Document Description
The City of San Diego Public Utilities Department (PUD) is currently working within the Caltrans Right-to-Way (PROW) of SR-163 on the 45-year old Cabrillo Trunk Sewer Pipeline Rehabilitation Project Phase H-1 using trenchless technology (slip-lining) to repair the pipeline. Recent visual inspection of the sewer main (FSN 28666) revealed that the exiting 15-inch diameter vitrified clay pipe was severely deteriorated and determined to be structurally unsound. Due to the age and condition of the pipe, slip-lining cannot be used for this segment, and because of the historical sensitivity of the area, open-trenching methodology was rejected by Caltrans. Immediate repair work is necessary to prevent a potential and imminent spill and protect the public's health and safety. In the event of a spill, a significant amount of flow could reach public waters at San Diego Bay, causing a significant environmental impact, threatening wildlife habitat, public health, and safety.

Notice of Exemption

Exempt Status
Statutory Exemption
Type, Section or Code
S:15269(b&c),21080(b)(4)
Reasons for Exemption
A visual inspection of the work area was conducted on April 7, 2011 which determined a low potential to impact and/or discover subsurface archaeological resources. A raptor nesting survey was performed at the project site on April 4, 2011, which did not detect any nests in the sycamore trees that were observed. Therefore, the work identified above meets the criteria set forth in CEQA Section 15269(b)(c) of the State CEQA Guidelines which allows for actions necessary to prevent or mitigate an emergency. As noted above, subsequent historical review and after-the-fact permitting will be required for the emergency work within this historically designated area.
