To summarize: 2015 actual budget, $381,108;  2016 revised budget, $441,319;  and 2017 proposed budget, $434,456.  In each case, that doesn't include well over $100K in interagency charges, and all but about $40K or so is paid in salaries and benefits.  Also in each case, these budgets including interagency charges are funded by permit and license fees.  As I stated elsewhere on this page, some TIs have overspent to push their particular agendas regardless of the understanding that they're supposed to operate on a self-support basis.
