Joplin anniversary events start at hospital Joplin anniversary events start at hospital - Weather Joplin anniversary starts with hospital service Staff, survivors gather at hospital that treated hundreds JOPLIN, Mo. - A day of reflection to mark the first anniversary of the twister that killed 161 people and destroyed a third of this city started with a sunrise service outside a hospital that survived. The May 22, 2011, twister -- the nation's deadliest in six decades -- also injured hundreds more and destroyed thousands of buildings, including the city's only public high school. Groundbreaking ceremonies are scheduled at three sites for replacement buildings, including Joplin High School's future home. Gov. Jay Nixon, who joined President Barack Obama on Monday night as a Joplin High School graduation speaker, attended the sunrise service and "journey of healing" at Freeman Hospital honoring the city's medical workers and volunteers who treated hundreds of tornado patients. The hospital has seen a surge in use after the tornado destroyed St. John's Regional Medical Center, which was just eight blocks away. the medical center has since occupied a succession of temporary facilities but is being rebuilt at a new location - and renamed as Mercy Hospital Joplin. A 4-mile unity walk through some of the city's hardest hit neighborhoods begins at 2 p.m. in neighboring Duquesne, where more than one-fourth of the community's 750 homes were destroyed and nine people died. The Joplin portion of the walk begins past a Wal-Mart where 200 people survived the storm by huddling together in employee break rooms, bathrooms and other designated safe zones. Three people, though, were killed inside that store. The walk will conclude with a moment of silence at Cunningham Park at 5:41 p.m., the precise time when the EF-5 tornado packing 200 mph winds hit Joplin. The city park, which is across the street from the hulking remains of the St. John's hospital, has since been rebuilt. While many of Tuesday's events will reflect upon the past year, community leaders are also looking ahead toward what is bound to be a long recovery effort. In January, elected officials and other members of a 45-person recovery committee endorsed a long-term recovery plan that calls for the creation of four new business districts that would allow residents to live and shop nearby and a unified approach to rebuilding that ensures new construction meets certain design standards. In March, the city hired Wallace Bajjali Development Partners, of Sugar Land, Texas, as its "master developer" to oversee the rebuilding plan. The day's events also attracted some of the 130,000 volunteers who descended on southwest Missouri from across the country to help out. That group includes a contingent of bicyclists who left New York City's Central Park nearly three weeks ago on a Cycle for Joplin fundraising ride organized by a group of former Joplin residents known as the Joplin Expats.
