Appendix 2: Proposed Choice Experiment Design

Description of variables:
x1 = North Full Body Contact: 2 levels. Current Condition is level 1, or safe wading only
x2 = South Full Body Contact: 2 levels. Current Condition is level 1, or safe wading only
x3 = North Flow & Forest: 3 levels. Current Condition is level 3, Expected Future is level 1
x4 = South Flow & Forest: 3 levels. Current Condition is level 3, Expected Future is level 1
x5 = Cost to household per year, 6 levels. Cost options range from zero (Expected Future and level 1), $10, $20, $30, $40, and $60 (level 6)

Nine survey blocks are proposed, of four choice questions (sets) each. The third alternative is always the Expected Future, no cost alternative.
