This project is to replace the current low water crossing near Old Fredericksburg Road and Lost Creek Gap Rd. with a structure capable of passing the 1-percent-annual-chance (100 year) storm without overtopping the road. There is a subdivision upstream of the low water crossing which contains a large detention pond intended to reduce the flow of storm water across Old Fredericksburg Road. However, there is no structure currently under this road. With the new subdivision and other development in this area, the removal of the low water crossing is important for area residents.
