I can’t embed it, but DOT, HUD and USDA have created an excellent map of their grant programs. You can see relative amounts of money spent (“invested,” as they say) in each state, county, and then even down to the project level. 35 DC organizations, including supplemental nutrition programs and shelter and housing nonprofits recieved money from the various formula grant programs. The total allocation is $48.7M, determined by formula.

For the cartophobic and verbal learners, a list of all the USDA and HUD programs in DC is available here, beginning toward the end of the page.

USDOT’s map lacks the visual breakdown to individual projects and uses a totally different base map, but it still has projects lists in a pop-up window. DC’s distribution claims to be largely railroad investment, but a quick look reveals that the sum includes the $1B grant given to Amtrak, as though DC  is the only beneficiary.
