Turning the Tide in Tulsa

Army Corps uses river analysis technology
to mitigate flood damage

Memorial Day 1984 was a muggy Sunday in Tulsa, Okalahoma. It also proved to be one of the darkest hours in the city’s history. While many in the rest of the country enjoyed barbecued ribs and chicken wings, people in Tulsa watched nearly 7,000 of their homes and other buildings washed away by a devastating flood. It killed 14, injured 288 and cost the city $180 million.

Flood is a recurring theme in Tulsa’s history, going all the way back to 1908. On the first anniversary of Oklahoma’s statehood, the Arkansas River overflowed, costing Tulsa $250,000. In 1970, Mingo and Joe Creeks swept away property worth $163,000. In 1974, Bird Creek unleashed its fury twice, in April and May. Later on, in June, its destructive example was followed by Joe, Fry, Haikey and Mingo creeks. In September, Mingo Creek flooded once more to close out the year. In 1976, yet another flood destroyed 3,000 homes and left the city with a $40-million damage bill.

After all of this destruction, why is the NFIP (National Flood Insurance Program), a FEMA (Federal Emergency Management Agency) offshoot, offering Tulsa residents federally backed flood insurance at a 40% reduction in premiums? Russell Wyckoff, a hydraulic engineer for the U.S. Army Corps of Engineers, Tulsa District, has an explanation. Read More >>

One program that seeks to bring together the CAD and GIS worlds is Autodesk Map 3D 2007. With this latest release, Autodesk makes it clear that it's serious about integrating geospatial data into CAD. Read More >>
