Abstract

Green infrastructure plays an increasingly important role in managing stormwater and improving human connection to nature in urban areas. My objective was to examine resident awareness of green infrastructure (GI) projects near Johnson Creek restoration sites in the City of Portland, Oregon. Using a mail survey, residents reported their awareness of local water features undergoing restoration. Geographic Information Systems analysis was used to measure the distance, by both street network and Euclidian distance, from each respondent’s residence to the closest active green infrastructure water feature project. Linear regression was used to determine the relationships between the three dependent variables and 17 independent variables. Results suggested that respondents whose residence was a shorter distance to active restoration projects were more likely to have a greater environmental worldview score reflecting environmental dominance over human intervention and greater income. These findings suggested that residents living closer to green infrastructure projects may share characteristics that can help guide future green infrastructure planning and community outreach efforts to currently underinvested areas.
