Western Development Corp., a firm that also is planning a commercial complex in Georgetown and has started a new shopping center in Great Falls, is currently putting together a 106-acre industrial park at the Dale City interchange and Rte. I-395 in Prince William County.

Herbert Miller, president of Western Development, said that the center will include land of warehouses, assembly and distribbution facilities plus a 34-acre, 80,000-square-foot commercial-retail center that will be started later. He added that other plans are under way to improve the Dale City interchange and also to develop a major shopping mall nearby within a few years.

In its first phase, the Northern Virginia Industrial Center is providing firms with industrial sites starting at $.74 a square foot. Already parcels have been sold to Chesapeake Supply Co. and Bond Office Services, he added. Both plan to build and relocate from other sites in the area.

Other buildings will be developed for leasing on the site. Miller said sewer and water services are available and that clearing of the site will begin in May. Both large and small use tenants will be accommodated.

Miller pointed out that the site is near the communities of Dale City, Lake Ridge and MarumscoHills, which already have more than 60,000 residents.
