Resilient IE

Project Overview 

Resilient IE was developed in collaboration with the San Bernardino County Transportation Authority (SBCTA) with funding from Caltrans. Resilient IE works to support regional and local efforts to prepare for and mitigate risks associated with climate adaptation on the region's transportation infrastructure with five primary project components:

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

2)    Subregional vulnerability assessments and adaptation strategies;

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

4)    A regionally-tailored climate resilient transportation infrastructure guidebook; and

5)    A template regional climate adaptation and resiliency element.

Project Deliverables 

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 and Adaptation Strategies

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

In addition to the subregional Vulnerability Assessments, Community Vulnerability Profiles were prepared for all local jurisdictions to better facilitate ease of use of all Resilient IE products at the local levels. Community Profiles can be accessed through the respective subregion link below:

SBCTA Member Community Vulnerability Profiles  

WRCOG Member Community Vulnerability Profiles

As a component of the vulnerability assessment, the project conducted a two-asset pilot analysis testing a method for quantifying the community-wide costs of transportation asset outages under projected future climate-related hazard scenarios. The aim of this effort is to better inform prioritization of transportation infrastructure spending. The pilot analysis report can be accessed through the link below:

Risk-Based Vulnerability Assessment Pilot Findings

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. 

Hazard and Evacuation Maps 

This interactive web map depicts city-level evacuation routes and hazard layers that can be turned on or off to show where particular hazards are a risk across the region. 

Simple, city-level evacuation route maps can be accessed through the links below:

Climate Resilient Guidebook 

The Climate Resilient Transportation Infrastructure Guidebook provides insights on current policy, procedures, local and regional challenges and solutions, and resilient infrastructure strategies. The Guidebook also includes case studies, design examples, and implementation guidance. The Guidebook can be accessed through the link below:

Resilient IE Toolkit 

The Resilient IE Toolkit is a comprehensive document bridging the Vulnerability Assessments, Adaptation Strategies, Hazard and Evacuation Maps, and Resilience Guidebook, including summary findings and highlights of key uses for each and culminating with the complete Template Resilience Element. The Toolkit can be accessed through the link below:

About the Project Funding 

Resilient IE is the recipient of the Caltrans Adaptation Planning Grant funded by 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, were required to prepare a Case Study 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.
