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

CITY COUNCIL

* 77TH STREET POLICE STATION--Approved the transfer of $1.1 million from the Police Department fund to the Department of General Services to cover the cost of temporary facilities to house the personnel of the 77th Street Police Station, which is to be replaced with a new building. The temporary offices, at 6100 S. St. Andrews Place, consist of several restored and reconfigured trailers. All personnel are expected to be out of the existing 77th Street facility by Tuesday. Construction of the new station will take at least three years.

* REWARD OFFERED--Approved a $25,000 reward for information leading to the arrest and conviction of the person or persons responsible for the Jan. 4 slaying of 80-year-old Sergio Hubasubo Gerolaga, whose body was found at the loading dock of a shoe store at 5485 N. Figueroa St. Police said Gerolaga was beaten to death and robbed. Anyone with information about the killing should contact Detectives Bob Lopez or Jose Carrillo at (213) 847-4261.

* DOGS ON THE BEACH--Authorized the city attorney to prepare an ordinance that would permit dogs that are trained to aid the deaf and other disabled people to be allowed on public beaches while they are used for such purposes. Currently, only guide dogs for the blind are allowed on public beaches.

* WILSHIRE BOULEVARD CENTENNIAL--Approved a resolution saluting the 100th anniversary of Wilshire Boulevard. It was in 1895 that financier Henry Gaylord Wilshire bought 35 acres of land and his name was attached to the road that dissected the property. Among the highlights this year along the boulevard will be the Wilshire Center Streetscape project, a multimillion-dollar beautification plan spearheaded by the Wilshire Chamber of Commerce.

* WILSHIRE LIGHTING IMPROVEMENTS--Authorized $700,000 for the refurbishment of the street lighting systems along Wilshire Boulevard between Hoover Street and Wilton Place. Installation of the street light wiring will coincide with repairs to existing sidewalks, which is part of the Wilshire Center Streetscape project.

HOW THEY VOTED

How South-Central and Eastside City Council representatives voted on selected issues. * LOST PETS--Authorized the Board of Animal Regulation Commissioners to negotiate a contract with MPO Videotronics for an automated service to help people recover lost dogs and cats. Under the system, people who have lost their dog or cat could call a 900 number and information about the pet would be entered into a computer. People finding pets could call an 800 number with information, and a computer match would be attempted. Exact cost of calling the 900 number has yet to be determined. Passed 10-0. Voting yes: Richard Alatorre, Mike Hernandez, Nate Holden, Mark Ridley-Thomas, Rita Walters.
