> Re-direct flows and impact
downstream users
> Introduce chemicals & increased
turbidity
> Costly repairs
• Supply Reliability> Global warming & rising sea levels

8
• 3 intakes and 34 miles north of Clifton Court Forebay> Each rated at 3,000 CFS
• Main Tunnels> Two tunnels, 40-foot diameter
and 30-miles in length
> Up to 150 feet below ground surface
• Schedule> Construction – 13 years
> Operational by mid-2030s

California WaterFix Benefits
9
• Dual conveyance> Provides operational flexibility
> Allows for operations in a dynamic fishery environment
> Diversion of excess flood flows for dry-year storage & emergencies
• Reduce risks for climate change> North intakes are at a higher elevation
• Improved flow patterns in the Delta> Reduced diversion in the south Delta which lessens reverse flows
> Reduce risk of fish entrainment
• Reduce seismic and subsidence risks> Tunnels are reinforced & below grade
• Improved water quality> Lower total dissolved solids, salinity & bromide

California Eco Restore
10
• Restore and protect +30,000 acres
of Delta habitat by 2020> Restore floodplains, tidal habitat, and aquatic and riparian habitat
• Work in progress:> Restored 1,900 acres of habitat
> 3,900 acres are under construction & 23,200 acres under
permitting
> Restored 1.2 miles of aquatic waterways & planning and permitting
5.5 miles
• Planning & implementation cost $300 million> Funded primarily by CVP and SWP contractors
Pasadena Water and Power
California WaterFix Cost
• Capital cost at $16.7 billion (2017 dollars)> Contingency of 36% or $3.7 billion
> $401 million in capital mitigation
• Operation, maintenance, and mitigation cost> $64.4 million in 2033 (2017 dollars)
> Facilities operational by 2033
• SWP contractors’ cost share at 55%> Negotiating with CVP contractors on cost share
• Metropolitan Water District (“MWD”) is the largest SWP contractor with 45.8% rights> 5 of 29 SWP contractors will not benefit from California WaterFix
> MWD’s cost share ̴ 47.1%

Risks of Not Moving Forward with California WaterFix
• Increasing regulatory constraints> Impacts to water operations result in reduced diversions
> In ability to capture storm flows for drought and emergency supplies
> Threatened fish species requiring higher outflows and decline in water supply
• Threats from earthquakes and subsidence> Levee failures and flooding
> Introduce higher turbidity and chemicals
> Costly repairs
• Climate change> Rising sea levels and introducing higher salinity into water supplies
19
Pasadena Water and Power
Risks of California WaterFix
• Political Risks> Strong opposition challenging the project
� Taking of additional water
� True cost of project & rate impacts
� Alternatives (conservation, recycled water, desalination, storm water capture)
> Potential litigation costs and project delays
• Construction Overruns> Very large and complex project
• Rate Impacts> MWD’s cost allocation is volumetric based
> PWP will always be dependent on MWD imported water
20
Pasadena Water and Power
Local & Regional Water Supply
• Pasadena’s water supply> Local groundwater & spreading credits ̴ 40%
> Imports from MWD ̴ 60%
• MWD’s imported water supply> SWP water provides ̴ 60%
• Preserving investments made in the SWP> City is 1.2% of MWD’s sales
> MWD has 45.8% of rights to the SWP water
• Water Integrated Resources Portfolio> Local resources (groundwater, conservation, recycled water,
stormwater)
• Southern California’s water supply> SWP water ̴ 30%
21

California WaterFix - Conclusion
22
The threat to the water supply and reliability is
greater if no action is taken. California WaterFix
supports the 2009 Delta Reform Act co-equal
goals of improving the State’s water reliability
while protecting, enhancing, and restoring the
Delta ecosystem.
