Fairweather’s Future: A Sustainable Water Supply

1. Fairweather’s Future: A Sustainable Water Supply LNNC Consulting December 17, 2001

2. LNNC Planning Team

3. Today’s Agenda • Fairweather Background • Status Quo - Existing System • Opportunities • Goals & Planning Objectives • Stakeholder Involvement • STELLA Shared Vision Model • Performance Metrics • Actions to Consider • Special Considerations • Alternatives • Final Recommendation

4. Fairweather Background • Supply Sources • Blue Reservoir • Green Reservoir • Aquifer - Ground Water (up to 10MGD) • System Constraints • Existing system unable to meet current demands • Expected growth and increased instream flow requirements jeopardize future reliability • Weakened leadership in Water Department and little communication between concerned parties

5. Fairweather Status Quo: Current Supply & Demand

6. Opportunities • Develop a 25-Year Plan • Develop a network of people sharing a common set of goals • Organize a Watershed-focused Water Resources Management Team • Increase protection of natural resources with emphasis on conservation

7. Planning Goals • Provide safe and reliable water while protecting and enhancing our natural resources • Establish a planning framework in which stakeholders will contribute to all phases of the planning effort

8. Planning Objectives • To provide safe and reliable water • To provide quality service at a reasonable cost • To protect surface and groundwater supplies, while sustaining and enhancing the regions natural resources • Educate and inform all partners about water use, conservation, and water reclamation options • Incorporate flexibility in the plan • Develop world-class management

9. Involvement of Public and Stakeholders in the Planning Process • Who are the stakeholders? General public, purveyors, city utilities, NGO’s, governmental agencies • Steps taken to involve stakeholders Media campaign, representation on the planning committee, public meetings for comments, promotional literature, website, feedback to stakeholders on project development.

10. STELLA Shared Vision Model • Applicability of Stella: • Model that incorporates the collective vision of stakeholders into development, implementation and maintenance of the plan • How the Model is Used for Planning: • Dynamic projections of planning solutions • Accessible, transparent, for all stakeholders • Analysis performed at different time stages of the alternative • Flexible - able to adjust to new inputs

11. Developing Performance Metrics • Model Metrics • Annual Reliability, Cumulative Amount of Shortfall Volume, Annual Water Bill, Present Day Cost, Fish Stress Level and Fish Vitality, Quantity/Quality of Recreation, Conservation • Qualitative Metrics • Flexibility, Public Acceptance, Efficiency

12. Actions to Consider

13. How Individual Actions Increase Safe Yield (98%)

14. How Individual Actions Reduce Demand

15. Considerations When Reviewing Actions • Anticipated Increased Fish Flows by 50% • Population Growth Rate of 3% • Curtailments and Conservation • Model is based on recent historical record only • Climate Change

16. Principles for Combining the Actions to Form Alternatives • Pre-screening with emphasis on feasibility, reliability values • Strategy of heavy conservation • Cost-benefit estimates

17. 4 Alternatives Selected Alternative 1: Conservation, Seasonal Pricing II, Small Blue Expansion Alternative 2: Conservation, Seasonal Pricing I, Yearly water Bill Increase, Groundwater Expansion to 20MGD Alternative 3:Conservation, Seasonal Pricing I, Groundwater Expansion to 20MGD, Small Blue Expansion Alternative 4:Conservation, Water Reuse, Seasonal Pricing II, Yearly Water Bill Increase

18. Ranking of Alternatives • Graphs of Demand and Increases of Safe Yield • How much time does each alternative “buy” • Comparisons of Alternatives’ metric performance • Model Metric Ranking • Qualitative Ranking

19. Conservation, Seasonal Pricing II, Small Blue Expansion Seasonal Pricing II Small Blue Exp

20. Conservation, Seasonal Pricing I, Yearly water Bill Increase, Groundwater Expansion to 20MGD GW – 20MGD Seasonal Pricing I Yearly Price Increase

21. Conservation, Seasonal Pricing I, Groundwater Expansion to 20MGD, Small Blue Expansion Small Blue Exp GW – 20 MGD Seasonal Pricing I

22. Conservation, Water Reuse, Seasonal Pricing II, Yearly Water Bill Increase Water Reuse Seasonal Pricing II Yearly Increase

23. Ranking Results for 2025 • Model Ranking Results  Alternative 2 has highest score • Based on the Qualitative Criteria of Flexibility, Efficiency,World-Class Management and Political Acceptability, Alternatives 2 and 4 received the highest score.

24. Final Alternative Recommendation Alternative 2: conservation, seasonal pricing I, yearly water bill price increase, groundwater pumping

25. Implementation of Final Recommendation GW – 20MGD Seasonal Pricing I Yearly Price Increase

26. Suggestions for Continued Planning • 5 Year Reviews of Plan(s) by Planning Committee • Continued Communication with Stakeholders • Incorporating Regular Information Updates into Model
