PROPOSAL DESCRIPTION: The applicant is requesting a Shoreline Exemption to
rehabilitate areas of the 205 Levee Project damaged from the 2009 January flood in the
Cedar River. The 2009 flooding event sheared off embankment soils, damaged gabion and
earth toes from the 205 levees at river mile 0.20 for approximately 160 linear feet.
Additionally, a 100 linear foot section upstream experienced embankment scour. In its
current condition, the levee offers only 10 -year flood level protection.
The construction of the 205 Levee was originally approved in 1998 and constructed between
1999 and 2000. The original Shoreline Substantial Development Permit, City file number
LUA97-192 was issued in February of 1998 and was accompanied by the adoption of the
Existing Environmental Impact Statement completed by the US Army Corps of Engineers.
The original 205 Levee Project included a series of interconnected levee and floodwalls to
contain river flows greater than the 100 -year flood event. This levee and floodwalls system
protects the Renton Airport and Boeing properties as well as other commercial properties

and structures adjacent to the Cedar River.
The proposed repairs at river mile 0.20 include removal of 160 linear feet of gabion wall,
establishment of a rock toe in the footprint of the gabion toe, pull back the bank to a 2:1
slope, install a 12 -inch gravel and/or spall filter blanket underline with 24 inches of riprap
armor. At river mile 0.22 the repairs include the placement of small rock along the exposed
shoreline to prevent further erosion and scour, placement of riprap material for bank
protection at the Ordinary High Water level, and plant willows in the sandbar adjacent to the
bank and larger shrubs along the shoreline. These repairs would restore the levee to the
100 -year channel capacity.
This restoration project has been reviewed for concurrence with the U.S. Department of Fish
and Wildlife pursuant to section 7(a)(2) of the Endangered Species Act and it was determined
the proposed actions are "not likely to adversely affect” Bull trout. Furthermore, the project
has been reviewed by the National Oceanic and Atmospheric Administration (NOAA) and
National Marine Fisheries Services (NMFS). The review by NMFS resulted in several
measures to avoid adverse affection on ESA -listed fish, which included the following: (1) Limit
in -water work to August 1- August 31 when aquatic species are at least risk; (2) Replace
disturbed vegetation with appropriate plantings; (3) New riparian plantings shall be
monitored, and replanted as necessary for a minimum of 3 years following project
completion; (4) Minimize soil disturbance and use appropriate sediment control measures;
(5) Apply standard BMPs to prevent contaminated spills, and; (6) Monitor the construction
reach for turbidity and temporarily halt work if high turbidity results from construction
activities.
An exemption from a Shoreline Management Substantial Development Permit is hereby granted
on the proposed project in accordance with RMC 4-9-190.C.5, and/or for the following reason(s):
Normal maintenance or repair of existing structures or developments, including
damage by accident, fire or elements.
1. "Normal repair" means to restore a development to a state comparable to its
original condition, including but not limited to its size, shape, configuration,
location and external appearance, within a reasonable period after decay or partial
destruction, except where repair causes substantial adverse effects to the
shoreline resource or environment.
2. Replacement of a structure or development may be authorized as repair where
such replacement is the common method of repair for the type of structure or
development and the replacement structure or development is comparable to the
original structure or development including, but not limited to, its size, shape,
configuration, location and external appearance and the replacement does not
cause substantial adverse effects to shoreline resources or environment.

human Created pond exists an the NARCO do off the extreme south edge of the proposed
spoils pile location. The USACE feels this Is a water of the United States; City Code Indicates
this Is possibly a Category " wetland (4.32.3 D,3.) and may require a 25 foot setback (4.32-3 F
(3)). We will provide a minimum 25 foot setback from the pond.
Sediment transport analysis of the selected project design Indicates that maintenance dredging
may be required as often as every throe years to maintain the design level of protection.
Approximately 50% of the Cmaments] plantings in the Park downstream of Logan Avenue will be
removed and several trees along the left bank will also be removed. The Park will be restored
after completion of the work.
Storm drainage Improvements, Including water quality treatment, will be provided on the NARCO
elle if It is used. This would cenelst of ■ grass lined swale marginal to the dredge spoils pile,
setting pond with elevated outlet, and normal construction erosion control meawres, it should
be noted that the dredge spoils will consist primarily of very clean gravel and rock, which are
sooty woll dralning, and will not readily erode In a stockpile. Therefore the dredge spelt stockpile
will not be covered, and additional slormwater detention will not be necessary.
A spawning channel Is to be Installed upstream at the Coder River Regional Park oust upstream
Of the Maplewood Golf Course). The spawning channel will require excavation of approximately
7500 Cy of native material and placement of up to 700 CY of gravel and bank stabilization
materlale. Excavated materials will be re.distfibuted on site or transported elsewhere in the
project as needed. Excavation of the spawning channel will require the removal of several trees
(primarily cottonwoods and broad leaf maples) and some other vegetation. Alter constr u tlon,
the areas will be replanted with trees and shrubs.
Impervious area will not be changed by the project. Locally, where levees block existing flows,
the area will be regraded to prevent ponding. Existing outfalls to the river will be fitted with flap
gates to eAminate flow reversal during high flow periods.
2. ENVIRONMENTAL REVIEW
Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21C. 1071 as
amended), on January 6, 1990 the Environmental Review Commitee adopted the EIS Issued by
the US Army Corps of Engineers.

5. MITIGATION AND MONITORING PLAN
The Corps has selected the minlmaf dredging alternative (4 feet) as the preferred
alternative and the proposed mitigation and monitoring plan reflect thA Impacts
identified for this alternative. However, the local sponsor previously expressed an
interest In pursuing the moderate dredge alternative, possibly after Initial construction If
the sedimentation rate in the channel requires more frequent dredging than is
anticipated. Therefore, after discussing mitigation for the.preferred alternative, Section
5,7 was Included in the draft EIS and discusses likely additional mitigation.that would be
required for the moderate dredge (6 foot) alternative. This section has been retained in
the final EIS to show the differences between the alternatives.
For the preferred alternative, Impacts have been avoided to the maximum extent
practicable while still accomplishing the project purpose of 100 year flood control along
the lower Cedar River In Renton. The delta will not be dredged as a part of initial
construction because it does not affect flood control levels and may provide significant
environmental values to fish and wildlife species. The vegetation along the right bank
between Logan Avenue and the south Boeing bridge will be left intact because of the
riparian benefits it provides. Headcutting will be avoided or significantly reduced by the
additional dredging upstream of Logan Avenue to bring the dredged slope up to the
existing grade. This will prevent rapid sediment movement upstream of Logan Avenue
following construction and maintenance dredging and avoid impacts to spawning
salmon and their eggs.
u i u •i311114DIOW1
The preferred alternative minimizes dredging induced impacts to the maximum extent
feasible. It provides a balance between dredge depth and levee height to maximize
flood control while reducing the extent of lake backwater by minimizing dredge depth to
to 4 feet (1.2 m). Possible adverse impacts from the placement of riprap along the left
bank for 400 feet (120 m) between Logan Avenue and the south Boeing bridge have
been minimized by placing riprap only below the OHWM and during construction the
rock will be staggered, rather than creating a smooth rock face, to create holding areas
for adult salmon. The construction and maintenance work window (for In -water work)
f has been voluntarily reduced to June 15 - August 31, rather than the usual June 15 -
.,j September 15 window because of the early sockeye and chinook adult migrants that
enter the river In early September.
5.3 Rectification of Adverse lmoact5
Adverse impacts that can be rectified during and after construction Include impacts to
riparian vegetation from the construction of levees. Existing vegetation along the left
bank will be removed during construction of the sheet -pile fioodwall and rock toe to
protect this bank. This impact will be rectified by replanting vegetation along the bank,

been observed In this area during the salmon spawning season. so eflectNe loss of

2) Periodic loss, of approximately 45.000 feet' (4100 m) of bank scour
holding areas for adult salmon, juvenile salmonArout and resident trout. This habitat
will be lost Immediately after periodic maintenance dredging due to the trapezoidal
shape of the dredged channel. It Is expected that during the first winter season after
dredging, the channel will readjust Itself and create bank scour pool habitat. The
253,000 ft' (5.8 acres or 23,230 m) of Increased lake backwater will provide additional
lower velocity holding habitat below 3300 feet (1000 m) from the mouth, but will not

approximately 2000 feet (60D m) from the mouth, In approximately a 6-1D feet (nm
wide strip. These plantings will temporally replace vegetation lost on the left ba -10
nk
during construction and also contribute In and detrital material to the river to
compensate for possibly reduced aquatic Invertebrate production. Additionally this
` riparian vegetation because of its roots and downed limbsArees will likely create scour
pools for additional adult salmon holding habitat.
On the right bank the trees will be planted on 20 foot centers, and the shrubs will be
plant
grouped with the trees; approximaL'!V 6 shrubs per tree. Ground eillbe d
on 3 foot centers. This planting scheme will provide a total of approximately00 tes,
1200 shrubs, and 3500 groundcovers of various types. The openings for public access
and viewing will be approximately 30 feet wide, with a minimum of 4 access locations
.;: provided.
2) Create a groundwater fed pool and side channel at an upstream
floodplain location with groundwater near the surface (upper Elliot levee site, see
Figures 178.19). This pool and side channel will be connected at the downstream and
A to the Cedar River to allow use of the channel by both adult salmon for spawning
F; habitat and juvenile salmon for winter refuge and rearing. The channel will be
approxlmately 9000 to (826 Wf in size with additional pond habitat. It is expected that
this channel will replace the poor to moderate quality spawning habitat lost due to the
project and will additionally increase survival for the eggs in the gravel, over existing
conditions, end will compensate for probable Increased predation In the lower river.
Survival of the eggs will be increased because the channel will have moderate velocity
flows except during flows X6300 cis and will not be scoured as easily as mainstem
areas. Native trees and shrubs will be planted (or lett in place) in two acres
*r, surrounding the side channel and pond.
'The groundwater ted channel will be oversized to allow for less than complete spawning coverage. It is
r -i expected that only 50% of the channel will actually be used for spawningthis will adequate
lY
' compensate for lost spawning habitat, as well as providing additional area for increased production of try.

determined during the permitting process, with the appropriate state and federal
�i resource agencies and the Muckleshoot Indian Tribe. it Is expected that additional
plantings to replace dead plants, or an alternate mitigation site for salmon spawning
would need to be accomplished as a contingency measure.
The evaluation of Impacts In the planning process and this EIS Indicates, based on
three years of data, that longfin smell spawning will not be significantly affected by the
construction of a flood control project. In order to confirm and document that this Is the
case, longfin smelt spawning will be monitored.
A
Eggs will be collected for longlin smelt in years 1,2 and 4 following construction (one
low year and two high spawning population years, 1899, 2000, and 2002). Eggs will be
sampled at 300 meter Intervals similar to the study conducted in 1998. Three samples
will be collected at each transect up to 1800 meters from the mouth on a monthly basis
from late January to May. Egg abundance and distribution will be compared to the pro -
dredging studies.
OIn order to ensure that the mitigation measures are adequate, sockeye redd counts will
be conducted yearly for five years from Wells Street to the mouth. These counts will
occur once monthly in October, November and December (if possible). Spawning
distribution will be compared to counts prior to construction. The side channel will also
be observed for spawning as described above,
5.7 Imogets and Mitigation for hdgdwWa Dredge Aftemative
The moderate dredge alternative would not avoid and minimize adverse Impacts to the
extent that the preferred alternative (minimum dredge alternative) does. The same and
additional unavoidable adverse Impacts would likely occur compared to the preferred
alternative, primarily due to the increased area of lack backwater that would result from
a deeper dredge depth. Expected additional unavoidable adverse Impacts are:
1) Lass of poor to good quality adult salmon (sockeye, chinook, coho and/or
steelhead) spawning habitat between 1000 feet (300 m) and 4200 feet (1300 m)

upstream of the mouth, which will become embedded with sands and finer sediments 1
due to the lake backwater area Increase. A maximum of 435 redds have been -...:Y
observed In this area during the salmon spawning season, so effective loss of habitat Is
estimated to be 4740-7100 fe (435.850 m').
2) toss of 352,000 ft' (8 acres or 32,320 m') of probable coastrange and
torrent sculpin habitat due to lake backwater increase; this habitat will now be suitable
for prickly sculpin and will Increase prickly sculpin habitat by an equal amount. An
Increase in prickly sculpin habitat and population will likely cause a decrease in sockeye
fry survival In the lower river.
Other unavoidable adverse Impacts would be similar to that described for the preferred
allernative'ln Section 5.4.
In order to adequately mitigate for these additional impacts, it is expected that y
Increasing the size of the proposed groundwater fed pond and channel (Section 5.5)
would suffice. Increasing the size of the pond/channel to 18,000-20,000 fl' (11352.1840
rn j and Increasing plantings to three acres surrounding the pond/channel should O
adequately mitigate for the Increase In lake backwater area due to additional dredging
depth. Additional rearing habitat for chinook would also need to be created to
compensate for reduced survival due to predation In the lower river. h:

6. STATUS OF COMPLIANCE WITH APPLICABLE LAWS AND REGULATIONS
Throughout the planning process, coordination with representatives from federal, state
and local agencies, and the Muckleshoot Indlan Tribe has been conducted. Table 5,
below, summarizes the status of compliance with various applicable laws and
regulations.
r
This will be In compliance with the National Environmental Policy Act
�;u4
proposed project
(NEPA) and the State Environmental Policy act (SEPA) as a result of this EIS process
and the serious consideration of comments received. The public review of the draft EIS
revealed that there was no significant controversy about the proposed protect and
;,.
preferred alternative. In general, most agencies and individuals support the project
(see Appendix A). There were concerns about impacts to chinook salmon, especially in
"` `
•.!; light of their potential listing as an endangered species. There were also requests for
more information about the proposed mitigation site. In several sections, information
'
has been added to clarify confusion which some commentors had about statements
made in the draft EIS. Interested parties and agencies will continue to be Involved in
the final designs of the project and mitigallon,
This proposed project will be in compliance with the Fish and Wildlife Coordination Act
(FWCA) and Endangered Species Act (ESA) per consultation with the U.S. Fish 8
Wildlife Service (FWS). The Corps has submittad a biological assessment (BA) of
potential effects of the project on threatened or endangered species and the FWS has
concurred with that assessment. The FWS has prepared a draft and final FWCA
Report and the final report is enclosed as Appendix B to this final EIS. Responses of
the Corps to the comments and recommendations within the final FWCA Report are
included in Appendix B.
The Corps has consulted with the Stale Historic Preservation Office (SHPO) on the
possible effects on cultural or historic resources. The SHPO has concurred that no
a,
effects are expected (enclosed with DPR).
The Corps is conducting an evaluation and review of compliance with Section 404 of
the Clean Water Act, the Coastal Zone Management Act, and Executive Orders 11988
and 11990.

Dear Mr. Fitzpatrick:
This letter is to confirm that the above -referenced project will not require an individual water -
quality certification from the Department of Ecology (Ecology). Upon review of the May 4th,
2011 Memo that the Corps submitted, Ecology has determined that the project meets the
requirements for Washington State 401 Water Quality Certification under Nationwide Permit
(NWP) 3, Maintenance. Therefore; an Individual 401 certification will not be required for this
project.
If at any time the project changes from what is described within the May 4t' memo the Corps shall
notify Ecology in writing before the new work begins. At that time Ecology will determine if any
additional review is required.
Please contact me if you have any questions regarding this letter at (360) 407-6068 or e-mail

RE: PROJECT NARRATIVE Shoreline Exemption Request for "Cedar River 205
Levee Rehabiliation Project"
To City of Renton Development Services:
The City of Renton Surface Water Utility is requesting Shoreline Exemption through the
City of Renton Shoreline Master Program and State Shoreline Management Act. This
project proposes to rehabilitate areas of the 205 Project damaged from the 2009 January
flood which sheared off embankment soils, damaged gabions and earth toes is on the
Cedar River Section 205 levee system at River Mile 0.20 {just upstream of the river boat
launch).
n The proposed project briefly described above repairs the original 205 Project that was
approved in 1998 and built in 199912000. The original shoreline permit included
V" construction of levees, dredging, tree planting, and construction of floodwalls. Damages
caused by the recent 2009 January floods on the levee is necessitating repair of the
original project that erected the right levee (Parks side). The Surface Water Utility is
requesting an exemption for emergency construction based upon the following eligible
list:
1. The project is repairing an existing structure that was damaged by the
January 2009 flood that was previously permitted through the Cedar River
Section 205 Project.
2. The project is related to emergency construction necessary to protect
property from damage by the elements prior to start of 2011 winter river
flows.
The following project narrative, maps, figures, and proposed construction activity
explains the extent of the repair project.
Proiect Narrative:
The proposed repair project, "Cedar River Section 205 Levee Rehabilitation Project",
is located within the City of Renton, in King County, Washington. The City of Renton
and Army Corp of Engineers (ACOE) jointly constructed the Section 205 Flood Control
project in 1999 with mitigation elements completed in 2001. The 205 Project is located
between the mouth of the Cedar River to the Williams Street Bridge or approximately 1.5
miles upstream of the mouth. The original project components included a series of
interconnected levee and floodwalls to contain river flows greater than the 100 -year flood
event. This levee and floodwall system protects the Renton airport to the west and
Boeing properties to the east as well as other commercial properties and structures
adjacent to the Cedar River. The location of the repairs within the original 205 Project
limit is at Cedar River Mile (RM) 0.20 on the right bank (Parks side), and at RM 0.22 on
the right bank (at the sand bar location and immediately upstream of the gabion section).
R�0.2�0, will be referred to as " q eA" and Q22will be referred to as " _ite B". See
Figure 1 for site plan project locations.
CONSTRUCTION START AND END DATES:
The proposed rehabilitation work needs to begin in -water work for Site A and Site B
during August l" to August 31 st, as allowed by the Cedar River in water work window
by NMFS and USFWS. The remaining out of water work would be completed after
before August l" and some after August 31". These dates are within the "fisheries"
construction period where any disturbance will not greatly affect migrating fish in the
Cedar River. If work cannot be started before August 15`x, then this project will be
scheduled to begin during the summer 2012. The project is anticipated to be finished in
approximately 20 working days with 12 to 14 days of in -water working days.
OTHER PERMITS:
Other permits required for the proposed project include NOAA Fisheries approval with
mitigation proposed `on-site' to compensate for placement of interwoven rock and
spawning gravels to fill in voids in the rock. Vegetation is proposed to replace trees and
brush disturbed during construction and includes additional willow plantings in the sand
bar area. The Washington Department of Fish and Wildlife (WDFW) has been contacted 1
to inquire about any state HPA requirements. The original NEPA/SEPA is still enforce
for this project and was developed by the Army Corp of Engineers (ACOE) via the Final
Environmental Impact Statement that was adopted by the City of Renton as our SEPA.
Public hearings were held in the City for the FEIS that the City worked closely with the
USACE with in writing, reviewing and adopting the FEIS.
EXISTING AND PROPOSED LANDUSE:
The current use of the site is primarily as a levee and park area for the setback portions.
No proposed landuse changes are proposed with this project. This project is primarily to
remedy -damaged property from the January 2009 storm event that caused high river
flows on the Cedar River.
SPECIAL SITE FEATURES:
The project site includes levees with vegetation near the river shore. No steep slopes or
wetlands exist on-site excluding the Cedar River in stream area. Vegetation that will be
disturbed was part of the original project and will be replaced with 15 gallon trees and
brush. Grass areas disturbed will also be replaced.
SOIL TYPES AND FEATURES:
Soils in the project area consist of Oridia-Seattle-Woodinville association types with
somewhat poorly drained with nearly level soils in major stream valleys. Gravels exist
on the stream bank bottom with fill and side slopes occupying more organic and sandy
material. Drainage onsite in the park all drain directly into the Cedar River.
ESTIMATED CONSTRUCTION COSTS:
The estimated construction cost to construct the project is approximately $297,000.00,
which includes costs for engineering and design by ALOE. The estimated fair market
value of the project is negligible with all post -construction values of the property
remaining the same. One can even argue that if left to deteriorate with future high river
flows of the lower Cedar River, than the future value of the surrounding properties would
be greatly diminished if flooding were to occur and left to deteriorate. The benefit to the
immediate commercial properties is approximately $14,000,000.00 as assessed by the
ACOE in their benefit to cost analysis.
ESTIMATED UANTITIES:
Class III riprap of approximately 4,000 tons (or 300 cubic yards) are estimated to be
placed to stabilize the levee. The floodway storage will be increased as a result of the
project due to pulling back the slope from it's existing toe.
NUMBER, TYPE, AND SIZE OF TREES TO BE REMOVED:
Approximately 27 project planted trees are expected to be removed in the project vicinity
area and replaced with 15 gallon bucket trees approved by City Parks. Mostly ash trees
and bush plantings will be removed in order to place rock at the toe of the bank. Trees
and brush will be re -placed where they were removed. In addition, additional willow
trees will be planted in the sand bar area.
DISTANCE FROM ORDINARY HIGH WATER MARK OHWM OF THE
SHORELINE:
Work will be constructed immediately within the OHWM to stabilize the levee. No
equipment is anticipated to be placed in the Cedar River streambed, but will be staged on
the bank with rock placed one at a time to minimize turbid flow in the Cedar River.
EXISTING SHORELINE:
The existing shoreline conditions along the project site include sections of eroded soil
sloughing into the river, some ash and brush on the top of the vertical banks, some
previously planted 205 brush along the levee slope/bench, and grass on the slope.

Dear Ms. Walker:
Project: Cedar River Levee Rehabilitation of Flood Control Works
This is in response to your January 21, 2011, letter requesting our concurrence with your
determination that the proposed action in Puget Sound, King County, Washington, would "not
likely adversely affect" federally listed species. A photocopy from your transmittal document(s)
describing the proposed action is enclosed.
Specifically, you requested informal consultation pursuant to section 7(a)(2) of the Endangered
Species Act of 1973, as amended (16 U.S.C. 1531 et seq.) for the federally listed species
identified below (only those species that have been checked are addressed in this consultation
request (See Enclosure).
® Bull trout (Salvelinus confluentus)
If you requested consultation for the bald eagle, please note that the bald eagle was removed
from the Federal List of Threatened and Endangered Wildlife, effective August 8, 2007. Given
that your project will be implemented after that date, consultation under section 7(a)2 of the
Endangered Species Act is not required. We have therefore not provided concurrence on your
effect determination for the bald eagle.
Based on the information provided in and/or with your cover letter and any additional
information, we have concluded that effects of the proposed action to the above -identified
federally listed resources would be insignificant and/or discountable. Therefore, for the reasons
identified in the enclosures to this letter, we concur with your determination that the proposed
TAKE PRIDE'* .�
Michelle Walker 2
action is "not likely to adversely affect" the above -identified federally listed resources. This
letter and its enclosures constitute a complete response of the U.S. Fish and Wildlife Service to
your request for informal consultation.
This concludes consultation pursuani to the regulations implementing the Endangered Species
Act (50 CFR 402.13). This project should be re -analyzed if new information reveals effects of
the action that may affect listed species or critical habitat in a manner, or to an extent, not
considered in this consultation. The project should also be re -analyzed if the action is
subsequently modified in a manner that causes an effect to a listed species or critical habitat that
was not considered in this consultation, and/or anew species is listed or critical habitat is
designated that may be affected by this project.
Our review and concurrence with your effect determination is based on the implementation of
the project as described. It is the responsibility of the Federal action agency to ensure that
projects that they authorize or carry out are in compliance with the regulatory permit and/or the
ESA, respectively. If a permittee or the Federal action agency deviates from the measures
outlined in a permit or project description, the Federal action agency has the obligation to
reinitiate consultation and comply with section 7(d).
If you have any questions about this letter or our joint responsibilities under the Endangered
Species' Act, please contact the consultation biologist identified below, of this office.

BULL TROUT
ENDANGERED SPECIES ACT
SECTION 7 INFORMAL CONSULTATION CONCURRENCE RATIONALE
Project Name: Cedar River Levee Rehabilitation of Flood Control Works
DIRECT EFFECTS
1, Buil trout are not expected to be in the action area either because of the location of the action
or because the action would occur during the recommended work window when bull trout are
not anticipated to occur in the project area: Therefore, direct effects to bull trout from the
proposed project would be discountable because of the following:
® The action area of the proosed Project is located in the lower Cedar River, where at the
resent time bull trout occurrence is rare. Also all construction activities will occur in
the dry.
INDIRECT EFFECTS
1. Bull trout are not expected "to be in the action area; therefore, indirect effects from operation
of the proposed action and use of the facility after construction (if applicable) would be
discountable because of the following: .
® The action area of the DrQposed prJect is located in the lower Cedar River where at the
present time, bull trout occurrence is rare.
2. Bull trout may or may not occur in the action area; however, effects to bull trout via their
prey resources would be insignificant because of the following:
® All construction activities will occur during low flows and outside the wetted channel in
the -dry
of the Cedar River.
3. Bull trout occur in the action area; however, with regard to other indirect effects
® Recreational use ofwatercraft'that would result from the proposed project would not
exceed normal background sound levels in the project area. Therefore, effects are
expected to be insignificant.
Many areas of Puget Sound contain high-value spawning habitat for bull trout prey resources such as surf smelt
(Hypomesus pretiosus), sand lance (Arnmodytes hexapterus), and Pacific herring (Clupea harengus). This
determination may not be appropriate for projects that would have significant, long-term negative effects to bull
trout prey resources.

2. DESCRIPTION OF THE PROJECT AREA AND PROPOSED ACTION
In the project area, the Cedar River is a confined, single -thread, low gradient artificial channel (the
historic channel flowed into the Black River). Renton Airport occupies the left bank, while the right
bank contains a city park and a Boeing. manufacturing plant. The thalweg of the river is primarily
located adjacent to the left bank.
Within the project reach, the river is highly modified and provides generally poor habitat for fish and
other aquatic species. The channelized lower Cedar River lacks complex habitat features such as
pools and off -channel areas because of armored banks and residential land uses (Puget Sound
Recovery Plan 2005). The river at this point primarily functions as a backwater for Lake Washington
during the summer high pool, but is a riffle or run during winter low water levels in Lake
Washington. River substrate consists of gravel and cobble, but is embedded with sediment. The
gravel is sometimes used for spawning by"Chinook salmon, but is more often used for spawning -by
sockeye salmon.
The levee at this site is a berm, set back a few yards from the water, covered with mowed lawn,
planted with trees and is part of a park area used by the public for recreation. The bank has been
planted with Nootka rose; it also has willows, ash, and alders. There are small embayments where
sediment accumulation has occurred. Damage to the bank has occurred, with some bank erosion and
gabion deterioration.
The repair will restore 100 -year channel capacity, but does not necessarily meet USACE or FEMA
levee certification standards. The action will include approximately 260 linear feet (LF) of repair
along the right bank of the levee.
Repair work will begin at RM .20 and move upstream. The project consists of removing 160 LF of
gabion wall. In place of the gabion wall the following repairs will occur: A rock toe will be
established at the location of the gabion toe. The slope will be pulled back to achieve a 2H:1 V slope.
This will enable more water to be conveyed naturally. Lastly, a 12, inch gravel and/or spall filter
blanket overlain by 24 inches of riprap armor will be installed. Large rock will be placed individually
to minimize vibration and turbidity; however, staging of rock near the work site would involve
dumping in an adjacent upland location.
Moving 150 LF upstream of the failed gabion wall, 100 LF of small rock will be placed along the
exposed shoreline to prevent further erosion and scour, as well as deter the public from entering the
area. For specific site rehabilitation locations see Figure 1. Willowg will be planted in the sand bar
adjacent to the bank, and larger shrub -like foliage will be planted along the shoreline. Riprap
material will be placed for bank protection at the Ordinary High Water (OHW) level. See -Appendix
B for complete site designs.
Between the two reaches, the 150 LF of gabion protection is intact and in good shape. Streambank
material is stable, and has been colonized by numerous tree and brush species. Removal of this
gabion protection to repair with currently accepted standards (rock revetment) would disturb
additional sections of the existing streambank and would only provide minimal additional protection.
The gabion ends in this reach as well.
Removal of trees including willow, ash, shore pine, alder and nootka rose shrub species will occur
within the project reach. in total, 26 trees and 75 shrubs will be removed. Replanting of willows as
well as native red -osier dogwood in the riparian area will occur from October -December for potted
stock and January -February for bare -root stock. Willow plantings on the adjacent sandbar will be
undertaken -the following March. The willows will promote shading for salmonids. Willows on this
sandbar will be considered temporary features and may be washed out during a flood event if root
growth does not establish prior to a large flood event.
All access will be on City of Renton roadways, including existing utility roads on City of Renton
park lands, and staging will occur on these same park lands (Figure 2). Construction is scheduled to
start August 1, 2011 and be'completed by August 31, 2011.
This alternative offers the least expensive repair and the best solution to the repair of flood control
damage, while considering the pre -flood condition. All bank protection material will consist of clean,
non -contaminated material. The equipment to be used includes: hydraulic excavator, backhoe, dump
truck, and bulldozer. Repairs to both sites will be within the footprint of the existing levee.
3, CONSERVATION MEASURES
The NMFS approved work window for instream construction in this reach is 1 August to 31 August.
Utilizing these dates, the levee repair is scheduled to occur between August 1 and August 31, 201 L
The terrestrial environment at this site is highly urbanized and provides very limited wildlife habitat.
Following construction, the riprap slope will be covered with soil above the ordinary high water line
(OHWL), hydroseeded. Red -osier Dogwood and willows will be replaced in kind. Increased
planting density at the site will occur where practical. -No offsite plantings will take place.
1n addition, several construction best management practices (BMPs) will be implemented:
• A construction representative will visually monitor the project reach for presence of adult
salmonids through the use of polarized sunglasses;
• A construction representative will monitor for turbidty changes in the water. Visual
monitoring will continue throughout the construction period. Monitoring shall recommence
with erosion control failure or observable high turbidity due to project activities;
+ Biodegradable hydraulic fluids will be used in the machinery at the site;
+ Refueling will occur in the staging area on the landward side of the levee; no equipment
fueling or servicing will occur within 200 feet of the water;
• At least one fuel spill kit with absorbent pads will be onsite at all times;
• Drive trains of equipment will not operate in the water,
• Soil disturbance will be minimized during vegetation removal by cutting the stems and
using a portable stump grinder to grind all stumps to ground level;
• Understory vegetation will be hand cleared and all invasive species will be disposed of
Offsite;
• Care will be taken to ensure that vegetation inputs to the Cedar River will be nominal
(e.g. falling leaves during stem cutting);
0
• Native hydroseed application following vegetation removal will be applied to land only;
• Care will be taken to ensure no hydroseed enters the river;
• Willow stakes will be planted using hand installation methods to minimize soil
disturbance; and
• All work will be performed in the dry.
4. Environmental Coordination
Because of the emergency status of this PL 84-99 project, the planning and design process for the
rehabilitation of Cedar River at Renton FCW are on a compressed schedule. Attempts have been
made by the Corps to perform as much environmental coordination as practicable prior to
construction to allow other resource agencies to comment on the.design possibilities and aid in
determination of the erects of the project on fish and wildlife species.
This action has been and will continue to be formally coordinated throughout the planning, design,
and construction phases with the following agencies as needed:
• U.S. Fish and Wildlife Service
• NOAA Fisheries
• Washington Department of Fish and Wildlife
• Washington Department of Ecology
• Muckleshoot Indian Tribe
5. ENVIRONMENTAL BASELINE AND EFFECTS OF THE PROPOSED
ACTION
5.1 Vegetation
The common riparian community along most of the downstream reaches of the Cedar River includes
a cottonwood -alder forest, with an understory of snowberry, salmonberry (Rubes spectabilis), and
sword fern (Polystichum munitum). ,In places, vine maple (Acer circinatum), Himalayan blackberry,
Indian plum (Oemleria cerasiformis), Japanese knotweed, bleeding heart (Dicentra spectabilis), giant
horsetail (Equisetum telmateia), and Pacific waterleaf (Hydrophyllum tenuipes) occur.
In contrast to the general riparian condition along the Cedar River, the terrestrial environment at
Cedar River FCW rehabilitation sites is highly urbanized and provides very limited wildlife habitat.
Riparian vegetation here is limited to a few willows (Salix sp.), ash and shore pine, alder, and nootka
rose.
Following construction, the riprap slope will be covered with soil above the ordinary high water line,
hydroseeded, then planted with red -osier dogwood, and willows where practical. The tree removal
will alter the right bank, resulting in an alteration in stream shading and a reduction in leaf fall, cover,
and wood recruitment from the removed trees. Additionally, the planted native deciduous shrubs and
trees, when mature, will help to mitigate loss of organic material formerly contributed to the river by
the removed trees. Willows will be planted on an adjacent sandbar at the site as well as along the
levee repair.

RE: . Endangered Species Act Section 7 and Magnuson -Stevens Fishery Conservation and
Management Act Essential Fish Habitat Consultation for the Rehabilitation of Flood
Control Works, Cedar River Levee, Cedar River at Renton, King County, WA. HUC
171100120106 (Lower Cedar River)
Dear Mr. Lewis:
This correspondence is in response to your request for consultation under the Endangered
Species Act (ESA) of 1973, as amended, 16 U.S.C. 1531. Additionally, this letter serves to meet
the requirements for consultation under the Magnuson -Stevens Fishery Conservation and
Management Act (MSA, 16 U.S.C. 1855).
Endangered Species Act
The National Marine Fisheries Service (NMFS) has reviewed the Biological Evaluation (BE) for
the Rehabilitation of Flood Control Works, Cedar River Levee, on the Cedar River at Renton,
King County, WA and received on May 13, 2011. The Corps of Engineers (COE) requests
concurrence with its determination that the proposed action "may affect, but is not likely to
adversely affect" ESA threatened Puget Sound (PS) Chinook salmon (Oncorhynchus
tshawytscha), ESA threatened PS steelhead (O. mykiss) and designated PS Chinook salmon
critical habitat. This consultation with the COE is conducted under section 7(a)(2) of the ESA,
and its implementing regulations, 50 CFR Part 402.
The COE is proposing to complete emergency repairs to the Flood Control Works (FCW) on the
Cedar River Section 205 Flood Control Project at river mile (RM) 0.2 on the right bank of the
Cedar River in Section 7, Township 23 N., Range 5 E. The action area is riverine and riparian
habitats in the floodplain of the Cedar River within the described 260 feet along the right bank of
the river and downstream 300 feet to account for turbidity effects.

The Cedar River Section 205 FCW project, constructed between 1998 and 2000, included the
building of earthen levees combined with steel and concrete floodwalls along both banks of the
river and dredging in the river channel. Levees and floodwalls were raised along both banks
from the confluence of the Cedar River with Lake Washington to Williams Avenue, 1.25 miles
upstream. Dredging lowered the river channel approximately four feet from the mouth to the
Logan Avenue Bridge (RM 1), gradually decreasing the slope upstream another 0.5 mile to meet
the existing grade. The goal was to reduce potential flood damage along approximately 1.5
miles of the lower Cedar River through downtown Renton, primarily protecting the Boeing
aircraft manufacturing plant -and the Renton Municipal Airport.
Major flooding occurred on the Cedar River in January 2009 with a 30 -year flood event which
caused damage to a 160 linear foot (LF) gabion along the right bank of the 205 Levee.
Additionally, a 100 LF section upstream of the gabion wall experienced embankment scour. In
its current condition, the levee offers only 10 -year flood level protection.
The repair will restore 100 -year channel capacity, but does not necessarily meet COE or FEMA
levee certification standards. The proposed action includes approximately 260 LF of repair
along the right bank of the levee and includes the following actions: (1) Remove 160 LF of
gabion wall; (2) Establish a rock toe in the footprint of the gabion toe; (3) Pull back the bank to a
2:1 slope; and (4) Install a 12 inch gravel and/or spall filter blanket overlain with 24 inches of
riprap armor.
Upstream, the following actions are proposed along 100 LF of the right bank: (1) Place small
rock along the exposed shoreline to prevent further erosion and scour; (2) Place riprap material
for bank protection at the Ordinary High Water (OHW) level, and; (3) Plant willows in the
sandbar adjacent to the bank and larger shrubs along the shoreline.
Existing trees including willow, ash, shore pine, alder and nootka rose will be removed, totaling
26 small trees and 75 shrubs in the project reach. Trees and shrubs will be replanted at a
minimum of 1:1 replacement and greater where practical.
Additional project detail can be found in the BE and in the informal consultation request letter
from the COE. This project.has the potential to affect listed fish in the Cedar through
construction activities that will; (1) disturb stream bank and adjacent stream bed habitat; (2)
disturb riparian vegetation; (2) increase the possibility for contamination from petroleum-based
products; (3) perpetuate degraded conditions of the streambank, and; (4) increase stream
temperatures due to a net decrease in shading from canopy. The project will be completed
during the approved in -water work window of August 1 to August 31 when Cedar River flows
are low and ESA -listed salmon are at least risk.
To minimize potential effects on PS Chinook salmon and PS steelhead it is expected that all
conservation measures and best management practices (BMPs) as noted in the BE and the HPA
will be followed. In particular, NMFS highlights several conservation measures to avoid adverse
affects on ESA -listed fish: (1) Limit in -water work to August 1 — August 31 when aquatic
species are at least risk; (2) Replace disturbed vegetation with appropriate plantings; (3) New
riparian plantings will be monitored, and replanted as necessary, for a minimum of 3 years
following project -completion; (4) Minimize soil disturbance and use appropriate sediment
control measures; (5) Apply standard BMPs to prevent contaminant spills, and ; (6) Monitor the
construction reach for turbidity and temporarily halt work if high turbidity results from
construction activities.
It is notable that NMFS conducted informal consultation in December, 2009, on a similar project
by the City of Renton and funded by FEMA to repair 290 feet of failed gabion basket
embankment at approximately river mile 1.3 on the Cedar River (NMFS tracking number
2009105636). GWons are an outdated and undesirable material for instream or stream
embankment use. The NMFS suggests the COE and the City of Renton consider alternative
bioengineered bank materials in this reach to avoid future repairs which can create regular and
unnecessary disturbance to aquatic resources.
Species Determination
Puget Sound Chinook Salmon
Puget Sound Steelhead
Puget Sound Chinook salmon are distributed throughout the Cedar River, utilizing the project
area for adult migration, spawning and juvenile rearing. No adult or juvenile Chinook salmon
will be in the action area during the construction window of August 1 to August 31. Typically,
0+ juvenile Chinook will have emigrated prior to August 1, and adults are not in the river until
mid to late October. Therefore, because there is very little risk of exposure of individuals to
construction activities, effects on this species are discountable.
Puget Sound steelhead may be present year-round in the action area. Water quality impacts from
sediment and temperature will be localized and temporary and easily avoided by any juvenile
steelhead present in the area. Additionally, juvenile steelhead favor faster water and not the
slower unprotected waters adjacent to the gabion basket embankment. Appropriate use of BMPs
as listed above will ensure that project effects are insignificant for this species. NMFS concurs
the proposed action "may affect, but not likely to adversely affect" PS Chinook salmon and PS
steelhead.
Critical Habitat Determination
Puget Sound Chinook Salmon
The final rule designating critical habitat for PS Chinook salmon was published on September 2,
2005 (70 FR 52630) and became effective on January 2, 2006. The Cedar Riveris designated as
critical habitat for PS Chinook salmon. Primary constituent elements (PCEs) essential for the
conservation of this ESU that support one or more life stages include: (1) Freshwater spawning
sites with water quantity and water quality conditions and substrate supporting spawning,
incubation and larval development; (2) Freshwater rearing sites with: (i) Water quantity and
4
floodplain connectivity to form and maintain physical habitat conditions and support juvenile
growth and mobility; (ii) Water quality 'and forage supporting juvenile development; and (iii)
Natural cover such as shade, submerged and overhanging large wood, logjams and beaver dams,
aquatic vegetation, large rocks and boulders, side channels, and undercut banks, and: (3)
Freshwater migration corridors free of obstruction and excessive predation 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.
Sediment introduced to the river from construction activities will be minimized by using
standard BMPs and turbidity should be temporary and not persistent for more than
approximately 300 feet downstream of the project site. Because the conservation value of PCEs
in the action area, though degraded, will be maintained, and following all BMPs will ensure that
effects to existing PS Chinook salmon habitat are insignificant, NMFS concurs that this project
"may affect, but is not likely to adversely affect" PS Chinook salmon critical habitat.
One of the strategies in the Puget Sound Salmon Recovery Plan, Lake
Washington/Cedar/Sammamish Chapter (Shared Strategy, 2007), is to "restore the Cedar River
mainstem to add more rearing habitat for ESA -listed Chinook salmon". Currently the lower
Cedar River in the action area is a single -thread artificial channel and lacks complex habitat such
as pools and off -channel areas due in some respect to armored banks and adjacent land use.
Because potential for significant restoration of this reach of the Cedar River is limited, NMFS
encourages the COE to seek opportunities to use conservation or in -lieu fee banks within the
Cedar River watershed to compensate for local loss of riparian ecological function that affects
designated PS Chinook salmon critical habitat.
This concludes informal consultation on these actions in accordance with 50 CFR
402.14(b)(1). The COE must reinitiate ESA consultation if. (1) new information reveals effects
on the actions that may affect listed species in a way not previously considered; (2) the actions
are modified in a manner that. causes an effect to listed species that was not previously
considered; or (3) a new species is listed, or critical habitat is designated, that may be affected by
the proposed actions.
Magnuson -Stevens Fishery Conservation and Management Act
Federal agencies are required, under section 305(b)(2) of the MSA and its implementing
regulations (50 CFR 600 Subpart K), to consult with NOAA Fisheries regarding actions that are
authorized, funded, or undertaken by that agency that may adversely affect Essential Fish Habitat
(EFH). The MSA section 3 defines EFH as "those waters and substrate necessary to fish for
spawning, breeding, feeding, or growth to maturity". If an action would adversely affect EFH,
the Federal action agency is required to provide EFH conservation recommendations (MSA
section 305(b)(4)(A)). This consultation is based, in part, on information provided by the
Federal action, agency and descriptions of EFH for Pacific salmon contained in Appendix A to
Amendment 14 to the Pacific Coast Salmon Plan (August 1999) developed by the Pacific Fishery
Management Council and approved by the Secretary of Commerce (September 27, 2000).
The proposed action and action area are described in this letter and in the BE. The action area
includes habitat which has been designated as EFH for various life stages of coho salmon (O.
kisutch) and Chinook salmon.
EFH Conservation Recommendations: Despite riparian replanting, NMFS is concerned about
long-term adverse effects on salmon EFH from the continued loss of riparian ecological function
at the 205 Levee, including shade, insect -drop, and litterfall. The NMFS recommends that the
COE seek opportunities to use a conservation bank or in -lieu fee bank within the lower Cedar
River watershed to compensate for local loss of riparian ecological function that affect salmon
EFH.
Implementation of this conservation recommendation has the potential to enhance the habitat
value of the 0.12 acres of EFH within the action area.
Federal agencies are required to provide a detailed written response to EFH conservation
recommendations made by NMFS within 30 calendar days of receipt of these recommendations
(MSA (section 305(b)(4)(B)) and 50CFR 600.920(k)). The response must include a description
of the measures proposed to avoid, mitigate, or offset the adverse effects of the activity on EFH.
In the case of response that is inconsistent with EFH conservation recommendations, the
response must explain the reasons for not following the recommendations, including the
scientific justification for any disagreements over the anticipated effects of the proposed action
and the measures needed to avoid, minimize, mitigate, or offset such effects.
This concludes consultation under the MSA. If the proposed action is modified in a manner that
may adversely affect EFH, or if new information becomes available that affects the basis for
NMFS' EFH conservation recommendations, EFH consultation will be reinitiated in accordance
with implementing regulations for EFH at 50 CFR 600.920(k).
