This Caltrans emergency project involved repairs and preventive measures on Topanga Canyon Boulevard (State Route 27) following a June 29, 2017, wildfire. The incident burned more than 50 acres in steep terrain and prompted the temporary closure of the highway north of Pacific Coast Highway (State Route 1) in Los Angeles County.
Earlier, the same area of State Route 27 was damaged by severe winter storms in January 2017. The storm damage forced the closure of the highway for more than a week due to rock slides and other debris, unstable slopes alongside the roadway and other damage. Working quickly, Caltrans stabilized the slopes, removed large boulders and other material, repaired the roadway, cleaned and fixed the drainage system, replaced guard rails and completed other repairs. After the June wildfire, Caltrans examined the area and determined that additional steps were needed to repair fire damage to the slopes and restrict large debris during future rain events. This work is intended to prevent future closures or disruption of State Route 27 and maintain full access for residents, emergency services and commercial traffic.
In response to the June 2017 wildfire in Topanga Canyon, Caltrans took the following measures to limit the potential threat of more slides during the next rainy season, which could result in additional closures:
Slope along State Route 27 in Topanga that burned in June 2017 wildfire is starting to grow new vegetation. Crews made repairs to burn areas over two weekends in Sept. and Oct. to limit the threat of potential slides during the next rainy season.
One full weekend and one partial weekend closure (3 days total) was needed to complete the work.
The schedule, subject to change, was as follows:
1st Weekend Full Roadway Closure (Daytime) to begin fire damage repair operations:
FULL ROADWAY CLOSURE ON SATURDAY, SEPT. 23, 2017 from 6:00 a.m. to 6:00 p.m., and
FULL ROADWAY CLOSURE ON SUNDAY, SEPT. 24, 2017 from 6:00 a.m. to 6:00 p.m.
2nd Weekend Full Roadway Closure (Night Time) to continue and complete operations:
FULL ROADWAY CLOSURE ON SATURDAY, SEPT. 30, 2017 from 9:00 p.m. to 5:00 a.m., and
FULL ROADWAY CLOSURE ON SUNDAY, OCT. 1, 2017 from 9:00 p.m. to 5:00 a.m.
The Topanga Town Area Will Remain Open.
Bike and pedestrian access is prohibited during the closure.
The repairs were done on a 4-mile section of Topanga Canyon Blvd. (State Route 27) from Pacific Coast Highway to approximately Grand View Drive
