Update as of June 24, 2019

Town Public Works staff and local utilities have been coordinating with Caltrans for the repair of a sinkhole that developed at the El Camino Real/Maple Avenue intersection. However, Caltrans has authority over the roadway, the closure, and the ultimate repair. In response to a Town alert, Caltrans initially responded by placing temporary paving in the hole that had developed at the site. In April 2019, Caltrans began working with local utilities in the area in an attempt to identify the source of the water eroding the pavement under the roadway.
Caltrans took water samples to assist in determining the origin of the water intrusion. Caltrans is exploring the area further to identify the source of the water and Caltrans and associated utilities will be continuing survey work at night when there is less vehicle traffic along the roadway.  The area currently remains covered with steel plates and the affected lanes (both turn lanes and the southbound through lane) remain closed. Caltrans has not advised the Town of when they might be returning to complete the excavation and repair of the sinkhole. Town Public Works staff check in with Caltrans on a regular basis for updates.
