2. Week 8 we discussed 3 main sources of imported water that Los Angeles relies on to serve its residents. Please choose one of these sources of water and discuss the following:

C. If you were put in charge of your chosen facility, what would you do to secure future water deliveries from this source of water? In other words, what would you do to help ensure that future deliveries would not be threatened by droughts or any other possible events?
D. Choose one thing you would do as Mayor of Los Angeles to reduce the amount of water Angelinos use at home – your one thing should be what you think would make the biggest impact in terms of reducing the amount of water the City has to deliver to single family homes (do not worry about apartments/condos/townhomes).
