MGN Online LOS ANGELES (AP) – A proposal that would authorize the mayor of Los Angeles to execute contracts related to the city’s bid for the 2024 Olympics has advanced amid questions about potential runaway costs. A City Council committee Friday referred the plan to the full council, which is not expected to vote until next week. Mayor Eric Garcetti and organizers behind the Los Angeles bid project the Olympics would be profitable. Among concerns, however, is a warning by city analysts that construction costs for athlete housing may be significantly underestimated. The U.S. Olympic Committee last month cut ties with Boston, which was initially selected as the U.S. contender. With Los Angeles the likely stand-in, the USOC faces a Sept. 15 deadline to enter a bid. THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP’s earlier story is below. City analysts warned that construction costs for athlete housing in Los Angeles’ 2024 Olympic bid may be significantly underestimated. The cost of acquiring land and building an Olympic Village for athletes near downtown Los Angeles “may significantly exceed” the projected $1 billion cost, according to a preliminary report released Thursday from city Chief Administrative Officer Miguel Santana and Chief Legislative Analyst Sharon Tso. The proposed site is a container-handling rail yard owned by Union Pacific Corp. The railroad said in an October letter to the mayor that it has no plans to close or relocate the facility and is planning a major modernization of the site, but would be open to the possibility of a sale or exchange agreement involving a “suitable replacement facility with all the necessary permits and approvals.” The report by the city officials says more study is needed. A City Council committee was scheduled to discuss the issues in the report on Friday as it considers giving Mayor Eric Garcetti authority to execute agreements linked to the bid, a steppingstone toward entering the international competition for the games. A vote on the matter could happen as early as Friday, but is expected to come next week. Garcetti said Thursday in a meeting with the editorial board of the Los Angeles Daily News that the games would be a money-maker for the city. “I think it’s much, much more probable that we’ll have a lot of revenue sources that come from this than worrying about the loss,” Garcetti said.
