One provision of the Oakland settlement agreement was a noise study (known as a pre-NBSSR study) along the Hwy. 24 corridor between Hwy. 13 and I-580. Wilson-Ihrig conducted the measurements and prepared this report.  Many locations along the corridor have sound levels above the 65dB ACCMA level qualifying for sound wall. Four segments received the highest grade for effectiveness.
