Document Description
Repair of failed roadway, specifically reconstructing the road with a cast-in-drilled-hole (CIDH) concrete retaining wall extending approximately 370 feet, with wall heights between 4 and 10 feet. Relatively closely spaced piles will transfer lateral soil loads to deeper and stronger materials. Filling and repaving the roadway will be required to
restore the asphalt surface and pre-slide drainage patterns. The project shall incorporate best management practices and erosion control measures, as well as environmental commitments to protect environmental resources, including any
potential special-status species or cultural resources that may occur in the project area. One lane of travel will be maintained at all times during construction. Post project the area below the retaining wall will be hydroseeded with a native grass seed
mixture and any trees lost due to the slide will be replaced

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
15301 Class 1-Existing Facilities,15302 Class 2-Replacement or Reconstruction, and 15304 Class 4-Minor Alterations
Reasons for Exemption
The proposed project would be considered Categorically Exempt from CEQA pursuant to Section 15301 Class 1-Existing Facilities, which includes the operation and repair of existing public or private structures or facilities involving negligible or no expansion of existing of former use. The proposed improvements would also be considered Categorically Exempt pursuant to Section 15302 - Replacement or Reconstruction, which consists of replacement or reconstruction of existing structures and facilities where the new structure will be located on the same site as the structure
replaced and will have substantially the same purpose and capacity as the structure replaced. The slide repair would also be considered Categorically Exempt pursuant to Section 15304- Minor Alterations to Land, which consists of minor public alterations to the condition of land, water and/or vegetation which do not involve the removal of healthy, mature, scenic trees. A key consideration in the appropriateness of using these Categorical Exemptions is whether the project would be located on the same site, have substantially the same purpose and involves negligible or no expansion of an existing use. In terms of negligible expansion, the proposed project will generally take place within the existing facility's footprint and does not include significant
expansions beyond existing conditions - areas impacted by the slide will be restored with hydroseed and replacement trees but not expand the road; just repair and restore the existing road access. The proposed project would restore the travel lane width and legal load capacity of the existing facility to improve public safety and would bring the facility into compliance with current Road and Street Standards. Therefore, it has been determined that the proposed project qualifies for a Class 1, Class 2 and
Class 4 Categorical Exemption, and has no reasonable possibility of having a significant effect on the environment. The site is not on any of the lists of hazardous waste sites enumerated under Government Code Section 65962.5.
