Last year the Savannah-Chatham School Board paid $837,500 in education sales tax funds for an impressive new Spencer Elementary School building design that could help revitalize the low-income eastside neighborhood. What they got looked very much like an extension of the Blackshear Homes public housing projects. Wednesday the school board unanimously agreed to pay Cogdell & Mendrala Architects another $365,993 for a redesign. “It was designed and done before we had the opportunity to say what we wanted,” Superintendent Thomas Lockamy said to the frustrated school board members. The board complained that the architects they’ve hired to design all of their education sales tax funded schools ask for input on size, classroom space and building configuration, but don’t show them what the exterior will look like until after the pricey design work is done.
