February 17: Public Presentation to Report Results of the Brownfields Assessment in Nevada County

The public was invited to an informational presentation about the Gold Country Coalition EPA Brownfields Assessment Grant. The Sierra Fund hosted a virtual community meeting with the City of Grass Valley in order to disseminate the findings of the work completed. The presentation reported the results of the assessments done on properties impacted by historic mining activities for the presence of contamination, and to prepare plans to address sites where contamination was identified.  Assessment was conducted on eleven properties in Nevada County totaling 386 acres; all of these sites were close to population centers.  Seven cleanup plans were prepared for 229 acres of property with mining contamination.  

A video recording of the meeting is available here.

A Brownfields site is a property with the real or perceived presence of a hazardous substance, pollutant or contaminant which can complicate development or reuse. Cleaning up and developing these Brownfields properties can facilitate job growth, take development pressures off undeveloped land; and improve and protect the environment and public health. Presentations were followed by audience Q&A.
