Non-Hydrological Benefits And Citizen Preference

Determine qualitatively which aspects of green versus gray infrastructure matter to citizens. For example, citizens may care about tree cover, but not about permeable paving. Measure the value that citizens place on salient attributes of green infrastructure. Values are defined by the tradeoffs that citizens are willing to make. If a citizen will accept higher costs (in the form of house price or association fees) in order to get more of an amenity, than the marginal value of the amenity is defined as the tradeoff ratio the citizen is willing to make. Recently developed methods such as the stated choice method allow simultaneous measurement of several different attributes. Information on which attributes are highly valued by citizens, which have low value, and which have negative value will help determine the degree to which it is possible to design green infrastructure systems that meet water management objectives while providing the highest possible nonhydrological benefits.
