BDCP Road Map

BasicsIntroduction:  New to the Bay Delta Conservation Plan?  Start here for a brief overview of the project, plus links to other summary documents and helpful materials.  Introduction

Regulatory Context:  Look to this page for information on habitat conservation plans, federal and state endangered species regulations, permits, compliance, monitoring, covered activities, geographic scope, and the BDCP’s relationship to other Delta planning efforts. The BDCP’s Regulatory Context and Its Relationship to Other Plans

Existing and historical conditions: The Delta’s existing and historical ecological conditions are detailed here: Existing and Historical Conditions


Conservation StrategyConservation Strategy:  Just what exactly are the specific outcomes the BDCP is striving to achieve, and how does it plan to do that?  Find out about covered species, biological goals and objectives, conservation measures, and adaptive management on this page:  Conservation Strategy

Conservation Measures:The Conservation Measures are the specific actions that the BDCP will take to achieve the goals and objectives of the project.  Learn the specifics about the BDCP’s 22 Conservation Measures here:  Conservation Measures

New Water Infrastructure – the Twin Tunnels:  Cut to the chase and find all the plan documents related to the new water infrastructure (also known as Conservation Measure 1), including a description of the new facilities,their costs, project operations, flow, decision tree, and the tunnel route on this page:  Conservation Measure 1

Ecosystem Restoration:  The BDCP is proposing to restore and protect 145,000 acres of habitat throughout the Delta.  The different types of habitat to be restored, the implementation schedule, why habitat restoration is expected to help native species, and early implementation projects are detailed on this page:  Ecosystem Restoration

Adapting to Climate Change:  How climate change is incorporated into the BDCP is primarily detailed in Chapter 29 of the environmental documents, but in other places as well.  Find out about greenhouse gas emissions, sea level rise, the impacts expected for the Delta’s natural communities and native species, and its effect on reservoir operations and temperature control on this page:  Climate Change


Managing the PlanGovernance and Implementation of the Plan:  Go to this page for information on the roles and responsibilities of all the entities involved in BDCP implementation, the function of the Implementation Office, how the plan will be implemented and reporting requirements:  Governing and Implementing the Plan

Adaptive Management:  The BDCP is a 50-year plan, and it’s likely changes are going to be necessary.  When conservation measures don’t go as expected and changes need to be made, adaptive management is the mechanism for making changes.  Find out how adaptive management is incorporated into the Plan on this page:  Adaptive Management

Project Costs and Funding:  How much is all of this going to cost?  And who is going to pay for it?  That is detailed on this page:  Project Costs and Funding

Economic Analyses:  To date, the state has produced two different economic analyses for the plan, which others have disputed.  Find out more about the economic analyses on this page:  Economic Analyses


ImpactsBiological impacts: The Effects Analysis describes how the BDCP’s actions will affect the Delta’s ecosystems, natural communities, and covered species, and presents conclusions on the outcomes from implementing the conservation strategy.  It does not replace the environmental analysis required under NEPA/CEQA.  For more on the Effects Analysis, go here:  Effects Analysis: Analyzing the biological impacts of the plan

Environmental Impacts:  The environmental impact report analyzes impacts to the Delta’s natural resources.

  • For more on the impacts of implementing the BDCP on water supply, surface water, groundwater, water quality, geology and seismicity, soils, fish and aquatic resources, terrestrial biological resources, land use, agricultural resources and recreation, visit this page:  Environmental Impacts of the Tunnel Plan Part 1 
  • For impacts on terrestrial biological resources, land use, agricultural resources and recreation, visit this page:  Environmental Impacts of the Tunnel Plan Part 2
  • For information on the impacts to socioeconomics, aesthetics and visual resources, cultural resources, transportation, public service and utilities, energy, air quality and greenhouse gases, noise, hazards and hazardous materials, public health, mineral resources, paleontological resources, environmental justice and growth inducement, see this page:  Environmental Impacts of the Tunnel Plan Part 3
  • For information on the impacts to air quality and greenhouse gases, noise, hazards and hazardous materials, public health, mineral resources, paleontological resources, environmental justice and growth inducement, see this page:  Environmental Impacts of the Tunnel Plan Part 4

Environmental commitments:  During implementation of the BDCP,  the environmental commitments listed in Appendix 3B will be incorporated into the plan to avoid or minimize potential adverse and significant impacts.  While some of the commitments may or may not be required by regulating agencies,  these commitments will be satisfied even if not separately imposed by the permitting agencies. If permitting agencies require additional measures, those will be adhered to as part of the permits.  Environmental commitments include using best management practices, developing and implementing control plans for sediment, barge operations, and fish rescue/salvage.  They also include enhancing recreation access in vicinity of the intakes, funding the recreation recommendations included in the Delta Plan, funding aquatic weed control, and management of selenium.  Find out more about the environmental commitments here:  BDCP EIR-EIS Appendix 3B – Environmental Commitments


Alternatives‘Take’ Alternatives:  It is a requirement of habitat conservation plans that the permit applicants must specify alternatives that would result in take (mortality) levels less than those anticipated by the proposed action or alternatives that would result in no take (mortality), and to explain why these alternatives were not chosen.  Accordingly, the alternatives in this chapter are analyzed for this narrow and specific regulatory purpose, which is separate from the analysis of project alternatives required under CEQA and NEPA.   Look for more information here:  Alternatives to Take

EIR Alternatives:  The Draft EIR/EIS considers 15 action alternatives, including the proposed BDCP (twin tunnels), and one no-action alternative. The alternatives analyzed in the draft EIR/EIS include a combination of water conveyance configurations, capacities and operational criteria; conservation measures that include habitat restoration
and conservation targets and stressor reduction measures; and various avoidance and minimization measures.  Find out more about those here:  EIR Alternatives

Other Proposals:  Other groups and organizations have proposed their own alternatives to the BDCP.  Find out about them on this page: Other Proposals
