Is anyone interested?

That’s the big question now that City Hall has issued its much-anticipated RFI, or request for interest from developers, for its so-called Diamond District — the 67 acres on Arthur Ashe Boulevard where The Diamond baseball stadium stands.

Leonard Sledge, the city’s director of economic development, issued the massive 163-page RFI on Tuesday.

The goal: To receive proposals for redevelopment of the property that is bounded by Arthur Ashe Boulevard to the west, Interstate 95 to the north, Hermitage Road to the east and the CSX railroad tracks to the south. The property includes about 60 acres of city-owned land and the 7-acre Sports Backers stadium that Virginia Commonwealth University owns.

Mayor Levar M. Stoney expects plenty of responses.

“Richmond offers location, diversity, authenticity and affordability,” he said. “Our city is the place to be, and the Dia- mond District is positioned to be a crown jewel in our thriving city.”

The RFI sets a Feb. 15 deadline for interested parties to respond with their vision for the property and information about their qualifications to take on a potential $300 million to $500 million project that the city regards as its next big thing to generate jobs, new homes, retail stores, office space and tax revenue for the city.

Respondents also must be willing to take on development of parks on the property and to tackle development of a replacement ballpark for the Richmond Flying Squirrels, the AA baseball affiliate of the San Francisco Giants that currently makes its home in the 37-year-old Diamond, according to the RFI.

Information on the new baseball stadium, which is to be built on the site of the Sports Backers combination soccer and track site, accounts for 47 pages of the RFI.

This is city’s second effort in the past decade to market the property on which it has spent between $14 million and $19 million to prepare for redevelopment.

If all goes well, the city would receive multiple responses. Following a review of no more than 30 days, the city expects to winnow the responses to a smaller number of teams that would receive a request to submit final offers, the RFI states.

Mr. Sledge’s office hopes to announce the winner of the competition by June and gain approval from City Council in July. One issue that remains unaddressed in the RFI is the ability of the city to transfer control of the Arthur Ashe Jr. Athletic Center, which is located on the acreage and owned by the city but managed by Richmond Public Schools.

The RFI states the Ashe Center, which occupies the key corner of Arthur Ashe Boulevard and Robin Hood Road, could simply be demolished, a position that Mr. Sledge previously shared with City Council. There is no mention in the RFI of a potential roadblock.

However, the Richmond School Board, armed with an opinion from its attorney, believes that it has authority over the building until it votes to make the building surplus property and return it to city control.

School Board Vice Chairman Jonathan Young, 4th District, has indicated that the school system could be induced to give up the building in exchange for a multimillion-dollar payout.

He said he believes a majority of the School Board would want something in return for Richmond Public Schools relinquishing the building.
