PROJECT BACKGROUND AND AUTHORIZATION
The American River FCD - Dry Cr, NEMDC, Arcade Cr levee system is a portion of the Sacramento River Flood Control Project (SRFCP). The SRFCP is a large-scale project authorized by the Flood Control Act of 1917 as modified by the Acts of 1928, 1937, and 1941. Additional work on the levee system was authorized by 102nd Congress, H.R. 5504 in Section 9159 of the Department of Defense Appropriations Act of 1993 (Public Law 102-396), approved on October 6, 1992. The following operations and maintenance (O&M) manuals pertain to this levee system:
• Standard O&M Manual for the SRFCP, dated May 1955.
• Supplement to Standard, O&M Manual, SRFCP Unit No. 118 Pt. 2, N. Levee American River, E. Levee Natomas Canal, Both Levees Arcade Creek, S. Levee Linda Creek, & Magpie Creek Diversion Channel, revised January 28, 2023.

waters in Natomas East Canal, Arcade Creek, Linda Creek, and Magpie Creek Diversion Channel. In addition to the urban population, key infrastructure with property values estimated in the billions of dollars are present within the leveed area. The Central Valley Flood Protection Board (CVFPB) and Sacramento Area Flood Control Agency (SAFCA) are the non-Federal sponsors and are the responsible agency for O&M of the levee system. American River Flood Control District (ARFCD) and California Department of Water Resources (CA DWR) performs many O&M activities on behalf of the CVFPB and SAFCA (referred to as the maintaining agency). SPK performed a Risk Assessment on this levee system in 2016, the risk classification was determined to be “high”.
SCOPE OF INSPECTION
A formal levee inspection was performed on the American River FCD - Dry Cr, NEMDC, Arcade Cr levee system located in Del Paso Heights of Sacramento County, California.
The inspection was limited to the congressionally authorized project. The congressionally authorized project does not have interior drainage or pump station features. Table 1 lists the individual levee segment, segment mileage, and the inspection dates.

WEATHER AND RIVER CONDITIONS DURING INSPECTION
The inspection was performed in the winter of 2023. Skies were cloudy with partial rain and the temperatures ranged from a high of 63 and low of 48 degrees Fahrenheit.
Inspection Summary American River FCD - Dry Cr, NEMDC, Arcade Cr
The O&M Manual (2023) for this levee system uses two (2) river gauges to define “flood” or “high water period”. Table 2 summarizes the river stage and flood stage at the two gauges. The river stage is the average water surface elevation of the river at the gauge on the dates of the inspection. The monitor stage is the water surface elevation of the river at the gauge during a "flood" or "high water period”. Vertical elevations are reported in North American Vertical Datum of 1988 (NAVD88). The river stage data was obtained from the California Data Exchange Center (CDEC) website:
https://cdec.water.ca.gov/index.html.

Levee Inspection Summary
Levee Segment Insnection Summary_;_
[Provide an Executive Summary of the segment inspection considering (1) the general condition of the segment, (2) the rationale for key Item ratings, categorized by Feature , and (3) the quantity or severity of notable observations/deficiencies and (4) notable changes in condition since the last inspection.] The inspection team identified unacceptable conditions as part of this inspection. The report card and checklist identify the worst-case item ratings for the American River FCD - Unit 8, Magpie Creek (AR09) levee segment. An engineering determination, based upon visual inspection and supplemental information, concluded there are no unacceptable conditions that are expected to have a negative impact on performance (NIOP). An engineering determination, based upon visual inspection and supplemental information, concluded there are unacceptable conditions that require action but are not expected to have a negative impact on performance in the Vegetation Growth, Erosion/Bank Caving, and Riprap Revetments & Bank Protection Rated Item categories (these observations are rated "Unacceptable" and do not include "NIOP" in the item description). No previous inspection was performed for this segment.
Levee System Insnection Summary_;_
[Synthesize ieformation from the Levee Segment Inspection Summaries for each segment within the levee system. For single-segment levee systems, see Levee Segment Inspection Summary above.]
The inspection team identified unacceptable conditions as part of this inspection. Trees, brush, and thick woody vegetation that were observed along significant portions of the levee embankments. Sod cover was up to 100 percent missing over significant reaches of the levees, with rills often greater than 3 inches observed. Many unauthorized encroachments were observed. There is a significant transient population on or near the levee slopes with tents, furniture, and miscellaneous debris. No video inspection records are available for multiple pipes and utilities crossing the levees. Several large diameter depressions up to 8 inches deep were observed throughout the levee system. Series of ruts over 6 inches were observed on the WS toe patrol road. Observable riprap was in mostly acceptable condition with some minor displacement and obscuration from vegetation.

6. Tilting, Sliding
or Settlement
of Concrete
Structures
NA
A There are no significant areas of tilting, sliding, or settlement that would endanger the integrity of the structure.
M There are areas of tilting, sliding, or settlement (either active or inactive) that need to be repaired. The maximum offset, either laterally or vertically, does not exceed 2 inches unless the movement can be shown to be no longer actively occurring. The integrity of the structure is not in danger.
U There are areas of tilting, sliding, or settlement (either active or inactive) that threaten the structure's integrity and performance. Any movement that has resulted in failure of the waterstop (possibly identified by daylight visible through the joint) is unacceptable. Differential movement of greater than 2 inches between any two adjacent monoliths, either laterally or vertically, is unacceptable unless it can be shown that the movement is no longer active. Also, if the floodwall is of I-wall construction, then any visible or measurable tilting of the wall toward the protected side that has created an open horizontal crack on the riverside base of a monolith is unacceptable.
NA There are no concrete items in the channel.

7. Foundation of
Concrete
Structures
NA
A No active erosion, scouring, or bank caving that might endanger the structure's stability.
M There are areas where the ground is eroding towards the base of the structure. Efforts need to be taken to slow and repair this erosion, but it is not judged to be close enough to the structure or to be progressing rapidly enough to affect structural stability before the next inspection. For the purposes of inspection, the erosion or scour is not closer to the riverside face of the wall than twice the floodwall's underground base width if the wall is of L-wall or T-wall construction; or if the wall is of sheetpile or I-wall construction, the erosion is not closer than twice the wall's visible height.
Additionally, rate of erosion is such that the wall is expected to remain stable until the next inspection.
U Erosion or bank caving observed that is closer to the wall than the limits described above, or is outside these limits but may lead to structural instabilities before the next inspection. Additionally, if the floodwall is of Iwall or sheetpile construction, the foundation is unacceptable if any turf, soil or pavement material got washed away from the landside of the I-wall as the result of a previous overtopping event.
NA There are no concrete items in the channel.
8. Slab and
Monolith Joints NA
A The joint material is in good condition. The exterior joint sealant is intact and cracking / desiccation is minimal. Joint filler material and/or waterstop is not visible at any point.
M The joint material has appreciable deterioration to the point where joint filler material and/or waterstop is visible in some locations. This needs to be repaired or replaced to prevent spalling and cracking during freeze / thaw cycles, and to ensure water tightness of the joint.
U The joint material is severely deteriorated or the concrete adjacent to the monolith joints has spalled and cracked, damaging the waterstop; in either case, damage has occurred to the point where it is apparent that the joint is no longer watertight and will not provide the intended level of protection during a flood.

Levee Inspection Summary
Levee Segment Insnection Summary_;_
[Provide an Executive Summary of the segment inspection considering (1) the general condition of the segment, (2) the rationale for key Item ratings, categorized by Feature , and (3) the quantity or severity of notable observations/deficiencies and (4) notable changes in condition since the last inspection.] The inspection team identified unacceptable conditions as part of this inspection. The report card and checklist identify the worst-case item ratings for the American River FCD - Units 6 and 8, Dry Creek left bank (AR06) levee segment. An engineering determination, based upon visual inspection and supplemental information, concluded there are no unacceptable conditions that are expected to have a negative impact on performance (NIOP). An engineering determination, based upon visual inspection and supplemental information, concluded there are unacceptable conditions that require action but are not expected to have a negative impact on performance in the Vegetation Growth, Depressions/Rutting, and Slope Stability Rated Item categories (these observations are rated "Unacceptable" and do not include "NIOP" in the item description). USACE last performed an inspection of this levee segment in 2009.
Levee System Insnection Summary_;_
[Synthesize ieformation from the Levee Segment Inspection Summaries for each segment within the levee system. For single-segment levee systems, see Levee Segment Inspection Summary above.]
The inspection team identified unacceptable conditions as part of this inspection. Trees, brush, and thick woody vegetation that were observed along significant portions of the levee embankments. Sod cover was up to 100 percent missing over significant reaches of the levees, with rills often greater than 3 inches observed. Many unauthorized encroachments were observed. There is a significant transient population on or near the levee slopes with tents, furniture, and miscellaneous debris. No video inspection records are available for multiple pipes and utilities crossing the levees. Several large diameter depressions up to 8 inches deep were observed throughout the levee system. Series of ruts over 6 inches were observed on the WS toe patrol road. Observable riprap was in mostly acceptable condition with some minor displacement and obscuration from vegetation.

1. Unwanted
Vegetation
Growth
M
A The levee has little or no unwanted vegetation (trees, bush, or undesirable weeds), except for vegetation that is properly contained and/or situated on overbuilt sections, such that the mandatory 3-foot root-free zone is preserved around the levee profile. The levee has been recently mowed. The vegetation-free zone extends 15 feet from both the landside and riverside toes of the levee to the centerline of the tree. If the levee access easement doesn't extend to the described limits, then the vegetation-free zone must be maintained to the easement limits. Reference EP 1110-2-18 and other relevant Corps policy.
M Minimal vegetation growth (brush, weeds, or trees 2 inches in diameter or smaller) is present within the zones described above. This vegetation must be removed but does not currently threaten the operation or integrity of the levee.
U Significant vegetation growth (brush, weeds, or any trees greater than 2 inches in diameter) is present within the zones described above and must be removed to reestablish or ascertain levee integrity.

A There are no significant areas of tilting, sliding, or settlement that would endanger the integrity of the structure.
M There are areas of tilting, sliding, or settlement (either active or inactive) that need to be repaired. The maximum offset, either laterally or vertically, does not exceed 2 inches unless the movement can be shown to be no longer actively occurring. The integrity of the structure is not in danger.
U There are areas of tilting, sliding, or settlement (either active or inactive) that threaten the structure's integrity and performance. Any movement that has resulted in failure of the waterstop (possibly identified by daylight visible through the joint) is unacceptable. Differential movement of greater than 2 inches between any two adjacent monoliths, either laterally or vertically, is unacceptable unless it can be shown that the movement is no longer active. Also, if the floodwall is of I-wall construction, then any visible or measurable tilting of the wall toward the protected side that has created an open horizontal crack on the riverside base of a monolith is unacceptable.
6. Foundation of
Concrete
Structures
A No active erosion, scouring, or bank caving that might endanger the structure's stability.
M There are areas where the ground is eroding towards the base of the structure. Efforts need to be taken to slow and repair this erosion, but it is not judged to be close enough to the structure or to be progressing rapidly enough to affect structural stability before the next inspection. For the purposes of inspection, the erosion or scour is not closer to the riverside face of the wall than twice the floodwall's underground base width if the wall is of L-wall or T-wall construction; or if the wall is of sheetpile or I-wall construction, the erosion is not closer than twice the wall's visible height.
Additionally, rate of erosion is such that the wall is expected to remain stable until the next inspection.
U Erosion or bank caving observed that is closer to the wall than the limits described above, or is outside these limits but may lead to structural instabilities before the next inspection. Additionally, if the floodwall is of Iwall or sheetpile construction, the foundation is unacceptable if any turf, soil or pavement material got washed away from the landside of the I-wall as the result of a previous overtopping event.

Levee Inspection Summary
Levee Segment Inspection Summary:
[Provide an Executive Summary of the segment inspection considering (1) the general condition of the segment, (2) the rationale for key Item ratings, categorized by Feature , and (3) the quantity or severity of notable observations/deficiencies and (4) notable changes in condition since the last inspection.] The inspection team identified unacceptable conditions as part of this inspection. The report card and checklist identify the worst-case item ratings for the American River FCD - Unit 2 north, NEMDC above Arcade Creek (AR2A) levee segment. An engineering determination, based upon visual inspection and supplemental information, concluded there are no unacceptable conditions that are expected to have a negative impact on performance (NIOP). An engineering determination, based upon visual inspection and supplemental information, concluded there are other unacceptable conditions that require action but are not expected to have a negative impact on performance in the Vegetation Growth, Sod Cover, Depressions/Rutting, and Erosion/Bank Caving Rated Item categories (these observations are rated "Unacceptable" and do not include "NIOP" in the item description). USACE last performed an inspection of this levee segment in 2009.
Levee System Inspection Summary:
[Synthesize information from the Levee Segment Inspection Summaries for each segment within the levee system. For single-segment levee systems, see Levee Segment Inspection Summary above.]
The inspection team identified unacceptable conditions as part of this inspection. Trees, brush, and thick woody vegetation that were observed along significant portions of the levee embankments. Sod cover was up to 100 percent missing over significant reaches of the levees, with rills often greater than 3 inches observed. Many unauthorized encroachments were observed. There is a significant transient population on or near the levee slopes with tents, furniture, and miscellaneous debris. No video inspection records are available for multiple pipes and utilities crossing the levees. Several large diameter depressions up to 8 inches deep were observed throughout the levee system. Series of ruts over 6 inches were observed on the WS toe patrol road. Observable riprap was in mostly acceptable condition with some minor displacement and obscuration from vegetation.

Levee Inspection Summary
Levee Segment Inspection Summary:
[Provide an Executive Summary of the segment inspection considering (1) the general condition of the segment, (2) the rationale for key Item ratings, categorized by Feature , and (3) the quantity or severity of notable observations/deficiencies and (4) notable changes in condition since the last inspection.] The inspection team identified unacceptable conditions as part of this inspection. The report card and checklist identify the worst-case item ratings for the American River FCD - Unit 7, Arcade Creek right bank (AR07) levee segment. An engineering determination, based upon visual inspection and supplemental information, concluded there are no unacceptable conditions that are expected to have a negative impact on performance (NIOP). An engineering determination, based upon visual inspection and supplemental information, concluded there are other unacceptable conditions that require action but are not expected to have a negative impact on performance in the Vegetation Growth, Sod Cover, Depressions/Rutting, Slope Stability, Monolith Joints, and Underseepage Relief Wells/Toe Drainage Systems Rated Item categories (these observations are rated "Unacceptable" and do not include "NIOP" in the item description). USACE last performed an inspection of this levee segment in 2009.
Levee System Inspection Summary:
[Synthesize information from the Levee Segment Inspection Summaries for each segment within the levee system. For single-segment levee systems, see Levee Segment Inspection Summary above.]
The inspection team identified unacceptable conditions as part of this inspection. Trees, brush, and thick woody vegetation that were observed along significant portions of the levee embankments. Sod cover was up to 100 percent missing over significant reaches of the levees, with rills often greater than 3 inches observed. Many unauthorized encroachments were observed. There is a significant transient population on or near the levee slopes with tents, furniture, and miscellaneous debris. No video inspection records are available for multiple pipes and utilities crossing the levees. Several large diameter depressions up to 8 inches deep were observed throughout the levee system. Series of ruts over 6 inches were observed on the WS toe patrol road. Observable riprap was in mostly acceptable condition with some minor displacement and obscuration from vegetation.

Vegetation
Growth
M
A The levee has little or no unwanted vegetation (trees, bush, or undesirable weeds), except for vegetation that is properly contained and/or situated on overbuilt sections, such that the mandatory 3-foot root-free zone is preserved around the levee profile. The levee has been recently mowed. The vegetation-free zone extends 15 feet from both the landside and riverside toes of the levee to the centerline of the tree. If the levee access easement doesn't extend to the described limits, then the vegetation-free zone must be maintained to the easement limits. Reference EP 1110-2-18 and other relevant Corps policy.
M Minimal vegetation growth (brush, weeds, or trees 2 inches in diameter or smaller) is present within the zones described above. This vegetation must be removed but does not currently threaten the operation or integrity of the levee.

4. Concrete
Surfaces M
A Negligible spalling, scaling or cracking. If the concrete surface is weathered or holds moisture, it is still satisfactory but should be seal coated to prevent freeze / thaw damage.
M Spalling, scaling, and open cracking present, but the immediate integrity or performance of the structure is not threatened. Reinforcing steel may be exposed. Repairs / sealing is necessary to prevent additional damage during periods of thawing and freezing.
U Surface deterioration or deep cracks present that may result in an unreliable structure. Any surface deterioration that exposes the sheet piling or lies adjacent to monolith joints may indicate underlying reinforcement corrosion and is unacceptable.

5. Tilting, Sliding
or Settlement
of Concrete
Structures
A
A There are no significant areas of tilting, sliding, or settlement that would endanger the integrity of the structure.
M There are areas of tilting, sliding, or settlement (either active or inactive) that need to be repaired. The maximum offset, either laterally or vertically, does not exceed 2 inches unless the movement can be shown to be no longer actively occurring. The integrity of the structure is not in danger.
U There are areas of tilting, sliding, or settlement (either active or inactive) that threaten the structure's integrity and performance. Any movement that has resulted in failure of the waterstop (possibly identified by daylight visible through the joint) is unacceptable. Differential movement of greater than 2 inches between any two adjacent monoliths, either laterally or vertically, is unacceptable unless it can be shown that the movement is no longer active. Also, if the floodwall is of I-wall construction, then any visible or measurable tilting of the wall toward the protected side that has created an open horizontal crack on the riverside base of a monolith is unacceptable.
6. Foundation of
Concrete
Structures
A
A No active erosion, scouring, or bank caving that might endanger the structure's stability.
M There are areas where the ground is eroding towards the base of the structure. Efforts need to be taken to slow and repair this erosion, but it is not judged to be close enough to the structure or to be progressing rapidly enough to affect structural stability before the next inspection. For the purposes of inspection, the erosion or scour is not closer to the riverside face of the wall than twice the floodwall's underground base width if the wall is of L-wall or T-wall construction; or if the wall is of sheetpile or I-wall construction, the erosion is not closer than twice the wall's visible height.
Additionally, rate of erosion is such that the wall is expected to remain stable until the next inspection.
U Erosion or bank caving observed that is closer to the wall than the limits described above, or is outside these limits but may lead to structural instabilities before the next inspection. Additionally, if the floodwall is of Iwall or sheetpile construction, the foundation is unacceptable if any turf, soil or pavement material got washed away from the landside of the I-wall as the result of a previous overtopping event.

M
A The joint material is in good condition. The exterior joint sealant is intact and cracking / desiccation is minimal. Joint filler material and/or waterstop is not visible at any point.
M The joint material has appreciable deterioration to the point where joint filler material and/or waterstop is visible in some locations. This needs to be repaired or replaced to prevent spalling and cracking during freeze / thaw cycles, and to ensure water tightness of the joint.
U The joint material is severely deteriorated or the concrete adjacent to the monolith joints has spalled and cracked, damaging the waterstop; in either case damage has occurred to the point where it is apparent that the joint is no longer watertight and will not provide the intended level of protection during a flood.
NA There are no monolith joints in the floodwall.
