There has been work this week on the 4 Mile Run Trail just east of George Mason before where the power lines cross. Over the past couple months waters has been seeping over this section and was forming ice. Monday there was work being done with some type of drainage pipe on the south edge of the trail. This morning a truck was parked across the trail and workers were picking up orange cones. The drainage pipe is now buried and there is a layer of gravel over it (French drain?). I’m not sure what the issue was, but it will be interesting to see if this solves the water seepage issue. If it works, maybe the NPS can be convinced to do something similar with the Mt Vernon Trail section just south of Memorial Bridge that has been seeping water and was bad ice again this morning.
