Document Description
The proposed project involves bridge reinforcement and stabilizing of a stream channel at the western part of the Marin Country Club site. Storms in winter of 2016-2017 and 2018-2019 resulted in significant runoff events that downcut and incised the creek channel, exposing shallow foundations around the bridge and exposing the sanitary sewer line leaving both the sewer line and bridge vulnerable to failure in future runoff events. Failure of the sanitary sewer line would result in spilling of untreated wastewater into the waterway and interruption of essential sewer service to properties served by the sewer line and represents a risk to public health, safety and welfare. Failure of the bridge also represents a risk to users of the golf course and a risk to public health, safety and welfare. Both of these potential hazards would be addressed by the proposed project, which would stabilize the stream channel, reinforce the bridge; and protect the sanitary sewer line by creating a naturalized step pool configuration and using vegetative soil lifts to stabilize the stream banks. Work would be completed within 15 work days and no work would occur during precipitation events.

Notice of Exemption

Exempt Status
Emergency Project
Type, Section or Code
Sec. 21080(b)(4); 15269(b)(c)
Reasons for Exemption
The project meets the conditions for an emergency project exemption described in Section 15269(b) and 15269(c) of the State CEQA Guidelines: (b) Emergency repairs to publicly or privately owned service facilities necessary to maintain service essential to the public health, safety or welfare. Emergency repairs include those that require a reasonable amount of planning to address an anticipated emergency. (c) Specific actions necessary to prevent or mitigate an emergency. This does not include long-term projects undertaken for the purpose of preventing or mitigating a situation that has a low probability of occurrence in the short-term, but this exclusion does not apply (i) if the anticipated period of time to conduct an environmental review of such a long-term project would create a risk to public health, safety or welfare, or (ii) if activities (such as fire or catastrophic risk mitigation or modifications to improve facility integrity) are proposed for existing facilities in response to an emergency at a similar existing facility. The project involves emergency repairs to a privately owned facility, necessary to correct exposure of the sanitary sewer line and bridge. These emergency repairs would be completed within 15 work days and are necessary to prevent failure of the sanitary sewer line and bridge, and to prevent any potential risks to public health, safety, and welfare.
