In the late 1980s, an area of the Jurupa Valley in Riverside, California, began a transformation that would turn it from a community of sprawling dairy farms to hub for enormous warehouses.
David Danelski, then an investigative reporter for the Riverside-Press Enterprise, unraveled the details through public records on town planning and found one important document missing from projects approved by county officials for more than a decade: the environmental impact statement.
In Dillon Bergin's final guide on air pollution and public records, Danelski offers advice on how to find the documents local governments use to assess environmental consequences in town or city planning. Examples include environmental impact statements, air pollution control plans, and studies on the health impacts of air pollution. You can catch up on the full series here.
