Abstract

The assessment, remediation, and redevelopment of brownfields have numerous benefits to the natural and human environment. This study was conducted to model the extent of brownfield sites in Humboldt County, California. Several factors increase the difficulty of determining what should be included in a brownfield inventory: the large varied property involved, the private and changing nature of land tenure, and the varying quality of data. A geographic information system (GIS) inventory was established using information obtained from federal, state, and local information sources that detail contamination status, environmental concerns, and existing land use. Data gaps and inaccuracies were addressed through key informant interviews and site visits. From this data, a predictive GIS model was created. To test the efficacy of the model, field surveys were conducted in a subset of the study area. Field survey results and site assessment work were integrated into the model. The research suggests that as many as 9,425 hectares of property in Humboldt County meet the conceptual definition of a brownfield. The results of the study indicate that the GIS brownfield model is an important contribution to the implementation of ground surveys, planning, and incentive programs to facilitate site reuse in Humboldt County.
