(RECAP: As interested developers prepare their proposals, the site of a planned redevelopment along the Boulevard is becoming a cleaner slate. Demolition of 22 city-owned buildings and miscellaneous structures around The Diamond is wrapping up, on parts of the 60-acre site where the City of Richmond is planning a massive mixed-use development. The work is making way for a mixed-use development that would replace The Diamond with as many as 4,000 housing units, 500,000 square feet of retail and entertainment space, 375,000 square feet of office or flex space, and a hotel totaling as many as 250 rooms. Those numbers were listed in a market analysis as the highest and best use for the city-owned site, which includes The Diamond, the adjacent Arthur Ashe center and other city-controlled properties that make up the 60-acre site.)
