Two members of the D.C. City Council proposed yesterday that the federal government give the city more than twice as much money as it already does as compensation for revenues the city loses because it is the nation's capital.

Council members Marion Barry (D at large) and Polly Shackleton (D three), introduced a resolution urging a $600 million federal payment in 1979. The most the city could receive as a federal payment in the coming fiscal year which begins in October, is $300 million.

The Council members also asked that in subsequent years, the federal payment be fixed through a formula that would make it equal to 50 per cent of the city's opearating budget, which is currently $1.2 billion.

The federal payment is supposed to reimburse the city for money it loses because federal land and buildings are exempted from city property taxes, and some city operating costs, such as police services, are increased because the city is the nation's capital.

Barry and Shackleton asserted that the current amount is only partial compensation for what the city is actually losing through the federal presence. In addition, they said, a fixed federal payment would make budget planning more sound for city officials.

for 42 years, beginning in 1878, the federal payment was equal to 50 per cent of the budget, they said. Now it has dwindled down to a 28 per cent level, according to Barry and Shackleton.
