Codornices Creek, an ecological corridor located in the northern part of Berkeley, California, is among the most visible, publicly accessible, creeks in the East Bay, flowing through socioeconomically diverse neighborhoods. The current study examines the comparative influence of the following factors on the area residents' sense of community and perception of area ecology: individual-level socioeconomic conditions, the involvement of local area residents in creek restoration activities, and the existing creekrelated land use regulations. Based on the data collected through field measurements and a survey of the creek area residents, the study finds the respondents' exposure to the City of Berkeley's Creek Ordinance, a key land use regulation in the Codornices Creek area, to be among the most important factors affecting their perception of the creek's role in stormwater management, while the comparative impact of socioeconomic conditions appears to be less important. In contrast, exposure to the ordinance is found to have no significant impact on the respondents' sense of community or overall perception of area biodiversity. Surprisingly, not one of the three outcomes of interest-the sense of community, perception of area biodiversity, or awareness of the creek's role in stormwater management-appear to be strongly affected by the respondents' involvement in creek-focused restoration activities.
