The following were among actions taken at Tuesday's meeting of the Montgomery County Council. For more information, call 251-7900.

DAY CARE CENTERS -- In a move aimed at curbing the chronic shortage of day care centers in the county, the council introduced an amendment to zoning regulations that would allow developers to add day care centers to the list of negotiable ammenities they sometimes propose in commercial developments in exchange for county permission to build projects larger than allowed by zoning regulations.

More than 47,000 children in Montgomery County need day care, but only about a third of them are receiving such care from registered and monitored providers, according to county officials.

ART IN PUBLIC PLACES -- As part of Montgomery County's Art in Public Places program, the council approved new art projects for public buildings in the county.

Among the projects the council approved were a mural for the Olney Library, $10,000; a bronze hanging sculpture for the Davis Library in Bethesda, $5,000; two ceramic murals and an oil painting for the Potomac Community Center, $17,000, and murals and a sculpture at New Hampshire Estates Elementary School in Silver Spring, $45,000. New Hampshire Estates is closed for renovation, but will reopen next fall.

According to the public art bill passed by the council in 1983, at least 1 percent of the estimated construction cost of certain capital projects must be used to purchase works of art for public buildings in the county.
