I very much like the idea; however, @lpickup is the mastermind of the programming, so he will have to weigh in. Currently, there is no database field to tag a site as NEVI funded. At a minimum, we'd have to go back and add that to the planned site that are already entered (mostly in Ohio, Pennsylvania, Colorado, and Utah).
Just thinking out loud, it does seem like it would be tough to track this with only second hand information (we have good data for some, but not all states). I wonder if the government will come out with their own tracker?
