A geotechnical analysis conducted in late summer indicated long-term deterioration of the soil environment along the slope. Since 2009, the city received 13 work order requests related to mud/rock slides and trees down along Lake Forrest Drive with eight of those work orders occurring in 2013.
The slope stabilization project included installation of a structural catch system and vertical wall. The cost of the project was $750,000. Part of the road was closed for three hours in January 2013 as crews work on an emergency slope maintenance project.
