The proposed project is to provide lighting for a safe walking environment and clear visibility for the applicant's employees and other persons who use the trail. There is an existing path which extends between two open water areas created for wetland mitigation associated with past development at LAP and connects LAP to the Tukwila Sounder Station. The proposed lighting would consist of approximately twenty-two 42-inch-high 10 watt LED bollards at a minimum spacing of 15 feet. The proposed lights have an approximate 180 degree light pattern, planned for the minimization of illumination in areas outside the existing path. The proposed lighting installation and construction is within a Category 2 Wetland buffer. The proposed wattage for the LED lighting along the path exceeds the maximum of what is common or regulated among other jurisdictions for wetlands conservation sites. The 10 watt LED bulbs proposed by the applicant have a varying equivalency of 75-120 watts to DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT City of, ~' r l r ()J l <{,/ PLANNING DIVISION CERTIFICATE OF EXEMPTION FROM CRITICAL AREAS REGULATIONS EVALUATION FORM & DECISION DATE: PROJECT NAME: PROJECT NUMBER: PROJECT MANAGER: OWNER/ APPLICANT: CONTACT (if other than Owner): PROJECT LOCATION: June 3, 2013 Boeing Longacres Path Lighting Critical Areas Exemption LUA13-000543, CAR Sarah Vanags, Planning Intern Boeing/ Mark Clement 737 Logan Ave N Renton, 'NA 98055 Mark Clement 737 Logan Ave N Renton, 'NA 98055 1301 S'N 16'h Street PROJECT DESCRIPTION; The applicant is requesting approval of a Critical Areas Exemption, per RMC 4-3-0SOC.S.e.iii, in order to construct and install lighting along an approximate 315 linear foot section of an existing pedestrian pathway, at Longacres Park (LAP) in the vicinity of Building 25-20, at 1301 S'N 16th Street. The proposed project is to provide lighting for a safe walking environment and clear visibility for the applicant's employees and other persons who use the trail. There is an existing path which extends between two open water areas created for wetland mitigation associated with a past development at LAP and that connects to the Tukwila Sounder Station. The proposed lighting would consist of approximately twenty-two 42-inch-high, 10 watt LED bollards at a minimum spacing of 15 feet. The proposed lights have an approximate 180 degree light pattern, planned for the minimization of illumination in areas outside the existing path. The proposed lighting installation and construction is within a Category 2 'Netland buffer. The proposed wattage for the LED lighting along the path exceeds the maximum of what is common or regulated among other jurisdictions for wetlands conservation sites. The 10 watt LED bulbs proposed by the applicant have a varying equivalency of 75-120 watts to incandescent bulbs. This level of brightness could have a negative impact on the wetland inhabitants, most especially in the areas where eight of the twenty-two lights will crossover into the buffer-wetland by 0.5 to 2 City of Renton Department of C nity & Economic Development Certificate o mption from Critical Areas Exemption Boeing Longacres Path Ughting LUA13-000543 June 3, 2013 Page 2 of 4 feet as per the applicant's mitigation report. As such, staff recommends, that the lighting be dimmed to an appropriate wattage consistent with other jurisdictions of approximate equivalency between 25 and 35 watts incandescent; in addition, staff recommends the lights be turned off following business hours and that these be conditions of approval. The proposed pathway lighting would minimize impacts to the critical areas because work will be contained within the buffer and will not impact the wetland. Applicant's proposed installation and construction will take place in already and previously disturbed areas of the buffer. Additionally, by containing illumination to 180 degrees facing the trail path wetland inhabitants will be minimally impacted by permanent effects of the lighting after installation. The applicant is also proposing the installation of a 50 feet high pole with a 40 feet high Osprey nest platform to support wildlife. The proposed pole-platform is located at the western perimeter ofthe Boeing Longacres Park, adjacent to a tall snag, currently the preferred perch ofthe Osprey, a neighborhood nest site on a cell tower located 0.19 mi northwest ofthe proposed nest pole-platform. The proposed nest pole-platform is at the west boundary of the open space at the southwest corner of the south pond. The pole the applicant is proposing to erect would be 330 feet west of the south tip of south pond and 75 feet northeast of a tree snag at the edge of an abandoned concrete roadway. The distance from the south pond to the pole work site is 238 feet. The location for the proposed pole is west of the wetland. All construction and disruption needed in order to install the nest-pole will have no negative impacts on the surrounding environment and will not take place on the adjacent Category 2 wetland conservation area. Those completing the installation will be able to directly access the construction location via an abandoned concrete road. The applicant recommends clearing volunteer cottonwood saplings and a small group of Scotch Broom shrubs to attract Osprey to the new nest-pole location. Staff reccomends that any tree removals within the wetland and buffer zones or trees greater than 6" caliper at chest height outside ofthe wetland and buffer zones require a separate Land Use Permit. CRITICAL AREA: Category 2 Wetland, Wetland Buffer EXEMPTION JUSTIFICATION: Pursuant to RMC 4-3-050C.5.e.iii, Roads, Parks, Public and Private Utilities and RMC 4-3-050C.5.g.i, Activities in Critical areas Buffers, of the Critical Areas Regulations is hereby granted: X Roads, Parks, Public and Private Utilities ii.

The existing path extends between two open water areas created for wetland mitigation associated with past development at LAP and connects LAP to the Tukwila Sounder Station. The lighting will consist of approximately twenty-two 42-inch-high IO watt LED bollards at a minimum spacing of 15 feet. The lights have an approximate 180 degree light pattern to minimize illumination of areas outside of the existing path. This report provides results of the critical areas study, including wetland delineation of the existing Boeing mitigation wetlands and characterization of habitat conservation areas; assessment of project-related impacts to wetlands, floodplain (i.e., flood hazards), wetland buffer, and habitat conservation areas; and a description of the proposed compensatory mitigation for those impacts in order to satisfy the City's critical areas regulations. Critical area impacts are avoided/minimized by the proposed project. Wetland areas are avoided by construction of the proposed project, and proposed lighting has been designed to minimize impact to adjacent wetland. Trenching will occur in disturbed areas adjacent to wetlands, and these areas will be restored following construction. Selective pruning of tree/shrubs in critical habitat may occur. Pruning will be limited to extent necessary for construction and will not have a significant impact to habitat. Proposed aboveground electrical infrastructure will be supported on metal stakes (2 inch diameter or smaller), and portions of the stakes may be below the base flood elevation of the I 00-year floodplain. The stakes would not reduce the effective storage volume in the floodplain, and no compensatory storage is proposed. All other aboveground structures associated with the proposed project are above the base flood elevation of the I 00-year floodplain. Landau Associates completed this report in support of mitigation sequencing for critical areas within the proposed project. 4/16113 \\edmda\801\projects\025\185\120\FileRm\R\Critical Areas Rp1\LAP _SounderPath Critic.al Areas_rpt docx LANDAU ASSOCIATES ii This page intentionally left blank. 4/16/13 \\edmda\a01\pro1ects\025\185\120\F1leRm\R\Cnt1cal Areas Rp1\lAP _SounderPath Cntical Areas_rpt.docx LANDAU ASSOCIATES iii MITIGATION FACT SHEET Site Information Location Wetland Impact & Mitigation Sites (same) Site Names Boeing Longacres Park Sounder Path County King City Renton Section, Township, Range Section 24, Township 23 North, Range 4 East Latitude, Longitude (GIS verified) 47.462229 N lat.I -122.236328 W long.

The existing path extends between two open water areas created for wetland mitigation (Boeing wetland mitigation) associated with past development at LAP and connects LAP to the Tukwila Sounder Station. The lighting will consist of approximately twenty-two 42-inch-high 10 watt LED bollards at a minimum spacing of 15 ft. The lights have an approximate 180 degree light pattern to minimize illumination of areas outside of the existing path. The project purpose is to increase safety for pedestrians traveling between the Sounder Station and the LAP site. Project construction will include trenching in areas of topsoil outside of the wetland boundary and trenching in existing paved areas along the path. Landau Associates conducted an investigation to assist Boeing in determining potential impacts to the Boeing mitigation wetlands, other "waters of the U.S.," and other critical areas, specifically associated buffers, floodplains, and habitat conservation areas, regulated by the City. Critical area impacts are avoided/minimized by the proposed project. Landau Associates completed this report in support of mitigation sequencing for critical areas within the proposed project. The results of Landau Associates' investigation are presented in this report, along with description of the mitigation sequence for avoiding/minimizing impacts. 1.1 SITE DESCRIPTION The project is located within the Duwamish-Green watershed [Water Resource Inventory Area (WRIA) 9] in Section 24, Township 23 North, and Range 4 East. Land use in the project vicinity is primarily commercial uses associated with LAP. The existing path is a dual use pathway that includes paved walking trail and paved vehicle access road separated by an elevated curb. An observation deck is present within the project area that overlooks the southern portion of the Boeing wetland mitigation area connecting from the path. The topography in the vicinity of the project is relatively flat. The study area consists of the areas within 300 ft of the proposed lighting alignment, including underground utilities (Figure 2). Wetland delineation was limited to accessible areas within 100 ft of the proposed project. Habitats that extend beyond the project footprint, and within 300 ft, were estimated both visually based on field observation and using public domain resources. 4/16/13 \\edmdata01\projects\025\185\120\FileRm\R\Clitical Areas Rpt\LAP _SounderPath Critical Areas_rpt.docx LANDAU ASSOCIATES 1-1 1.2 REGULATORY BACKGROUND The Clean Water Act requires authorization for the discharge of dredged or fill material into the "waters of the U.S." under Section 404. Title IV, Chapter 3 of the City of Renton Municipal Code (RMC) contains requirements for establishing wetland buffer widths and building setbacks, and requirements for any alteration including fill of wetlands and their buffers. The Washington State Department of Ecology (Ecology) requires compliance with the State Water Pollution Control Act (RCW 90.48), and it has administrative oversight of Section 401 of the Clean Water Act for water quality certification in the case of impacts to U.S. Army Corps of Engineers (USA CE) jurisdictional "waters of the U.S." Any work that will use, divert, obstruct, or change the bed or flow of state waters, including streams and rivers, must do so under the terms of Hydraulic Project Approval (HPA) issued by the Washington Department offish and Wildlife (WDFW). WDFW HPA is administered under RCW 77.55 and rules set forth in Chapter 220-110 WAC. Wetlands and certain waterways are regulated by federal, state, and local governmental agencies, and compliance with one agency does not necessarily fulfill permitting requirements of any other agencies. All delineated wetlands and/or waterways described in this report are subject to verification by the USACE. The USACE determines the jurisdiction of a wetland based on the connection, more commonly referred to as adjacency, to other "waters of the U.S." Those wetlands determined to be "isolated" do not fall under the jurisdiction of the USA CE. If delineated wetlands are determined to be adjacent rather than isolated, any filling or dredging of onsite wetlands would require compliance with Section 404 and 401 of the Clean Water Act and the Endangered Species Act. Only the USACE can make the determination if a wetland is adjacent or isolated. If the wetlands are determined to be isolated, they may still be subject to regulation by Ecology under the State Water Pollution Control Act (RCW 90.48). In addition, the City has requirements for establishing wetland buffer widths and building setbacks, as well as for any alteration, including fill, of wetlands and their buffers. Given an adequate enhancement plan, the City may allow a reduction of standard buffer widths along with averaging of buffer widths [Section 4-3-050(M)(6)(e) of the RMC]. Title IV, Chapter 3 of the RMC also contains requirements for developments in/adjacent to habitat conservation areas and flood hazard areas (i.e., floodplain). 4/16113 l\edmdata01 \proJectsl02511851120\F1leRm\R\Cnt1cal Areas Rpt\LAP _SounderPa1h Critical Areas_rpt docx LANDAU ASSOCIATES 1-2 2.0 METHODS Landau Associates conducted an information review, wetland and waterway delineation, impact assessment, and prepared a mitigation sequencing plan for impacts to critical areas associated with the proposed project according to the methods described below. 2.1 WETLAND INVESTIGATION Landau Associates conducted the wetland investigation in accordance with the USACE Welland Delinealion Manual (USA CE 1987), the USA CE Regional Guidance letter on the 1987 Manual (USA CE 1994), the USACE Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coasl Region (USACE 2010). ln general, the USACE typically recommend a preliminary data gathering and synthesis of available background information, followed by a field investigation. 2.1.1 BACKGROUND INFORMATION REVIEW Landau Associates reviewed the following public domain resources to determine existing conditions, potential wetlands/other "waters of the U.S.," and other critical areas within the study area: • Topographic map (USDA NRCS 2001; Appendix A, Figure A-1) • Aerial photograph (Bing Maps 2010; Figure 2) • National Wetlands Inventory (NW!) map (USFWS 1981 to present; Appendix A, Figure A-2) • Soil Survey Geographic database (USDA, NRCS website 2006; Appendix A, Figure A-3) • National Hydric Soils List (USDA, NRCS website 2012) • SalmonScape (WDFW 2013a) • Flood data (FEMA 1996; Appendix A, Figure A-4) • Precipitation data (USDA NRCS website 2002, National Climatic Data Center website 2013). 2.1.2 WETLAND DELINEATION The USACE outlines a three-parameter approach to determine the presence or absence of wetlands that requires evaluating vegetation, soil, and hydrology (Table 1 ). Landau Associates biologists completed the field delineation using the routine onsite method, where data are collected at locations representative of typical wetlands and/or uplands of the study area. Following this method, an area is determined to be wetland if each of the following three criteria are met (also see Table l ): • The dominant vegetation is hydrophytic. • Soils are hydric. 4/16113 l\edmdata01\projects\025\1851120\FileRm\R\Critical Areas Rpl\LAP _SounderPath Critical Areas_rpt.docx LANDAU ASSOCIATES 2-1 • Wetland hydrology is present. The wetland boundaries were delineated using numbered flagging. A Global Positioning System (GPS) device capable of submeter accuracy was used to collect locations of wetland boundary flags and sampling points. 2.2 WETLAND CLASSIFICATION, RATING, AND BUFFER WIDTH Any wetlands identified as part of this project were classified according to the U.S. Fish and Wildlife Service's (USFWS) Cowardin classification system (Cowardin et al. 1979) and the USACE's hydrogeomorphic (HGM) classification system (Brinson 1993). Wetlands were rated according to the Washington State Wetlands Rating System for Western Washington (Hruby 2004), which is accepted practice by the City. This system categorizes wetlands based on their existing functions, including water quality, hydrology, and habitat, as well as the wetland's rarity, sensitivity to disturbance, or irreplaceability. The wetland categories range from 1 to 4 (highest to lowest category). Section 4-3-0SO(M) of the RMC identifies three categories of wetland as follows: • Category 1 wetlands are those which meet one or more of the following criteria: (a) The presence of species listed by Federal or State government as endangered or threatened, or the presence of essential habitat for those species; and/or (b) Wetlands having forty percent (40%) to sixty percent (60%) permanent open water (in dispersed patches or otherwise) with two (2) or more vegetation classes; and/or (c) Wetlands equal to or greater than ten (10) acres in size and having three (3) or more vegetation classes, one of which is open water; and/or (d) The presence of plant associations of infrequent occurrence; or at the geographic limits of their occurrence. • Category 2 wetlands are those which meet one or more of the following criteria: (a) Wetlands that are not Category 1 or 3 wetlands; and/or (b) Wetlands that have heron rookeries or osprey nests, but are not Category 1 wetlands; and/or (c) Wetlands of any size located at the headwaters of a watercourse (i.e., a wetland with a perennial or seasonal outflow channel), but with no defined influent channel, but are not Category 1 wetlands; and/or (d) Wetlands having minimum existing evidence of human-related physical alteration such as diking, ditching, or channelization. • Category 3 wetlands are those which meet one or more of the following criteria: (a) Wetlands that are severely disturbed (severely disturbed wetlands are wetlands which are characterized by hydrologic isolation, human-related hydrologic alterations such as diking, ditching, channelization, and/or outlet modification; and have soils alterations such as the presence of fill, soil removal, and/or compaction of soils; and may have altered vegetation); and/or (b) Wetlands that are newly emerging (newly emerging wetlands are wetlands occurring on top of fill materials; and characterized by emergent vegetation, low plant species richness and used minimally by wildlife. These wetlands are generally found in the areas such as the Green River Valley and Black River Drainage Basin); and/or (c) All other wetlands not classified as Category 1 or 2 such as smaller, high quality wetlands. Wetland buffers were determined according to Section 4-3-050(M)(6)(c) of the RMC. Existing buffer functions were assessed in a narrative evaluation using the Wetland Mitigation in Washington State 4116113 lledmda1a01\proJectsl0251185\120\F1leRm\R\Cnt1cal Areas Rp!ILAP _SounderPath Critical Areas_rpt docx LANDAU ASSOCIATES 2-2 Part I: A Synthesis "f the Science (Ecology 2005) and best professional judgment given specific indicators. 2.3 FLOODPLAINS Section 4-3-050(1) of the RMC specifies regulations for flood hazards, which includes the 100- year floodplain identified by the Federal Emergency Management Agency (FEMA). The extent of the 100-year floodplain was determined by reviewing FEMA flood mapping, including base flood elevations in the project vicinity. The base flood elevation is the computed elevation to which floodwater is anticipated to rise during the base flood (FEMA 2013). Elevations of the project area were determined using 2 ft contour data available from the City (City of Renton 2010). Datum of the FEMA mapping was converted for consistency with City contour data using the National Geodetic Survey Orthometric Height Conversion (NOAA 2013). Project plans were overlaid on the City contour data to identify project activities between existing ground elevations and the base flood elevation. 2.4 IDENTIFICATION AND CHARACTERIZATION OF HABITAT CONSERVATION AREAS As defined in Section 4-3-0SO(K) of the RMC, habitat conservation areas include the following critical habitats: • Habitats associated with the documented presence of non-salmonid species proposed or listed by the Federal government or State of Washington as endangered, threatened, candidate, sensitive, monitor, or priority; and/or • Category l wetlands. The City requires a habitat/wildlife assessment for activities that are located within or abutting a critical habitat, or that are adjacent to a critical habitat, and have the potential to significantly impact a critical habitat. The assessment shall determine the extent, function, and value of the critical habitat and potential for impacts and mitigation. The identification of critical habitat includes wetland delineation and rating procedures detailed above, and review of the following sensitive species information: • WDFW Priority Habitats and Species (PHS) Data on the Web (WDFW 2013b) • USFWS species listings for King County (Appendix B) • DNR Natural Heritage data (DNR 2013) • Boeing/U.S. Department of Agriculture (USDA) LAP species inventory (Appendix 8). The presence of listed species was determined by comparison of Boeing species inventory data with listings maintained by USFWS and WDFW. Functions of identified critical habitat, which includes the existing wetland mitigation site, were assessed using the Washington State Wetlands Rating System 4116J13 l\edmdata01\projecis\025\185\ 120\FileRm\R\Critii:al Areas Rpt\LAP _SounderPath Critical Areas_rpt docx LANDAU ASSOCIATES 2-3 for Western Washington (Hruby 2004), as described above. The Ecology rating system considers the following in determining habitat functions: • Vegetation structure • Hydroperiods • Richness of Plant Species • Interspersion of Habitats • Special Habitat Features • Buffers • Corridors and Connections • Near or Adjacent to other Priority Habitats Listed by WDFW • Wetland Landscape. 2.5 MITIGATION SEQUENCING AND DESIGN This project was designed in accordance with City, USACE, and Ecology guidance and requirements for Mitigation Sequencing, which allow for impacts when impacts are unavoidable and necessary and where project design efforts have been made to reduce and/or minimize impacts. 2.5.1 IMPACT ASSESSMENT Estimated proposed limits of clearing and grading were overlaid on critical area boundaries using ArcGIS software. The areas of critical area were calculated using ArcGIS software. 2.5.2 MITIGATION SEQUENCE The mitigation plan was developed using the sequence provided in Title IV, Chapter 4 of the RMC, which outlines requirements for mitigation associated with alternations to wetlands, critical habitat/wildlife habitat, associated buffers, and flood hazards. The mitigation sequence generally includes avoidance, minimization of impacts, and compensation for any impacts. This mitigation sequence is consistent with guidance provided by the USACE associated with wetland/waterway impacts. Information on the mitigation sequence is discussed in Section 4.0. 4/16/13 l\edmdata01 lprojects\025\185\120\F1leRm\R\Cnt1cal Areas Rpt\LAP _SounderPath Cnllcal Areas_rpt docx LANDAU ASSOCIATES 2-4 3.0 CRITICAL AREAS INVESTIGATION RESULTS 3.1 BACKGROUND INFORMATION REVIEW Below is a summary of topographic mapping, City documentation, NW! mapping, species mapping/databases, soil survey information, and other sources documenting conditions in and adjacent to the project area. 3.1.1 WETLANDS The topographic map for the project area (USDA NRCS 200 I) does not identify wetlands or waterways in the study area (Appendix A, Figure A-I). The NW! Map (USFWS 1981 to present) does not identify any wetlands intersecting the study area (Appendix A, Figure A-2). City of Renton wetlands inventory identifies four wetlands in the study area (Appendix A, Figure A-2). Boeing has installed wetland mitigation at LAP. Portions of the Boeing mitigated wetlands intersect the study area along with other wetlands identified on the City wetland inventory. The City wetland inventory does not show the full extent of the Boeing mitigation wetlands. The mitigation wetlands consist of open water areas that drain to Springbrook Creek to the east. 3.1.2 SPECIES OCCURRENCE Fish WDFW PHS data on the web and the SalmonScape website do not identify salmon/trout within the open water areas of the mitigation wetlands (WDFW 2013a, 2013b). The outlet of the mitigation wetlands was designed to prohibit fish passage from Springbrook Creek (DeNune, D., 2013, personal communication). Other Species WDFW PHS data on the web does not identify any priority species/habitats in the study area (WDFW 2013b). The Washington Department of Natural Resources (DNR) Natural Heritage Program does not identify any rare plant species, including those listed as threatened or endangered, within the township, range, sections of the project site (DNR 2013). Species inventory of the mitigation wetlands completed by Boeing and the USDA is included in Appendix B. Those species considered as part of critical habitat pursuant to Section 4-3-050(K) of the RMC are identified in Table 2. Due, in part, to the presence of listed species, the mitigation wetlands are considered habitat conservation areas. 4/16/13 \\edmdata01\projects\025\1851120\FileRm\R\Critical Areas Rpt\LAP _S0u11derPath Crilical Areas_rpt.docx LANDAU ASSOCIATES 3-1 3.1.3 SOILS The Soil Survey Geographic Database for King County, Washington (USDA. NCRS website 2006) identifies one soil series within the study area (Appendix A, Figure A-3 ): • Urban Land (5) is soil that has been modified by disturbance of the natural layers with additions of fill material several feet thick to accommodate development (USDA NRCS 1973). Urban Land is not classified as hydric in the National Hydric Soils List (USDA, NRCS website 2012). 3.1.4 FLOODPLAIN The Q3 flood data (FEMA 1996) identifies the project area within the IOO-year floodplain of Springbrook Creek (Appendix A, Figure A-4). The base flood elevation identified by FEMA in the project vicinity is approximately 16 ft (datum in NGVD 29; Appendix C). Review of current survey information available from the City for the project area indicates the I 00-year floodplain corresponds to elevation 19.5 ft (datum in NAVO 88; Appendix C). 3.1.5 LAND USE Review of aerial photography shows the project area contains access paths associated with LAP; the mitigation wetlands, including vegetated and open water areas; helipad; and maintained lawn/landscape areas (Figure 2). 3.1.6 PRECIPITATION Precipitation data for the 3-month period prior to the field investigation in the Puget Sound Lowlands (National Climatic Data Center website 2013) indicate recorded precipitation levels were within the normal range listed in Natural Resources Conservation Service (NRCS) WETS tables (USDA, NRCS website 2002; Appendix D). However, the month previous to the field effort was drier than normal. 3.2 FIELD INVESTIGATION Landau Associates wetland ecologists Steven Quarterman and Rosemary Trimmer conducted a field investigation on March 14, 2013. The weather during the site reconnaissance was overcast. A sampling point was recorded in areas suspected to meet the mandatory wetland criteria and nearby upland to determine corresponding wetland/upland boundaries. The mitigation wetland boundaries were delineated using numbered flagging. Detailed information on soils, vegetation, and hydrology was recorded at three sampling points within wetland and upland location(s), as shown on 4116113 \\edmdata01\projecls\025\185\120\FileRm\R\Clitical Areas Rpt\LAP _SounderPalh Critical Areas_rpt docx LANDAU ASSOCIATES 3-2 Figure 3. The boundaries of one wetland (constituting two portions of the wetland mitigation area) were delineated and boundaries extending off site were estimated based on aerial photographs (Figure 3). A summary of the delineated wetlands, including classifications and buffer requirements, 1s provided in Table 2. The sampling point locations and delineated wetlands are shown on Figure 3, and the completed data sheets describing the sampling points and site photographs are provided in Appendix E and Appendix F, respectively. Wetland rating information is included in Appendix G. 3.2.1 MITIGATION WETLAND (WETLAND Wl/W2) An approximate I. I-acre portion of the nearly 18-acre wetland mitigation site at LAP is located within the project area (flags Wl-1 to Wl-24 and W2-I to W2-14). A portion of the mitigation wetland, flags W2-I to W2-14, north of the study area, is identified on the city's wetland inventory mapping (see Appendix A). Sampling Point SP-1 was recorded to characterize the vegetation, hydrology, and soils of the mitigation wetland south of the proposed project (flags Wl-1 to Wl-24), and Sampling Point SP-2 was recorded to describe the of the mitigation wetland north of the proposed project (flags W2-I to W2-14; Figure 3 and Appendix F). Sample Point SP-3 was recorded to describe adjacent upland area (Figure 3 and Appendix F). The north and south portions of the wetland are hydrologically connected and are presented as a single wetland unit for this discussion. 3.2.1.1 Vegetation Wetland WI /W2 is dominated by hydrophytic vegetation. The dominant plant species and their indicator status' at Sampling Point SP-I and SP-2 include: • Red alder (A/nus rubra, FAC) • Slough sedge (Carex obnuta, OBL) • Black cottonwood (Populus ba/samifera, F AC) • Western red cedar (Thuja plicata, FAC) • Indian plum ( Oemleria cerasiformis, FACU). Additional species found in Wetland W1/W2, but outside of the sampling points, include but are not limited to: black gooseberry (Ribes lacustre, F AC), flowering currant (Ribes sanguineum, no indicator provided), sticky currant (Ribes viscosissium, FAC), common snowberry (Symphoricarpos a/bus, F ACU), creeping buttercup (Ranuncu/us repens, FAC), reed canary grass (Phalaris arundinacea, FACW), rose spp. (Rosa spp.), vine maple (Acer circinatum, FAC), curly dock (Rumex crispus, FAC), red osier dogwood (Cornus alba, FACW), soft rush (Juncus effuses, FACW), willows (Salix spp.), cattail (Typha /atifolia, OBL), bulrush (Schoeneplectus acutus, OBL), red elderberry (Sambucus racemosa, FACU), 4J16J13 lledmdata01\pfOJectsl02511851120\FileRm\R\Critical Areas Rpl\LAP _SoundefPath Critical Areas_rpt.docx LAN DAU ASSOCIATES 3-3 twinberry (Lonicera involucrata, FAC), salmonberry (Rubus spectabilis, FAC), and stinging nettle (Urtica dioica, FAC+). 3.2.1.2 Soils The soil at Sampling Point SP-1 is characterized as a depleted matrix (F3), which satisfies the USACE hydric soils parameters. From O to 4 inches below ground surface (BGS), the soil matrix was a dark grayish brown (IOYR 4/2) loam, underlain by a dark grayish brown loam with gray (IOYR 5/1) and reddish yellow (7.5YR 6/8) redox features from 4 to 21 inches BGS. The soil at Sampling Point SP-2 is characterized as a redox dark surface (F6), which satisfies the USACE hydric soils parameters. From O to 21 inches BGS, the soil matrix was a very dark grayish brown (I OYR 3/2) loam with grayish brown ( IOYR 5/2) and strong brown (7.5YR 4/6) redox features. 3.2.1.3 Hydrology The primary indicator of wetland hydrology observed at Sampling Point SP-I was saturation. The primary indicators of wetland hydrology observed at Sampling Point SP-2 were saturation and a high water table. Surface water was present in other parts of the wetland outside of the sample points. Hydrology for Wetland WI/W2 is primarily from groundwater and runoff from adjacent upland areas. 3.2.1.4 Wetland Determination All three mandatory wetland criteria are satisfied for Wetland W l/W2. Based on review of survey information of a portion of the mitigation area provided by Boeing, the depth of the surface water exceeds 6.6 ft (i.e., deep water habitat); however, active wave-formed or bedrock shoreline features were not observable. As a result, Landau Associates classified Wetland Wl/W2 as a palustrine forested/unconsolidated bottom (PFO/PUB)/depressional (Cowardin/HGM classification) wetland, which constitutes the entirety of the mitigation area as designed. Using the wetland categories provided in Section 4-3-050(M) of the RMC, Wetland W l/W2 is a Category I wetland due to: • The presence of species listed by Federal or State government as endangered or threatened, or the presence of essential habitat for those species (see Table 2) • Wetlands equal to or greater than ten ( I 0) acres in size and having three (3) or more vegetation classes, one of which is open water. As a Category I wetland, Wetland Wl/W2 meets the criteria as a habitat conservation area. Using the Ecology wetland rating form, Wetland Wl/W2 is rated as a Category 2 wetland, with a total score of 55. Wetland Wl/W2 scored highest for hydrologic functions, receiving a score of 24; habitat and water quality functions were rated with a score of 17 and 14, respectively. 4116/13 \\edmdata01\proJects\025\1851120\FileRm\R\CriUcal Areas Rpt\LAP _SounderPath Critical Areas_rpt.docx LANDAU ASSOCIATES 3-4 In accordance with Section 4-3-050(M)(6)(c) of the RMC, Category I wetlands require a 100-ft buffer. Habitat conditions of the buffer are consistent with the upland characterization described below. The buffer in the project area is limited by the existing pathway, which intersects the vegetated habitat. Furthermore, a safety clearance zone is maintained along the pathway, which consists of an approximate 3-to 4-ft-wide area of maintained grass. 3.2.1.5 Upland Characterization The upland area adjacent to Wetland WI/W2 is characterized by Sampling Point SP-3, which satisfies only one of the three mandatory wetland criteria. Sampling Point SP-3 is east of the pathway adjacent to Wetland WI/W2, in the vicinity of the helipad west of Building 25-20. Sampling Point SP-3 is located in the vicinity of an area mapped by the City as wetland. The uplands adjacent to Wetland Wl/W2 consist mostly of grass, shrubs, and trees typical of landscaping associated with commercial properties. Grasses are mowed, and likely consist of Kentucky bluegrass (Paa pratensis, F ACU+ ). Due to maintenance of landscaped areas, much of the area within the sampling point was recently mowed and may be considered a "difficult wetland situation." Vegetation in uplands adjacent to Wetland W I/W2 is dominated by hydrophytic vegetation: • Western red cedar (FA C) • Himalayan blackberry (Rubus armeniacus, FACU) • Vine maple (F AC) • Slough sedge (OBL) • Soft rush (FACW). During the field investigation, the soil of the uplands adjacent to Wetland Wl was moist, but not saturated. The soil from Oto 23 inches BGS was very dark grayish brown (lOYR 3/2) loamy sand. The upland area did not have hydric soils and there were no hydrology indicator; therefore, the only parameter met of the three parameters for a wetland was the hydrophytic vegetation. 3.2.2 HABIT AT CONSERY ATION AREA 0BSERY ATIONS AND FUNCTIONS At the time of the field delineation, waterfowl and songbirds were observed in Wetland WI/W2. Species were not inventoried at the time of the delineation, but active nesting was observed by songbirds in the habitat adjacent to the proposed project. Habitat adjacent to the proposed project is forested, including shrub understory, and tree heights adjacent to the project are approximately 40 to 80 ft. As a Category I wetland, Wetland Wl /W2 meets the criteria as a habitat conservation area. Based on Ecology rating information and field observations, Wetland W I/W2 received a habitat score of 24 points out of36 possible points. Wetland Wl/W2 scored the highest for the following: 4/16/13 l\edmdata011,orojects\02511651120\F1leRm\R\Cntical Areas Rpt\L.AP _SounderPalh Cri1ical Areas_rpt.docx LANDAU ASSOCIATES 3-5 • Hydroperiods • Richness of Plant Species • Interspersion of Habitats.

Project plans are included as reference in Appendix H. 4.1 MITIGATION SEQUENCING Section 4-3-050M(8) of the RMC outlines requirements for mitigation associated with alternations to wetlands and buffers. Mitigation shall be required in the following order of preference: a. Avoid any disturbances to the wetland or buffer b. Minimize any wetland or buffer impacts c. Restore any wetlands or buffer impacted or lost temporarily d. Compensate for any permanent wetland or buffer impacts by one of the following methods: i. Restoring a former wetland and provide buffers at a site once exhibiting wetland characteristics to compensate for wetlands lost ii. Creating new wetlands and buffers for those lost iii. In addition to restoring or creating a wetland, enhancing an existing degraded wetland to compensate for lost functions and values. Section 4-3-050(1)(6)(a) of the RMC states that compensatory storage is required for floodplain fill that reduce the effective base flood storage volume of the floodplain. If grading or other activities reduce the effective storage volume, compensatory storage shall be provided. Section 4-3-050K(5) of the RMC identifies criteria for developing within habitat conservation areas, which includes (a) avoid any disturbance to the habitat, (b) minimize any impact to the habitat, and ( c) compensate for any habitat impacts. 4.1.1.1 Avoidance Wetlands The proposed project is adjacent to the mitigation wetland, but construction does not intersect the wetland boundary and the work is in the already disturbed buffer areas (see Figure 3). Habitat conditions of the wetland buffer affected by the project consist of mowed grasses (i.e., nonfunctioning buffer leading up to the existing path), and disturbed buffer areas will be restored following construction. Floodplain The project will install underground utility lines and limited aboveground facilities, including lighting bollards and stand for electrical disconnect and transformer. The underground utilities will occur in areas below the base flood elevation, but will not result in a change to the existing topography and 4116113 l\edmdata01\projects\025\1851120\FileRm\R\Critical Areas Rpt\LAP _SounderPath Critical Areas_rpt.dacx LANDAU ASSOCIATES 4-1 therefore do not constitute fill within the flood plain. Furthennorc. the aboveground features associated with the project are limited to the proposed lighting bollards and electrical facilities along the trail. The lighting bollards will be installed along the trail at elevation 20 ft or above (NA VD88; see Figure 3), which is above the base flood elevation of 19.5 ft (NA VD88) based on FEMA floodplain mapping. As a result, the underground utilities and light bollards do not impact the base flood storage volume of the floodplain. The floodplain impact associated with the stand for the electrical disconnect and transformer are discussed below in Section 4.1.2 Minimization. Habitat Conservation As discussed above, the proposed project avoids direct wetland impacts. The project will avoid cutting of trees/shrubs; however, selective pruning of low hanging branches may be required during construction (see Section 4.1.2 Minimization). The project will illuminate the walking path; the lights will be installed 48 inches above the ground. The lights have an approximate 180 degree light pattern to minimize illumination of areas outside of the existing path. ln general, the lighting extends approximately 11 ft from the plane of the bollards facing the trail, and approximately 5 ft from the plane of the bollards behind the trail (see Figure 3 and Appendix H). As a result, approximately eight of the twenty-two lights will illuminate portions of the wetland mitigation area; the depth of illumination into the wetland ranges from 0.5 ft to 2 ft, and is limited to heights below the 48-inch lamp height. Illumination avoids nesting habitat in the adjacent forested canopy, subcanopy, and open water areas of the mitigation wetland. 4.1.2 MINIMIZATION Minimization of impacts includes sensitive site design including placement of construction staging areas and site access away from wetlands and the innermost portion of buffers to the greatest extent practicable. Wetlands Section 4-3-050(M)(6)(c) of the RMC includes a condition to direct lights away from wetlands to protect buffer functions. As mentioned above, the buffer of the mitigation wetland in the project vicinity is a nonfunctioning buffer consisting of mowed grass up to the edge of the paved trail (the trail interrupts the remaining buffer). The proposed lighting will consist of approximately twenty-two 42-inch-high 10 watt LED bollards. The lights have an approximate 180 degree light pattern to minimize illumination of areas outside of the existing path. In general, the lighting extends approximately 11 ft from the plane of the bollards facing the trail, and approximately 5 ft behind the trail (see Figure 3 and Appendix H). As a 4116113 l\edmdata01\proJects\025\1851120\FileRm\R\Critical Areas Rpt\LAP _SounderPath Cnt1cal Areas_rpt.docx LANDAU ASSOCIATES 4-2 result, approximately eight of the twenty-two lights will illuminate portions the wetland mitigation area; the area illuminated ranges from 0.5 ft to 2 ft of wetland, limited to heights below the 48-inch lamp height. The extent of this impact is limited to existing edge habitat of the wetland, and avoids the adjacent forested canopy and subcanopy. Floodplains The stand for the electrical disconnect and transformer consists of a steel plate supported by metal stakes 2 ft above the ground surface. The metal stakes would be installed using a concrete anchor support (which would be installed to the existing ground elevation). The metal stakes have an approximate diameter of 2 inches or less. The location of the stand is in an area between 18 ft and 20 ft elevation (NA VD88; see Figure 3); base flood elevation based on FEMA floodplain mapping is 19.5 ft (NA VD88). The metal stakes may be at the base flood elevation, approximately 1.5 ft below, or less than 0.5 ft above the base flood elevation. Based on the relatively small diameter of the metal stakes and elevation at or near the base flood elevation, the volume of the metal stakes, if below the base flood elevation, would not reduce the effective storage volume in the floodplain, and no compensatory storage is proposed. Habitat Conservation The project will avoid cutting of trees/shrubs; however, selective pruning of low hanging branches of tree/shrubs may be required during construction. Pruning would be the minimum necessary to complete project construction. Suitable habitat for listed bird species is not present in the extent of project construction or illumination from the completed project, and those listed species that potentially utilize habitat on the ground in forested areas are not likely to be present or affected by the project. Listed mammals potentially affected by the project include black-tailed deer and meadow vole (see Table 2). As discussed above, selective pruning of low hanging branches of tree/shrubs may be required during construction. Selective pruning associated with construction is not likely to have a significant effect on black-tailed deer habitat or availability of forage. While the limited ground disturbance associated with construction has the potential to disturb meadow vole, this species is likely not present in the project area. This species requires loose organic soil (see Table 2) and soils in the project area are loamy/sandy, and were likely compacted as part of pathway construction. As a result, impacts to meadow vole habitat associated the proposed project are unlikely. 4/16/13 \\edmdata01\projects\02511851120\FileRm\R\Critical Areas Rpt\LAP _SounderPath Cntical Areas_rpt.docx LANDAU ASSOCIATES 4-3 5.0 CONCLUSIONS AND ASSESMENT OF NO NET LOSS The mitigation sequence presented in this report meets City requirements, as outlined in the RMC and meets state and federal agency guidance. The proposed project will provide no net loss of wetland or habitat conservation area functions, and no net loss of floodplain storage capacity. Impacts to these features have been avoided and minimized to the extent that any impacts are discountable and insignificant. 4/16/13 \\edmdata01\projecis\025\185\ 120\FileRm\R\Critical Areas RptlLAP _SounderPath Critical Areas_rpt docx LANDAU ASSOCIATES 5-1 6.0 USE OF THIS REPORT The findings presented herein are based on our understanding of the City of Renton Municipal Code, the USACE and Ecology wetland delineation methodology, and on our interpretation of the vegetative, soil, and hydrological conditions observed during the site visits on March 14, 2013.

Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. Note: Wetlands with State listed plant species are categorized as Category I Natural Heritage Wetlands (seep. 19 of data form). SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW for the state? >( SP4. Does the wetland unit have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance.

This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form -western Washington 2 version 2 Updated with new WDFW definitions Oct. 2008 August 2004 Wetland name or number ~2_/J 2-. Classification of Wetland Units in Western Washington 1. Are the water le O-goto2 ' in the entire uuit usually controlled by tides (i.e. except during floods)? YES -the wetland class is Tidal Fringe '----rf'yv•es, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES -Freshwater Tidal Fringe NO -Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use thefom1sfor Riverine wetlands. !fit is Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (seep. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. ~uum~d surface water runoff are NOT sources of water to the unit. (_____~O -~ 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 both of the following criteria? ~The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m)? ~to 4 YES -The wetland class is Lake-fringe (Lacustrine Fringe) ~he entire wetland unit meet all of the following criteria? ~-The wetland is on a slope (slope can he very gradual), ~_The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. ___ The water leaves the wetland without being impounded? NOTE: Surface water does not pand in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usual~v la-) <3fl diameter and less than I foot deep). u go to 5 YES -The wetland class is Slope Wetland Rating form -western Washington 3 version 2 Updated with new WDFW definitions Oct 2008 August 2004 Wetland mime ur number //J/ / f.,.J ·7-- 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 two years. NOTE: The riverine unit can contain depressions that are filled with water when the river is ~ jlooding. (___7go to 6 YES -The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wet~at NO -go to 7 YES -he wetland class is Depressional 7. Is the entire wetlan 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 clases. 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 HYDRO LOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than I 0% of the unit; classify the wetland using the class that represents more than 90% of the total area. .

Kaiser Consulting Wildlife Biologist Osprey Solutions, LLC April 15, 2013 1.0 INTRODUCTION Office: 206-938-1600 Mobile: 206-909-4283 jim_kaiser@comcast.net • Osp~ Solutions LLC The Osprey {Pandion holiaetus), one of the most admired raptors, captivates birdwatchers with its dramatic feet-first plunges from a hover high above the water to capture fish. This charismatic, eagle-size bird often mates for life and build large conspicuous nests near shallow water, returning to the same nest each year. For birdwatchers, they are a delight as Ospreys are reasonably tolerant of human activity at nesting and foraging areas in the Pacific Northwest where they raise their young over a five-month period (April-September). Osprey populations in the United States suffered great declines in the past century as result of DDT and other eggshell-thinning pesticides. Since the ban of DDT in 1972, the Osprey has made, and continues to make, a strong comeback in much of North America with birds reoccupying former breeding areas and moving into new areas. Provisioning of artificial nesting platforms for Ospreys dates back to 1904 when cartwheels were commonly placed on poles in Rhode Island. The practice in recent years has significantly increased nesting opportunities in many areas and helped osprey populations recover, especially within the East Coast and Great Lakes Osprey populations. In King County, Washington, nest site availability for Ospreys in live or dead trees has been severely limited by habitat loss. Currently, most Osprey nests in Washington and Oregon are built on artificial structures like cell towers, light poles and power poles. Osprey use of these structures presents risks to birds {electrocutions and wire collisions) and system reliability {nest-caused outages and structure fires). The Boeing Company seeks to help enhance nesting habitat for Ospreys in the Duwamish-Green River watershed by installing an artificial "snag" {nesting platform) at its Commercial Airplane headquarters at Longacres Park in Renton, Washington {Figure 1). This habitat enhancement project will benefit Osprey by providing a safe, alternative nesting structure for an expanding breeding population. Potential company and public benefits include enhanced wildlife diversity and viewing opportunity from Boeing Longacres Park, King County Interurban Trail, and the Amtrak Tukwila station. An educational brochure of Osprey habits {See: http://trescusgs.gov/products/f,/fs 1 S3 02.µdf) could be placed In future-built kiosks. This habitat enhancement project addresses important environmental conservation and public outreach program objectives of the Boeing Company and is another example of Boeing's environmental stewardship in action. • 2.0 METHODS A preferred location for erecting an Osprey platform within the Longacres Park campus was identified during a site visit with Darrel DeNune, Boeing Site Services (Grounds) of the Shared Services Group on April 5, 2013. Site visit information was collected and used to evaluate the suitability of the preferred location and the probability of success in attracting breeding Osprey to the new nesting site based on consultant's experience with similar projects and a review of Osprey nesting requirements (e.g., Poole et al., 2002). Site selection considerations included: a) distance from water or foraging areas, b) proximity to other nesting raptors, c) proximity to thickly forested woodlands, d) height of nearest adjacent trees, e) ease of public viewing, f) potential disturbance by people, industry, or pets, g) land ownership, h) visual evaluation of soil conditions at the site, i) ease of equipment access for pole installation, and j) potential impacts to sensitive areas from installation. In addition, consideration was given to areas where Ospreys are currently nesting or attempting to nest on inadequate structures (e.g., power poles or cellular towers) in the local area. The best opportunities for attracting breeding Ospreys into an area are when breeding pairs already occur within about 12 mi. (Ewins 1994). Based on field surveys, review of aerial images, input from Boeing employees at the Longacres campus, and personal knowledge of existing Osprey nest locations and foraging habits in the Seattle-Tukwila-Renton area, the proposed site was selected as a suitable location for erecting an Osprey nesting platform with a good probability of success in attracting a pair of breeding osprey to the new nesting structure. 3.0 SITE-SPECIFIC FINDINGS The proposed pole-platform site is located at the western perimeter of Boeing Longacres Park adjacent to tall snag used as preferred perch by Osprey at neighbor nest site on cell tower located 0.19 mi northwest of proposed nest pole. Osprey Nest Pole Location: SW corner of South Pond (47°27'3S.28N", -122°14'19.GG"W) Description: The proposed nest pole location is at the west boundary of the open space at the southwest corner of south pond. The pole would be erected 330 feet west of the south tip of south pond and 75-ft northeast of a tree snag at edge of abandoned concrete roadway. Distance from the south pond to the pole work site is 238 feet (Figure 2). Key Issues: Road access to the pole site at the edge of concrete roadway and meadow is good. Digger-derrick truck can access the work site from powerline access road at south end of the park then onto abandoned concrete roadway to install pole in soil at west edge of meadow adjacent to existing snag. Ground elevation at proposed pole site is 21-ft. Soil condition appears to be firm near surface, with softer soil likely at depth. Recommend embedding pole 10' on 6" concrete footing and backfill hole with lean concrete 2000 psi. Recommend clearing all volunteer cottonwood saplings (50 trees) and a small group of Scotch Broom shrubs within 150 foot radius of proposed nest pole location for best opportunity to attract Osprey to the nesting platform and to enhance wildlife viewing opportunities. Leave snags and trees within the established wetland conservation area east of the pole site undisturbed. The nesting platform will be visible to pedestrians using the trail circling the south pond and the paved walkway bisecting the north and south ponds that provides access between Boeing Commercial Airplane headquarters and the Tukwila Amtrak/Sounder train station. Train passengers and public using the Interurban Trail east of Longacres Park could view nesting birds with aid of binoculars. 2 # 4.0 WORK PLAN DETAILS The Osprey nesting platform selected for this project is the same design installed by Osprey Solutions LLC at several locations in the Puget Sound area (e.g., NOAA Western Regional Center, King County DNRP , and Seattle City Light) and used by Osprey to raise young . Details for platform construction and nest pole installation are provided in Attachment A and B. The proposed dates for pole to be delivered to Longacres park and subcontractor to erect the 50-ft wood pole and nesting structure is April 17-30, depending on permit approval.
