Dear Mr. Farah,
We are in receipt of the City of Renton’s letter dated January 28, 2026,
requesting assistance in repairing the damaged portion of the Cedar River Left Bank
Authorized Federal Levee, within the City of Renton, Washington. The damaged project
section is located on the left bank of the Cedar River around the South Boeing Bridge.
The total length of the damage is approximately 1,000 linear feet. Enclosure 1 is the
final Project Information Report (PIR), which contains a vicinity map and plan view
drawing of the proposed levee repair site. Enclosure 2 is the Real Estate project map
and spreadsheet reflecting the real estate document requirements for each affected
parcel.
The Government is obligated to pay 100% of construction costs for the proposed
levee rehabilitation effort, also referred to as Job No. CED-01-26. The requirements of
local cooperation are set forth in the Project Cooperation Agreement (PCA) dated May
9, 1998 (Enclosure 3) between the United States Government and the City of Renton
and apply to the proposed construction work. Listed below are three of the basic
provisions known as the A-B-C’s:
A. Furnish without cost to the United States, all lands, easements, rights-of-
way, and rights-of-entry, including levee embankment borrow sources,
and perform all necessary alteration to utilities;
B. Hold the United States free from any claims for damages arising out of the
construction; and
C. Maintain and operate the project works after construction in accordance
with regulations prescribed by the Secretary of the Army.
Enclosure 4 is a Letter of Acknowledgement and Attorney’s Certificate of
Authority that will affirm your continued obligation of providing the A -B-C’s presented.
Please have the City Mayor sign and date the Letter of Acknowledgement. Please have
Mr. Shane Maloney, Attorney for City of Renton, Washington, complete and sign the
Certificate of Authority. Attach a signed copy of the City resolution(s) and/or
April 30, 2026 Cover Letter

delegations of authority that authorize the City Mayor and City Attorney to execute the
subject documents in connection with the CED-01-26 levee repair project. In the event
a designee signs the documents, please provide supporting documentation for the
delegation of authority for the designee to sign for the City Mayor. Return the signed
acknowledgement letter and signed resolution to us in the postage-paid envelope
provided by May 15, 2026, or sooner. Solicitation for construction is currently
scheduled for June 1, 2026.
Enclosure 5 is the Certification of Lands and Authorization for Entry with Exhibit
A map, and an attorney’s Title Certificate/Third Party Analysis -- in duplicate. In order to
support the proposed levee rehabilitation effort, the City of Renton will need to certify
Perpetual Flood Protection Levee Easements, as well as certify the Temporary Access
Easement routes for the Operations & Maintenance (O&M) access route as shown on
the project map (See Enclosure 5, Exhibit A map). Please have the City Mayor, or an
authorized designee, sign page two (2) of the enclosed Certification of Lands and have
the City’s Attorney, complete and sign the Title Certificate. Retain one original copy of
each document for the City’s records and return the second signed set of original
documents in the envelope provided. The signed Letter of Acknowledgement (Encl #4)
and LER Certification documents (Encl #5) may be returned to us as a complete
package, if available.
The signed certification documents will certify that the City owns or controls a
sufficient interest in the lands necessary to execute the proposed levee rehabilitation
project and will grant the Government permission to enter upon those lands for project
purposes. When you return the Certification package with signatures as outlined above,
please include the necessary supporting documentation, i.e., Title Reports, Perpetual
Flood Protection Levee Easement deeds and the Temporary Work Area Easement that
are necessary to accomplish the currently proposed repairs, as outlined on the
spreadsheet provided as part of Exhibit A.
We must determine that property interests provided by the City sufficiently cover
the project lands before the Chief of Real Estate can certify the lands available for
project purposes. The Chief of Real Estate Division’s Certification must be
accomplished before the construction contract award can occur.

Dear Mr. Farah,
This letter is to inform the City of Renton, of the estimated minimum real estate
interests required to support the Cedar River Left Bank Authorized Federal Levee.
Given the stringent timelines of the PL84-99 program, your office should begin working
to identify, secure, and make available to USACE, the necessary interests. While there
is no obligation to acquire these interests prior to execution of the Cooperation
Agreement, it is highly unlikely that the project will be successful if real estate is not
secured in advance.
Enclosed is the LERRD (Lands, Easements, Right of Ways, Relocations, and
Disposals) Package with complete instructions and schedule on the required real estate
interests to be acquired by City of Renton. Please return the completed LERRD
Package no later than 0D\, 2026.
If you have any questions regarding real estate, please contact the Realty
Specialist assigned to this project, Katelyn Pang at 206-798-6855 or at
katelyn.a.pang@usace.army.mil and Real Estate Team Lead, Omar Vega at 206-291-

PART 1. EXECUTIVE SUMMARY
PROJECT NAME: Cedar Authorized Left Bank Levee
PROJECT FUNDING CLASS: 310
PROJECT CWIS NUMBER: 094283
NON-FEDERAL SPONSOR: City of Renton
LOCATION AND DESCRIPTION: The Cedar Authorized Left Bank Levee is in King
County, WA, along the left bank of the Cedar River near Boeing Field in Renton. It is an
approximately 6,400 foot long earthen levee combined with steel and concrete floodwalls
and closure structures. Most of the levee segment is armored with Class I -IV riprap, while
other sections are comprised of a concrete floodwall with sheet pile underground. The levee
system contains a closure structure, operated by Boeing, that is associated with the level of
protection of the levee. In its undamaged state, the levee provides a 120-year level of
protection for residential, commercial, and industrial property and the Renton Municipal
Airport. This level of protection corresponds to 0.0083 Annual Exceedance Probability
(AEP).
DESCRIPTION OF DAMAGE: In early December 2025, Western Washington experienced
several atmospheric river events that brought prolonged and substantial rainfall, leading to an
increased flow in the Cedar River. The river peaked above major flood stage at the USGS
gage 12119000 near Renton, WA, located approximately 0.6 miles upstream of the damaged
portion of the levee. The flood caused the topsoil to strip away from the bank armoring and
displaced riprap for 1,000 linear feet (LF) around the South Boeing Bridge. There are several
scoured out areas from the toe to the floodwall. In its damaged state, the section of the levee
will provide approximately a 3-year level of protection (0.33 AEP).
PROPOSED REPAIR: Repair in-kind is recommended to restore the overall levee segment
to its pre-damage level of protection. The displaced riprap and loose material will be
removed, and the riverward slope (2H:1V) will be reconstructed with a blanket of Class III
riprap. The total length of repair will be 1,000 LF including transitions. Anticipated project
costs and the calculated Benefit/Cost ratio are summarized in Table 1. See Sections 9 and 10
for further discussion of the proposed repair.

Total Construction Cost $843,000

Project Average Annual Benefits $5,013,300
Project Average Annual Costs $40,909
Benefit/Cost Ratio 122.55
1 The estimated costs for E&D exceed the policy threshold of 6% for E&D, as set under
Standard Limits for Costs in ER 500-1-1. Para 5-2. RIP Policy, V(5). The Policy was set
forth in 2001, over twenty years ago, and experience within the Seattle District AOR
supports that a higher percentage is necessary to timely execute projects with construction
costs greater than $100,000 given the increasingly complex regulatory environment where
the project is located. The Seattle District is requesting an exception to this standard limit
based on its extensive experience with costs for this type of work to manage the risks
inherent to executing projects in the district.

4. Project Location
The levee is located along the left bank of the Cedar River in Renton, WA in Section 7,17,18,
Township 23, Range 05. The project starts at river mile (RM) 0.0 and ends at RM 1.3 and is
approximately 6,400 feet long. The upstream end of the levee ties into high ground near the
Wells Avenue Bridge and the downstream portion of the levee ends at the mouth of the
Cedar River where it flows into Lake Washington.
5. Project Design
The levee segment is a combination of earthen embankment and concrete floodwall with
embedded sheet pile. The levee has riverward and landward slopes of 2H:1V with a height of
4-6 ft. The floodwall section of the levee is 3-9 feet tall. The top width of the floodwall is 1
ft, and the earthen embankment is 10-12 feet wide with asphalt and grass covering the crown.
From station (STA) 0+00 to 19+00 the levee is designed to overtop during events greater
than the design flood to prevent other areas from overtopping. There are closure structures
that are annually exercised by Boeing. Existing encroachments have been approved by
USACE. Several culverts penetrate the levee prism along the length of the alignment and
have been inspected by the inspection team. The levee protects residential, commercial, and
industrial property and the Renton Municipal Airport. In undamaged conditions, the levee
provides protection for a 120-year event.

6. Disaster Incident
In early December 2025, Western Washington experienced several atmospheric river events
that brought prolonged and substantial rainfall. USGS Gage 12119000 is located
approximately 180 feet downstream of a bridge on Bronson Way South, and approximately
0.2 miles from SR 900/ Interstate 405 in Renton. The damage section of the levee is 0.3
RM’s upstream from the USGS gage. This gage has discharge records from 1907 to date.
The peak of the flood event occurred on 11 December with a flow of 12,500 cfs. These
recorded flows represent approximately a .005 AEP (200-year return interval). See Appendix
C for more details.
7. Project Damages
The flood event from December 2025 had significant impacts on the levee system. The levee
experienced erosion at the toe of the floodwall near the upstream (STA 39+50 to 46+50) and
downstream (STA 35+50 to 38+50) sides of the south Boeing Bridge. The highwater stripped
the topsoil from the bank armor and displaced riprap for approximately 1,000 LF. The bank
armoring has also been scoured from the toe to the floodwall in several locations. The most
significant damage is near STA 39+50 where the riprap coverage is discontinuous, leaving
the underlying embankment materials exposed in several areas. The rest of the levee is in
generally good condition as noted by USACE inspectors.
Prior to the damage, the levee provided a 120-year level of protection (0.008 AEP).
However, following the flood-induced damage, this section of the levee is now expected to
provide approximately a 3-year level of protection (0.33 AEP). The post-flood level of
protection assessment tool included in the PL 84-99 Levee Rehabilitation Program Guidance
Memorandum, dated 19 January 2022, was used in the evaluation of the Cedar Authorized
Left Bank Levee damages. The damaged state level of protection was determined from the
2026 Rapid Assessment Levee Evaluation Report. The memorandum provides specific
instructions for determining the levels of protection for eligible levees and the processes for
determining the damaged levels of protection.

9. Project Repair Alternatives Considered
Viable alternatives must restore reliable flood protection to the level of protection existing
prior to damage, must be environmentally acceptable, and can be constructed prior to the
next flood season. The recommended alternative must be the least cost alternative that
restores the level of protection while fulfilling all legal, technical and environmental

requirements. A preliminary evaluation has been performed on the alternatives discussed
below.
a. No Action
The No Action alternative was evaluated and rejected due to the reduced level of protection
and the increased likelihood of increased damage or breach of the levee in its current
condition. This alternative does not restore flood protection and is not acceptable from a
technical perspective, nor is it acceptable to the non-Federal sponsor.
b. Non-Structural Alternative
This alternative would relocate all existing structures, utilities and other infrastructure within
the damaged area protected by the levee. This alternative is not acceptable to the non-Federal
sponsor because the cost to implement this alternative is too high when compared to that for
other alternatives.
c. Repair In-Kind
The Repair In-Kind alternative would reconstruct the riverward slope within the pre-
damaged footprint. This approach would reestablish the toe, regrade the riverward slope to
2H:1V, and then armor with riprap. Total construction length, including transitions, would be
1,000 LF (STA 35+50 to 38+50 and STA 39+50 to 46+50). This approach is considered the
most acceptable for technical reasons and is the least cost option.
10. Recommended Alternative
For the purpose of this PIR, the recommended alternative is Repair In-Kind, which would
restore the overall levee to its pre-damaged level of protection. The repair will restore the
riverward slope of the floodwall to its pre-damage geometry and provide continuous
armoring from the toe to the base of the floodwall. The damaged section of the riverward
slope will be stripped of loose and undermined soil, then built to establish the design cross
section. The rebuilt slope will be graded to a slope of 2H:1V with a 2.5 feet thick blanket of
Class III riprap. Total length of repair will be 1,000 LF including the transitions. The
recommended alternative is shown in Appendix E.
11. Real Estate: Lands, Easements, Rights-of-Way, Relocation, and Disposal (LERRD’s)
In order to proceed with the rehabilitation effort, the non-Federal sponsor must make the
required local project lands available prior to solicitation for the construction contract. To
meet the real estate requirements, the non-Federal sponsor will need to demonstrate that it
has the minimum real property interests, listed below, for the rehabilitation project footprint:
Note that this is template language and relevant detail (e.g. tract numbers) will be provided in
the Engineering and Design phase.

As part of the land certification process for the levee rehabilitation effort, the non-Federal
sponsor will need to provide recent title reports demonstrating its interest in the Levee
Project repair site.
Any questions regarding types of property interests needed for the proposed project should
be coordinated with the U.S. Army Corps of Engineers (Corps), Real Estate Division.
12. Economic Evaluation
a. Study Area
The Cedar Authorized Left Bank Levee is a 6,400-foot-long earthen levee with concrete
floodwalls located on the left bank of the Cedar River in King County, Washington. Prior to
sustaining damage, the levee provided a 120-year level of flood protection for residential,
commercial, industrial property, and the Renton Municipal Airport. However, in December
2025, the levee's integrity was compromised by severe flooding caused by a series of
atmospheric rivers. The flood event stripped topsoil from the bank armoring and displaced
riprap for 1,000 linear feet, causing several scoured-out areas from the toe to the floodwall.
As a result of this damage, the levee's level of protection has been critically reduced from a
120-year event (0.0083 AEP) to an approximately 3-year event, which corresponds to a 0.33
Annual Exceedance Probability (AEP).
b. General
Based on official guidelines (EP 500-1-1, Appendix D), the economic life of a Federal Urban
Project is defined as the shortest of the following three periods. (1) Fifty years. (2) The
degree of protection afforded by the project. (3) The project's remaining lifespan with normal
maintenance, but without major repairs to key parts like pumps or levees.
Applying these criteria to this project, the repairs will restore the levee to a 120-year level of
protection, meaning it can withstand a flood with a 0.83% chance of occurring in any given
year. The project's remaining life is considered to be 120 years. When compared with the
maximum 50-year period, the 50-year lifespan is the shortest and therefore the most limiting
factor. Consequently, the period of analysis for this evaluation is 50 years.
All project costs and benefits are calculated using October 2025 (FY26) price levels. These
figures are then annualized over the 50-year analysis period using the current Federal
discount rate of 3.25% for water resources projects.
c. Without-Project (W/OP) Condition
Under the Without-Project (W/OP) condition, the levee’s level of protection is assumed to
decline from a 120-year event (a flood with a 0.83% annual chance of occurrence, or 0.0083
AEP) to a 3-year event (a flood with a 33.33% annual chance of occurrence, or 0.33 AEP).
PROJECT INFORMATION REPORT
REHABILITATION OF FLOOD CONTROL WORKS
CED-01-26
8
Although no flood-related fatalities have been reported in the area, this reduced level of
protection increases the potential risk to human life.
d. With-Project (WP) Condition
Under the With-Project (WP) condition, repairing the levee would restore the structure to its
pre-damage level of protection, which is a 120-year event (a flood with a 0.83% annual
chance of occurrence, or 0.0083 AEP).
e. Project Costs
The project's total construction cost is $843,000, which includes supervision and
administration (S&A), and contingency. Adding the estimated $100,000 for engineering and
design brings the total project first cost to $943,000. Table 2 provides a detailed breakdown
of these costs.
Table 2: Project Costs
Cost Items Amounts ($)
Construction Cost $722,900
S & A (6%) $43,400
Contingency (10% of Construction + S&A) $76,700
Total Construction Cost $843,000
Engineering and Design (6% Total Construction, see Section 10) $100,000
Total Project First Cost $943,000
The total project investment cost is $943,000, which consists of the project's first costs and
interest during construction. Interest during construction was not included (considered $0), as
the construction period is expected to be minimal (not more than three months). To compare
costs with the project's benefits, the total project costs are annualized and compared with the
expected annual damages avoided which are equivalent to the average annual equivalent
benefits. These costs are amortized over the project's 50-year life. Table 3 presents the
annualized project costs and benefits.
Table 3: Annual Costs
Cost Items Amounts ($)
First Cost $943,000
Interest During Construction (IDC) $0
Total Project Investment Costs $943,000
Average Annual Equivalent (AAEQ) Investment Costs $38,409
AAEQ Operations and Maintenance Costs $2,500
Average Annual Equivalent Costs (AAEQ Costs) $40,909
PROJECT INFORMATION REPORT
REHABILITATION OF FLOOD CONTROL WORKS
CED-01-26

The IWR Planning Suite II was used to calculate the average annual equivalent (AAEQ)
costs. The AAEQ investment cost is approximately $38,409, with an additional estimated
$2,500 AAEQ Operations and Maintenance (O&M) cost. This results in a total AAEQ cost to
approximately $40,909.
f. Benefits Evaluation
In accordance with ER 500-1-1, economic analysis has been prepared at a level of detail
commensurate with the project's complexity, which is sufficient to demonstrate a high
probability that the annualized benefits of the levee repair will exceed the annualized costs.
Flood risk damages were estimated by constructing an expected damage–probability curve,
which plots estimated damages against the probability of exceedance for flood events. The
area under this curve represents the probability-weighted sum of damages, commonly
referred to as Expected Annual Damage (EAD). Project benefits are calculated as the
reduction in EAD, representing the difference between the Without-Project (WOP) and With-
Project (WP) conditions.
Project Benefit = EAD (Without-Project Condition) – EAD (With-Project Condition)
To estimate the EAD under both conditions, several assumptions were applied. The analysis
assumes that all structures affected by flooding are residential. Damages resulting from
inundation depth follow the depth-damage relationship specified in EGM 04-01. A one-foot
inundation depth was assumed, resulting in a 23.3% damage factor applied to structure value
and a 14% damage factor applied to contents value. Furthermore, a structure-to-content value
ratio of 1:1 is assumed. The calculation excludes losses from agricultural flooding when
calculating the EAD reduction. Any project demonstrating a benefit-cost ratio (BCR) greater
than 1.0 under these highly conservative assumptions would likely be even more
economically justified under more realistic scenarios.

EAD With Project $146,800
EAD Damages Reduced $5,013,300
The National Levee Database (NLD)1 was used to estimate potential property damages
within the protected area. According to the NLD, failure of the Cedar Authorized Left Bank
Levee would result in approximately $95.64 million in property damage (FY26 price levels).
These damages would affect 99 structures, and the project would also protect an
estimated 657 residents and zero acres of farmland that would benefit from levee protection.
Before sustaining damage, the levee provided a 120-year level of flood protection for local
industrial and residential properties, corresponding to a 0.0083 AEP event. The damage
reduced the levee’s protection to approximately a 3-year event (0.33 AEP). The proposed
repairs would restore the levee to its original 120-year level of protection. Under the With-
Project (WP) condition, the 0.83% AEP event (120-year flood) is assumed to produce zero
damage, while damages begin accruing at the 0.8265% AEP event (121-year flood).
1 The NLD was developed by USACE as part of the Levee Safety Program (LSP) established in 2006 to assess
levee integrity and identify actions needed to reduce flood risk. Although the NLD can be cumbersome to use, it
provides a valuable screening-level tool for evaluating potential damages in a situation where a manual
infrastructure inventory is not feasible. The LSP utilizes HAZUS to derive the damageable property value. Hazus-
MH is a nationally applicable standardized methodology that estimates potential losses from earthquakes,
hurricane winds and floods.

Using this approach, the Expected Annual Damage (EAD) for the WP condition is estimated
at $146,800 (see the lower portion of Table 4). Under the Without-Project (WOP) condition,
the damaged levee provides only a 3-year level of protection (0.33 AEP). The resulting EAD
for the WOP condition is estimated at $5,160,100 (see the upper portion of Table 4).
Therefore, the project’s annual flood damage reduction benefit, calculated as the difference
between WOP and WP EAD values, is $5,013,300.

The Benefit Cost Ratio (BCR) is 24.51 (see Table 5).

APPENDIX F – ECONOMICS
The economic benefit of this project is quantified by comparing the Expected Annual
Damage (EAD) between two alternatives: the "without-project" (do-nothing) baseline and the
"with-project" scenario. For the purposes of this analysis, the "without-project" alternative is
assigned a 33.33% Annual Exceedance Probability (AEP), equivalent to a 3-year return
period, to establish the baseline EAD. The "with-project" alternative is evaluated against a
0.83% AEP, corresponding to a 120-year level of protection. The "EAD Reduced" represents
the primary annual benefit of this capital investment, calculated as the difference in EAD
between the "without-project" and "with-project" alternatives.

PROJECT INFORMATION REPORT
REHABILITATION OF FLOOD CONTROL WORKS

G-1
APPENDIX G – ENVIRONMENTAL
This appendix is the best assessment given the time and funding limitations when it was
prepared. Further facts and considerations can come to light later in the process (e.g., during
engineering and design) that can change compliance obligations under applicable Federal and
State environmental laws.
Tab G-1
A statement on the effect of proposed work on the environment.
Effects on the quality of the environment resulting from the proposed levee repair are
anticipated to be less than significant.
Tab G-2
Environmental Assessment.
USACE will determine the appropriate level of NEPA review in accordance with section 1.2
of the DoD NEPA Implementing Procedures. These procedures are available online at
https://www.denix.osd.mil/nepa/.
Tab G-3
Considerations under Section 7 of the Endangered Species Act of 1973 (PL 93-205).
Species and critical habitat listed under the Endangered Species Act (ESA) are present in the
project area and could be impacted by the proposed work. Impacts to ESA-listed species and
critical habitat will be evaluated in a Biological Assessment and transmitted to the National
Marine Fisheries Service and U.S. Fish and Wildlife Service for consultation. At this time
USACE anticipates formal consultation will be required with at least one of the Services.
Tab G-4
Archeological Investigations and Salvage Activities considerations.
The proposed project will be reviewed for potential effects to historic properties in
accordance with Section 106 of the National Historic Preservation Act (NHPA), as amended.
Prior to repairs, a Secretary of the Interior qualified individual will conduct research and a
field survey of the project area to identify any historic properties, archeological resources, or
resources that are culturally significant and to determine whether there is a potential for the
proposed project to cause effects.
Tab G-5
Section 404(b) evaluations.
USACE is responsible for the compliance of its civil works projects with Sections 401 and
404 under the Clean Water Act. Based on the level of detail in this PIR, USACE anticipates
that the proposed work is not exempt from regulation under Section 404 and will require
general or individual Section 401 Water Quality Certification.

Tab G-6
A statement on the applicability of EO 11988.
By USACE policy (Engineering Regulation 500-1-1), the provisions of Executive Order
11988 are normally not applicable to the repair of flood control works to the pre-disaster
condition, as the repair actions do not directly affect either the modification or occupancy of
floodplains, and do not directly or indirectly impact floodplain development. The proposed
project does not constitute a major rehabilitation project, require extensive engineering and
design, or significantly change the project footprint and therefore is not required to be
evaluated for its impact on the floodplain.
Tab G-7
A statement on the applicability of the Coastal Zone Management Act.
The Coastal Zone Management Act applies because the proposed work is within the coastal
zone of a coastal county. Therefore, USACE will prepare a Coastal Zone Consistency
Determination showing substantive consistency with the enforceable polices of Washington’s
Coastal Zone Management Program.
Tab G-8
Environmental Enhancement Features.
Project construction may include environmental enhancement features to offset project
impacts. For the recommended plan, details will be developed through required
environmental coordination during E&D.
