Climate Change
Adaptation Workshop
Our greatest risks and
how we identified them in
the project:
Highways and Transport
The Workshop
Aims:
- To increase understanding of Climate Change risks, the risk
management process and the adaptation actions required for
Highways & Transportation
- To have worked through the process to reach a detailed risk
assessment and management plan for the most significant risks.
LCLIP and Case Studies
CWAC Risk Assessment Methodology
Workshop 1 – Identifying & Quantifying the Risks
Workshop 2 – Assessing Existing Risk Management Plans
Workshop 3 – Identifying Risk Management Options
Scoring
•
•
Two scores
Current - where you are
now (with existing
controls)
Target
- where you will
be (with proposed
actions)
Risk Score = Likelihood x
Impact
Likelihood of occurrence
happening
Impact if it does occur
•
Scores are 1(low) to 4 (high)
•
It is the relative scores that
are important not the
absolute

Prioritising Risks
Housekeeping
Primary
These risks have a high likelihood
of happening do lower impact; they
require routine management
These risks have high impact and
likelihood; these will require
primary attention
Contingency
Non threatening
LOW
These risks have high impact but lower
likelihood; they are
catastrophic events
Impact
HIGH
Identifying the Risks:
-Deterioration of Highways Assets:
roads bridges etc.
-Risk from maintenance: lack of and
increasing need, inspections
-Impact from weather events,
especially interacting events
-Increased accidents etc
-Related consequences: Ground
shrinkage, subsidence: landslides etc
caused by drought and lower water
tables
More Risks: Knowledge
• Knowledge of vulnerabilities,
internally and externally
• Incomplete assets
understanding
• Flood mapping data
• Surface Water Management
Plans
• Information held by United
Utilities, Env Agency,
Emergency Services etc.
Long Term Risks
• Local Development Plan: future
development: industry, housing,
critical infrastructure etc.
• Local Transport Plan 3
• Existing Areas at risk: major
sites Sealand Road Industrial/
Retail
• Over 1,700 businesses in
Cheshire & Warrington are at
risk of 1:100 year flooding
Next Steps
• Report to Director
– Action plan
– Ownership/ responsibilities
• Member engagement
– Risk Management session
– Presentation to groups
– Budget implications
