Notice of Exemption
Exempt Status
Declared Emergency
Type, Section or Code
Sec. 21080(b)(3); 15269(a)
Reasons for Exemption
This project repairs the Gordon Slough north levee to its original status prior to the 2019 storms. The Gordon Slough bank below the Sailsbury Spillway was originally stabilized in 2003 to protect against the threat of flooding the Nature Preserve and washing out the bridge into the property, the only vehicle access to the site. Storm waters in 2019 eroded the bank beyond the original stabilization work; the slough banks have eroded further and now threaten a service road and telephone lines. In 2019, at least three threes were lost as the bank eroded out from under them.
