Summary: As a result of the winter rain storms of January 1995, two Santiago Aqueduct Commission (SAC) water supply pipelines were threatened by scour. The two pipes pass under the Borrego Canyon Wash. The Borrego Canyon Wash Interim Erosion Control Facilities Project (Project) was initiated in January 1995, to replace the eroded soil cover layer over the pipes and to restore the protection to the pipelines originally offered by the banks. A second group of storms hit in February 1995, causing an immediate threat to the pipelines where the banks were originally damaged during the January storms. The SAC took emergency steps to protect the pipelines by placing riprap along the banks. DSR 26246 (Category B) was approved to cover the cost associated with the placement of riprap to abate an immediate threat to the pipelines. The costs of the Project were covered under DSR 91666. At the time of the inspection, the FEMA inspector and the State representative agreed that the work was not eligible, stating that the site is a natural feature and there is no threat to lives, public health or safety. The Regional Director upheld this determination in the first appeal. In the second appeal, the subgrantee noted that the scope of work is designed to restore the flowline of the Wash, thereby protecting the facility.
Is the eroded channel bank a facility?
Can the Project be considered an emergency protective measure?
No. The eroded slope is not improved and maintained as is required for a natural feature to be a facility.
No. The project cannot be considered an emergency protective measure since emergency steps to protect the pipelines were covered under DSR 26246. The project was initiated to mitigate future damages.
A natural feature must be improved and maintained in order to be considered an eligible facility. (44 CFR 206.201(c))
In order to be eligible, emergency protective measures must eliminate or lessen immediate threats to life, public health or safety. (44 CFR 206.226(a)(3))
