Climate Change Adaptation Study on Transportation Infrastructure


Climate Change Adaptation Study on Transportation Infrastructure

The Del Norte Local Transportation Commission prepared a Climate Change Adaption Study to identify infrastructure including roads and stormwater drains that are predicted to be affected by climate change by the year 2100.  There are approximately 680 centerline miles of roadway in the county under various jurisdictions. The planned short and long term capital and maintenance project needs within the county total $330 million through 2030 for all of the jurisdictions involved. The intent of this study was to ensure that the collective, scarce regional financial resources are directed to the most cost effective projects that are supported by sound data and meet cost benefit thresholds. Many of these valuable assets will be affected by climate change in different ways. In order to protect these assets, a comprehensive understanding of the inventory and the impact of changes in sea level and precipitation must be well understood. Green DOT Transportation Solutions contributed to this study by identifying assets (roads) that are vulnerable to climate change and related stormwater impacts, and developed adaptation strategies.
