was a mudslide on the back side of the property. This property is adjacent to Wilkie Creek which is associated with the mudslide. Reportedly, the property’s previous owner had been discussing this mudslide with City staff circa 2021.
With the rains in the winter, the resident noticed that the mudslide worsened and unfortunately collapsed a portion of their fence. City staff and the City’s consultant (Questa) immediately investigated and confirmed the mudslide.
The responsibility to mitigate the mudslide is the responsibility of the adjoining landowners per Richmond Municipal Code Section 12.08.030. This section of the RMC states it is the responsibility of the property owner who borders the watercourse carrying storm water to clean and maintain it on a regular basis. This includes removal of overgrown vegetation and keeping mud and silt from accumulating in the creek. The Public Works Department sent letters to property owners on Salvino Court and De Anza Drive who are bordering Wilkie Creek on February 17, 2023, to remind them about this responsibility. Unfortunately, the mudslide continued to worsen and threatened the structural integrity of Santa Rita Road near the aforementioned address.
On or around March 10, 2023, the City’s consultant recommended that the City take immediate action to mitigate the effects of the mudslide. City staff contacted contractors for remediation work at this site, and Bay Hawk, Inc. was immediately available to perform work to stabilize the earth slopes adjacent to Santa Rita Road.
City staff is recommending City Council approve an after-the-fact emergency slope stabilization contract with Bay Hawk, Inc. for $60,000.
