The project aims to restore critical transportation infrastructure and improve resilience in the...
The Washington State Department of Transportation (WSDOT) was awarded a $681,520 Project Grant from the U.S. Department of Transportation's Federal Highway Administration under the Highway Planning and Construction (CFDA 20.205) program. The grant funding will support an emergency slope stabilization project on State Route 2 at milepost 143.7 in Washington. This project aims to address critical slope stabilization needs along the state highway system to maintain safe transportation...
This $140,335 Project Grant award from the U.S. Geological Survey (USGS) Cooperative Landslide Hazard Mapping and Assessment Program (CFDA 15.821) supports two key activities in Oregon: Landslide inventory mapping using LiDAR data in the northern portion of Clackamas County. This region has experienced historic landslides and debris flows, and continues to undergo development along a major highway corridor. The detailed mapping will benefit local communities by identifying areas at risk....
The Washington State Department of Transportation (WSDOT) received a $2.186 million Project Grant award from the Federal Highway Administration (FHWA) on March 7, 2023. The funding supports the Highway Planning and Construction program (CFDA 20.205) project to stabilize slopes and reduce the risk of road closures on State Route 109 north of Moclips Highway in Washington state. The Highway Planning and Construction program aims to assist states in providing construction, preservation, and...
The Washington State Department of Transportation (WSDOT) Accounting and Financial Services Division received a $208,999 Project Grant award from the Federal Highway Administration under the Highway Planning and Construction program (CFDA 20.205) to stabilize a slope and reduce the risk of roadway closures along SR 109 - North of Moclips Highway in Washington. This project will help maintain the transportation infrastructure and improve safety in the affected area. WSDOT, as a key state...
The Washington State Department of Transportation (WSDOT) Accounting and Financial Services Division was awarded a $331,651 federal Project Grant on September 7, 2023 under the Department of Transportation Federal Highway Administration's Highway Planning and Construction (CFDA 20.205) program. The grant funding will support a slope stabilization project on State Route 8 from Mile Post 4.88 to 5.00 in Washington, an emergency infrastructure initiative to address slope instability in this area.
The Department of Transportation Federal Highway Administration awarded a $300,557.10 Project Grant on November 16, 2022 under the Highway Planning and Construction federal grant program (CFDA 20.205) to the Washington State Department of Transportation for removal of landslide debris along SR 509 (Marine View Dr). As part of this award, the Washington ST Department of Transportation will provide debris removal services to address a landslide along this state route. A sub-award of $100,000 was...
The Washington State Department of Transportation (WSDOT) was awarded a $100,000 Project Grant from the United States Geological Survey (USGS) Cooperative Landslide Hazard Mapping and Assessment Program (CFDA 15.821) to utilize Interferometric Synthetic Aperture Radar (InSAR) technology to improve existing landslide hazard mapping and characterization within two landslide-prone highway corridors in Washington state.
The project aims to acquire and analyze InSAR data to better understand the landslides affecting State Route 109 and US 101, with the goal of informing WSDOT's efforts to mitigate landslide risks and increase the resilience of these critical transportation facilities. The project will be conducted in two phases - the first involving the InSAR data acquisition and analysis by a consultant, and the second involving geologic reconnaissance by WSDOT engineering geologists to ground truth the identified landslide features. A final technical report will summarize the findings, assess the limitations and merits of InSAR for landslide monitoring, and provide recommendations for incorporating InSAR into a broader statewide landslide monitoring program.
