Eager to find a home for a new team in New York, officials from Major League Soccer met officials from the Hudson River Park Trust on Thursday to discuss a potential stadium on Pier 40 on the West Side of Manhattan.

The meeting, which included about 30 politicians, park officials and other city representatives, was the first full discussion at the trust about the possibility of building a soccer stadium on the 14.5-acre pier at Houston Street, which now has several soccer fields and long-term parking.

Mark Abbott, the president of M.L.S., was asked about the size of a proposed stadium, how often it would be used and what facilities would be available for the public. He was also asked about crowd control, parking and who would run youth soccer programs, according to several people at the meeting.

Though M.L.S. has several designs, any stadium at Pier 40 would take up about nine acres, seat 20,000 to 25,000 fans and include youth soccer facilities. Trying to expand the size of the pier would probably be very problematic for environmental and political reasons.
