LOS ANGELES -- For the wind-down of redevelopment to be anything short of a train wreck, successor agencies and oversight boards are going to need a keen understanding of real estate, public policy, economic development, and, of course, accounting. They're also going to need a lot of coffee and patience. But, according to Timothy McOsker, a member of the three-person board serving as successor agency for the Los Angeles Community Redevelopment Agency, the successful completion of the wind-down process is going to require something more subtle.
