Noise Analysis ▲ Noise analysis warrants sound walls ▲ Meets Feasible and Reasonable criteria under FHWA ▲ Results indicate walls reduce noise levels of at least 5 dBA

Noise Analysis Process ▲ Noise levels are modeled – Calibrated with noise measurements ▲ 2016 traffic count data used in the model – Average Daily Traffic – 24,000 ▲ Actual speed limit of 40 MPH ▲ Truck mix based on field data

Recommendations ▲ Combination of 9-foot and 6-foot walls ▲ Replace existing backyard walls
