The Central 70 team is committed to being a good neighbor by closely monitoring construction noise levels. Learn more about noise and vibration and how it’s monitored.

The Central 70 Project is seeking a renewal of their Noise Variance Request from DDPHE on Thursday, Aug. 12, 2021 at 5:30 p.m. The location and format of the meeting is to be determined. The public may provide input to DDPHE for consideration of the variance through July 16, 2021 or they may provide input to the Board of Public Health and Environment (BPHE) regarding the overall variance request by Aug. 11, 2021. Send your input via email , by mail/in-person to: DDPHE or BPHE, 101 West Colfax Avenue, Suite 800, Denver, CO 80202, or leave a voicemail at 720-865-5392. No personal information is required if you wish to remain anonymous. Learn more and view the variance request

The Central 70 team is committed to “clean” construction throughout the duration of the Project, not just by mitigating dust and noise, but also by monitoring air quality. Learn the details! 

*The following Air Quality Monitors have been relocated to new locations:

• 46th and Vine Street; and
• Southeast of I-70/Quebec Street

The Monitor on 46th and Vine Street is now located on 46th and Gaylord, which is approximately 350 feet northeast from the original location. This Monitor relocation was necessary for storm line construction work. The Monitor located at Quebec is now located approximately 400 feet south of the original location for the permanent water quality pond. 


Environmental Sampling of I-70 Viaduct

Prior to awarding the Project, CDOT conducted an environmental sampling of the viaduct. Based on their sampling, no lead paint was identified. Kiewit Meridiam Partners (KMP) completed a second and more thorough inspection and sampling of the viaduct in December 2020. The results of those reports can be found here

Listed below are the CDOT lead sampling results from the viaduct, KMP’s Health and Safety Plan specific to the management of structures with lead and heavy metal paint as well as a document highlighting the environmental sampling and abatement process as it pertains to demolition. If any of our supplemental sampling of the viaduct identifies the presence of lead paint, we will review and further develop an abatement plan specific to the identified location and operation.
