Bringing it All Together

• Applying critical infrastructure tools:1. Delineate important assets and gather data

2. Estimate future travel and economic activity

3. Solicit stakeholder input and develop a critical infrastructure consensus

• Defining criticality excludes engineering and environmental considerations

• Outputs Feed Assessment during Task 2 efforts



17

• ICF and PB will develop a preliminary list of critical assets Review MPO Model & other available modal or special purpose models

• Enhance models as needed to identify critical infrastructure & assess vulnerability

• Re-run model as needed to test critical links (stress on system if one link down)

Review plans & programs, interview staff Collect & review asset data & asset management tools in use

• Score and rank critical assets

• Send draft critical asset list to climate workgroup to request feedback



18

• Collect, review, and summarize climate/weather data to develop datasets of past and future conditions

Observations and model projections• temperature • precipitation• winds • runoff• waves • sea level rise• storm surge• will examine changes in both means and extremes

Approach will be different than Phase I, e.g.• focused explicitly on Mobile• use of more advanced models (e.g., ADCIRC; downscaling)• provide near-term, mid-term, and end-of-century futures

One illustrative output will be GIS-based maps indicating potential inundation

• incorporating: global sea level rise, local subsidence, LIDAR-based elevation, and storm surge modeling

Task 2: Identify Climate DataTask 2: Identify Climate Data

19

• Develop qualitative assessments of the sensitivity of critical transportation infrastructure and services in Mobile to climate

Parametric modeling – time series analysis Analog analysis – assessment of extreme events. Guidance from the CC

Work Group is requested.• Katrina (other?)• Heat wave (2007?)• Non-hurricane-related storm (?)

Infrastructure cost analysis

• For this to be as useful as possible to Mobile we need relevant transportation data for:

Bridges Highways Tunnels Railroads Marine ports and terminals

Task 2: Identify Climate SensitivityTask 2: Identify Climate Sensitivity

• Waterways

• Airports

• Bicycle and Pedestrian infrastructure

• Public Transportation

• Natural Gas and Oil Pipelines 20

Task 2: Identify Climate SensitivityTask 2: Identify Climate Sensitivity

• Data types, e.g. Asset value; replacement cost

• Includes infrastructure and equipment

Maintenance and repair frequency and cost• Including in relation to other costs/values

Post-weather-event survey – damage estimate; service loss Insurance claims Asset monitoring – e.g.

• Condition, projected life span, etc.

Travel information – e.g.• VMT, transit time, avg speed, accident data, etc.

Value and quantity of goods transported• roadway, marine, air, pipeline

Regional/national economic dependence on Mobile transportation• transportation through and out of the region

We need your help! Names, web sites, documents, etc.

21

Data Needs: Task 1 vs. Task 2Data Needs: Task 1 vs. Task 2

• Tasks 1 and 2 will mostly rely on similar data, e.g.: vehicle miles traveled freight value

• Some data will be exclusively for a specific task, e.g.:

Task 1—specific location Task 2—historical damage to assets

• Some data will later be useful for Task 3, e.g.: Engineering specifications of a particular asset

22

Next StepsNext Steps

• Task 1: Develop draft list of critical transportation assets in Mobile Share list with Climate Work Group and ask for feedback

• Task 2: Follow up to pursue access to particular data Interview key individuals regarding impacts from past weather

events Present preliminary results from sensitivity analysis to receive

feedback from the Climate Work Group
