Nancy Davis thought the Big One had finally hit Kansas. One minute, the 75-year-old Lawrence resident was sitting on her deck in the northwest part of the city with three of her children. The next minute her deck had collapsed, throwing her and her surgically repaired hip off her chair and into the side of her home. “I thought it was an earthquake," Davis said. No, nothing that complex. Turns out it was just a poorly built deck, probably like hundreds of others in the city that were built before 2000. Davis' 12-year-old deck — attached to the back of her home at 3918 Tumbleweed Court — was inadequately secured to her home with simple nails. Today, city building inspectors require that decks be bolted to the side of a home. The builder of the Davis home, including the deck, was Tim Stultz, of Highland Construction.
