Incorporating Extreme Weather
Risks in Asset Management
Planning

What is a Transportation Asset
Mgmt Plan (TAMP)?
• A tool used to manage an organization's
infrastructure and other assets with the objective of
delivering an agreed upon standard of service
• Establishes a consistent and transparent statewide
approach to planning, programming, and
managing physical assets
2
Benefits of a TAMP?
• Lays out the process of how to best manage the highway
pavements, bridges & other physical assets for the long
term
• Resource allocation decisions are based on data and
analysis
– Consideration of engineering, life-cycle cost, and risk analysis
with investment strategies
• Improved coordination between maintenance,
preservations, and capital programs
3
Key MAP-21 Components of TAMP
• Asset Inventory/Conditions
• Objectives/Measures
• Performance Gap
Assessment
• Lifecycle Cost
• Risk Analysis
• Financial Plan
• Investment Strategies

FHWA Asset Management Plan
Pilot Project
• Support three state DOTs
developing their first TAMP
Minnesota
– Develop TAMP Work Plan
• Working with FHWA & MnDOT
consultants
Louisiana
New York

MnDOT’s TAMP Progress
 Asset inventory & condition collected for all four asset
categories
 Life-cycle cost analysis complete
 Risk assessment complete
– Workshop on November 15 to discuss mitigation strategies,
costs, and risk impact
• Financial investment strategies & performance targets
– Workshop on November 15 will also include discussion of
financial plan elements
7
Life-Cycle Cost
• Describe lifecycle costs & why they are important
• Illustrate a typical deterioration model
• Describe strategies for managing assets over their whole
life
• Contrast lifecycle costs for different strategies
• Document the lifecycle cost of adding a new lane

Pavement LCCA Results

Risk Assessment
• Working Groups Identified Risks
– Impacts to Asset, Users, MnDOT
– Consequence & Likelihood
– Mitigation Strategies & Gaps
• Workshop (9/20) Focus on “Undermanaged”
Risks
• Comparative Prioritization Exercise
10
Risk Results
• Few Very High Risk areas
• Top (Prioritized) Undermanaged Risks
– Inability to appropriately manage culverts
– Not meeting public expectations for local/corridor level
pavement quality/condition
– Tunnel and culvert failure or collapse
– Premature deterioration of a bridge

MnDOT’s Flash Flood Vulnerability
and Adaptation Assessment Pilot
Project in NE & SE Minnesota
12
Project Background
• Minnesota GO Vision &
Statewide Multimodal
Transportation Plan identified
the risk of flash flooding as a
result of changing precipitation
patterns due to climate change.
• From 1958 to 2011, the Midwest
has seen 45% increase in very
heavy precipitation (NOAA)

Project Objectives
• Better understand the trunk highway network’s risk
from flash flooding
• Identify cost-effect options to improve the network’s
resiliency
• Support the development of Minnesota’s first
Transportation Asset Management Plan (TAMP)
• Provide feedback to FHWA on the Draft Framework

Climate Change & Extreme Weather Vulnerability
Assessment Framework
A guide for transportation agencies to assess
vulnerability to climate change and extreme
weather events
3 key steps:
1. Define study assets and climate
variables
2. Assess vulnerability
3. Incorporate results into decision
making
20
Project Overview
• General systems-level vulnerability assessment
of the trunk highway network in each district
• Timeline: September 2013 – February/March 2014
– Inform and supplement TAMP risk assessment
• Focused adaptation assessment for specific highrisk facilities identified in the system-level
assessment
• March 2014 – June/July 2014
21
Defining Vulnerability
“Climate change vulnerability in the
transportation context is a function of a
transportation system’s exposure to
climate effects, sensitivity to climate
effects, and adaptive capacity.”
(Vulnerability Framework)

Linking TAMP Risk Results and
Adaptability to Climate Change
• Culvert Capacity Risk Mitigation Strategies:
– Check culvert capacity during all capital improvement
projects, upsize when needed, and stop practice of
replacing in kind w/o analysis.
– Identify future projects in advance to do hydraulic analysis,
purchase ROW, and obtain permits. Shelf ready means
incorporation of fixes in short timeframe.
24
Linking TAMP Risk Results and
Adaptability to Climate Change
• Culvert Failure/Collapse Risk Mitigation
Strategies:
– Develop & implement system condition performance
measure for replacement or repair of poor and very poor
culverts
– Culverts in poor and very poor condition are prioritized and
replaced in construction/maintenance projects
25
Key Dates for the TAMP
December 2013 – Expected Federal
Rulemaking for Asset Management
April 2014 - Submittal of Draft TAMP to
FHWA as part of pilot project
October 2015 - MAP 21 Deadline for
Federally Approved TAMP
