Abstract

This memo provides background in support of the noise section of the North-South Corridor Study Tier I Draft Environmental Impact Statement. The information included herein has been largely excerpted from the North-South Corridor Study draft Noise Report, which was prepared for the project-level DEIS, prior to conversion to a Tier 1 DEIS. As the project proceeds to Tier 2 studies, and the design options are refined, additional noise analyses will be required to determine the need for noise-abatement measures.
