11. The estimated project cost is $900,000 over five fiscal years
(FY 2014-2018). All project costs would be shared by the
USGS (40%) and the project partners (60%).

USGS $64,000 $80,000 $88,000 $88,000 $40,000
Project Partners $96,000 $120,000 $112,000 $112,000 $60,000
Total $160,000 $200,000 $220,000 $220,000 $100,000
