BDCP: Purpose
Increased reliability
Comprehensive restoration for the Delta
Basis for permits Federal and state endangered species laws
Sources of funding and new methods of decision-making
Adaptive management and monitoring to adjust as conditions change and new information is available
Streamline permitting for projects covered by the plan
Users pay – new conveyance & associated mitigation
Beneficiaries pay – habitat conservation & other state-wide benefits
Average cost for Southern Californians ~ $5 - 6/month per household
Improvements Capital Annual O&M Funding Source

Challenges Replacing SWP Supplies
SWP supplies are essential to alternative supply options
SWP provides baseline supplies that we conserve and recycleSWP provides valuable water quality benefits

Feasibility of alternative supplies
