As part of its efforts to deal with the anticipated problems created by the late June-early July wildfire in lower Topanga Canyon that scorched over 70 acres of hillside, Caltrans will be closing Topanga Canyon Boulevard between Pacific Coast Highway on the South and Grand View Drive (Jalan Jalan) on the North on two successive weekends in late September. The closures are necessary to permit Caltrans and its contractors to perform several slope stabilization/debris flow management projects in the immediate vicinity of the burn area before the Winter rains arrive. These projects are designed to reduce the amount of likely debris flows from the hillside areas that burned when the rains arrive and to stabilize one section of the hillside that Caltrans believes may fail and fall onto Topanga Canyon Boulevard at some point in the future, and thereby minimize accidents on and further closures of Topanga Canyon Boulevard in the burn area.
The closures are currently scheduled as follows:
Saturday, September 23, 6:00 a.m. to 6:00 p.m.;
Sunday, September 24, 6:00 a.m. to 6:00 p.m.;
Saturday, September 30, 9:00 p.m. to 6:00 a.m.; and
Sunday, October 1, 9:00 p.m. to 5:00 a.m.
These closures will be hard road closures. Because of safety considerations, no non-Caltrans traffic, whether vehicular, bicycles or pedestrian, will be permitted along Topanga Canyon Boulevard in the affected area between Pacific Coast Highway and Grand View Drive during the closures. Notwithstanding the closures, businesses and public facilities in Topanga are expected to remain open during the closures and look forward to your continued patronage.
Caltrans recognizes that these closures inconvenience many people and businesses, both in Topanga and for the cross-canyon commuters who utilize Topanga Canyon Boulevard. Scheduling the closures for the weekends is one effort on the part of Caltrans to minimize the inconvenience. Scheduling the first closure for daylight hours and the second closure for nighttime hours is an accommodation that will hopefully further reduce the inconvenience to everyone while still permitting Caltrans and its contractors to safely perform their work.
As always, these closures may be rescheduled by Caltrans as the scheduled dates get closer as a result of adverse weather or other factors. The duration of the individual closures are also subject to change. It is also possible that additional closures will be necessary to complete the scheduled projects, although those closures may only require the closure of a single lane, rather than a full closure of Topanga Canyon Boulevard. Any such additional closures related to these projects will likely be nighttime closures.
