February 20, 2017 at 4:08 PM Today, the soils engineer has placed monitoring devices in several key locations so that county staff can gauge the movement.  The slide area will continue to be monitored by emergency responders, County staff and the soils engineer.  Unfortunately, there isn’t much else that can be done at this time due to the steep terrain.  Some minor sloughing has also been reported just east of the primary slide area.

February 20, 2017 at 10:59 AM Update:  The site of the landslide in Cascade Shores is along Pasquale Road at Mountain View Drive.  Mountain View Drive and Pasquale Road surrounding the potential landslide area are closed for safety.  Any non-emergency personnel should stay out of the area.

A soils engineer was consulted this morning and confirmed that the mandatory evacuation of a few homes in the area is prudent especially with more rain predicted throughout the week.  If the slide should continue to move, it does not appear that the Cascade Shores Wastewater Treatment Plant will be impacted.  The potential landslide site cannot impact Scott’s Flat Lake as it is on the other side of the hill from the lake.

February 20, 2017 – Thanks to Joshua Pack from Nevada County Public Works for the morning update on the landslide in Cascade Shores. The slide was first reported around 4 pm as listed on our Happening Now log.

“Last night Public Works staff was called out to a slide developing in Cascade Shores (behind Pasquale and Mountain View).  Several homes could be impacted including Mountain View Road and potentially the Cascade Shores Wastewater Treatment Plant.  Mountain View is closed at Pasquale, and homes in this area have been evacuated. Later today soils engineers will be onsite to assess the slide to determine the severity of the situation. This new slide does not appear to be related to the slide that damaged the plant back in the 2000s,” Pack stated in an email.

According to county staff onsite last night, NID was also at the landslide location. There was no discussion of any potential impacts to Scotts Flat Dam. Given the location of the slide, it is unlikely Scotts Flat could be affected.

A hard closure of Mountain View Drive is in place.
