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

threatened– Seismic– Sea-level rise– Subsidence

TOTAL Capital/O&M $19.85 billion $4.90 billion

TOTAL BDCP $24.75 billion

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
