3 2002 CWS Strategy and Need to Update

4 Basic Components of February 2002 Community Water Supply Strategy Capital Improvements Capital Improvements Water Conservation Water Conservation Watershed Protection Watershed Protection Environmental Protection Environmental Protection

5 2002 Strategy – Capital Improvements SFRR Four-Foot Crest SFRR Four-Foot Crest SFRR Dredging SFRR Dredging Restore Mechums River PS and Increase Supply in Ragged Mountain Restore Mechums River PS and Increase Supply in Ragged Mountain James RiverJames River Beaver CreekBeaver Creek Reservoir Reservoir Other CapitalOther Capital Options Options 30-Year50-Year

6 The Need to Update New Drought of Record in 2002 New Drought of Record in 2002 Improved Modeling Information Improved Modeling Information Lower Yield for Four Foot CrestLower Yield for Four Foot Crest Uncertain Costs and Yield for DredgingUncertain Costs and Yield for Dredging DECISION: Update the Capital Improvement Options in the Community Water Supply Plan Based on 50-Year Horizon

7 Update - So Far Existing Water Supply Adequate Until 2008 Existing Water Supply Adequate Until 2008 Use of Beaver Creek in Drought Can Extend Adequacy to 2018 Use of Beaver Creek in Drought Can Extend Adequacy to 2018 Safe Yield Deficit in 2055 – 9.9 MGD Safe Yield Deficit in 2055 – 9.9 MGD

9 The Goal

10 Obtain a Federal Permit That... Obtain a Federal Permit That... – Will Achieve 9.9 MGD of Added Capacity Over 50 Years –Acceptable to State and Federal Regulators –Acceptance to Local Community –Issues are Complex and Cross the Jurisdiction of Multiple Agencies Jurisdiction of Multiple Agencies

11 Federal and State Requirements Water Quality Water Quality Wetland Impacts Wetland Impacts Stream Impacts Stream Impacts Stream Flows for Expanded Reservoirs Stream Flows for Expanded Reservoirs Threatened and Endangered Species Threatened and Endangered Species Cultural Resources Cultural Resources Recreational Resources Recreational Resources Highway and Bridge Issues Highway and Bridge Issues To identify the least environmentally damaging, practicable alternative taking into account: overall project purposes, feasibility, logistics, and cost. Specific Issues That Must Be Addressed:

12 Federal and State Agencies U.S. Army Corp of Engineers Norfolk District U.S. Army Corp of Engineers Norfolk District U.S. Environmental Protection Agency Region III U.S. Environmental Protection Agency Region III U.S. Fish and Wildlife Service U.S. Fish and Wildlife Service Virginia Department of Environmental Quality Virginia Department of Environmental Quality Virginia Department of Health Virginia Department of Health Virginia Department of Game and Inland Fisheries Virginia Department of Game and Inland Fisheries Virginia Department of Conservation and Recreation Virginia Department of Conservation and Recreation Division of Planning and Recreation Virginia Marine Resources Commission Virginia Marine Resources Commission Virginia Department of Historic Resources Division of Virginia Department of Historic Resources Division of Resource Services and Review Virginia Department of Conservation and Recreation Virginia Department of Conservation and Recreation Division of Natural Heritage
