Delta: Hub of California’s Water Supply
• 25 million Californians• Irrigation for much of the
produce grown domestically• 57 Islands and Tracts• 700 miles of sloughs and
channels• Unique manmade topography

Metropolitan’s share is approximately 25 percentEstimated costs from BDCP Pubic Draft Chapter 8 (Dec 2013) in undiscounted 2012 dollars.
Bay Delta Conservation Plan
• Users pay for new conveyance facility & mitigation• Beneficiaries pay for habitat conservation & statewide benefits • $5 - 6/month per household for Southern Californians

Statewide Economic Report—Costs/Benefits of BDCP
• $5 billion in overall net benefits• 177,000 construction and habitat restoration jobs
created• $84 billion in statewide business activity over
50-year life• Avoidance of water shortages that could cost over
1 million jobs
