It holds a grand opening Sept. 14 through Sept. 16.

Mosaic, developed by Edens, includes a number of retailers and restaurants. The 350,000 square feet of retail also includes a movie theater and 72,000 square feet of offices.

MOM’s Organic Market will open its 10th area store in Waldorf later this year.
