Noise Monitoring Reports 

The Project will include intermittent night work on and adjacent to I-70 between Brighton Boulevard and Chambers Road throughout construction. Night work in residential areas must follow specifications set out in a variance approved by the Denver Board of Public Health and Environment. The initial noise variance request was approved for one year in September 2018 and is reevaluated annually.

Night work must stay under 75 decibels, based on an hourly average. Work may occur from Monday through Friday from 9 p.m. to 7 a.m. and Saturday and Sunday from 5 p.m. to 8 a.m.

General construction may not occur in the same residential area for more than five consecutive nights in a 7-day period.

When major construction activities are scheduled where noise levels are expected to exceed the variance levels (such as bridge demolition), hotel vouchers will be offered to impacted residents defined by an established boundary. Major construction activities may not occur for more than three consecutive nights.

The Central 70 team is committed to being a good community partner and will closely monitor noise to ensure requirements are being met. Project sound barriers have been installed near the I-70 viaduct as an additional noise reduction method. Colorado Department of Public Health and Environment (CDPHE) regulates the noise variance and residents may contact the city at 311. There is additional information about the variance here
