Deukmejian Wilderness Park Debris and Sediment Haul

Glendale is receiving compensation from other jurisdictions for allowing them to haul sediment and debris up to the placement site next to Deukmejian Wilderness Park.  Glendale is also responsible for prior damage done to an underground gas line by such trucks.

✔ In preparation for winter storms, Los Angeles County Public Works is performing maintenance at flood and debris control facilities affected by the September 2017 La Tuna Fire to provide increased protection to local communities. The facilities are located within burned canyon areas that have the potential to release large amounts of sediment and debris when it rains. Removal of this sediment and debris is necessary to maximize storage capacity prior to the storm season, and following each significant debris-producing storm. LA County trucks are following  haul routes and taking sediment to the LA County Dunsmuir Sediment Placement Site (SPS) near Deukmejian Wilderness Park.  Dunsmuir SPS is an engineered regional site that has been owned and operated by the County to deposit sediment since the 1950s.

In speaking to LA County Public Works, they have indicated that the expected finish date is March 2018, barring any unforeseen circumstances such as a storm.


Moving the sediment out of a debris basin requires excavation equipment and numerous dump trucks. Due to a debris basin's function to protect neighborhoods, most often residential ones, these dump trucks have to utilize the local streets to transport the sediment to a Public Works' sediment placement sites or some other authorized disposal sites. This presents certain regrettable but unavoidable consequences such as dust, noise, and increased traffic and travel times along the streets compromising the haul route. However, if the basins were not cleaned out, even worse consequences of debris flows and localized flooding would cause significant damage and endanger local residents. Understanding these possibilities hopefully helps residents understand and better endure short-term inconveniences along a haul route. To learn more about the process, click here.
