D.C. Mayor Vincent Gray is calling on the city to increase funding for a number of programs, including millions for affordable housing, without raising taxes.

In his proposed $10.1 billion budget for fiscal year 2014, Gray called Thursday for the elimination of a tax on income from out-of-state municipal bonds that is said to place a disproportionate burden on the elderly.

In keeping with past budgets, human services took up the largest share of the proposed city spending, making up 40 percent of the proposed budget. The human services budget would total more than $4 billion dollars under the plan. Just under $28 million would be directed to fill a void left by federal welfare funds. Another $5.9 million would go toward a further, largely anticipated, delay of proposed sanctions in the Temporary Assistance for Needy Families program.

Public education received the next largest share of the budget at 20 percent or just over $2 billion. The budget proposal direct hundreds of millions of dollars into modernizing D.C. school buildings.

Gray's budget proposal would allow libraries in the District to operate seven days a week and it sets aside money to revitalize D.C. libraries including Martin Luther King, Cleveland Park and Woodridge.

The budget also proposes establishing a $15 million "One City Fund" for competitive grants to be administered by the Community Foundation for the National Region.

The mayor wants to direct $50 million toward acquiring land and developing a parks in the growing NoMa neighborhood.
