The project site extends across the length of the Bridge (approximately 200 feet) between the east and west banks of the LCR (Figures 3 and 4). The proposed project consists of the following elements: • Place light-emitting diode (LED) lamps along footpath on the Bridge (Figures 3, 4, and 5); and; • Install two 3-foot by 5-foot solar panels on the Bridge (Figures 3, 4, 6 and 7). The City of Renton expressed concerns regarding potential light impingement on the adjacent LCR resulting from installation of new light fixtures on the Bridge. The focus of this study is to assess potential habitat alteration to the LCR and its associated riparian habitat due to the proposed installation of LED lighting along the footpath of the Bridge. Boeing's proposed lighting installation is being conducted to improve safety at the facility for Boeing employees and contractors who must work at night. The proposed plan will install a 200-foot-long, 24-volt, 250-watt LED amber-hued rope lighting across the entire length of the Bridge along the footpath on the south side of the Bridge (Figures 3 and 4). The proposed lights (587 nanometer wavelength) will have a luminous flux of 14.9 lumens per foot and the 200 linear feet of lighting will only add a total of 2,980 lumens to the Bridge walkway (equivalent to one 4-foot fluorescent tube, but amber instead of white). The lights will be mounted on the bridge curb only 9 inches off the ground with lighting directed horizontally across the walkway (Figure 5). The use of LED amber-hued lighting and its placement at near deck level will prevent errant light from illuminating the underlying LCR. The bridge deck is constructed of solid concrete rather than grating, so that there are no gaps in the bridge deck through which light can reach the underlying river. Lights will be powered by a stand-alone system of two 3-foot x 5-foot solar panels and battery storage units. The solar panels will be mounted on the south side of the bridge structure, one on the east end and one on the west end, landward of the ordinary high water mark (OHWM) (Figures 3, 4, 6, and 7). No construction activities will occur and no structures will be placed below the OHWM. The proposed Amee Foster Wheeler Project No. L Y1 4160300 1 p:\boeing renton~y14160300 s bridge lighting lake-stream\reportslstreamstudy\streamstudy _ habilatdatarpt_ 011315.docx ~ amec t, foster wheeler use of LED lighting is also expected to be more environmentally sustainable, substantially decreasing energy consumption when compared to other types of lighting such as incandescent, halogen, and mercury vapor.

The project site is defined as the South Aircraft Bridge where it crosses the LCR approximately 3,950 feet south of its mouth, where it discharges to Lake Washington. The South Aircraft Bridge is used by Boeing to transport aircraft (i.e., 737s) from Boeing's production facility located on the east side of the LCR to the Renton Municipal Airport where the planes are launched and landed. The Boeing facility and the Renton Municipal Airport consist primarily of concrete and asphalt surfaces. A vegetation survey was conducted along the east and west banks of the LCR adjacent to and extending 100 feet upstream and downstream of the South Aircraft Bridge (Figure 2). Appendix A provides a photo log depicting habitat conditions and vegetation along the riparian zone of the east and west banks of the LCR adjacent to the project site. The riparian zone along the west bank of the LCR south of and within 100 feet of the Bridge is narrow (6 to 12 feet wide), abutting an 8-foot-high concrete flood-control wall (Appendix A, Photos 1, 2, 4, and 9). Riparian vegetation at the time of the visit was very sparse and was limited primarily to patches of reed canarygrass (Phalaris arundinacea), Japanese knotweed (Polygonum cuspidatum), horsetail (Equisetum f/uviatile), Himalayan blackberry (Rubus armeniacus), and alder (A/nus rubra) (Appendix A, Photos 5 through 9). Reed canarygrass, Japanese knotweed, and Himalayan blackberry are listed as noxious weeds by King County. The width of the riparian area is limited by the concrete flood-control wall (Appendix A, Photos 1 and 2). No trees with trunks greater than or equal to 10 inches in diameter at breast-height (DBH) are located within 100 feet of south of the Bridge on the west bank. The west bank of the LCR within 100 feet north of the Bridge is more heavily vegetated than that south of the Bridge (Figure 2 and Appendix A, Photos 10 through 12). Vegetation on the west bank of the LCR within 100 feet north of the Bridge consists of alder, unidentified species of willow ( Salix Amee Foster Wheeler Project No. L Y14160300 7 p:lboeing renton\ly14160300 s bridge lighting lake-stream\reports\streamstudy\streamstudy _ habitatdatarpt_ 011315.docx ~ amec fee .. foster wheeler spp.), reed canarygrass, Japanese knotweed, and Himalayan blackberry, as well as an unidentified species of evergreen tree. No trees with trunks greater than or equal to 10 inches DBH are located within 100 feet north of the Bridge on the west bank. The east bank of the LCR within 100 feet south of the Bridge is more heavily vegetated than the west bank south of the Bridge (Figure 2 and Appendix A, Photo 13). Riparian vegetation on the east bank south of the Bridge is similar to that located on the west bank north of the bridge, with the exception that the riparian corridor is not confined by a fiood-control wall. The Cedar River Trail Park, maintained by the City of Renton. is located along the east bank of the LCR and consists of manicured lawns, ornamental shrubs and native vegetation (Appendix A, Photo 15). An 8-foot-wide asphalt pedestrian path is located in the Cedar River Trail Park, within 60 feet of the LCR. The Boeing plant is located within 75 feet of the LCR (Figures 1 and 2). No trees with trunks greater than or equal to 10 inches DBH are located within 100 feet south of the Bridge on the east bank. The vegetation on the east bank of the LCR within 100 feet north of the Bridge is similar to that south of the bridge (Appendix A, Photos 14 through 18). The Cedar River Trail Park extends north to the Boeing property at the mouth of the LCR and consists of manicured lawns, ornamental shrubs and native vegetation, and an asphalt pedestrian path (Figure 2 and Appendix A, Photo 15). No trees with trunks greater than or equal to 10 inches DBH are located within 100 feet north of the Bridge on the east bank. 2.3 ECOLOGICAL FUNCTION Riparian habitats have important ecological functions other than providing habitat for birds and other wildlife. Healthy riparian vegetation protects banks from erosion, infiuences in-channel aquatic habitats, maintains favorable water temperature for fish through shading, filters runoff, and provides nutrients. Riparian vegetation creates meanders, increases habitat complexity, and can protect against scour during severe storm events. Riparian habitats link upland and aquatic habitats. Upland habitats have a critical role in watershed function and affect riparian and aquatic habitats, particularly in drier, low-elevation sites. The riparian zone along the east and west banks of the LCR within 100 feet of the project site is sparsely vegetated and includes a number of invasive species, as discussed in Section 2.2, above. The primary ecological functions provided by riparian vegetation along the east and west banks of the LCR within 100 feet of the project site include: • Nesting and foraging habitat for birds and small mammals, • Input of terrestrial insects from overhanging vegetation. Amee Foster Wheeler 8 Project No. LY14160300 p:lboeing renton\ly14160300 s bridge lighting lake-stream\reports\streamstudy\streamstudy_habrtatdatarpt_011315.docx 1$ amec a,: • Input of allochthonous organic matter (via leaf fall), • Limited erosion control, and • Limited habitat complexity. foster wheeler The LCR is a man made channel created in 1912 when the river was diverted as a tributary to the former Black River directly to Lake Washington. The LCR is channelized and substantially altered, so that there is very limited riparian area to provide all of the potential ecological functions of an unaltered habitat. Riparian vegetation provides very little, if any, shading to the LCR because of the dominance of small shrubs and the lack of large trees. Both banks of the river in the project area are contained within levees and/or flood-control walls, so there is no potential for the creation of meanders or off-channel habitat. Because of extensive development along both banks of the river in the project area (Boeing to the east and west and the Renton Municipal Airport to the west), there is little, if any, transition between riparian and upland habitats. 2.4 FISH AND WILDLIFE This section addresses fish and wildlife species that may use the LCR in the vicinity of the project site. 2.4.1 Mammals No mammals or signs of mammal use were observed during the site visits. Given the level of development in the project area, it is likely that only small mammals such as squirrels, mice, rats, voles, moles, raccoons, opossums, muskrats, and river otters use the riparian areas along the LCR shoreline within 100 feet of the project area. Richter and Azous (1997), conducting small-mammal surveys in a wetland along the LCR, reported 13 species of mammals (Table 1). These, as well as other small mammals common to the Puget lowlands, may occur along the LCR adjacent to the project site. 2.4.2 Birds Several bird species were observed during the site visits, inciuding American crow ( Corvus brachyrhynchos), American robin (Turdus migratorius), Canada goose (Branta canadensis) and European starling (Sturnus vulgaris). Richter and Azous (1997) conducted bird surveys in a wetland of the LCR between late May and mid-June in 1988, 1989, 1991 1992, and 1995 to determine distribution and relative abundance. They reported 58 species of birds (Table 2). It is likely that these, as well as other species of birds common to the Puget lowlands, nest or forage in the project vicinity. 2.4.3 Amphibians and Reptiles No amphibians or reptiles were observed during the site visits; however, it is likely that amphibian (e.g., Anurans) and reptile species (e.g., turtles) found in the Lake Washington basin may use the Amee Foster Wheeler Project No. LY14160300 9 p:\boe1ng renton1Jy1 4160300 s bndge lighting lake-stream\reports\streamstudy\streamstudy _ habijatdatarpt_ 011315.doc:< '~ amec ~~ foster wheeler areas within the site vicinity. Richter and Azous (1997) reported the occurrence of six amphibian species in the LCR: • Ensatina (salamander) (Ensatina eschscholtzii), • Long-toed salamander (Ambystoma macrodactylus), • Northwestern salamander (A. gracile), • Pacific tree frog (Pseudoacris regil/a), • Red-legged frog (Rana aurora), and • Western red-backed salamander (Plethodon vehiculum). No information was located listing reptile species occurring along the LCR in the project vicinity; however, reptiles listed for King County (King County, 2008) that could occur in the project vicinity include: • Common garter snake (Thamnophis sirtalis), • Northern alligator lizard (Elgaria coerulea), • Northwestern garter snake (T. ordinoides), • Painted turtle ( Chrysemys picta), • Rubber boa ( Charina bottae ), • Slider (Trachemys scrip/a), • Western fence lizard ( Sceloporus occidentalis), and • Western terrestrial garter snake ( T. elegans). 2.4.4 Fish Small fish were observed jumping in the LCR adjacent to the project site during the site visits. Although they could not be identified, they appeared to be small salmonids. The Lake Washington system, including the LCR adjacent to the project site, hosts many fish species, including five salmonid species: Chinook salmon (Oncorhynchus tshawytscha), coho salmon (0. kisutch), sockeye/kokanee salmon (0. nerka), coastal cutthroat trout (0. clarki clark1), and steelhead/rainbow trout ( 0. mykiss). Anadromous forms of each of these species use the Cedar River system as migratory, forage, nursery, and spawning habitat, so individuals are present in the river both as adults during migrations to spawning grounds and as juveniles (Kerwin, 2001 ). All of these species occur seasonally in the LCR adjacent to the project site. Additionally, there have been isolated reports of coastal/Puget Sound bull trout ( Sa/velinus confluentus) occurring in the Lake Washington system; however, it is believed that few bull trout occur in the Lake Washington system, if they occur at all. Amee Foster Wheeler 10 Project No. L Y14160300 p:\boeing renton\Jy14160300 s bridge lighting lake-stream\reports\streamstudy\s1reamstudy_ habrtatdatarpt_ 011315.docx amec~ foster wheeler Puget Sound Chinook salmon, Puget Sound steelhead trout, and bull trout are federally-listed species under the Endangered Species Act. Nonanadromous forms of winter steelhead (rainbow trout), sockeye (kokanee), and cutthroat trout may also occur in the LCR. Resident rainbow trout spend their entire life in the Lake Washington system. The resident rainbow trout population was sustained with hatchery plants because they rarely successfully reproduce in Water Resource Inventory Area (WRIA) 8; however, releases of hatchery rainbow trout have been all but eliminated. Nonanadromous coastal cutthroat trout also occur in the Lake Washington system and are much more abundant than the anadromous form. Kokanee salmon is the freshwater, resident form of 0. nerka. Some progeny from the parents of anadromous sockeye may also remain in Lake Washington for all or a portion of their lives (resident/anadromous sockeye) (Kerwin, 2001 ). The largest single population of adfluvial bull trout in western Washington is found above Cedar Falls in the upper Cedar River watershed. It is believed that a small number of bull trout pass through the reservoir and downstream hydroelectric facilities to the river reaches below Cedar Falls. However, it is apparently not sufficient to support the establishment of bull trout populations under the current ecological conditions (Corps, 2002). Native char, presumably bull trout, have been observed in the fish ladder viewing pool at the Hiram M. Chittenden Locks as recently as 1997, while isolated reports of native char being caught in or around Lake Washington occur every few years. A large juvenile char, again, presumably a bull trout (-250 millimeter [mm], 3 year old), was caught in the LCR in July 1998. An adult char was also caught in the LCR in April of 1993 (Corps, 2002). Based on this information, occurrence of bull trout in the LCR adjacent to the project site is expected to be extremely limited, if they occur at all. Species endemic to the Lake Washington system include the northern pike minnow (Ptychocheilus oregonensis), peamouth (Mylocheilus caurinus), sculpins (Coitus spp.), and longfin smelt (Spirinchus thaleichthys) (Weitkamp et al., 2000; Wydoski and Whitney, 2003). Twenty-four non-native fish species (Table 3) have been identified in the Lake Washington/Lake Union system. A number of these species are now believed to be no longer present in the system. Some of these species are known to prey on juvenile salmon (e.g., smallmouth bass) while others are potential competitors with juvenile salmonids for food (Kerwin, 2001 ).

No direct or indirect impacts to riparian vegetation or trees will occur as a result of the proposed project; therefore, no measures to protect vegetation or trees have been incorporated into the work plan. 2.6 No NET Loss OF ECOLOGICAL FUNCTION The project will result in no net loss of ecological function in the riparian zone of the LCR adjacent to and 100 feet upstream and downstream of the Bridge. As described above, the LCR adjacent to the project site provides limited ecological function due to low habitat diversity and complexity.

Subsequent sections of the report will discuss following: • The layers, diversity and variety of habitat found on the site; • The location of any migration or movement corridors; • The species typically associated with the cover types, including an identification of any critical wildlife species that might be expected to be found; • Identification of any areas that have been previously disturbed or degraded by human activity or natural processes; • A summary of existing habitat functions and values; and • A summary of proposed habitat alterations and impacts and proposed habitat management program. 3.1 HABITAT DIVERSITY The LCR downstream of 1-405 (approximately 1.6 miles) is an artificial channel created early in the 20'h century and is completely constrained between levees and revetments. This reach was regularly dredged to prevent flooding from the time of its completion in 1912 until the mid-1970s. Portions of the reach were again dredged in 1999 for the first time since the mid-1970s. Flood-control dredging is proposed during the summer of 2015. In-stream habitat in the reach is almost entirely glide, with little habitat complexity. Land uses prevent floodplain connectivity and have eliminated the potential for re- connection with a natural floodplain or the establishment of a riparian corridor. Channelization and existing land uses also prevent significant large woody debris (LWD) from accumulating in the channel. The reach is also very low-gradient and depositional, and the substrates have high levels of fine sediments (Corps, 2004; Parametrix and Adolfson, 2010). The shoreline along the LCR adjacent to the project site consists of developed property belonging to Boeing and the City of Renton. With realignment of the Cedar River into Lake Washington in 1912, the zone of sediment deposition was localized through the City of Renton (Perkins, 1994 ). The vast majority, if not all, of the non- suspendable sediment load is now deposited along this reach because Lake Washington lies at the river's mouth. With the path of the river fixed by armored banks, progressive infilling of the channel resulted. Sediment is continually deposited in the downstream 2 miles of the river and in an enlarging delta in Lake Washington. Amee Foster Wheeler Project No. LY14160300 13 p:\boeing renton\ly14160300 s bridge lighting lake-stream\reports\streamstudy\streamstudy_habrtatdatarpt_011315.docx ! amec~ foster wheeler Aquatic habitat within the LCR adjacent to the project site consists of a low relief benthic habitat composed of small cobbles with some gravel and no boulders. LWD in the stretch of the LCR adjacent to the project site is extremely limited (Appendix A, Photo 1 ). River discharge at the time of the site visits in May and November 2014 was approximately 1,000 cubic feet per second (USGS, 2014). Channelization of the LCR has eliminated meanders within the lower river, such that the lower 1.6 miles of river consists of a uniform glide habitat with a nearly complete absence of riffles and pools. Habitat diversity along the LCR adjacent to the project site is extremely limited. 3.2 MIGRATION CORRIDORS A query of the Washington Department of Fish and Wildlife's Priority Habitat and Species (PHS) database (http://wdfw.wa.gov/mapping/phs/) identified five salmonid species that use the LCR as a migration corridor: • Chinook salmon; • Coho salmon; • Sockeye salmon; • Steelhead and rainbow trout; and • Coastal cutthroat trout. Two of the above species, Puget Sound Chinook salmon and Puget Sound steelhead trout. are listed as threatened under the Endangered Species Act. Bull trout, a member of the char family, may also be found in the LCR and is also listed as threatened under the Endangered Species Act. Population status information and extent of use of this area is currently unknown. Adult and subadult size individuals have been observed infrequently in the LCR (below Cedar Falls), Lake Washington, and at the Locks. No spawning activity or juvenile rearing has been observed and no distinct spawning populations are known to exist in Lake Washington outside of the upper Cedar River above Lake Chester Morse (not accessible to bull trout within Lake Washington) (NOAA-Fisheries and USFWS, 2008). It is unlikely that bull trout use the Cedar River as a migratory corridor. 3.3 SPECIES AND COVER TYPES The almost complete absence of riparian vegetation along the west bank of the LCR and the limited riparian vegetation along the east bank adjacent to the project site and the highly developed shorelines along both banks of the LCR severely limit habitat availability and use by multiple plant and animal species. The concrete flood-control wall on the west bank of the LCR adjacent to the project Amee Foster Wheeler 14 Project No. LY14160300 p:lboeing renton\Jy14160300 s bridge lighting lake-stream\reports\streamstudy\streamstudy_ habitatdatarp\_ 011315.docx ]if amec _i foster wheeler site severely limits the width of the riparian zone and eliminates the transition zone from riparian to terrestrial habitats. Typical plant and animal assemblages and associations that would be expected along the riparian corridor of the LCR are, for the most part, absent along the stretch adjacent to the project site. A query of the Washington Department of Natural Resources' Natural Heritage Program online data base (http://www.d n r. wa .gov /Resea rchScie nee/How To/Conservation Restoration/Pages/ amp_nh_data_order.aspx) did not identify any plant or terrestrial animal species of special concern in the vicinity of the project site. Critical wildlife species occurring at the project site include those salmonids identified in Section 2.4.4 above. 3.4 IDENTIFICATION OF DISTURBED AREAS The entire project area is highly developed and disturbed. As stated in Section 3.1 above, the lower 1.6 miles of the LCR is an artificially-created channel with extensive development along both banks. 3.5 EXISTING HABITAT VALUES AND FUNCTIONS The LCR adjacent to the project site has very limited habitat value and is low functioning. A combination of two habitat assessment methods was used to provide a qualitative assessment of the existing habitat values and functions. These habitat assessment methods were the U.S. Environmental Protection Agency's (EPA's) Rapid Bioassessment Protocols for Use in Wadeable Streams and Rivers (Barbour et al., 1999) and the U.S. Forest Service's Stream Inventory Handbook: Levels I and II (USFS, 2010). Both methods incorporate the use of physicochemical and biological parameters to assess habitat value and functionality. The EPA's Rapid Bioassessment Protocols incorporates both benthic invertebrate and fish assemblages' data in evaluating habitat value and function. For the purposes of this project, neither benthic invertebrate nor fish assemblage data were collected as part of the evaluation process due to the necessity of applying for and receiving the necessary permits to gather such data. The habitat assessment is based on physicochemical conditions observed at the project site: • Temperature; • Water quality; • Reach sinuosity; • Vegetative conditions of the stream banks and the riparian zone; and • Condition of the floodplain (e.g., accessibility from the bank, overflow, and size). Amee Foster Wheeler Project No. LY14160300 15 p:lbooing renton\ly14160300 s bridge lighting lake•stream\reports\streamstudy\streamsludy _ habitatdatarpt_ 011315.docx ~ amec 7;"'!!' foster wheeler Each of the above parameters is discussed below. 3.5.1 Temperature Mean monthly water temperatures (°C) in the LCR at Renton for the period of 1992 through 2013 (USGS, 2014) are as follows: • January -6.0; • July-15.5; • February -6.4; • August -15.8; • March -7.6; • September-13.7; • April -9.4; • October -10.9; • May-11.5; • November -8.1 ; and • June -13.2; • December -6.3 . The warmest water temperatures occur during the months of June, July, August, and September; however, even the highest mean monthly temperatures are compliant with Washington State aquatic life temperature criteria (Table 4 ), with the exception of the char spawning and rearing beneficial use. Char (e.g., bull trout) do not spawn in the LCR and it is highly unlikely that they use the LCR as rearing habitat. 3.5,2 Water Quality No site-specific water quality data were found for the project site; however, water quality monitoring has been conducted in south Lake Washington by the Washington State Department of Ecology (Ecology). Washington State's Water Quality Assessment [303(d) & 305(b) Report] (Ecology, 2008) identified exceedances of water quality standards for temperature, pH, dissolved oxygen, and fecal coliforms in the LCR. No chemical exceedances of state water quality criteria were identified for the LCR adjacent to the project site. 3.5.3 Reach Sinuosity As discussed above, the lower 1.6 miles of the LCR are channelized and much of the shoreline on both banks is restrained by bulkheads. There is no sinuosity within the entire 1.6 miles of the LCR. Stream sinuosity can provide increased habitat complexity through the creation of pools, riffles, and glides, as well as the creation of off-channel habitat. 3.5.4 Vegetative Conditions As described previously, riparian vegetation is sparse along the both banks of the LCR within 100 feet of the project site. As such, habitat diversity and functionality along this reach of the LCR is severely limited. Amee Foster Wheeler 16 Project No. LY14160300 p:\boeing renton\Jy14160300 s blidge lighting lake-stream\repo<ts\streamstudy\streamstudy_ habitatdatarp\_011315.docx 3.5.5 Floodplain Condition 1$ amec i foster wheeler The LCR is an artificially-created channel confined by levees and bulkheads on each bank. Except in extreme discharge conditions, the LCR has very little connectivity with its floodplain and virtually no potential for formation of off-channel habitat within the floodplain. Because of the low gradient of the LCR, it functions as a sediment depositional zone. The City of Renton and the U.S. Army Corps of Engineers periodically dredge the LCR for flood-control purposes. The City of Renton is proposing flood-control dredging for the summer of 2015. 3.5.6 Habitat Values and Functions at the Project Site A qualitative assessment of the LCR adjacent to the project site indicates that it provides very low habitat value and function due primarily to the sparse riparian vegetation and habitat complexity. 3.5.7 Habitat Alterations and Impacts and Proposed Habitat Management Program The project will not involve any in-water components, nor will any portion of the project occur in the riparian zone of the LCR. The one component of the project that could potentially affect aquatic biota in the LCR is light impingement from the additional lighting proposed for the Bridge. The proposed lights will be amber (587 nanometer wavelength) with a luminous flux of 14.9 lumens per foot. The 200 linear feet of lighting will only add a total of 2,980 lumens to the Bridge walkway (equivalent to one 4-foot fluorescent tube, but amber instead of white). Because the lights will be mounted only 9 inches above the bridge deck and directed horizontally across the walkway, there will be no direct light impingement on the surface water of the LCR. Additionally, the proposed solar panels and battery storage units mounted on each end of the south side of the bridge will be located landward of the OHWM, so there will be no overwater shading attributable to these structures. Therefore, the project will not alter existing habitat conditions along the LCR. No habitat management or mitigation program is required for this project and none are proposed.
