Details: Maximum height ~8 ft. Total Wall area of 3500 square feet built in fall of 2004.
Description: This project was built parallel to the 9.3% grade eliminating the usual steps at the top of the wall all so that elevation changes are buried at the wall base. Also, the sleeves for the hand rail were installed during wall erection saving time, money and eliminating the potential problems associated with drilling directly behind the wall face.
