Title
143rd Street - Noise Wall
History
The Village’s engineering team and its consultant are currently working on Phase 1 Engineering Studies for the eastern section of 143rd Street widening project. The eastern section is located between Wolf Road and Southwest Highway whereas the western section is located from Wolf Road to Will-Cook Road. As part of the environmental studies for this project, traffic noise was evaluated following federal and State project development procedures for the proposed improvements, as well as, the No-Build, or “do-nothing” option. That analysis found that, due to the proposed roadway improvements and predicted future noise levels for the homes within the Courtyard subdivision, directly adjacent to 143rd Street (Compton Court intersection to First Midwest Bank driveway), justify the installation of a noise wall. The noise wall will mitigate noise impacts to nine residential homes. The proposed wall will be approximately 400 feet in length and 10 feet high. The actual style of the noise wall would be determined during the next phase of engineering.
Per State and federal noise analysis policy, the opinion of the affected resident’s regarding the desirability of such a wall is taken into account before a final decision is made on the inclusion of the potential noise wall in the proposed improvement. The nine property owners benefited by the wall will each receive one vote regarding whether they want such a wall or not. A Noise Forum is being held for benefitted properties on June 9th (via a zoom audio and video meeting) to explain the federal noise analysis process, the proposed improvement and potential noise wall. A property is considered benefited when the noise wall results in a noticeable reduction in noise level, which is defined as five decibels or more. Only properties “benefited” by a noise wall may vote in favor of or against the wall. Village ordinances or homeowner association (HOA) rules have no effect on whether or not...
