	Type 2 aluminized steel sheet piling at John Paul Jones Park on the southern shore of Lake Ray Hubbard. This project was designed for the City of Garland Parks Department and is nearing completion. This lakeside park had been heavily impacted by extensive erosion and several areas were closed to public use. With the construction of the sheet piling and earthwork improvements, the park may be reopened to the public and will be protected for many years to come. A total of over 3,200 linear feet of sheet piling was constructed with this project including three fishing piers and one boat ramp.
