5 Challenges
6 • State/federal regulations for
flood protection are
becoming stricter
• Weather extremes are
unpredictable
• Every major storm event
stresses levee system
• Levees are the only/last
defense against flooding
Problems to Avoid
7 • Physical damages from flooding
• Calaveras/San Joaquin Rivers
• Creeks, Sloughs, Channels
• Financial impacts from failure to meet changing state/federal regulations
• FEMA remapping of Special Flood Hazard Areas
• Loss of federal funding for emergency repairs to levees Cost of Flood Damage

Loss of eligibility for federally-

Cost of repairing levees is 100%
community responsibility
Repairs typically $1M or more
How do we
defend lives,
property?
1) Improve levee
maintenance services
2) Improve levees beyond
100-year level of flood
protection
Improve Levee Maintenance (O&M Services)
12 Adequately fund maintenance for existing and improved levees o Removal of debris that obstructs storm water and flood flows, damages levees o Vegetation removal and control
o Rodent removal and control
o Levee patrol during high water warning and flood stages o Resurfacing of levee maintenance and patrol roads
o Construction of erosion repair and protection
o Repair of levee embankments
o Inspection and repair of gates
o State and federal inspections and evaluations
o State and federal permit applications and compliance

22 Assessment Methodology
Every property’s assessment differs based on property characteristics:
Land use category
Parcel size (acres)
Location of Property – determines:
Benefit of Levee O&M Services (Y/N)
Which breach scenario impacts the parcel (for Levee O&M Services) Benefit of Levee Capital Services (Y/N)
In Smith Canal Area Assessment District (Y/N, only for Levee Capital Services) Depth of flooding for O&M and Capital (separately)
23 Example Assessments – Single Family Home
24 Property Characteristics:
• Land Use: Single-Family
Residential
• Parcel Sizes for Examples –
0.1 Acres, 0.25 Acres, 0.5 Acres
• Average flood depths by category
Categories
1) O&M Only (one breach)
2) O&M (three breaches) and Non‐LSJRP
Accredited Levees
3) O&M (three breaches) and LSJRP Capital
Examples – Single Family Home
