Risk Assessment

Risk is the uncertainty

that impacts our

operations. It can take

the shape of Manpower,

Funding, Weather,

Materials, Policies, and

Equipment.

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 trust3

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

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

Short Term Risk – Roadside

11

Examples of Risk:

• Fire Danger

• Equipment Breakdown

• Early, Late or Extended Growing Season


12

Examples of Risk:

• Fire Danger



Fire Danger:

Increase Cost

• Water Trucks

• Shorted Work Hours

Increases Time Needed to Complete

Safety


13

Examples of Risk:

• Fire Danger



Down Equipment:

Increase Time

• Less Equipment Available to Perform the Work

• Increases Time Needed to Complete

Safety


14

Examples of Risk:

• Fire Danger



Early, Late or Extended Growing Season:

Variable Cost

• Shorter Season – Can work on other High Priority Work Orders

• Extended Season – Cannot work on other High Priority Work Orders

Safety

Roadside – Risk Treatment

15

Examples of Risk:

• Fire Danger



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


16

Examples of Risk:

• Fire Danger



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

Fire Hydrant


17

Examples of Risk:

• Fire Danger



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

Short Term Risk – Catch Basin Cleaning

18

Examples of Risk:

• Out of Permit Compliance

• Localized Flooding


19

Examples of Risk:



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


20

Examples of Risk:



Localized Flooding:

Increase Cost

• Fighting water while cleaning

• Potential for additional material to be in catch basin

• Water Over the Roadway

Safety

Catch Basin – Risk Treatment

21

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

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

Examples of Risk:



Likelihood vs Impact Scale

Likelihood

• Chance that something happens

Impact

• Outcome of an event

Blending Critical Assets and Risk

Future Risk Assessments – Criticality Matrix

23

Likelihood Stormwater Pipe Characteristics:

• Length

• Diameter

• Material

• Wall Type

• Road Grade

• Soil Type

• Flooding history

Likelihood vs Impact for Assets:

• Reprioritize WO’s

Future Risk Assessments

24

Impact Stormwater Pipe Characteristics:

• Land Zone Type

• Sensitive Area

• Road Classification

• Lahar Evacuation Route

• Pipe Type

Likelihood vs Impact for Assets:

• Reprioritize WO’s

Inventory

Other ways to define Critical Assets

• Replacement Value

• Location to other infrastructure

• Lifeline Routes

• Hospitals

• Shelters

• Lahar Evacuation Routes

• Primary Arterials

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
