2 Condition Risk Assessment Assessment Risk is the uncertainty that impacts our operations. It can take the shape of Manpower, Funding, Weather, Materials, Policies, and Equipment. Eight Elements of Asset Management Cost Data Performance Measures Risk Replacement Model 2

3 Risk What is Risk and what is Our Goal: Risk Risk management is the cultures, processes and structures that are directed towards the effective management of potential opportunities and threats Risk = Function(Threats * Vulnerabilities * Impacts * Velocity) Goals Become More Proactive through Risk-Informed Processes and Mitigation Plans, Capitalize on Opportunities Continue to build public trust 3

4 Risk Assessment Risk Assessment the Basics The risk management process should consist of four important parts: Identifying risks that could impact the Operations/Asset Management Plan Assessing the likelihood and impact of such variance Responding by developing plans for minimizing hazard and maximizing gain Managing the execution of those plans 4

5 Responding to Impacts of Risk Responding to Impacts After assessment of consequences, next step is an evaluation of strategies to minimize impacts Avoid Reduce Transfer Accept 5

6 Decision Tree 6

7 Types of Risk 7

8 Short Term Risk Examples Programmatic - Project Seasonal 8

9 Long Term Risk Examples Funding Down Stream Effect 9

10 Focus on Short Term Risk Programmatic - Project Seasonal 10

11 Short Term Risk Roadside Examples of Risk: Fire Danger Equipment Breakdown Early, Late or Extended Growing Season 11

12 Short Term Risk Roadside Fire Danger: Increase Cost Water Trucks Shorted Work Hours Increases Time Needed to Complete Safety Examples of Risk: Fire Danger Equipment Breakdown Early, Late or Extended Growing Season 12

13 Short Term Risk Roadside Down Equipment: Increase Time Less Equipment Available to Perform the Work Increases Time Needed to Complete Examples of Risk: Fire Danger Equipment Breakdown Early, Late or Extended Growing Season Safety 13

14 Short Term Risk Roadside Early, Late or Extended Growing Season: Variable Cost Safety Shorter Season Canwork on other High Priority Work Orders Extended Season Cannotwork on other High Priority Work Orders Examples of Risk: Fire Danger Equipment Breakdown Early, Late or Extended Growing Season 14

15 Roadside Risk Treatment Treatment Prior to 2015: Added Water Trucks Accepted Increased Cost for the Program Shortened Working Hours Accepted Stop work by 1pm and be on fire watch Rented ADDTL Tractors if available Accepted Supplement Down Equipment Increased Cost for the Program Finish Program more quickly Increased Cost for the Program Examples of Risk: Fire Danger Equipment Breakdown Early, Late or Extended Growing Season 15

16 Roadside Risk Treatment Current: Utilize AGO to create an Inventory of where we need to cut and where we have obstructions to the IVM program In the winter we put a crew together to remove the obstructions that can be removed Reduced Vegetation crew can now see where the remaining obstructions are so we reduce the risk of damaged equipment Examples of Risk: Fire Danger Equipment Breakdown Early, Late or Extended Growing Season Utility Marker Fire Hydrant 16

17 Roadside Risk Treatment Current: This Dynamic Inventory has changed our IVM Program by: Slight Initial Increased Cost for the Program Accepted Dramatic decrease in time to complete one cut cycle (months) Reduced Completed two passes in the time it took to complete one pass Identify areas for brush cutting vs mowing to maximize equipment Mitigated Show Owner Will Maintain Location to reduce citizen complaints Mitigated Examples of Risk: Fire Danger Equipment Breakdown Early, Late or Extended Growing Season 17

18 Short Term Risk Catch Basin Cleaning Examples of Risk: Out of Permit Compliance Localized Flooding 18

19 Short Term Risk Catch Basin Cleaning Out of Permit Compliance: Requirements Catch Basin Inspection Annually Cleaning within 6 month of inspection Water Quality Flow Control (Annual and per 10 year event) Inspection Annually Cleaning within 12 month of inspection Examples of Risk: Out of Permit Compliance Localized Flooding 19

20 Short Term Risk Catch Basin Cleaning Localized Flooding: Increase Cost Safety Fighting water while cleaning Potential for additional material to be in catch basin Water Over the Roadway Examples of Risk: Out of Permit Compliance Localized Flooding 20

21 Catch Basin Risk Treatment Current: We started out with 4 teams of 2 to inspect catch basin and saw a trend early in the inspection process that we were having to clean a lot of catch basins. To lengthen the time line to get them cleaned I reduced the number of inspection teams Reduced Examples of Risk: Out of Permit Compliance Localized Flooding Last November/December Pierce County had two 10 year event rainfall totals Saw an increase in the amount of material in the WQFC features Accepted 21

22 Blending Critical Assets and Risk Likelihood vs Impact Scale Likelihood Chance that something happens Impact Outcome of an event 22

23 Future Risk Assessments Criticality Matrix Likelihood Stormwater Pipe Characteristics: Length Likelihood vs Impact for Assets: Reprioritize WO s Diameter Material Wall Type Road Grade Soil Type Flooding history 23

24 Future Risk Assessments Impact Stormwater Pipe Characteristics: Land Zone Type Likelihood vs Impact for Assets: Reprioritize WO s Sensitive Area Road Classification Lahar Evacuation Route Pipe Type 24

25 Inventory Other ways to define Critical Assets Replacement Value Location to other infrastructure Lifeline Routes Hospitals Shelters Lahar Evacuation Routes Primary Arterials 25

26 Inventory Thoughts to take away This is nothing new. Everyone uses Risk Analysis every day, every time you make a decision. Our experience with enterprise asset management programs can identify, summarize risks but lack a comprehensive planning tool for dynamic assets. Addressing risk adds realism, credibility to asset management programs 26
