Abstract: From ground level observations of local weather patterns, topographic features and vegetation, avalanche paths can be reliably identified and return probabilities for potentially destructive avalanches estimated. Using physical and statistical models, reasonable estimates of maximum runout distances and impact forces for avalanches can be projected. What remains a mystery is how to balance public safety and the rights of private property owners to build and develop land in or near areas identified as being prone to avalanches. Between 1982 and 1986 several severe avalanche cycles in the Sierra Nevada forced public planners in four neighboring counties of California and Nevada to consider enacting avalanche ordinances for their respective municipalities. Studies were conducted by qualified avalanche consultants and maps were drawn clearly identifying potential avalanche areas. While these counties are geographically similar, and the nature of avalanche phenomena observed in each county virtually identical, the solutions enacted by public policy makers in each county have ranged from overreaction to no action at all. This paper explores the decision making processes observed in each county as planners, politicians and the public have grappled with the ramifications of enacting avalanche ordinances.
