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 Empire Regional Climate Collaborative” (IERCC);
  2. A revision to WRCOG’s community vulnerability assessment (VA) and establishment of a VA for San Bernardino County;
  3. A pilot project assessing the true, community cost of a downed or damaged transportation asset;
  4. City-level, climate-related transportation hazards and evacuation maps;
  5. A climate resilient transportation infrastructure guidebook; and
  6. A regional climate adaptation and resiliency template general plan element.

Project updates:

An exploratory meeting for a potential IERCC was held on August 6, 2019, and convened over 70 stakeholders from the public, nonprofit, and private sectors. The collaborative concept was well received by attendees and, as a result, the project team is now preparing to launch a collaborative in early 2020.

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

The city-level hazard and evacuation routes are complete for all communities across western Riverside and San Bernardino Counties. This interactive web map includes routes and hazard layers. Simple, city-level evacuation route maps are available below:

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

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.

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.
