PLEASANT HILL -- After 40 years, the Kmart in the DVC Plaza shopping center on Contra Costa Boulevard will close in mid-January, according to the company.

The company declined to renew its lease, said Chris Brathwaite, spokesman for Sears Holdings Corp., which owns the Kmart stores. Liquidation sales begin this weekend, he added

Brathwaite didn't know how many employees work at store. However, Pleasant Hill Economic Development Manger Kelly Calhoun said the company recently issued a Worker Adjustment and Retraining Notification, which California requires if a business plans to lay off more than 50 employees.

Built in the early 1970s, DVC Plaza includes 190,000 square feet of retail space, including the Kmart, McDonald's and small shops. Safeway closed its store in the shopping center in February and opened a new "lifestyle" grocery store in the renovated former Mervyn's building, also on Contra Costa Boulevard.

Four years ago, Pleasant Hill leaders made DVC Plaza eligible for redevelopment funds in an effort to revitalize the shopping center. But the recession hampered those plans and the end of redevelopment leaves the center's fate up in the air.
