Here are some pics to get a visual. My 1st wall install so I have a few questions. Here are the basics: 100' x 3' tall average. I plan on using a 6 inch crusher base and #57 backfill with drain pipe. Here is my delema: Would you backfill the whole 100'?. You can see RR ties in the pic. I plan on keeping the ties in place and building the wall in front of them. Backfill the wall in front of the ties or not? Also the junipers seem to be doing a good job of preventing water run off. I plan on removing some of the junipers to create 3 circular areas for crepe myrtle install with mulch, in the middle of hill. The only place I see water run off is to the left of RR ties. This area I suggested mulching the bare spot on slope to help control run off. I need the work and want to keep costs down, but want to do the job correctly to prevent further maintance in the future by clients or myself. Down here in the Southeast we can get some heavy rain due to tropical depressions in the fall.
