CONCLUSIONS AND RECOMMENDATIONS
Case 1 — At a setback of 20 feet, the lowest resulting static condition safety factor of
2.30 exceeds the MLRB minimum requirement of 1.50 for an embankment adjacent to a
critical structure. The lowest resulting pseudo-static condition safety factor of 1.82
exceeds the MLRB minimum requirement of 1.30 for an embankment subject to
earthquake loading. The proposed setback of 20 feet from the fence is satisfactory.
Case 2 — At a setback of 11 feet, the lowest resulting static condition safety factor of
2.22 exceeds the MLRB minimum requirement of 1.50 for an embankment adjacent to a
critical structure. The lowest resulting pseudo-static condition safety factor of 1.79
exceeds the MLRB minimum requirement of 1.30 for an embankment subject to
earthquake loading. The proposed setback of 11 feet from the fence is satisfactory.
Case 3 — At a setback of 50 feet, the lowest resulting static condition safety factor of
2.40 exceeds the MLRB minimum requirement of 1.50 for an embankment adjacent to a
critical structure. The lowest resulting pseudo-static condition safety factor of 1.88
exceeds the MLRB minimum requirement of 1.30 for an embankment subject to
earthquake loading. The proposed setback of 50 feet from the fence is satisfactory.
Case 4 — At a setback of 40 feet, the lowest resulting static condition safety factor of
2.42 exceeds the MLRB minimum requirement of 1.50 for an embankment adjacent to a
critical structure. The lowest resulting pseudo-static condition safety factor of 1.87
exceeds the MLRB minimum requirement of 1.30 for an embankment subject to
earthquake loading. The proposed setback of 40 feet from the fence and lift station is
satisfactory.
Case 5 — At a setback of 28 feet, the lowest resulting static condition safety factor of
2.42 exceeds the MLRB minimum requirement of 1.50 for an embankment adjacent to a
critical structure. The lowest resulting pseudo-static condition safety factor of 1.89
exceeds the MLRB minimum requirement of 1.30 for an embankment subject to
earthquake loading. The proposed setback of 28 feet from the sanitary sewer, the
closest structure, is satisfactory.
Case 6 — At a setback of 31 feet, the lowest resulting static condition safety factor of
2.76 exceeds the MLRB minimum requirement of 1.50 for an embankment adjacent to a
critical structure. The lowest resulting pseudo-static condition safety factor of 2.05
exceeds the MLRB minimum requirement of 1.30 for an embankment subject to
earthquake loading. The proposed setback of 31 feet from the water line, the closest
structure, is satisfactory.
