Document Description
The project will restore and stabilize a 10-foot section of the eroding southern bank of Copeland Creek to protect existing nearby utility infrastructure. Erosion occurs between the creek flow line and the top of the bank, a depth of approximately three feet. Other preexisting bank reinforcement/slope stabilization improvements and structures are adjacent to the proposed improvements. The proposed bioengineering solution will incorporate rip-rap slope protection (i.e., one-ton toe boulders keyed three feet into the flow line of the creek and rising three feet above the flow line). Native soils will be restored to match the existing top of bank grade and covered with biodegradable coconut fiber mesh and planted with willow sprigging. Approximately 30 days is required for project implementation during the dry season between August and October. If improvements are not in place by October 15th, temporary settling/silt/catch basins will be created and cleaned out after storms to maintain design capacity.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
• Section 15301 Class 1 (Existing Facilities)
Reasons for Exemption
The project involves repair of a component of an existing structure (slope stabilization/bank reinforcement system) in its present location and with substantially the same purpose and capacity as the structure being replaced. A NOE for an emergency statutory exemption per PRC § 21080(b)(4) was originally filed for this work in July 2019 but the work was not implemented and new plans have since been developed. The current project will result in negligible or no expansion of the capacity of the structure being replaced and improved. Disturbed vegetation will be replaced with appropriate native plant materials. Project effects on biological resources will be temporary and reduced through with avoidance and/or minimal disturbance where possible. None of the exceptions to the use of the categorical exemptions listed in § 15300.2 (a) through (f) of the CEQA Guidelines apply to the project.
