Proposed Time Line

Agency FY2014 FY2015 FY2016 FY2017 FY2018

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

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%).
