The two Robinson Terminal warehouses that played a big role in Alexandria’s waterfront controversy two years ago were sold Friday by the Washington Post Co. to separate developers for undisclosed prices.

The Post identified the buyer of the northern warehouse as CityInterests/Armada Hoffler and the buyer of the southern warehouse as EYG/JBG. The warehouses are within eight blocks of each other in Old Town Alexandria. The city assessed the two warehouses together at about $30 million.

A.J. Jackson of EYG confirmed the sale but would not say what the firm’s plans are for the 3.5-acre property at the foot of Duke Street. In a statement, the company said it was looking forward to “working closely with Alexandria . . . to redevelop this one-of-a-kind property in accordance with Alexandria’s recently adopted waterfront plan.”

Peter Farrell, a principal at CityInterests, said Friday evening that his company plans to build a luxury boutique hotel with residential and retail development.

Opponents of the waterfront plan had argued that the city was allowing too much development along the Potomac River. Proponents said it was time to address outdated and disjointed land use on the waterfront.
