The City Council this week gave its approval for a program to provide hot lunches for Greenbelt residents over 60 beginning March 10 at Green Ridge House, 22 Ridge Rd., Greenbelt.

Lunches, to be served between 11:30 a.m. and 1 p.m. Monday through Friday, will be free, although contributions will be accepted. Social activities will precede and follow lunch.

The lunch program is sponsored by the Prince George's County Department of Aging.

In other action, the council agreed to ask the county government to sell the city approximately 72 acres of Board of Education property at a "nominal cost." Originally slated for a three-school complex, the property was declared surplus in 1978.

The land is located between the Baltimore-Washington Parkway and Greenbelt Homes Inc. It abuts the city's athletic field complex, and would be used to expand the fields. The property lies in a drainage area that lacks water and sewer facilities which makes it uneconomical for housing or commercial development, city officials said.

The city also made a tentative commitment to issue revenue bonds to help finance the rehabilitation of Greenbelt Homes. The tentative commitment will help GHI secure a $6.4 million loan from the U.S. Department of Housing and Urban Development to begin the rehabilitation. According to the proposal submitted by GHI Deputy Director Kenneth J. Kopstein, several phases of work at GHI would require between $5.2 million and $16 million in revenue bonds.

Voters gave the council authority to issue the bonds at a referendum last fall. The council made no commitment, however, on the amount of bonding it will issue.

Finally, the city agreed to sell Metro flash cards and senior citizen passes at city offices. City treasurer Dennis E. Piendak said sale of the items would begin by March 15.
