Request for Proposals for Central Coast Highway 1 Climate Resiliency Study

The Highway 1 corridor near Elkhorn Slough presents significant challenges to the future of transportation in the Monterey Bay region under conditions of climate change and sea level rise that must be addressed. This project will provide a comprehensive assessment of the threats and options available to respond to those threats including the transportation, environmental and economic dimensions. It will develop a risk assessment process grounded in formal analysis and conducted through a stakeholder engagement process. The end result will be a considerably more detailed understanding of the risks and options for adaptation in this critical stretch of Highway 1, as well as an adaptation management strategy to ensure updated scientific information is integrated into the project planning process.

The eight-mile stretch of Highway 1 near Elkhorn Slough is already constrained and will be increasingly impacted by coastal storm flooding and sea level rise. Driven by a need to sustain this critical transportation corridor and to protect the iconic coastal habitat in the face of the unique challenges posed by climate change, a diverse partnership has formed in the Monterey Bay area to join together to find innovative ways to address this complex transportation adaptation problem by exploring creative transportation solutions and the use of natural infrastructure approaches to promote transportation, habitat and economic resilience for the region.

This study will evaluate and identify the transportation needs, including the ultimate corridor concept in the Central Coast Highway 1 corridor near Elkhorn Slough area while protecting and integrating the environmental needs of this unique corridor. There is currently a deficiency in this critical corridor between the adjoining freeway segments to the north and south; existing demand greatly exceeds the limited capacity and numerous intersections and conflict points, causing long delays. Highway and railroad infrastructure are prone to flooding and vulnerable to sea level rise, and are adjacent to valuable wetland habitats of an estuary of noted regional and national significance. Much of these valued habitats are also vulnerable to sea level rise. Here we have an opportunity to increase the resilience of transportation infrastructure and habitat to sea level rise and climate change.

AMBAG has issued this Request for Proposals (RFP) in an amount not to exceed $150,000 for the Central Coast Highway 1 Climate Resiliency Study.
