Dominion Energy is more entwined in the $1.5 billion Coliseum replacement and Downtown redevelopment proposal than previously disclosed.

The energy giant, led by Thomas F. Farrell II who also is spearheading the Coliseum replacement plan through the Navy Hill District Corp., has agreed to pay $20 million over two decades for the naming rights to the proposed $235 million, 17,500-seat arena.

Under the plan, Navy Hill would build the new Coliseum and Richmond taxpayers, including his company, would pay for it.

The discovery of Dominion’s enhanced role emerged as a new poll conducted Jan. 4 through 7 by the American Research Group found that 60 percent of residents in the city’s 3rd District, which is represented by City Council Vice President Chris A. Hilbert, oppose the Coliseum proposal.

The results of the poll of 300 residents mirror those from a previous ARG poll of 5th District residents that found a similar level of opposition. New Councilwoman Stephanie Lynch represents the 5th District.

The discovery came as City Council began public hearings on the findings of its nine-member Navy Hill Development Advisory Commission. By a 5-2 vote with two abstentions, the commission recommended in late December a rejection of taxpayer involvement in the Coliseum replacement plan, finding the proposal would not be “a sound and reasonable public investment.”

The public hearings are among the steps City Council is taking as it moves toward a vote in late February on the massive plan for a new arena and private development near City Hall. Mayor Levar M. Stoney is pressing the council to approve Mr. Farrell’s plan.

The plan also calls for bringing in more than 2,000 apartments, a 527-room hotel, office space, a GRTC transfer station and restaurants and retail to transform eight blocks of largely city-owned property located north of Broad Street between the Coliseum and City Hall, as well as two blocks of city-owned land south of Broad Street.

The council also will hold a public hearing before the vote on the proposal that Council President Cynthia I. Newbille has targeted for Monday, Feb. 24. The council is awaiting a separate consultant’s report, with a preliminary finding due on Friday, Jan. 31, and a final report expected by Monday, Feb. 10.

Based on council views, the mayor still appears to lack the seven votes needed to move the project forward, though he told the Free Press he remains “optimistic.”

The disclosure of Dominion’s heightened role resulted from political writer Jeff Thomas using government public disclosure laws to obtain documents from the nonprofit Navy Hill District Corp. that Mr. Farrell and other prominent individuals created to handle the giant development.

Mr. Thomas, who last year requested that the Internal Rev- enue Service revoke Navy Hill’s nonprofit status for violation of regulations governing such tax-exempt entities, secured the documents by seeking from Navy Hill a copy of its nonprofit application and related documents, including responses to IRS questions before the nonprofit status was approved last spring. “The documents reveal (that) the naming rights were sold to Dominion for $1 million a year for 20 years,” Mr. Thomas noted in an email.
