LOS ANGELES -- Los Angeles city Councilwoman Jan Perry today reached out to potential donors to help the city defray at least some of the costs to cover sanitation other services for the massive Michael Jackson memorial downtown Tuesday.

It's not yet known how much the event will cost the city, but the recent Lakers' championship victory celebration downtown incurred $2 million worth of city services -- mostly for police, traffic control and sanitation -- a figure covered by wealthy donors.

Some news outlets have speculated that crowds surrounding the barricades outside the Staples Center memorial could dwarf the tens of thousands who came to celebrate the Lakers win.

Perry says the cash-strapped city will dip into a special fund that sets aside money for unforeseen events, but she welcomed donors to step forward. She says the Jackson family has not come forward.
