The St. Louis Economic Development Partnership has delayed until next week its recommendation for inclusion in a regional bid for Amazon’s $5 billion second headquarters.

“We’re not there yet,” the partnership’s CEO, Sheila Sweeney, said Tuesday of her agency’s review. “There’s a lot that goes into it. It’s extensive.”

More than 27 sites across the area have been submitted to the partnership. Sweeney had said last week that she wanted a decision on the area’s plan by Tuesday or Wednesday.

Sources say a joint proposal involving downtown St. Louis, the riverfront area just north of downtown and East St. Louis is the leading contender.

Sweeney and Jim Wild, executive director of the East-West Gateway Council of Governments, said Tuesday they expected the partnership’s recommendation to be submitted to Gateway’s board next week and that an endorsement would be sought then.

The 24-member board, which makes regional decisions on transportation spending, is made up of the top elected officials in St. Louis and the larger area counties, plus some other members.
