CHESAPEAKE, Va. — Dollar Tree announced it is planning to consolidate store support centers here as part of its continuing integration of Family Dollar’s organization and support functions.

The company on Tuesday said it plans to close the Matthews, N.C., headquarters of Family Dollar after the consolidation is completed in the fall of 2019, but that a distribution center in Matthews will remain open to serve Family Dollar stores.

Dollar Tree said about 700 employees were given offers to relocate to the consolidated headquarters here. Jobs of about 200 other employees are being eliminated. Dollar Tree said it would provide job transition benefits and outplacement services to the affected workers.

“By bringing our teams together into one location, we will further improve our ability to support our stores more effectively through enhanced collaboration, communication and teamwork,” Gary Philbin, Dollar Tree’s chief executive officer, said in a statement. “The completion of our expanded headquarters in Virginia will facilitate the most important phase of the integration, and we are excited about the opportunities ahead for the Dollar Tree and Family Dollar banners.”

The news comes three years after Dollar Tree acquired Family Dollar, a fixture in the economic fabric of Charlotte, N.C., since shortly after the first Family Dollar store opened there, in 1959. The founding Levine family expanded the dollar store business into an empire with more than 8,000 stores nationwide at the start of 2014, the year the company became the prize in a bidding war between rivals Dollar Tree and Dollar General.

Family Dollar agreed to be acquired for about $9.1 billion by Dollar Tree in July 2015.
