Project Design Drawings Appendix B. Species Lists February 16, 2022 | Page 1 File No. 0693-078-01 1.0 INTRODUCTION The City of Renton (City) is proposing to complete the Cedar River 205 Levee Certification Project, which consists of improvements to the existing Cedar River levee system to meet current flood design standards necessary for levee certification. The existing flood protection system is located on both banks of the lower Cedar River within the limits of the City of Renton, Washington. The levee system consists of earthen levee embankments (levees) and floodwalls along both banks of the lower 1.25 miles of the Cedar River between the river mouth at Lake Washington and just upstream of the Logan Avenue Bridge, as shown on the attached Cedar River Section 205 Levee System Improvement Locations Overview and Vicinity Map (Figure 1). As part of the recertification process, deficiencies in the flood protection system have been identified and will be corrected. 1.1. Purpose and Need The certification of the Cedar River Section 205 Levees was considered invalid by the U.S. Army Corps of Engineers (USACE) in August 2013. The Federal Emergency Management Agency (FEMA) granted a provisional accreditation status in 2016, with the expectation that the City is continuously working on accreditation. Leaving the levee unaccredited would remove the levee from the Flood Insurance Rate Map (FIRM) as providing protection for the 100-year recurrence interval flood event. This would change the flood hazard area protected by the levees from Zone X to Zone A, which would enforce floodplain management regulations and federal mandatory purchase of flood insurance. The area protected by the levees includes Renton Municipal Airport, the Boeing Commercial 737 Airplane Production Facility, the Renton Senior Center, the regional Cedar River Trail park and residential/commercial areas on both the left and right banks. Reclassifying the floodplain as a special flood hazard area would create gross economic and developmental impacts. The purpose of this Biological Assessment (BA) is to satisfy consultation requirements under Section 7 of the Endangered Species Act (ESA) in support of the Conditional Letter of Map Revision (CLOMR) application to FEMA, which will include proposed levee system improvements to meet current design standards and is intended to result in approval of levee modifications necessary to recertify the flood protection system. An Essential Fish Habitat (EFH) evaluation is also included for Magnuson Stevens Fishery Conservation and Management Act (MSA) compliance. GeoEngineers, Inc. (GeoEngineers) was subcontracted by Tetra Tech, Inc. (Tetra Tech) to prepare this BA report on behalf of the City. This document has been prepared based on current levee system improvement designs advanced to a 75 percent design level. 1.2. Project Location The project reach is located on the Cedar River upstream (south) from its mouth at the south end of Lake Washington in Renton, Washington, within Township 23 North, Range 5 West, Sections 7 and 18. Proposed improvements are located from just upstream (south) of the Logan Avenue bridge downstream (north) to the river mouth at Lake Washington, which defines the project reach (site) for purposes of analysis. Additionally, the proposed improvements occur at discrete locations within the project reach where levee deficiencies have been documented, but do not encompass the entire levee system. The analysis of impacts was therefore limited to the specific areas where improvements are proposed. A Vicinity Map and Improvement Locations Overview is included as Figure 1. February 16, 2022 | Page 2 File No. 0693-078-01 1.3. Site Description There are three bridges within the project reach, including (from upstream to downstream): Logan Avenue Bridge, South Boeing Bridge and North Boeing Bridge. Renton Municipal Airport is located west of the left bank of the lower river, and Boeing facilities and a public park (Cedar River Trail Park) are located east of the right bank of the lower river below Logan Avenue. Other commercial, industrial and residential developments are present upstream (south) of Logan Avenue. Within the project reach, between river mile 0 and 1.23, the Cedar River is a constructed channel that historically has required periodic maintenance dredging to reduce the bed elevation and ensure flood protection to surrounding areas. The river is channelized through the project reach and the banks are armored in numerous areas with riprap, concrete, gabion baskets and/or wood retaining walls. Vegetation within the riparian zone along this stretch of the Cedar River is comprised of a mix of: mature native trees and shrubs; recently planted native trees, shrubs and herbaceous species that were installed as mitigation for the most recent maintenance dredging cycle, which was completed in 2016; park landscaping trees, shrubs and mowed grasses; unmaintained grass areas; and sections dominated by invasive species. Native tree species located within the riparian zone include red alder (Alnus rubra), Pacific willow (Salix lasiandra), Sitka willow (Salix sitchensis) and black cottonwood (Populus balsamifera ssp. trichocarpa). Additional native shrubs and herbaceous species within the riparian zone include vine maple (Acer circinatum), snowberry (Symphoricarpos albus), Nootka rose (Rosa nutkana), clustered wild rose (Rosa pisocarpa), redosier dogwood (Cornus sericea), twinberry (Lonicera involucrate), Pacific ninebark (Physocarpus capitatus), sword fern (Polystichum munitum), lady fern (Athyrium filix-femina) and scouring rush (Equisetum hyemale). Many of these species were recently installed. Typical invasive species include Japanese knotweed (Polygonum cuspidatum), reed canarygrass (Phalaris arundinacea), Himalayan blackberry (Rubus armeniacus) and Scotch broom (Cytisus scoparius). 2.0 DESCRIPTION OF THE PROPOSED ACTION 2.1. Project Description The proposed levee improvements include minor modifications at eight improvement sites associated with the existing levee and floodwall system along both the left and right banks of the Cedar River. Project design drawings are provided as Appendix A, Project Design Drawings, showing the locations of each improvement area in detail. A summary of the proposed locations and description of improvements are provided in Table 1 below: February 16, 2022 | Page 3 File No. 0693-078-01 TABLE 1. SUMMARY OF LEVEE IMPROVEMENT AREAS Location (Levee Stationing) Description of Improvement Right Bank 49+60 Improve Floodwall to Embankment Transition. The existing floodwall will be embedded into an elevated embankment. The embankment will be elevated using common borrow material. See Sheet C-111 in Appendix A for more details. 63+50 to 64+20 Raise Levee Embankment. Adjacent to the trail, the existing embankment will be raised by adding common borrow. The crown width of the embankment is 8 feet. See Sheet C-112 in Appendix A for more details. 65+50 Replace Sidewalk. The sidewalk will be reconstructed in its existing alignment to slightly raise the elevation in compliance with levee crest requirements. See Sheet C-113 in Appendix A for more details. 66+35 to 68+85 Raise/Extend Floodwall. Approximately 3.5 feet from the Senior Center Building, a new floodwall will be installed. This will require removal of existing shrubs and excavation to install the floodwall footing and floodwall. The reinforced concrete floodwall is approximately 4 feet wide and buried approximately 3 feet into the ground. See Sheet C-114 in Appendix A for more details. Left Bank 19+20 Improve Transition from Levee Embankment to Wall. An additional 26 linear feet of floodwall will be added to the existing floodwall. This will require excavation of approximately 5 feet to install the floodwall footing and reinforced concrete floodwall. The excavation area will be backfilled with excavated native material or substituted fill that meets specifications. See details on Sheet C-101 in Appendix A for more details. 26+50 to 29+60 Raise Floodwall. The existing floodwall will be raised with a cast-in-place concrete cap. See Sheets C-102 and C-104 in Appendix A for more details. 29+60 to 33+50 Raise Levee Embankment with Curb Wall. This section will require shallow excavation for installation of the curb wall. Proposed curb wall is approximately 3 feet from the existing asphalt pavement and will be 18 inches high by 6 inches wide. A guard rail will be installed for full length of curb wall. See Sheets C-103 and C-104 in Appendix A for more details. 55+70 to 56+90 Widen Levee Embankment with Retaining Wall. Excavation landward of the existing floodwall approximately 20 feet wide and several feet deep to install a 4-inch-thick layer of base coarse material prior to construction of the Mechanically Stabilized Earth (MSE) retaining wall. The MSE is 11 inches wide and approximately 3 feet tall. See Sheets C-105, C-106 and C-107 in Appendix A for more details. 58+10 to 59+85 Construct Floodwall, Reconstruct Damaged Floodwall and Raise Levee Embankment. A new floodwall will be installed adjacent to the sidewalk. The existing damaged floodwall will be reconstructed and raised with cast-in-place concrete. The existing adjacent embankment will also be raised. The floodwall and embankment activities will require shallow excavation. See Sheets C-109 and C-110 in Appendix A for more details. 2.2. Construction Schedule and Sequence Currently, construction of the project is scheduled to start in summer 2022, pending CLOMR approval and receipt of applicable environmental permits. Construction is anticipated to take approximately 2 years to complete, tentatively concluding in summer 2024. It should be noted that the project schedule is only a likely representation of what the actual schedule may be and variations in work timing and possible phasing February 16, 2022 | Page 4 File No. 0693-078-01 may occur due to funding, contractor delays or adverse weather conditions. A generalized construction schedule at each improvement location follows: ■ Install temporary erosion and sediment control (TESC) measures and construction best management practices (BMPs) ■ Clearing and grubbing ■ Stripping and excavation/sawcut ■ Compacted fill/base course ■ Install wall footings (if applicable) ■ Fill and compact earthen embankments to meet freeboard requirement (if applicable) ■ Install curbs/walls or raise walls (if applicable) ■ Levee overbuild/regrading ■ Concrete/asphalt paving and other site restoration ■ Landscaping/replanting and associated habitat mitigation 2.3. Impact and Minimization Measures 2.3.1. Best Management Practices (BMPs) Conservation measures and BMPs will be employed during construction activities to avoid impacts to listed species and their habitat. Conservation measures will focus on: (1) constructing the levee outside the ordinary high water mark (OHWM); (2) managing stormwater quality (see below); (3) minimizing construction noise; and (4) reducing the possibility of spills, preventing soil erosion and minimizing impacts to vegetation. Special measures will be taken to ensure that generated waste materials requiring disposal (such as construction debris, and land clearing debris) will be disposed of off-site and in accordance with applicable regulations. Adequate materials and procedures will be readily available on the site to respond to unanticipated weather conditions or accidental releases of materials, and a protocol for contacting Washington Department of Fish and Wildlife (WDFW) will be readily available in the event that activities are observed to result in fish kills, fish in distress or other water quality problems. 2.3.2. General Conservation Measures ■ The TESC plan will be fully implemented as part of a Stormwater Pollution Prevention Plan (SWPPP). Construction techniques will utilize BMPs such as those described in the most recent version of Washington State Department of Transportation’s (WSDOT) Standards and Specifications for Road, Bridge, and Municipal Construction (WSDOT 2021) and Washington State Department of Ecology’s (Ecology) Stormwater Management Manual for Western Washington (Ecology 2019), and as required by the City stormwater code. Appropriate erosion control measures will be erected at appropriate locations according to the SWPPP. ■ The contractor will prepare a Spill Prevention, Control and Countermeasures (SPCC) Plan for this project. Spills will be handled and disposed of in a manner that does not contaminate the surrounding area. Adequate materials and procedures to respond to unanticipated weather conditions or accidental releases of materials (sediment, petroleum hydrocarbons, etc.) will be available on site. The SPCC Plan will also ensure the proper management of oil, gasoline and solvents used in the operation and February 16, 2022 | Page 5 File No. 0693-078-01 maintenance of construction equipment and that equipment remains free of external petroleum-based products prior to entering the work area and during the work, and for making necessary repairs prior to returning the equipment to operation in the work area. ■ An emergency spill containment kit must be located on site along with a pollution prevention plan detailing planned fueling, materials storage and equipment storage. Waste storage areas must be prepared to address prevention and cleanup of accidental spills. ■ Construction-related debris within riparian/shoreline areas (200 feet from waterbodies) will be cleaned up daily. Proper conservation measures will be taken to ensure that debris will not contaminate critical areas. ■ Waste materials, including concrete, riprap, miscellaneous garbage and/or other debris removed from the project site, will be transported off-site for disposal in accordance with applicable regulations. ■ Work will follow other local, state and federal regulations and restrictions. ■ Within riparian/shoreline areas, excavation will be limited to those areas necessary for access to the work areas and construction activities. The construction limits will be marked in the field and equipment will not be allowed outside the work area. ■ Adequate materials will be maintained on site to respond to weather conditions and modify the construction plan as needed to accommodate unanticipated events. ■ Routine inspections of the erosion control measures will be conducted daily to ensure the effectiveness of the measures and to identify the need for maintenance or additional control measures. ■ Grading and construction will be phased to reduce the time that soil is exposed to the extent possible. ■ Silt fences will be constructed around excavation areas that are within the riparian/shoreline zone. ■ Spoil stockpiles within the riparian/shoreline zone will be contained using BMPs to reduce the potential for introduction of fine sediments into adjacent waters. ■ Disturbed slopes will be hydroseeded following project completion. ■ Disturbance will be limited to the smallest area feasible for each phase of the project and element under construction and will stay within the limits of construction as identified on the site plans. ■ Fueling areas will be distinctly identified and established outside of riparian/shoreline zones, but within the construction area. These areas will be equipped with spill prevention and control devices. 2.3.3. Additional Measures to Reduce Impacts to Species and Habitats Specific conservation measures and BMPs to minimize impacts to species and habitats could include but are not limited to: ■ There will be no work below the OHWM of waterbodies under state or federal jurisdiction. ■ The project will obtain and comply with conditions that will be outlined in state and federal permits. ■ Debris resulting from construction within the riparian/shoreline zone shall be removed from the project area and prevented from entering the river. ■ Construction procedures within riparian/shoreline areas have been designed to minimize the opportunity for erosion to occur or sediment-laden water to enter downstream areas. February 16, 2022 | Page 6 File No. 0693-078-01 ■ Depending on slope and weather conditions, sediment laden run-off will be managed with appropriate stormwater BMPs such as silt fences, sediment traps and other approved measured. 3.0 ACTION AREA The Action Area is defined as “all areas to be affected directly or indirectly by the federal action and not merely the immediate area involved in the action” (50 Code of Federal Regulations [CFR] §402-02). The Action Area, therefore, includes the spatial extent of direct and indirect effects, as well as effects of interrelated and interdependent activities of the project. Many project effects are temporary in nature, occurring during or immediately after construction; other project effects may persist after project completion as a result of long-term changes to the environment. For this project, the Action Area was identified as the footprint of the levee improvements as well as the surrounding area within which noise effects will extend (which varies depending on levee construction type) above land and water surfaces, as shown on Figure 2, Cedar River Section 205 Levee System Vicinity Map and Action Area. The Action Area includes upland and riparian but does not include any aquatic habitats as no work will be performed below the OHWM and no effects of the project generated in upland locations are anticipated to extend below the OHWM. Project-specific effects that were considered to identify the Action Area for the project include: ■ Operation of construction equipment (direct effect, short-term temporary impact); ■ Construction-related noise (direct effect, short-term temporary impact); ■ Degradation of water quality (direct effect, short-term impact); and ■ Habitat alteration (direct and indirect effects, potential for both short-term and long-term impacts). The spatial extents of these effects were used to identify the Action Area, as discussed in the following sections. 3.1. Operation of Construction Equipment During construction of the levee repairs, equipment will operate in natural habitat areas potentially utilized by terrestrial species. There will be no in-water work within the Cedar River as part of this project. Species occupying terrestrial forested or other vegetated areas, if present, could be affected as a result of interaction with construction equipment and/or construction materials. 3.2. Construction-Related Noise Construction-related noise will occur as a result of operation of general construction equipment. This effect is limited to the construction period and will not persist once construction is complete. Construction-related noise will permeate terrestrial (in-air) environments and may carry into the surrounding environment beyond the project site. Construction-related noise will not affect aquatic (underwater) environments because construction will occur above OHWM. The extent that in-air noise will permeate the surrounding environment was estimated using guidance provided by WSDOT (2020). These activities will require the use of heavy machinery. Heavy machinery includes earth-moving equipment such as excavators, front end loaders, haul trucks and other equipment. February 16, 2022 | Page 7 File No. 0693-078-01 Excavator, concrete saw and paving equipment are the three loudest pieces of equipment to be used at the site, both the excavator and the concrete saw generate 85 decibles A (dBA) and the paving equipment generates 82 dBA, at a distance of 50 feet (WSDOT 2020). Due to the possibility of all three pieces of machinery being operated simultaneously, the rule of decibel addition provided in the WSDOT BA Manual (WSDOT 2020) was applied to the construction noise assessment. Based on this analysis, construction noise is estimated to be up to 89 dBA if all of these pieces of equipment are run simultaneously. The project area is located adjacent to Renton Municipal Airport. The WSDOT BA Manual (2020) identifies jet takeoff to generate noise levels of up to 120 dBA at a distance of 200 feet and regular noise intrusions from traffic and aircraft overflights to generate noise levels between 45 and 72 dBA. This site is immediately adjacent to the airport and surrounded by heavy urban traffic; therefore, a relatively conservative noise level of 70 dBA was selected for ambient background noise at the site. Although there is a narrow riparian buffer (more significant on the east bank) and some grassy areas on both sides of the river, the project surroundings are generally dominated by buildings, paved surfaces and water (Cedar River and Lake Washington), creating a “hard site” condition as defined for the purposes of estimating noise level attenuation (WSDOT 2020). Based on the noise level from the loudest pieces of equipment (89 dBA) and attenuation calculated by the equation provided in the WSDOT BA Manual (WSDOT 2020) with “hard site” conditions, the distance from the project site at which the loudest equipment would become indistinguishable from background in-air, ambient noise conditions (i.e., 70 dBA) is approximately 446 feet. 3.3. Water Quality The project is expected to have minimal impact to water quality of the Cedar River, since there is no in- water work and the application of construction stormwater BMPs and spill prevention activities. In the event of failure of these protective measures, there is a potential for impact to river water quality from sediment erosion, spilling hazardous materials or release of petroleum-based products during construction. This potential is limited to the construction period and would not have lasting impacts once construction is complete. The potential for sediment erosion and spills will be controlled through proper implementation of BMPs. The project does not have the potential to impact water quality indirectly as a result of long-term changes because there will be no new pollution-generating impervious surfaces (PGIS) resulting from this project and there will be no long-term change to the discharge volume and treatment of stormwater. The zone of influence in which water quality could be temporarily impacted because of spills or other construction-related degradation is limited to the Cedar River which is immediately adjacent to the project construction footprint. 3.4. Habitat Alteration Habitat alteration may result from direct impacts to riparian vegetation from levee improvement construction, as well as indirect changes in flood storage capacity, availability of refuge habitat and habitat forming processes. Direct effects (impacts to vegetation) and indirect effects (impacts to other floodplain habitats and processes) are discussed separately in the following sections. Alteration of stream habitats is not anticipated. February 16, 2022 | Page 8 File No. 0693-078-01 3.4.1. Riparian Vegetation Impacts to riparian vegetation within the Protected Area will be limited. Where the levee alignment is immediately adjacent to the river, the concrete floodwall will generally be constructed at the immediate edge of existing road infrastructure, thereby minimizing impacts to riparian vegetation. There will be approximately 12,000 square feet of temporary impacts and 1,200 square feet of permanent impacts to shrubs and turf grass due to construction. The existing riparian vegetation that will be affected is mostly comprised of turf grass, invasive shrubs and ornamental landscape shrubs, with some native shrub areas being temporarily affected as well (but no native shrub areas permanently removed). A total of nine native trees will be removed as well from within the riparian vegetation conservation buffer. In-kind mitigation for riparian buffer impacts is proposed through a combination of the following: ■ Restoring all temporarily impacted areas with vegetation equal in habitat value or better than what was temporarily removed. For example, turf grass will typically be replaced with turf grass, landscape and invasive shrubs will be replaced with native shrubs and native shrubs will also be replaced with native shrubs. ■ Removal of invasive vegetation and installation of native plants in additional compensatory riparian mitigation areas to offset permanent impacts to invasive shrub communities. Compensatory riparian mitigation areas are located within the project reach to provide on-site improvement of ecological functions. ■ Replacement of native trees removed at a ratio exceeding 2:1 within the replanted areas. Details regarding riparian vegetation mitigation are provided in the Riparian Habitat Mitigation Plan (GeoEngineers 2021) and the riparian planting plan is included in Appendix A. The zone of influence for potential alteration of riparian habitats is limited to areas directly impacted by construction activity, which is defined as the construction footprint, including the compensatory mitigation areas that will be cleared of invasive species and planted with native riparian vegetation as mitigation for the project. 3.4.2. Floodplain Habitats and Processes The zone of influence for potential alteration of floodplain habitats and processes is limited to undeveloped habitat areas within the levee improvement construction footprint as well as landward of where the levee improvements will be constructed. This zone includes minimal undeveloped riparian vegetation as well as some turf grass areas associated with the Senior Activities Center and the Renton Municipal Airport. These areas may extend some distance from the levee and/or river, but all occur within the same zone of influence identified for noise above. 3.5. Action Area Summary The overall Action Area includes the spatial extent of all project effects on the environment and is presented in Figure 2. Because of the construction sequencing and the planned BMPs, stormwater and debris will largely be contained within the project limits; therefore, the in-air noise effects from construction activities will extend the furthest (446 feet) and set the boundary for the Action Area, which will define the limits of analyses for effects on species and habitats. February 16, 2022 | Page 9 File No. 0693-078-01 4.0 SPECIES AND HABITAT INFORMATION Species listed under the ESA fall under the jurisdiction of one of two federal agencies: the U.S Fish and Wildlife Service (USFWS) for terrestrial and freshwater species, and the National Marine Fisheries Service (NMFS) for marine species. A list of the listed or proposed species and designated or proposed critical habitat for the project area was obtained from the USFWS (2021a; 2021b). Lists of the listed or proposed species and designated or proposed critical habitat for marine species in the Puget Sound were also obtained from NOAA Fisheries/NMFS (NOAA Fisheries 2021). These official species lists and critical habitat maps are included in Appendix B, Species Lists. According to WDFW Priority Habitats and Species (PHS) data and USFWS Information for Planning and Consultation (IPaC) data, the project site potentially contains numerous fish species. Washington State Department of Natural Resources (DNR) shows no sensitive plant records in the vicinity of the project (DNR 2020). 4.1. Species and Critical Habitat that May be Present in the Action Area The USFWS and NMFS lists identify species and critical habitat potentially present within the Action Area based on regional distribution. Consequently, not all species on these lists are expected to occur within the Action Area based on actual habitat conditions and occurrences. Information regarding the presence of listed species within the Action Area was obtained from the WDFW PHS online mapper (WDFW 2021a) and USFWS IPaC (USFWS 2020). A summary of listed species and critical habitat status found in the Action Area is listed in Table 2. TABLE 2. ESA SPECIES AND CRITICAL HABITAT THAT MAY OCCUR IN THE ACTION AREA Common Name Specific Name Status Jurisdiction Critical Habitat Presence1 Gray wolf Canis lupus Proposed Endangered USFWS N/A North American wolverine Gulo gulo luscus Proposed Threatened USFWS N/A Marbled murrelet Brachyramphus marmoratus Threatened USFWS No Streaked horned lark Eremophila alpestris strigata Threatened USFWS No Yellow-billed cuckoo Coccyzus americanus Threatened USFWS No Chinook Salmon Oncorhynchus tshawytscha Threatened NMFS Yes Steelhead Oncorhynchus mykiss Threatened NMFS Yes Bull trout Salvelinus confluentus Threatened USFWS No Notes 1. Critical habitat listings are as follows: Yes indicates that critical habitat occurs in within the Action Area; No indicates that critical habitat for the species has been designated but it does not occur within the Action Area; N/A indicates that critical habitat has not been designated or proposed for the species. February 16, 2022 | Page 10 File No. 0693-078-01 4.2. Species and Critical Habitat Not Addressed in the Biological Evaluation The following is a list of species and critical habitat that are not addressed further in this report due to lack of suitable habitat in the Action Area: ■ Gray wolf (Canis lupus). Gray wolves are wide ranging and will occupy a variety of habitat types with no apparent preference for one type or another. They tend to be present in areas with few roads, low human presence and abundant prey bases. A minimum of approximately 4,000 to 5,000 square miles of contiguous habitat with low road density may be required to support a viable population. Gray wolves are reported to be rare in Washington and they are considered critically imperiled (i.e., at very high risk of extinction because of extreme rarity, very steep declines or other factors) (NatureServe 2021). PHS data does not indicate their presence in the Action Area (WDFW 2021a). The Action Area does not contain habitat for this species due to the lack of suitable forested areas and the presence of urban human activities. Therefore, gray wolves are not expected to occur in the Action Area. ■ North American Wolverine (Gulo gulo luscus). There are no known North American Wolverines inhabiting Renton. Wolverines are not expected to occur in the urban environment of the City. The likelihood of a wolverine entering the Action Area is minimal to none. ■ Marbled murrelet (Brachyramphus marmoratus). Marbled murrelet foraging occurs in marine waters and nesting occurs in old growth and mature forests. The closest designated critical habitat for the marbled murrelet occurs approximately 30 miles east of the Action Area for the project (USFWS 2021b). The Action Area does not contain habitat for this species due to the lack of marine foraging areas or old growth forest nesting areas. Therefore, marbled murrelets are not expected to occur in the Action Area. ■ Streaked Horned Lark (Eremophila alpestris strigata). This species typically utilizes open spaces dominated by grasses and other herbaceous vegetation (Stinson 2005). The adjacent Renton Municipal Airport partially meets these habitat needs but consists of predominantly asphalted surfaces and is surrounded by urban development. Although airports typically provided suitable habitat for this species, there are no populations identified at the Renton Municipal Airport (Stinson 2016). Therefore, streaked horned larks are not expected to be within the project area. ■ Yellow-billed cuckoo (Coccyzus americanus). Yellow-billed cuckoos are associated with open deciduous woodlands and deciduous forests that are at least 25 acres in size (NatureServe 2021). Yellow-billed cuckoos are not expected to occur in the developed riverine and shoreline environment where there are limited forested areas. The likelihood of a yellow-billed cuckoo entering the Action Area is minimal to none. 4.3. Utilization of Habitats by Listed Species Terrestrial habitats surrounding the project site are influenced by urban development. Vegetation within the riparian zone along this stretch of the Cedar River is comprised of a mix of: mature native trees and shrubs; recently planted native trees, shrubs and herbaceous species that were installed as mitigation for the 2016 maintenance dredging cycle; park landscaping, including ornamental trees, shrubs and mowed grasses; unmaintained grass areas; and sections dominated by invasive species. Aquatic habitats adjacent to the levees is highly modified as a result of the history of channel modification including the re-alignment of the lower Cedar River, as well as recurring dredging. The lower Cedar River through the project area is a straightened channel with floodwalls and levee embankements on either side, February 16, 2022 | Page 11 File No. 0693-078-01 bank armoring in places, and several bridges. Dredging of this section of river has been implemented repeatedly since the channel was constructed at the time the Cedar River was diverted from its original alignment into the Black River and Duwamish Channel to Lake Washington instead. The river was last dredged in 2016 and in 1998 before that. Recent mitigation has included removal of some hard bank armoring in favor of “soft” bioengineered bank stabilization methods, as well as other efforts to reduce the impacts of human alteration on rivering conditions. 4.3.1. Chinook Salmon The Puget Sound evolutionarily significant unit (ESU) for Chinook Salmon includes those stocks in tributaries of Puget Sound westward to the Elwha River. Spawning occurs in late summer and fall. The Cedar River is known to contain a native stock of Chinook Salmon with wild reproduction (USFWS 2011, WDFW 2021b, WDFW 2019). The Cedar River is a high priority area because it includes spawning areas higher up in the watershed (upstream from the project reach) and rearing areas, which occur downstream to the mouth of the river at Lake Washington, including the project reach (WRIA 8 2017). Recent data collected from a screw trap located upstream of the project reach, where Interstate 405 crosses the Cedar River, indicates 31,804 natural-origin Chinook parr emigrated into Lake Washington from the Cedar River during 2018, with a peak in early March (Lisi 2019). Therefore, Chinook Salmon are expected to occur seasonally in the Cedar River within the Action Area. 4.3.2. Steelhead The Puget Sound distinct population segment (DPS) of Steelhead includes winter- and summer-run Steelhead in the river basins of the Strait of Juan de Fuca, Puget Sound and Hood Canal, Washington, bounded to the west by the Elhwa River and to the north by the Nooksack River and Dakota Creek, both of which are included in the DPS (72 FR 26722). The Cedar River is known to support a native stock of winter Steelhead with wild reproduction (Cram et al 2018). As with Chinook, Steelhead spawning typically occurs upstream of the project reach; however, the project reach of the Cedar River is documented to provide year- round winter Steelhead rearing habitat (WDFW 2021a; 2021b). Therefore, Puget Sound Steelhead are expected to occur in the Cedar River within the Action Area. 4.3.3. Bull Trout Coastal/Puget Sound DPS Bull Trout occur within marine areas and freshwater streams of King County (75 FR 63897-64070). Native Bull Trout are present in some reaches of the Cedar River and in Lake Washington (WDFW 2021a; 2021b). Consequently, Bull Trout may occur in the Cedar River within the Action Area and are therefore addressed in this BA. Critical habitat for Bull Trout is not designated within the Action Area and is therefore not addressed. 4.3.4. Primary Constituent Elements of Salmon and Steelhead Critical Habitat The Cedar River is designated critical habitat for Chinook Salmon and Steelhead. Primary Constituent Elements (PCEs) for Chinook Salmon (70 FR 52630-52853) and Steelhead (81 FR 9252-9325) include: 1. Freshwater spawning sites with water quantity and quality conditions and substrate supporting spawning, incubation and larval development; 2. Freshwater rearing sites with water quantity and floodplain connectivity to form and maintain physical habitat conditions and support juvenile growth and mobility; water quality and forage supporting juvenile development; and natural cover such as shade, submerged and overhanging large wood, log February 16, 2022 | Page 12 File No. 0693-078-01 jams and beaver dams, aquatic vegetation, large rocks and boulders, side channels and undercut banks; 3. Freshwater migration corridors free of obstruction with water quantity and quality conditions and natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulders, side channels, and undercut banks supporting juvenile and adult mobility and survival; 4. Estuarine areas free of obstruction with water quality, water quantity and salinity conditions supporting juvenile and adult physiological transitions between fresh and saltwater; natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulders, and side channels; and juvenile and adult forage, including aquatic invertebrates and fishes, supporting growth and maturation; 5. Near-shore marine areas free of obstruction with water quality and quantity conditions and forage, including aquatic invertebrates and fishes, supporting growth and maturation; and natural cover such as submerged and overhanging large wood, aquatic vegetation, large rocks and boulders, and side channels; and 6. Offshore marine areas with water quality conditions and forage, including aquatic invertebrates and fishes, supporting growth and maturation. The project Action Area includes freshwater specific PCEs (PCEs 2 and 3) for both Chinook Salmon and Steelhead. PCE 1 (spawning sites) typically do not occur in the Action Area and are located further upstream in the watershed for both species. In-stream habitat within Action Area supports rearing and migration for Chinook Salmon and Steelhead, as well as other salmon species. The project site does not contain marine areas; therefore, PCEs 4, 5 and 6 are not present within the Action Area. 4.4. Occurrence Summary As described in Section 6.1 Operation of Construction Equipment and Section 6.2, Construction-Related Noise, some of the listed and proposed species and critical habitat that occur in King County are not expected to occur in the Action Area and are therefore not addressed in the remainder of this BA. The project will have no effect on the following species and critical habitat: ■ Gray wolf ■ North American wolverine ■ Marbled murrelet (including critical habitat) ■ Streaked horned lark (including critical habitat) ■ Yellow-billed cuckoo (including critical habitat) ■ Designated critical habitat for Bull Trout February 16, 2022 | Page 13 File No. 0693-078-01 5.0 ENVIRONMENTAL BASELINE Land use surrounding the project reach and Action Area, including some of the terrestrial portions of the Action Area, includes predominantly commercial and industrial development, as well as a narrow corridor of recreational park and riparian habitat on the right bank of the river, as well as on the left bank upstream (south) of Logan Avenue. 5.1. Terrestrial Habitat 5.1.1. Topography The upland topography in the project area is generally flat with some short steep banks along the Cedar River. The river banks in the project reach are armored in most areas with riprap and/or concrete and include slopes as steep as approximately a 2H:1V (Horizontal:Vertical) slope in some locations. 5.1.2. Vegetation Terrestrial habitat conditions within the project corridor are generally degraded and consist primarily of a narrow strip of riparian vegetation constrained by adjacent development, with high densities of invasive species. Vegetation within the project reach includes relatively mature trees and large shrubs, such as red alder, Pacific willow, Sitka willow and black cottonwood as well as recent native shrub plantings that have yet to mature. Invasive species management is being implemented by the City of Renton for areas that were previously designated as mitigation for the 2016 maintenance dredging cycle. Other areas continue to harbor invasive species communities including Japanese knotweed, reed canarygrass, Himalayan blackberry and Scotch broom. The Cedar River Trail Park is located immediately adjacent to the east bank of the Cedar River within the project reach. Cedar Triver Trail Park is maintained with extensive grass lawn areas, ornamental trees and manicured shrubs. 5.1.3. Suitable Habitat The Action Area does not contain suitable habitat for listed terrestrial species due to the high level of urban development and the lack of forested areas. Therefore, terrestrial species are not discussed further in this assessment. Terrestrial riparian vegetation performs a critical role in maintaining suitable habitat for salmonids in adjacent aquatic habitat. Native trees and shrubs within the riparian buffer provide: shade to the aquatic system, reducing water temperatures; nutrient inputs such as organic detritus; habitat supporting macroinvertebrate communities; and contribute large woody material (LWM) that increases habitat heterogeneity and encourages habitat-forming riverine processes, among other functions. Although salmon do not directly occupy terrestrial areas, condition of the terrestrial riparian vegetation adjacent to the river plays an important role in maintaining healthy aquatic habitat for salmon. 5.2. Freshwater Aquatic Habitat The Cedar River is a major tributary of Lake Washington providing approximately 57 percent of the flow into the lake. Cedar River is part of Washington State WRIA 8 – Cedar/Sammamish. Most of the lower Cedar River basin is rural and forested, with the exception of the cities of Renton and Maple Valley, which are heavily urbanized (Kerwin 2001). The lower Cedar River basin contains 60 percent forested land cover, 29 percent low- to medium-density development and 0.9 percent high-density development (King County 1997). The project reach of the Cedar River was diverted from the Green/Duwamish River system February 16, 2022 | Page 14 File No. 0693-078-01 into Lake Washington in 1912. This has resulted in the need for 64 percent of the lower Cedar River to have levees or revetments along at least one of the banks (Kerwin 2001). The lower reach of the Cedar River also requires recurrent maintenance dredging to remove sediment deposition and maintain flood flow conveyance while protecting adjacent infrastructure from flood damage. 5.2.1. General Aquatic Conditions The project reach of the Cedar River was artificially constructed when the Cedar River was diverted into Lake Washington and is constrained by levees and revetments. The project reach is linear and channelized, with limited habitat complexity. The river banks in this area are armored with riprap and/or retaining walls in some places, though recent efforts to remove hard armoring in favor of soft solutions have been implemented in some places during the prior 2016 maintenance dredge cycle. Through the project reach, the Cedar River is completely disconnected from its historic floodplain and off-channel habitat is mostly lacking. The low gradient within the project reach contributes to sediment loading (Kerwin 2001). River substrate is primarily composed of gravel with cobbles, sand and a very small fraction of silt. Dredging is necessary within this reach of the river to reduce flooding caused by sediment deposition. Riparian conditions are mixed within the Action Area. The Renton Municipal Airport is located immediately adjacent to the project on the left (west) bank. The right (east) bank of the river contains a riverfront park with managed lawn grasses, trees and shrubs. Beyond the park to the east is the Renton Boeing Facility. Development along the banks of the river has limited the riparian corridor to a small strip on either side of the river containing a mix of invasive and native plant species, which has been the subject of prior mitigation to offset the impacts of dredging. Three bridges cross the Cedar River in the project reach, contributing to interruption of the riparian buffer and overwater shading with static hard edges. 5.2.2. Suitable Habitat Although this portion of the Cedar River is highly altered and degraded, the project reach provides suitable migratory habitat and limited rearing habitat for anadromous salmonids, including documented use by Chinook Salmon and Steelhead as they migrate further upstream to suitable spawning reaches and downstream during outmigration toward the ocean. Bull Trout have been documented in Lake Washington but rarely in the Cedar River and they have not been observed in the WDFW trap in the lower river over the past 20 years. 6.0 ANALYSIS OF EFFECTS ON SPECIES AND HABITAT This section provides analysis of the effects the project is likely to have on Chinook Salmon, Steelhead and Bull Trout within the Action Area. Direct effects include all impacts directly associated with project implementation and construction activities as well as any disturbances that would occur very close to the time of construction. Indirect effects are those that could result from the project, but occur later in time. For this project, direct effects include: operation of construction equipment, construction-related noise, habitat alteration adjacent to the Cedar River and construction-related impacts to water quality. Indirect effects are related to the impact on food web dynamics and prey resources from removal of vegetation. Project-related direct and indirect effects on species and habitat are discussed in the following sections. February 16, 2022 | Page 15 File No. 0693-078-01 6.1. Operation of Construction Equipment As described in Section 3.0 Action Area, construction equipment will operate in upland locations near the banks of the river (riparian areas) in order to complete levee improvements. If ESA-listed species occur within the areas where construction equipment is operating, there could be a direct interaction resulting in harm or harassment. However, as presented in Section 4.2 Species and Critical Habitat Not Addessed in the Biological Evaluation, there are no ESA-listed terrestrial species or suitable habitat within the Action Area. As a result, operation of construction equipment will not affect listed terrestrial species. Likewise, listed salmonids including Chinook Salmon, Steelhead and potentially Bull Trout, could be present within the Cedar River channel. Since construction equipment will not operate below the OHWM, construction equipment will not directly affect listed fish species present in the Action Area. 6.2. Construction-Related Noise In-air construction noise may permeate terrestrial environments up to approximately 446 feet from the project area due to use of construction machinery that generates noise in excess of baseline conditions extending into the surrounding environment. Since there are no terrestrial ESA-listed species within the Action Area, in-air construction-related noise effects are non-existent. Equipment will not operate below the OHWM and therefore no in-water noise impacts will occur as part of this project. Therefore, construction- related noise will not affect listed fish species either. 6.3. Habitat Alteration 6.3.1. Riparian Habitat Temporary alteration of riparian habitat associated with the Cedar River is anticipated to result from construction of proposed levee improvements. Temporary habitat alteration consists of disturbance of turf grass and shrub communities, which will be removed during construction and subsequently restored. Vegetation that will be removed is primarily invasive or lacking in habitat function (e.g., manicured landscape shrubs and turf grass). However, in some areas, native shrubs will be affected. In a few locations, alteration of riparian habitat, including some tree removals, is permanent, due to either (1) displacement of the existing habitat by levee infrastructure, and/or (2) restrictions on replanting/restoring affected areas due to levee vegetation standards or the occurrence of underground utilities. GeoEngineers has developed a riparian habitat mitigation plan to document impacts to riparian habitat and associated mitigation (GeoEngineers 2021). Temporarily impacted areas will be restored with an equivalent or more functional habitat type than what is removed. For example, turf grass areas will typically be replaced with turf grass, landscaping shrubs will be replaced with native shrubs and invasive species communities will be replaced with native trees and shrubs. Permanently impacted areas will either be replaced with a lower functioning habitat type, for example where levee vegetation standards restrict the ability to replant trees, or will be completely displaced by proposed improvements. Permanent impacts are extremely limited for this project and will be mitigated using adjacent on-site compensatory mitigation, as documented in the Mitigation Plan. Native communities installed as restoration and compensatory mitigation, once established, are expected to provide greater levels of riparian function than existing communities they replace. Restoration and mitigation plantings will specify fast-growing species that are anticipated to become established within February 16, 2022 | Page 16 File No. 0693-078-01 1 to 2 years. However, there will still be a short-term temporal loss of functions that riparian vegetation provides during and immediately after construction work, which is accounted for by proposing mitigation ratios that exceed 1:1. Therefore, the net effects of vegetation impacts and restoration/mitigation are expected to be similar to or slightly beneficial with regard to habitat conditions relative to baseline conditions. Increasing riparian vegetation along the river banks will create overwater shading and increase invertebrate habitat along the margins of the river. These effects will improve habitat quality and quantity as well as increase food sources for salmonids. With implementation of appropriate site restoration and compensatory habitat mitigation, the short-term effects on riparian vegetation cover are considered insignificant. Because affected riparian habitat will be replaced with native communities that exceed the functional value of baseline conditions in some places, these actions will result in long-term beneficial effects. 6.3.2. Food Web Dynamics and Prey Resources Temporal loss of riparian vegetation is considered an indirect effect to short-term reductions of allocthonous inputs that may provide prey sources or support other prey resources. Because the project is in the lowest reach of the Cedar River, with ample source populations of benthic invertebrates immediately upstream that would be transported naturally into the reach, and most vegetation impacts are not immediately adjacent to the river, quantity of prey resources are not anticipated to be impacted by project actions. Loss of riparian habitat will be very limited, occurring primarily in areas dominated by invasive vegetation, and will be restored and/or mitigated as part of the project. Once restored plantings mature, they will replace this short term reduction in inputs. Therefore, this effect is anticipated to be insignificant. 6.3.3. Floodplain Habitat Functions The project will permanently increase the level of flood protection provided by the levee system. Consequently, there is potential for adverse impacts on floodplain habitat functions, such as flood storage capacity and refuge from high velocity flows, that are important to fish, particularly during times of high river discharge and/or flooding. With levee improvements, the level of isolation of the historic floodplain from the primary channel of the river will be maintained and/or increased. However, it should be noted that: (a) the historic floodplain adjacent to the project reach is highly developed and previously degraded from providing habitat functions; and (b) the levee system already isolates the historic floodplain from flows exceeding the 100-year recurrence interval flood – proposed improvements generally increase the freeboard requirement and therefore will not have a substantive effect on the level of floodplain isolation. Therefore, potential areas that could be isolated by the levee system provide limited habitat function and are already isolated at all but the most extreme flow levels due to prior topographic alterations and initial installation of the levee system, therefore rendering this effect discountable. Habitat-forming process, such as contribution of LWM, may be affected only to the extent there is alteration to the riparian vegetation community. Tree removals are limited and will be mitigated by planting replacement trees at an increased ratio. There will be no bank armoring or other bank alterations associated with the project. Spawning habitat for ESA-listed species does not occur within the Action Area and rearing or migratory habitats within the river will not be directly altered by the project because there will be no work below the OHWM. Therefore, there are no anticipated changes to habitat-forming processes that will result from the project. February 16, 2022 | Page 17 File No. 0693-078-01 6.4. Impacts to Water Quality Potential water quality impacts that could occur in the Cedar River during construction are anticipated to be limited to construction stormwater runoff associated with upland construction work adjacent to the river. Increased turbidity within the Cedar River is not anticipated with proper implementation of BMPs that will control and minimize transport of fine sediments off-site during construction. These BMP measures will include developing and implementing a TESC plan as part of the SWPPP. Therefore, effects of turbidity on critical habitat are considered discountable. 6.5. Interrelated and Interdependent Actions Interrelated actions are those that are part of a larger action and depend on the larger action for their justification. Interdependent actions are those that have no independent utility apart from the action being considered. There are no interdependent or interrelated actions associated with the proposed project. 7.0 EFFECT DETERMINATIONS Based on the analysis of effects presented in Section 6.0 Analysis of Effects on Species and Habitat, we have made effect determinations for each listed species and designated or proposed critical habitat that may occur in the Action Area. Effects determinations take into account all of the possible project effects; our determinations are summarized in Table 3 and discussed below. TABLE 3. EFFECT DETERMINATIONS FOR LISTED AND PROPOSED SPECIES Common Name Federal Status Jurisdiction Effect Determination for Species Effect Determination for Critical Habitat Chinook Salmon Threatened NMFS NLTAA NLTAA Steelhead trout Threatened NMFS NLTAA NLTAA Bull Trout Threatened USFWS NLTAA N/A Notes: NLTAA = Not Likely to Adversely Affect 7.1. Chinook Salmon and Steelhead The project may affect Chinook Salmon and Steelhead because: ■ Suitable habitat for these species is present in the Cedar River within the Action Area, and they have been documented to utilize the river as a migratory corridor and rearing area within the Action Area. ■ Project construction activities will alter riparian habitat and potentially generate turbidity, temporarily degrading water quality in the Cedar River. The project is not likely to adversely affect Chinook Salmon and Steelhead because: ■ Construction equipment will not operate within the water in potentially occupied habitat. ■ Construction-related noise will not permeate underwater environments. ■ Impacted riparian habitat will be restored and/or mitigated following construction. February 16, 2022 | Page 18 File No. 0693-078-01 ■ Construction activities will incorporate BMPs to minimize turbidity impacts from stormwater. The project may affect designated critical habitat for Chinook Salmon and Steelhead because: ■ The Action Area includes portions of the Cedar River and associated riparian buffer that are designated as Critical Habitat for these species. ■ Construction will involve removal of vegetation within the riparian buffer of the Cedar River. The project is not likely to adversely affect designated critical habitat for Chinook Salmon and Steelhead because: ■ Temporary impacts to riparian habitat predominantly affect invasive species communities or other low value habitat (mowed grass, landscape shrubs); temporarily affected vegetation will be restored following construction with replacement plantings of an equal or better habitat functional value. ■ Permanent alteration of riparian habitat adjacent to the Cedar River, either by degrading habitat that will not be able to be restored or fully displacing habitat, will be mitigated through adjacent riparian habitat enhancements, resulting in no net loss of riparian habitat function. ■ The project will have no impacts on in-stream habitat. 7.2. Bull Trout The project may affect Bull Trout because: ■ Suitable habitat for Bull Trout is present in Lake Washington, which is hydrologically connected to portions of the Cedar River within the Action Area; there are no barriers preventing Bull Trout from entering the project reach of the Cedar River. ■ Project construction activities will alter riparian habitat and potentially generate turbidity, temporarily degrading water quality in the Cedar River. The project is not likely to adversely affect Bull Trout because: ■ Bull trout have not been documented to use portions of the Cedar River within the Action Area; the chance of occurrence of Bull Trout is considered discountable, and therefore, alteration of riparian habitat (the effects of which are insignificant) and potential construction-related elevated turbidity (which is discountable itself) are not anticipated to impact this species. 8.0 ESSENTIAL FISH HABITAT EVALUATION The MSA, as amended by the Sustainable Fisheries Act of 1996 (Public Law 104-267), includes a mandate that NMFS must identify EFH for federally managed marine fish, and federal agencies must consult with NMFS on activities that may adversely affect EFH. The Pacific Fisheries Management Council has designated EFH for the Pacific salmon fishery, and federally managed groundfish and coastal pelagic fisheries. The objective of the EFH assessment is to describe potential adverse effects to designated EFH for federally managed fisheries species within the proposed Action Area. It also describes conservation February 16, 2022 | Page 19 File No. 0693-078-01 measures proposed to avoid, minimize or otherwise offset potential adverse effects to designated EFH resulting from the proposed action. 8.1. Designated EFH within the Action Area There is no habitat for coastal pelagic or groundfish species within the Action Area. The Pacific salmon fishery management unit includes Chinook Salmon, Coho Salmon (O. kisutch) and Pink Salmon (O. gorbuscha). Pacific salmon designated EFH includes all streams, lakes, ponds, wetlands and other water bodies currently or historically accessible to salmon in Washington State, except above impassable barriers. Estuarine and marine areas extend from the nearshore and tidal submerged environments within Washington territorial waters out to the full extent of the exclusive economic zone offshore (PFMC 2014). Therefore, the Cedar River is designated EFH for Pacific salmon. 8.2. Effects of the Proposed Action on EFH As stated in the BA analysis above, the project will not alter habitat within the Cedar River. Project impacts to fish habitat are limited to alteration of riparian vegetation. Impacted vegetation predominantly consists of invasive species. These areas will be restored following completion of construction, in accordance with the approved mitigation plan for the project, which has considered levee and airport restrictions,. Native communities, once they are established, are expected to provide greater levels of riparian function than many of the existing communities affected by the project. Proposed project-specific mitigation is anticipated to offset impacts and therefore the appropriate effect determination for Pacific salmon EFH is will not adversely affect. 9.0 CONCLUSIONS The Cedar River Section 205 Levee Certification Project will involve levee improvements to the existing Cedar River levee system to meet current flood design standards necessary for levee certification. The project will require the use of heavy machinery including excavators and concrete saw and paving equipment. Project impacts will include operation of construction equipment, construction noise, riparian habitat alteration and potential impacts to water quality. However, the project has been carefully designed to minimize these effects and mitigation has been identified to offset unavoidable impacts as described in this report. The Action Area for the project was defined as the sum of extents of all project effects on the environment and comprises a 446-foot-radius around the project site. The Action Area was largely dictated by the extent that in-air construction noise could permeate the environment. There is no work proposed below the OHWM. It was determined that fish species are the only ESA-listed species that may be present in the Action Area for the project, including Chinook Salmon, Steelhead and Bull Trout. The effects determination for the project is not likely to adversely affect Puget Sound ESU Chinook Salmon, Puget Sound DPS Steelhead trout and Bull Trout. The effects determination for designated critical habitat for both Chinook and Steelhead is also not likely to adversely affect. The project will have no effect on other listed species, including no effect on designated critical habitat for Bull Trout. Additionally, the project will not adversely affect EFH for Pacific salmon.

This report includes information that the Washington Department of Fish and Wildlife (WDFW) maintains in a central computer database. It is not an attempt to provide you with an official agency response as to the impacts of your project on fish and wildlife. This information only documents the location of fish and wildlife resources to the best of our knowledge. It is not a complete inventory and it is important to note that fish and wildlife resources may occur in areas not currently known to WDFW biologists, or in areas for which comprehensive surveys have not been conducted. Site specific surveys are frequently necesssary to rule out the presence of priority resources. Locations of fish and wildlife resources are subject to variation caused by disturbance, changes in season and weather, and other factors. WDFW does not recommend using reports more than six months old. 6/28/2021 Protected Resources App https://www.webapps.nwfsc.noaa.gov/portal/apps/webappviewer/index.html?id=7514c715b8594944a6e468dd25aaacc9&extent=-13608376.5375%2C6020796.9238%2C-13599204.0941%2C6024962.…1/1 0.3km 0.2mi -122.204713 47.499809 Degrees + –   Protected Resources App v1.0 Esri World Geocoder (1 of 2) ESA Critical Habitat Designation: Steelhead (Puget Sound DPS) FID 2348 Shape STRM_NAME Cedar River USEDESC Known Juvenile Rearing LENGTH 1.80 Zoom to 6/28/2021 Protected Resources App https://www.webapps.nwfsc.noaa.gov/portal/apps/webappviewer/index.html?id=7514c715b8594944a6e468dd25aaacc9&extent=-13608376.5375%2C6020796.9238%2C-13599204.0941%2C6024962.…1/1 0.3km 0.2mi -122.205400 47.498244 Degrees + –   Protected Resources App v1.0 Esri World Geocoder (2 of 2) ESA Critical Habitat Designation: Salmon, Chinook (Puget Sound ESU) FID 1159 Shape LENGTH 9,917.19 LLID 1222590476452 STRM_NAME Cedar River Zoom to April 15, 2021 United States Department of the Interior FISH AND WILDLIFE SERVICE Washington Fish And Wildlife Office 510 Desmond Drive Se, Suite 102 Lacey, WA 98503-1263 Phone: (360) 753-9440 Fax: (360) 753-9405 http://www.fws.gov/wafwo/ In Reply Refer To: Consultation Code: 01EWFW00-2021-SLI-0924 Event Code: 01EWFW00-2021-E-01806 Project Name: Cedar River 205 Levee Recert Project Subject:List of threatened and endangered species that may occur in your proposed project location or may be affected by your proposed project To Whom It May Concern: The enclosed species list identifies threatened, endangered, and proposed species, designated and proposed critical habitat, and candidate species that may occur within the boundary of your proposed project and/or may be affected by your proposed project. The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.). New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. The species list is currently compiled at the county level. Additional information is available from the Washington Department of Fish and Wildlife, Priority Habitats and Species website: http://wdfw.wa.gov/ mapping/phs/ or at our office website: http://www.fws.gov/wafwo/species_new.html. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list. The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat. 04/15/2021 Event Code: 01EWFW00-2021-E-01806   2    ▪ A Biological Assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological evaluation similar to a Biological Assessment be prepared to determine whether or not the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a Biological Assessment are described at 50 CFR 402.12. If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species, and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found in the "Endangered Species Consultation Handbook" at: http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF Please be aware that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16 U.S.C. 668 et seq.). You may visit our website at http://www.fws.gov/pacific/ eagle/for information on disturbance or take of the species and information on how to get a permit and what current guidelines and regulations are. Some projects affecting these species may require development of an eagle conservation plan: (http://www.fws.gov/windenergy/ eagle_guidance.html). Additionally, wind energy projects should follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to migratory birds and bats. Also be aware that all marine mammals are protected under the Marine Mammal Protection Act (MMPA). The MMPA prohibits, with certain exceptions, the "take" of marine mammals in U.S. waters and by U.S. citizens on the high seas. The importation of marine mammals and marine mammal products into the U.S. is also prohibited. More information can be found on the MMPA website: http://www.nmfs.noaa.gov/pr/laws/mmpa/. We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Tracking Number in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

Endangered Species Act Species There is a total of 5 threatened, endangered, or candidate species on this species list. Species on this list should be considered in an effects analysis for your project and could include species that exist in another geographic area. For example, certain fish may appear on the species list because a project could affect downstream species. IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA Fisheries , as USFWS does not have the authority to speak on behalf of NOAA and the Department of Commerce. See the "Critical habitats" section below for those critical habitats that lie wholly or partially within your project area under this office's jurisdiction. Please contact the designated FWS office if you have questions. NOAA Fisheries, also known as the National Marine Fisheries Service (NMFS), is an office of the National Oceanic and Atmospheric Administration within the Department of Commerce.
