HOUSTON (AP) - A team of consultants is recommending that the Astrodome be turned into a multi-purpose facility that could host sporting events and massive exhibitions, while also preserving the iconic structure's outer shell.

The $270 million option was one of four considered by consultants led by Dallas-based CSL. The other options included leaving the vacant stadium alone, demolishing it and building an outdoor plaza, or building a massive "renaissance" complex.

In a presentation to Harris County's sports and convention wing, the consultants said the multipurpose option could turn Houston into a popular destination for special events and national trade shows.

The recommendation now goes to the Harris County commissioners, who can take up the matter at their next capital projects meeting in June.
