January 2017 storm events overflowed the capacity of a concrete lined storm drain and caused the embankment to down cut approximately 30 feet, forming a gully. The down cut occurred within the road embankment along Condor Avenue and a residential single family home. After the embankment eroded, a winterization project occurred to prevent further erosion. The winterization project included the creation of a temporary swale to carry impending storm runoff; installation of a 36-inch diameter plastic culvert; installation of rock slope protection at the base of the swale; and installation of plastic sheeting over the eroded slopes of the gully.
The project covered under the Streambed Alteration Agreement is limited to the removal of the winterization project and the installation of an underground culvert at the gully. The project will not rebuild the embankment to pre-storm conditions.
