The landslide at Shoal Creek could be a ticking time bomb for the city and residents living up top.
Plastic-like clay between two layers of limestone that got very wet after being very dry is what caused the Shoal Creek slope failure landslide. That's according to Watershed Protection Managing Engineer Mike Kelly. The landslide is blocking Shoal Creek which could be a problem for drivers next time it rains hard.
Engineers will start soil boring tests next week to determine how bad it is and what can be done next.
