SUMMARY
The City Council shall consider the submittal of an application to the Supplemental Benefits Fund (SBF) Committee for the contracting of environmental services and permitting for design and construction activities within the lagoon and riparian areas.

DISCUSSION
The SBF was established under the 2006 settlement agreement related to the Federal Energy Regulatory Commission (FERC) relicensing of Project No. 2100 (Oroville Dam). Up to $61.27 million will be provided by the California Department of Water Resources (DWR) and State Water Contractors over a fifty (50) year license, to be allocated out for appropriate projects, determined by the SBF Committee in accordance to the settlement agreement. Its purpose is to support local recreation and economic development projects, particularly those outside the direct purview of the federal FERC mandated recreational planning.

Since the license has not yet been signed, DWR has agreed to front funding of $200,000/year for projects until the FERC License is approved.

The Feather River Conceptual Plan (FRCP) identifies six (6) areas of reach for project locations and the NOFA includes two (2) additional categories as follows:
 Diversion Pool Area
 Fish Barrier Area
 Historic Downtown District
 Riverbend Park Area
 Oroville Wildlife Area
 Thermalito Forebay
 Marketing/Community Benefit
 Oroville Area Chamber of Commerce
The current Notice of Funding Availability (NOFA) was released on August 24, 2026, in the amount of $450,000, with proposals due by October 8, 2026.
21 Item 2.

The Oroville Public Works Department is requesting approval to apply for the funding of an environmental support contract to supplement the current design effort of Bedrock Park up to $33,000.

The contract will address CEQA development, project design, and construction permitting for the environmentally challenging lagoon and adjacent riparian areas.

1 Summary, Levee Risk Management
Recommendations, and Cost Estimate
The following is prepared for the levee owner/operator by the US Army Corps of Engineers as part of the National Levee Safety Program Levee Review activities (33 USC 46).

Purpose:

This Summary presents results of the Levee Review, including narratives that will be provided in the National Levee Database and accessible to the general public. It also presents risk screening technical results together with supporting figures showing the plan and profile of the levee with key findings.

Levee Summary:

The Levee Summary is public information on the NLD webpage for this levee, providing a general description of the levee.

The Oroville CA Levee 1 was originally built by local interests in 1907. The most significant modifications were made in the 1930s, when leftover earthen spoil materials from gold mining operations (dredge tailings) were placed along the riverside of the levee, widening it to over 250 feet in some areas of downtown Oroville.

The completion of upstream Oroville Dam in 1968 has greatly reduced the frequency and severity of flooding on the levee by regulating flows in the Feather River. Oroville Dam is a multipurpose facility, providing both water conservation and flood risk reduction benefits to downstream communities, including Oroville. Prior to operation of the Dam, the 1955 flood event is estimated to have loaded the levee to 90% of the levee height. Since operation of the dam in 1968, there have been three major floods where the river levels rose high enough to load the levee. During previous floods, the river levels did not reach the top of the levee; however, in an extreme flood event, such as one involving extra water released from the dam during an emergency at Oroville Dam, water could flow over the levee.

Highway 70 behaves as a levee and makes up part of the levee system. Highway 70 is taller and sits at a higher elevation than the levee, but during significant flood events, floodwaters could reach Highway 70 and openings at bridge crossings (Montgomery Street and Oroville Dam Blvd E) would need to be manually closed with temporary barriers, such as sandbags. A drainage pipe near Georgia Pacific Way could also let floodwaters into areas behind the levee and would need to be manually closed with sandbags.
32 Item 3.

Oroville CA Levee 1, Oroville, Butte County, California 10/27/2025 NLD System ID 1905041233
2 Performance and Condition:

The Performance and Condition narrative is public information on the NLD webpage for this levee and describes the expected performance of the levee and potential impacts if it were to breach or overtop.

The completion of upstream Oroville Dam in 1968 has greatly reduced the frequency and severity of flooding on the levee by regulating flows in the Feather River. Since 1968, there have been three major floods where the river levels rose high enough to load the levee. During previous floods, the river levels did not reach the top of the levee; however, in an extreme flood event, such as one involving extra water released from the dam during an emergency at Oroville Dam, water could flow over the levee.

The materials used to construct the levee may allow some water to pass through the levee. There are sections of the levee where slopes are steeper, and the top width is narrow. These sections are more likely to experience water seeping through or risk of the sides collapsing. During one flood in 1997, waterways observed seeping through a narrow section of the levee at Bedrock Park. The seepage was successfully managed by a trained flood fighting team. In addition, the presence of an approximately 3-foot-tall wall at the base on the land side of the levee near Bedrock Park could create a weak point that makes levee failure more likely. If flooding were to reach the top of the levee, the water seeping through and slope stability concerns could be more severe.

To help protect the community, the City of Oroville and the Sutter Butte Flood Control Agency are working to raise public awareness about the risks of flooding and to develop evacuation and emergency action plans. There are also studies planned to better understand levee condition and to identify improvement measures. Some known concerns include water seepage, narrow sections with steep side slopes, weak spots due to the dredge tailings used into construct the levee, and structures, including drainage pipes and a retaining wall, that have been built into or through the levee. 33 Item 3.

3 Levee Screening Risk Assessment Results:

The risk assessment results include a levee risk characterization, along with the recommended LSAC. This information is presented in the LST output and is only available to the levee owner and NLD users with the “regulator/manager of multiple levees” access permissions. 34 Item 3.

Oroville CA Levee 1, Oroville, Butte County, California 10/27/2025 NLD System ID 1905041233
4 • The estimated annualized life loss (EALL) is within societal guidelines (~6E-04). • Low life safety risk primarily influenced by long warning times, historic and expected future high evacuation rates.
• Elevated likelihood of levee failure is mitigated by infrequent levee loading and low life loss estimates.

The levee, constructed in 1907 and modified in the 1930’s using dredge tailings and unknown construction methods, reduces flood risk from the Feather River. As-built drawings are not available to document the design and construction. Subsurface soil data is limited. The structure is currently in fair structural condition, but a critical narrow section with current and historic issues was identified near Bedrock Park.

There is an opportunity for the City of Oroville to expand and document O&M procedures. The levee includes a 3.5 mile section of Hwy 70 that can be loaded. Within the highway reach there are two underpasses that can be loaded by approximately 3 feet of water and requires the installation of two closures using temporary floodfight materials. There is currently no detailed plan to enact these closures.

Significant loadings on the levee are infrequent due to the presence of Oroville Dam about 5 miles upstream. Oroville dam typically regulates Feather River flows below 150,000 cfs, however peak flows approaching 327,000 cfs are possible and would overtop the levee. Estimated annual loading probabilities for most frequently loaded location are as follows:
• Loading at the embankment toe: 1 in 10
• 50% loading: 1 in 150
• Overtopping:1 in 200. The most likely overtopping point is at Bedrock Park (STA 50+00) The flood of record occurred in 1955 before Oroville Dam was constructed (AEP ~6E-03), but no documentation of performance or loading could be found. The 1997 event (AEP ~9E-03) loaded the levee to approximately 33% of its height and resulted in documented seepage through the embankment near Bedrock Park (STA 44+00) and was addressed using sandbag rings.

The estimated annual probability of breach (APF ~5.5E-03) has relatively equivalent contribution from several different potential failures:
• Internal Erosion Through the Embankment. A physical process that was documented to have occurred during the 1997 high water event at Bedrock Park (STA 44+00) • Levee overtopping with Breach
• Embankment Erosion
• Embankment Slope Instability related a brick retaining wall located on the landside of the levee near Bedrock Park (STA 50+00)
If a breach were to occur prior to overtopping, expected life loss is low, but non-zero. In such scenarios, flooding would cover the majority of the leveed area, with water depths ranging from 2 to 14 feet in most locations. If loading exceeds the crest, inundation extents and depth would be similar, but average life loss would be lower.

Total flood risk is primarily driven by levee breach risk, as background (non-breach) risk is approximately a half order of magnitude lower. Non-breach consequences remain low (mean estimate: 0), even when water levels exceed the levee by 3 feet.

Chapter 1: Levee Background Information
Levee System Overview
National Levee Database Levee System Overview: The Oroville CA Levee 1 was originally built by local interests in 1907. The most significant modifications were made in the 1930s, when leftover earthen spoil materials from gold mining operations (dredge tailings) were placed along the riverside of the levee, widening it to over 250 feet in some areas of downtown Oroville. The completion of upstream Oroville Dam in 1968 has greatly reduced the frequency and severity of flooding on the levee by regulating flows in the Feather River. Oroville Dam is a multipurpose facility, providing both water conservation and flood risk reduction benefits to downstream communities, including Oroville. Prior to operation of the Dam, the 1955 flood event is estimated to have loaded the levee to 90% of the levee height. Since operation of the dam in 1968, there have been three major floods where the river levels rose high enough to load the levee. During previous floods, the river levels did not reach the top of the levee; however, in an extreme flood event, such as one involving extra water released from the dam during an emergency at Oroville Dam, water could flow over the levee. Highway 70 behaves as a levee and makes up part of the levee system. Highway 70 is taller and sits at a higher elevation than the levee, but during significant flood events, floodwaters could reach Highway 70 and openings at bridge crossings (Montgomery Street and Oroville Dam Blvd E) would need to be manually closed with temporary barriers, such as sandbags. A drainage pipe near Georgia Pacific Way could also let floodwaters into areas behind the levee and would need to be manually closed with sandbags.

A levee system may include one or more discrete segments representing portions of a levee operated and maintained by a single entity. The segmentation of this levee system is shown in Table 1.1 below.

This report provides risk assessment information on the segment in bold.

Segment Levee Features & Basic Information: The Oroville CA Levee 1 is owned by the City of Oroville.

The National Levee Database has the following information about the levee features that comprise the levee segment and some basic levee geometry (Table 1.2).

Table 1.2: NLD Levee Segment Information

This levee system contains closure structures. A closure structure is a temporary component of the levee system that is put in place at openings along the embankment/floodwall to provide flood protection when the flood source is elevated. Closure structures have many forms, functions, and scales. The following closures were evaluated during the screening risk assessment:

Table 1.3: Closures
Closure Name Closure Type
Montgomery Street Closure Structure Sandbag
Primary Embankment and Foundation Material and Construction Method:

The City of Oroville is located in the northeastern portion of the Sacramento Valley, underlain by accumulated deposits of sands, gravels, and silts eroded from the adjacent mountains. The city is mapped as being underlain by dredge tailings from the adjacent Oroville Gold Fields dredging field.

The original levee was constructed as an earthen embankment with a 4-inch thick concrete facing.

Subsequently dredge tailings were placed along the levee east of Bedrock Park. A Geotechnical Evaluation conducted in 2012 included 14 soil borings; 8 along the levee crown and 6 along the landside levee toe along with laboratory testing of representative samples. Exploration and testing results indicate the levee consists of sands, gravels, and cobbles dredged from the Feather River. Laboratory testing resulted in fines content ranging from 21% to 92% within the levee embankment fill. Most of the samples show moderate to high fines content (>60%), particularly those classified as CL or ML. Sandy gravels and gravelly sands are expected to extend more than 20 feet below the bottom of levee transitioning to native underlying clays, silts, and silty sands.

Additional Screening Comments:

The levee screening was performed on May 8, 2025 by USACE and its contractors for the Inventory and Review effort as authorized by Congress (33 U.S.C. Chapter 46) for the purpose of a one-time review of all levees identified in the National Levee Database. The levee owner/operator (City of Oroville) and the State (CA DWR) participated in the risk assessment. Weather conditions were mild, with no wind and sunny conditions. In addition to the participants listed herein, the following persons participated in the screening:
- USACE - Michael Gonia
- City of Oroville – David Pittman (Mayor), Alyssa Stutz, Brian Ring - CA DWR - Mike Mierzwa, Wade Wylie, David Gordon, Laurence Sanati - Sutter Butte Flood Control Agency- Michael Bessette

- HDR – Daniel M Jabbour
Highway 70 Segment Evaluation:

The assessment team determined that the Highway 70 embankment is not a critical section for levee performance, primarily due to its robust cross-section, which features a wide crest (approximately 100 feet minimum) and flatter slopes (at least 2H:1V). These characteristics increase resilience to internal erosion, slope instability, and erosion-related performance issues. The embankment is constructed with engineered, compacted fill and a prepared foundation in accordance with Caltrans specifications.

The performance section of this report details the rationale for selecting critical levee sections for each assessed potential failure mode. In its current condition, the northern levee reach was identified as more susceptible to performance issues than the highway segment.

Additionally, the highway section is not expected to be a dominant contributor to levee risk. The embankment is less frequently loaded as the Feather River widens downstream, and several feet of freeboard are expected to remain on Highway 70 when the levee system begins to overtop the northern reach. The consequences of a breach along the highway segment would also be less severe, as such breaches are not expected to cause as much inundation to the higher-density downtown Oroville area.

While not identified as a risk driver for levee risk, local participants in the risk assessment described heavy seepage (clear) and resulting flooding behind the levee during the 1997 high water event.

Chapter 2: Flood Hazards
One component of the risk equation is hazard. The risk assessment provides an opportunity to improve the understanding of the sources of flooding and how likely they are to occur. A screening risk assessment will consider all riverine and/or coastal storm surge hazards and use best available information to characterize those hazards. The levee specific hazard and flood loading assessment information is summarized in this section.

The hydrologic and hydraulic data sources and methods used to determine flood hazard data for this screening are listed below:

R&F Engineering (R&F) created a 2D HEC-RAS model of the Feather River (and including the levee) in 2024 for City of Oroville and Sutter Butte Flood Control Agency. The assessment used this model to develop a rating curve (flow vs. loading height) for the levee. For additional information, refer to the Hydrologic Hazard Memo included in the Screening Supporting Information under the LST Documents tab.

The hydrologic and hydraulic data sources were used to develop a loading function for the levee segment which conveys the likelihood of the levee being loaded to a specific percentage of its height. This is a key parameter in the risk computation. One or more flood loading curves may be developed during the screening process to assist in the understanding of hazard. The hazard curve for the levee control location (LCL) - a term used to define the location the levee will overtop first is presented in Table 2.2 and graphically in Figure 2.1 Flood loading probabilities are expressed as annual exceedance probability (AEP) values for physical positions on the levee (toe, crest, and 3-feet above the levee crest). Toe loading represents when the levee structure first encounters flood water. Incipient overtopping represents flood water just beginning to exceed the levee crest elevation.

Chapter 3: Consequences
Consequences refer to the impacts to the area behind the levee in the event the levee breaks or fails or that water flows over it. Consequences can include loss of life, economic losses, and adverse environmental impacts.

The Levee Screening Tool consequence estimate includes loss of life and direct economic damages to property (structures and contents) caused by a breach or water flowing over the top of the levee. The estimate considers both who and what are in harm’s way (exposure) as well as how susceptible to harm they are (vulnerability). Estimates of flood inundation and potential consequences are made in the LST using simplified applications of HEC-RAS and LifeSim.

USACE seeks to manage flood risk to people, property, and the environment, but considers risk to life safety a priority. Potential consequences to environmental, cultural, historic, and important non-monetary resources are qualitatively considered as part of the risk assessment.

Consequence estimates for loss of life and property damage are based on information from the National Levee Database (NLD), the United States Geological Survey National Elevation Dataset, and the National Structure Inventory (NSI) database. Adjustments, except for critical infrastructure, can be made in the LST if there is more detailed consequence information available (e.g. more detailed elevation model).

Basic information about the population and property within the leveed area is listed in Table 3.1.

Emergency Preparedness
Emergency preparedness, along with community and flooding characteristics, impacts the ability and success rate of a population within the leveed area to implement protective action, such as evacuation, during a flood emergency. The following qualitative assessment of evacuation planning, community awareness, flood warning effectiveness, and hazard advanced notice is used to define numeric parameters in the consequence estimating LifeSim model.

Flood
Specific
The City of Oroville provides information on evacuation terminology, routes, and flood evacuation zones in South Butte County through its website, including an interactive evacuation map. While evacuation guidance addresses multiple hazards, the primary focus is on fire and flood events. Butte County maintains a FEMA-approved Local Hazard Mitigation Plan (LHMP), updated under the Disaster Mitigation Act of 2000, which assesses risks from natural hazards and outlines mitigation strategies. Annex D of the LHMP includes hazard-specific evacuation information for the City of Oroville. The County’s Emergency Operations Plan (EOP), updated in April 2022, defines emergency response roles and procedures for large-scale disasters, including floods. Sub-regional evacuation plans, including those for Oroville, feature maps, routes, public assembly points, and preparation tips. The southern and western parts of the county include 11 designated flood evacuation zones. Historically, the city of Oroville was partially evacuated during the 1997 flood event when intense storms threatened levee stability and caused significant regional flooding. This event prompted improvements in emergency planning and flood preparedness for the area. The California Department of Water Resources also maintains updated inundation maps for Oroville Dam to support flood response planning. In summary, Oroville and Butte County have developed multi-hazard evacuation plans, with floodspecific components, historical experience responding to flood threats.

Community
Awareness
Very
Aware
Community members are aware that they could be impacted by a flood event and their lives could be at risk if they do not evacuate. The City of Oroville is located almost immediately downstream of the Oroville Dam. In February 2017, heavy rainfall damaged the main and emergency spillways at the Oroville Dam and prompted the evacuation of approximately 200,000 people downstream of the dam, which included those located within the City of Oroville. The Oroville Dam Spillway Incident was heavily covered in the media and still is a topic of discussion today. Overall, it is estimated that the community has a high perception of flood risk.

Flood
Warning
Effectiveness
Fast Appendix H of Butte County’s Emergency Operations Plan (EOP) addresses flooding and dam failure emergencies. Section 4 details agency roles in flood response and warning dissemination. Appendix H emphasizes the importance of robust public warning systems, which include electronic alerts, news broadcasts, Code Red (an opt-in multilingual alert system), and door-to-door notifications. Key alert systems used to notify the public, that were also used during the 2017 Oroville Dam Incident, include: emergency radio (1460 AM), landline and cell phone notifications; social media; television; reverse 911, FEMA’s Integrated Public Alert & Warning System (IPAWS), and Alert FM. These systems support rapid dissemination of evacuation orders. According to the 2018 ASDSO Conference Paper by Gregory Richards, Jason Needham, and Jesse Pope titled, "The Human Element: Warning and Evacuation During the Oroville Dam Incident," most respondents of their research surveys indicated most people sought additional information before taking action to evacuate. Taking this into account, the research paper developed PAI curves for two different populations (Butte County and Sutter/Yuba Counties further downstream). These curves show the downstream communities took protective action at quicker rates than the curve in LST, even with High Risk Perception and Fast Flood Warning Effectiveness ratings. Population 1 (Butte County) curve showed 90% of people took action about 100 minutes after warning issuance and Population 2 (Sutter/Yuba Counties) curve showed 90% of people took action at about 240 minutes.

flood patrol and response activities is expected, the City does not have well documented flood response plan that would support efficient detection and locals lack experience to determine when conditions require mandatory evacuation notice initiation. Historically, in 1997, evacuation notice was sent initiated primarily by the high-water flows and not directly related to the levee distress (seepage at Bedrock Park). Short is conservatively selected based on the lack of a well-documented plan and limited local knowledge, training, and experience with flood response.

Long The Butte County EOP outlines varying activation levels for emergency response which include monitoring flood watches, major incidents or potential incidents, and severe weather. Based on the County's level of preparedness when monitoring and responding to flood hazards and given that historic events hazard allowed adequate warning time, it is estimated that the amount of warning time available for an overtopping scenario would be approximately 8 to 24 hours (long). California Department of Water Resources also monitors atmospheric river forecasts days in advance and actively monitors water levels behind Oroville Dam during major storm events.

Inundation & Consequence Modeling
Inundation modeling is completed with HEC-RAS hydraulic modeling software. Each inundation set has three inundation scenarios. For breach prior to overtopping, the scenarios are 50, 75, and 100-percent load. For overtopping, the scenarios are 1, 2, and 3-feet above the 100-percent top-of-levee load with and without breach. The expected inundation depths of Breach Prior to Overtopping at 100% loading is viewable in Figure 3.1. The inundation extending into the flood source indicates the approximate location of the modeled breach.

The LifeSim software is used to simulate the movement of people during a flood evacuation in order to better understand the potential for life loss and flood-induced property damages.

Consequences Results
Consequences Narrative: Incremental life loss is expected to be very low across all scenarios with an estimated mean life loss of zero, with scenario-dependent ranges between 0 and 8 fatalities. In a breach prior to overtopping scenario where a potential breach occurring near the City of Oroville popoluation center, a breach would occur relatively quickly with the erodible embankment materials. Breach flows would be on the residential community directly adjacent to the levee and generally travel south and flow through the leveed area taking several hours. (The breach prior to overtopping scenario of the Montgomery St closure would result in breach flows on the order of hundreds of cfs and inundate a much smaller extent, dramatically reducing the exposed population at risk). Despite the life-threatening flood depths, the anticipated life loss is very low due to the strong evaucation planning, flood warning effectiveness, and high community awareness of flood risks the exposed population as percentage of the population at risk is low. As demonstrated by historical events the community's capacity for large-scale evacuation is strong. In 1997, the City of Oroville issued an evacuation order roughly two hours after identifying a flood hazard, successfully evacuating about 10,000 people within seven hours. During the 2017 Oroville Dam spillway crisis, approximately 200,000 downstream residents, including Oroville, were evacuated.

In an overtopping breach scenario, expected breach flows are expected to be about half as much (~5,000cfs) as the breach prior to overtopping scenario due to the shorter levee height at the incipient overtopping location. The inundation extents are relatively similar between scenarios, with the primary difference being the advanced hard notice offered by Oroville Dam high flow release warnings to the affected downstream communities. Although formal evacuation triggers are not currently in place, the City maintains a direct communication line with Oroville Dam operators, enhancing situational awareness and enabling coordination of controlled spillway releases. As a results, the exposed population at risk is even lower than in a breach prior to overtopping scenario and very low life loss is expected.

It should be noted that the LifeSim modeling inside the LST does not account for potential life loss on roads. There was significant traffic congestion noted during the 2017 Incident. Eyewitness accounts describe frustrated and anxious evacuees stuck in bumper-to-bumper traffic for hours, according to local news (KRON4). There is potential for some life loss to occur during traffic congestion from a mass evacuation.

Economic damages are projected at approximately $110 million (representing the probability weighted average damage for all levee breach inundation scenarios), and critical infrastructure may be affected by inundation or levee breach including several schools, an urgent care center, and key utilities.

Overtopping with Breach 0.05 0% $175M 646
The simplified application of LifeSim in the levee screening tool does not account for potential loss of life on roads. In the simplified methodology, if people leave their structure prior to the flood arriving, they are assumed to be safe. However, the difference in time between when people leave their structure and when water arrives at their structure can provide insights as to whether loss of life on roads is likely to be high.

For this assessment, 1% of the evacuating groups left their structure within 30 minutes of water showing up at their structure. Anything over 10% could lead to significant increase in estimated loss of life if a full evacuation study is completed depending on road network congestion and distance to safety.

Critical Infrastructure Comment: The critical infrastructure is typically defined by structures within the leveed area based on information from the Homeland Infrastructure Foundation-Level Data (HIFLD) Open database. However, for this leveed area, no critical infrastructure features were identified by HIFLD. The following critical infrastructure were identified during the on-site activities and provided by city staff during the risk assessment workshop:

Chapter 4: Levee Performance Assessment
Flood Performance History
The levee has not experienced a failure breach from any performance mode prior to overtopping.

Based on past performance, the City has flood fought in the past; during the 1997 event sandbagging was performed to fight the seepage that occurred near Bedrock Park. Note that while some sources describe a sand boil, anecdotal first-hand observations shared during the workshop indicated it was heavy seepage flow near the toe and not a typical boil emerging from the foundation.

The levee has not overtopped.

There is no documented record of any floodfighting intervention to prevent levee overtopping.

Performance Assessment
Levee performance assessment in the levee screening tool is accomplished by evaluating the likelihood of specific levee failure modes. A failure mode is a unique set of conditions and/or sequence of events that could result in failure. The levee was evaluated for expected flood performance with water loading to the levee crest for the following potential failure modes:

Each potential failure mode is expanded into an event tree that describes the physical process of initiation to breach. Each node of the event tree (typically being: initiation, continuation, progression, unsuccessful intervention, and breach) has a rating of likely, neutral, unlikely or very unlikely. The values associated with those qualitative descriptors are 0.9, 0.5, 0.1 and 0.01, respectively. The elicitation considers flood loading at the levee crest except for the overtopping breach PFM which assumes 1 foot of overtopping. Each node is independent of the previous node. The risk assessment team uses available design, construction, condition, and past performance information about the levee to inform their ratings of each node. The likelihood of the potential failure mode completing the failure process is equal to all the nodes multiplied together. Reference the LST 2.0 Technical Manual for additional details on the screening risk assessment methodology and guidance.

Backward Erosion and Piping in Foundation
Failure Mode Description: In general, backward erosion piping occurs when soil erosion (particle detachment) begins at a seepage exit point - caused by excessive uplift pressure - and erodes backwards (upstream), supporting a “roof” along the way. As the erosion continues, the seepage path gets shorter, and flow concentrates, leading to higher gradients, more flow, and the potential for erosion continues to increase. More simply, this failure mode is the result of seepage weakening the ground supporting the levee.

The potential failure mode event tree was evaluated with the following node qualitative and/or numeric values displayed in Table 4.1 below:

Table 4.1: Node Ratings
Node Rating Value Justification
Initiation Neutral 0.5 The likelihood of initiation at this location is assessed as neutral, based on competing factors that would suggest both increased and decreased likelihood of BEP.

Sandy Soils at Toe: Relatively clean, fine sands were observed at the toe of the slope below the levee section adjacent to Bedrock Park. Local knowledge also indicated the area of Bedrock Park historically functioned as a natural beach, consistent with the presence of native sandy materials. Based on the anecdotal information, fine to medium sands are possible with continuity from waterside to landside, however, this was not apparent within the foundation soils from the available exploration logs.

Absence of Observed Foundation Boils or Erosion: There is no documented evidence of foundation boils or eroded material deposition at this site, which are key indicators of BEP. The absence of these signs suggests that seepage noted during past flood events did not result in progressive erosion or instability.

Lack of Preferential Flow Features: A review of geologic and historic topographic mapping does not indicate any geologic, geomorphologic, or terrain features that would promote preferential or concentrated seepage paths, such as buried channels or paleosols.

Foundation Soil Composition: Backwards erosion piping requires a continuous layer of fine to medium poorly graded sands in the foundation. The subsurface explorations (borings) did not encounter this condition. Based on the available boring logs, the foundation materials in this area are generally described as dense sands and gravels with cobbles, interbedded with silt and clay. The relative density and particle size distribution for this material is not conducive to piping erosion. The presence of cobbles further enhances resistance to piping by disrupting potential continuous flow paths and increasing the energy required for particle movement. These soil characteristics reduce the likelihood of underseepage initiation through the foundation.

Continuation Likely 0.9 An unfiltered exist likely exists at landside toe. The levee has no engineered filter or toe drain.

Progression Neutral 0.5 The likelihood of progression at this location is assessed as neutral, based on competing factors that would suggest both increased and decreased likelihood of progression. Duration is likely sufficient to progress a piping failure, but the foundation material is not expected to hold a roof. Relatively long duration of flow (~4 days) is possible based on anecdotal observations during flood events in 1997 and 2017.1997 event had a large snowpack melt whereas 2017 event was mostly rain. Foundation soils generally expected to be granular soils and non-plastic silts which are not likely to hold a roof for progressive erosion. However, deeper foundation soils may include fine-grained soils with potential to hold a roof.

The City has experience with flood response, having taken action during past events such as the 1997 flood, when sandbagging was used to address seepage near Bedrock Park. The City is capable of Unsuccessful

Internal Erosion through Embankment
Failure Mode Description: The internal erosion failure mode consists of multiple sub-categories of ways levee soil can be eroded by the mechanism of water flow within the levee. Two of the main ones are concentrated leak erosion and internal migration. The driving physical process for internal erosion assessed for this screening is Concentrated Leak Erosion.

Station 44+00 was selected as the critical section for evaluation of Internal Erosion (Bedrock Park) due to levee geometry, potential continuous flaw, uncertainty in the levee embankment fill material, and past performance with heavy seepage noted during previous flood events without mitigative or remedial repairs. This portion of the levee is relatively narrow with steep slopes and located at a transition from the original 1907 concrete-faced levee section to the widened section, overbuilt dredge tailings. A nearby boring identifies the levee fill as a silty sand (although rotary drilling method into a coarse soil may have returned a not representative sample). At this location, the random fill may include a continuous highly porous zone initiating soil contact erosion of the silty material. The concrete faced historic levee terminating immediately downstream of this location may introduce flow concentration to the area.

Highway 70 embankment was determined not to be a critical section (see Levee Information tab for more detail).

Table 4.2: Node Ratings
Node Rating Value Justification
Initiation Likely 0.9 Initiation rated likely due to evidence of past seepage that has not been repaired. Heavy seepage was documented (photo and video) near this location during 1997 flood event (~47% loading) and anecdotal discussion of similar occurrence in 1986. While some of the provided information describes a sand boil at this location, further review of documentation and discussion with those that observed the event suggests that this was seepage through the embankment emerging near the landside toe and not a typical boil.

Additionally, during the on-site levee inspection, animal burrows were observed on the landside slope/toe and trees were observed on both the landside and waterside slope.

Continuation Likely 0.9 An unfiltered exit likely exists at landside toe. The levee has no engineered filter or toe drain.

Progression Neutral 0.5 The levee is primarily composed of granular soils and non-plastic fines—such as cobble, gravel, sand, and silt—which are generally not conducive to forming a stable roof. However, soil classifications from borings at this cross-section include SM (silty sand), suggest potential for soils to have sufficient cohesion to support a roof structure. There is also uncertainty regarding the location and condition of the original 1907 concrete-surfaced levee section.

Where this buried concrete facing is damaged or only intermittently present, it may concentrate seepage flows or promote the formation of voids, as has been observed in upstream areas where the concrete has been exposed. At this location, the levee crest is about 38-feet wide and 14-feet tall with a landside slope of about

2.5H:1V.

Regarding flood duration, relatively long periods of elevated water levels—on the order of 4 days—are possible near the toe or just above it during rain-on-snow events, as previously noted. Durations above 50% of the levee height (corresponding to approximately 180,000 cfs at station 44+00) are more difficult to quantify due to the lack of historical events of this magnitude following the construction of Oroville Dam, but could range from 1 to 2 days.

Durations at or above 100% levee height are expected to be less than 1 day.

Unsuccessful
Intervention
Neutral 0.5 Based on past performance, the City has flood fought in the past; during the 1997 event sandbagging was performed to fight the seepage that occurred near Bedrock Park. The City has the ability to contact other entities to help with flood fighting response.

Forecasting abilities are generally very good. More advanced flood fighting techniques may be needed. City has levee patrols which makes identification likely. Nearby borrow sources are available for material.

Failure Mode Description: Stability potential failure modes occur from lowering the levee crest due to shear failure of the levee embankment and foundation or instability of the levee slopes leading to overtopping, erosion, and breach.

Table 4.3: Node Ratings
Node Rating Value Justification
Initiation Neutral 0.5 The likelihood of initiation at this location is assessed as neutral, based on competing factors that would suggest both increased and decreased likelihood of initiation.

HDR’s 2015 steady-state slope stability analysis for the Bedrock Park area indicated a factor of safety (FS) of approximately 1.0 or less under extreme flood conditions at the top of the levee, suggesting potential for slope instability. The analysis assumed a relatively shallow failure surface and adopted conservative effective shear strength values of 35 to 36 degrees. These values were lower than the 43 to 47 degrees that HDR estimated from correlations with the equivalent blow count and Plasticity Index, indicating a conservative approach. The landside slope in this area is inclined at approximately 1.5H:1V and consists of embankment fill classified as SM (silty sand). Importantly, the section containing the existing brick retaining wall was not included in HDR’s analysis.

The top of the landside retaining wall is at approximately the levee crown.

Observations shared during the workshop, including a report from a DWR attendee, noted outward rotation of the wall —though the magnitude was unspecified— as well as lack of wall drainage (i.e. weep holes) raising concerns about its structural adequacy and potential contribution to localized instability.

It is also worth noting that, despite the low FS values under extreme conditions, there have been no documented slope stability issues in this area based on past performance.

Continuation Likely 0.9 Continuation is likely as the levee is a relatively homogeneous embankment and there is no continuous higher strength core (zone) or cutoff within the levee to intercept slope failure surface.

The location of the Concrete on the waterside slope surface is not expected to significantly contribute shear strength or resistance of continuation of landside slope instability.

The primary concern centers on a more global failure mechanism initiated by the retaining wall, rather than progressive shallow failures as modeled in HDR’s analysis of nearby section without the retaining wall present. While HDR’s analysis considered shallow slip surfaces with low factors of safety under extreme conditions, these are not expected to retrogress through the full levee section.

Displacement—such as rotation or settlement—or failure of the retaining wall could initiate localized instability, potentially leading to subsidence or partial slope failure. However, such a failure is not expected to result in complete loss of the levee crown.

Flood durations just above the levee toe could be relatively long during certain events, but the granular and gravelly nature of the embankment fill makes it unlikely that retrogressive failures would continue beyond the initial movement. Once displaced, the coarse material is expected to stabilize and resist further movement.

Additionally, there is no documented history of slope instability in this area, which supports the conclusion that while localized deformation may occur, a full breach or crest loss is unlikely under Progression Unlikely 0.1

the anticipated conditions.

Unsuccessful
Intervention
Neutral 0.5 Given the retaining wall's easily accessible and high visibility location, signs of distress or failure—such as movement of the retaining wall or visible slope deformation—are likely to be detected promptly through routine patrols. The presence of the retaining wall, however, introduces a potential failure mode that could occur rapidly, particularly if the wall were to collapse suddenly. In such a case, the opportunity for early detection may be limited, depending on the nature and speed of the failure.

In terms of intervention, access to the site is generally good, and nearby borrow sources for soil and rock are available to support rapid construction of a buttress or other stabilization measures.

While the potential for a quick failure initiated by retaining wall collapse could reduce the total time for effective response, the initial wall failure is not expected to result in global failure of the embankment.

Failure Mode Description: Erosion potential failure modes occur when the loss of the levee is caused by erosion of the levee embankment or foundation from due to wave action on the waterside of the levee, or by high velocity channel flows flowing across the waterside slope or at the toe (scour). The evaluation of this potential failure mode focuses on the erosive force of the hazard source and the levee's ability to resist that with its designed or natural features.

Table 4.4: Node Ratings
Node Rating Value Justification
Initiation Likely 0.9 The levee is constructed of dredge tailings consisting of sand, gravel, silt, and cobbles, which are expected to be highly erodible.

The riverside slope is relatively steep—approximately 2H:1V or steeper—and no engineered erosion protection was observed. HECRAS modeling indicates overbank velocities in this reach of up to 8 feet per second, the highest observed along the waterside slope.

While vegetative cover provides additional channel roughness, the presence of isolated large or dead trees increases vulnerability.

Continuation Neutral 0.5 Levee material is expected to be relatively consistent and comprised of erodible to highly erodible soils. However, as erosion initiates, it may expose cobbles which will be less erodible than the loose density granular surface soils, resisting continuation.

Progression Neutral 0.5 The likelihood of progression at this location is assessed as neutral, based on competing factors that suggest both increased and decreased potential for erosion to advance through the levee. The levee crest is approximately 20 feet wide and 6 feet high, with a landside slope of about 3H:1V. The relatively wide levee section would require a longer duration of hydraulic loading for erosion to progress to breach. On the other hand, NHC’s 2015 Detailed Erosion Evaluation identified the potential for significant erosion into the levee prism due to tree fall-induced scour. However, this estimate was based on individual erosion processes—channel migration, tree fall, and wave action—evaluated separately. The greatest erosion depth was associated with a “pier scour” analogy, using a conservative 2H:1V layback slope assumption. This scenario represents a likely worst-case condition and did not indicate erosion progressing fully through the levee cross-section.

Unsuccessful
Intervention
Likely 0.9 Active erosion occurring below the water surface can be difficult to observe during flood events.

Access for intervention is generally available along the levee crown, with sufficient entry points for equipment and personnel. However, dense vegetation and other encroachments on the riverside slope may hinder rapid deployment of erosion control measures. The slope itself is relatively steep (approximately 2H:1V) and tall—estimated at around 50 feet from the levee crown to the channel bottom—posing logistical challenges for implementing effective erosion mitigation. Furthermore, local experience and planning specific to responding to riverine erosion PFMs is limited, which may reduce the effectiveness or timeliness of emergency response efforts.

0.01 In general, forecasting capabilities are very good, particularly given that flows are primarily influenced by controlled releases from Oroville Dam. Communication between the Dam and City is enhanced by participating in the Oroville Dam. Communication between the Dam and the City is enhanced by frequent direct communication between DWR’s Oroville Field Division staff and City staff, including participation in annual dam safety exercises and maintenance of the Dam’s Emergency Action Plan (EAP) call tree.

Closure Not
Placed in Time
Neutral 0.5 The city does not currently have a documented EAP with triggers established which reduces confidence that closure is placed in time. However, deployment capabilities are available and even without triggers being established it is expected the city would be communicating with DWR about support needed to deploy closure structures. Anticipate closure structure would need to be 3 feet tall and about 75 feet wide for protection to match incipient overtopping location near Bedrock Park. While the City believes this is possible, they would currently be relying on external support from DWR. It is possible that during an extreme event that would require a closure, external resources may be constrained.

Structure
Instability
Unlikely 0.1 While a specific temporary closure has not been identified, a sandbag pyramid was discussed during the workshop as a
potential measure, and it is considered unlikely to fail. The limited height (3-feet) of the closure increase confidence in its stability. In this area, debris impacts on the closure structure are not expected, and floodwater velocities are anticipated to be relatively low. (Note: other mor rapidly deployable and less labor intensive closure types are possible given dimensions.)
Unsuccessful
Intervention
Unlikely 0.1 Detection: The closure structure location is easily accessible and in a high visibility area increasing the likelihood of detection of seepage or distress. Intervention: Buttressing a 3-foot tall closure with additional sandbags was discussed. Unlikely rating supported by CA DWR flood specialist involvement. Given that the closure is placed (assuming DWR installation involvement), CA DWR flood fight specialists will be deployed to assist in monitoring for distress and have materials and experience to perform any needed intervention.

Initiation Likely 0.9 Levee is constructed of dredge tailings, consisting of gravel sand, cobbles, and generally non-plastic fines. Levee soils are considered erodible to highly erodible. The existing landside retaining wall at this location would create turbulent flow conditions.

Continuation Likely 0.9 No erosion resistant barrier within the levee that may resist or arrest erosion.

Progression Likely 0.9 Levee crest is about 6-to-8-feet-wide at this location and is constructed of erodible to highly erodible soils. Duration for extreme events that would cause loading near 100% of levee is expected to be on the order of 6 to 12 hours. Overtopping would be similar order of magnitude, maybe closer to 6 hours.

Neutral 0.5 The incipient overtopping location is known and manageable levee reach of lower levee elevations totaling 300-to-500-feet in length.

Access to this location is available. Flood forecasting would provide adequate time to prepare. Flood fighting could include installation of an erosion resistant emergency spillway. CA DWR, a trained and experienced agency, is likely to be engaged with on-site for technical assistance for a flood event of this magnitude increasing likelihood of successful OT breach intervention. However, some features in the overtopping reach, including the existing retaining wall present complexities to installation that may prohibit timely installation. Also, overtopping would occur during an extreme event and there is a chance that resources may be constrained. No details on triggers or procedures for this flood fight action are documented in an O&M manual or flood response plan.

Chapter 5: Risk Assessment Results
Levee Safety Action Classification
To be determined.

Levee (Incremental) Risk
Levee (incremental) risk relates to the likelihood and consequences of a levee failure. Levee risk incorporates the following three inundation scenarios: prior to overtopping; overtopping with breach; and component malfunction/mis-operation.

The estimated total annual probability of failure (APF) is 5.517E-3 failures per year with flood fighting.

The estimated weighted average incremental life loss is 1.116E-1 lives per failure with flood fighting.

Therefore, the best estimate of the expected annual incremental life loss (EALL) is 6.156E-4 lives per year with flood fighting.

The estimated weighted average incremental economic cost is $111,700,389 per failure. The best estimate of the average expected annual damage (EAD) economic cost is $616,219 per year.

Non-Breach Risk and Flood (Total) Risk
Non-breach risk is realized when floods exceed the capacity of the levee, but the levee does not breach.

The magnitude of non-breach risk indicates the level of risk to a community remaining even if the levee performs as designed. The total incremental (levee) life safety risk and non-breach life safety risk are plotted together to inform the understanding of levee area flood (total) risk and potential overtopping resiliency and efficiency benefits, as shown below. The levee risk portion of the bar is the amount of risk that could be reduced through remediation of the existing levee (without raising it).

NFIP Evaluation
A screening risk assessment is not scoped to make a determination on the levee system’s accreditation status in the National Flood Insurance Program (NFIP). However, USACE and FEMA are committed to sharing levee information and the results of this risk assessment are made available for NFIP purposes.

Major Findings and Understandings
Overall Risk
• This is a low life safety risk levee, with an annual probability of inundation between 1/100 and 1/1000.

Given inundation, low life loss is expected.

Hazard
• The Feather River is regulated by Oroville Dam, about 5 miles upstream. • Since the dam's construction in 1968, peak flows have been reduced. • Floods typically last 1–2 days, with events including snowmelt (e.g., 1997) being longer duration. • Flood loading at the levee toe generally ranges from 0.02 to 0.01 AEP, with localized low-elevation areas (e.g., Sta. 44+00 at 156’ NAVD88) reaching 0.1 AEP. • At 0.005 AEP, overtopping is possible near Bedrock Park (Sta. 44+00 to 56+00). Closure structures may allow water entry at: Montgomery St (Sta. 74+75, 0.007 AEP), Oro Dam Blvd (Sta. 112+50, 0.005 AEP), and Box culverts (Sta. 182+35, 0.007 AEP)
• Uncertainty exists due to reliance on FIS hydrology rather than updated reservoir operations; however, a Water Control Manual (WCM) update is planned.

Performance
• The 1907 concrete-faced levee remains visible at Bedrock Park; some portions may have been removed or buried under dredged materials in the 1930s. • Levee width ranges from 30 to 250+ feet; height varies from 6 to 19 feet. • Primary breach drivers include slope instability, internal erosion, and riverine erosion. • 1997 flood (160,000 cfs, approx. 33% loading) caused seepage near Sta. 44+00, flood fighting Oroville CA Levee 1 California

performed, no breach occurred.
• Vegetative cover adds channel roughness; however, isolated large or dead trees on the waterside increase vulnerability. NHC analysis shows potential tree-fall induced pier-type scour up to 16 feet deep. • A brick retaining wall near STA 50+00 at Bedrock Park (landside) shows signs of instability and rotation, the observed movement indicates potential vulnerability under flood loading. • Although access to the retaining wall area, during potential overtopping, the geometry of the wall could hinder emergency overtopping response measures, potentially limiting effective intervention. • Per 2015 HDR analysis, the levee near STA 44+00 does not meet standard factors of safety for seepage or slope stability. There is some uncertainty about subsurface conditions due to limited past investigations. Anecdotal reports suggest sandy historic beach deposits in the Bedrock Park area. • Stormwater pipes penetrate the levee, but conditions and closure mechanisms are largely unknown. • The City lacks written levee maintenance or inspection plan. • There is no formal flood fight manual, no materials stockpile, and limited trained staff. • No formal closure plan exists for Montgomery Rd, and limited experience leads to inconsistent expectations for response success across failure modes.

Consequences
• The City of Oroville has some flood response experience (e.g., 1997) and is familiar with levee operations.
• Emergency services and the public are generally aware of flood risks, improving the likelihood of effective evacuation. Outreach efforts by the City and Sutter Butte Flood Control Agency are ongoing. • However, the City lacks a formal Emergency Action Plan (EAP) with specific trigger gauges or thresholds.
• Expected average life loss is near zero, but up to 4 fatalities are possible near breach zones under certain scenarios.
• Inundation depths generally range from 0–6 ft, with some localized areas reaching 6–14 ft, particularly near Rotary Park, between Montgomery St and Oro Dam Blvd E, and south of Cal Oak Rd. • Life loss risk is driven primarily by these deeper inundation zones: West of Rotary Park (Sta. 41+00), and Between Mitchell Ave and Oro Dam Blvd E (Sta. 89+00 to 112+00) • Critical infrastructure at risk includes non-redundant utilities, schools, medical facilities, treatment plants, and evacuation routes.
• Future development south of Oro Dam Blvd may increase consequences and underscores the need for enhanced flood safety.

Uncertainty
• The Oroville Dam WCM update may alter future flood expectations. • The extent of the original concrete-faced levee outside Bedrock Park is unclear. • This screening focuses on levee performance; risks from interior drainage and culvert inflow (e.g., near Sta. 180+00) were not evaluated and remain poorly understood. • Given the AEP of the toe of the closure at Montgomery St (Sta. 74+75, 0.007 AEP), the 1955 event (203,000 cfs; 0.006 AEP) loading would indicate the need for installing the closure, but the team doesn’t know if the closure was actually installed though unlikely given there is no formal O&M plan for a closure structure.

Other
• This assessment assessed levee risk and did not quantify the magnitude and impacts of other flooding scenarios including heavy seepage quantities and/or interior drainage issues including ungated outfalls. Soil properties and historical evidence during 1997 high water suggest that seepage and interior drainage issues are possible. According to local participants, the 1997 event caused backwater of interior drainage canals that threatened the wastewater treatment plant ponds (within ~12 inches of the crest).

Levee Review Field Data Collection Purpose
As part of the National Levee Safety Program, USACE has the authority to conduct a one-time review, known as Levee Review, of all levees identified in the National Levee Database to provide a clearer picture of levee-related flood risk nationally and a baseline of levee information. Under this initiative, USACE can facilitate a levee site visit and screening-level risk assessment. This report documents the field data collected during the Levee Review site visit.

Field observations help better understand the general condition of the levee to inform risk screening and the development of order of magnitude cost estimates. This is not considered a detailed inspection. This report contains a list of team members at the field visit, an inspection summary, narrative of observations, photos of levee conditions, and a map including observation locations and highlights of conditions for consideration in the screening risk assessment.

Observation Types
Levee Condition Observations are collected to document the current levee condition including operation and maintenance items needing action and may be found to impact levee performance in the risk assessment.

General Observations are observations documented to characterize the levee and its components to inform understanding of the levee system for the risk assessment.

Generally, these are informational only and do not require any maintenance action. 88 Item 3.

Levee Segment Summary:
[Provide an Executive Summary of the segment inspection considering (1) the general condition of the segment, (2) the rationale for key Item ratings, categorized by Feature , and (3) the quantity or severity of notable observations/deficiencies and (4) notable changes in condition since the last inspection.] USACE and its contractors performed this field data collection as part of the one-time Levee Review program. The primary purpose of this field data collection was to verify levee information contained in the National Levee Database and collect supplemental data to inform the screening level risk assessment. In addition, the field visit included general levee condition assessment, review of O&M and emergency preparedness activities, and data collection in support of the development of recommendations and associated cost estimates for risk reduction measures. Field observations focused on identifying factors and conditions that could affect the levee’s ability to perform as intended under flood loading. As such, the report does not contain a detailed documentation of levee condition and is not intended for use in evaluating operation and maintenance activities.

The field data collection activity included a walking inspection of accessible reaches of the levee alignment within the upstream end of the levee from Station 0+00 to where it ties into the Hwy 70 embankment near Station 65+00. The inspection began at the Hwy 70 tie-in and headed upstream along the levee. The Hwy 70 portion of the levee was not part of the walking inspection, instead an inspection by vehicle was conducted of the Montgomery St underpass to support evaluation of a possible closure at this location during the risk assessment.

Major findings from the inspection are summarized below, with additional details provided in the report:
1) The levee section width varies along the levee length and includes an original concrete-faced section near Bedrock Park and dredge spoil sections exceeding 250 feet in width near downtown Oroville. The condition and presence of the original concrete facing beyond Bedrock Park is unknown, however, the top, backside of the wall was observed at other isolated locations upstream of Bedrock Park.
2) The maintenance condition and surface material varies between pavement, gravel and grass depending on purpose (i.e., park, roadway etc.) of the levee crest. 3) The rock wall on the levee crest near Bedrock Park is not continuous (includes gaps), show some signs of distress/damage, and not considered a structural nor levee/floodwall feature. 4) No major slope instability was noted; however, shallow scarps and displacement were noted between Stations 55+00 and 62+80. Portions of the riverside are steep, measuring up to

1.75H:1V between Stations 26+00 and 45+00.
5) A masonry brick retaining wall was observed on the landside near Bedrock Park. The retaining wall condition did not appear to be maintained, the wall appeared to have slight tilt inward indicating rotation at the foundation, typical design features such as weep drains were not observed. Due to the observed condition, the wall presents a potential stability to the toe of the slope along this section of the levee.
6) Vegetation is dense in some areas of the waterside slope, complicating access to stormwater pipes. 7) Multiple stormwater discharge pipes were observed, with several lacking closure devices and others difficult to access due to vegetation and erosion. 8) Animal burrows of approx. 4 to 24-inches diameters were found on the levee embankment at multiple locations. 9) The Montgomery St Hwy 70 underpass presents a potential closure (approximately 70-feet wide and 3-feet tall), however, the City does not currently have a documented plan for the closure.
10) Seepage was recorded during the 1986 and 1997 flood events at Bedrock Park. No breaches were reported during either event, flood fighting was performed in 1997. No repairs have 90 Item 3.

been made at the location of historical seepage.
11) Several trees were observed on the waterside levee slope, including but not limited to Stations 14+30, 55+30, and 56+00. Observed tree diameters ranged between 12 to 56-inches.

A map containing the observation points within this report is included at the end of this document. Stationing included in this report is consistent with the stationing used in the National Levee Database (NLD) and Levee Screening Tool (LST).

Levee System Summary:

1. Operations and Maintenance Manuals
Description: Verify that Levee Owner's Manual,
O&M Manuals, and/or manufacturer's operating
instructions are present. Describe the age,
comprehensiveness, and applicability to current
conditions.

Summary: The owner, City of Oroville, does not have a written operation and maintenance manual. City of Oroville understands the levee and its vulnerabilities well and has experience of successful flood fighting.

Observation(s):

2. Emergency Supplies and Equipment
Description: Document the availability, condition,
and quantity of emergency supplies and
equipment. Materials should adequately supply all
needs for the initial days of a flood fight.

Document maintained stockpile of sandbags or
other flood fight supplies relevant to specific levee
components.

Summary: The owner, City of Oroville, does not currently have stockpile of emergency supplies for flood fighting. They do have available sources for materials identified.

3. Flood Preparedness and Training
Description: Provide a description of the levee
owner’s documented flood responses plans,
training, and experience. Document the general
level of detail on the flood response plan as levee
system specific or general. Does the levee owner
maintain a list of emergency contact information
for appropriate personnel and other emergency
response agencies. Is it current or out-of-date?
Does the flood response plan use triggers to
implement specific emergency operation
activities? Describe the levee owner’s
understanding of how to operate, maintain, and
staff the levee system during a flood. Does the
levee owner have detailed knowledge or only
general working knowledge? Document any recent
examples of flood response. For levee systems
with closures structures, describe the detail
provided on the closure plan, including
demonstration that sufficient flood warning time
exists for the completed operation of all closure
structures.

Summary: The owner, City of Oroville, does not have a documented flood response plan and limited trained local personnel for flood fighting. They expect support and materials will be available from other agencies (DWR) to support flood fighting needs. They do have general working knowledge and experience with flood fighting during the1997 flood event. At that time emergency responders mobilized to fill and place sand bags at the location of a heavy seepage through the levee embankment near the toe. A closure exists at Montgomery Street Overpass. While the City does not currently have a documented plan for the closure, they are planning to acquire flood fighting / closure supplies to stockpile (i.e. muscle wall or similar) and would plan to install a closure at the overpass using these devices and or sandpile/sandbags. Given the flows are regulated by the Oroville Dam controlled releases, it is expected there would be sufficient warning time to install closure devices and prepare for flood fighting.

1. Unwanted Vegetation Growth
Description: Document the presence of vegetation
growth on the levee embankment or within 15-feet
of the levee toe with emphasis on vegetation that
may impact levee performance or flood fight
detection/intervention. Describe the location, size,
species of trees, brush, or other vegetation. Specify
if vegetation is contained in overbuilt sections,
particularly if it is reported that the levee was
designed to accommodate vegetation. Describe the
health of trees with specific attention to unstable,
dead or dying hazard trees. Make note of the
vegetation location in relation to the project
easement.

Summary: Dense vegetation in some areas of the waterside slope along with large trees (diameters ranging from 12 to 56-inches). Vegetation could complicate access to waterside slope (including to stormwater pipes), which could delay detection of performance issues and potential breach events. Larger trees also pose a risk for riverine erosion in event of treefall and root scour.

Observation(s):
2025-10038 : 14+30 : A single 56-inch diameter tree on the waterside levee slope (G) 2025-10017 : 48+50 : A 48-inch diameter tree stump was observed on the landside slope. Masonry retaining wall around the tree. Some erosion was observed on levee slope around the tree. (L) 2025-10010 : 55+30 : Multiple trees were observed extending close to bike path on waterside slope at this location. (G)
2025-10006 : 56+00 : Multiple trees on waterside slope, approx. 12 to 18-inches diameter (L)

2. Sod Cover
Description: Document the health and coverage
of the sod cover on levee slopes and crown.

Summary: Significant weed growth present within the sod cover along the levee landside slope. Coverage is inconsistent with bare patches exposing underlying soil. No consistent riverside sod was observed; the riverside slope has higher density tree growth with canopy that restricts sod growth.

Observation(s):
2025-0012 : 44+00 : Sod cover on landside slope near Sta 44+00; thick weedy vegetation present on slope.

The vegetative cover is cut and maintained near the toe of the slope but over-grown from mid-slope to crest.

Vegetation appears somewhat green but mostly yellow-brown. (L) 96 Item 3.

3. Encroachments
Description: Document any encroachments that
may impact levee performance or flood fight
detection/intervention including trash, debris,
unauthorized farming activity, structures,
excavations, or other obstructions present within
the easement area. Note if the encroachment(s)
have been previously reviewed by the levee
owner, and it was determined that they do not
diminish proper functioning of the levee.

Summary: A detailed evaluation of unauthorized encroachments within the project footprint is not in scope for field data collection. The upstream portion of the levee is a multi-use trail and public space incurring a number of encroachments including observation platforms, utilities, irrigation, park improvements such as benches, etc.

Observation(s):
2025-10040 : 10+00 : Elevated structure with wooden piers extending into waterside slope; piers are just above bike/walk path on waterside slope. (L)
2025-10033 : 28+30 : Utility manhole for fiber optic cables on landside berm (L) 2025-10030 : 30+50 : Concrete foundation was observed to be embedded in waterside slope and crown, close to crest. Opening at bottom of concrete foundation. (L) 2025-10016 : 49+00 : Masonry brick retaining wall on landside near Bedrock Park, typical design features such as weep-drains were not observed. The retaining wall condition did not appear to be maintained, the wall appeared to have slight tilt inward indicating rotation at the foundation, typical design features such as weep drains were not observed. Due to the observed condition, the wall presents a potential stability to the toe of the slope along this section of the levee. (L)

4. Closure Structures
Description: Document the closure structure type
and dimensions. Evaluate and describe the
condition of the closure structure. Are the placing
equipment, stoplogs, and other materials readily
available at all times? Are components clearly
marked and installation instructions/procedures
readily available? Have trial erections been
accomplished in accordance with the O&M
Manual?
Summary: Two potential closure structures of significance were identified at opening in the Highway 70 embankment. The closures have never been placed or needed to be placed. The City does not currently have a documented plan for the closures.

Observation(s):
2025-0003 : 112+50 : Oro Blvd E underpass under Hwy 70, approximately 70-feet wide. (G) 2025-10045 : 74+75 : Montgomery St underpass under Hwy 70, approximately 100-ft wide. Potential closure at this location would need to be at least 3-feet high. (G) 97 Item 3.

5. Slope Stability
Description: Document any slides, sloughs,
tension cracking, slope depressions, or bulges
present. Describe the physical dimensions of the
area impacted by slope movement. Document
historical slope instability locations, date of
incident, rehabilitation details, etc.

Summary: Multiple instances of slope instability were observed on the waterside slope, identified by apparent head scarps. At approximately Sta 49+00 an existing masonry brick retaining wall on landside presents a potential instability at toe of slope in this section of levee.

Observation(s):
2025-10009 : 55+00 : Location of potential old slope failure on waterside (L) 2025-10005 : 58+00 : Location of observed slope instability on waterside slope. Also observed scarp at this location. Multiple trees near waterside toe generally observed in this portion of the levee. (L) 2025-10003 : 62+80 : Location of scarp observed on waterside slope (L)

6. Erosion / Bank Caving
Description: Document erosion or bank caving on
the landward or riverward sides of the levee that
might endanger its stability. Describe the physical
dimensions of the erosion (length along the levee
and distance into the levee). Document historical
erosion locations, date of incident, rehabilitation
details, etc.

Summary: Multiple instances of erosion and bank caving were observed on both the landside and waterside slopes. Erosional features on the waterside slope often extended from the crown to the bike path. These observations were not a significant consideration for the Riverine Erosion performance assessment. Some locations had significant erosion near the crest and old concrete foundations embedded in the slope.

7. Settlement
Description: Document irregularities or
depressions in the levee crown associated with
settlement. Field observations will be compared
with existing records to evaluate the historical
changes and assess if levee overtopping can occur
more frequently than designed.

Summary: A baseline levee crest survey or as-built was not available to compare levee crest settlement.

There was no observable significant settlement identified during the field data collection. The levee foundation material (granular, cohesionless) is typically not susceptible to long term settlement.

Observation(s):

8. Depressions / Rutting
Description: Document scattered, shallow ruts,
potholes, or other depressions on the levee that are
unrelated to levee settlement. Take note of areas of
the levee crown, embankments, and access road
crowns that are not draining properly or exhibit
ponded water.

Summary: No instances of depressions or rutting were observed.

Observation(s):

9. Cracking
Description: Document longitudinal, transverse,
or desiccation cracks and identify if vertical
movement along the crack is present. Note if
cracks extend continuously through the levee
crest. Describe the physical location and
dimensions of the crack (length along the levee,
crack width, vertical displacement, etc.).

Summary: No significant cracking in the earthen embankment sections were observed.

10. Animal Control
Description: Document observations of animal
burrowing activity or other animal related
disturbances to the levee prism. Make note of the
levee owner’s animal burrow control program
including detail on the elimination of active
burrowing and the filling in of existing burrows.

Summary: Animal burrowing activity of approximately 2-24-inch diameter openings were identified in many areas along the length of the levee on both the riverside and landside levee slopes. In most cases, the burrowing activity is in atypically wide levee sections.

Observation(s):
2025-0018 : 47+00 : Multiple animal burrows 12 to 24-inches diameter observed on landside slope (L) 2025-10032 : 25+60 : Multiple animal burrows 6 to 12-inches diameter observed on waterside slope (L) 2025-10029 : 31+00 : Animal burrow approx. 12-inch diameter near waterside crown (L) 2025-10008 : 55+80 : Approx. 10 animal burrows, 4 to 8-inches diameter (L)

11. Culverts / Discharge Pipes (This item includes
both concrete and corrugated metal pipes.)
Description: Document the location, size,
material type, closure type, and condition of any
culverts or discharge pipes that cross through,
beneath, or near the levee prism. Describe the
condition of visible portions of the culvert and its
closure apparatus. Describe the size and location
of breaks, holes, cracks in the discharge
pipes/culverts that would result in significant
water leakage. If the levee owner has verified the
interior condition of pipes using television camera
videotaping or visual inspection methods, include
the date of that inspection and a summary of
defects, joints, etc. Are breaks, holes, cracks, root
penetrations present? Do joints appear to be closed
and the soil tight? Refer to NASSCO PACP
Structural and O&M defect codes, if applicable.

Document the type and condition of culver gates.

Do gates open and close freely to a tight seal or
minor leakage? Is corrosion occurring? Are gate
operators in good working condition and are
properly maintained? Is the sill free of sediment
and other obstructions? Document the frequency
of gate and/or lifter maintenance. "
Summary: Multiple stormwater discharge pipes were observed, with several lacking closure devices and others difficult to access due to vegetation and erosion.

Observation(s):
2025-0013 : 182+35 : Double barrel concrete box culvert through Hwy 70 embankment. No wingwall on waterside, wingwall on landside. (L)
2025-10035 : 19+50 : 24-inch concrete culvert outlet near waterside toe. Concrete pipe is in good condition (i.e. no cracks, holes, root penetrations observed). No closure present. (L) 2025-10031 : 29+30 : 18-inch culvert outlet near waterside toe, approx. 32-feet below bike path on waterside slope. No closure device (e.g. flap gate) was observed. (L) 2025-10025 : 43+00 : Approx. 12-inch corrugated metal pipe near toe of waterside slope. No closure device (e.g. flap gate) was observed. (L)
2025-10013 : 41+30 : Metal pipe with metal flap gate near Bedrock Park. Pipe diameter is approximately 1.5 to 2-feet. Pipe is embedded into original concrete faced levee. No blockages or vegetation near opening.

Condition deeper within pipe is unknown. (L)

12. Riprap Revetments & Bank Protection
Description: Document riprap revetments by
identifying the riprap size and dimensions. Verify
field conditions match design, if known. Record
displacement or stone degradation that could pose
an immediate threat to the integrity of channel
bank. Note presence of woody vegetation present
in the riprap armor.

Summary: No engineered bank protection or revetment exists along levee toe. Observed exposed cobbles on levee slope in several areas.

Observation(s):

13. Revetments other than Riprap
Description: Document condition of the existing
revetment protection.

Summary: The original levee built in 1907 was a concrete faced embankment. Dredge operations has covered this concrete panel erosion protection in all locations except for the reach along Bedrock Park. (Station 46+00-Station 52+80)
Observation(s):
2025-10012 : 46+00 : 52+80 : Levee crest for Stations 46+00 to 52+80 near Bedrock Park, showing original 1907 concrete-faced levee. Concrete appeared to be in relatively good condition. Weathering, exposed aggregates, and vegetation growing through joints were observed, however, we did not observe extensive cracking, damage, or displacement of the concrete. (L)

14. Underseepage Relief Wells / Toe Drainage
Systems
Description: Document the presence and
viewable condition of underseepage mitigation
features including toe drains, relief wells or other
features. Record observations which would
indicate that the drainage systems will not function
properly during the next flood. Document
historical performance of these systems during
previous high water. Did the toe drainage systems
and/or pressure relief wells function properly
during the last flood event? Was sediment
observed in horizontal system (if applicable)?
Detail maintenance records that indicate regular
cleaning. Document findings from relief well
pump tests including date of test.

Summary: No underseepage relief wells or toe drainage systems were observed nor documented for the levee.

Observation(s):

15. Seepage
Description: Document any evidence or history of
unrepaired seepage, saturated areas, or boils.

Document historical internal erosion locations,
date of incident, rehabilitation details, etc.

Summary: There is a history of seepage at Bedrock Park, near the transition of original 1907-built concretefaced levee to later overbuilt levee section. Heavy seepage was recorded during 1986 and 1997 flood events, although no breach of levee embankment has ever occurred. Flood fighting was performed during the 1997 flood event. No repairs have been made at the location of historical seepage.

Observation(s):
2025-0017 : 50+00 : Location of historical seepage during the 1986 and 1997 flood events. No breach of levee embankment occurred during or after the seepage events. (G) 102

CITY OF OROVILLE

STAFF REPORT
TO: MAYOR PITTMAN & COUNCIL MEMBERS
FROM: CHRIS TENNS, FIRE CHIEF AMY

BERGSTRAND, DIRECTOR HOUSING AND COMMUNITY SERVICES
RE: 2026 SUPPLEMENTAL BENEFITS FUND APPLICATION
DATE: OCTOBER 6, 2026

SUMMARY
The City Council shall consider the submittal of an application to Supplemental Benefits Fund (SBF) Committee for the purchase of one (1) four door Polaris Ranger Fire and Rescue UTV, including onboard fire pump, medical and rescue equipment, emergency lighting, communications equipment and dedicated transport trailer.

Since the license has not yet been signed, DWR has agreed to front funding of $200,000/year for projects until the FERC License is approved.

The current Notice of Funding Availability (NOFA) was released on August 24, 2026, in the amount of $450,000, with proposals due by October 8, 2026.

The Oroville Fire Department is requesting approval to apply for the purchase one (1) four door Polaris Ranger Fire and Rescue UTV, including onboard fire pump, medical and rescue equipment, emergency lighting, communications equipment and dedicated transport trailer up to $76,000.

The Oroville Fire Department currently responds to approximately 40-50 incidents each year associated with the Feather River, Afterbay and surrounding recreational areas. Although the existing fire engines, ambulances and other emergency resources provide an effective response to reasonable accessible by conventional roadways, many areas adjacent to the river contain narrow trails, unimproved access routes, riverbanks, pedestrian pathways, open space areas, and locations where traditional emergency apparatus cannot effectively operate. The proposed equipment would provide the Oroville Fire Department with a specialized emergency response capability that would improve emergency access, public safety and environmental protection.

FISCAL IMPACT
The $5,000 match will be funded from the District Sales Tax Fund 1021152 8030 Vehicles.

Should the grant be awarded, the fiscal impact will be addressed when the budget is established for the activities.

ACTION REQUESTED -
ADOPT RESOLUTION NO. 9486 - AUTHORIZING THE SUBMITTAL OF 2026 SUPPLEMENTAL BENEFITS FUND APPLICATION IN THE AMOUNT OF $76,000.00; AND IF SELECTED, THE

FROM: AMY BERGSTRAND, DIRECTOR

HOUSING AND COMMUNITY SERVICES
RE: RESOLUTION IN SUPPORT OF THE VETERANS AND AFFORDABLE HOUSING BOND ACT OF 2026
DATE: OCTOBER 6, 2026

SUMMARY
The City Council shall consider adopting a resolution supporting The Veterans and Affordable Housing Bond Act of 2026, which authorizes $11.25 billion in state general obligation bonds to fund several housing affordability programs.

DISCUSSION
The Veterans and Affordable Housing Bond Act of 2026 would authorize the state to issue $11.25 billion in general obligation bonds to fund several categories of existing housing programs, including:
 Multifamily Housing Program
 Infill Infrastructure Grant Program
 CalHome Program
 Farmworker Housing
 Tribal Housing Grant Program
 Higher Education student housing
 Local pilot programs
 Veterans’ Housing
Major Provisions:

The Veterans and Affordable Housing Bond Act of 2026 is a measure placed on the November 3, 2026, ballot by the Legislature that would replenish existing housing programs for the development, preservation, and rehabilitation of affordable housing projects.

Additionally, the measure would provide funding to support the development of youth and veteran housing and promote homeownership in California. Here are the specific funding allocations proposed in the ballot measure:
 $5.1 billion to the Multifamily Housing Program.
 $1.25 billion to provide farm and home aid for veterans under the Veterans’ Farm and Home Purchase Act of 1974.
156
Item 5.
 $1.15 billion to the Housing Rehabilitation Loan Fund, to be used for supportive housing. Up to 15% shall be used to assist in the acquisition, conversion, or rehabilitation of interim housing to permanent housing.  $750 million to the Portfolio Reinvestment Program to preserve existing affordable housing projects.
 $600 million to the CalHome Program.
 $500 million to the Home Purchase Assistance Fund for home purchase assistance programs.
 $500 million for the Infill Infrastructure Grant Program to assist in the construction and rehabilitation of infrastructure to support high-density, affordable, and mixed-income housing in infill locations.
 $450 million to the Joe Serna, Jr. Farmworker Housing Grant Fund to support housing for agricultural employees and their families.
 $350 million for new affordable student housing projects.  $200 million to fund the acquisition and rehabilitation of unrestricted housing units and attach long-term affordability restrictions on housing units.  $200 million to the Affordable Housing Innovation Fund to assist local housing trust funds in developing, owning, lending, or investing in affordable housing.  $200 million to the Tribal Housing Grant Program to help tribes rebuild and reconstitute their communities.
 $150 million for youth housing defined as housing for current or former foster youth, homeless minors or youth, or youth at risk of homelessness.

Background:

The state uses general obligation bonds to fund various housing programs. Bonds are a way the state borrows money to cover the up-front costs of a development and then repays the money plus interest over time.

Proposition 1 would allow the state to sell $11.25 billion in general obligation bonds for housing purposes. This amount consists of (1) a $10 billion bond for a variety of housing programs that would be repaid by the State’s General Fund and (2) a $1.25 billion bond that would be repaid by veterans’ payments on their home loans.

According to the nonpartisan Legislative Analyst’s Office, Prop. 1 would provide subsidies for as many as 40,000 multifamily rental units and about 1,200 beds for university students. The funds could also help up to 40,000 households, including about 2,100 veterans, with homeownership.

This City of Oroville has a long history of utilizing CalHome Program funds and CalHome Program Income fund to help fund our First Time Homebuyer Program and Owner-Occupied Rehabilitation Programs. Additionally, staff is generally in support of Veteran Housing Assistance Programs.

According to the nonpartisan Legislative Analyst's Office, the state General Fund cost to repay the bond would be $500 million to $600 million annually for about 25 years. The estimated annual cost would be about one-quarter of 1% (0.25%) of the state’s total General Fund budget.
157
Item 5.

Existing Policy:

The City of Oroville is a member of the League of California Cities and supports Cal Cities’ 2026 Advocacy Priority to secure investments to increase the supply of affordable housing, including state and federal programs that assist in providing financing for affordable housing, as well as the development of fiscal tools and incentives to assist local governments in their efforts to encourage housing and finance the infrastructure to support housing and the establishment an ongoing state commitment for funding affordable housing.

CITY OF OROVILLE

STAFF REPORT
TO: MAYOR PITTMAN & COUNCIL MEMBERS
FROM: TIM KABER, DIRECTOR OF PUBLIC WORKS
RE: 2026/2027 IN-HOUSE PAVEMENT MAINTENANCE PROJECT LIST DATE: OCTOBER 6, 2026

SUMMARY
The City Council will receive an updated list of pavement maintenance projects to be performed by in-house Public Works crews. The funding for these projects is within the adopted 2026/2027 City of Oroville budget.

DISCUSSION
The City budget for the 2026/2027 fiscal year contains $750,000 for in-house pavement projects, which is an increase from $40,000 in the previous budget. The objective for the in-house pavement projects is to prolong pavement life in order to get each road section to the next major maintenance project. Each listed road project will be completed under the $75,000 limit for Public Works projects.

Staff identified streets that would best benefit from minor maintenance and provide for extended pavement life. Streets that are already in poor shape were not considered, as the required maintenance/repair is too costly for Public Works crews, and would not provide an adequate return on investment.

Each street listed is an equal priority and will be completed as staffing and conditions permit.

FISCAL IMPACT
There is no fiscal impact. Funds were approved in the current 2026/2027 budget. Funding is from State road funds allocations.

ACTION REQUESTED -
RECEIVE FOR INFORMATION OR PROVIDE DIRECTION TO STAFF.

STAFF REPORT
TO: MAYOR PITTMAN & COUNCIL MEMBERS
FROM: AMY BERGSTRAND, DIRECTOR OF HOUSING AND COMMUNITY

SERVICES
RE: CYCLE 2 PERMANENT LOCAL HOUSING ALLOCATION (PLHA) FIVE YEAR PLAN AND APPLICATION FOR YEARS 2024-2028
DATE: OCTOBER 6, 2026

SUMMARY
The City Council shall conduct a public hearing to solicit comments regarding the submittal of a Cycle 2 PLHA 5-year Plan and the submittal of an application to the Department of Housing and Community Development (HCD) Permanent Local Housing Allocation (PLHA) for approximately $498,525 for the development of an Affordable Housing Recovery Program to increase the supply of affordable housing, and direct staff to implement the grant if awarded. This 2nd cycle will cover implementation years from 2024-2028.

DISCUSSION
Pursuant to the Building Homes and Jobs Act Senate Bill 2 (SB2, 2017), the Department of Housing and Community Development (HCD) has been collecting a $75 recording fee on real estate documents to increase the supply of affordable homes in California. The intent of the bill is to provide permanent, on-going source of funding to Local Governments for housing-related projects and programs that assist in addressing the unmet housing needs of their local communities.

The updated 2024-2028 PLHA Formula Program Guidelines streamline and enhance program delivery. As part of the updates, the original ten eligible activities were consolidated into three new activity categories:
 Rental Activities
 Affordable Owner-Occupied Workforce Housing Activities  Homelessness Assistance Activities
Jurisdictions must apply for each annual allocation separately as the Notice of Funding Ability (NOFA) is released by HCD. Currently, staff would be able to claim years 2024 and 2025.

Staff has reviewed the eligible activities and proposed the use of the funds for developing a new Affordable Housing Recovery Program designed to acquire and rehabilitate foreclosed or vacant properties to be sold as affordable ownership housing under §301(a)(2)(E).

Staff plans to use the funds to redeem existing city borrower’s, mortgages that are currently in default and at risk of foreclosure. The City will then begin foreclosure on the City’s behalf and if the home 199
Item 11.
returns to the City, the City will make necessary repairs and sell it to new income eligible borrower with a 20-year affordability restriction. If the home is sold at auction, the City will use the reimbursement of funds to redeem an additional property or purchase a vacant home to rehabilitate and place for sale. The intent is to return and keep affordable homes to the City’s housing stock and to improve neighborhoods by eliminating the vacant home.

Once Council gives direction, staff will prepare and submit the grant application, and if awarded, will use a portion of the grant funds for staff time to implement the grant.

FISCAL IMPACT
None. The grant funds will support the anticipated program and five percent (5%) of the grant funds may be used for administrative costs.
