    of registered
  • voters in MPWMD area. Conducted by Decision
    Research
  • November 9-11, 2004.
  • Respondents Have A Positive Attitude Toward
    Desalination
  • 75 of respondents say desalination is an
    important
  • potential source of additional water only 15
    oppose
  • Support for The Coastal Water Project (CWP) is
    Strong
  • 74 support the CWP only 19 oppose
  • Respondents Prefer California American Water Over
    Pajaro-Sunny Mesa (PSM) When it Comes to
    Operation of a Desalination Facility
  • 48 prefer California American Water 15 prefer
    PSM and 37 are unsure

Community OutreachMonterey Peninsula Polling
Results
  • Findings based on 500 interviews, random sample
    of
  • registered voters in MPWMD area.
  • Conducted by Decision Research
  • November 9-11, 2004.
  • Respondents Appreciate the Argument that the
    Plant Would Help the Environment
  • 67 agree that a desalination plant would help
    restore the Carmel River Watershed.
  • Need for More Water Trumps Growth Concerns
  • 67 agree more that a desalination plant would
    mean a desperately needed source of water.

23
Position on Coastal Water Project
As you may know, a proposal has been made called
The Coastal Water Project to address the water
supply needs on the Monterey Peninsula. This
proposal would mean building a desalination plant
in Moss Landing and an underground water storage
facility in Seaside, both of which would be
completed in about five years. Generally
speaking, do you favor or oppose this proposal as
a way of meeting the regions water supply needs?
