Community Water Supply Resources Implementation Strategy

Lane Auditorium

Albemarle County Office Building

September 13, 2007

objective of meeting
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.

agenda
Agenda
  • Where We Have Been . . .
  • Implementation Challenges
  • The Resources Challenge
    • Updated Cost Estimates
  • External Requirements
  • Financing Scenarios
  • Next Steps
  • Public Conversation
where we have been
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
where we have been5
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
where we have been6
Where We Have Been . . .
  • Community: Stay in Local “Watershed”
  • Ragged Mountain Alternative “Retooled”
  • Overwhelming Community Consensus
  • Excellent Mitigation Plan
  • Balance: Human Needs and Nature
implementation challenges
Implementation Challenges . . .
  • Prioritization and Financing of Plan Elements
    • Being introduced tonight, followed by future discussions
  • Logistical Issues of Construction
    • Focus of future discussions

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

updated estimated costs
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.

the resources challenge
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
the resources challenge11
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
the resources challenge12
The Resources Challenge
  • Ragged Mountain Dam, Observatory Upgrade, and New Pipelines=$127 Million or 89% of Total $142 Million 50-Year Plan
external requirements
External Requirements
  • Improved Stream Flow Releases
  • Dam Safety Requirement
  • Mitigation Before Impact
  • Safe Yield > Average Day Demand
  • Plant Capacity > Maximum Day Demand
improved stream flow releases
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
dam safety requirement
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
environmental mitigation
Environmental Mitigation
  • Stream and Wetland Mitigation Must Precede Permanent Impacts
  • Permanent Impacts Are In Reservoir Expansion
  • Mitigation Cannot Be Phased
implementation questions
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?
background context
Background/Context
  • Aging Infrastructure
  • Adequacy of Water Supply
  • Present Customers and Future Customers
  • Increasing Regulatory Challenges
  • Local Environmental Objectives
  • Affordability of Urban Area
implementation scenarios
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
phasing the dam
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?
assumptions for scenarios
Assumptions for Scenarios
  • Inflation=2.8%
  • New Debt Terms=30 years @ 5.25%
  • Flow Increase=1.1% per year
  • Equal Annual Principal Repayment
next steps
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
public conversation
Public Conversation

Focus Question:

What are the benefits and challenges of the scenario options?
