Noise Variance Request for Nighttime Work on I-70 to be Heard in August

Public input and commentary encouraged and welcomed ~

(DENVER) – To allow for robust feedback from the community, the request for a noise variance for nighttime work on the Central 70 Project in Denver has been moved from July 11th to August 8th, 2019.

As previously announced, Denver’s Board of Public Health & Environment  received a request from Kiewit Infrastructure Company for a variance to Denver’s Noise Ordinance (Chapter 36 of the Denver Revised Municipal Code) associated with planned nighttime work from 2018-2022 on portions of I-70 that pass through Denver.  

This request will be heard at the Board meeting on Thursday, August 8th at 5:30 p.m. in the Parr-Widener Community Room (#389) in the City & County Building (1437 Bannock Street). Moving the hearing to the August meeting of the Board provides more time for public commentary regarding the variance request.

For more information on hearings before the Board of Public Health & Environment, please view the Board’s Rules Governing Hearings.

To conform with the Board rules applicable to a variance request, the Denver Department of Public Health & Environment (DDPHE) will provide a written response to the Board by Monday, June 24th by close of business and will defer a final recommendation for approval or denial until July 26th so that additional information may be considered.DDPHE’s recommendation regarding the variance request will be posted on this page on or around July 26th. 

Members of the public may provide input to DDPHE for consideration in the recommendation for approval or denial of the variance, and input to the Denver Board of Public Health & Environment regarding their consideration of the overall noise variance request.  Input received by July 23rd will be considered in the Department’s recommendation; input received until August 7th will be considered by the Board.

The variance request and associated exhibits are available for review here. 

To provide input,  you may send an email to, or send via regular mail or in-person to: DDPHE or DDPHE Board, 101 West Colfax Avenue, Suite 800, Denver, CO 80202. Note: All information received will be shared with the Board and DDPHE. Such information will be considered a public record, although the names and contact information of individuals will be redacted prior to releasing any requested records.  


On September 6, 2018, the Denver Department of Public Health & Environment Board ruled that the initial variance for this work be approved with the recommendations provided by DDPHE and an amended duration of 12 months (instead of the 52-month timeframe requested). As part of the approval of the variance, DDPHE agreed to monitor noise levels in the construction area and provide monthly updates to the Board on the project.
