  1. Community Water Supply Resources Implementation Strategy Lane Auditorium Albemarle County Office Building September 13, 2007

  2. Objective of Meeting Tonight’s objective is to begin a dialogue with our community and its leaders regarding the priorities and the financial challenges and opportunities in implementing our Community Water Supply Plan.

  3. Agenda • Where We Have Been . . . • Implementation Challenges • The Resources Challenge • Updated Cost Estimates • External Requirements • Financing Scenarios • Next Steps • Public Conversation

  4. Where We Have Been . . . • 32 Water Supply Alternatives Screened • Comprehensive Alternative Analysis • Rigorous & Extensive Federal & State Legal Requirements • 9 Previous Public Meetings Since September 2004 – Significant Public Input

  5. Where We Have Been . . . • Context of Selecting Preferred Alternative: • “…least environmentally damaging, practicable alternative…” • What’s Best for Local Community as a Whole • Cost Was Not the Primary Driver • RMR Alternative is Cost-Effective • RMR Alternative Amenable to Phasing

  6. Where We Have Been . . . • Community: Stay in Local “Watershed” • Ragged Mountain Alternative “Retooled” • Overwhelming Community Consensus • Excellent Mitigation Plan • Balance: Human Needs and Nature

  7. Implementation Challenges . . . • Prioritization and Financing of Plan Elements • Being introduced tonight, followed by future discussions • Logistical Issues of Construction • Focus of future discussions

  8. In preparing for battle, I have always found that plans are useless, but planning is indispensable. -Dwight D. Eisenhower Great minds discuss ideas; average minds discuss events; small minds discuss people. -Eleanor Roosevelt The only way not to think about money is to have a great deal of it. -Edith Wharton

  9. Updated Estimated Costs • Ragged Mountain Dam • Observatory Upgrade to 8 MGD and Piping • SFRR Pipeline • South Fork Expansion to 16 MGD • Observatory Expansion to 10 MGD $37.2 Million $34.0 Million $55.9 Million $127.1 Million $ 9.0 Million $ 6.0 Million $142.1 Million Note: All Estimates are in 2007=$. Estimates Subject to Change with Inflation.

  10. The Resources Challenge • Existing RWSA Depreciated Water Assets: $79 Million • “Prorated” RWSA Water System ~ $33.5 Million • Proposed Community Water Supply (CWS) Plan=$142 Million (2007=$) • CWS Plan Alone is 424% of Current Total Water Assets!! • Additional $11 Million in Urban Water Needs Identified in 5-Year CIP Outside CWS

  11. The Resources Challenge • Existing Debt (Water and Wastewater)=$54 Million • Anticipated Debt for CWS Plan Alone is 263% of Current Total RWSA Debt!! • Wastewater Needs and Water Distribution Needs Will Further Add Substantially Greater Debt over Next 5-10 Years

  12. The Resources Challenge • Ragged Mountain Dam, Observatory Upgrade, and New Pipelines=$127 Million or 89% of Total $142 Million 50-Year Plan

  13. External Requirements • Improved Stream Flow Releases • Dam Safety Requirement • Mitigation Before Impact • Safe Yield > Average Day Demand • Plant Capacity > Maximum Day Demand

  14. Improved Stream Flow Releases • Extensive Work with TNC and DEQ • Future Flow Past the Dam Will More Closely Mimic Natural Conditions • Significantly Improves Stream Flow During Drier Periods • Provides for Two Conditions • After New Full Height RMR Built • After SFRR Pipeline Built

  15. Dam Safety Requirement • Existing Ragged Mountain Dams Built in 1885 (Upper) and 1908 (Lower) • Existing Dams Do Not Meet Current Safety Requirements • Virginia Dam Safety = 2011 Mandate • Design of New RMR Dam Already Underway

  16. Environmental Mitigation • Stream and Wetland Mitigation Must Precede Permanent Impacts • Permanent Impacts Are In Reservoir Expansion • Mitigation Cannot Be Phased

  17. Safe Yield > Average Day Demand

  18. Plant Capacity v. Maximum Day Demand

  19. Implementation Questions • How Much Can We Afford to Build Right Away? • Is a Phased Implementation Needed? • What Are Our Priorities? • How Do We Pay for the Plan?

  20. Background/Context • Aging Infrastructure • Adequacy of Water Supply • Present Customers and Future Customers • Increasing Regulatory Challenges • Local Environmental Objectives • Affordability of Urban Area

  21. Implementation Scenarios • Scenario 1: Build Full Dam and SFRR Pipeline Now • Scenario 2: Phase Dam and Build SFRR Pipeline Now • Scenario 3: Build Full Dam Now and Phase SFRR Pipeline

  22. Phasing the Dam? • If Ragged Mountain Dam Phased, SFRR Pipeline Required at Time of First Phase to Meet DEQ Flow Past the Dam • Phasing Dam Requires Higher Early Year Capital Costs • Building Dam in One Phase Improves Structural Integrity (Seepage) • Dam Construction Has Major Logistical Challenges – How Much is Too Much?

  23. Assumptions for Scenarios • Inflation=2.8% • New Debt Terms=30 years @ 5.25% • Flow Increase=1.1% per year • Equal Annual Principal Repayment

  24. Next Steps • Public Conversation Tonight • Follow-Up with Agencies on Permit • Continue with Ragged Mountain Dam Design to Meet Dam Safety Deadline • Further Conversations on Resource Implementation Plan

  25. Public Conversation Focus Question: What are the benefits and challenges of the scenario options?
