Residents for Environmental Justice, successfully challenging proposed developments
throughout California for their impacts to greenhouse gas emissions, environmentally sensitive
habitat, air quality, fire risk and evacuation, and safety from explosive and volatile chemicals.
One of the cases Katie has worked on resulted in permanent preservation of 1,300 acres in
Proctor Valley, an area vital to the endangered California gnatcatcher and Quino checkerspot
butterfly. She continues to litigate to preserve San Diego’s incredible biodiverse habitat.
