Each engineered footing will be built across the back of the yard, approximately 70ft in length. The soil at each footing will be compacted after excavation. Construct two gravity retaining walls with milsap stone on engineered footings. The lower wall will be 4ft tall with a /ft wide stone cap on top. The upper wall will be 2ft tall with a 1ft wide stone cap. The walls will be backed by rip rap and contain 2" pvc pipe every 10ft for appropriate drainage. Existing fence will be removed and replaced in sleeves built into the new retaining wall. This will avoid future corrosion by not being buried in soil. Once the walls are built we will backfill the area with excavated dirt and compact to avoid any future erosion. We will also make any necessary modifications to existing sprinkler system in affected area. Josh Knight 214-228=8013 f 00931 .
