Document Description
Approval and implementation of a Plan for Enforcement Case No. 2026-15769 to remedy installation of an unauthorized 8-inch diameter PVC pipe through the right bank of the Mormon Slough project levee. The corrective work consists of excavating the levee 8 to 12 feet deep, fully removing the pipe, then restoring the levee to pre-project conditions using the native, moisture-conditioned soil for compacted backfill in
4 to 6-inch lifts. Lastly, the levee crown will be restored with 4 inches of aggregate base. Compaction tests are planned to be taken at every 1 foot interval. No expansion of use or new development is proposed.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
(California Code of Regulations, Title 14, Sections 15321, 15301, and 15304.
Reasons for Exemption
The project is exempt from CEQA under the Class 21, Enforcement Actions by Regulatory Agencies categorical exemption (California Code of Regulations, Title 14, Section 15321), because the activity consists of actions taken by a regulatory agency to enforce applicable laws, regulations, and/or permit requirements. Specifically, the
project implements a compliance action requiring the removal of an unauthorized pipe placed within a project levee and restoration of the site to pre-disturbance conditions. Additionally, the project is also exempt from CEQA under Class 1, Existing Facilities categorical exemption (California Code of Regulations, Title 14, Section 15301),
because the activity consists of the demolition and removal of accessory structures with negligible or no expansion of use. The project is also exempt from CEQA under the Class 4, Minor Alterations to Land categorical exemption (California Code of Regulations, Title 14, Section 15304), because the activity consists of minor
grading and restoration work involving excavating the levee and removing previously placed soil and restoring the levee to pre-project conditions. Restoring the existing site does not involve the removal of healthy, mature, scenic trees. The project is limited in scope, occurs within a previously disturbed area, and will not result in a reasonable possibility of a significant environmental effect. Further, none of the exceptions to the exemption in California Code of Regulations, Title 14, Section 15300.2 apply.
