possible dump site
Erosion on RR side of trail - need to make sure trench is open on hillside. Also may want to add dirt on RR side of trail to keep water from running over hillside further eroding the hillside. Hillside eroded to 2 1/2 feet of blacktop trail surface

135.82144+85grate/pipe - George's Drain Large drainage area with the grate. Two pipes about 30 feet apart one completely covered, 1 inlet, no fence. Covered pipe is deep - perhaps 4 to 6 feet below trail. 11/17 - (RAD PROJECT) - Area consists of compacted slag - cannot be dug out conventionally. Rockswhich blocked access to area were removed with many of them being placed overhill where water running over hill side eroded the RR hillside.
135.852013 slide6/29/2013 had big slide near here - look for overhanging rock (perhaps 135.89?). 2/25/18 small landslide came close to trail at 135.87. 6/11/18 more small landslide at 135.87.

135.94138+65137.44Pipe/slide-0.01. Big Digpla smo27Top of pipe was located about 5 ft below trail elevation with bottom of pipe 7 1/2 feet below trail area. (RAD Project)- Contractor says there are walls below ground which may be why drain pipe was so deep. Culvert built with metal cover with holes to permit water to go into culvert hoping to stop slide material getting into culvert. Top of culvert about 2 feet below trail. contractor offered to raise top of culvert one foot next year if needed at no charge. Heavy rain 11/5/17, culvert had temporary wooden top with limited holes. Rain water over flowed trail and flowed toward Pgh to drain 135.98. May need to dig ditch or add drain pipe allowing excess water to flow opposite direction to drain 135.91.

136.47110+01137.94pipe/fencevertical steel with slotsMystery Drain - two pipes on RR hillside, 6" and 9" in diameter and about 12 feet apart. On hillside drain area there is an upright large pipe with slits on the side. Bottom of pipe is full of dirt. Removed dirst from bottom of upright pipe. Found 9 inch pipe existing upright pipe. 11/5/17 observed rain water running out of 9 inch pipe with rain water swirling in upright pipe goinginto 9inch pipe. Large 12 metal pipe on RR hillside - cannot find in drainage area. Also on 11/5/17 observed rain water running out of 6 inch pipe of RR side of hillside. Have not found this pipe in drainage area. Both 6and 9 inch pipes are rusted out on RR side of trail. Water comes out of holes in pipe - waater does not make it to the end of the pipes. CAUTION: FOUND 16 INCH GAS LINE CLOSE TO FENCE - NOT UNDER TRAIL BUT IN DRAINAGE HOLE CLOSE TO FENCE ABOUT ONE TO TWO FEET DEEP.
136.54106+07138.03pipe/fencepla rib12Pipe Open - dam has been built in basin keeping most of slide material out of drain pipe. (RAD Project) Rocks placedup hill side to stop flow of slide material. Corregated pipe with some debris in pipe. NEEDS FLUSHED. 6/10/18 drain clogged with scree by 2 in. rain, causing waterflow along trail for ~100 feet.
Just north of 136.54, wide landslide slumped close to trail, filling swale, 2/25/18. Blums dug out. 3/26/18 spread grass seed & seed mats. 6/10/18 another slump.
