The Jan. 7 Los Angeles County wildfires debris removal operation was one of our largest, most challenging missions. More than 1,400 USACE personnel deployed from across the nation and from our district to support debris removal operations. /6

But we did not do this alone. The success of this important mission was the result of strong partnerships with FEMA, Cal OES, LA County, local governments and impacted communities. /5

To date, USACE has removed more than 2.6 million tons of debris — the equivalent of more than 218,000 truckloads. /4

We are proud of our efforts, alongside our partners, to rapidly come to the aid of our fellow citizens in their time of need. In just six months, more than 9,500 properties were cleared — making this the fastest, large-scale wildfire debris removal in USACE history. /3

After the devastating Los Angeles wildfires in January 2025, the U.S. Army Corps of Engineers was laser-focused on removing immediate hazards to public health and safety, and supporting economic recovery by removing structural ash, debris and foundations. /2

This week marks one year since the January 2025 Southern California wildfires began. On Jan. 17, the U.S. Army Corps of Engineers began its debris removal mission, which was a critical step in the road to recovery. https://t.co/iF1yZ5D6CP

PUBLICATION NOTIFICATION: Coincidence Processing of Photon-Sensitive Mapping Lidar Data
Link: http://dx.doi.org/10.21079/11681/35599 Report Number: ERDC/GRL TR-20-1 Title: Coincidence Processing of Photon-Sensitive Mapping Lidar Data By Christian Marchant, Ryan Kirkpatrick, and David Ober Approved for Public Release; Distribution is Unlimited February 2020 Abstract: Photon-sensitive mapping lidar systems are able to image at greater collection area rates and ranges than linear-mode systems. However, these systems also experience greater noise levels due to shot noise, image blur, and dark current, which must be filtered out before the imagery can be exploited. Described in this report is a synthetic test data set of imagery from a notional airborne Geiger-mode lidar. Also described is the Bridge Sign algorithm, which uses a least-squares technique for noise filtering. The algorithm’s performance was validated using synthetic test imagery of both a toy scene and of a realistic scene, which were generated using the parameters of a notional airborne Geiger-mode system. Analysis of the results shows the technique effectively removes noise and preserves fine details with good fidelity. 30 pages / 1.568 Mb

PUBLICATION NOTICE: Numerical Sedimentation Investigation Mississippi River Cairo to Pilots Station
Report Number: MRG&P Report No. 30 Title: Numerical Sedimentation Investigation Mississippi River Cairo to Pilots Station By Ronald R. Copeland, Leslie Lombard, Roger A. Gaines Approved for Public Release; Distribution is Unlimited February 2020 Abstract: A HEC-6T numerical model of the entire Lower Mississippi River between the end of Southwest Pass and the confluence of the Ohio River was developed. The model, which included over 1000 river miles, was calibrated to 1991-2002 measured data. The purpose of the numerical sedimentation model was to provide a tool to evaluate the long-term and system –wide effects of specific Mississippi River and Tributaries Project features. Model applications related to the effects of sediment diversions and the effects of dredging in the New Orleans District were demonstrated. The model demonstrated the effects of new constrictive works on the long-term and short-term river morphology. The model was used to test the effects of changes in upstream sediment inflow. The model’s ability to assess the effects of natural geomorphic changes, such as erosion of hard points, was demonstrated. Future application of this model to specific project sites should include the addition of more detailed geometry in the area of interest. 230 pages / 7.8 Mb

Maine Department of Marine Resources seeks Corps permit to build pens to raise Atlantic salmon in Cutler
The Maine Department of Marine Resources is seeking a permit from the U.S. Army Corps of Engineers, New England District to conduct work in waters of the U.S. in conjunction with constructing pens to raise Atlantic salmon in Cutler, Maine. The Maine Department of Marine Resources is proposing to install and maintain up to four, 22.28 meter (m) diameter circular floating fish pens (70m in circumference) within a polygonal shaped area with sides measuring 191m x 88m x 191m x 88m off the south shore of Little River (Cutler Harbor) in Cutler, Maine. The pens will be connected together to form a four pen line and will be secured by 2,200 pound anchors and 4,000 pound granite or concrete blocks.
