STUDIES & EVALUATIONS

Activities related to evaluating all SPFC facilities to identify any deficiencies, and prioritizing

(emergency, critical, serious, monitor) them for repair, rehabilitation, or replacement. These

evaluations include:

• Levee stability

• Levee penetrations, such as pipes and culverts


15

• Channel capacity

• Structure functionality

• Levee Tree Assessment

• Encroachments

• O&M right-of-way

Channel Evaluation

Cache Creek Channel Evaluation

• Preliminary evaluation is completed. A summary report is being prepared.

Levee Evaluation

Pipe/Culvert Evaluation

• Phase 1 video inspections: o 169 of 253 pipes passing through SMA levees have been video inspected by FMO.

Levee Tree Assessment

• No levee tree assessments are conducted during the winter. Assessments will restart in Spring 2020.

DEFERRED MAINTENANCE

Maintenance that has not been completed to keep the facilities in an acceptable and

operable condition will result in deferred maintenance. If the work is not completed as part

of O&M activities, it will lead to a larger maintenance issue and cost significantly more.

Pipe Rehabilitation

• 77 pipes have been rehabilitated using the Cured In Place Pipe method in SMAs, including: o Rehabilitation of 42 pipes is completed in Willow Slough, Putah Creek, and West

Levee Yolo Bypass. New flood control gates have been installed on 38 of these pipes.
