Los Angeles' massive transit infrastructure investment promises benefits across the city and the region over the next decade and beyond, but it could also have unfortunate side effects if efforts aren't made to preserve affordable housing in transit-rich neighborhoods, according to a report commissioned by the City of Los Angeles Housing Department and written by Reconnecting America. The report was funded by the John D. and Catherine T. MacArthur Foundation, through the Awards for State & Local Housing Preservation Leaders of the Foundation's Window of Opportunity Initiative (WOI).
