135.74148+90137.24pipe/fencepla smo18Pipe Open - pipe has been dug out, will need to return and remove more slide. Slide material is up against hillside and will be washed into pipe with heavy rainfall.
Has two gasline posts in the drainage ditch.
River side of hill appears to have a bench about 40 feet down, may be okay to dump fill.
7/4 dig to about 1 foot below trail elevation on west side.
7/6 dug to about two feet below trail elevation on east side, found the pipe.
7/11 dug one foot below bottom of pipe to allow for from steep sides
7/16 cleared swale on side of gasline pilings away from pipe
This is one of most significant basins that needs to be dug out between pipe and hillside. High Priority Drainage Area.
