PERRIS, Calif. (AP) - A Southern California recreation area popular among rock climbers and hikers will be closed for three years starting this week for seismic work on a nearby dam.
The Riverside Press-Enterprise reported Sunday (https://bit.ly/1yuGSx0 ) that officials have denied petitions by climbers to keep the 1,500-foot slab known as Big Rock open during the extended shutdown of Bernasconi Day Use Area at Lake Perris.
The area will close to the public Wednesday and remain off-limits to the until work concludes on the dam at the southeast edge of the Riverside County reservoir.
The state plans to inject cement and soil into the dam’s foundation to help it survive a major earthquake.
A 2005 study predicted that the dam would be vulnerable during a quake in the 7.5-magnitude range.
