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.

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.

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.

THEIR BUFFERS, AND AREAS OF VEGETATION PRESERVATION AND
TREE RETENTION AS PRESCRIBED ON THE PLAN(S) SHALL BE
CLEARLY DELINEATED BY FENCING AND PROTECTED IN THE FIELD
IN ACCORDANCE WITH APPENDIX D OF THE CITY OF RENTON
SURFACE WATER DESIGN MANUAL (RENTON SWDM) PRIOR TO THE
START OF CONSTRUCTION. DURING THE CONSTRUCTION PERIOD,
NO DISTURBANCE BEYOND THE CLEARING LIMITS SHALL BE
PERMITTED. THE CLEARING LIMITS SHALL BE MAINTAINED BY THE
APPLICANT/ESC SUPERVISOR FOR THE DURATION OF
CONSTRUCTION.
5.STABILIZED CONSTRUCTION ENTRANCES SHALL BE INSTALLED AT
THE BEGINNING OF CONSTRUCTION AND MAINTAINED FOR THE
DURATION OF THE PROJECT. ADDITIONAL MEASURES, SUCH AS
CONSTRUCTED WHEEL WASH SYSTEMS OR WASH PADS, MAY BE
REQUIRED TO ENSURE THAT ALL PAVED AREAS ARE KEPT CLEAN
AND TRACK-OUT TO ROAD RIGHT OF WAY DOES NOT OCCUR FOR
THE DURATION OF THE PROJECT. IF SEDIMENT IS TRACKED
OFFSITE, PUBLIC ROADS SHALL BE CLEANED THOROUGHLY AT THE
END OF EACH DAY, OR MORE FREQUENTLY DURING WET
WEATHER, AS NECESSARY TO PREVENT SEDIMENT FROM
ENTERING WATERS OF THE STATE.
6.WASHOUT FROM CONCRETE TRUCKS SHALL BE PERFORMED
OFF-SITE OR IN DESIGNATED CONCRETE WASHOUT AREAS ONLY.
DO NOT WASH OUR CONCRETE TRUCKS ONTO THE GROUND, OR
TO STORM DRAINS OR OPEN DITCHES. ON-SITE DUMPING OF
EXCESS CONCRETE SHALL ONLY OCCUR IN DESIGNATED
CONCRETE WASHOUT AREAS.
7.ALL REQUIRED ESC BMPS SHALL BE CONSTRUCTED AND IN
OPERATION PRIOR TO LAND CLEARING AND/OR CONSTRUCTION TO
PREVENT TRANSPORTATION OF SEDIMENT TO SURFACE WATER,
DRAINAGE SYSTEMS, AND ADJACENT PROPERTIES. ALL ESC BMPS
SHALL BE MAINTAINED IN A SATISFACTORY CONDITION UNTIL SUCH
TIME THAT CLEARING AND/OR CONSTRUCTION IS COMPLETE AND
POTENTIAL FOR ON-SITE EROSION HAS PASSED. ALL ESC BMPS
SHALL BE REMOVED AFTER CONSTRUCTION IS COMPLETED AND
THE SITE HAS BEEN STABILIZED TO ENSURE POTENTIAL FOR
ON-SITE EROSION DOES NOT EXIST. THE IMPLEMENTATION,
MAINTENANCE, REPLACEMENT, ENHANCEMENT, AND REMOVAL OF
ESC BMPS SHALL BE THE RESPONSIBILITY OF THE APPLICANT.
8.ANY HAZARDOUS MATERIALS OR LIQUID PRODUCTS THAT HAVE
THE POTENTIAL TO POLLUTE RUNOFF SHALL BE DISPOSED OF

AS CONSTRUCTION PROGRESSES AND UNEXPECTED OR
SEASONAL CONDITIONS DICTATE, THE APPLICANT SHALL
ANTICIPATE THAT MORE ESC BMPS WILL BE NECESSARY TO
ENSURE COMPLETE SILTATION CONTROL ON THE PROPOSED SITE.
DURING THE COURSE OF CONSTRUCTION, IT SHALL BE THE
OBLIGATION AND RESPONSIBILITY OF THE APPLICANT TO ADDRESS
ANY NEW CONDITIONS THAT MAY BE CREATED BY THE ACTIVITIES
AND TO PROVIDE ADDITIONAL ESC BMPS, OVER AND ABOVE
MINIMUM REQUIREMENTS, AS MAY BE NEEDED, TO PROTECT
ADJACENT PROPERTIES AND WATER QUALITY OF THE RECEIVING
DRAINAGE SYSTEM.
10.APPROVAL OF THIS PLAN IS FOR ESC ONLY. IT DOES NOT
CONSTITUTE AN APPROVAL OF STORM DRAINAGE DESIGN, SIZE,
NOR LOCATION OF PIPES, RESTRICTIONS, CHANNELS, OR
STORMWATER FACILITIES.
11.ANY DEWATERING SYSTEM NECESSARY FOR THE CONSTRUCTION
OF STORMWATER FACILITIES SHALL BE SUBMITTED TO THE CITY
FOR REVIEW AND APPROVAL.
12.ANY AREAS OF EXPOSED SOILS, INCLUDING ROADWAY
EMBANKMENTS, THAT WILL NOT BE DISTURBED FOR TWO DAYS
DURING THE WET SEASON (OCTOBER 1ST THROUGH APRIL 30TH)
OR SEVEN DAYS DURING THE DRY SEASON (MAY 1ST THROUGH
SEPTEMBER 30TH) SHALL BE IMMEDIATELY STABILIZED WITH THE
APPROVED ESC COVER METHODS (E.G., SEEDING, MULCHING,
PLASTIC COVERING, ETC.) IN CONFORMANCE WITH APPENDIX D OF
THE RENTON SWDM.
13.WET SEASON ESC REQUIREMENTS APPLY TO ALL CONSTRUCTION
SITES BETWEEN OCTOBER 1ST AND APRIL 30TH, UNLESS
OTHERWISE APPROVED BY THE CITY.
14.ANY AREA NEEDING ADDITIONAL ESC MEASURES, NOT REQUIRING
IMMEDIATE ATTENTION, SHALL BE ADDRESSED WITHIN SEVEN (7)
DAYS.
15.THE ESC BMPS ON INACTIVE SITES SHALL BE INSPECTED AND
MAINTAINED AT A MINIMUM OF ONCE A MONTH OR WITHIN 24
HOURS FOLLOWING A STORM EVENT. INSPECTION AND
MAINTENANCE SHALL OCCUR MORE FREQUENTLY AS REQUIRED
BY THE CITY.
16.BEFORE COMMENCEMENT OF ANY CONSTRUCTION ACTIVITY,
CATCH BASIN INSERTS PER THE CITY STANDARD PLAN 216.30
SHALL BE PROVIDED FOR ALL STORM DRAIN INLETS DOWNSLOPE
AND WITHIN 500 FEET OF A DISTURBED OR CONSTRUCTION AREA,
UNLESS THE RUNOFF THAT ENTERS THE INLET WILL BE CONVEYED
TO A SEDIMENT POND OR TRAP. ALL CATCH BASIN INSERTS SHALL
BE PERIODICALLY INSPECTED AND REPLACED AS NECESSARY TO
ENSURE FULLY FUNCTIONING CONDITION.
17.AT NO TIME SHALL SEDIMENT ACCUMULATION EXCEED 2/3 OF THE
CAPACITY OF THE CATCH BASIN SUMP. ALL CATCH BASINS AND
CONVEYANCE LINES SHALL BE CLEANED PRIOR TO PAVING. THE
CLEANING OPERATION SHALL NOT FLUSH SEDIMENT-LADEN
WATER INTO THE DOWNSTREAM SYSTEM.
18.ANY PERMANENT STORMWATER FACILITY LOCATION USED AS A
TEMPORARY SETTLING BASIN SHALL BE MODIFIED WITH THE
NECESSARY ESC BMPS AND SHALL PROVIDE ADEQUATE STORAGE
CAPACITY. IF THE TEMPORARY FACILITY IS TO ULTIMATELY

PLANTING NOTES
1.VERIFY EXISTING CONDITIONS PRIOR TO BEGINNING WORK AND REPORT IN WRITING TO
ENGINEER DEVIATIONS OR CONFLICTS BETWEEN DRAWINGS, SPECIFICATIONS, AND SITE
CONDITIONS.
2.VERIFY LOCATION OF EXISTING UTILITIES AND EXISTING VEGETATION TO REMAIN PRIOR TO
BEGINNING WORK. PROTECT VEGETATION AND UTILITIES NOT NOTED FOR REMOVAL. NOT TREES
OR SHUBS SHALL BE PLANTED WITHIN 6 HORIZONTAL FEET OF OVERHEAD OR UNDERGROUND
UTILITIES.
5.PROTECT ALL EXISTING IRRIGATION DURING PLANTING WORK.
6.PRESERVE AND PROTECT ALL EXISTING TREES AND SHRUBS NOT DESIGNATED FOR REMOVAL.
NO SOIL SCARIFICATION SHALL OCCUR WITHIN THE DRIP LINE OF VEGETATION TO BE RETAINED
UNLESS APPROVED BY THE ENGINEER.
7.REMOVE ALL INVASIVE SPECIES FROM THE MITIGATION PLANTING AREA PRIOR TO INSTALLATION
USING METHODS LISTED IN THE SPECIFICATIONS.
8.DECOMPACT SOILS IN ALL PLANTING AREAS WHERE SOIL COMPACTION HAS OCCURRED. AT
MINIMUM, DECOMPACTION MUST OCCUR WHERE HARD SURFACES HAVE BEEN REMOVED AND
STAGING AREAS HAVE BEEN CLEARED.
9.SOIL DECOMPACTION IN WET SOILS AT ANY TIME OF THE YEAR OR DURING INCLEMENT WEATHER
OR DURING PERIODS OF PROLONGED DRY OR HOT WEATHER IS NOT ALLOWED WITHOUT
APPROVAL BY THE ENGINEER PRIOR TO EXECUTION IN ORDER THAT SOIL STRUCTURE WILL BE
MAINTAINED. SOIL SHOULD BE MOIST ENOUGH THAT DIGGING DOESN'T CREATE DUST, BUT DRY
ENOUGH TO DRIVE EQUIPMENT WITHOUT CREATING RUTS.
10.SMOOTH GRADE AND SEED ALL LANDSCAPE AREAS DISTURBED BY CONSTRUCTION THAT ARE
NOT NOTED TO BE PLANTED. PRIOR TO SEEDING, REMOVE ROCKS AND DEBRIS LARGER THAN 1"
IN DIAMETER AND GRADE TO MAKE SMOOTH TRANSITIONS BACK TO ADJACENT EXISTING
GRADES.
11.PROVIDE ENGINEER A MINIMUM OF 15 DAYS ADVANCE NOTICE WHEN REQUESTING PLANT
MATERIAL DELIVERY TO THE PROJECT SITE.
12.STAKE PLANT LOCATIONS FOR ENGINEER'S APPROVAL PRIOR TO PLANTING.
13.MONITORING OF MITIGATION AREAS SHALL OCCUR ONCE 30 DAYS AFTER PLANTING (STEM
COUNT AND AS-BUILT PREPARATION), ONCE EARLY IN THE GROWING SEASON OF THE FIRST FULL
GROWING SEASON FOLLOWING PLANTING, AND ONCE AT THE END OF THE FIRST FULL GROWING
SEASON.
14.IF ANY PORTION OF THE MITIGATION IS NOT SUCCESSFUL, A CONTINGENCY PLAN SHALL BE
IMPLEMENTED. SUCH PLANS ARE DEVELOPED ON A CASE-BY-CASE BASIS TO REMEDY ASPECTS
OF MITIGATION THAT DO NOT MEET STATED SITE GOALS. THE CONTINGENCY PLAN WOULD BE
DEVELOPED IN COOPERATION WITH THE ENGINEER.
15.SEE SPECIFICATIONS FOR RESTORATION SEED MIX.

DISCLAIMER. 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.

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.
