Wegmans is negotiating a deal to open a store as part of the Scotts Run Station South development in Tysons Corner, according to sources close to the discussions.

According to the sources, who were not authorized by the parties to speak publicly, the store would be on Colshire Drive, just off of Route 123, a short walk from the McLean Metro station that is currently under construction.

Wegmans, based in Rochester, N.Y., has traditionally built stores of well over 100,000 square feet with large surface parking lots. But in Tysons — where it would have the opportunity to serve McLean — the grocer is considering a smaller, urban format of 80,000 square feet.

In the spring of 2014 the chain plans to open an 82,000-square-foot store in Chestnut Hill, Mass., a Boston suburb, that will be the first of its kind. That store will include a 11,000-square-foot wine shop on the second floor.

The Tysons store would be part of a massive mixed-use project that Cityline Partners is preparing for what is now a spread of parking lots and older office buildings along Route 123, one of the largest development projects in Tysons Corner.

In April, Cityline received approval from Fairfax County to build 6.7 million square feet at Scotts Run Station South, although it would likely have to seek a zoning change to accommodate Wegmans.

In Tysons, according to the sources, Cityline would ink a deal with Roadside Development, of the District, for Roadside to develop the Wegmans with apartments or condominiums on top. Cityline has already lined up separate deals with three other residential developers, Home Properties, JLB Partners and Hanover Co., that would lead to hundreds of new apartments in the project.

Thomas D. Fleury, executive vice president of CityLine, did not respond to requests for comment. Richard Lake of Roadside Development declined comment.

Wegmans already has stores in Columbia, Fairfax, Sterling, Lanham and in Woodbridge, as part of another Roadside project. A Wegmans spokeswoman declined to comment on the Tysons discussions but reiterated interest the company has expressed since 2011 in opening a store at the former Walter Reed army hospital.

At Walter Reed, Wegmans is working with Roadside, which is one of a number of companies the D.C. government may consider as a partner.
