The construction of the levee continued until it reached the elevation of the 1,000-year rain event. The clay core is 15 feet wide at the top and is covered with a load distributing geotextile fabric and an interlocking rock layer. The upstream armoring stone consists of angular limestone material ranging in size from 12” up to 36”. The material is free draining to allow for the rapid draining of the water after flood events to limit infiltration into the clay core.

construction company, they couldn’t design it themselves. They could’ve called many engineering firms to help, but they called us. That is very gratifying. Ken: The teamwork was amazing. This is the first time I’ve collaborated with Ted and Diane and the transportation group, and they jumped in and helped wherever needed. It just feels good to be a part of a group like that. Working with three different surveyors to gather and organize information so we could produce an accurate design didn’t leave much room for error, but we worked together and made it happen.

Diane Regensburg: It was also very rewarding to know that we exceeded the owner’s expectations by designing a project that addressed all the site constraints and allowed for construction of the new levee utilizing resources readily available to the owner. Our ability to thread a design solution through the site that used readily available clay and shot rock was a bonus that they did not expect. Most of all, being able to solve a problem caused by the Nashville flood was extremely rewarding. I had personal friends and colleagues who were greatly devastated by the

flood, and I spent many hours helping them recover. Being able to also use my engineering skills to address this problem was professionally fulfilling. I’m very proud of what we accomplished.
