1 City of San Diego Asset Management: Citywide and Watershed Based Approach Society of American Military Engineers November 13, 2013 Gene Matter, P.E. Senior Civil Engineer City of San Diego Storm Water Division

2 Agenda Where the City was EAM Committee & Standardized Citywide AM Guideline Watershed Asset Management Plan Lessons Learned What s Next 2

3 Where the City was 2005 READ 4430 parcels Not All Accounted For 3

4 Where the City was Failing Infrastructure General Fund vs Enterprise Fund 4

5 Where the City Was Asset Owning Departments Decentralized assets Funding source Operating in Silos 5

6 EAM Committee Enterprise Asset Management Committee 2010 Asset Managers, Engineers, Analysts, Facilities Managers Standardize AM practices 6

7 EAM Committee Develop Asset Registry Roads, pipes, parcels, trees, docks, boats, etc List of Attributes Wow there were inconsistencies Road suffix, pipe diameter 7

8 Standardized Citywide AM Guideline Discuss AM practices amongst Asset Owning Departments Non existence to Advanced Develop a policy or guideline AM will begin when need and resources meet 8

9 Standardized Citywide AM Guideline 10 Steps to Develop an Asset Management Plan Develop Asset Registry Assess Condition, Failure Modes Determine Residual Life Determine Life Cycle & Replacement Costs Set Target Levels of Service (LOS) Determine Business Risk ( Criticality ) Optimize O&M Investment Optimize Capital Investment Determine Funding Strategy Build AM Plan 9

10 Watershed Asset Management Plan 10 Deferred Capital Bonding Program Adopted 5/8/13, in effect 6/27/13 Water Quality Improvement Plans in 2 years (June 27, 2015) Key Changes: Outcome-based requirements Watershed water quality focus Adaptive management Integrates storm water regulations (TMDLs)

11 Watershed Asset Management Plan Mission, Goals, LOS Flood Risk Management & Water Quality Improvement Which assets needed to achieved LOS? Hard, Soft and Natural Assets 11

12 Watershed Asset Management Plan 12

13 Watershed Asset Management Plan Full life cycle (100 Yr) costs Hard Assets Flood Risk Management Soft Assets Permit related activities Natural Assets CLRP related activities Helps prioritize projects based on Business Risk Exposure Condition, Reliability, Performance Probability of Failure (PoF) Triple Bottom Line Consequences of Failure Consequence of Failure (CoF) Business Risk Exposure 13 PoF x CoF = BRE

14 14 Risk Score Results For Stormwater Pipelines

15 15 Activity Prioritization

16 Green Streets Modeling City of San Diego, 43 rd & Logan Green Street 64% streets feasible Used pilot designs, data Permeable pavement Bioretention 16

17 Green Streets Spatially optimized Priority subwatersheds identified 17 17

18 Total Investment Need (Million) Watershed Asset Management Plan $250 5 Year Outlook $212 $200 $185 $150 $100 $109 $132 $120 $50 18 $ HardAssets Soft Assets Natural Assets (Flood Risk Management) (Permit) (CLRP)

20 Lessons Learned End user is decision maker Carry forward budget Review staff inputs in model 20

21 Lessons Learned Confidence Level Rating 21

22 What s Next Refine model and assumptions Continued assessments Work with stakeholders and decision makers 22

23 23 What s Next Historical Approach to Renewal Planning Risk-Based Renewal Planning Backward Looking Budget Based on Last Year Little knowledge of system risks Forward Looking Based on asset risk scores throughout system and long term forecasts of risk and cost Reactive Projects determined as problems arise during the year Proactive High risk assets slotted for renewal before failure occurs Budget Constrained Do as many projects as you can afford each year Risk or Budget Constrained Budget could be determined based on agreed risk targets for system Ignores asset and system risks Money is spent but overall risk may not have been reduced much Focused on risk management High risk assets addressed first Budget may rise or fall to meet risk targets
