In recent years, negative media attention has fostered the impression that Federal Emergency Management Agency (FEMA) parks are social wastelands filled with criminal elements and other undesirables. FEMA parks have subsequently come to be viewed by some as a major threat to the safety and quality of life of the local communities in which they are situated. This analysis addresses attitudes toward FEMA trailer parks in Baton Rouge after Hurricane Katrina among Baton Rouge residents. Drawing on the Locally Undesirable Land Use=Not in My Backyard (LULU=NIMBY) literature, the contact hypothesis, and a broad paradigm of social status and social control, we hypothesize that spatial proximity, contact, and social status will influence negative perceptions of the parks, while these same factors along with the negative perceptions will influence avoidance behaviors. The results indicate that living near a FEMA park is associated with less negative perceptions, while actually seeing trailer park residents is associated with more negative perceptions and a greater odds of avoidance, particularly changing driving routes. Whites are particularly concerned about crime associated with the parks, but interracial trust reduces negative perceptions of the parks and the likelihood of avoidance. Those who are likely to end up in a FEMA park if they were in the same situation are more friendly toward the parks and less likely to use avoidance techniques,The data used in this article were collected under support from grant number SES-0554572 to the three authors from the National Science Foundation. The findings reported here do not represent the views, opinions, or policies of the National Science Foundation. A draft of this article was presented at the annual meeting of the Mid-South Sociological Association, October 2006 in Lafayette, LA. We appreciate helpful comments from several anonymous reviewers on a prior draft of this article.Address and negative perceptions themselves are strong predictors of avoidance behaviors. We conclude with a discussion of directions for future research.
