Document Description
The project would remove an abandoned 24-inch steel pipe penetration (Utility Crossing Inventory Program Desk Study ID, or UCIP DS ID: 20416) within the Sacramento River West Side Levee prism, along Wilson Bend Road in Colusa County. The project would require complete excavation of the levee section at the project site, followed by reconstruction of the levee after pipe removal. Project activities would involve closure of a portion of Wilson Bend Road in the project vicinity during construction, traffic detour routing, disturbance to a depth of approximately 15 feet below the levee crown, temporary stockpiling of excavated material in a staging area on the landside of the levee adjacent to the excavation area, disturbance to approximately 0.58 acres (including the construction staging and excavation areas), reconstruction of the levee section, asphalt road repair, guardrail replacement, and roadway re-striping. Removal of the abandoned pipe would limit the potential risk of levee damage/failure resulting from potential water penetration at the pipe location during a high-water event. Funding for this Deferred Maintenance Project (DMP) Rehabilitation is provided by the Department of Water Resources under the Budget Act of 2018 (Stats. 2018, Ch. 29, Item 3860-001-0001). DMP Rehabilitation is intended to address specific deferred maintenance issues for the State Plan of Flood Control (SPFC) that are recognized as high risks to levee integrity, one of which includes aging pipe penetrations.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Class 1, Existing Facilities (Section 15301)
Reasons for Exemption
No sensitive habitat or special status species were identified in the project site. Furthermore, sensitive habitat, including riparian habitat and elderberry shrubs, adjacent to the project site would be avoided, and adherence to appropriate construction work windows and other environmental protection measures incorporated into the project design would ensure there would be no direct, indirect, or cumulative impacts to special-status plant and wildlife species that have the potential to occur in the project area. The project would also not affect the eligibility of the levee for listing in the California Register of Historical Resources, no other cultural resources were identified in the project area, and environmental protection measures incorporated into the project design would ensure there are no direct, indirect, or cumulative impacts to previously undiscovered cultural resources, human remains, or paleontological resources that may occur in the project site. Finally, there are no scenic highways or hazardous waste sites in the project area that could be affected by the project. Therefore, the project would not have the potential to result in significant impacts to the environment.
