Enforcement No. 2026-15769– Notice to Proceed with Compliance Plan and Schedule (Plan) for Pipe Removal and Site Restoration

The Central Valley Flood Protection Board is enforcing compliance for Enforcement Case No. 2026-15769, requiring the removal of an unauthorized 8-inch diameter PVC pipe installed through the right bank of the Mormon Slough levee near Linden, California, at Levee Mile 3.57. The corrective action involves excavating the levee to a depth of 8 to 12 feet, completely removing the pipe, and restoring the structure to its original conditions using native, moisture-conditioned soil placed in 4- to 6-inch lifts and compacted to verified standards. Compaction testing must be conducted at every 1-foot interval throughout the backfill process to ensure integrity, followed by the installation of a 4-inch aggregate base on the levee crown. No expansion of use or new development is associated with this work, and the project qualifies for categorical exemptions under the California Environmental Quality Act (CEQA) as an enforcement action (Class 21), involving existing facilities (Class 1), and minor alterations to land (Class 4). The responsible party for executing the work is John Dondero, who must adhere to site-specific technical requirements without reliance on external standards like ASTM or AASHTO. The project is administratively managed by Senior Environmental Scientist Angela Nguyen-Tan, and the Notice to Proceed was issued on July 15, 2026, following a posted notice on July 16, 2026. The work is confined entirely to the designated levee location in San Joaquin County, with acceptance occurring on-site under the oversight of the Central Valley Flood Protection Board. There is no solicitation or contract number, no identified pricing or contract value, no formal contract type, and no procurement competition; the action is a regulatory directive implemented under environmental compliance authority. Submission of the Compliance Plan and Schedule must be mailed to the State Clearinghouse in Sacramento, though no formal deadline, page limits, or electronic submission requirements are specified.
