Villaraigosa will join executives from L.A.’s largest public pension funds L.A. City Employees Retirement System; L.A. County Employee Retirement Association; L.A. Department of Fire and Police Pensions – to announce the commitment of $65 million to the Genesis Workforce Housing Fund II, a private equity real estate fund managed by Phoenix Realty Group.

The press conference will be held at Puerta del Sol, a workforce housing community that is represents the type of development to be funded with the pension investments.
