John Orona | Staff Writer While COVID-19 restrictions may have closed down many businesses and limited government services, it hasn’t stopped engineering. Tasked with overseeing developments, capital projects and generally maintaining and improving the city’s infrastructure, Grass Valley Assistant City Engineer Bjorn Jones said progress has continued. According to Jones, when the city first closed its offices to the public, the biggest challenge was the uncertainty. “There was a lot of unknowns with it. We didn’t know how much either our tax revenue was going to be affected or funding sources might be affected,” he said. “We did have to cut back immediately and kind of streamline our staffing and operations to meet with the unknown.”
