Reslient IE
»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.

Reslient IE
»Resilient IE is the recipient of the Caltrans
Adaptation Planning Grant funded by Senate
Bill 1, the Road Repair and Accountability Act
of 2017
Grand Terrace Planning CommissionResilient IE
5 primary project components
»A newly established regional climate collaborative,
the Inland Southern California Climate Collaborative
(ISC3)
»Subregional vulnerability assessments and
adaptation strategies
»City-level, climate-related transportation hazards and
evacuation maps
»A regionally-tailored climate resilient transportation
infrastructure guidebook
»A template regional climate adaptation and resiliency
element
Grand Terrace Planning CommissionResilient IE
Regional Climate Hazards
»Numerous climate hazards in the region
•Everyone may be affected, but some more severely
»Hazards have worsened over past decade
»Associated risks:
•Increased threat to public health and safety
•Greater likelihood of property and infrastructure
damage
•Harm to regional economic drivers
•Higher costs to rebuild
•Loss of regional ecosystems

Why Resilient IE Toolkit?
»Goal: Make it easier for communities to increase
resilience of transportation infrastructure to
climate-related hazards
»Supports integration of climate adaptation planning into local
processes
»Allows for easy and more effective implementation
»Helps communities comply with State regulations
•SB 379 –Safety Element Vulnerability
•AB 747 –Evacuation Routes
•SB 1000 –Environmental Justice

»Guidance for use
»Legislative context
Grand Terrace Planning CommissionResilient IE
Vulnerability Assessment
»Identifies climate-related hazards in
the area and how they are projected
to change.
»Assesses how populations and assets
may be harmed by these hazards
»Measures level of vulnerability
•How severe are the effects?
•How easily can the population or asset
recover?
»Jurisdiction-specific vulnerabilities
Grand Terrace Planning CommissionResilient IE
1. Evacuation Mapping
»City-level evacuation routes for entire
subregion
»Hazard overlays with evacuation routes
•Shows key routes and infrastructure to
prioritize transportation resilience measures.

1. Hazards
Wildfire
Drought
Flooding
Air quality, human health and
ecological hazards
Severe weather
Extreme wind
Mudslides and landslides
Grand Terrace Planning CommissionResilient IE
2. Flooding
»Extreme precipitation events may become
more frequent and intense
»Wet seasons (those with a 4% chance of
occurring in any given year
»Precipitation increases are projected
»Warmer temperatures are projected to drive
earlier and more rapid snow melt
Grand Terrace Planning CommissionResilient IE
3. Severe Weather
»Atmospheric rivers could be approximately
25% longer and more frequent
»Increase in winter precipitation with warmer
temperatures rive earlier and more rapid
snow melt

4. Adaptation Strategies
»Recommendations for improving resilience across sectors
»Address 9 priority areas identified in VA
1.Planning and Emergency Response Frameworks
2.Disadvantaged Communities
3.Public Health
4.Transportation Infrastructure and Operations
5.Resilient Development
6.Water and Energy Resources and Reliability
7.Agriculture
8.Biological Resources
9.Plan Maintenance
»Foundation for communities to develop local policies
Grand Terrace Planning CommissionResilient IE
5. Resilient Transportation Guidebook
»Improve transportation infrastructure resilience
»Addresses challenges identified in VA and
evacuation mapping
»Includes:
•Resilience strategies
•Funding opportunities
•Potential impediments and obstacles
•Templates for costs
•Maintenance regimes
•Case studies and design examples

6. Resilience Template
»Helps communities develop and implement local adaptation efforts
»Builds on other components of the toolkit
»4 Primary Components
1.Model strategies: examples of regional adaptation strategies customized for
local use
2.Strategy prioritization methodology
3.Strategy document applicability
4.Implementation guidance

Climate Collaborative
»Regional forum supporting adaptation
and resilience planning across sectors
»Launched in 2020
»Administered by Climate Resolve
»Recruiting members now
Grand Terrace Planning CommissionResilient IE
Risk-Based Vulnerability Pilot
»Alternate approach for prioritizing
funding across at-risk infrastructure
»Utilizes VA and existing data (e.g.
transportation demand models)
»Analysis of two assets:
•I-10 near ONT
•I-15 Cajon Pass
»Precursor to full analysis to kick-off
soon with additional Caltrans funding
