland. Holes were dug with a shovel to the depth needed to document an indicator or to confirm the absence of hydric soil indicators. Soil organic content was estimated visually and texturally. Soil colors were examined in the field immediately after sampling. Dry soils were moistened. Soil colors were determined through analysis of the hue, value, and chroma best represented in the Munsell® Soil Color Chart. A.3 WETLAND HYDROLOGY Wetland hydrology is determined by observable evidence that inundation or soil saturation have occurred during a significant portion of the growing season repeatedly over a period of years so that wet condition have been sufficient to produce wetland vegetation and hydric soils. Wetland hydrology indicators give evidence of a continuing wetland hydrologic regime. Wetland hydrology criteria were considered to be satisfied if it appeared that wetland hydrology was AppendixA_Methodology (Western Mtu) Dee 2012/ 21-1-22082-002. A-3 present for at least 5 to 12.5 percent (12 to 31 days) of the growing season. The growing season in western Washington is typically considered to be from March 1 to October 31 (244 days). However, the growing season is considered to have begun when: (a) evidence of plant growth has begun on two non -evergreen vascular plants, and (b) the soil reaches a temperature of 41 degrees Fahrenheit at 12 inches. The Seattle District Corps of Engineers requires 14 consecutive days of inundation or saturation for a wetland hydrology to be considered present. Wetland hydrology was evaluated by direct visual observation of surface inundation or soil saturation in data plots. The area near each data point was examined for indicators of wetland hydrology. Wetland hydrology indicators are categorized as primary or secondary based on their estimated reliability. Wetland hydrology was considered present if there was evidence of one primary indicator or at least two secondary indicators. Some primary indicators include surface water, a shallow water table or saturated soils observed within 12 inches of the surface, dried watermarks, drift lines, sediment deposits, water -stained leaves, and algal mat/crust. Some secondary indicators include a water table within 12 to 24 inches of the surface during the dry season; drainage patterns; a landscape position in a depression, drainage, or fringe of a water body; and a shallow restrictive layer capable of perching water within 12 inches of the surface.

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 S. 1. Are the water levels in the entire unit usually controlled by tides except during floods? 0- 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)? O - Saltwater Tidal Fringe (Estua�reh2ater YES - Freshwater Tidal Fringe Ifyour well as d Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO - E�can YES - The wetland class is Flats 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 anytime of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). 0 go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? X The wetland is on a slope (slope can be very gradual), X The water flows through the wetland in one direction (unidirectional) and usually comes from seeps.

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. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number A 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 sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO-goto7 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-goto8 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 HGM class to being rated use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

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 B. 1. Are the water levels in the entire unit usually controlled by tides except during floods? 0 - 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 Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. (NZO�-go�W3 YES - The wetland class is Flats 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 anytime of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). NO - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, The water leaves the wetland without being impounded. O - 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). S. 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. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number B 0 - go to 6 YES - The wetland class is Riverine Brine 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 sometime 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 wit n 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-goto8 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 HGM class to being rated use In rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than Z HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

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 ater levels in the entire unit usually controlled by tides except during floods? NO - go to 2 YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO - go to 3 YES - The wetland class is Flats aid 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 anytime of the year) at least 20 ac (8 ha) in size; _At least 30% of the open water area is deeper than 6.6 ft (2 m). NO - go to 4 YES - The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does t ie 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 occasiona y 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. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number C 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 sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO-goto7 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-goto8 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 Salt Water Tidal Fringe and any other class of freshwater wetland Riverine Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

W. APPENDIX D IMPORTANT INFORMATION ABOUT YOUR WETLAND DELINEATION/1VIITIGATION AND/OR STREAM CLASSIFICATION REPORT 21-1-22082-002 SHANNON & WILSON, INC. Attachment to and part of Report 21-1-20581-010 Geotechnical and Environmental Consultants Date: September 15, 2015 To: Ms. Taine Wilton_ Edmonds School District # ..........._-........._-..._ 15 IMPORTANT INFORMATION ABOUT YOUR WETLAND DELINEATION/MITIGATION AND/OR STREAM CLASSIFICATION DEPORT A WETLAND/STREAM REPORT IS BASED ON PROJECT -SPECIFIC FACTORS. Wetland delineation/mitigation and stream classification reports are based on a unique set of project -specific factors. These typically include the general nature of the project and property involved, its size, and its configuration; historical use and practice; the location of the project on the site and its orientation; and the level of additional risk the client assumed by virtue of limitations imposed upon the exploratory program. The jurisdiction of any particular wetland/stream is determined by the regulatory authority(s) issuing the permit(s). As a result, one or more agencies will have jurisdiction over a particular wetland or stream with sometimes confusing regulations. It is necessary to involve a consultant who understands which agency(s) has jurisdiction over a particular wetland/stream and what the agency(s) permitting requirements are for that wetland/stream. To help reduce or avoid potential costly problems, have the consultant determine how any factors or regulations (which can change subsequent to the report) may affect the recommendations. Unless your consultant indicates otherwise, your report should not be used: ► If the size or configuration of the proposed project is altered. ► If the location or orientation of the proposed project is modified. ► If there is a change of ownership. ► For application to an adjacent site. ► For construction at an adjacent site or on site. ► Following floods, earthquakes, or other acts of nature. Wetland/stream consultants cannot accept responsibility for problems that may develop if they are not consulted after factors considered in their reports have changed. Therefore, it is incumbent upon you to notify your consultant of any factors that may have changed prior to submission of our final report. Wetland boundaries identified and stream classifications made by Shannon & Wilson are considered preliminary until validated by the U.S. Army Corps of Engineers (Corps) and/or the local jurisdictional agency. Validation by the regulating agency(s) provides a certification, usually written, that the wetland boundaries verified are the boundaries that will be regulated by the agency(s) until a specified date, or until the regulations are modified, and that the stream has been properly classified. Only the regulating agency(s) can provide this certification. MOST WETLAND/STREAM "FINDINGS" ARE PROFESSIONAL ESTIMATES. Site exploration identifies wetland/stream conditions at only those points where samples are taken and when they are taken, but the physical means of obtaining data preclude the determination of precise conditions. Consequently, the information obtained is intended to be sufficiently accurate for design, but is subject to interpretation. Additionally, data derived through sampling and subsequent laboratory testing are extrapolated by the consultant who then renders an opinion about overall conditions, the likely reaction to proposed construction activity, and/or appropriate design. Even under optimal circumstances, actual conditions may differ from those thought to exist because no consultant, no matter how qualified, and no exploration program, no matter how comprehensive, can reveal what is hidden by earth, rock, and time. Nothing can be done to prevent the unanticipated, but steps can be taken to help reduce their impacts. For this reason, most experienced owners retain their consultants through the construction or wetland mitigation/stream classification stage to identify variances, to conduct additional evaluations that may be needed, and to recommend solutions to problems encountered on site. Page 1 of 2 1/2015 WETLAND/STREAM CONDITIONS CAN CHANGE. Since natural systems are dynamic systems affected by both natural processes and human activities, changes in wetland boundaries and stream conditions may be expected. Therefore, delineated wetland boundaries and stream classifications cannot remain valid for an indefinite period of time. The Corps typically recognizes the validity of wetland delineations for a period of five years after completion. Some city and county agencies recognize the validity of wetland delineations for a period of two years. If a period of years have passed since the wetland/stream report was completed, the owner is advised to have the consultant reexamine the wetland/stream to determine if the classification is still accurate. Construction operations at or adjacent to the site and natural events such as floods, earthquakes, or water fluctuations may also affect conditions and, thus, the continuing adequacy of the wetland/stream report. The consultant should be kept apprised of any such events and should be consulted to determine if additional evaluation is necessary. THE WETLAND/STREAM REPORT IS SUBJECT TO MISINTERPRETATION. Costly problems can occur when plans are developed based on misinterpretation of a wetland/stream report. To help avoid these problems, the consultant should be retained to work with other appropriate professionals to explain relevant wetland, stream, geological, and other findings, and to review the adequacy of plans and specifications relative to these issues. DATA FORMS SHOULD NOT BE SEPARATED FROM THE REPORT. Final data forms are developed by the consultant based on interpretation of field sheets (assembled by site personnel) and laboratory evaluation of field samples. Only final data forms customarily are included in a report. These data forms should not, under any circumstances, be drawn for inclusion in other drawings because drafters may commit errors or omissions in the transfer process. Although photographic reproduction eliminates this problem, it does nothing to reduce the possibility of misinterpreting the forms. When this occurs, delays, disputes, and unanticipated costs are frequently the result. To reduce the likelihood of data form misinterpretation, contractors, engineers, and planners should be given ready access to the complete report. Those who do not provide such access may proceed under the mistaken impression that simply disclaiming responsibility for the accuracy of information always insulates them from attendant liability. Providing the best available information to contractors, engineers, and planners helps prevent costly problems and the adversarial attitudes that aggravate them to a disproportionate scale. READ RESPONSIBILITY CLAUSES CLOSELY. Because a wetland delineation/stream classification is based extensively on judgment and opinion, it is far less exact than other design disciplines. This situation has resulted in wholly unwarranted claims being lodged against consultants. To help prevent this problem, consultants have developed a number of clauses for use in written transmittals. These are not exculpatory clauses designed to foist the consultant's liabilities onto someone else; rather, they are definitive clauses that identify where the consultant's responsibilities begin and end. Their use helps all parties involved recognize their individual responsibilities and take appropriate action. Some of these definitive clauses are likely to appear in your report, and you are encouraged to read them closely. Your consultant will be pleased to give full and frank answers to your questions. THERE MAY BE OTHER STEPS YOU CAN TAKE TO REDUCE RISK. Your consultant will be pleased to discuss other techniques or designs that can be employed to mitigate the risk of delays and to provide a variety of alternatives that may be beneficial to your project. Contact your consultant for further information. Page 2 oft 1/2015
