A summary of selected City Hall actions this week affecting central Los Angeles. : CITY COUNCIL

RETAINING WALL--Approved the use of $140,000 to repair a retaining wall at 2400 Sunset Blvd. that was damaged during recent rains. The wall, at the bottom of a steep slope at Sunset and Coronado Terrace, is considered a potential hazard. Reconstruction is scheduled to begin next month.

* HAZARDOUS BUILDING--Approved the use of $15,000 to immediately secure a three-story apartment building at 2017 N. Argyle Ave., which one Fire Department official termed a “tragedy waiting to happen.” The dilapidated building will be fenced off and boarded up so no one can enter.

* REWARD OFFERED--Approved a $25,000 reward for information leading to the arrest and conviction of the person or persons responsible for the murder of 35-year-old Jose Ornelas, who was found strangled near 7th Street and Broadway on the morning of Dec. 9, 1994. The mentally handicapped Ornelas, a resident of Oklahoma, had been visiting his family in Panorama City when he strayed away. Anyone with information about the case should contact Los Angeles Police Detective Emmett Bada at (213) 485-2671.

* SOUL TRAIN AWARDS--Approved the closure of 32nd Street between Hoover and Figueroa streets, and Royal Street between 32nd and Jefferson streets, on March 13 between 11 a.m. and 10 p.m. for the ninth annual Soul Train Music Awards at the Shrine Auditorium.

HOW THEY VOTED

How South-Central and Eastside City Council representatives voted on selected issues.

* RHINO BULLET BAN--Approved a motion supporting a proposed federal ban on so-called Black Rhino bullets and similar ammunition said to be capable of penetrating armored vests. The bullet has not yet been tested by federal officials and some authorities doubt its ability to actually pierce body armor. Nevertheless, the move to ban the ammunition was endorsed wholeheartedly by council members. “This has nothing to do with the right to bear arms,” Councilman Richard Alatorre said. “This bullet doesn’t serve any useful purpose.” Passed 11-0. Voting yes: Alatorre, Jackie Goldberg, Mike Hernandez, Nate Holden, Rita Walters. Absent: Mark Ridley-Thomas, Rudy Svorinich Jr.
