A predetermined schedule of sanctions and regulations that reflect both sci
entific knowledge of resources and the preference and judgments of resource
users in the community may provide a useful guide for management decisions
involving complex coastal resource systems. Such a schedule can be impleme
nted by constructing scales reflecting public judgments of the relative imp
ortance of adverse impacts on resources, or of activities causing such impa
cts. The importance scales can then be used to assess existing regulations
and current management priorities and to serve as a guide for revisions and
changes to current practice, for the design of new policy, for rationalizi
ng regulatory controls, and for determining damage awards and other deterre
nce sanctions. The resulting evolution of a schedule can improve the consis
tency of resource use with community preferences by, for example, prescribi
ng more severe restrictions on what are widely agreed to be more serious ha
rms and lesser controls on less important ones. The application of this app
roach is demonstrated using Ban Don Bay, Thailand.
