The original purpose of this study was to determine the feasibility of assessing physical activity in the playgrounds before and after renovation and to evaluate which playground enhancements impact children’s physical activity. However, due to the impact of Hurricane Katrina, the scope of this project had to be changed. The revised objectives of the study were to (1) describe the development of an instrument to assess park conditions following a hurricane and (2) document the conditions of New Orleans' parks 3 and 6 months after Hurricane Katrina. A Post-Hurricane Assessment (PHA) instrument was developed and implemented in 54 parks 3 and 6 months after the hurricane.
