Over the following four years, a $12 million project to construct storm shelters for residents across the Oklahoma City metropolitan area was enacted. The goal was to create a safer community in a tornado-prone region. By May 2003, a total of 6,016 safe rooms were constructed. On May 9, 2003, the new initiative was put to the test as a tornado outbreak in the region spawned an F4 tornado, which took a path similar to that of the Bridge Creek–Moore tornado. Due to the higher standards for public safety, no one was killed by the 2003 tornado, a substantial improvement in just four years. On May 20, 2013, an EF5 tornado impacted some of the same areas affected by the 1999 storm, tracking through the heart of Moore. Throughout the city, 24 people were killed (along with one additional person who died as an indirect result of the tornado) and more than 230 were injured.
