An announcement Wednesday morning following a Downtown Development Authority meeting is expected to lay out the plans for a development expected to cost more than $50 million in the area formerly known as Harmonie Park in Detroit.

Now known as the Paradise Valley Cultural and Entertainment District, multiple groups are expected to be awarded preliminary development agreements for five buildings and two surface parking lots in the small downtown enclave.

A group led by Dennis Archer Jr., president of Archer Corporate Services and son of former Detroit Mayor Dennis Archer, is expected to be selected to redevelop the buildings at 1407 and 1427 Randolph St.

Archer Jr. said Tuesday morning that he responded to the Detroit Economic Growth Corp.'s request for proposals last fall with what he called a "phenomenal package" for the two properties, including perhaps a hospitality component. However, he said he had not been notified that his development group was selected to proceed with a redevelopment project.

A development group led by Hiram Jackson, publisher of the Michigan Chronicle and co-owner of its parent company, Detroit-based Real Times Media Inc., is expected to be awarded a development agreement for two surface parking lots at 1455 Centre St. and 1468 Randolph St., according to sources.

An email sent to Jackson seeking comment was not immediately returned.

Rainy Hamilton, president and co-owner of the architecture firm Hamilton Anderson Associates, is expected to be awarded a development agreement for the building his company occupies at 1435 Centre St., sources said. Attempts to reach Hamilton for comment were not immediately successful.

Ismail Houmani, who owns the cigar bar La Casa de la Habana, is expected to be awarded a development agreement for his building at 1502 Randolph St., according to a source.

Who receives the development agreement for the final building included in the RFP, the Harmonie Club Building at 311 E. Grand River Ave., is not yet known.

That property and its primary occupant, The Arts League of Michigan, which operates as the Carr Center, has generated attention in the last couple of months as the Carr Center is expected to leave the building following an unsuccessful attempt to purchase it in the RFP process.

Wednesday's announcement of the redevelopment plans is expected to take place in Paradise Valley after the DDA meeting, which begins at 10 a.m., according to a DEGC spokesman.

The DDA began purchasing property and completing infrastructure improvements in the area beginning in 2004, spending about $14.4 million.

The five buildings in the RFP total about 94,000 square feet.

Paradise Valley's boundaries generally follow those of Beatrice Buck Park: Centre and Randolph streets and Grand River Avenue.

In addition to its thriving jazz scene, the historic 66-square-block former Paradise Valley neighborhood — which was roughly bounded by Adams, Brush, Alexandrine and Hastings streets — was known as a mecca of African-American business ownership and had businesses ranging from drugstores to beauty salons, bowling alleys to theaters, nightclubs and miniature golf courses. The area was bulldozed in the late 1950s and early 1960s to clear land for the construction of I-75.
