The purpose of the South Coast Slide Study project is to develop a plan for transportation resiliency along U.S. 101, between Port Orford and Brookings.
Landslides and road failures along this segment have been an ongoing problem for decades. These events result in full or partial closures of travel lanes and require days or even weeks of maintenance work to be able to fully reopen to passenger car and heavy vehicle travel.
As a result, these landslide and road movement incidents have a significant cost to Oregon Department of Transportation (ODOT), disrupt the local and regional economies, strain emergency services, and reduce the mobility of communities to reach critical services.
This study will identify technically feasible and cost-effective projects and management strategies that will:
- Increase landslide recurrence intervals.
- Reduce recovery times after events.
- Improve safety and operations along U.S. 101, Carpenterville Road, and other viable detour routes.
- Identify effective short-term solutions to facilitate passenger, emergency, and freight vehicle travel through the area after an incident.
- Reduce ODOT operations and maintenance costs.
- Reduce socio-economic costs to impacted communities.
Lastly, this study will fill the need for a single easily accessible location to document data related to the study landslides. Data, studies, and previously reviewed alternatives are currently stored in many locations and in a mixture of formats. This project will consolidate and summarize known data sources and documents to better serve the region and respond to public inquiries.
