Kleinfelder Project # 24001006.001A

Dear Mr. Tibbitts,

Kleinfelder has been tasked by the Sacramento Area Flood Control Agency (SAFCA) with evaluating the seismic vulnerability of the Sacramento area levees located in Sacramento and Sutter Counties, California in support of the Urban Levee of Protection (ULDC) (DWR, 2012) level certification effort. As part of this project, a Post-Earthquake Response Plan (PERP) has been prepared to assist SAFCA in planning a response to earthquake damaged levees. This appendix to the PERP addresses the anticipated effects of a seismic event on the American River South, Sacramento River East, and Beach Lake North levee segments found to have High Vulnerability in the American River South Levee System Seismic Performance Summary Report (SPSR). This includes estimating the amount and extent of damage done to the levee and the approximate quantity of earth material needed to restore the levee to a sufficient level of protection against the 10-year flood, as well as the quantity of material to restore the existing top of levee.

Sincerely,

KLEINFELDER, INC.

E.1 INTRODUCTION
______________________________________________________________________________________________

This appendix contains the Post-Earthquake Remediation Plan (PERP) for the American River South Levee System (ARSLS) levee segments found to have High Vulnerability 1 to seismic loading in
Kleinfelder’s 2025 Seismic Performance Summary Report (SPSR) (Kleinfelder, 2025). As shown in Figure E-1, the major streams of the ARSLS area are the American River and Sacramento River. The study area also includes the Beach Lake North Levee (BLNL) along Morrison Creek. In total, fifteen seismic levee segments in the study area were found to have High Vulnerability, and they are listed below for each levee system:

• American River South Levee (ARSL) contains three High Vulnerability segments:
o Segment 1 (Station 1000+00 to 1135+00)
o Segment 3 (Station 1195+00 to 1335+86)
o Segment 5 (Station 1381+93 to 1431+25)

• Sacramento River East Levee (SREL) contains nine High Vulnerability segments:
o Segment 1 (Station 1000+00 to 1019+00)
o Segment 2 (Station 1019+00 to 1086+00)
o Segment 3 (Station 1086+00 to 1178+00)
o Segment 4 (Station 1178+00 to 1214+00)
o Segment 5 (Station 1214+00 to 1245+00)
o Segment 6 (Station 1245+00 to 1286+00)
o Segment 7 (Station 1286+00 to 1425+00)
o Segment 8 (Station 1425+00 to 1671+00)
o Segment 10 (Station 1707+50 to 1770+00)

• Beach Lake North Levee (BLNL) contains three High Vulnerability segments:
o Segment 1 (Station 987+18 to 993+18)
o Segment 3 (Station 1004+40 to 1034+10)
o Segment 5 (Station 1117+55 to 1136+74)

1 The PERP addresses medium and high vulnerability levees. The ARSLS levees did not include any medium vulnerability levees.

The PERP addresses criteria identified in Section 7.7 Seismic Vulnerability and Section 7.7.1 Intermittently Loaded Levees of the Urban Levee Design Criteria (ULDC) published by the State of California Department of Water Resources (DWR) (DWR, 2012). The subject high vulnerability levees are classified by the Urban Levee Evaluation Project (ULE) (URS, 2015a) as intermittently loaded, as they do not experience a water surface elevation of one foot or higher above the elevation of the levee toe at least once a day for more than 36 days per year on average. For intermittently loaded levees, if seismic damage from 200-year-return-period ground motions is expected, the ULDC requires that a PERP be developed as part of a flood safety plan (FSP) developed in coordination with pertinent local, state, and federal agencies.

The PERP includes an initial estimate of the amount and extent of damage that might be sustained following an earthquake with a 200-year-return-period. It also provides an estimate of the amount of earth and other materials that would be necessary for interim repairs, as well as the amount needed to build the full levee to pre-earthquake crown elevation and ULDC prism dimensions during long-term repair
2 . Borrow sites and haul routes for repair construction were provided by MBK Engineers (MBK).

Per the ULDC, interim repairs are defined as those necessary to restore the levee system’s grade and dimensions within 8 weeks and sufficient for protection against the 10-year flood, with 3 feet of freeboard (referred to herein as the Interim Repair Design Elevation (IRDE)). Levee grade and dimensions for interim repairs have been assumed to equal the minimum levee prism defined in Section

7.7.1 of the ULDC: a crown width of 20 feet for major levees and levee slopes of 3H:1V waterside and landside.

The PERP uses 200-year-return-period ground motions. However, it is acknowledged that earthquakes exceeding the 200-year return period are possible. Although the subject levee system has not been analyzed for such ground motions, it is likely that the potential locations of damage expected from 200- year-return-period ground motions would also be considered the most likely damage locations for more severe ground motions.

2 Long-term levee construction to pre-earthquake crest height with 3H:1V slopes is ideal (and may be superior to the pre-earthquake dimensions due to shallower slopes ) but may be limited depending on available area for construction. Long -term volumes in this PERP are based on the ideal case. At a minimum, long-term levee reconstruction will be to the existing crown elevation and will match existing slope grades if they are steeper than 3H:1V.

E.2 SCOPE
______________________________________________________________________________________________

This Appendix to the PERP only assesses the fifteen ARSLS levee segments with High Vulnerability for seismic failure. The remaining segments were found to have Low Vulnerability and are described further in the SPSR (Kleinfelder, 2025).

This Appendix describes the expected seismically induced damages and failure modes for each of these ARSLS segments along ARSL, SREL, and BLNL. Based on these expected damages, estimates are included for the amount of material required to restore each segment’s grade and dimensions to sufficiently protect against the 10-year flood plus three feet of freeboard, as well as the amount needed to restore the full levee during long-term repairs. The Appendix also examines the causes and effects of potential damages on the levee prism and cutoff walls. For response and repair procedures, refer to Sections 4 through 7 of the main PERP document.

E.3 POTENTIAL SEISMICALLY INDUCED DAMAGES
______________________________________________________________________________________________

As described in the PERP, seismic loading may induce strength losses within the levee and/or foundation, resulting in slumping, vertical displacement, and cracking. Overtopping during high water events can occur when freeboard is lost. As a result, it is necessary to estimate the location and severity of levee failures instigated by a seismic event. The actual degree and patterns of damage will vary with the local soil conditions and seismic response, the magnitude of ground shaking, the groundwater level, and the water level against the levee (if any).

In 2015, the Geotechnical Evaluation Reports (GERs) for the American River (URS, 2015a), Sacramento River (URS, 2015b), and South Sacramento Streams (URS, 2015c) Study Areas evaluated fifteen total segments as having High Vulnerability to a 200-year return period seismic event – which was a magnitude 6.5 and peak horizontal acceleration (PHA) of 0.13g to 0.15g. This classification was due to Likely Liquefiable layers with low residual undrained strengths, which affected the levee strength and stability. Based on the Kleinfelder update of the regional ground motion hazard analysis, the PHA ranges from 0.12g to 0.14g associated with controlling earthquake magnitudes of 6.7 and 6.8 (depending on location) in the ARSLS SPSR (Kleinfelder, 2025). The High Vulnerability segments were not reanalyzed for seismic vulnerability changes, as they would all remain High Vulnerability. Therefore, the 2015 GER models of the segments were used as the basis for estimating the damages.

MBK provided estimates of the ULDC Design Water Surface Elevation (DWSE), Hydraulic Top of Levee (HTOL), and 10-year water surface elevation (WSE) plus 3 feet for the American River and Sacramento River (MBK, 2025). These values are provided in Attachment 1 and were used to determine the interim repair design volumes (Attachments 2 and 3). Existing top of levee elevations were estimated using various sources described in this document and were used to determine the long-term volumes (Attachments 4 through 6).

The GER post-seismic stability analyses show that flow failure is the expected deformation type for all High Vulnerability segments in the ARSLS region. This PERP assumes that if the levee fails along the flow failure planes which have Factor of Safety less than 1.0, the majority of the levee prism and riverbank will be damaged. The volume quantities calculated for this PERP are for a new levee prism built on undamaged riverbank set back from the existing levee.

Section E.3.1 describes the geometry and expected damages for each ARSLS High Vulnerability segment.

Estimates are provided for the amount of material needed to build a new levee to the existing top of levee (long-term) and to the minimum levee prism defined in Section 7.7.1 of the ULDC (interim): a crest at the 10-year WSE plus 3 feet of freeboard (IRDE), a crown width of 20 feet, and levee slopes of at minimum 3H:1V waterside and landside.

According to the ULDC (DWR, 2012), the interim repairs should be sufficient enough to restore an adequate level of flood protection within eight weeks. If seismic damage to the levee system would be so significant and widespread that it would be infeasible to restore the levee to the IRDE grade and dimensions within eight weeks, then seismic strengthening is required to provide the urban level of flood protection.

The MTOL values listed in Attachment 1 are the minimum levee crest elevations required to provide protection against the 200-year flood. The existing top of levee values in Attachments 4, 5, and 6 exceed their corresponding MTOL value by at least 1 foot in elevation. Because the ARSL, SREL, and BLNL feature high freeboard values, repairing the crest to the MTOL would build the levee to a lower elevation than the upstream and downstream crown. Therefore, the long-term volume estimates were calculated using the pre-earthquake existing top of levee elevation instead of the MTOL.

E.3.1 SEGMENT ANALYSES
As shown on Sheet C-1 in the repair schematics of Appendix A of the PERP, in the event of riverbank collapse and/or instability, the levee embankment should be setback on firm, stable ground as directed by the District Engineer. For consistency, this appendix assumes the stable ground elevation for each segment matches the landside toe elevation of the corresponding seismic cross section from the ULE American River GER. The post-seismic slope stability results using these cross sections were used to justify the High Vulnerability classifications originally, so they are considered representative of their corresponding segments. The actual ground elevation is expected to vary across the span of the segment, which would change the total volume estimate.

Construction of a replacement levee prism requires excavation to 3 feet below the original ground surface and 3 feet beyond the projected waterside and landside levee toes. After constructing the new foundation, the interim levee should be rebuilt with at minimum 3H:1V slopes and a 20-foot crown width up to the IRDE. Refer to Details B and C on Sheet C-1 of the PERP.

METHODOLOGY
Attachment 1 contains MBK’s 10-year WSE plus 3 feet (Seismic Vulnerability Restoration Profile – SVRP) elevations for ARSL and SREL at 100-foot intervals. To estimate the total volume of the interim repair levee for each segment, the following steps were performed and the results are shown in Attachments 2 through 6:

• Define the IRDE at each 100-foot “interval” using the 10-year WSE plus 3 feet value. To clarify, the interval labeled “Station 1000+00” represents the levee between Station 1000+00 and 1001+00.
• Since the rebuilt levee would be set back on the riverbank, assume the bottom of the interim repair levee prism is at the landside toe from the corresponding ULE GER seismic cross section. • Estimate the existing top of levee and landside toe elevations for each interval using the most recent information available (for SREL: the 2007 LiDAR survey performed by Fugro West, or the 2024 as-built cross section plan sheets for the American River Common Features SREL projects).

ARSL and BLNL used the crown and landside toe elevations from representative ULE seismic segment cross sections, under the assumption that these elevations were consistent across the segment.
• Calculate the difference between the IRDE and landside toe elevation to the nearest 1 foot for each interval. This is the levee height, denoted as “(d)” in Diagrams 1 and 2 below. • Calculate the cross-sectional area of the ULDC interim levee prism using the equation in Diagram 1 (geometry based on the ULDC requirements):

Diagram 1 – Levee Prism Area Calculation (Square Feet)

• Calculate the cross-sectional area of the foundation using Diagram 2 (geometry based on Sheet C-1 in Appendix A of the PERP):

Diagram 2 – Levee Foundation Area Calculation (Square Feet)

• Multiply each area by 100 feet to calculate the levee volume at each interval, then convert cubic feet to cubic yards. If the interval is not 100 feet due to station limits, adjust the multiplied value accordingly.

a. Example: SREL Segment 10 spans from Station 1707+50 to 1770+00, so the first interval is from Station 1707+50 to 1708+00. The area would be multiplied by 50 feet instead of 100 feet.

b. If the height of the rebuilt levee (“d” in Diagram 1) was equal to or below 1.0 feet, the volume calculation was not performed for that interval. It was assumed that no levee prism would be built in these areas due to high ground. Segments where this occurs are described in their “Volume Estimates” section.

• Sum the interim levee prism and foundation volumes of each interval.

• Round the total volume up to the nearest 1,000 cubic yards to account for variation in levee height across the segment, ramps used during construction, and other uses of additional fill.

The long-term repair volume was estimated similarly to the interim volume. Instead of using the difference between the IRDE and existing landside toe for the height (d) in Diagrams 1 and 2, the difference between the existing top of levee and landside toe elevations was used. The results are shown in Attachments 4 through 6. If unstable subgrade soils are exposed, a suitable, woven, geotextile stabilization fabric or geogrid should be placed. If additional bridging/reinforcement is needed, reinforcing the embankment with a suitable geogrid placed at about a 2-foot vertical spacing for a minimum of three total geogrid layers or as determined by the District Engineer.

As explained on Sheet C-1 in Appendix A of the PERP, in the event of riverbank instability and/or collapse, the levee embankment should be setback on firm, stable ground as directed by the District Engineer. The repair volumes may therefore be greater or smaller than the estimates provided here depending on if the ground elevation is below or above the elevation of the original landside toe.

The aforementioned interim and long-term repair volumes assume the extreme and unlikely scenario where the entire levee prism must be rebuilt due to complete collapse. Based on the volume estimates, this would require obtaining hundreds of thousands of cubic yards of suitable levee material for timely construction. A post-seismic deformation analysis was performed using FLAC 2D on a critical ARSLS cross section, SREL Station 1471+30, to estimate more realistic seismic deformation shape and values of the levee. The results of this analysis were discussed in the SPSR and indicated that sufficient river bank will remain for levee reconstruction.

SEGMENT ARSL-1 (13,500 FEET LONG)
ARSL Segment 1 (Station 1000+00 to 1135+00) extends from the confluence of the American and Sacramento Rivers to Sutter’s Landing Regional Park. In the American River Study Area Geotechnical Evaluation Report (GER), the existing levee geometry for the segment is described as follows (URS, 2015a):

• Levee crown width: 20 feet
• Approximate waterside slope: 3H:1V
• Approximate landside slope: 2.5H:1V
• Approximate levee height: 13 feet

The GER post-seismic stability analysis for Segment 1 calculates a minimum Factor of Safety (FOS) of

0.30 for the waterside slope and 1.08 for the landside slope. Due to the levee’s proximity to the American River, it is expected the levee will be affected by flow failure and the prism would require reconstruction.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated using Figure F-S1-3 from the American River GER Volume 2 (URS, 2015a). This figure is a post-seismic stability analysis cross section at Station 1034+72 used for the segment seismic vulnerability evaluation in the GER. Because the levee geometry described above is assumed consistent across the segment in the GER, the existing levee crown and landside toe were estimated to the nearest 0.01 feet using Bluebeam’s scale and measurement tools and used for every interval of Segment 1.

Volume Estimates
The estimated volumes to construct interim and long-term replacement levees were calculated using the procedure described in the Methodology section. The interval calculations are included in Attachments 2 and 4. Volumes for the interim levee construction, the additional volume to build to the existing top of levee, and the total long-term levee volume are listed in the table below.

ARSL Segment 3 (Station 1195+00 to 1335+86) extends from the Union Pacific Railroad Bridge to approximately 100 feet north of Guy West Bridge. In the American River GER, the existing levee geometry for the segment is described as follows (URS, 2015a):

• Levee crown width: 25 feet
• Approximate waterside slope: 3H:1V or flatter
• Approximate landside slope: 2H:1V or flatter
• Approximate levee height: 14 feet

The GER post-seismic stability analysis for Segment 1 calculates a minimum FOS of 0.33 for the waterside slope and 1.16 for the landside slope. Due to the levee’s proximity to the American River, it is expected the levee will be affected by flow failure and the prism would require reconstruction.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated using Figure F-S3-3 from the American River GER Volume 2 (URS, 2015a). This figure is a post-seismic stability analysis cross section at Station 1206+15 used for the segment seismic vulnerability evaluation in the GER. Because the levee geometry described above is assumed consistent across the segment in the GER, the existing levee crown and landside toe were estimated to the nearest 0.01 feet using Bluebeam’s scale and measurement tools and used for every interval of Segment 3.

SEGMENT ARSL-5 (4,932 FEET LONG)
ARSL Segment 5 (Station 1381+93 to 1431+25) extends from approximately 30 feet west of the Howe Avenue Bridge to approximately 20 feet east of Occidental Drive. In the American River GER, the existing levee geometry for the segment is described as follows (URS, 2015a):

• Levee crown width: 25 feet
• Approximate waterside slope: 3.5H:1V or flatter
• Approximate landside slope: 2H:1V or flatter
• Approximate levee height: 12 feet

The GER post-seismic stability analysis for Segment 1 calculates a minimum FOS of 0.98 for the waterside slope and 2.08 for the landside slope. Due to the levee’s proximity to the American River, it is expected the levee will be affected by flow failure and the prism would require reconstruction.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated using Figure F-S5-3 from the American River GER Volume 2 (URS, 2015a). This figure is a post-seismic stability analysis cross section at Station 1388+00 used for the segment seismic vulnerability evaluation in the GER. Because the levee geometry described above is assumed consistent across the segment in the GER, the existing levee crown and landside toe were estimated to the nearest 0.01 feet using Bluebeam’s scale and measurement tools and used for every interval of Segment 5.

DRAFT

SEGMENT SREL-1 (1,900 FEET LONG)
SREL Segment 1 (Station 1000+00 to 1019+00) extends from the confluence of the American and Sacramento Rivers to the end of the Matsui Park seepage berm. In the 2015 URS Sacramento River Study Area GER, the existing levee geometry for the segment is described as follows (URS, 2015b):

• Levee crown width: 20 to 100 feet
• Approximate waterside slope: 1.4H:1V or flatter
• Approximate landside slope: 2.0H:1V or flatter
• Approximate levee height: 5 to 14 feet

The GER post-seismic stability analysis for Segment 1 at Station 1005+00 calculates a minimum FOS of

0.53 for the waterside slope and 1.53 for the landside slope. The analysis waterside failure plane extends from the landside toe and includes the full levee prism and the riverbank beneath it. Due to the levee’s proximity to the American River, it is expected the levee in this segment will be affected by bank collapse and the prism would require reconstruction on stable riverbank. Levee within the extents of the Matsui Park seepage berm (Station 1013+00 to 1019+00) may have less vulnerability to full collapse due to increased crown widths and landside toe elevations.

Levee Crown and Landside Toe Estimates
Unlike the American River South Levee seismic segments, SREL varies considerably in levee height within each seismic segment. As such, the existing crown and landside toe estimates from the segment’s GER post-seismic cross section were not considered representative of the whole segment, and a more rigorous approach was used to estimate these values for each interval.

Levee crown and landside toe elevations were estimated from the approximate levee crest and landside levee toe profile lines from the Kleinfelder 2022 SREL Geotechnical Data Report (GDR). These profiles were created using LiDAR survey results performed by Fugro West in 2007 under the DWR ULE program (Kleinfelder, 2022).

Volume Estimates
The estimated volumes to construct interim and long-term replacement levees were calculated using the procedure described in the Methodology section. The interval calculations are included in Attachments 3 and 5.

Between Station 1009+00 and 1019+00, the IRDE was at a lower elevation than the existing landside toe. No interim levee was required for this span of levee, and interim repair volumes were not calculated.

Between Station 1012+00 and 1016+00, the landside toe was estimated to be within 0 to 1 feet of the existing top of levee. As shown in Attachment 5, long-term volume was not calculated for this span of levee.

SEGMENT SREL-2 (6,700 FEET LONG)
SREL Segment 2 (Station 1019+00 to 1086+00) spans the Old Sacramento area, including a 10- to 20- foot-high concrete gravity floodwall from Station 1040+00 to 1081+00. In the Sacramento River GER, the existing levee geometry for the segment is described as follows (URS, 2015b):

• Levee crown width: Greater than 100 feet
• Approximate waterside slope: 1.4H:1V or flatter
• Approximate landside slope: 2.0H:1V, but generally high ground • Approximate levee height: 0 to 6 feet

Segment 2 is characterized by a crown width greater than 100 feet and the presence of high ground on the landside, so the segment does not feature a traditional levee prism. URS ran a waterside post- seismic analysis at Station 1028+00. The modeled failure planes shown in the GER (minimum FOS 0.30) DRAFT

extend through the sand riverbank down to approximately 80 feet below the crown elevation. The shape of these failure planes indicate most of the levee crown will be damaged by bank collapse.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated from two sources that used the 2007 LiDAR survey performed by Fugro West. Elevations for Station 1019+00 to 1050+00 were pulled from the approximate levee crest and landside levee toe profile lines from the 2022 GDR. Because the GDR did not feature profiles from Station 1050+00 to 1150+00, the crown and toe elevations for Station 1051+00 to 1086+00 were estimated from the LiDAR & Bathymetry plates in the Supplemental Geotechnical Data Report (SGDR) for the ULE Sacramento River Study Area (URS, 2011); these plates use 2-foot contour lines developed using the same 2007 survey, so elevations were estimated to the nearest 2 feet.

Volume Estimates
The estimated volumes to construct interim and long-term replacement levees were calculated using the procedure described in the Methodology section. The interval calculations are included in Attachments 3 and 5. Volumes for the interim levee construction, the additional volume to build to the existing top of levee, and the total long-term levee volume are listed in the table below.

The landside toe was estimated to be above or at most 1 foot above the IRDE at the following stations, so no interim repair volume was calculated for their intervals:

• Station 1019+00 to 1024+00
• Station 1033+00 to 1042+00
• Station 1051+00 to 1060+00
• Station 1075+00 to 1085+00

DRAFT

24001006.001A/SAC24R167155 Page 15 of 34 April 18, 2025 © 2025 Kleinfelder www.kleinfelder.com
Additionally, no long-term volume was calculated for intervals where the levee landside toe was within 1 foot of the existing top of levee:

• Station 1021+00
• Station 1035+00
• Station 1037+00
• Station 1038+00
• Station 1081+00 to 1085+00

These areas should still be investigated for cracking and slumping to determine an adequate level of flood protection remains if no new prism is constructed.

SEGMENT SREL-3 (9,200 FEET LONG)
SREL Segment 3 (Station 1086+00 to 1178+00) extends from approximately 500 feet south of Pioneer Landing Park to approximately 400 feet south of the City of Sacramento Water Collector No. 1 control structure. In the Sacramento River GER, the existing levee geometry for the segment is described as follows (URS, 2015b):

• Levee crown width: 33 to 145 feet
• Approximate waterside slope: 1.5H:1V or flatter
• Approximate landside slope: 1.6H:1V or flatter
• Approximate levee height: 10 to 20 feet

The GER post-seismic stability analysis for Segment 3 at Station 1168+00 calculates a minimum FOS of

0.39 for the waterside slope and 0.77 for the landside slope. Since these failure planes extend through and below the levee prism and riverbank, flow failure and full levee reconstruction are expected for this segment.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated from two sources that used the 2007 LiDAR survey performed by Fugro West. Elevations for Station 1019+00 to 1050+00 were estimated from the LiDAR & Bathymetry plates in the ULE Sacramento River Study Area SGDR (URS, 2011); these plates use the same 2007 survey as the GDR, which did not have profile lines for Station 1050+00 through DRAFT

The landside toe was estimated to be within 1 foot of the IRDE at the following stations, so no interim repair volume was calculated for their intervals. Long-term construction to existing top of levee is still required for these intervals.

• Station 1091+00 to 1094+00
• Station 1163+00 to 1164+00

SEGMENT SREL-4 (3,600 FEET LONG)
SREL Segment 4 (Station 1178+00 to 1214+00) extends from approximately 400 feet south of the City of Sacramento Water Collector No. 1 control structure to Sutterville Road. In the Sacramento River GER, the existing levee geometry for the segment is described as follows (URS, 2015b):

• Levee crown width: 30 to 100 feet
• Approximate waterside slope: 1.5H:1V or flatter
• Approximate landside slope: 1.8H:1V or flatter
• Approximate levee height: 14 to 29 feet

The GER post-seismic stability analysis for Segment 4 at Station 1195+00 calculates a minimum FOS of

0.80 for the waterside slope and 1.27 for the landside slope. The crown width is noted to be closer to 30 feet from Station 1178+00 to 1188+00 and 1201+00 to 1214+00 (2,300 feet) and closer to 100 feet for DRAFT

Station 1188+00 to 1200+00 (1,300 feet). Since failure is only expected for the waterside, it is possible the 100-foot-crown portion of the segment may have enough remaining flood protection to meet ULDC.

This PERP assumes the levee will be rebuilt for the entire segment as a conservative estimate.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations for Station 1178+00 to 1214+00 were estimated from the approximate levee crest and landside levee toe profile lines from the 2022 GDR.

SEGMENT SREL-5 (3,100 FEET LONG)
SREL Segment 5 (Station 1214+00 to 1245+00) extends from approximately Sutterville Road to the Westin Hotel. In the Sacramento River GER, the existing levee geometry for the segment is described as follows (URS, 2015b):

• Levee crown width: 100 to 200 feet
• Approximate waterside slope: 1.8H:1V or flatter
• Approximate landside slope: 2.1H:1V or flatter
• Approximate levee height: 9 to 20 feet

The GER post-seismic stability analysis for Segment 5 at Station 1235+00 calculates a minimum FOS of

0.58 for the waterside slope and 0.85 for the landside slope. Despite the large crown width, the failure planes of this analysis show that most of the levee prism will be damaged from bank collapse. The DRAFT

remaining levee prism should be inspected after the earthquake to determine if enough levee remains and meets ULDC flood protection dimensions.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations for Station 1214+00 to 1245+00 were estimated from the approximate levee crest and landside levee toe profile lines from the 2022 GDR.

SEGMENT SREL-6 (4,100 FEET LONG)
SREL Segment 6 (Station 1245+00 to 1286+00) is located within the Little Pocket area and extends from the Westin Hotel to Bahnfleth Park. In the Sacramento River GER, the existing levee geometry for the segment is described as follows (URS, 2015b):

• Levee crown width: 17 to 39 feet
• Approximate waterside slope: 1.3H:1V to 3H:1V
• Approximate landside slope: 1.9H:1V to 3.2H:1V
• Approximate levee height: 9 to 20 feet

The GER post-seismic stability analysis for Segment 6 at Station 1254+92 calculates a minimum FOS of

0.43 for the waterside slope and 0.77 for the landside slope. The failure planes of this analysis show that the entire levee prism and the riverbank beneath it will likely be damaged from bank collapse, and full levee reconstruction will be necessary.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated from two sources. Station 1245+00 to 1263+00 elevations were estimated from the December 2024 SREL-4 project as-built plan sheets C-303 to C-305 (Odin Construction Solutions, 2024b). These plan sheets displayed levee cross sections at 100-foot intervals up to Station 1263+00 and were considered the most recent and accurate sources for crest and toe elevations for this segment. The remaining elevations from Station 1264+00 to Station 1286+00 were estimated from the approximate levee crest and landside levee toe profile lines from the 2022 GDR.

SEGMENT SREL-7 (13,900 FEET LONG)
SREL Segment 7 (Station 1286+00 to 1425+00) extends for over 2 miles of the Pocket area, from approximately Bahnfleth Park to Sump 70. In the Sacramento River GER, the existing levee geometry for the segment is described as follows (URS, 2015b):

• Levee crown width: 16 to 57 feet
• Approximate waterside slope: 1.5H:1V to 3.3H:1V
• Approximate landside slope: 2.1H:1V to 3.4H:1V
• Approximate levee height: 8 to 19 feet

No post-seismic stability analysis was performed for Segment 7 in the GER. Segment 7 was considered High Vulnerability due to similar geometry and stratigraphy to SREL Segment 6 (URS, 2015b). Based on the post-seismic analysis for Segment 6, it is assumed that the entire levee prism and the riverbank DRAFT

24001006.001A/SAC24R167155 Page 20 of 34 April 18, 2025 © 2025 Kleinfelder www.kleinfelder.com
beneath it will likely be damaged from bank collapse, and full levee reconstruction across Segment 7 will be necessary.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated from multiple sources:

• As with SREL Segment 6, the elevations from Station 1286+00 to 1300+00 and 1400+00 to 1423+00 were estimated from the approximate levee crest and landside levee toe profile lines from the 2022 GDR.
• Because the GDR did not feature profiles for Station 1300+00 to 1400+00, the elevations for these stations were estimated from the LiDAR & Bathymetry plates in the ULE Sacramento River Study Area SGDR (URS, 2011).
• Finally, the elevations at Stations 1424+00 and 1425+00 were estimated from the 2024 SREL-3 project as-built plan sheet C-701, which displays levee cross sections at 100-foot intervals (Odin Construction Solutions, 2024a).
o These cross sections call out the as-built elevations of the crown landside and waterside endpoints to the nearest 0.01 feet (in example, 35.23 feet landside and 35.28 feet waterside at Station 1424+00). The crown elevation was rounded to the nearest 0.1 feet using these values. The landside toe elevation value was not called out on the cross sections, so it was estimated to the nearest 1 foot.

Volume Estimates
The estimated volumes to construct interim and long-term replacement levees were calculated using the procedure described in the Methodology section. The interval calculations are included in Attachments 3 and 5. Volumes for the interim levee construction, the additional volume to build to the existing top of levee, and the total long-term levee volume are listed in the table below.

SEGMENT SREL-8 (24,600 FEET LONG)
SREL Segment 8 (Station 1425+00 to 1671+00) extends throughout the remainder of the Pocket area, from approximately Sump 70 to the Freeport Regional Water Facility. In the Sacramento River GER, the existing levee geometry for the segment is described as follows (URS, 2015b):

• Levee crown width: 15 to 60 feet
• Approximate waterside slope: 1.7H:1V or flatter
• Approximate landside slope: 1.8H:1V or flatter
• Approximate levee height: 12 to 19 feet

No post-seismic stability analysis was performed for Segment 8 in the GER. Segment 8 was considered High Vulnerability due to similar geometry and stratigraphy to SREL Segment 6 (URS, 2015b). Based on the post-seismic analysis for Segment 6, as well as the logic used for Segment 7, it is assumed that the entire levee prism and the riverbank beneath it will likely be damaged from bank collapse, and full levee reconstruction across Segment 8 will be necessary.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated from multiple sources.

• Continuing from SREL Segment 7, the elevations for Station 1425+00 to 1529+00 were estimated from the 2024 SREL-3 project as-built plan sheets C-701 through C-708, which display levee cross sections at 100-foot intervals (Odin Construction Solutions, 2024a). • The elevations for Station 1530+00 to 1535+00 were estimated from the 2024 SREL-4 project as- built plan sheet C-306, which displays levee cross sections at 100-foot intervals (Odin Construction Solutions, 2024b).
• The elevations for Station 1535+00 to 1550+00 and 1600+00 to 1671+00 were estimated from the approximate levee crest and landside levee toe profile lines from the GDR (Kleinfelder, 2022).
• Because the GDR did not feature profiles for Station 1550+00 to 1600+00, the elevations for Stations 1551+00 to 1599+00 were estimated from the LiDAR & Bathymetry plates from the ULE Sacramento River Study Area SGDR (URS, 2011).

SEGMENT SREL-10 (6,250 FEET LONG)
SREL Segment 10 (Station 1707+50 to 1770+00) is located in the Freeport area, extending up to the interface of the Beach Lake North Levee. Segment 9 was considered Low Vulnerability due to lack of liquefiable layers, so it is not discussed in this PERP (Kleinfelder, 2025). In the Sacramento River GER, the existing levee geometry for the segment is described as follows (URS, 2015b):

• Levee crown width: 20 to 70 feet
• Approximate waterside slope: 2.4H:1V or flatter
• Approximate landside slope: 2H:1V or flatter
• Approximate levee height: 10 to 17 feet

The GER post-seismic stability analysis for Segment 6 at Station 1254+92 calculates a minimum FOS of

0.84 for the waterside slope and 1.34 for the landside slope. The waterside failure plane of this analysis shows that most of the levee prism will likely be damaged from bank collapse, and full levee reconstruction will be necessary.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated from the December 2024 SREL-4 project as- built plan sheets C-311 through C-318.

SEGMENT BLNL-1 (600 FEET LONG)
BLNL Segment 1 (Station 987+18 to 993+18) begins at the intersection of BLNL and SREL and has a 90- degree bend approximately 450 feet east of the intersection. In the South Sacramento Streams Study Area GER, the existing levee geometry for the segment is described as follows (URS, 2015c):

• Levee crown width: 15 to 35 feet
• Approximate waterside slope: 3H:1V to 4H:1V
• Approximate landside slope: 2H:1V to 2.5H:1V
• Approximate levee height: 10 to 12 feet

The GER post-seismic stability analysis for Segment 1 calculates a minimum Factor of Safety (FOS) of

0.77 for the waterside slope and 1.01 for the landside slope. Due to the shape and extent of the waterside slope stability failure plane, it is expected the levee will be subjected flow failure and the prism will require reconstruction.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated using Figure C-S1-3 from the South Sacramento Streams GER Volume 2 (URS, 2015c). This figure is a post-seismic stability analysis cross section at Station 992+07 used for the segment seismic vulnerability evaluation in the GER. Because the levee geometry described above is assumed consistent across the segment in the GER, the existing levee DRAFT

24001006.001A/SAC24R167155 Page 24 of 34 April 18, 2025 © 2025 Kleinfelder www.kleinfelder.com
crown and landside toe were estimated to the nearest 0.01 feet using Bluebeam’s scale and measurement tools and used for every interval of Segment 1.

Volume Estimates
The estimated volumes to construct interim and long-term replacement levees were calculated using the procedure described in the Methodology section. According to MBK, the 10-year WSE for Morrison Creek is 12.6 feet per NAVD88 for the entire extent of BLNL. Therefore, the IRDE was consistently 15.6 feet for every segment of BLNL.

The calculations are included in Attachment 6. Volumes for the interim levee construction, the additional volume to build to the existing top of levee, and the total long-term levee volume are listed in the table below.

SEGMENT BLNL-3 (2,970 FEET LONG)
BLNL Segment 3 (Station 1004+40 to 1034+10) extends to the east and to the north and is crossed by Interstate 5 at approximate Station 1022+00. In the South Sacramento Streams Study Area GER, the existing levee geometry for the segment is described as follows (URS, 2015c):

• Levee crown width: 12 to 40 feet
• Approximate waterside slope: 2H:1V to 4H:1V
• Approximate landside slope: 2H:1V to 3H:1V
• Approximate levee height: 9 to 19 feet

The GER post-seismic stability analysis for Segment 3 calculates a minimum Factor of Safety (FOS) of

1.29 for the waterside slope and 0.80 for the landside slope. Based on the shape and extent of the landside slope stability failure plane, as well as the varied geometry of the segment, it is possible existing levee material may be used to repair the existing prism if the waterside remains undamaged. However, to be consistent with the procedure outlined in this PERP, the volume of a replacement levee was calculated for this segment.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated using Figure C-S3-3 from the South Sacramento Streams GER Volume 2 (URS, 2015c). This figure is a post-seismic stability analysis cross section at Station 1013+12. The existing levee crown and landside toe were estimated from this cross section to the nearest 0.01 feet using Bluebeam’s scale and measurement tools and were used to calculate the volumes for the full Segment 3.

SEGMENT BLNL-5 (1,919 FEET LONG)
BLNL Segment 5 (Station 1117+55 to 1136+74) extends eastward to approximately 750 feet southwest of Consumnes River Boulevard. In the South Sacramento Streams Study Area GER, the existing levee geometry for the segment is described as follows (URS, 2015c):

• Levee crown width: 15 to 20 feet
• Approximate waterside slope: 2H:1V to 2.5H:1V
• Approximate landside slope: 2H:1V to 2.5H:1V
• Approximate levee height: 15 to 20 feet

The GER post-seismic stability analysis for Segment 5 calculates a minimum Factor of Safety (FOS) of

0.53 for the waterside slope and 0.57 for the landside slope. Due to the shape and extent of the waterside and landside slope stability failure planes, it is expected the full levee prism will require reconstruction.

Levee Crown and Landside Toe Estimates
Levee crown and landside toe elevations were estimated using Figure C-S5-3 from the South Sacramento Streams GER Volume 2 (URS, 2015c). This figure is a post-seismic stability analysis cross section at Station 1129+60. The existing levee crown and landside toe were estimated to the nearest

0.01 feet using Bluebeam’s scale and measurement tools and were used to calculate the volumes for the full Segment 5.

Notes:
1 – American River South Levee, Sacramento River East Levee, and Beach Lake North Levee stationing is based on the system established by URS for ULE.
2 - ULDC Prism assumes crown width = 20 feet and slopes = 3H:1V waterside and landside. 3 - Estimated fill volume to achieve required 10-year levee geometry (ULDC prism with IRDE). 4 - Estimated fill volume to achieve existing top of levee elevation while built to ULDC prism dimensions. .

Assuming the entire levee in a High Vulnerability segment collapses from flow failure and a replacement must be constructed, Table E-2 summarizes the total volume needed for the American River South Levee, Sacramento River East Levee, and Beach Lake North Levee.

E.3.2 SEISMICALLY INDUCED SETTLEMENT
Certain parts of the levee system have been identified as potentially susceptible to seismically induced strength loss. This was determined using estimates of in-situ soil strengths, including residual strengths for layers likely to liquefy, and estimating the levee and foundation soils’ response to anticipated ground shaking from a 200-year-return-period earthquake. Based on this information, the approximate locations and extents of potential seismically induced levee settlement were identified along each segment.

Representative cross sections of the potentially susceptible reaches of the levee system were analyzed for slope failure modes. The remaining freeboard after potential failure was estimated by determining the “ULDC prism” that could fit into the remnant portion of the levee cross-section, assumed to be undamaged. The ULDC prism used in the analyses was a trapezoidal levee cross section with a 20-foot- wide crown at the IRDE and 3H:1V levee slopes. As described in Section E.3.1, settlement from deformation and/or flow failure is anticipated for over 23 total miles of the ARSLS.

The soil quantity for needed interim repairs along a given levee reach (cubic yards) was estimated by calculating the volume of a ULDC levee that meets the required minimum post-earthquake levee dimensions needed to provide a 10-year level of flood protection plus 3 feet of freeboard. Long-term repair quantities assume the levee is being constructed up to the existing top of levee elevation for that interval because they exceed the MTOL for the interval.

Because of the variability of soil properties within the levee system, it is unlikely that all the levee intervals would experience severe deformation to the same degree, or that a damaged section would “run out,” leaving only the remnant prism. In addition, soil from portions of the damaged levee will likely be usable for the interim levee repairs, unless the material collapses into the river. Therefore, the DRAFT

24001006.001A/SAC24R167155 Page 29 of 34 April 18, 2025 © 2025 Kleinfelder www.kleinfelder.com
estimated levee repair fill volumes in Table A3-1 are intended to provide conservative estimates for the reaches that are considered potentially susceptible to damage during seismic shaking. Fill volume actually used would be determined based on post-earthquake inspections and subsequent engineering analyses as appropriate. Needed fill from borrow sites would depend on the ability to reuse existing levee materials. It is anticipated that the primary interim-repair levee fill could come from reuse of existing levee materials.

E.3.3 CUTOFF WALL DAMAGES
Seepage cutoff walls previously installed at each levee segment are susceptible to damage resulting from seismic loading effects. The seepage cutoff walls in the ARSLS are typically two to three feet wide and are covered by a clay cap of thickness two to four feet. Flow failure and deformation are expected to impact the upper portions of the seepage cutoff walls. As part of post-seismic event damage reconnaissance, the seepage cutoff walls should be evaluated by the District Engineer or their designee to assess the need, extent, and types of seepage cutoff wall repair.

Reconstruction of seepage cutoff walls may be necessary for long-term levee remediation to meet ULDC. Shallow damage less than 5 feet below the levee base can likely be replaced with a key trench for a new levee embankment. The construction procedures include degrading the levee to a working platform elevation, installing the wall to the design tip elevation, and rebuilding the levee crown.

Seepage cutoff wall options include open-trench slurry-based designs such as soil-bentonite (SB) walls and drill-based installations such as deep mix method (DMM) walls.

E.3.4 SEISMICALLY INDUCED CRACKING
Because of the various factors affecting cracking, it is difficult to provide a definitive prediction of crack formation at the ARSLS. Investigation of longitudinal and transverse cracking should be considered a priority during post-earthquake reconnaissance of the ARSLS. Transitions in geometry along the levee may constitute locations with higher likelihood for cracking. Areas featuring manmade structures, including street crossings, bridges, turnouts, ramps, structure abutments, and utilities may have been widened or narrowed. Maps and past construction plans should be reviewed to determine additional points of geometric change.

It is crucial to note that the characteristic cross sections referenced in Section E.3.1 are based on locations considered to have the highest vulnerability, as determined by the procedures described in the 2015 URS GERs. Complete slope stability failure and riverbank collapse may not occur continuously DRAFT

24001006.001A/SAC24R167155 Page 30 of 34 April 18, 2025 © 2025 Kleinfelder www.kleinfelder.com
along the entire length of the segment. However, liquefied layers may still result in longitudinal cracks along the crest due to settlement, and transverse cracks may develop adjacent to failed and non-failed portions of the levee. It is assumed that significant damage would occur at the cross-section stations listed in the description of each segment, but cracking of various lengths and depths may occur at any location due to the factors described in Section 3.7.1 of the PERP main text.

E.3.5 LEVEE REPAIR MATERIALS, BORROW SOURCES, STOCKPILES, AND HAUL ROUTES Locations of potential borrow areas and/or stockpiles that could provide the materials needed for interim repairs have been identified. The priority will be to utilize on-site levee materials to repair the damaged levee sections. Where deformed materials are not able to be reused, then borrow materials referenced in Section 3.4 will be transported to the site and used for interim repairs. For immediate response situations, American River Flood Control District (ARFCD) maintains the following stockpiles:

• Limited stockpiles of aggregate base (AB) for roadway repair (10 cy), sand for sandbags (10 cy), and clay soil for levee structure repairs (100 cy) at the RD maintenance yard. • Clay soil stockpile (100 cy) by Unit 8 for levee structure repairs. • Cobble stockpile (40 cy, up to 8-in size) for slope protection by Pump Station 3 (Unit 9).

SAFCA has also identified additional borrow sources which are listed in Section 3.4 of the PERP main report. Attachment 7, Potential Borrow Sources and Haul Routes, shows locations of potential borrow areas and stockpiles that could provide larger quantities of materials needed for interim and long-term repairs as well as preliminary haul routes to the identified seismic deformation zones. Temporary stockpile locations at Sacramento State University, Railyards, Bahnfleth Park, Garcia Bend Park, and near Freeport Boulevard and Cosumnes River Boulevard are generally centrally located in close proximity to the levee segments and ramp access points which may require rebuilding. The Reclamation Districts and SAFCA have maps of available access ramps to the levee. Additional ramps and access points can be constructed to access the critical repair areas, as needed to expedite repair. After an event, stockpiling, haul routes, and levee access points will need to be evaluated by the District Engineer based on the location and extent of damage, type of haul vehicles, potential damage to roadways, and selected borrow location.

Some, but not all, of the proposed borrow sources have been screened for geotechnical properties and environmental contaminates and are accepted for use as fill material for on-going USACE levee projects.

In addition, most of these are active borrow sites, which means the tested material may be removed.

DRAFT

When the PERP is reviewed as part of the 5-year certification review process, borrow sites should also be reviewed since material availability may change over time. Therefore, additional testing may be necessary. It should be noted that in the case of an emergency other locally available sources may be utilized to provide borrow material to restore or repair damaged levee segments. This emergency fill may be utilized without prior testing in order to reduce additional flooding risk. Final levee reconstruction will need to be completed using tested and approved borrow materials and will likely require the temporary repair site to be over-excavated.

E.3.6 EMERGENCY PREPARATIONS AND RESPONSE PROVISIONS
The Levee Maintaining Agency (LMA) for the American River South Levee is the American River Flood Control District (ARFCD). The LMAs for the Sacramento River East Levee south of the confluence is the ARFCD from Station 1000+00 to 1020+00, the City of Sacramento from Station 1020+00 to 1215+00, and Maintenance Area 9 (MA9) from Station 1215+00 to 1770+00. The City of Sacramento is also the LMA for Beach Lake North Levee.

Each LMA has a Flood Safety Plan (FSP) which outlines plans and procedures to address flooding induced by an earthquake. Refer to PERP Sections 4 through 7 for general emergency response provisions and levee repair guidelines.
