The Public Education seemed to be the best forum available for this topic so if it should be in a different one, let me know how to move it over.

Thanks Cathy for the reply. The grantor is Calfire, our state agency. It may interest other Firewise Communities in California to know that their Climate Investment Fire Prevention Program offers grants for hazard fuels reduction, based on the reduction of greenhouse gas emissions. One of the questions on the form was about how the project…
