May 1: MatriCal Inc., a Spokane company that designs and manufactures products used for scientific research, says its planned move to the Riverwalk Plaza here will allow it to keep its operations and corporate offices consolidated in one location. Margo Buckles, an administrator for MatriCal, says the new location, at 1007 E. Trent, is ideal, because at 17,000 square feet it’s bigger than other locations the company considered elsewhere in the University District, where it wants to stay. Currently, MatriCal is located in a 10,000-square-foot space in the Sirti Building, at 665 N. Riverpoint Blvd.
