The U.S. Army Corps of Engineers (Army Corps) Civil Works Program provides solutions to water resource issues. For example, the Army Corps uses National Oceanic and Atmospheric Administration (NOAA) storm climate data from the last 50 years and specific bathymetry to model storms along the entire west coast of Alaska and predict when an approaching storm will come onshore. The Army Corps Ecosystem and Watershed Program can be used on projects to restore the environment, provide structures that enhance water systems or remove structures that impede water systems. Army Corps also provides planning support with a 50-50 cost share for larger projects (typically $40,000 – $1milllion). The Floodplain Management and Silver Jackets Programs provide full funding for smaller projects (in the $10,000 – $200,000 range). The Army Corps can enter into sponsorship agreements with for-profit tribal corporations. The first $455,000 of Federal Cost Share is waived for Federally Recognized Tribes for all agreements, including planning studies for infrastructure projects carried out by the Army Corps.
