DISTRICT DIRECTOR EMERGENCY ORDER EL MORRO 0U1604

This is a District Director’s Emergency Project on State Route 1 (SR-1) adjacent to El Morro in Laguna Beach, Orange County. Project work includes installation of a soldier pile retaining wall system at post-mile 12.07, consisting of six (6) soldier beam piles installed in 30-inch diameter holes, drilled 6 feet apart. The wall length is 30 feet and the height will be 15 feet plus the embedment depth of 30 feet below the dirt grade. The wooden laggings shall be installed along the entire length of the wall. The laggings shall extend approximately 3 feet into the native intact soils down to 15 feet and flanks of the gully. Outside the gully, the lagging shall be installed to a depth of 2 feet below the grade. The soldier pile wall shall be constructed at a 6-foot and 8-inch offset from the edge of pavement. There will be removal of approximately 206 feet of Metal Beam Guard Rail (MBGR) and replacement of it with required Midwest Guardrail System (MGS) with a transition section to join both ends of the existing MBGR. The MGS will be at the same location as the current guardrail. The length of the MGS is 206 ft, there are about 23 posts. Each post will be about 40” under the ground, post size is 6” by 8”. The V-ditch has been eroded/washed away, and it will be restored once the retaining wall is constructed and the hole is backfilled. For the ditch, lined rip rap as opposed to Hot Mix Asphalt will be used. The purpose of the project is to repair the erosion gully that is rapidly eroding away. The need is due to erosion gully area being compromised, enlarged and undermining the asphalt shoulder and roadway embankment which serves a high volume of vehicle and bicycle traffic to the South County coastal regions. This project is State/federal funded. All work will occur in Caltrans ROW. No new ROW is required.
