COUNTY OF SACRAMENTO AND CITY OF

SACRAMENTO

RECOMMENDED RIGHT-OF-WAY PLAN TO
COMPLY WITH ULDC CRITERIA 7.11

AMERICAN RIVER NORTH LEVEE SYSTEM
SEPTEMBER 2024

FRAMEWORK FOR ADDRESSING RIGHT-OF-WAY CONFLICTS
This plan is prepared by MBK Engineers, the certifying engineer for the American River North Urban Levee Design Criteria (ULDC) Engineering Evaluation, under contract by the Sacramento Area Flood Control Agency (SAFCA). The American River North Levee System does not meet ULDC Right-of-Way (ROW) Criteria 7.11. As such, the Engineer’s Evaluation is requiring that the City of Sacramento and the County of Sacramento (City and County) prepare a ROW Implementation Plan to occur at least 1-year from adoption of the American River North Levee System’s Urban Levee Design Criteria Engineer’s Report or by October 2025, to be shared with SAFCA and the American River Flood Control District (ARFCD).

This report summarizes the evaluation rationale and recommendations for the City and County to incorporate into the ROW Implementation Plan in order to comply with ULDC Criteria 7.11.

Right-of-Way data has been collected on existing, recorded, easements and fee title ownership status.

Current topographic survey data and landside and waterside levee toe alignments have also been gathered. To confirm easements, levee toe approximation, and offset distances, the attached ROW maps include the ULDC ROW criteria as offset lines. This was done in order to perform a visual evaluation of available property or easement for operations and maintenance (O&M), flood fighting, and future improvements.

A preliminary evaluation of available ROW information is provided that identifies where ROW criteria is not met. Summary tables include properties where a 20-foot landside zone for visibility is available; properties where a 10-foot landside clear distance for access is available; and remaining properties, American River North Levee System September 30, 2024
Right-of-Way Plan Recommendations Page 2
which do not meet either the 10-foot landside clear distance or the 20-foot landside zone. The deficiencies are compared to other conflicts found during the review of encroachments, penetrations, and O&M activities.

The identified conflicts are the basis of the ROW Plan. These recommendations focus on two categories of non-compliant properties, based on their impacts to ROW:
 Property boundaries or easements less than 10-feet from the landside or waterside levee toes would be considered first priority.
 Locations where 10-to-20-feet of property or easement is present, is considered second priority.

Conflicts with encroachments and O&M activities will fall into one of these categories based on severity of impact. For the second priority ROW conflicts, visibility is one of the criteria; thus, review of fences in these areas was a part of the review and planning process. These priorities have been identified in the Summary Section, and are intended to provide the City and County with the steps needed to meet ROW, including an estimated timeline to reach these goals.

BACKGROUND
The ULDC requires urban and urbanizing areas to allow adequate room for maintenance, inspection, patrols during high water events, and for flood-fighting; allow additional room to expand facilities in the future; and prohibit excavations and land modifications that would endanger the integrity of the flood protection system.

More specifically, the ULDC requires fee title or an easement for the entire levee prism extending to a minimum of 20-feet beyond the landside toe of the flood protection system for access and inspection.

Where adjacent lands are developed or developing, and the minimum 20-feet cannot be acquired, alternatives to obtaining the landward 20-feet in fee or easement include:
 Obtaining a minimum 10-foot-wide landside access zone through fee, or  Obtaining an easement and/or securing visibility for the 20-foot zone landward of the levee toe.

Furthermore, waterward of the levee prism where there is sufficient area to do so without resulting in the loss of sensitive riparian habitat, consideration should be given to acquiring a 15-foot-wide zone for inspection and maintenance. Please refer to the following cross section (Figure 1).

American River North Levee System September 30, 2024
Right-of-Way Plan Recommendations Page 3
Figure 1. Right-of-Way Cross Section
In addition to the minimums required by the ULDC for access and inspection, the ULDC recommends acquiring right-of-way that has a width equal to at least four times the levee height or 50-feet, whichever is greater, on the landside of the 20-foot clear zone for longer-term flood protection. Lastly, the ULDC recommends that the City or County adopt restrictions on excavations within 200-feet to 400- feet depending on the levee height.

Prior to the publication of the ULDC in 2012, SAFCA commenced a levee improvement program with the goal of providing a 200-year level of flood protection. Most of the levees are located within urban areas with dense residential development within 20-feet of the landside levee toe. As the program has progressed, SAFCA strived to acquire 20-feet from both the landside and waterside toes wherever possible. The American River North Levee System includes the Arcade Creek South Levee, the Natomas East Main Drainage Canal East Levee, and the American River North Levee. In general, a majority of the American River North Levee System does not have a minimum of 20-feet in fee-title or easement.

Despite not having fee-title or easement, the entire levee system meets ULDC for right-of-way through a reduced landside corridor and/or 20-foot “free and clear” zone. Each of the locations lacking 20-feet in fee-title or easement are discussed below.

The attached right-of-way maps depict the lands and ownership status as of August 2024. Minor road crossings are not highlighted, as these rights are owned by the City or County. Levee operation and maintenance of the American River North Levee System is performed by the American River Flood Control District (ARFCD).

ARFCD provides an annual mailing notice prior to the flood season to alert the residents immediately adjacent to the levee toe of the importance of preserving the levee easement and to provide a reminder to contact the District if they see any problems with the levee. Additionally, ARFCD mails a yearly newsletter to all homes protected by the levees. This newsletter discusses topics such as the purpose American River North Levee System September 30, 2024
Right-of-Way Plan Recommendations Page 4
and role of the District, current and upcoming projects, being flood aware, the importance of flood insurance, and to be aware of District equipment and patrols during the flood season.

APPLICABLE LAND USE CODES
The applicable land use agency codes that cover ULDC requirements are provided below.

From the Sacramento 2040 General Plan, adopted by City Council on February 27, 2024:
 ERC-6.6 Flood Regulations. The City shall continue to regulate new development in accordance with State requirements for 200-year level of protection and federal requirements for 100-year level of protection.
 ERC-6.10 Levee Setbacks for New Development. The City shall require adequate setbacks from flood control levees and prohibit new development from using levees as a primary access point, consistent with local, regional, State, and federal design and management standards.  ERC-6.11 Unobstructed Access to Levees. The City shall provide unobstructed access, whenever feasible, on City-owned land adjacent to levees for maintenance and emergencies.

From the Sacramento County General Plan of 2005 – 2030, adopted by the Sacramento County Board of Supervisors on November 9, 2011, as amended:

Land-Use Element, Amended December 13, 2022 – this reflects the 100-year floodplain.

Sacramento County Zoning Code, adopted by the Sacramento County Board of Supervisors, February 2024.
 4.2.3.E 200-year Floodplain. The area adjoining a river, stream, or water course which is subject to inundation by the 200-year flood.
 4.25. Development Standards for Property Adjacent to Designated Tributaries. No building or structure shall be erected or maintained within the 100-year floodplain, or within the 200-year floodplain in areas subject to the Urban Level of Flood Protection, of designated tributaries, as defined in Section 4.2.3, and no lot shall be created unless the standards and requirements set forth in this Section are complied with and maintained. The locations of “designated tributaries indicated on the Comprehensive Zoning Plan are approximate. Therefore, in order to ensure compliance with the provisions of this Section, the proponent of any application for entitlement on any property located within 200 feet of the center line of a designated tributary must demonstrate the applicability of development standards set forth in this Section.  4.7.3.A Development Standards. No building or structure other than an accessory building is located closer than 35 feet, and no accessory building is located closer than 25-feet to the landward toe of the levee.

FINDINGS
Following are the findings from this data review and basis for the needed ROW recommendations for each of the three levee segments: Arcade Creek South Levee; Natomas East Main Drainage Canal East Levee and the American River North Levee.

American River North Levee System September 30, 2024
Right-of-Way Plan Recommendations Page 5

ARCADE CREEK SOUTH LEVEE
Arcade Creek South Levee Station 4000+00 to 4001+30 (Within City of Sacramento) A railroad embankment with active tracks crosses through the levee at the downstream end. This embankment creates an oversized levee. The railroad owns the land below the tracks at this crossing location extending 100-feet on either side of the tracks. A Sacramento-San Juaquin Drainage District (SSJDD) easement is present below the levee footprint, extending from 50-feet landward of the levee toe to the waterside levee toe. This corridor is kept clear of woody vegetation and obstructions allowing ARFCD to inspect for problems. On occasion, ARFCD will request that the railroad perform specific maintenance actions or will request permission to perform specific maintenance actions. This cooperation has been successful. Railroad easements already restrict development creating a clear space at the toe of the levee. There is sufficient open space at the toe of the levee; therefore, there is no intent to acquire fee-title or easement from the Railroad.

Arcade Creek South Levee Station 4001+30 to 4007+00 (Within City of Sacramento) From approximately Station 4002+20 to 4007+00 the landside toe ROW is less than 20-feet, but a minimum of approximately 10-feet. A SSJDD Easement exists under the levee footprint extending approximately 10-feet landward of the levee and extending to the channel centerline. Residential lots have established fences at the edge of this 10-foot easement.

ARFCD should monitor the landside corridor to ensure access and visibility and continue to foster a cooperative relationship with the landowner. There is no intent to acquire additional rights-of-way for this reach.

Arcade Creek South Levee Station 4007+00 to 4031+50 (Within City of Sacramento) From approximately Station 4007+00 to 4031+50, the landside toe ROW is approximately 20-feet.

Residential lots have established fences at the edge of this 20-foot easement.

Arcade Creek South Levee Station 4031+50 to 4034+80 (Within City of Sacramento) From approximately Station 4031+50 to 4034+80, the landside toe ROW is less than 20-feet, but a minimum of approximately 10-feet. A SSJDD Easement exists under the levee footprint extending approximately 10-feet landward of the levee and extending to the channel centerline. Residential lots have established fences at the edge of this 10-foot easement.

Arcade Creek South Levee Station 4034+80 to 4035+50 (Within City of Sacramento) American River North Levee System September 30, 2024
Right-of-Way Plan Recommendations Page 6
Norwood Avenue crosses the levee at this location. By its purpose, the corridor provides sufficient access and visibility. Potential issues at this location are handled by ARFCD in cooperation with the City of Sacramento. There is no intent to acquire additional rights-of-way.

Arcade Creek South Levee Station 4035+50 to 4047+50 (Within City of Sacramento) From approximately Station 4035+50 to 4047+50, the landside toe ROW is less than 20-feet, but a minimum of approximately 10 feet. A SSJDD Easement exists under the levee footprint extending approximately 10-feet landward of the levee and extending to the channel centerline. Residential lots have established fences at the edge of this 10-foot easement. ARFCD should monitor the landside corridor to ensure access and visibility and continue to foster a cooperative relationship with the landowner. There is no intent to acquire additional rights-of-way for this reach.

Arcade Creek South Levee Station 4047+50 to 4052+00 (Within City of Sacramento) This reach presents the greatest access and visibility challenges for ARFCD. The levee and waterside and landside toe corridors are not entirely owned or encumbered by SSJDD. A SSJDD Easement exists under the levee footprint to the channel centerline. Residential lots have established fences at the toe of the levee embankment which limits access along the landside toe of the levee. The levee can be maintained and inspected from the crown of the levee. Residents in the homes at the toe of the levee assist in inspecting for seepage and boils which would indicate excessive underseepage.

In an emergency, flood fight access can be obtained to the landside of the levee through public roads and access into backyards.

In accordance with the Sacramento General Plan 2040, ERC-6.10 Levee Setbacks for New Development and to meet the minimum requirements by ULDC for access and inspection, the City shall acquire the necessary easement on the landside of levee toe for the 20-foot clear zone along the vacant lots C-4, C-5, C-6, C-7 and C-8 owned by Twin Rivers Unified School District. Related to these lots, the City should enter into an agreement to allow ARFCD the opportunity to store flood fight equipment and access to the levee. Additionally, fee-title or easement should be pursued as a future effort for the other residential lots within this levee segment.

Arcade Creek South Levee Station 4052+00 to 4063+50 (Within City of Sacramento) From approximately Station 4052+00 to 4063+50, the landside toe ROW is less than 20-feet, but a minimum of approximately 10-feet. A SSJDD Easement exists under the levee footprint extending approximately 10-feet landward of the levee and extending to the channel centerline. Residential lots have established fences at the edge of this 10-foot easement.

Arcade Creek South Levee Station 4063+50 to 4064+50 (Within City of Sacramento) The City of Sacramento Bike Trail bridge crosses the levee at this location. By its purpose, the corridor provides sufficient access and visibility. Potential issues at this location are handled by ARFCD in cooperation with the City of Sacramento. There is no intent to acquire additional rights-of-way.

Arcade Creek South Levee Station 4064+50 to 4067+50 (Within City of Sacramento) American River North Levee System September 30, 2024
Right-of-Way Plan Recommendations Page 7
The levee and waterside and landside toe corridors are not entirely owned or encumbered by SSJDD. A SSJDD Easement exists under the levee footprint to the channel centerline and ingress/egress easement to allow for access, right to construct, and maintain. The landside toe ROW is less than 20-feet and is approximately less than 5-feet. Residential lots have established fences at the toe of the levee embankment, on their respective property lines, which limits access along the landside toe of the levee.

The levee can be maintained and inspected from the crown of the levee. Residents in the homes at the toe of the levee assist in inspecting for seepage and boils which would indicate excessive underseepage.

In an emergency, flood fight access can be obtained to the landside of the levee through public roads and access into backyards.

The landowners of the landside toe corridors have allowed access to ARFCD. However, fee-title or easement should be pursued as a future effort. Until such time, ARFCD should monitor the landside corridor to ensure access and visibility and continue to foster a cooperative relationship with the landowners.

Arcade Creek South Levee Station 4067+50 to 4069+50 (Within City of Sacramento) Rio Linda Boulevard crosses the levee at this location. By its purpose, the roadway provides sufficient access and visibility. Additionally, SAFCA owns the property immediately upstream of the bridge.

Potential issues at this location are handled by ARFCD in cooperation with the City of Sacramento. There is no intent to acquire additional rights-of-way.

Arcade Creek South Levee Station 4069+50 to 4110+00 (Within City of Sacramento) This reach presents the greatest access and visibility challenges for ARFCD. The levee and waterside and landside toe corridors are not entirely owned or encumbered by the SSJDD. A SSJDD easement exists under the levee footprint to the channel centerline. The landside toe ROW is less than 20-feet and is approximately less than 5-feet. Residential lots have established fences at the toe of the levee embankment, on their respective property line, which limits access along the landside toe of the levee.

The hydrograph in this reach mimics one of a minor stream in that the high-water events have a sharp hydrograph and do not remain elevated above flood stage for very long. Additionally, there is general visibility into these backyards, the levee is relatively short and flood fighting can be accessed from the levee crest. The levee can be maintained and inspected from the crown of the levee.

In an emergency, flood fight access can be obtained to the landside of the levee through public roads and access into backyards.

The landowners of the landside toe corridors have allowed access to ARFCD. However, fee title or an easement should be pursued as a future effort. It should be noted, that in this reach the house foundations are in close proximity to the levee toe, as close as 10-feet in some locations. Therefore, acquiring the needed right-of-way would require taking the house. Priority would be given to acquiring easements on parcels located between Station 4069+50 and 4100+00.

Related to Diamond Estates, A-20 and the vacant lots A-21 and A-22, in accordance with the Sacramento General Plan 2040, ERC-6.10 Levee Setbacks for New Development and to meet the minimum requirements by ULDC for access and inspection, the City should place an easement on the landside of levee toe for the 20-foot clear zone. Until such time, ARFCD should monitor the landside corridor to American River North Levee System September 30, 2024
Right-of-Way Plan Recommendations Page 8
ensure access and visibility and continue to foster a cooperative relationship with the landowners. It should be noted, ARFCD and SAFCA have had multiple conversations with the property owner to include a 15-foot easement in the development plans. Language of this easement would include providing a “free and clear zone” and use of wrought iron fencing that allows visibility from the levee for inspection purposes.

NATOMAS EAST MAIN DRAINAGE CANAL EAST LEVEE
Natomas East Main Drainage Canal East Levee Station 2986+50 to 2995+00 (Within City of Sacramento)
From approximately Station 2986+50 to 2995+00, the landside toe ROW is less than 10-feet. A SSJDD Easement exists under the levee footprint extending into the channel. Commercial lots have established fences near the landside levee toe. The levee can be maintained and inspected from the crown of the levee.

SSJDD easement does not extend more than 5 feet beyond the landside toe within this levee segment.

In an emergency, flood fight access can be obtained to the landside of the levee through public roads and access into commercial property. For new development, the City should acquire fee-title to ensure that there is a 20-foot clear zone from the landside levee toe to meet the minimum requirements for visibility in accordance with the Sacramento General Plan 2040, ERC-6.10 Levee Setbacks for New Development and to meet the minimum requirements by ULDC for access and inspection. The City should acquire an easement on the landside of levee toe for the 20-foot clear zone.

Natomas East Main Drainage Canal East Levee Station 2995+00 to 3001+00 (Within City of Sacramento)
From approximately Station 2995+00 to 3001+00, the landside toe ROW is less than 20-feet. However, PG&E, City of Sacramento, and Railroad property run parallel, under, and adjacent to the levee for this levee segment. This corridor is kept clear of woody vegetation and obstructions allowing ARFCD to inspect for problems. Potential issues at these locations are handled by ARFCD in cooperation with the City of Sacramento. SSJDD easement does not extend to the landside toe within this levee segment. The landowners of the landside toe corridors have allowed access to ARFCD. However, the City should place an easement on city owned property in accordance with Sacramento General Plan 2040, ERC-6.11 Unobstructed Access to Levees, the City shall provide unobstructed access, whenever feasible, on Cityowned land adjacent to levees for maintenance and emergencies. Until such time, ARFCD should monitor the landside corridor to ensure access and visibility and continue to foster a cooperative relationship with the landowners. Additionally, the City should acquire an easement on the PG&E property landside of levee toe for the 20-foot clear zone.

Natomas East Main Drainage Canal East Levee Station 3001+00 to 3051+40 (Within City of Sacramento)
A railroad embankment with active tracks is present adjacent to this levee segment. This embankment creates an oversized levee. The railroad owns the land below the tracks at this crossing location extending 100-feet on either side of the tracks. This area can be used to flood fight. An SSJDD easement is present below the levee footprint extending from below the landside crest hinge-point to the waterside levee toe. The levee and waterside and landside toe corridors are not entirely owned or American River North Levee System September 30, 2024
Right-of-Way Plan Recommendations Page 9
encumbered by SSJDD. However, the Railroad ROW extends approximately 100-feet landward of the toe. This Railroad easement is secure and will likely not change or allow development within this 100- foot zone. Additionally, landward access to this Railroad easement may occur through City roadways.

In an emergency, flood fight access can be obtained to the landside of the levee through public roads into the Railroad easement and/or access into backyards.

This corridor is kept clear of woody vegetation and obstructions allowing ARFCD to inspect for problems.

On occasion, ARFCD will request the Railroad to perform specific maintenance actions or will request permission to perform specific maintenance actions and this cooperation has been successful. There is no intent to acquire fee-title or easement for Railroad lands.

Natomas East Main Drainage Canal East Levee Station 3003+00 to 3004+00 (Within City of Sacramento)
Arden Garden Connector crosses the levee at this location. By its purpose, the roadway provides sufficient access and visibility. Potential issues at this location are handled by ARFCD in cooperation with the City of Sacramento. There is no intent to acquire additional rights-of-way.

Natomas East Main Drainage Canal East Levee Station 3021+40 to 3022+00 (Within City of Sacramento)
El Camino Avenue crosses the levee at this location. By its purpose, the roadway provides sufficient access and visibility. Potential issues at this location are handled by ARFCD in cooperation with the City of Sacramento. There is no intent to acquire additional rights-of-way.

AMERICAN RIVER NORTH LEVEE
American River North Levee Station 3000+00 to 3009+00 (Within City of Sacramento) Commercial parking lot and development are present at the landside levee toe. The landside toe ROW is less than 20-feet and ranges between 0-feet and 10-feet. By their purposes the parking lot provide sufficient access and visibility. Potential issues at this location are handled by ARFCD in cooperation with the landowner. A SSJDD Easement exists under the levee footprint extending approximately 5-feet to 20-feet landward and up to 200-feet waterward of the levee or to the fence line.

As per the Sacramento General Plan 2040, ERC-6.11 Unobstructed Access to Levees, the City shall provide unobstructed access, whenever feasible, on City-owned land adjacent to levees for maintenance and emergencies. For new development, the City should acquire fee title to ensure that minimum requirements for visibility can be met in accordance with the Sacramento General Plan 2040, ERC-6.10 Levee Setbacks for New Development and to meet the minimum requirements by ULDC for access and inspection. The City should acquire an easement on the property landside of levee toe for the 20-foot clear zone.

American River North Levee Station 3009+00 to 3013+50 (Within City of Sacramento) Railroad Drive, owned by the City of Sacramento, is present and runs parallel to the landside levee toe.

The landside toe ROW is less than 20-feet and ranges between 0-feet and 10-feet. By the purpose of the road, sufficient access and visibility is present. Potential issues at this location are handled by ARFCD in cooperation with the City of Sacramento. A SSJDD Easement exists under the levee footprint extending American River North Levee System September 30, 2024
Right-of-Way Plan Recommendations Page 10
approximately 5-feet to 10-feet landward and up to 230 feet waterward of the levee or to the fence line or edge of pavement. As per the Sacramento General Plan 2040, ERC-6.11 Unobstructed Access to Levees, the City shall provide unobstructed access, whenever feasible, on city-owned land adjacent to levees for maintenance and emergencies. There is no intent to acquire additional rights-of-way.

American River North Levee Station 3013+50 to 3019+00 (Within City of Sacramento) Multiple transportation corridors pass through this levee segment and include Del Paso Boulevard underpass, UPRR crossing, State Highway 160 bridge. The landside toe ROW is difficult to assess, but likely has nearly 20-feet. Sufficient access and visibility are present. Potential issues at this location are handled by ARFCD in cooperation with the City of Sacramento, Caltrans, and the railroad. A SSJDD Easement exists under the levee footprint extending approximately 5-feet to 20-feet landward and waterward of the levee.

For new development, the City should acquire fee-title to ensure that there is a 20-foot clear zone from the landside levee toe to meet the minimum requirements for visibility in accordance with the Sacramento General Plan 2040, ERC-6.10 Levee Setbacks for New Development and to meet the minimum requirements by ULDC for access and inspection. There is no intent to acquire additional rights-of-way.

Reviewed by: Jeffrey Kashiwada, Senior Project Engineer Date: August 27, 2024
Subject: Penetration Exceptions Work Plan, American North Levee System (ANLS) SAFCA Due Diligence Review for Urban Levee Design Criteria Section 7.13 This Technical Memorandum (TM) 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) for the ANLS. This TM pertains to Section 7.13 – Penetrations.

The purpose of this TM is to provide background, justification, and work plans for exceptions to ULDC Section 7.13 requirements for penetrations. Mead & Hunt has identified penetrations, as summarized in our Engineering Evaluations TM, that require a work plan to resolve exceptions to ULDC criteria. Both this TM and the Penetrations Evaluation TM are attached as appendices to Mead & Hunt’s ULDC Due Diligence Report for the ANLS.

ULDC Section 7.13 criteria states:

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).

Mead & Hunt evaluated penetrations based on a compilation of requirements from the U.S. Army Corps of Engineers (USACE), Central Valley Flood Protection Board (CVFPB), ULDC, and FEMA which came down to four criteria – structural strength, joint flexibility, emergency closure, and condition of the penetration. The specific criteria used is outlined in our previous certification reviews in 2015. As part of the current due diligence effort, Mead & Hunt has re-screened penetrations for engineering evaluations and condition assessment factors. The specific factors that were considered in the Engineering Evaluations TM were: below design water surface elevation (DWSE); structural factors (depth, material, and diameter); age; joint flexibility; CVFPB permit status; and inspection completion/documentation within the last five (5) years. All evaluations were conducted in accordance with ULDC section 7.13.

Based upon our Penetrations Evaluation TM (referenced above), Mead & Hunt has developed work plans for those penetrations found to require an exception to ULDC Section 7.13 criteria. The categorical risk assessment reasoning for the exceptions and proposed work plans for each category are discussed below in Sections 2.1.1 through 2.1.6.

category, owner, and basic information is provided in Section 2.2.

2.1 Exceptions and Mitigation Plans
Mead & Hunt has screened and provided engineering evaluations for the following exception categories (Engineering Evaluations TM). For each exception category, there is a proposed work plan (if necessary).

2.1.1 Penetrations Below DWSE
Exception background and assessment: Our Penetrations Evaluation TM includes analysis and finding of no significant impact for all penetrations in this category.

Exception work plan: None required.

2.1.2 Mechanical Joint Flexibility Risk Factors
Exception background and assessment: None found.

Work plan: Not required.

2.1.3 Penetration Structural Evaluations
Exception background and assessment: Based upon initial screening of the need for structural evaluations in the ANLS, one (1) Sacramento Regional County Sanitation District (SRCSD) sewer pipe was flagged for evaluation. The pipe is SRCSD’s Dry Creek Interceptor crossing under Arcade Creek immediately downstream of the Sacramento Northern Bike Trail and is a 66- inch RCP with approximately 28 feet of cover, SAFCA ID 1050, AR01 Station 4063+71. The pipe materials for the identified crossing are strong, with high-class bedding and backfill, and not found to be at risk of failure. However, load calculations identified low factors of safety, using conservative assumptions for loading and strength. The penetrations identified are unlikely to pose a threat to levee integrity or reliability at a full range of loading (up to the HTOL), based upon over 40 years of satisfactory performance. Attachment 1 of this TM discusses this penetration in further detail, and Attachment 2 is a figure showing the location of the penetration.

Work plan: SAFCA (via Mead & Hunt) will work with SRCSD to obtain and review penetration information, including pipe classification, backfill methods, and data on installation at depth.

SRCSD will conduct pipe inspections to review for cracking and distress, after which assessment findings will be completed by Mead & Hunt, and supplements to this due diligence report will be issued within one (1) year of transmittal of the Final ULDC Engineer’s Report to the responsible land use agency (City of Sacramento). As required, details for any proposed repairs will be submitted to SAFCA, American River Flood Control District (ARFCD), CVFPB, and the responsible land use agency (City or County of Sacramento) for review. The responsible land use agency will ensure that such repairs will be completed within five (5) years of the Final ULDC Engineer’s Report.

Completion of the required work plan, which may include collection of documents, inspection, construction, and reporting, shall be evaluated and transmitted to the responsible land use agency and be appended to the ULDC Engineer’s Report. This supplemental information shall be retained and used for review by the land use agency during future ULDC evaluations.

2.1.4 Penetrations Exceeding Age Expectancy (Useful Life) Exception background and assessment: Based upon penetration material, anticipated useful life, and owner practices certain penetrations required further review as discussed in our Engineering Evaluations TM. Attachment 1 to this TM summarizes existing data on these penetrations, and Attachment 2 maps the location.

A total of 36 penetrations have been identified that have passed the minimum threshold Mead & Hunt has established for screening of remaining service life. It is recommended that these pipes be subject to additional inspection. Except as described herein, pipes that have been recently inspected and found to have remaining useful life are also included in the list. They are flagged for purposes of identifying those that require increased vigilance. The age limit established for screening of penetrations is described in our Engineering Evaluations TM and is based on pipe material.

Work plan: SAFCA (via Mead & Hunt) will identify penetrations requiring further assessment and notify the Owners of necessary inspections and reporting, requesting that any existing available inspection results be provided within sixty (60) days of the transmittal of the Final ULDC Engineer’s Report to the SAFCA and the responsible land use agency (City or County of Sacramento). Supplemental reporting to accompany this due diligence review will be completed by SAFCA (via Mead & Hunt) within one (1) year of the report date to document further findings and identify any additional work as needed.

SAFCA (via Mead & Hunt) will lead this outreach. The ARFCD, the CVFPB, and/or land use agencies (City and County of Sacramento) should continue to follow up with utility owners and require documentation of pipe conditions. . The responsible land use agency will be responsible for enforcement, along with the CVFPB, if responses from utility owners are delayed.

Based upon the findings, the utility owner may be required to develop a replacement plan, as determined necessary by the SAFCA and the land use agencies.

Utilities will be required to develop an inspection plan/schedule and/or a replacement plan within one (1) year of notification. All inspections shall be completed within two (2) years of notification.

Given the nature of the facilities with existing access limitations, alternative inspection methods may be required.

Any penetrations that are inspected and found to be potentially high hazard will be prioritized by SAFCA based on the level of risk and must be removed or modified and provided to the land use Technical Memorandum

agency for mitigation. All mitigation efforts must be implemented within five (5) years of the ULDC Engineer’s Report finalization. The removal or modification/permitting efforts must be completed by the penetration owner or as part of a CVFPB Enforcement Action. Non-high hazard penetrations that have exceeded their anticipated useful life should continue to be inspected every five (5) years (in compliance with ULDC section 7.13), and additional monitoring should be provided by the penetration owner. During these additional monitoring efforts, any performance issues should be reported to the appropriate land use agency as well as SAFCA, ARFCD, and the CVFPB.

Completion of the required work plan, which may include inspection, monitoring, construction, and reporting, shall be documented and transmitted to the responsible land use agency (City of Sacramento/Sacramento County) and appended to the ULDC Engineer’s Report. This supplemental information shall be retained and used for review by the land use agency during future ULDC evaluations.

2.1.5 No Associated CVFPB Permit
Exception background and assessment: In our Engineering Evaluations TM, we determined that the ANLS has four (4) penetrations for which no associated CVFPB permits were found.

These unpermitted penetrations are not inherently high-hazard penetrations; however, the lack of documentation and compliance with permitting standards require that specific analyses be conducted for each penetration to assess each individual penetration’s risk. Attachment 2 to this TM maps the location of the penetrations lacking permitting documentation.

The penetrations were identified through field investigation and review of plans, but no permits were identified. These penetrations are unlikely to pose a threat to levee integrity or reliability at a full range of loading up to the HTOL (based on available information). Three (3) of the unpermitted penetrations are located on the downstream face of the Marysville Blvd bridge at the upstream limits of the Arcade Creek South Levee, one SMUD conduit, one communication conduit, and one gas main assumed to be owned by PG&E. The other unpermitted penetration is a four (4) inch communication line through the Arcade Creek south levee immediately upstream of Rio Linda Blvd and is assumed to be owned by Century Lync.

Work plan: SAFCA (via Mead & Hunt) or ARFCD will perform initial outreach to CVFPB for a more in-depth review of files related to these penetrations. SAFCA (via Mead & Hunt) will notify utility owners of the need to provide appropriate documentation for utility land rights and permits.

If data documenting permits (or lack of permitting) are not provided within one (1) year of transmittal of the ULDC Engineer’s Report, the responsible land use agency will engage the CVFPB for enforcement. Owners will be required to obtain permits or relocate penetrations in order to comply with current CVFPB standards.

Completion of the required work plan, which may include collection of documents and reporting, shall be transmitted to the responsible land use agency (City of Sacramento/Sacramento County) Technical Memorandum

and appended to the ULDC Engineer’s Report. This supplemental information shall be retained and used for review by the land use agency during future ULDC evaluations.

2.1.6 Lack of Inspection Data
Exception background and assessment: Due to owner access issues (such as lack of access points, underwater access points, steepness of pipe limiting camera equipment mobility, small diameter pipes with no test stations, and other factors), there are numerous penetrations within the ANLS that have not met the internal inspection requirements under ULDC 7.13.6 for pipes and culverts. The ARFCD and SAFCA (via Mead & Hunt) have worked with the penetration owners to identify the inspection needs and notified them of their requirements. Most of these penetrations belong to the City, County, and other utilities (such as PG&E). The owners of these penetrations are working through their most recent cycle (every five years) of inspections/testing or are obtaining the resources to conduct the initial inspections within the following year. Due to land use and access issues, there is an anticipated delay for some of this work. Attachment No. 3 to this TM is a table summarizing penetrations requiring inspection documentation as of the date of this TM.

There are no historic issues at the locations of these penetrations and, with the exception of pipes flagged for additional scrutiny due to age in Section 2.1.4 above, the pipes are within their useful service life.

Work plan: Inspection data for ANLS penetrations that have not been received at the time of the transmittal of the Final ULDC Engineer’s Report shall be completed within the next three (3) years, or the land use agency will report this missing information to the CVFPB to request the missing information be required as part of an appropriate enforcement action.

Any penetrations inspected and found to be potentially high hazard will be prioritized by SAFCA (via Mead & Hunt) based on the level of risk and must be removed or modified. All mitigation efforts must be implemented within five (5) years of the finalization of the ULDC Engineer’s Report. The removal or modification/permitting efforts must be completed by the penetration owner or as part of a CVFPB Enforcement Action.

Completion of the required work plan, which may include collection of documents and reporting, shall be transmitted to the responsible land use agency (City of Sacramento/Sacramento County) and appended to the ULDC Engineer’s Report. This supplemental information shall be retained and used for review by the land use agency during future ULDC evaluations.

Mead & Hunt has concluded that the work plans described in Section 2.1 provide the necessary risk management of penetrations and have determined that the reliability of performance of the ANLS is unlikely to be affected for the full range of loading up to the HTOL. However, due to aging infrastructure and the period between each due diligence review, there are limitations to the conclusions included in this TM. All conclusions are 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 is completed as outlined herein and in the manner described in our Due Diligence Report. Particular attention should be paid to documenting the performance and condition of penetrations that are anticipated to be at the end of their useful life.

ARFCD Rodent Abatement Program
Revised October 2017. 1
Rodent Control &
Abatement Program
Burrowing animals can present a significant threat to levee integrity including increasing the potential for erosion and seepage. Animal control and damage repair must be routinely performed on levee systems to ensure functionality of the flood protection system. This document describes the rodent and animal control program administered by the American River Flood Control District (District). The program focus is in the control and removal of rodent populations from the District levee and drainage system, as well as the repair and mitigation of damage caused by rodent activity.

The District has a three pronged abatement program for the California Ground Squirrel. This program is timed throughout the year to make the most effective use of available methods for the best result and to provide the best levee integrity as the Sacramento area enters the flood season of November to April.

In the spring while the ground is moist, we begin by locating the burrows that are recently excavated by the squirrels as they awake from their winter hibernation. Pin flags mark the locations and we then begin using smoke bombs at each location to control the population. The holes are covered with a dirt filled sand bag that will be removed later in the year to insure that we grout all burrows. The locations are recorded with a handheld GPS to assist in the tracking of the problem areas and to facilitate reporting out usage to the Sacramento County Agriculture department.

Later in the summer when the soil is dry and smoke bombs lose their effectiveness, due to the porosity of the soil and also when the grass becomes dried out and a fire hazard, we switch to bait stations. The bait stations are specifically for the ground squirrel and are labeled with ARFCD contact information as well as all necessary information about the contents. The bait stations are secured to the ground with a steel strap and two 3 foot rebar stakes. Using the recorded data that indicates areas of concern, we position the bait stations and service them weekly until the squirrel problem is eliminated Additionally we use traps in some areas. Traps are generally set in the morning and removed late in the day. However in some areas they may be left overnight. They must be checked daily. A rolled oats horse feed called "Wet Cobb" is an effective non-poisonous bait. The trapped animals are euthanized in a CO2 containment device.

As we approach the rainy season we re-evaluate the burrows and pin flag the areas the need filling. Our District, using a specially designed Grout Trailer then fills each problem burrow with grout. When grouting, the District typically uses a grout mix made up of 9 parts cement, 1 part bentonite, and water added to achieve 8 to10 inches of slump. Grout is pumped at low pressures to avoid damaging the embankment, starting at the lowest rodent hole and proceeding up the levee slope. These locations are typically GPS tracked and approximate volume of grout is indicated with a color coded flagging system.

Photographs of the damage and repaired site are recorded as well. When larger damage to the levee occurs due to existing rodent holes and dens, the District will use District forces to excavate and compact Revised October 2017. 2
the damage, and rebuild the levee slope or crown. This requires additional levee fill and aggregate road base materials if the roadway is damaged.

The combination of these methods keeps the ground squirrel population reduced; however the proximity to the wide expanse of the American River Parkway, provides a constant supply of the squirrels looking for new places to live. They also benefit from the urban nature of our levee system and proliferate around areas of abundant food that is sometimes provided by the fruit and nut trees as well as gardens that are located near the levees. Even though the ARFCD program is extensive, due to the constant repopulation from adjacent areas, there will always be a need to stay vigilant to keep Sacramento Flood Safe.

Beavers also present a threat to levee integrity and their presence is found throughout the District’s levee systems. ARFCD monitors the levees for beavers. Dens in the banks or levee are repaired by the District.

ARFCD Security Plan
ARFCD Security Plan
March 2024 1

SECURITY PLAN

1.0 Introduction
This Security Plan was developed to meet the requirements of the California Department of Water Resources Urban Levee Design Criteria, Section 7.18, issued in May 2012. It is intended to assist the local maintaining agency (LMA) in protecting the levee system “from acts of terrorism and other malicious or negligent acts.” This plan identifies the Security Director, security measures the LMA will undertake, and key assets and vulnerabilities within the levee system. Because site conditions and adjacent land uses change over time, this plan is a living document.

1.1 Security Director
The Security Director is the American River Flood Control District (ARFCD) General Manager and is responsible for the implementation of this plan. The Security Director is also responsible for establishing a chain of command for emergency operations. However, the chain of command for emergency operations is established in cooperation with ARFCD, the City of Sacramento, and the County of Sacramento and is described in the emergency planning documents for those agencies.

1.2 Review and Update
As indicated above, this is a living document. The Security Director shall review this plan on an annual basis and update as appropriate.

2.0 Components of Security
This Security Plan focuses on networked detection, physical security, and intrusion interdiction, each discussed below.

2.1 Networked Detection
Per ULDC, “(n)etworked detection provides for monitoring and reporting of security information between the levee maintaining agencies and the Intelligence Community.” Networked detection also includes promoting and improving awareness and reporting of suspicious activity by the neighboring community.

ARFCD relies heavily on its own routine patrols, Sacramento County Regional Park Rangers along the American River and the City of Sacramento Police Department along NEMDC and Arcade Creek patrol to monitor and report unauthorized activities and/or suspicious behavior on the levees. Because the ARFCD levee systems are in an urban area, and residential development is adjacent to the levees for a large extent, residents living adjacent to the levees frequently call ARFCD Security Plan
March 2024 2
ARFCD to report observations. Currently, ARFCD does not collect, store, or share data regarding the types of activities observed or monitored.

While ARFCD does not participate in Neighborhood Watch programs or other social media forums, it does promote an atmosphere of “see something, say something” through its annual newsletter and a special section devoted to community feedback on its website.

2.2 Physical Security
Per ULDC, “(p)hysical security is divided between deterrence, access control, intrusion detection, and levee performance alerting mechanisms.” One goal of physical security is to force intruders who enter restricted areas to do so knowingly, thereby establishing intent on the part of the intruders. However, as is the case for most levees, pedestrian and bicycle access to the levee is generally permitted to the public and is oftentimes encouraged for outdoor recreation activities. No public access, in the form of vehicular traffic of any form, is currently authorized along the American River north levee, NEMDC east levee, or Arcade Creek south levee, and no public access is authorized within any of the pumping plant facilities.

Unauthorized motor vehicles are prohibited in all cases. In some cases, motor vehicle access is authorized if a transportation right-of-way is established on the levee crown.

Deterrence consists of visible security measures to create an atmosphere of vigilance and security. ARFCD patrols all its levees on a frequent basis. Sacramento County Regional Park Rangers along the American River and the City of Sacramento Police Department along NEMDC and Arcade Creek provide frequent patrolling along the levees in park areas, locations with high pedestrian traffic, and where unhoused populations are common. ARFCD also utilizes signage indicating that unauthorized vehicular use is prohibited by law.

Access control is intended to stop, inhibit, or delay access by unauthorized persons. As previously indicated, access to the levee is generally open to the public, and therefore access controls are primarily in place to limit vehicular access. Welded steel gates, bollards, and large boulders are all used by the ARFCD to restrict access. Welded steel gates are used primarily at access points adjacent to public roads. Other types of gates are common on private lands adjacent to the levee. Bollards are used along bike trails, and large boulders are used in conjunction with gates to deter motor vehicle access to the levee slope. Access to penetrations (e.g., gates, valves, vaults) are typically locked to protect the public from injury and prevent unauthorized access and operation.

Intrusion detection consists of measures that enhance the ability to detect unauthorized intrusion.

Unauthorized (i.e., vehicular) access is uncommon, although evidence of use by off-road vehicles such as dirt bikes and ATVs is sometimes found. ARFCD does not utilize cameras to monitor its levees and relies primarily on patrols and observant residents to detect intrusion.

2.3 Intrusion Interdiction
Per ULDC, “(t)he goal of intrusion interdiction is to facilitate awareness of and investment in swift response to reported intrusions during high water or increased threat periods.” In most cases, ARFCD personnel will interdict intrusions it detects. If a situation is or appears to be hostile, ARFCD will alert the City of ARFCD Security Plan
March 2024 3
Sacramento Police Department. The Police Department also interdicts most intrusions by the unhoused population.

2.4 Levee Performance
ULDC recommends that sensor systems be considered for detecting levee performance issues. Examples include pressure and motion sensors, gages, and piezometers. Piezometers measure pore pressure, or head, in levees and their foundations. These measurements can indicate how well a levee is performing related to under and through seepage. Table 1 provides a listing of levee performance devices. The location and monitoring of these devised is documented in the levee operation and maintenance (O&M) Manual.

3.0 Assets and Vulnerabilities
The flood control facilities under the purview of the ARFCD are not limited to levees. They comprise features that may or may not be owned and/or operated by ARFCD, such as closure structures, pumping stations, relief wells, flood walls, etc. Table 1 lists the assets and vulnerabilities present through the ARFCD levee systems.

4.0 Security Measures
ARFCD employs a variety of measures to protect the levee systems from acts of terrorism and other malicious or negligent acts. Table 2 describes these measures.

ARFCD Flood Safety Plan 1
January 2018
1 Plan Introduction
Purpose
This Flood Safety Plan (FSP) outlines the American River Flood Control District’s (ARFCD or District) planned response to flood emergencies in or affecting Sacramento County and meets the requirements of Section 9650 of the California Water Code.

The purpose of the FSP is to ensure the effective performance of the District responsibilities in a flood emergency in collaboration with other jurisdictions performing emergency functions within and around the District. This FSP provides information, policies, and procedures that will guide and assist the District in efficiently dealing with flood emergencies.

This FSP allows implementation of the California Standardized Emergency Management System (SEMS) and is intended to be used in conjunction with the California Emergency Plan, and other local emergency plans, to facilitate multi-agency and multi-jurisdictional coordination in flood emergency operations within ARFCD boundaries.

Although this is a public document, appendices to this FSP contain specific procedures to be followed in flood response. The appendices contain sensitive material, such as personal contact information. Therefore, they are not public documents in their complete form – they are subject to restricted-use handling procedures.

Scope
The ARFCD is an independent jurisdiction with responsibility for the operation and maintenance of the levee system within its jurisdictional boundaries and other levees for which the District may have maintenance responsibilities as determined by agreements with other entities. While the District will work with, and assist if possible, the local jurisdiction(s) responsible for other public safety functions within the District, this FSP only contains detailed procedures for ARFCD emergency responsibilities. This FSP will describe the interaction with other jurisdiction(s), but the operation plans of other jurisdictions with public safety responsibilities within the area protected by ARFCD levees are only referend in this document.

This FSP will cover the following:
• District flood preparedness procedures
• District levee patrol procedures
• District flood fight procedures
• District recovery and after-action procedures

ARFCD Flood Safety Plan 3
January 2018
2 Concept of Operations
Situation Overview
The ARFCD is in the Sacramento Valley. Areas adjacent to rivers, sloughs, creeks, and drainage canals and other low-lying areas are subject to flooding. State and local protective facilities, such as dams, bypasses, and levees, afford a level of flood protection; however, the flood events of 1986, 1995, 1997, and 1998 demonstrated that there is still a significant flood threat in the valley.

Sacramento County is vulnerable to many flooding sources caused by river floods, levee failures and/or overtopping, drainage pump failure, flood gate and/or closure structure failure, dam failure, flash and localized stormwater flooding. These may produce large losses to public infrastructure and private property. Deep flooding caused by levee failure or overtopping remains a significant threat to valley locations.

The local land use agencies and levee maintainers have the responsibility for operations and maintenance along with emergency preparedness during a flood event. For the Sacramento area, the Sacramento Area Flood Control Agency (SAFCA) works with State and Federal authorities for flood management. Within SAFCA’s area of operation, the City of Sacramento, the ARFCD, Reclamation District (RD) 1000, and the State Department of Water Resources Maintenance Area 9 are responsible for levee maintenance and operations of the major levees that protect the urban area of Sacramento within the Sacramento and Sutter Counties. In addition to these entities, the U.S. Army Corps of Engineers (USACE) has authority under their Sacramento Bank protection program to assist the State with addressing long term bank protection projects along the Sacramento River and its tributaries.

The ARFCD is an independent special district in the central portion of Sacramento. The boundaries of the District generally follow the floodplain of the American River as identified at the time of District formation in 1927. The flood plain area provided protection by the District, shown in Appendix D: Maps, encompasses approximately 40 miles of levees along the American River and portions of Steelhead, Arcade, Dry and Magpie Creeks. The jurisdiction covers areas of North Sacramento and Sacramento south to Sutterville Road and 14th Avenue and areas of the County of Sacramento south of American River to Folsom Boulevard and Mayhew Road. The territory within the District boundary is characterized by flat and gently rolling land in the central portion of the city of Sacramento. The District provides flood protection to a specific geographic area.

The ARFCD is responsible for the following levee segments, drainage facilities, and flood control structures.

Sacramento River east levee Sacramento River Station 1000+00 to 1020+85 General Approach to Seasonal Flood Operations
District personnel will carry out routine preparedness activities at the beginning of flood season as described in this section.

Flood response levels for the ARFCD will be based on river stage for both the American and Sacramento Rivers. On the American River, stages should be predictable for up to eight hours.

On the Sacramento River system, depending on which dams are releasing the flows, advance warning of river stages may be as much as 24 hours. This section defines the specific level of commitment by the ARFCD for specific triggers.

Not all flooding in the jurisdiction may be based on river stage, refer to the City of Sacramento Emergency Action Plan (EAP) related to floods.

Routine Preparedness and Infrastructure Maintenance
District personnel perform the following routine flood preparedness actions:
• All levees are inspected weekly to determine the needed maintenance as well as to deter any unauthorized encroachments.
• All levees mowed multiple times during growing season. Often, due to late rains, the growth is vigorous and thick needing more attention than "average" years. • Rodent control begins in spring with smoke bombing and progresses to baiting once the first mowing is complete and the wild food supply is reduced. Grouting is scheduled in early fall.
• Pre-emergent Herbicides are applied during the winter months to all roadways to ensure an all-weather road surface.
• Storm and weather related tree fall is removed.
• Minor erosion areas are identified and repaired as needed. • All gates are checked and repaired and painted as needed.

ARFCD Flood Safety Plan 2
January 2018
• Post emergent herbicide is applied as needed to keep roadways clear and on slopes as needed to deter noxious weed populations from establishing. • Roadways are resurfaced with fresh gravel prior to the start of flood season. • Tree and brush trimming is completed during the winter months. • Flood Emergency supplies and materials are checked and resupplied as needed. Supplies include, 9,000 empty sandbags, 2,000 filled sandbags, 4,500 feet of visquine, 7,000 tons of rip rap, as well as other material for flood patrol and fighting. • All equipment is serviced and prepared for flood season. • Annual flood fight training is conducted with the DWR and County of Sacramento CMID members.
• County CMID inspectors are on call to assist ARFCD in a flood emergency. • Communications, including radios, satellite phones and cell phones are checked for proper operation.
• Contact lists are checked and updated.
• General Service agreements for emergency levee repair are updated with Teichert, Granite, and Nordic Construction.

Monitoring and Analysis
The District will monitor and analyze throughout the flood season the water conditions, elevations, and forecasts of rivers and creeks affecting the District’s levees for promptly identifying heightened threats to the integrity of the levees and drainage systems. The objective ot this monitoring is to identify conditions that warrant additional actions beyond routine flood season preparedness activities. The District’s flood stage monitoring consists of observing the readings from specific real-time, telemetered stream gages that report the conditions on water courses that affect potential flooding in the jurisdiction. For each gage location on a stream or water course, stages or flows have been categorized into three levels: monitoring stage, danger stage, and flood stage.

The real-time gages can be accessed through the internet through the California Data Exchange Center (CDEC) within the California Department of Water Resources website (www.water.ca.gov). CDEC includes links to the National Weather Service and links to satellite photos. CDEC provides information on all of California’s rivers and reservoirs. This allows direct monitoring of outflows at key dams affecting the District.

The Sacramento County also uses the Automated Local Evaluation in Real Time (ALERT) system for local creeks. ALERT was created by the National Weather Service to signal the City of Sacramento about possible flooding. ALERT provides continuous and automatic reports from river levels and rainfall gauges to help detect impending high water levels. The ALERT system website is maintained by Sacramento County and is located https://www.sacflood.org.

Flood Season Monitoring (Normal Conditions)
During flood season and under normal conditions, the District conducts the following monitoring:
• Monitor reservoir levels weekly or more frequently as necessary • Contact the FOC and the USACE to report encroachments • Monitor weather reports on a daily basis
• Monitor river levels on a regular basis (or two or three times per week) Flood Season Monitoring (Adverse Weather Conditions)
During flood season and under adverse weather conditions, the District conducts the following monitoring:

ARFCD Flood Safety Plan 5
January 2018
• Monitor weather reports/radar several times per day
• Monitor river/stream levels as necessary to initiate levee patrols at predesignated stages • Monitor reservoir levels on daily basis (or more often if significantly encroached)
• Monitor reservoir release schedule on daily basis once levee patrols are initiated (and more often during significant flood events)
• Participate in daily conference calls with County Office of Emergency Services Flood response levels and monitoring patrol frequency for the District are based on river stage.

Levee patrol frequency by river stage is described in Section 2.2.2.

Levee Monitoring
During flood season and under adverse weather conditions, the District takes the following levee monitoring actions:
• Notify staff when levee patrol operations requiring 24-hour monitoring are anticipated and adjust work schedules to accommodate
• Initiate levee patrols at pre-designated river, stream, or reservoir level • Follow the ARFCD Levee Patrol Plan (Appendix B: Levee Patrol Plan) • Notify outside levee patrol staff 72 hours in advance of need for assistance, if possible
• Determine the need for additional levee patrol assistance and potential sources of support
Alerting, Activation and Initial Response
The following actions will be taken when the trigger condition is identified by District staff.

These actions may also be taken by District staff at any time it is felt that conditions affecting the levees warrant such action.

After compiling monitoring and surveillance information, the ARFCD decides if it is necessary to begin flood operations or direct flood fight resources to specific areas where flooding is occurring or may occur soon. District staff also monitor the flood stage information or monitoring system and are in constant communication with flood control staff throughout the storm episode.

The following actions are taken depending on the severity of flood conditions. District staff may take these actions at any time it is felt that conditions affecting the levees and drainage system warrant such action.

ARFCD Flood Safety Plan 6
January 2018
• Alert the Board of Trustees and District staff
• Appoint an Incident Commander for the District
• Activate staff, notify contractors, and initiate levee-monitoring protocols as defined in Levee Patrol Plan. (Appendix B: Levee Patrol Plan) • Make notifications to the City and County
• Contact DWR Flood Operations Center (FOC)
The District does not use “phases”, where objective conditions trigger a group of actions. Each action indicated will be taken when District staff feels it is warranted, based on river stages and levee integrity. The District Superintendent and District General Manager are responsible for monitoring objective conditions affecting the District.

District staff will take all of the above actions on identification—or verified report—of any outof-the-ordinary condition on a District levee that presents a potential risk of failure.

If conditions exceed their capabilities on any of the levee systems, the District will call the Sacramento County or DWR for technical assistance. If conditions continue to worsen, the District may contact Sacramento County for mutual aid resources. The DWR FOC may request support from the USACE under PL 84-99.

As coordinated operations continue, local jurisdictions will brief their administrators. These positions often serve as the Directors for Emergency Operations at the Emergency Operations Center (EOC). Depending on the flooding situation, the EOC will be activated and staff will respond to the EOC to coordinate OA response to the disaster with other agencies.

The DWR FOC may also be made operational. County EOCs remain operational until the threat from flooding is contained and controlled.

Public Alert and Warning
The jurisdictions identified below have the responsibility for providing emergency response to the general public within the ARFCD boundaries. The District will promptly notify these jurisdictions of identified concerns with their levees in accordance with the Sacramento County OA protocols and will provide detailed information on the characteristics of the threat. • Sacramento County Office of Emergency Services
• Sacramento County Sheriff’s Department
The ARFCD will coordinate operations with these jurisdictions/agencies through the Sacramento OA. District staff will assist, to the extent possible, with public safety actions if requested.

Response producers for the above public safety agencies will be found in agency emergency plans.

ARFCD Flood Safety Plan 7
January 2018
Emergency Response Actions
The District emergency organization is mobilized to cope with specific situations. Each unit, when mobilized, operates according to the provisions of this FSP. Priority is given to operations such as the following:
• Survey and evaluate the emergency situation and advise the Sacramento OA EOC and the FOC
• Mobilize, allocate, and position District personnel and materials for levee monitoring and flood fighting
• Notify flood emergency contractors
• Establish staging areas for personnel, supplies, and equipment • Produce and disseminate emergency information
• Protect, control, and allocate vital resources
• Submit requests for resources and assistance
• Restore or activate essential facilities and systems
The preceding actions are based on extensive local coordination of plans and response. Also, there are daily briefings facilitated by DWR from the FOC involving all impacted agencies.

When local resources are committed to the maximum and additional materials or personnel are required to control or alleviate the emergency, requests for resources are initiated through the Sacramento OA EOC.

Flood Fight Operations
Flood fight operations, including levee patrol and repair, are conducted in accordance with the procedures in this FSP. Operations and response procedures are modified as needed by the District Incident Commander to meet the demands of actual emergency conditions. Both the City and the County have Emergency Evacuation Plans and are responsible for warning and evacuation within the District. An inventory of flood fight supplies may be found in Appendix C: Flood Fight Resource Inventory. Flood fight operations, including levee patrol, will be conducted in accordance with the procedures in Appendixes B and C.

Evacuation
Certain flood threats to the District, as they grow in severity, may require evacuation of populations of residents and/or visitors. The evacuation planners need to determine the lead-time needed to get the necessary resources deployed to the field and the estimated time to conduct a floodplain evacuation. Determination of the proper lead time is made as part of the initiation coordination calls with the Sacramento OA and DWR. Examples of these flood threats may include:

ARFCD Flood Safety Plan 8
January 2018
• Weather reports that include flood watches or warnings and/or storms that may bring large amounts of rain
• Reservoir release forecasts that equal or exceed downstream safe levee capacity • Active river bank erosion that is threatening levee stability • Dam failure advisories for dams anywhere along the Sacramento River, American River, or Cosumnes River watersheds
• Levee breach advisories for levees protecting District populations When these conditions threaten the District, the District notifies threatened jurisdictions (i.e., the City and the County). After the decision to evacuate is reached, the City and the County coordinate with the District to manage the evacuation process so as not to affect emergency response activities. Coordination of evacuation efforts in the County is managed from the Sacramento OA EOC, and the coordination of evacuation efforts in the City is managed from the City of Sacramento Emergency Operations Center (City EOC). Additional information about evacuation is provided in the Sacramento County Evacuation Plan and the City of Sacramento Evacuation Plan.

Recovery
An effective recovery requires coordinating with several government agencies over an extended period. Recovery activities may include:
• Organizing files from emergency operations
• Gathering pictures, memos, notes, and other written information from those involved in the emergency response
• Creating a list of outside contacts made during response, including resource and regulatory agency contacts
• Organizing the contracts executed, invoices from contractors/material suppliers, and documented labor costs from the emergency response
• Initiating claim procedures with FEMA and the California Governor’s Office of Emergency Services (Cal OES)
• Conducting a post-flood survey of the District’s flood control system to determine areas needing immediate emergency repairs
• Determining if the District has the financial resources to undertake repairs; if not, seeking assistance from State and USACE (under Public Law 84-99 or other appropriate State or Federal program) to implement immediate repairs • Conducting a post-flood-season survey to determine which sites were not addressed by the post-flood survey but need to be repaired before the next flood season ARFCD Flood Safety Plan 9
January 2018
Other recovery activities may include:
• Rebuilding levees
• Dewatering protected areas - reference City of Sacramento Emergency Action Plan • Clearing debris
• Demolishing unsafe structures
• Re-entering of District residents
• Performing research to uncover residual hazards, to advance knowledge of disaster phenomena, and to provide information to improve future flood Federal and State Emergency and Disaster Assistance
The ARFCD may maintain mitigation and emergency plans and procedures, as well as, the physical condition of its levees, at the level required to be eligible for disaster assistance under the Federal Stafford Act program as well as the California Disaster Assistance Act (CDAA).

Emergency operations will be conducted and documented in compliance with conditions of these programs for reimbursement of disaster expense.

State and federal support during the Emergency Phase:

To ensure that the district takes steps to quickly access the recovery process, these actions should be considered if an incident is imminent or occurring:
• The ARFCD in coordination with SAFCA and Sacramento County staff will request the County to proclaim the existing of a local emergency and notify ARFCD staff when the proclamation is established.
• The ARFCD in coordination with Sacramento County may consider requesting Cal EMA and DWR support during the Emergency Phase. California Mutual Aid and USACE assistance are available when resources beyond local capability are needed for flood fight operations.

Emergency Phase support following flooding:
• If the County declares a disaster, the Governor may support it by proclaiming a State of Emergency and then requesting the President make a National Disaster declaration for the affected area.
• If the President declares the area a national disaster, assistance from the Federal Emergency Management Agency (FEMA) will be requested.
• If residential flooding occurs, regardless of the declaration, USACE can provide federal funds for recovery operations for up to 30 days following the incident.

ARFCD Flood Safety Plan 10
January 2018
• USACE assistance can also be requested to repair eroded and damaged levees following high flows. Request for this authority must be made in a timely manner (30 days).

3 Organization and Assignment of Responsibilities
Levee Flood Control Operations
The District will use its paid and contract staff to perform its responsibilities in a flood emergency. The District can request mutual aid and coordinates with the Sacramento County OA during flooding episodes.

Key Designated Roles
The ARFCD Board of Trustees (Board) has made the following assignments of authority and responsibility to ensure that needed emergency actions can be taken promptly and efficiently.

Annually, the Board designates responsibility to the General Manager for Emergency Operations.

Legal and Financial Authority
Once the Board has concurred that a local emergency is occurring, any one trustee and the District General Manager are authorized to (1) make a legal or financial commitment on behalf ARFCD Flood Safety Plan 12
January 2018
of the District during emergency operations and (2) purchase additional flood fight supplies or materials. Even without prior Board concurrence that a local emergency is occurring, the General Manager can take these actions on recognition of a threat to levee integrity, but in this case the Board must be notified of the action within 24-hours.

The District General Manager is authorized to sign written contracts with private vendors or other public agencies stemming from emergency actions, as described above.

Multi-Agency Coordination Group Representation
The District Superintendent is authorized and responsible for representing the District in the unified field-level incident command that may be established by the Sacramento OA. The District Superintendent is also responsible for representing the District at the Sacramento OA management group. The District Superintendent may speak for the District in matters of the condition of District levees, input to protective action decisions being made by public safety agencies, and any requests to modify or conform the District’s response that come out of the multi-agency coordination process.

Public Information and Risk Communications
If required, the District General Manager is authorized to speak to the media on behalf of the District as part of the Sacramento OA Joint Information Center (JIC). The District also updates its website with information related to District activities.

Although the District does not have a dedicated Public Information Officer (PIO), the General Manager will coordinate with the City of Sacramento (City) and the County to get critical information to the public. The City and the County have PIOs that will manage the dissemination of information to the public, either through press releases, press briefings, or social media.

Evacuation
The City is responsible for coordinating the evacuation of residents and visitors in the District.

The City Manager has the authority to issue evacuation recommendations and the City Police Department manages the evacuation. The City of Sacramento Evacuation Plan describes the Concept of Operations for evacuation in the City limits. The City is responsible for the following regarding evacuation:
• Recommending evacuations for all or part of the population from a threatened or impacted area if considered necessary for preservation of life, property, or the environment
• Prescribing routes, modes of transportation, and destinations in connection with evacuation
• Controlling ingress and egress from a disaster area, the movement of persons, and the occupancy of premises in the area
ARFCD Flood Safety Plan 13
January 2018
Maintaining Emergency Equipment, Supplies, and Resources The District Superintendent is authorized to maintain District equipment, supplies, and resources for emergency response and is responsible for doing so. The Superintendent ensures that supplies are maintained at inventory levels set by the Board or at any minimum levels that may be set by DWR guidance or statutes.

Monitoring Levees, Water Conditions, Elevations, and Flood Forecasts The District Superintendent is responsible for monitoring levees, water conditions, elevations, and forecasts for identifying conditions warranting additional action beyond routine flood preparedness as outlined in this plan.

Emergency Staff Activation
The District General Manager and District Superintendent are authorized to activate—and are responsible for doing so—District staff and/or flood response contractors and resources; to request Mutual Aid assistance from (or provide it to) public agencies; and to supervise District staff, contractors, and/or Mutual Aid resources assigned to the District for (1) levee patrol, (2) flood fight operations, and (3) District de-watering operations (if applicable).

Documentation
The District Office Manager is authorized to maintain necessary documentation of emergency expenditures, damage to District infrastructure, and use of supply inventories in accordance with the requirements of Federal and State disaster assistance programs and is responsible for doing so.

The District Office Manager, under the authority of the District General Manager, is also authorized to prepare and submit disaster assistance claims during the recovery period through all Federal and State disaster assistance programs that may be applicable and relevant to District costs and is responsible for doing so.

Responsibilities of Supporting Agencies
During a levee breach and/or flood fight operation, the District may request support from other agencies. These agencies and their responsibilities are identified below.

California Department of Water Resources
The mission of DWR’s Division of Flood Management is to prevent loss of life, reduce property damage caused by floods, and to assist in recovery efforts following any natural disaster. The State-Federal FOC, which is in Sacramento, is a component of Division of Flood Management’s Flood Operations Branch. Year-round, the FOC is the focal point for the gathering, analyzing, and disseminating of flood- and water-related information to stakeholders. During emergency situations, the FOC provides a facility from which DWR can centrally coordinate State-wide emergency response.

ARFCD Flood Safety Plan 14
January 2018
When streams and rivers are forecast to rise above certain pre-determined stages (water surface elevations) or flow rates, FOC personnel make high-water notification calls to appropriate flood system LMAs and emergency response agencies.

DWR also provides staff to the California State Reclamation Board; assists local flood control districts, particularly during flood events; monitors river and reservoir levels; and operates the FOC as described above. In addition, DWR is responsible for operation and maintenance of a number of levees in the Central Valley through State Maintenance Areas and a number of dams and reservoirs. DWR also has a significant role in water supply.

U.S. Army Corps of Engineers
When a disaster exceeds the capabilities of State and local interests, the USACE may provide assistance under Public Law 84-99 to save human life, prevent immediate human suffering, or mitigate residential and commercial property damage. USACE assistance may include acquisition of flood fight materials, geotechnical evaluation of levees and other flood operations structures, contracts for emergency flood fight and temporary repairs, clearance of drainage channels or blocked structures, technical assistance for development of plans, and, on request, inspection of non-Federal dams and flood control projects. USACE also has jurisdiction over storage capacity seasonally reserved for flood control on most major reservoirs throughout California.

California Data Exchange Center
The California Data Exchange Center (CDEC) provides a centralized database to store, process, and exchange real-time hydrologic information gathered by various cooperators throughout the State. CDEC disseminates this information to the cooperators, governmental and private agencies, news media, and the general public. The data collected by CDEC enables forecasters to prepare flood forecasts and water supply forecasts, reservoir and hydroelectric operators to schedule reservoir releases, water suppliers to anticipate water availability, and flood emergency personnel to prepare and disseminate flood hydrology data and reports.

CDEC formats and manages data for public use via the Internet. Its extensive website is accessible to flood emergency personnel, private and public agencies, news media, and the general public. Valuable information is created from the data and presented in a variety of formats, including maps, plots, charts, and publications. The website is a useful and effective tool for monitoring current flood conditions and provides real-time information, including river stages, precipitation, snow water content, temperature, water quality, and full weather data.

State of California Central Valley Flood Protection Board The State of California Central Valley Flood Protection Board oversees flood control activities in the Central Valley. It serves as the local sponsor to the USACE on Federal flood control projects, cost-shares in the projects, holds title or easements to the lands underlying the projects, and inspects the operation and maintenance of the facilities by the local flood control and reclamation districts. The board is the regulatory authority about any proposed activity that could affect the flood control system.

ARFCD Flood Safety Plan 15
January 2018
City of Sacramento Department of Utilities
The City of Sacramento Department of Utilities (DOU) primarily operates and maintains water and wastewater systems, including local drainage systems, which consist of storm drains, culverts, pumping stations, and channels with levees. These drainage systems pump water into the levee systems. Also, DOU operates and maintains local levees and the portions of the Sacramento and American River levee systems that are outside the boundaries of the ARFCD.

County of Sacramento Department of Water Resources
The County of Sacramento Department of Water Resources (County DWR) provides drainage, water supply, and flood control services to areas within their jurisdiction. County DWR consists of a Drainage Division and a Water Supply Division, with the Drainage Division Maintenance Engineering Section having primary responsibilities in flood operations. During storm events, County DWR activates a Department Operations Center (DOC) and a Field Support Operations Center (FSOC) and provides staff to the County of Sacramento Emergency Operations Center (County EOC) to coordinate activities and share information. County DWR staff actively monitor rainfall and stream flow conditions through the County Automated Local Evaluation in Real Time (ALERT) gage system, provide field crews for emergency maintenance and levee patrols of several small County-maintained levees, and assist emergency personnel in floodrelated activities. County DWR field crews respond to service calls made to the 875-RAIN dispatch center related to localized flooding throughout the County and have primary responsibility for carrying out the operation and maintenance of pipe, pump, and channel drainage systems.

County DWR serves as the floodplain management agency for the County. As such, the agency is instrumental in preparing a County-wide perspective on flood preparedness and flood fight efforts in the area. County DWR plays a key role in gathering, analyzing, vetting, and disseminating weather forecast and water level information County-wide and communicates this information directly to potentially impacted parties, such as Reclamation Districts (RDs), incorporated cities, and local communities. County DWR also provides assistance to RDs in the form of levee patrol support crews and water removal through pump stations.

County DWR also maintains the County’s Storm Ready Program, which informs the public about flood safety and actions that should be taken during a flood threat.

County of Sacramento Office of Emergency Services
The County of Sacramento Office of Emergency Services (County OES) has responsibility for administering the emergency management program for the County. As part of this responsibility, County OES supports the operation of the Sacramento OA Emergency Operations Center (OA EOC), issues warnings and notifications, provides subject matter expertise on and maintenance of emergency response plans, and coordinates requests for resources and assistance when the OA EOC is not activated.

ARFCD Flood Safety Plan 16
January 2018
4 Direction, Control, and Coordination
Management and Control of District Operations and Coordination within the District
District staff authorized and responsible for carrying out the actions use the direction, control, and coordination processes described in this chapter.

District staff apply the Incident Command System (ICS) and SEMS to organize District response activities, manage field-level response activities, and coordinate with supporting agencies.

The General Manager serves as the Emergency Manager for the District during emergency operations. The General Manager supports the Incident Commander and coordinates with the City when additional assistance is needed and to share critical information.

Management and Policy
The District maintains direction and control of District operations during emergency periods.

The District Board of Trustees meet and confer as deemed necessary by the President during emergency operations to perform its policymaking and financial responsibilities during emergency response operations. Board meetings occur in the field or, if needed, at the office of the District.

The Board President issues Delegation of Authority letters as required.

Incident Commander
The Incident Commander at the flood fight scene is in charge of all resources responding to that emergency site. The Incident Commander may assign missions to flood fight crews acquired under Mutual Aid from other governmental agencies, tasking them to perform specific actions to facilitate the response.

The District Superintendent serves as Incident Commander to manage all incidents occurring on the District levee system during any single disaster event as allowed in the NIMS protocols. The District operates on a 24-hour operational period. If necessary, the Incident Commander requests assistance from the District General Manager.

Management and Coordination with Other Jurisdictions
During a flood threat incident, the District maintains regular communication with the FOC, the City EOC, and the County OA EOC. Through the FOC (and information on the DWR website), the District provides updates on the conditions of the levees and receives information about the reservoir levels and anticipated releases. The District may also seek technical assistance on handling levee problems. The FOC has representatives from the National Weather Service, U.S.

Bureau of Reclamation, and USACE available to provide information and assistance. The City ARFCD Flood Safety Plan 17
January 2018
EOC coordinates the local emergency response. The District provides regular updates on the conditions of the levees and observed river levels. The District may also ask for assistance (e.g., traffic or crowd control or other emergency response) from law enforcement and/or fire departments through the OA.

For flood threats, a multiagency coordination (MAC) group may be established to share information and facilitate the coordination of resource requests. The City, County or State depending on how widespread the flood threat is can facilitate the MAC Group. The MAC Group includes the participation of representatives from all agencies that have an active role in the coordinated flood response. The MAC Group can meet in person, but is commonly convened as a conference call on a pre-set schedule.

Either as part of MAC Group participation or through direct communication with the City and/or County, the District will provide updates on the conditions of the levees and observed river levels. The District may also request assistance (e.g., traffic or crowd control or other emergency response) from law enforcement and/or fire departments through the Sacramento County OA.

Sacramento Operational Area Emergency Operations Center The County maintains and hosts the Sacramento OA EOC at 3720 Dudley Boulevard, McClellan, CA. The Sacramento OA EOC prioritizes the allocation of resources, including Mutual Aid; performs information sharing; and conducts coordination processes in accordance with the MAC system procedures maintained by the County OES.

The Sacramento OA Planning Section provides disaster intelligence and situational status to participating jurisdictions on activation in an emergency. The District participates as needed in this disaster intelligence and information-sharing process.

The District General Manager participates in the Sacramento OA MAC system processes and procedures on behalf of the District.

State-Federal Flood Operations Center
DWR has special authority under California Water Code Section 128 to assist RDs with flood fight operations. DWR maintains the FOC to coordinate the performance of these functions and support the operations of other State and Federal agencies.

The District coordinates with the FOC to share information and to notify DWR of requests submitted to the Sacramento OA for resources and technical assistance. The District communicates with the FOC through telephone systems or at MAC activities where FOC representatives are present.

Sacramento Operational Area Joint Information Center
When necessary, a JIC is established to coordinate the handling of Emergency Public Information operations for the County and the OA. A JIC is established at a suitable location (removed from the EOC, but in close proximity to it) to provide for effective management of Emergency Public Information functions. When activated, the JIC is staffed by personnel trained ARFCD Flood Safety Plan 18
January 2018
to conduct Emergency Public Information activities, including coordinating inter-jurisdictional media releases and the management of rumor control functions. When necessary, the District General Manager coordinates with the JIC to share information with the public.

Plan Activation Authority
The District Board of Trustees and the District General Manager have the authority to activate this FSP based on the emergency situation.

Disaster Intelligence
During river and levee monitoring and flood fight operations, the District collects disaster intelligence to evaluate the situation and provides updates to supporting agencies. Disaster intelligence is the means, the tools, and techniques the District uses to identify, collect, analyze, and disseminate information on the current and future extent and consequences of a flood.

Intelligence is shared primarily with the City EOC, the Sacramento OA EOC, and the FOC.

Weather Forecast
The advent of satellite imagery and sophisticated computer models has significantly improved the ability to forecast the times and intensities of rainfall. Managing flood response requires knowledge and understanding of the implications of weather predictions for other parts of the watershed and the local area. The National Weather Service provides daily briefings on upcoming weather as part of its role in the FOC. The District participates in these briefings starting at the River Advisory Stage.

River Forecast
In addition to precipitation forecasts, the District General Manager must also know how the resulting runoff affects reservoir storage, releases from dams, and ultimately the amount of water flowing in the river. Hydrologists for DWR work with the National Weather Service in the California-Nevada River Forecast Center (CNRFC) to provide twice-daily forecasts of river height at various points. These forecasts are issued as “River Bulletins,” and the District subscribes to DWR’s email distribution system. Also, the District regularly reviews the website of the CDEC, which provides data on reservoirs, rivers, and rainfall (http://cdec.water.ca.gov/).

Levee Patrols
As important as it is to anticipate the potential situation, it is equally as vital to be aware of current conditions and sudden shifts in those conditions. The District Superintendent maintains regular contact with levee patrols. This contact ensures that the District quickly learns of any changes in the situation, facilitating prompt response. Levee patrols are defined in Levee Patrol Plan, in Appendix B.

ARFCD Flood Safety Plan 19
January 2018
5 Communications
Communications Organization
During day-to-day operations and flood response operations, District staff, contractors, and other staff working under District supervision must be able to communicate and share information. At a minimum, the District must be able to communicate internally with other public agencies operating within the District, neighboring RDs, the Sacramento OA EOC, and the FOC.

District Communications
The District operates communications equipment on a limited basis, including the use of Satellite phones; landlines – both digital and analog; fiber optic cables, and emergency radios. The District relies on the personal cell phones of its staff and trustees to maintain communications between the District Board of Trustees, the District General Manager, the District Superintendent, and other response staff that may be hired during the emergency period. In the event of a failure of cellular telephone systems, the District will use messengers to transmit information between its staff and other jurisdictions and regularly scheduled coordination meetings of the field unified commands and the Sacramento OA organization.

Communicating with Other Jurisdictions
The District maintains communications with other jurisdictions by cellular telephone and by participation in meetings of the Flood Fight Incident Command and MAC groups.

Sacramento Operational Area Emergency Operations Center The District maintains communications with the Sacramento OA EOC by cellular telephone and participates in scheduled meetings of the MAC groups. The District maintains telephone numbers assigned by the OA for use by RDs (see Appendix A: Emergency Contact List).

State-Federal Flood Operations Center
The District communicates with the FOC by cellular telephone.

Public Alerting Systems
Public alert and warning is necessary to increase public awareness of an impending threat and to provide clear instructions should an emergency situation require the need for evacuation. In fact, the vital first step of a successful evacuation from the District would be timely public alerting that allows the public the opportunity to safely move to non-impacted areas.

During public alert and warning, the District promptly notifies the City of Sacramento Office of Emergency Services (City OES) or County OES, depending on the jurisdiction impacted. Both the City and the County are responsible for alerting and warning the public on identification of a ARFCD Flood Safety Plan 20
January 2018
threat to District levees. The District provides detailed information about the characteristics of the threat and assists, to the extent possible, with notification of the public if requested. All alerting and warning of the public are carried out in accordance with the plans of protected jurisdictions.

When multiple jurisdictions are impacted, alerting and warning are conducted jointly by these jurisdictions through the Sacramento OA using the procedures contained in the Sacramento OA EOP. The District provides support to the OA and JIC to assist with alert and warning messages if requested.

The City and County use several methods to notify the public of an evacuation request. These methods include:
• Emergency siren system
• Emergency alert system (EAS)
• Media hotline and media release
• Reverse 9-1-1 system
• 2-1-1 Sacramento
• Fire and police vehicle loudspeakers
• County Information Services: Sacramento County Information Center and County Operator
• Vulnerable population databases, neighborhood watch programs, and other community support programs
• Neighbors alerting neighbors
People with disabilities and access and functional needs are be notified by support service agencies. Also, the City Operator and the 3-1-1 system are available for the notified public to call for more information.

Those who are evacuating throughout the County or out of the County continue to receive information as to road conditions through the California Department of Transportation (Caltrans) 5-1-1 system for highway conditions, Caltrans changeable message signs, and via EAS on local radio.

Emergency Alert System (EAS)
The EAS is a network of public and private broadcast stations and interconnecting facilities. The system is authorized by the Federal Communications Commission (FCC) to operate in a controlled manner during a war, state of public peril or disaster, or other national emergency.

The system is used within Sacramento County on a voluntary basis during day-to-day situations that pose a threat to the safety of life and property. Sacramento County uses a commercial ARFCD Flood Safety Plan 21
January 2018
broadcast facility – (radio KFBK or television KCRA) – as the central point of information dissemination under the EAS format. Access to EAS is coordinated through the Sacramento County Office of Emergency Services. (Please refer to Appendix D Evacuation).

The City of Sacramento manages the Emergency Alert System and is described in their City of Sacramento Evacuation Plan
Protocols for Contacting Levee Patrols
Initial contact with the Levee Patrol Team(s) shall be in accordance with the Emergency Contact List (Appendix A). Generally, communications with Levee Patrol Teams will be through the General Manager.

Other Communications Protocols
All other communications shall be in accordance with the Incident Communications Plan, as documented on Incident Command System (ICS) forms ICS 204 and ICS 205.

ARFCD Flood Safety Plan 22
January 2018
6 Administration, Finance, and Logistics
Mutual Aid
The ARFCD has mutual aid agreements with the City and the County to provide supplemental staff during floods for round-the-clock levee patrols. The District has also signed agreements with local contractors, who are ready to respond 24 hours per day, 7 days per week, with trained personnel, equipment, and material (such as rock, aggregate base, sand, and fill dirt) if a levee is threatened. Relying on these agreements with the City, the County, and local contractors allows the District to provide services efficiently with a high level of reliability.

Record Keeping
The District General Manager tracks, records, and reports on the work time of all District flood response personnel, including that of flood emergency contractors. The District General Manager collects and maintains documentation on all emergency information needed for reimbursement by Cal OES or FEMA. The ARFCD retains these records for audit purposes for 3 years after receiving a final Cal OES or FEMA close-out letter. Examples of documentation that should be retained include:
• Timesheets and payroll records
• Equipment ownership and usage
• Equipment rental agreements and invoices
• Invoices/receipts for materials and supplies
• Contract documentation such as procurement information, executed contracts, amendments and change orders, and payment records
Resource Tracking
Comprehensive resource management is a key management principle. It implies that all assets and personnel during an event need to be tracked and accounted for. Resource tracking ensures maintenance of accountability over all resources. Thus, resources can be moved quickly to support preparation and response to an incident and ensure a fluid demobilization.

Resource management involves coordinating and overseeing the acquisition and deployment of tools, supplies, equipment, and people during a flood. The objectives of resource management are to (1) maximize efficient resource use while maintaining cost-effectiveness and resource safety; (2) consolidate control of single resources to reduce communications activity; and (3) instill resource accountability. Resource management enhances the benefit of Mutual Aid agreements and improves interoperability.

ARFCD Flood Safety Plan 23
January 2018
Flood response resources include (1) personnel or equipment to perform a specific operation; and (2) supplies and facilities to support on-scene incident operations. The District Office Manager tracks the use of and maintains records on the resources applied to flood response.

Resources
The District maintains an inventory of flood fight supplies. The inventory is found in Appendix D: Flood Fight Resource Inventory.

Flood Response Contractors
Should a problem be identified on the levees, the District uses resources from the City or County to monitor specific locations as necessary. If the problem requires action such as reinforcing the levee by placing dirt, sandbagging a boil, or armoring a levee slope with rock and visquine, the District has flood emergency response agreements executed with several local contractors. These agreements provide for an immediate response 24 hours per day, 7 days per week. The companies currently under contract have extensive experience in providing similar emergency flood services. Determinations of the appropriate action are made by the District General Manager with input from local levee experts, the State Flood Fight Specialist, and engineers from USACE. Full-time monitoring and record keeping are performed by County construction inspectors.

The District maintains standard forms and processes for initiating and executing contracts with private vendors. The District maintains a standard contract form for contracts under $25,000 in a no-bid environment. The District maintains a separate contract form for contracts over $25,000, adding a bonding requirement. Contracts over $25,000 are awarded through an informal bid process.

Logistics Facilities
See Appendix C for the locations of pre-planned delivery points, the locations of District supplies, and District supply staging areas and points.

Finance and Administration
The District maintains financial and administrative records associated with emergency response in accordance with Title 44 Code of Federal Regulations Part 13, Uniform Administrative Requirements for Grants and Cooperative Agreements to State and Local Governments.

Emergency response and construction records, including field reports and procurement and construction management files are maintained by both the District and the District Superintendent and are retained as prescribed by the grant authority.

Also, in anticipation of a flood emergency, the District has established a Flood Fight Reserve Fund. Currently, the fund has approximately $1 million, which is estimated to be sufficient for a 2- to 3-day flood fight.

ARFCD Flood Safety Plan 24

7 Plan Development and Maintenance
Plan Development, Review and Maintenance
The General Manager has primary responsibility for developing, reviewing, and updating this FSP on a regular basis. The General Manager will request input from individuals, jurisdictions, and agencies having responsibilities under this plan.

Every four years this plan will be reviewed in its entirety, updated, republished, and redistributed. This plan also may be modified whenever responsibilities, procedures, laws, rules, or regulations pertaining to emergency management and operations change. • Jurisdictions and agencies having assigned responsibilities under this plan are obligated to inform the General Manager when changes occur or are imminent. • These changes will be incorporated into this plan, published, and distributed to jurisdictions and agencies holding this plan (see Distribution List).

Training and Exercises
All emergency responders from ARFCD are strongly encouraged to take advantage of FEMA’s on-line training. In addition, the General Manager of ARFCD will notify holders of this plan of training opportunities or scheduled exercises associated with flood emergency management and operations, such as DWR’s annual Flood Fight sessions. Individual jurisdictions and agencies are responsible for maintaining training records. This plan will be exercised regularly. The General Manager will conduct emergency preparedness exercises in accordance with an annual exercise schedule. Jurisdictions and agencies having assigned responsibilities under this plan must ensure assigned personnel are properly trained to carry out these responsibilities.

Evaluation
The General Manager will coordinate and facilitate post-incident analyses following emergencies and exercises. An After-Action Report (AAR) and Implementation Plan will be prepared by General Manager and distributed to those jurisdictions and agencies involved in the emergency or exercise. The Board of Trustees will review and approve the AAR which will briefly describe District operations, any response problems that arose, and damage sustained by the District levees and infrastructure. The AAR will also contain recommendations for improving flood emergency operations in the future. The Board provides direction to staff on the preparation of changes, additions, or revisions to the District FSP.

Appendix B Levee Patrol
B.1 Purpose
The purpose of levee patrols is to have qualified personnel visually evaluate the performance of the District levee system. Their intent is to determine the condition of the levee and to identify potential and existing problems:
• Threats
• Instabilities
• Seepage conditions
• Erosion points
• Freeboard
Implementation of this procedure will ensure each member of the Levee Patrol Team is capable of participating in precautionary actions and emergency response that may occur with the District’s levee system.

This program will predominantly be undertaken by the District, with operational support from the Sacramento County. The major objectives of this procedure are to:
• Develop a training program to ensure qualified personnel are available for use • Ensure materials, equipment and supplies are available to implement this procedure and are maintained in a serviceable condition to meet the needs of the ARFCD • Ensure action levels are established and in place to manage potential challenges • Prepare members to recognize the interface between allied agencies should escalating events require large-scale operations
• Prepare members to patrol levees to locate potential problems (including vandalism or terrorism), to alert the EOC, and to actively coordinate work, using flood fight and other methods, to resolve problems and minimize adverse consequences B.2 Program Elements
The levee patrol program has three basic components – Training, Equipment Procurement and Maintenance, and Levee Patrols.

B.2.1 Component I – Training
All participants will complete the following training to become qualified for levee patrol.

Classroom (3 hours)
• Basic levee design
• Recognizing potential problem characteristics
• Notification/warning system
ARFCD Flood Safety Plan – Appendix B 32
January 2018
• Specific levee patrol assignments
• Command structure
• Safety considerations
Practical Training (3 hours)
• Filling and use of sandbags
• Treatment of boils
• Safety precautions
• Visquine wave wash protection
• Freeboard enhancement
Upon completion of both the classroom and practical functions, a member will remain qualified for 12 months from the final date of training. During flood emergency response conditions, it may be infeasible to provide new volunteers with the “Practical” training session. Instead they will be partnered with experienced patrol personnel who will help and instruct them.

B.2.2 Component II – Equipment Procurement and Maintenance The Sacramento County and the District have a responsibility to ensure the following equipment is staged in an approved location and is in serviceable condition. The following resources, resource lists, and locations shall be maintained by the listed agencies.

ARFCD Office Building
(20) Three-cell watertight flashlights (4) 500-watt lights (60) ‘D’ cell batteries (2) Light standards
(10) CAL-OSHA approved hardhats (8) Propane lanterns
(20) Flat-tipped shovels (4) Portable radios
(10) Sets of assorted size raingear (200) Orange wire marking flags (20,000) Empty sandbags (200) Yellow wire marking flags (2) Generators 3,500 KW or larger (200) Red wire marking flags Sacramento County Fire Department
(20) Watertight flashlights (20) Orange vests
(80) ‘D’ cell batteries (10) Portable radios
(26) US Coast Guard approved lifejackets (10) GPS Units (25) CAL-OSHA approved hardhats (2) Vehicles with mobile radios (6) Flat-tipped shovels (1) Base radio
ARFCD Flood Safety Plan – Appendix B 33
January 2018
B.2.3 Component III – Levee Patrols
• The District Superintendent will create routes that ensure complete coverage, and wherever possible, overlapping coverage.
• The District Superintendent will physically account for all personnel working under their control on an hourly basis.
• All members will receive a safety briefing prior to commencing patrols and will use all provided safety gear.

B.2.3.1 Motor Patrols
• The levee motor patrol will consist of the following:
o Multiple four-wheel drive vehicles with mobile radio capabilities. o Two trained and currently qualified observers per vehicle. o Patrol areas will be divided as shown on the attached map. o Patrol crews will be rotated on a 12-hour frequency.
o Completion of a Patrol Log and/or Division Activity Log will be required for each shiftusing ICS Form 214.
o All members will receive a safety briefing and utilize appropriate safety gear.

B.2.3.2 Walking Patrol
A levee walking patrol will be enforced, as necessary:
• Teams of two personnel physically walking a designated section of levee. One person will be positioned at the toe of the land side of the levee. The second will be assigned to the top of the levee.
• Foot patrols will check visually for potential problems with the levee as per training. • Areas of concern will be identified and tagged.
• All tags will be evaluated by the District Superintendent conducting motor patrol activities. Flags will be used to designate the levee’s condition. When a potential problem is identified, the condition will be reported to Command for an immediate evaluation by the Engineer.
• All levee foot patrol personnel will have the following at a minimum:
o Three-cell watertight flashlight
o Cal OSHA-approved hardhat
o Raingear, if warranted; each individual is responsible for boots o Reflective vest
o (10) Flags
o Global Positioning System (GPS) unit to establish latitude and longitude of trouble sites
o U. S. Coast Guard-approved lifejacket
o One member of each foot-patrol team will be equipped with a portable radio.

Radio communication should be minimized to prevent channel overload. All radio communication will be conducted in plain English, with no jargon or acronyms.

ARFCD Flood Safety Plan – Appendix B 34
January 2018
• Walking patrol personnel will be rotated on an as needed basis.

B.2.4 High Water Staking Procedures
• High water staking: Record the extent of high water by placing markers (stakes) periodically as the event progresses
• Reference those high water locations with suitable surveying or GPS locations • Provide that information to the jurisdiction and DWR upon request B.3 Augmenting Staff
When local personnel resources are depleted or reasonably committed, mutual aid is requested and coordinated within the Operational Area (OA). If OA resources are not sufficient or timely, the request is then forwarded to the Cal EMA Regional Emergency Operations Center (REOC).

The REOC evaluates and fills requests by (a) staff from unaffected OAs, (b) tasking a State agency, or (c) accessing federal assistance. (see Appendix C, Section 4 for Procedures. ) ARFCD Flood Safety Plan – Appendix C 35
January 2018
Appendix C Flood Fight
C.1 Trigger(s)
At the River Warning Stage or upon notification of a potential problem by a levee patrol, establish necessary staging areas for supplies, equipment, and personnel. ARFCD has ensured the staging areas are a safe distance from other emergency facilities, such as evacuation centers, shelters, and Incident Command Posts. If required by the situation, commence filling sandbags.

C.2 Prioritization
ARFCD will use available resources and personnel to address boils, rising water/loss of freeboard, slumps, and sloughs to the full extent of its training and capability.

Based on input from levee patrols and other informed observers, the Sacramento County EOC establishes a Unified Command to set priorities for flood fight operations. All Incident Commanders conduct an Initial Unified Command Meeting. This meeting provides responsible agency officials with an opportunity to discuss and concur on important issues prior to joint incident action planning. The agenda for the command meeting includes the following:
• Set jurisdictional/agency priorities and objectives
• Present jurisdictional limitations, concerns, and restrictions • Develop a collective set of incident objectives
• Establish and agree on acceptable priorities
• Adopt the overall strategy or strategies to accomplish objectives • Agree on the basic organization structure
• Designate the most qualified and acceptable Operations Section Chief (the Operations Section Chief will normally be from the jurisdiction or agency that has the greatest involvement in the incident, although that is not essential) • Agree on General Staff personnel designations and planning, logistics, and finance agreements and procedures
• Agree on the resource ordering process to be followed and cost-sharing procedures • Agree on informational matters, designating one official to act as the Unified Command spokesperson
The members of the Unified Command must be authorized to decide and act on behalf of the jurisdiction or agency they represent. Such decisions/actions may include ordering of additional resources in support of the Incident Action Plan, possible loaning or sharing of resources to other jurisdictions, and agreeing to financial cost-sharing arrangements with participating agencies.

C.3 Activation and Dispatch
The General Manager of ARFCD has the authority to activate this Appendix. Dispatch of Flood Fight Teams shall be in accordance with priorities set by the General Manager.

ARFCD Flood Safety Plan – Appendix C 36
January 2018
C.4 Personnel
ARFCD maintains a cadre of emergency responders. Additional flood emergency response staffing comes from other ARFCD employees and from volunteers.

When the ARFCD requires additional people for sand bagging, emergency debris clearance, diking, and similar activities to save life and protect public safety, assistance may come from trained crews to augment local personnel. In accordance with SEMS, when local resources are depleted or reasonably committed, mutual aid is requested and coordinated within the Sacramento County Operational Area (OA). If OA resources are not sufficient or timely, the request is then forwarded to the REOC. The REOC evaluates and fills requests by coordinating mutual aid from unaffected OAs, tasking a State agency, or accessing federal assistance. Due to the nature of the need and the resource, requests for hand crews are usually tasked to a State agency.

C.4.1 Resource Agencies
The California Conservation Corps (CCC) has trained civilian crews. The California Department of Forestry and Fire Protection (Cal Fire) supervises crews from the California Department of Corrections and California Youth Authority. The California National Guard (CNG) also has personnel available. Both CCC and Cal Fire have contract services for various types of projects.

CNG is only available through State tasking. In addition to crews, CNG and Cal Fire have mobile kitchens and similar support resources available. Cal Fire can also provide trained section leaders for ICS and SEMS organizations.

C.4.2 Mission Tasking
Cal EMA controls missions and mission assignments for State resources and coordinates requests for federal resources. If Cal EMA receives a request for crews that meets the criteria for State agency tasking and if an agency has the capability, Cal EMA will issue a mission number authorizing the agency to respond. Once tasked, that agency will work directly with the requesting agency and provide the resource within the definition and limits of the mission authorization.

C.4.3 Tasking Criteria
For all missions (a) there must be actual or imminent danger to life or public safety, and (b) locally available resources, including private sector contracting, must be inadequate or untimely.

Maintenance or recovery activities should be dealt with by contract and will not be authorized by Cal EMA. Ex Post Facto mission numbers will not be authorized unless it can be clearly demonstrated that properly coordinating the request would have caused an inordinate delay and that such delay would have resulted in severe injury or loss of life.

C.4.4 Costs/Reimbursement
State agencies tasked under a Cal EMA mission number respond free of charge. Crews may require feeding and sheltering; transport vehicles may require gas and maintenance. These services are usually paid for or provided by the requesting agency unless otherwise agreed to at the time of the request.

ARFCD Flood Safety Plan – Appendix C 37
January 2018
C.4.5 Request Procedures
Following coordination within the Sacramento County OA, the EOC will forward unfilled requests to the Inland REOC Operations Section. The REOC will follow up with the Sacramento County OA EOC to resolve any questions and to monitor resource delivery. • Requests should be completed using the Response Information Management System (RIMS) on a RIMS Mission Request/Tasking form. If RIMS is unavailable, hard copy of the form should be faxed to the Inland REOC via the State Warning Center. If faxing is infeasible, phone in the request using the RIMS format. All requests made by RIMS or fax must be confirmed by phone.
• Requests must contain a clear description of the mission to be performed and the number of personnel needed.
• Requests must not specify the agency from which the crew is being requested (i.e., three California Conservation Corps crews). This allows Cal EMA to make mission tasking based upon availability and need, and avoids over-tasking of a single agency. If there are operational reasons to specify an agency, please explain them in the mission statement of the request form.
• The Sacramento County OA EOC must take special care not to duplicate requests with any possibly made via another Mutual Aid System. Accordingly, EOC Branches must coordinate their requests closely. In particular, crews for flood fight should not be requested via Fire Mutual Aid channels (see below).

C.4.6 Fire Mutual Aid
Unlike procedures for other types of emergencies, crews supervised by Cal Fire for flood fight are not accessible under the Fire and Rescue Mutual Aid Plan. All requests for crews for flood fight must follow emergency services channels, regardless of the requesting agency. In view of the natural tendency for requests made by fire agencies to remain in fire channels, it is critical that the Sacramento County OA Region Fire Branch coordinator and the Sacramento County OA Construction and Engineering Branch coordinator communicate closely to avoid confusion and delay.

C.4.7 State Agency Voluntary Response
During non-emergency conditions or non-proclaimed emergencies, State agencies may respond to requests as a locally available resource. Such responses do not receive mission numbers and may not be covered under Mutual Aid and provisions of the Emergency Services Act. Further, all costs are born by the State agency and/or the requesting agency pursuant to any agreement or understanding between them. Resources committed under such responses may be redirected to higher priority missions during emergencies.

C.5 Hazardous Materials Locations
The following sites as having hazardous chemicals stored onsite.

ARFCD Flood Safety Plan – Appendix C 38
January 2018
ARFCD Flood Safety Plan – Appendix C 39
January 2018
C.6 Materials and Supplies

Personnel from ARFCD participate in DWR Flood Fight training, which DWR provides annually. Also, see the DWR Flood Fight Manual:
http://www.water.ca.gov/floodmgmt/docs/flood_fight_methods.pdf C.8 Utilities
In general, coordination with utilities will be the responsibility of the OA EOC. When on-scene coordination is needed, the Utility Representative becomes part of the IC’s staff. In principal, the Utility Representative gives advice to the IC; in practice the Representative often works directly with the Operations Section Chief.

FOR: SAFCA Encroachment
SUBJECT: American River North Levee System Framework for Encroachment Remediation Plan
Introduction and Purpose
An evaluation of encroachments present along the American River North Levee System was performed by Mead & Hunt and MBK Engineers (MBK) in 2024, as a requirement to meet California Department of Water Resources’ (DWR) Urban Levee Design Criteria (ULDC) (DWR, 2012); and to make an Urban Level of Flood Protection (ULOP) Finding that the Sacramento Area Flood Control Agency (SAFCA) levees provide protection against a flood that has a 1-in-200 chance of occurring in any given year. The encroachment evaluation follows requirements set forth in ULDC Section 7.12, Encroachments (Excluding Penetrations, Closure Structures, and Levee Vegetation, which are covered under separate cover if applicable).

MBK prepared a memorandum entitled “SAFCA ULDC Certification Encroachment Evaluation Rationale”, dated December 2023. This memorandum contains the background and methodology used to provide each encroachment with a hazard ranking. This document is included in Appendix A.

Evaluation
Mead & Hunt evaluated and provided a hazard ranking for each of the encroachments along the American River North Levee System, with input from MBK. This evaluation identified there were no high hazard encroachments present along the American River North Levee System. The evaluation identified all encroachments as either moderate or low hazards, as defined in Table 1.

ARNL September 24, 2024
Framework for Encroachment Remediation Plan Page 2
Table 1. Hazard Category Definitions and Corresponding Actions Hazard Category Definition Action
High Hazard Imminent threat to integrity of the levee Immediate remediation required for levee certification
Moderate Hazard
Potential for threat to integrity of levee
in future; impedes operation and
maintenance
Hazard shall be remediated
within 3-5 years, no impact to
levee certification
Low Hazard
Encroachment does not pose a hazard
to the O&M procedures, flood fighting,
or structural integrity of the levee, but is
not permitted and/or corrective action
is required to comply with Title 23.

Hazard shall be remediated
prior to the next levee
certification (10-20 years)
For a ULDC Finding, an evaluation of encroachments within a levee embankment and any adjacent flood control easement(s) is required to meet the following objectives:

1. Determine the permit status of the encroachments.

2. The encroachments must comply with California Code of Regulations Title 23.

3. The encroachment does not adversely impact the structural integrity of the levee during high-water conditions.

4. The encroachment does not adversely affect or impede Local Maintaining Agency (LMA) activities and/or protocol to properly operate and maintain the levee at all times, and to perform the necessary flood fighting techniques during high-water conditions.

This plan framework below outlines next steps that shall be taken to remediate these encroachments.

To fulfill the plan requirements, a detailed list of the encroachments and a timeframe to address the objectives above will need to be added.

Remediation Plan
Coordination between the land use agencies, the LMAs, and the Central Valley Flood Protection Board (CVFPB) will be necessary to meet the Plan’s objectives for remediating the hazardous and noncompliant encroachments before the next recertification process to the greatest extent practicable. The following steps outline a process to meet these objectives:

Step 1: This Plan shall be adopted by the land use agencies (i.e., the City and County) to ensure corrective actions outlined in the steps below are enacted with a prescribed schedule.

Step 2: Determine the permit status of the encroachments. This will include research and communication with CVFPB to locate all available permits. Documentation of each encroachment and the associated permit status shall be tracked and permits collected.

ARNL September 24, 2024
Framework for Encroachment Remediation Plan Page 3
The evaluation shall comply with the ULDC guidelines for encroachments, as follows:
• All existing encroachments are to be authorized by the agency responsible for permitting encroachments along the levee (or floodwall), or removed. • Operation and maintenance of the encroachment shall comply with the conditions required by the approved permit application.

The permit status of encroachments will directly inform the land use agencies and LMA’s whether certain encroachments shall be considered as Moderate Hazard or Low Hazard and the methods and resources in bringing the encroachments into compliance. A target time frame to complete this is 3-to-6 months from adoption of the plan.

Step 3: Confirm the encroachments comply with California Code of Regulations Title 23. This task will involve reviewing the permit documentation, including design and construction details. i. The review should ensure the encroachments do not adversely impact the structural integrity of the levee during high-water conditions.
ii. The review should confirm the encroachments do not adversely affect or impede LMA activities and/or protocol to properly operate and maintain the levee at all times, and to perform the necessary flood fighting techniques during high-water conditions.
iii. A target time frame to complete this is substantial completion within 6-to-12 months after completion of Step 2.

Step 4: For all encroachments missing a CVFPB permit and/or not in compliance with Title 23, identified in Steps 2 and 3, the land use agency will reach out to CVFPB and request corrective actions be taken. The corrective action will require:
• Working with CVFPB on items such as: providing guidance to property owners regarding submitting encroachment permit applications to the CVFPB. • Removal, repair, and/or relocation of the encroachment. • Establishing easement boundaries to mitigate future installations of unpermitted encroachments.
• Creating a timeline for the identified encroachments to come into compliance.

A schedule will be developed as part of this step in coordination with the tracking lists of encroachments identified in Steps 2 and 3 that require future remediation. These requests should be made within 1 year of completion of Step 3.

As outlined in ULDC: “To the extent allowable by law, this plan needs to address eventual removal or permitting of all such encroachments. In some cases, permits may need to provide for access by qualified officials. The city or county must work with the levee maintaining agency and the entity responsible for issuing encroachment permits to establish, document, and publicize a realistic target schedule for implementation of this plan. An example target schedule would be to remove or permit 50 ARNL September 24, 2024
Framework for Encroachment Remediation Plan Page 4
percent of the currently noncompliant encroachments within 5 years and to address the remaining 50 percent in the subsequent 5 years.”
This process may be lengthy to complete depending on the quantity and severity of the compliance issues. A ranking of priority shall be made to manage the remediation of encroachments (i.e., worst first) at which time a target schedule to address unpermitted and non-compliant encroachments shall be developed.

Step 5: The prepared schedule and tracking list shall be revisited and updated by the Land Use Agency at a minimum of every 5 years, with updates attached to the ULDC Engineer’s Report.

Closing
The encroachment remediation plan is a requirement of ULDC Section 7.12 that is needed to meet ULDC as part of SAFCA’s levee certification. The conclusions from the ULDC evaluation are necessary for the Land Use Agency to make an ULOP Finding that the levee system provides protection against a flood that has a 1-in-200 chance of occurring in any given year.

The Land Use Agency shall take this framework and create an Encroachment Remediation Implementation Plan which shall be adopted, followed, and updated on a 5-year basis.

Background
Encroachments are defined in the ULDC as any obstruction or physical intrusion by construction of works or devices, planting or removal of vegetation, or by whatever means for any purpose, into any of the following:
• Any flood control project works
• The waterway area of the project
• The area covered by an adopted plan of flood control
• Any area outside the above limits, if the encroachment could affect any of the above (Title 23 CCE, Division 1, Chapter 1, Article 2, Section 4)
Encroachments on levee embankments require permits issued by the Central Valley Flood Protection Board (CVFPB or Board) and the United States Army Corps of Engineers (USACE). It is common to discover several encroachments along the levees that are either unpermitted or which do not adhere to the original intent and/or conditions of the permit. Over time, very few corrective actions have been taken by enforcement agencies regarding these unpermitted and non-compliant encroachments due to a lack of resources and limited legal recourse.

Encroachments within the flood control right-of-way in the Sacramento area are tracked by DWR, USACE, and LMAs. Regular review of these encroachments is necessary for levee certification, in order to ensure compliance with Title 23, and to determine whether the encroachments adversely impact levee integrity and/or operation and maintenance (O&M) activities.

Methodology
The following methodology was developed to evaluate existing encroachments in SAFCA levee systems and to form the basis for the Finding:
• Collect essential information for each existing encroachment • Evaluate the encroachments based on their impact to levee integrity and/or O&M MBK Engineers September 27, 2024
SAFCA ULDC Certification Encroachment Evaluation Rationale Page 3 • Prepare an Encroachment Remediation Plan to address non-compliant and potentially hazardous encroachments on levee embankments
Step 1: Data Collection
Encroachments within the levee embankment and existing/future right-of-way (i.e., up to 20 feet from levee toe) shall be field verified for each levee system using GPS equipment and highresolution cameras. At a minimum, the types and locations of the encroachments will be recorded in a database that can be summarized for evaluation. Additional details for the encroachments can be captured and recorded during the data collection process, as necessary to support corrective action.

Step 2: Encroachment Data Evaluation
MBK will review and evaluate the existing encroachments in accordance with the following key procedures as outlined in ULDC Section 7.12 (in italics):
i. Initial Assessment
• The civil engineer needs to assess existing encroachments 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 HTOL1
.
• The opinion needs to consider all encroachments within the channel, on the levee, and within the landside right-of-way identified in Section 7.11, irrespective of whether the property rights have been acquired.

For each levee system, the Certification Team will evaluate specific types of encroachments that may affect levee performance during high-water conditions. MBK will have engaged with the associated Local Maintaining Agencies to discuss encroachments that hamper O&M activities. The database inventory of encroachments, and the analysis tools available in the database, will inform the initial assessment of existing encroachments that may potentially cause severe damage to the levee or inhibit O&M monitoring or flood fighting.
ii. Engineering Judgment
• Due to the limitations of analytical tools for assessing the impacts of encroachments, the civil engineer needs to exercise sound engineering judgment in rendering this opinion. • The civil engineer shall consider the following when rendering this opinion: type, age, condition, performance history of the encroachment, and 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.

In cases where the existing encroachment is outside the levee minimum geometry and visibility right-of-way, sound engineering judgment may replace the detailed geotechnical and hydraulic analyses.

MBK Engineers September 27, 2024
SAFCA ULDC Certification Encroachment Evaluation Rationale Page 4 Each levee system will undergo a screening process to properly exercise the appropriate level of engineering judgment that shall include, but not be limited to:
• Identifying common encroachment types that exist
• The proximity of similar encroachments (i.e., common among adjacent properties) • Review of existing geotechnical evaluations for slope stability and seepage mitigation • Review existing levee geometry (i.e., standard vs. wide levee) iii. Hazard Assessment
• A hazard assessment needs to be performed for each existing encroachment, whether permitted or not. Encroachments with a potential to be a high hazard need to have a full engineering evaluation, to demonstrate that the hazard is acceptable, or be removed or modified.
• All existing encroachments considered a high hazard are to be removed or modified to restore the reliability of the levee/floodwall. Encroachment removal or modification shall be performed under the direction of a civil engineer and should address, at a minimum, seepage and slope stability issues and the structural integrity of the levee. In addition, the encroachment removal or modification must not significantly diminish hydraulic capacity of the channel or hinder operations and maintenance. A proposed removal or modification plan is to be approved by the levee maintaining agency and the Board (for levees regulated by the Board).

Based on input from others and on MBK’s experience, the following encroachment types (in alphabetical order) may potentially be identified as hazardous and will require a more focused review. The following descriptions include a brief statement of the impact to the levee:
• Bike trail alignment – obstruction for O&M
• Bridges – obstruction for O&M, scour around abutment
• Gates across levees – key availability, opening of gate (standard operating procedure(s) [SOP]), alternative access routes
• Landscaping on the levee slope and at the landside toe – also covered under ULDC 7.16 Levee Vegetation (impedes visibility for flood fighting) • Poles – obstruction for O&M, penetration of blanket, and seepage exit point • Pressurized pipes, including irrigation piping, within the levee slope and parallel to landside toe – obstruction for O&M, potential to rupture below grade, and scour embankment • Retaining walls – stability of levee, impedes visibility for flood fighting, obstruction for O&M, engineering analysis
• Stairways – obstruction for O&M, stability of levee
MBK Engineers September 27, 2024
SAFCA ULDC Certification Encroachment Evaluation Rationale Page 5 • Structures – excluding residential (impeded visibility for flood fighting) To execute a consistent methodology in evaluating the encroachments for all levee systems, a series of flow charts, one chart for each of the aforementioned encroachment types, has been prepared and is included as Attachment 1. These flow charts include the rationale followed to assign a hazard category to each encroachment, and is based on the type and condition of each encroachment, thus providing an overall evaluation of the encroachments as required to meet the Urban Level of Flood Protection. The hazard categories are defined as follows:

Table 1. Hazard Category Definitions and Corresponding Actions Hazard Category Definition Action
High Hazard Imminent threat to integrity of the
levee.

Immediate remediation
required for levee
certification.

Moderate Hazard
Potential for threat to integrity of
levee in future; impedes operation
and maintenance.

Hazard shall be
remediated within 3-5
years, no impact to
levee certification.

Low Hazard
Encroachment does not pose a
hazard to the O&M procedures,
flood fighting, or structural
integrity of the levee, but is not
permitted and/or corrective action
is required to comply with Title 23.

Hazard shall be
remediated prior to the
next levee certification
(10-20 years).

High Hazard Encroachments are an immediate and imminent threat to levee integrity, and therefore would preclude ULDC certification until corrective actions take place. An engineering evaluation shall be performed to assess the need for removal, remediation, or leaving in place. The engineering evaluation shall include a review of “seepage and slope stability issues and the structural integrity of the levee” (ULDC Section 7.12, DWR, 2012). An example of a high hazard encroachment includes a failing retaining wall within the embankment zone of a standard size levee.

Moderate Hazard Encroachments may potentially have an adverse impact on levee integrity while significantly impeding LMAs from operating, maintaining, or flood fighting the levee. Engineering judgment and feedback from the LMA will inform whether an encroachment is moderately hazardous and if corrective actions are required in 5 years or less from when the ULDC Finding is made. Examples of a moderate hazard encroachments include non-compliant dense vegetation and sprinkler systems on the levee slope.

Low Hazard Encroachments are determined to not meet ULDC if they either (1) have not been permitted or (2) interfere with operation, maintenance, or flood fight capability. Typically, unpermitted encroachments on the levee are installed by the adjacent homeowners as an extended MBK Engineers September 27, 2024
SAFCA ULDC Certification Encroachment Evaluation Rationale Page 6 feature of their property onto the levee regardless of prescriptive rights or underlying property ownership.
iv. Status of Encroachment Permits
The encroachment evaluation includes an overview of the permit status of all known and visible encroachments for each levee system. Permitted encroachments shall be Title 23 compliant to ensure levee integrity and operations are not affected. Permitted encroachments signify that the CVFPB and USACE have provided the necessary reviews to allow encroachments to be constructed and installed within the levee embankment and adjacent rights-of-way. The evaluation shall comply with the ULDC guidelines for encroachments, as follows:
• All existing encroachments are to be authorized by the agency responsible for permitting encroachments along the levee (or floodwall), or removed. • Operation and maintenance of the encroachment shall comply with the conditions required by the approved permit application.

The permit status of encroachments will directly inform the Certification Team whether certain encroachments shall be considered as Moderate Hazard or Low Hazard and the methods in bringing the encroachments into compliance.

Step 3: Preparing the Encroachment Remediation Plan
For Moderate and Low Hazard encroachments, an Encroachment Remediation Plan (Plan) shall be prepared that will outline the necessary actions to resolve and/or remediate individual encroachments. The Plan shall include steps to take corrective actions based on the severity of the encroachments, such as providing guidance to property owners regarding submitting encroachment permit applications to the CVFPB, removal and/or relocation of the encroachment, establishing easement boundaries to mitigate future installations of unpermitted encroachments, and creating a timeline for the identified encroachments to come into compliance. In order to achieve the Plan’s objectives, the Plan shall be adopted by the land use agencies (i.e., the City and County) to ensure corrective actions are enacted with a prescribed schedule. Coordination between the land use agencies, the LMAs, and the CVFPB will be necessary to meet the Plan’s objectives for remediating the hazardous encroachments before the next recertification process to the greatest extent practicable.

Conclusion
A list of encroachments will be provided in supporting documentation to the ULDC Engineer’s Report, prepared by the Certification Team. If a Plan is required, the Plan will be an attachment to the ULDC Engineer’s Report. High Hazard encroachments will be included and discussed in the ULDC Engineer’s Report for the purpose of tracking and documenting the plan.

1 1.1 Background and Purpose
This report is part of 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 American North Levee System (ANLS), prepared in response to the regulatory requirements of ULDC. Preparation of this report entailed gathering information related to the ANLS, 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 ANLS 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 ANLS protects an urban population, these ULDC criteria were used to assess the levee’s compliance and the due diligence of SAFCA.

Mead & Hunt is a member of SAFCA’s consultant team and 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 ANLS is located in the North Sacramento Streams and American River Levee groups.
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 ANLS 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 (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 ANLS was included. That effort is documented in (Mead & Hunt, Inc., 2015). • A visual inspection of the ANLS was conducted in December 2023 and levee encroachments, penetrations, floodwalls, retaining walls, and closure structures database information were assessed and revised accordingly. Applicable analyses and assessments were conducted, as discussed in this report.
• 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 o City Of Sacramento, Department of Utilities – Water
o Sacramento County, Water Resources Drainage Division
o Sac Sewer (Sacramento Regional Sanitation District/Sacramento Area Sewer District) o PG&E natural gas
o Kinder Morgan Pipeline
• Review of annual trial exercise of emergency closure gate programs with the City stormwater and County drainage 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 and Del Paso Floodgate trial closures, witnessed by Mead & Hunt. • Review and evaluation of whether the ANLS 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 3 ULDC criteria. It is intended to serve as a supplement to the previously documented Mead & Hunt analyses and reports, mentioned previously.

1.3 Report Organization
This report is divided into seven sections. Section 1 is an introductory section that describes the background, need and 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 ANLS 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 (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, and 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 need for 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 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 (Sacramento FEMA Certification White Paper for Addressing Encroachments, 2014) that included criteria based upon FEMA and ULDC Criteria to be adopted for 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 LMAs 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 upon technical evaluations and compliance with criteria that is 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 (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 (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
This due diligence review included a field investigation conducted in December 2023 (by Mead & Hunt and MBK) and encroachment data was verified during this time. The total number of encroachments for this levee system is 593 (of which 47 are linear encroachments), which 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 ANLS encroachments.

Additionally, Exhibits 3A1 and 3A2 show a table summary of all ANLS encroachments and linear encroachments, respectively. During the December 2023 field investigations and review of existing data, no high-risk encroachments were flagged for ANLS by Mead & Hunt. This was further confirmed by MBK.

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.

2.5 Due Diligence Review; ULDC and FEMA Compliance
In 2013 and 2014, SAFCA performed an inventory of encroachments along the ANLS (Mead & Hunt, Inc., 2015). A hazard assessment of the encroachments was performed using established criteria in the encroachment white paper (Sacramento FEMA Certification White Paper for Addressing Encroachments, 2014). 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 December 2023. The total number of encroachments for this levee system is 593, 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 on-permitted encroachments. In summary, there are no high-risk encroachments along the ANLS. Mead & Hunt has confirmed with MBK that the ANLS 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 was 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).”
FEMA 44 CFR 65.10(b)(2) provides criteria for assessment of closure structures which include the gravity drains along the levee that provide hydraulic connectivity between the flooding source and the levee impacted area. 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, as well as 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 that were 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 ANLS 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 ANLS and 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, 245 penetrations were reviewed, screened, and analyzed, as appropriate and the database was updated based upon previous methodology. A map summary and table summary of the penetrations and associated structures is included in this report as Exhibits 2B and 3B, respectively. Since our previous efforts, 38 penetrations have required further analysis that previously did not due to age, design water surface elevation changes, new work, or other factors. 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 ANLS that were determined (during the screening process) to require a full engineering evaluation to make a final determination of acceptability based upon 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 ANLS 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 ANLS’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 ANLS 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 closure structure, retaining wall, and floodwall strength and stability analysis was based on the same criteria as 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 Del Paso flood and the UPRR stoplog 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 Del Paso Boulevard Flood Gate and the UPRR stoplog closure in the American River North Levee are part of the line of protection constructed by the USACE as part of the 1950’s federal project and are not separately permitted and is documented in the levee operation and maintenance manual. The UPRR stoplog closure in the Arcade Creek South Levee was original constructed under CVFPB permit 14479, and modifications were implemented under permit 16032. 10 closure structures as these facilities provide hydraulic connectivity between the flooding source and the levee impacted area. 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.”

4.3 Methodology
The closure structure, retaining wall, and floodwall 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 by 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 ANLS 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 December 2023. The trial installations of the three (3) closure structure installations in the ANLS have been overseen by Mead & Hunt (in accordance with the agreed upon City of Sacramento trial closure schedule), and no issues were found.

One ANLS floodwall is located adjacent to the north and south abutments of the bridge crossing for West El Camino Avenue over the NEMDC. The existing floodwall and closure structure was removed, and a new floodwall was constructed as part of the (West) El Camino Bridge Replacement Project in 2008 under Permit No. 18175 included in Appendix E1.

The other floodwall is located on the Arcade Creek South Levee (ACSL) on the waterward shoulder of the levee crest between Rio Linda Boulevard and Marysville Boulevard3. A new levee culvert was installed through the floodwall at Station 4076+69 under Permit No. 19449, and the continuity of floodwall was 3 SAFCA Contract 3073, Arcade Creek, Unit 1B Levee Improvement Project, Drawings L-6 thru L-9. 11 restored with a connection to the new cast-in-place concrete positive closure gate shaft. As part of SAFCA’s 2017 North Area Streams Levee Improvement Project, the waterside slope degrade, and reconstruction abutted the floodwall from Rio Linda Boulevard to Belden Street. 4 A field assessment
conducted by Mead & Hunt in December 2023 found no adverse conditions.

Three closure structures are located within the ANLS, which includes one floodgate and two stoplog structures, as follows:
• The flood gate (dual door miter gate) closure for Del Paso Boulevard is operated and maintained by the City of Sacramento Department of Transportation. Rehabilitation of this floodgate has recently been completed, and the plans are included in Appendix E2. During the final inspection of the flood gate rehabilitation work (completed in 2023), Mead & Hunt observed the trial installation of the gate, and the gate was found to be constructed in accordance with the plans and specifications. The gate was in good working order. • There are two UPRR crossing closure structures operated and maintained by the City of Sacramento Department of Transportation. Limited modifications to these floodgates have recently been constructed, and the plans are included in Appendix E1. Additionally, trial closures are conducted once every five years (instead of annually). The recent trial closure report for the following floodgates is included in Appendix E3. An exception TM for annual trial installation for these closure structures is included in Appendix C.
o Arcade Creek South Levee UPRR crossing stoplog structure o Del Paso Boulevard UPRR crossing stoplog structure
A total of 12 retaining walls were identified within the zone of influence of the ANLS levees. Of these 3 retaining walls were identified that required structural evaluation, all within the City/County pump stations at City Sump 159, City Sump 154, and County D-43 Wilhaggin Pump Station.

4.4.1 Analysis Results
No additional analyses were required for the ANLS 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 ACSL and West El Camino bridge floodwalls were field inspected in December 2023 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 three closure structures (Del Paso Boulevard floodgate and UPRR stoplog structures) were 4 SAFCA Contract 4355, North Area Streams Levee Improvement Project, Drawing C304 12 field inspected and found to be acceptable for the intended use 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 2023. 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 E3. 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 ANLS 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 to the reliability of the ANLS’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. The Del Paso Boulevard floodgate trial closures are conducted annually.
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 when added to the median 200-year still water surface elevation, 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 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 ANLS was completed in 2015 and updated in 2023 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 ANLS 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 ANLS 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.

Mead & Hunt also complied with the O&M manuals for the drainage pump stations in ANLS 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 are 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 their roles for system operation.

The O&M manual and operating procedures for the pump stations were reviewed with the City and County 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 ANLS 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 ANLS, Mead & Hunt has concluded that the overall condition of the ANLS has not significantly changed since the ULDC and FEMA certification efforts documented in (Mead & Hunt, Inc., 2015). It is our professional opinion that ANLS 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 E. It is also our professional opinion that ARNL meets FEMA criteria in accordance with 44 CFR 65.10(b)(2) for the gravity drain penetrations, UPRR stoplog closure structures, and the flood gate closure for the Del Paso Road crossing. Other conclusions and recommendations pertaining to the ANLS are discussed below.

7.1 Conclusions
The following conclusions have been made for each area covered in this report.

7.1.1 Encroachments
The previous ULDC and FEMA certification efforts conducted are covered in (Mead & Hunt, Inc., 2015) and no high-risk encroachments were flagged by Mead & Hunt (confirmed by MBK). ANLS is determined to comply with ULDC criteria Section 7.12.

7.1.2 Penetrations
The previous ULDC and FEMA certification efforts conducted are covered in (Mead & Hunt, Inc., 2015) and all current efforts are discussed in this report. ANLS is determined to be in compliance) with ULDC criteria Section 7.13 and FEMA criteria in accordance with 44 CFR 65.10(b)(2), with exceptions. The mitigation plan for finalizing the penetration documentation as described in Appendix E.

7.1.3 Floodwalls, Retaining Walls and Closure Structures The previous ULDC and FEMA certification efforts conducted are covered in (Mead & Hunt, Inc., 2015) and current efforts are discussed in this report. ANLS is determined to be in compliance with ULDC criteria Section 7.14 and FEMA criteria in accordance with 44 CFR 65.10(b)(2), with the inclusion of the ULDC exception for the frequency of trial operation of the UPRR closure structures included in Appendix C.

7.1.4 Wind Setup and Wave Runup
The previous ULDC and FEMA certification efforts conducted are covered in (Mead & Hunt, Inc., 2015) and current efforts are discussed in this report. ANLS is determined to be in compliance with ULDC criteria Section 7.17.

7.1.5 Operation and Maintenance Manuals
The previous ULDC and FEMA certification efforts conducted are covered in (Mead & Hunt, Inc., 2015) and all current efforts are discussed in this report. ANLS is determined to be in compliance with ULDC criteria Section 7.20.
16 7.2 Recommendations
Below is a list of Mead & Hunt’s recommendations for the ANLS. 1) The encroachments, penetrations, floodwalls, retaining walls, and closure structures either discussed in this report or previously reported (Mead & Hunt, Inc., 2015) in the ANLS 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 ANLS with assistance from the CVFPB, if necessary.
3) The mitigation plans for ULDC exceptions, described in Appendix E, should be carried out.

SAFCA should request monthly updates on status of resolution with the responsible parties. 4) The UPRR stoplog closure should continue to be trial operated on a 5-year cycle with annual preparedness conducted in the fall.
5) The ANLS 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 support 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 ANLS, related facilities and their conformance to ULDC criteria is 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 which 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 document performance and condition of penetrations that are anticipated to be at the end of their useful life.
