SAN DIEGO -- San Diego Mayor Dick Murphy called a news conference Wednesday to announce his proposal to fill the $1.5 billion gap in the city's pension fund, 10News reported.

He outlined his proposal in a four-point program.

"There are several actions that I think need to be taken at this time and they are being outlined in this four-point program," Murphy said.

The mayor said his plan will bring fiscal responsibility to the pension fund. But his main political opponent said it was designed to hide the truth about the mayor's voting record.

The mayor introduced his plan as a package that has to work as one piece and not be taken apart.

"In concert, these proposals address problems of the past, the present and the future," Murphy said.

The plan includes the following four points:

Issuing $200 million in obligation bonds to bring the pension account to a 70 percent-funded level
A lawsuit settlement that calls for the city making full contributions to the fund over the next three fiscal years in 2006, 2007 and 2008
A 15-year amortization schedule insuring the pension fund is never underfunded again
Restructuring the retirement board, which currently has 13 members and nine of them are current or future city retirees

"My goals is to have this pension system operating in a financially responsible manor by the end of my second term as mayor," Murphy said.

However, Ron Roberts, the mayor's opponent in the upcoming election, said Murphy is assuming he is going to win in the future and is forgetting about his votes on the pension fund in the past.

"Dick Murphy doesn't want anyone to know that in 2002 he voted to underfund the pension fund all the way to 2009. Now, he's saying, 'Wait a minute. Maybe in 2008 we can come up with a long-term solution to address this issue,'" Roberts said.

Roberts also said he will come out with his own plan for fixing the pension fund in the coming weeks.

The City Council could take its first vote on one of Murphy's proposals as early as next week.
