GLENVILLE ? Glenville planning officials received their first look at a proposed mixed-use project from the developer of Socha Plaza, whose architect said he hopes it "raises the bar" for the town. Owner William Socha is planning a 60,000-square-foot commercial and residential building on a nearly 10-acre property between Socha Plaza and Socha Plaza South on the west side of Route 50. The three-story, L-shaped structure would have retail and restaurants on the first floor, office space on the second and about 17 apartments on the third floor. Socha told the Planning and Zoning Commission Monday that his existing commercial property is 100 percent full and his residential units are 98 percent full. With favorable interest rates and the other commercial activity in town, such as the new Target under construction, now is the time to develop this property, which he purchased 20 years ago, he said. "It's great to be back and finally be finishing off this site."
