Resilient IE

Resilient IE is a collaborative effort between WRCOG and the San Bernardino County Transportation Authority (SBCTA), funded by Caltrans, that is working to support regional and local efforts to prepare for and mitigate risks associated with climate adaptation and transportation infrastructure.  Caltrans awarded a total of $683k to develop six primary project components:

1)     A newly established regional climate collaborative, the “Inland Southern California Climate Collaborative (ISC3);

2)     A revision to WRCOG’s community vulnerability assessment (VA) and establishment of a VA for San Bernardino County;

3)     City-level, climate-related transportation hazards and evacuation maps;

4)     A climate resilient transportation infrastructure guidebook;

5)     A regional climate adaptation and resiliency template general plan element; and

6)     A pilot project assessing the true, community cost of a downed or damaged transportation asset.

Project Deliverables


The Resilient IE Toolkit is a comprehensive document linking all primary written project components (2-5 above), including summary findings and highlights of key uses for each, along with links to the full documents (also linked below) and culminating with the Template Resilience Element.

Inland Southern California Climate Collaborative (ISC3)

Launched in early 2020, ISC3 is a diverse, cross-sectoral network of agencies, organizations, companies, and institutions working together to advance equitable solutions to create a resilient and thriving Inland Southern California. ISC3 covers all of Riverside, San Bernardino, and Imperial Counties, and is recruiting members now, click here to learn more.

Vulnerability Assessments

The revised WRCOG VA and newly prepared San Bernardino County VA are complete and now available for download:

Hazard and Evacuation Maps

The city-level hazard and evacuation routes depicted in this interactive web map includes routes and hazard layers.

Simple, city-level evacuation route maps are available below:

Climate Resilient Guidebook

The Climate Resilient Transportation Infrastructure Guidebook  provides insights on current policy, local and regional challenges and solutions, resilient infrastructure strategies, procedures, case studies, design examples, and implementing guidance. 

Template Resilience Element – Coming Soon

The template element is currently in its final stages of development and will be released in February 2020. In late fall 2019, the project team held a series of webinars and in-person meetings to gather input on the regional climate adaptation and resiliency template general plan element. The presentation slides from those meetings are available below:

 Risk-Based Vulnerability Assessment Pilot – Coming Soon

As a component of the vulnerability assessment, the project conducted a two-asset pilot analysis seeking a method for quantifying the community-wide costs of transportation asset outages under projected future climate-related hazard scenarios to enable better informed prioritization of transportation infrastructure spending. The pilot analysis report will be released in February 2020. WRCOG and SBCTA have secured additional funding from Caltrans for a follow up study that will expand on the work of this pilot. That study will commence in early 2020 and conclude in February 2022. 

About the Project Funding

Resilient IE is the recipient of the Caltrans administered Adaptation Planning Grant from Senate Bill 1, the Road Repair and Accountability Act of 2017. As a component of the Adaptation Planning Grant program, Resilient IE, and other grant awardees, must prepare two Case Studies for the Integrated Climate Adaptation and Resilience Program (ICARP). ICARP is designed to support cohesive and coordinated responses to climate-related issues across all levels of government. The Case Studies are intended to serve as a resource for others looking to understand how to implement similar programs and/or achieve similar project goals. To access the complete archive of Case Studies, visit The Resilient IE Case Study prepared at the onset of the project is available here. A final Resilient IE Case Study will be prepared at the conclusion of the project.
