Levee Inspection Reference Guide

Levee Inspection Report Reference Guide

Levee Inspection Reference Guide
The purpose of the Levee Inspection Reference Guide is to provide supporting direction for conducting formal and special levee inspections, determining item ratings and finalizing the results of the inspection. This Checklist is to be used with the Standard Operation Procedures (SOP) for Levee Inspections and Site Visits.

A. Definitions:

Approved Alteration - Any action that builds upon, alters, improves, moves, or occupies a levee system. For federally authorized levee systems, a USACE Section 408 permission has been issued. For non-federally constructed and locally maintained levee systems, the levee sponsor is aware of and has approved the alteration. Often, observations of approved alterations are handled under the Encroachment item in the Levee Inspection Checklist. These observations should be noted as such and details included in the observation descriptions.

Encroachment - A non-project item such as trash, debris, structures, obstructions or unauthorized/inappropriate activities within the easement/right-of-way of the levee. For federally authorized levee systems, no USACE Section 408 permission has been issued. For non-federally constructed and locally maintained levee systems, the levee sponsor is unaware of and/or has not approved the non-project item or activity.

Feature - A component of a levee segment/system (e.g. Embankment, Floodwall, Channel, etc.). Levee segments/systems may have multiple Features that function together to exclude water from a defined leveed area. Main Features have their own section in the Levee Inspection Checklist.

Formal Inspection - A pre-scheduled comprehensive levee inspection by a team of subject matter experts led by a professional engineer or professional geologist to (1) document levee condition, (2) assess progress of ongoing risk management activities, (3) inform risk assessments and new risk management recommendations, and (4) include specific evaluations or testing, such as exercising closures or performing relief well pump tests.

Item - A characteristic of a levee Feature (e.g. Encroachments, Sod Cover, Seepage, etc.) that is used to assess the condition of the levee, inform risk assessments, and/or evaluate adequacy of operations and maintenance.

Levee Segment - A levee segment is a discrete portion of a levee system that is operated and maintained by a single entity. A levee segment may be composed of one or more levee features.

Levee System or Levee - A man-made structure that does not cross a watercourse, usually an earthen embankment or floodwall, designed and constructed with the principle function of excluding flood waters for a limited range of flood events from a portion of the floodplain (referred to as “leveed area”).

National Flood Insurance Program (NFIP) - A voluntary program administered by the Federal Emergency Management Agency (FEMA) to mitigate flood losses through community-enforced building and zoning ordinances and to provide property owners with access to federally-backed flood insurance.

Negative Finding - A conclusion that there is sufficient information to determine that a specific criteria of 44 CFR 65.10 for the NFIP has not been met as a result of a levee inspection.

Non-Project Segment - a form of manmade high ground which a levee system/segment ties into, whose existence and performance is necessary for excluding flood waters from the leveed area, but is not under any USACE authority.

Observation - A specific location (point or line) where an Item is evaluated and rated based on the rating guidelines (e.g. an area of levee that has less than 50% sod coverage).

Observation Location Description - Information that further describes the observation location such as land or waterside of the levee or proximity along the slope or crown that provides the reader with sufficient information to find the observation during future maintenance activities or inspections. Observation location descriptions may include the following: landside toe, landside toe and slope, landside levee slope only, landside slope and crown, slopes and crown, crown, slopes, toes, waterside toe, waterside toe and slope, waterside levee slope only, waterside slope and crown, other.

Observation Number - A numeric value that is used to identify a specific observation location during an inspection.

Positive Finding - A conclusion that there is sufficient information to determine that a specific criteria of 44 CFR 65.10 for the NFIP has been met as a result of a levee inspection.

Rating Guidelines - Established parameters to assist an inspector in assessing the visual condition of a specific location (point or line) or multiple locations that serve as the rationale for a final Item rating.

Special Inspection - A formally documented visual inspection that is requested by the levee sponsor or required due to changed conditions or to document performance.

Use of the Levee Inspection Checklist:

General Notes:
• Each individual levee segment will have its own inspection results. • Include only the feature sections of the Checklist that apply to the segment being inspected.
• The Levee Inspection Summary and the section labeled "General Items" is required for every formal and special inspection. • Specific data fields have been included in the National Levee Database (NLD) to document frequency of inspection, testing or operation and condition for the following Features or Items: pipes, gates, relief wells, toe drains and closures. Applicable tables should be attached to the Levee Inspection Report (see Appendix J of the SOP for Levee Inspections and Site Visits. Specific corrective recommendations should not be included with the inspection results. Inspection results should be used to develop risk-informed recommendations as part of the Levee Risk Management Summary (See EC 1165-2-218). • If there is a non-project segment as part of a levee system with a federally authorized segment that rights-of-entry could not be obtained, then visual observations should be documented in a Site Visit Summary.

Specific Levee Inspection Features Sections and Items:
• The items labeled “Culverts and Discharge Pipes” includes all gravity flow and pressurized pipes that pass over or through the levee and its foundation, as well as pipes away from the levee. Judgment and consistency should be exercised when determining if pipes should be rated under the Levee Embankment Feature or the Interior Drainage Feature “Culverts and Discharge Pipes” rated items. Pipe closures and drainage features should be rated in their respective items under the Interior Drainage System Feature. This includes all associated gates and drainage ditches, ponding areas and structures that are functioning as interior drainage components along the levee. The pump station feature has a separate item for intake and discharge pipes associated with those Features. • The items labeled “Closure Structures” includes all closure structures, sandbag and earthen closures, stop logs and gates. Conduit and culvert closures are documented and rated in the appropriate items within the Interior Drainage System Feature. • The starting and stopping location for embankments, floodwalls and closures shall be determined in a case-by-case basis. • The section labeled “Flood Risk Management Channels” includes channels that have been constructed in association with the levee system. This section may also be used to inspect channels independent of levees. For “shoaling”, the rating guidelines describing vegetation in a shoal are intended to document the permanence of the shoal and its likely impact on channel integrity or flow capacity. • The Feature section labeled “Pump Stations” includes the structure of the pump station and all associated intake/discharge pipe, mechanical/electrical systems and equipment.
• For “Interior Drainage System”, “Flood Risk Management Channels”, and “Pump Stations”, conditions of Items that impact levee embankments or floodwalls (e.g. ditches, ponding areas, bank stability or erosion) should also be rated under the appropriate Levee Embankments or Floodwalls section to reflect the impact on levee integrity.

C. Observation Ratings:

General Notes:
• For each Observation noted during the inspection, the inspector will apply a rating to the Observation based on the rating guidelines associated with the corresponding Item. Overall Item ratings are assigned based on summarizing all Observations for that Item. • When an observation is associated with more than one feature (e.g. observed erosion identified in or near a levee embankment and a flood risk management channel), observations shall be recorded, described, and rated within each appropriate feature and item. • Inspectors should document any observation/activity that can be visually seen from the levee that may adversely affect the integrity of the levee, even if the concern is beyond the limits of the easement/right- of-way, with documentation that the Observation is outside the easement/right-of-way. It is understood that resolution of these instances may be beyond the control of the levee sponsor. • Observations associated with approved Section 408 permissions or levee sponsor permits for modifications should be rated under the corresponding Item and feature or under “Encroachments” and documented as such.
• Seepage Observation ratings should consider information collected during recent flood events. • Most levee systems have components that may require testing or inspection to occur at a frequency that is outside of or more frequent than during pre-scheduled formal inspections to assess their internal condition or operability. These components usually are culverts and discharge pipes; relief wells and toe drains; closures, gates, and valves; and operational systems in pump stations. Requirements for testing/inspection of these components are typically prescribed in the levee’s operations and maintenance manual. A field observation must be recorded of visible conditions of each component during an inspection. This will be used to supplement internal conditional assessments using PACP defect codes for culverts and discharge pipes and toe drains; internal conditional assessments from pump testing for relief wells; and operational adequacy from testing/installation records for closures, gates and valves, and operational systems in pump stations in the Item Rating determination.
• If Districts schedule a walk-through pipe inspection (in accordance with EM 1110-2-2902 and EM 385-1-1) in conjunction with a levee inspection, inspectors must document both the interior conditions by assigning a PACP defect code and the pipe’s exterior conditions with an inspection Observation Rating.

General Guidelines for Assigning Observation Ratings:

Acceptable Minimally Acceptable Unacceptable
An “Acceptable” observation rating generally
means that it has been operated and
maintained in a way that meets the intent of
the “Acceptable” rating guidelines herein, and
is not expected to have a negative impact on
performance.

A “Minimally Acceptable” observation rating
generally means that it has deficiencies that
should be corrected, but are not currently
expected to have a negative impact. If not
corrected, these deficiencies could lead to a
negative impact on performance.

An “Unacceptable” observation rating
generally means that it has serious deficiencies
that require correction because these
deficiencies are expected to have a negative
impact on performance.

Documentation of the levee inspection observations should include, at a minimum:
• Observation number associated with the point or line
• Observation rating of “Acceptable”, “Minimally Acceptable” or “Unacceptable” based on rating guidelines for the Item • Observation location description
• Levee station, river mile and/or GPS latitude/longitude associated with the point or line • Description of the observation which is a detailed narrative that explains why an observation was documented and the rationale for the observation rating Levee Inspection Report Reference Guide

Page 4 of 4 ends

• Photo associated with the observation point or line.
• Photo num ber related to a photograph of the observation point or line.

D. Item Ratings:
• Item ratings will be determined by considering all associated Observation ratings comprehensively. Rationale for overall Item ratings must be documented in the Levee Inspection Checklist.
• If the Item does not exist within the levee segment, the Item should be rated “N/A”.

General Guidelines for Assigning Item Ratings:

Acceptable Item Minimally Acceptable Item Unacceptable Item Observations are rated “Acceptable”, or one or
more observations are rated “Minimally
Acceptable” but the number or severity of
“Minimally Acceptable” Observations
collectively is not expected to have a negative
impact on performance. No Observations were
rated as “Unacceptable.”
One or more Observations are rated
“Minimally Acceptable” or one or more
Observations were rated “Unacceptable” but
the number or severity of Observations
collectively are not currently expected to have
a negative impact, but if not corrected
deficiencies could lead to a negative impact on
performance.

One or more Observations are rated
“Unacceptable” and the number or severity of
Observations collectively has are expected to
have a negative impact on performance.

1 1.1 Background and Purpose
This report is part of the Sacramento Area Flood Control Agency’s (SAFCA) due diligence review for compliance with the California Department of Water Resources (DWR) Urban Levee Design Criteria (ULDC) and the Federal Emergency Management Agency (FEMA) requirements of the National Flood Insurance Program (NFIP) regulations as cited in the Code of Federal Regulations in Title 44, Chapter 1, Section 65.10 (44 CFR 65.10) for the Robla-Arcade Levee System (RALS), prepared in response to the regulatory requirements of ULDC. Preparation of this report entailed gathering information related to the RALS, including design and as-built data, geotechnical data, data from the maintaining agencies regarding closure structures, retaining walls, floodwalls, and penetrations through the levee, and conducting necessary visual observations/inspections/analysis. The data has been evaluated to determine if any segments of the RALS do not meet ULDC criteria.

Senate Bill 5 (2007) required the California DWR develop a set of urban levee design criteria that would be applied to all levees which provide an urban level of protection. In May of 2012 , the ULDC Criteria was finalized. Since the RALS protects an urban population, these ULDC criteria were used to assess the levee’s compliance and SAFCA’s due diligence.

Mead & Hunt is a member of SAFCA’s consultant team and is responsible for the following components to determine ULDC compliance and due diligence:
1) ULDC Section 7.12 – Levee encroachment data collection and evaluation criteria 2) ULDC Section 7.13 – Levee penetrations analysis and condition assessment 3) ULDC Section 7.14 – Floodwalls, retaining walls, and closure structures structural analysis and condition assessment
4) ULDC Section 7.17 – Wind setup and wave runup analysis 5) ULDC Section 7.20 – Operations and Maintenance (O&M) manual review

The purpose of this report is to present the study objectives, criteria, assumptions, study methodology , results for the above components, and their respective determination as it pertains to ULDC compliance.

This report is a supplement to previously completed reporting regarding encroachments, penetrations, floodwalls, closure structures, retaining walls, wind setup and wave runup, and O&M manuals. The previous Mead & Hunt Certification Report (Mead & Hunt, Inc., 2015) was used as a reference for this report.

1.2 Need and Scope
SAFCA’s objective is to provide the Sacramento region with increased flood protection. The flood protection features under SAFCA’s jurisdiction are broadly categorized under the following groups – Natomas Levees, North Sacramento Streams Levees, American River Levees, Sacramento River Levees South of Confluence, South Sacramento Streams Group Levees, and Folsom Dam Auxiliary Spillway (see Exhibit 1). SAFCA’s ULDC and FEMA certification efforts have been divided into five basins, as shown in Exhibit 1. The RALS is located in the North Sacramento Streams group.

2 In order to maintain continuous accreditation of the affected levees and to identify what actions, if any, are required to meet the State’s ULDC 200-year level of flood protection requirements, SAFCA has undertaken this evaluation. Mead & Hunt has performed the following activities that pertain to the RALS ULDC efforts (referenced in Section 1.1):
• In 2014, Mead & Hunt developed an Encroachment White Paper, which considered criteria from ULDC, FEMA, and USACE. This white paper was used as a basis for the analysis and reporting of encroachments, as supported by this effort. The white paper is documented in (SAFCA Sacramento FEMA Certification White Paper for Addressing Encroachments, 2014) . • In 2015 Mead & Hunt reported on encroachments, penetrations, floodwalls, retaining walls, closure structures, wind setup and wave runup analysis, and O&M manual review as part of SAFCA’s previous FEMA Certification efforts for multiple levee systems, of which RALS was included. That effort is documented in (Mead & Hunt, Inc., 2015). • A visual inspection of the RALS was conducted in December 2023 and levee encroachments, penetrations, floodwalls, retaining walls, and closure structures database information were assessed and revised accordingly. As discussed in this report, applicable analyses and assessments were conducted.
• Review of available data and reports, field observations, supplemental inspection reports, revised design water surface elevation data, and updated top-of-levee surveys. • Review of the pipe condition inspection programs with facility owners, including:
o City of Sacramento, Department of Utilities – Stormwater and Sewer o City Of Sacramento, Department of Utilities – Water
o Sac Sewer (Sacramento Regional Sanitation District/Sacramento Area Sewer District) o PG&E natural gas
• Review of annual trial exercise of emergency closure gate programs with the City stormwater and wastewater operations staff.
• Penetration assessment screening and analysis completed as part of this certification effort included using the previous methodology documented in (Mead & Hunt, Inc., 2015) and is further documented in Appendix A. The updated assessment is based upon current conditions. • Floodwalls, retaining walls, and closure structures were also assessed and analyzed, as part of this certification process, as discussed in this report. • Updated the wind-wave analysis to include the most current wind speed data, incorporated new topography provided by MBK, included the 2024 top-of-levee survey data from PSOMAS, and updated the methodology for accuracy.
• Compiling data on the City of Sacramento’s most recent Union Pacific Railroad (UPRR) stoplog trial closures, witnessed by Mead & Hunt.
• Review and evaluation of whether the RALS meets ULDC requirements as it pertains to ULDC Sections 7.12 – Encroachments, 7.13 – Penetrations, 7.14 – Closure Structures, 7.17 – Wind Setup and Wave Runup, and 7.20 – Operations and Maintenance Manuals. All other ULDC criteria is being evaluated by others.
• This report is not intended to be a full compilation of background information and evaluations for ULDC criteria. It is intended to serve as a supplement to the previously documented Mead & Hunt analyses and reports, mentioned previously.

3 1.3 Report Organization
This report is divided into eight sections. Section 1 is an introductory section that describes the background, need, scope, and organization of this report. Sections 2 through 6 address the five ULDC criteria for which Mead & Hunt is responsible (listed in Section 1.1) and contain objectives, criteria, assumptions, study methodology, and results of the study for each component as they pertain to ULDC Criteria for modifications to these responsible areas. Section 7 summarizes the results of this report.

Section 8 lists the applicable References.

4 2.1 Purpose
Levee encroachments must comply with DWR ULDC encroachment criteria, as well as United States Army Corps of Engineers (USACE) criteria for Periodic Inspections under PL 84-99, Federal Emergency Management Agency (FEMA) criteria, and the Central Valley Flood Protection Board (CVFPB) Title 23 requirements. The purpose of the levee encroachment analysis conducted as part of this effort was to assess updated and supplemental information of existing encroachments for compliance with ULDC and other regulatory criteria. Mead & Hunt’s previous analyses in 2014 and 2015 for RALS informed this effort and established the foundation for these criteria.

2.2 Criteria
Levee encroachments were evaluated on the basis of four sources of criteria – ULDC (the main focus of this report), FEMA, USACE, and CVFPB – which are elaborated upon below. The different criteria were consolidated in an Encroachment White Paper (SAFCA Sacramento FEMA Certification White Paper for Addressing Encroachments, 2014).

2.2.1 ULDC Criteria
Section 7.12 of the ULDC addresses levee encroachments excluding penetrations, floodwalls, retaining walls, closure structures, and levee vegetation. ULDC requires encroachment analysis to consider the following when rendering this opinion: type, age, condition, performance history of the encroachment, impacts on the levee/floodwall structural integrity, impacts on the hydraulic effect on the channel and floodway, and impacts on the operation and maintenance of the levee/floodwall. Further, a hazard assessment needs to be performed for each existing encroachment, and encroachments found to have a high hazard require a full engineering evaluation to demonstrate whether the hazard is acceptable or not.

2.2.2 USACE Criteria
USACE criteria requires that anything over, under, or through the levee and within the project easement must have a valid CVFPB permit and a No Objection Letter issued by the USACE must be annotated in project as-built drawings or noted in the O&M manual. USACE classifies levees as “Acceptable,” “Minimally Acceptable,” or “Unacceptable” based on the condition of encroachments and other factors. The inspection criteria are found in a document titled USACE Levee Inspection Checklist, provided in Exhibit 2 of (Mead & Hunt, Inc., 2015). A levee is deemed unacceptable from the encroachment perspective if the encroachments are likely to inhibit operations and maintenance, emergency operations, or negatively impact the integrity of the levee. Levees are deemed minimally acceptable when trash, debris, unauthorized farming activity, structures, excavations, or other obstructions are present, or inappropriate activities are noted to be corrected, but will not inhibit operations and maintenance or emergency operations.

5 2.2.3 CVFPB Criteria
The California regulations for levee and floodway encroachments are set forth in Title 23, which describes the CVFPB duties for enforcement. Title 23 provides standards for the construction, maintenance, and protection of adopted flood control plans, which covers encroachments.

2.2.4 FEMA Criteria
Prior to the preparation of this report, Mead & Hunt prepared a white paper (SAFCA Sacramento FEMA Certification White Paper for Addressing Encroachments, 2014) that included criteria based upon FEMA and ULDC Criteria to be adopted for the classification of encroachments to address FEMA’s maintenance criteria, in accordance with 44 CFR 65.10(d). The white paper describes our approach to evaluation, which is intended to determine the likelihood of identified encroachments to inhibit operations and maintenance, emergency operations, or negatively impact the integrity of the levee. The Levee Maintenance Agencies (LMA)s and the CVFPB were provided the opportunity to review the approach. The LMAs were consulted to obtain input on how the various features could potentially impair maintenance and operations. The potential for an encroachment to negatively impact the levee system integrity was judged based on technical evaluations and compliance with criteria that are set forth to manage risk. Upon identification of encroachments that contribute to risk, Mead & Hunt classified encroachments as:
• Significant Threat to Levee Integrity (Category 1A)
o Imminent threat to integrity of the levee; must be remediated before levee certification.
• Low Hazard (Category 1B)
o Lesser threat to the integrity of the levee; impedes operation and maintenance; must be fixed or removed within three years of levee certification • Non-Compliant (Category 2)
o Doesn’t comply with ULDC; must be fixed or removed within ten years of levee certification.

The Encroachment White Paper, reviewed by SAFCA’s previous Board of Senior Consultants (BOSC) is provided in (SAFCA Sacramento FEMA Certification White Paper for Addressing Encroachments, 2014). Flowcharts showing the analysis pathways for major encroachment categories are provided in Exhibit 2 of (Mead & Hunt, Inc., 2015).

2.3 Methodology
A two-step approach was adopted for the encroachment analysis, which is described in detail in our previous efforts (Mead & Hunt, Inc., 2015) and the Encroachment White Paper (SAFCA Sacramento FEMA Certification White Paper for Addressing Encroachments, 2014) . As part of this current due diligence review, there were no modifications to the previous methodology described in the documents referenced in this section. Due to the voluminous nature of this material, that information was not reproduced here. Penetrations and associated structures, floodwalls, retaining walls, and closure structures were analyzed based on their own specific criteria in Sections 3 and 4, as documented in this report.

6 2.4 Results
A field investigation conducted in April and June 2024 (by Mead & Hunt) verified encroachment data. The total number of encroachments for this levee system is 119 (of which 14 are linear encroachments). This does not include any penetrations or associated structures, closure structures, retaining walls, or floodwalls (reported separately in Sections 3 and 4 of this report). Exhibit 2A of this report shows a map summary of all RALS encroachments. Additionally, Exhibits 3A1 and 3A2 show a table summary of all RALS encroachments and linear encroachments, respectively. During the 2024 field investigations and review of existing data, no high-risk encroachments were flagged for RALS by Mead & Hunt. This was further confirmed by MBK.

2.5 Due Diligence Review; ULDC and FEMA Compliance
In 2013 and 2014, SAFCA performed an inventory of encroachments along the RALS (Mead & Hunt, Inc., 2015). A hazard assessment of the encroachments was performed using established criteria in the encroachment white paper (SAFCA, 2016). None of the encroachments were considered to be high-risk, as determined by MBK in 2016.

During this due diligence review, encroachment data was verified, and a field investigation was conducted in April and June 2024. The total number of encroachments for this levee system is 119, which does not include any penetrations or associated structures, floodwalls, retaining walls, or closure structures. Work completed during this process is consistent with previous evaluation methodology.

No high-risk encroachments that would fall within the 1A, 1B, or 2 categories outlined in Section 2.2.4 were found, and no further engineering evaluations were required that would alter the risk assessment findings provided previously (Mead & Hunt, Inc., 2015). MBK has determined that there are no high-hazard encroachments that would preclude ULDC/FEMA certification, but an encroachment remediation plan to be prepared by MBK will address non-compliant and non-permitted encroachments.

In summary, there are no high-risk encroachments along the RALS. Mead & Hunt has confirmed with MBK that the RALS is in compliance with ULDC Section 7.12 criteria for encroachments and FEMA 44 CFR 65.10(d) for levee maintenance.

7 This section discusses the purpose, criteria, methodology, and results of penetration-specific requirements under ULDC and FEMA that were completed during this due diligence review.

3.1 Purpose
The purpose of the levee penetrations evaluation we conducted as part of this effort, was to assess the current conditions (based on new design water surface elevation data, updated documentation, and current conditions) and modifications to existing levee penetrations since previous analyses were conducted and reported in 2015, for compliance with ULDC and FEMA criteria.

3.2 Criteria
The ULDC, 7.13 provides criteria for assessment of existing penetrations for urban levee finding, which states that the “civil engineer needs to assess existing penetrations and render an opinion as to their impact on the reliable performance of the levee/floodwall for the full range of loading up to the hydraulic top of levee (HTOL).”

Further, FEMA 44 CFR 65.10(b)(2) provides criteria for assessment of closure structures . Gravity drain penetrations along the levee that provide hydraulic connectivity between the flooding source and the levee-impacted area are considered openings that require compliant closure structures. The FEMA criteria states: “All openings must be provided with closure devices that are structural parts of the system during operation and design according to sound engineering practices.”

The following evaluation criteria were identified for penetrations:
1) Structural strength – Pipes designed to be adequate to withstand loads of overlying fill or stresses applied by traffic. Earth loads are to be determined as outlined in EM 1110 -2-2902. 2) Joint flexibility – Joints should be flexible enough to adjust under expected settlement and stretching of pipe.
3) Emergency closure – Pipes open to the waterway must have provisions for emergency closure in the event of inoperative flap valves on the riverside end. 4) Condition of the pipeline – Pipes are required to be in good condition. Currently, no explicit guidance exists for the condition assessment of pipelines. In accordance with the ULDC, the exposed portions of pipe and culvert penetrations need to be visually inspected at least annually.

At minimum 5-year intervals, the interiors of all pipes and culvert penetrations need to be visually inspected and/or pressure tested. Alternatively, corrosion assessment can be completed using nondestructive means such as ultrasonic or electrical conductivity measurements. EM 1110-2- 2902 has been updated since the previous assessment to provide guidance for inspections and condition assessments, and prioritizing mitigation plans.

Items 1) and 2) were evaluated as part of the penetration analysis, while items 3) and 4) were evaluated as part of the condition assessment process.

8 3.3 Methodology
A phased approach was adopted for the penetration analysis, which is described in detail in our previous efforts (Mead & Hunt, Inc., 2015). Screening for potential high-hazard penetrations was conducted, and penetrations flagged during the screening were subjected to a full engineering evaluation to make a final determination of acceptability based on risk. The additional engineering evaluation of penetrations for the RALS is described in Appendix A of this report. Additionally, a technical memorandum (TM) has been prepared and is included in Appendix B to discuss exceptions for penetrations in the RALS and the respective work plans for addressing these exceptions. As part of this current due diligence review, there were no modifications to the previous methodology described in the documents referenced in this section.

Due to the voluminous nature of this material, that information was not reproduced here.

3.4 Results
During this due diligence review, 50 penetrations were reviewed, screened, and analyzed, as appropriate and the database was updated based upon previous methodology. Of these penetrations, the 16 gravity drain penetrations that provide hydraulic connectivity between the flooding source and the levee -impacted area were found to have compliant closure structures. A map summary and table summary of the penetrations and associated structures are included in this report as Exhibits 2B and 3B, respectively.

That analysis was completed during this due diligence review. Additional supporting documentation used for screening and analysis is provided in Appendix E.

For penetrations within the RALS that were determined (during the screening process) to require a full engineering evaluation to make a final determination of acceptability based on risk, their evaluation is summarized in Appendix A of this report. After evaluation, if an exception to ULDC is required for any of the above-referenced criteria, that risk assessment and any work plan are discussed in the TM in Appendix B.

3.5 Due Diligence Review; ULDC and FEMA Compliance
Mead & Hunt has updated the database, verified existing information, screened and flagged penetrations requiring engineering evaluation, and completed those additional evaluations. The evaluation includes some exceptions to ULDC based upon corresponding risk considerations and work plan development for certain exceptions.

Mead & Hunt has determined that the RALS compliance with ULDC Section 7.13 and FEMA 44 CFR

65.10(b)(2) criteria for penetrations is acceptable with the exceptions discussed in Appendix B and has concluded that there are no anticipated impacts to the reliability of the RALS’s performance during its full range of loading to the HTOL.

9 4.1 Purpose
The purpose of the evaluation conducted as part of this effort was to assess the existing levee floodwalls, retaining walls, and closure structures for compliance with ULDC and FEMA criteria. The as-built drawings of the floodwalls and closure structures within the RALS are provided in Appendix E, and a summary map and summary table of the floodwalls, retaining walls, and closure structures are shown in Exhibits 2C and 3C, respectively.

4.2 Criteria
The floodwall, retaining wall, and closure structure strength and stability analysis was based on the same criteria used in our previous certification report (Mead & Hunt, Inc., 2015). Criteria for floodwalls and other hydraulic retaining walls is outlined in EM 1110-2-2502. The following ULDC Section 7.14 criteria was considered for the referenced closure structures:

Current USACE design guidance for special features such as floodwalls, retaining walls, and closure structures is to be followed. This information is included in EM 1110-2-1913, EM 1110-2- 2502, EC 1110-2-6067, and ETL 1110-2-5711. Because design considerations for floodwalls are still evolving since the 2005 New Orleans flood, caution should be used when designing and assessing these structures. All global slope stability and embankment through -seepage and underseepage safety criteria requirements are applicable for floodwalls, retaining walls, and closure structures on levees. In addition, the civil engineer must evaluate and address the potential for the floodwall to induce settlement in the levee.

For closure structures, the civil engineer needs to provide the following information: maintaining entity, levee mile, Global Positioning System coordinates, Board permit number (if applicable)2, structure details, length of time to close structure, location, and type of materials for closure, structure dimensions, age, and performance history.

Closure structures need to be tested at least once a year before the flood season so that crews responsible for implementing the structures are familiar with their operation and to provide assurance that all parts are present and in working order.

FEMA 44 CFR 65.10(b)(2) provides criteria for assessment of the UPRR stoplog closure structure s in the Robla Creek South Levee and Arcade Creek North Levee as these facilities provide hydraulic connectivity between the flooding source and the levee impacted area. The FEMA criteria states: “All openings must

1 The EC and ETL have expired and the EM 1110-2-2502, Floodwalls and other Hydraulic Retaining Structures, has been updated since the ULDC publication.
2 The UPRR stoplog closures in the Robla Creek South Levee and Arcade Creek North Levee were original constructed under CVFPB permits 14477 and 14479 respectively, and modifications were implemented under permits 16032 and 16033-A.

10 be provided with closure devices that are structural parts of the system during operation and design according to sound engineering practices.”

4.3 Methodology
The floodwall, retaining wall, and closure structure analysis followed the same methodology used in our previous certification report (Mead & Hunt, Inc., 2015). Original designs or as-built drawings were obtained from SAFCA, facility owners, and site investigations. Updated plans were provided to Mead & Hunt and reviewed/incorporated.

The on-site condition assessment for each floodwall, retaining wall and closure structure facility was completed separately. The UPRR stoplog structures also include removable components that are stored in the City’s North Area service yard at 918 Del Paso Road. Visual inspection of materials was conducted, and the City inventoried the materials. The trial operation of each closure structure by City was observed by Mead & Hunt.

Retaining walls within the zone of influence of the levees were identified through field investigations and drawing reviews. The initial screening indicated that undrained reinforced concrete retaining walls three (3) feet or less in retained height and in sound condition do not create a significant risk to levee stability.

Landside retaining walls beyond 10 feet from the projected toe of the levee slope were excluded from structural stability analysis unless determined to influence the stability of the maintenance zone at the landside toe of the levee.

4.4 Results
As part of this due diligence review, Mead & Hunt reviewed previous information and as -builts, as well as modified plans for the RALS floodwalls, closure structures, and retaining walls as part of our analysis. For our condition assessments of floodwalls, closure structures, and retaining walls, a visual inspection (field investigation) took place in April 2024. The trial installations of the two (2) closure structure installations in the RALS have been overseen by Mead & Hunt (in accordance with the agreed upon City of Sacramento trial closure schedule), and no significant issues were found.

Exhibits 2B and 3C locate and identify the seven (7) floodwall reaches in the RALS. No floodwall modifications have been made to the RALS floodwalls since the original installations. The details for floodwall construction are included in drawing sets for the applicable levee reach included in Appendix E.

Two stoplog-type closure structures are located within the RALS at UPRR crossings:
• Arcade Creek North Levee UPRR crossing stoplog structure • Robla Creek South Levee UPRR crossing stoplog structure

The structures consist of reinforced concrete headwalls and sills with removable aluminum stoplogs and steel I-beam supports. The structures were originally constructed in 1986 by the City of Sacramento and later raised, strengthened, and modified under SAFCA’s levee improvements in 1995 and 1996. The details for closure structure construction are included in the drawing sets for the applicable levee reaches

11 enclosed in Appendices E6, E8, and E14. The Arcade Creek North Levee UPRR closure was found to have a grade beam extending from the top of rail, through the railroad ballast and 3-feet into the railroad bed providing an effective cutoff. The Robla Creek South Levee UPRR closure was found to have a grade beam extending 4 feet deep into the railroad bed, but the grade beam does not extend through the railroad ballast for the width of the railroad ties. The sill for the stoplog support is constructed using 10- foot-long precast concrete planks resting on the rail ties. A potential seepage window exists between the bottom of the sill planks and the top of the grade beam. However, the potential seepage through the railroad ballast was judged to not create a stability risk due to limited seepage velocity that would not mobilize the rock ballast. Limited modifications to these stoplog closures have recently been constructed, and the drawing set is included in Appendix E4.

The closure structures are operated and maintained by the City of Sacramento Department of Public Works. Trial closures are conducted once every five years (instead of annually). The recent trial closure report for the stoplog structures is included in Appendix E5. An exception TM for annual trial installation for these closure structures is included in Appendix C.

A total of 8 retaining walls were identified within the zone of influence of the RALS levees. Two (2) retaining walls on private properties identified in prior assessments have been removed through encroachment remediation efforts. Seven (7) retaining walls were previously identified as requiring structural evaluation, all within the City/County pump stations at:
• City Sump 140 at the landside toe
• City Sumo 157 (3 sections) at the waterside edge of levee crown • City Sump 158 (3 sections) at the landside toe.

The one (1) remaining retaining wall is a privately constructed concrete block wall at the landside toe of the Arcade Creek North Levee Station 5081+00, at 1026 Rivera Drive, previously found to be structurally insignificant due to minimal retained height.

4.4.1 Analysis Results
No additional analyses were required for the RALS floodwalls, closure structures, and retaining walls. The revised plans for the closure structures were reviewed and found to be in compliance with the standards and guidance for closure structures as indicated in this report and during previous efforts (Mead & Hunt, Inc., 2015).

4.4.2 Condition Assessment Results
The Robla Creek South Levee and Arcade Creek North Levee floodwalls were field inspected in April 2024 and found to be well-maintained and in serviceable condition for their intended use.

The retaining walls were also field inspected in December 2023, and each location was found to be unaltered. The walls requiring structural evaluation were found to be well -maintained and in serviceable condition for their intended use.

The two (2) closure structures (UPRR stoplog structures at the Robla Creek South Levee and Arcade Creek North Levee) were field inspected and found to be acceptable for the intended use

12 as documented in (Mead & Hunt, Inc., 2015). The operations are guided by the City’s Emergency Response Plan (ERP), Chapter 7, a copy of which is included in Appendix 8 of our previous certification report (Mead & Hunt, Inc., 2015). The plan outlines the following: a) Flood Procedures; b) Floodgate Locations; c) Materials Required for Floodgate Closure; d) Floodgate Threshold Elevations; and e) an outline of the Annual Flood Preparedness Plan and Procedures.

Multiple trial closures were witnessed by Mead & Hunt with the latest in 2021. During the February 2019 flood event, an emergency closure was necessary, and Mead & Hunt inspected the completed facility. The TMs documenting the trial closures are included in Appendix E5. The City has scheduled trial installations for the UPRR stoplog locations on a 5-year basis to minimize impacts upon critical railroad operations. Each fall, the items for stoplog closures (identified in the ERP) are inventoried and inspected. Mead & Hunt has determined that the set 5-year cycle, as opposed to an annual testing cycle, is acceptable, due to the City’s preparedness and training, but requires an exception to the ULDC.

4.5 Due Diligence Review; ULDC and FEMA Compliance
Mead & Hunt has determined that the RALS is in compliance with ULDC Section 7.14 and FEMA 44 CFR

65.10(b)(2) criteria for floodwalls, retaining walls, and closure structures, with the exception of the operation/installation cycle of the UPRR stoplog gates. These UPRR stoplog closure structures are both in good working order, and there are no anticipated impacts on the reliability of the RALS’s performance during its full range of loading to the HTOL.

Due to the logistics of closing the UPRR for trial closures, the City’s extensive preparedness, and the success of recent improvements and trial closures, Mead & Hunt has recommended that the UPRR trial closures be conducted on not more than a 5-year cycle, which requires an exception to the ULDC Section

7.14 and FEMA 44 CFR 65.10(c)(1)(iii) required annual testing cycle. The justification for this exception is included in this report as Appendix C.

13 5.1 Scope of Analysis
Because the updated analysis criteria and methodology for the wind setup and wave runup analysis is voluminous, it is fully contained in Appendix D and not reproduced here, only summarized.

ULDC 7.17 requires a wind-wave analysis. The wind setup and wave runup distances must be computed and added to the median 200-year still water surface elevation, and the resultant shall be no more than the required minimum top of levee (MTOL). Additionally, wind setup and wave runup must also be computed to support the analysis of erosion and overtopping impacts.

The formation and magnitude of wind-generated waves against shoreline structures are controlled by the physical conditions present on and near the shore, such as slope and roughness of the structure, wind speed, and distance over which wind blows (fetch length). Evaluations documented the Wind Wave Analysis and determined the wind setup and the runup for the 2 percent exceedance wave (wave runup which is exceeded by 2 percent of waves on average). The analyses were performed at the location on the levees expected to generate the largest wind setup and wave runup.

5.2 Results
Wind and wave analysis for the RALS was completed in 2015 and updated in 2024, in accordance with the requirements of ULDC 7.17. The Automated Coastal Engineering System (ACES) model, which is based on the U.S. Army Coastal Engineering Research Center’s Shore Protection Manual, was the primary tool for calculating wind setup and wave runup. Design wind speed with a return period of 72.6 years and a duration of two (2) minutes was used, in accordance with ULDC 7.17. Results in Appendix D indicate that the maximum combined wind setup and wave runup is 3.0 feet or less. The effects of wind setup and wave runup on the MTOL and erosion are found in MBK’s Engineer’s Report, sections for ULDC 7.2 and ULDC 7.10, respectively.

5.3 Due Diligence Review and ULDC Compliance
Mead & Hunt has updated the previous wind setup and wave runup analysis for the RALS utilizing the most applicable and current data available for wind speed, terrain, and water surface elevation, as shown in Appendix D. Mead & Hunt has determined that the RALS is in compliance with ULDC Section 7.17 criteria for wind setup and wave runup.

14 6.1 Purpose
The purpose of the O&M Manual review was to ensure existing O&M manuals comply with ULDC and FEMA requirements and provide any additional reviews needed for elements not previously included.

This current effort does not trigger any additional USACE-approved O&M manual reviews.

Levees in the study area are maintained by ARFCD, but the governing O&M manuals are those developed by USACE. The updated Unit No. 118 – Part No. 2 supplement to the standard O&M manual for the Sacramento River Flood Control Project was issued on January 28, 2023. The update addressed revisions to address the details of the most recent levee remediation contracts.

The review of the closure structure operations by the City of Sacramento is summarized in Section 4.

The City of Sacramento maintains equipment operation and maintenance manuals at each pump station .

Mead & Hunt also compiled the pump operational data and setpoints for the drainage pump stations in RALS for review.

6.2 Criteria
ULDC requires that levee systems must have an O&M manual consistent with USACE requirements. All facilities providing the necessary urban level of flood protection must be operated and maintained by an identified public agency. Where the levee system has more than one agency with O&M responsibilities, they are required to coordinate efforts. FEMA 44 CFR 65.10(c) provides criteria for operations plans, and part (d) provides criteria for levee system maintenance plans.

6.3 Results
The O&M manuals and operating procedures were found to cover all system components ; the levee system, closure structures, and the pump stations. Each of these three components is operated by different public agencies with the authority and resources to do so. As there is little overlap in O&M between these entities, minimal coordination is necessary; however, each entity was found to understand its role in system operation.

The O&M manual and operating procedures for the pump stations were reviewed with the City and found to accurately represent the facility operations and maintenance needs.

6.4 Due Diligence Review and ULDC Compliance
Mead & Hunt has determined that the RALS is in compliance with ULDC Section 7.20 criteria for O&M manuals, as well as FEMA 44 CFR 65.10 (c) for operation plans for closure structures and pump stations and 65.10(d) for levee system maintenance plans.

15 Based on our due diligence activities on the RALS, Mead & Hunt has concluded that the overall condition of the RALS has not significantly changed since the ULDC and FEMA certification efforts documented in (Mead & Hunt, Inc., 2015). It is our professional opinion that RALS meets ULDC requirements for Sections 7.12, 7.13, 7.14, 7.17, and 7.20 for Encroachments, Penetrations, Floodwalls, Retaining Walls, and Closure Structures, Wind Setup and Wave Runup, and O&M Manuals, respectively – pending mitigation plan items discussed in the penetration work plan TM in Appendix B. It is also our professional opinion that RALS meets FEMA criteria in accordance with 44 CFR 65.10(b)(2) for the gravity drain penetrations, and the UPRR stoplog closure structures. Other conclusions and recommendations pertaining to the RALS are discussed below.

16 7.2 Recommendations
Below is a list of Mead & Hunt’s recommendations for the RALS. 1) The encroachments, penetrations, floodwalls, retaining walls, and closure structures either discussed in this report or previously reported (Mead & Hunt, Inc., 2015) in the RALS should continue to be maintained and kept in good operating condition, monitored, and inspected per ULDC requirements and applicable O&M manuals.
2) Aging infrastructure, especially penetrations, should be routinely evaluated for condition assessment based on future inspections. The local maintaining agency should coordinate with owners of encroachments to replace and update as required to maintain the performance of the RALS with assistance from the CVFPB, if necessary.
3) The mitigation plans for ULDC exceptions, described in Appendix B, should be carried out.

SAFCA should request monthly updates on the status of the resolution with the responsible parties.
4) The UPRR stoplog closures should continue to be trial-operated on a 5-year cycle with annual preparedness conducted in the fall.
5) The RALS should continue to be operated and maintained in accordance with the approved O&M manuals.

7.3 Limitations
Mead & Hunt’s services were performed in a manner consistent with the degree of skill and care ordinarily exercised by members of the profession currently practicing in the same locality under similar conditions.

No other warranty, expressed or implied, is made by the completion of the work supporting this ULDC/FEMA Due Diligence Report. Our professional services were limited to supporting engineering opinions needed to address ULDC criteria for encroachments, penetrations, floodwalls and closure structures, wind setup and wave runup, and O&M manuals.

Our conclusions regarding the condition and safety of the RALS, related facilities, and their conformance to ULDC criteria are not stated as a guarantee but they do represent our best professional judgment. This judgment must be recognized as affected to a certain degree by the practical limitations that affect all evaluations of constructed water-retention structures, relative principally to the approximate knowledge of the condition and properties of the foundation materials and existing structures.

The conclusions we present in this ULDC/FEMA Due Diligence Report are based in part upon the data obtained from limited correspondence, reports, surveys, instrumentation, testing, and surface visual observations. Actual conditions may escape detection by reporting, surveying, monitoring, testing, and visual inspection/observation and may be unknowingly different from the conditions described in this report. The nature and extent of such variations may not become evident until the levees experience high water conditions or when further tests and evaluations are performed. If variations from the described conditions are encountered, additional investigations and assessments of the levee condition and performance may need to be conducted. It may be necessary to revise the conclusions and recommendations described herein, and/or undertake additional remediation measures.

17 All conclusions and recommendations are based on the data and limitations described above, but they are also based on this specific snapshot in time, assuming that proper inspection, maintenance, repair, and replacement by utility owners and enforcement of the condition requirements of the permits by the CVFPB. Special attention should be paid to documenting the performance and condition of penetrations that are anticipated to be at the end of their useful life.
