This study examines the premise that the infrastructure and buildings surrounding a community parks has a direct affect on how many people participate and visit the park. This study’s has two main agendas: (1) improve our understanding of the link between the built environment and participation within parks, and (2) suggest improvements to better site parks for community participation within policy and planning. The comparative research design uses mapping and spatial analysis of parks within two different communities in San Diego: one in an more urban environment and the other in a more residential suburban community. The parks will be evaluated through direct observation, meetings with County parks officials and academic research. The study found differences in infrastructure as well as community participation within the parks studied. But it is not necessarily the case that these differences make one park better than the other. The parks need further analysis of content within the park to fully understand the relationship between park visitors and the park itself.
