Takoma Park's mayor and City Council last week adopted a resolution accusing the Soviet Union of "barbarism" and supporting President Reagan's response following the missile assault that downed a South Korean airliner Aug. 31.

"This atrocity has shocked the world for its callous disregard for human life and the accepted norms for civilized society," the council members said in the resolution, which was sent to Reagan, the Maryland General Assembly and the Soviet ambassador to the United States.

In local action, the council approved requests for $780,000 in community development block grant money, most of it aimed at fueling the revitalization of the city's commercial district.

With the long anticipated reconstruction of "streetscapes," parks, facades and lighting under way in the older part of the city just above the District line, the council approved a $175,000 application to bring similar developments to "Takoma Junction," the intersection of Carroll and Ethan Allen avenues, assistant city administrator Richard A. Schnuer said.

Officials plan to get architectural and engineering work going by next fall, Schnuer said, and hope to link the commercial renovation of both areas on Carroll Avenue.

The council also requested $100,000 for the "Takoma Park Equity Demonstration Program" of no-interest loans for low- and moderate-income renters in the "Between the Creeks" neighborhoods along Flower Avenue who want to form cooperatives and buy and repair their apartment buildings, Schnuer said.

Another program would set aside a fund of $100,000 in rehabilitation loans and grants for low- and moderate-income homeowners. City officials also asked for $50,000 to buy houses that have been illegally converted into apartments, restore the buildings and sell them as single-family houses in what Schnuer called "a turnaround program."

Other project requests included $100,000 for street and sidewalk repairs in the Between the Creeks area and another $100,000 for similar public improvements elsewhere, $44,000 for parks and recreation, about $50,000 for staffing costs of the programs and $55,000 for economic development.

A county block grant committee will recommend projects to be funded, said Lou D'Ovidio, a City Council member and Takoma Park's block grant representative to the county. Community requests have amounted to $8 million, he said, about twice the money available. The council is expected to decide on the projects next spring.
