A lengthy Sturgeon Bay Zoning Board of Appeals meeting Tuesday afternoon ended with the approval of two variance requests from Fincantieri Bay Shipbuilding with conditions attached.  After much discussion, the granted variances included conditions that require Bayship to submit a plan and schedule for Third Avenue improvements within six months to the City of Sturgeon Bay that addresses landscaping, parking enhancements, the appearance of buildings and follow storm-water management set down by the DNR.  The variance is for an existing building at the 273 N. 1st Avenue location and a new fabrication hall at 341 N. Third Avenue projected to be 110 feet high.  The current ordinance is for buildings not to exceed 45 feet.  Vice-President and General Manager Todd Thayse shared the shipyard’s upgrade plan associated with a U.S. Navy Frigate contract that would be a $30 million investment for the shipyard with a thirty-minute presentation.  The second ordinance also included a condition that must keep the building within three feet of its planned site with a 75-foot setback.  Chair Bill Murrock oversaw public hearing that went for over ninety-minutes with several people speaking in favor with written correspondences supporting the variance for the shipyard.  Several opponents then shared several concerns including shipyard noise, air and water quality issues, and skyline impact.
