Environmental Document Completed for C-470 Corridor

November 30, 2015 - Denver Metro/CDOT Region 1 - A Finding of No Significant Impact (FONSI) has been signed by the Federal Highway Administration (FHWA) and Colorado Department of Transportation (CDOT).

DOUGLAS COUNTY – A Finding of No Significant Impact (FONSI) has been signed by the Federal Highway Administration (FHWA) and Colorado Department of Transportation (CDOT) as part of the C-470 Corridor Revised Environmental Assessment (EA) – Kipling Parkway to I-25 (November 2015).

CDOT and the FHWA are seeking to make improvements to C-470 that relieve congestion, decrease delays and improve travel reliability. Proposed improvements include adding one tolled express lane in each direction between I-25 and Kipling Parkway, and a second tolled express lane westbound between I-25 and Lucent Boulevard, and eastbound between Broadway and I-25. These new lanes, plus new auxiliary lanes where warranted, would supplement the existing non-tolled general purpose lanes. The project also includes pavement re-construction, alignment improvements and direct-connect ramps at the C-470 and I-25 interchange.

The FONSI follows the Revised Environmental Assessment, which reviews the environmental impacts of the project, including air quality, wetlands, noise, etc. In response to public comments received regarding long-term noise measurements not required as part of the Revised EA, CDOT took five additional days of measurements.  These additional measurements support the noise conclusions documented in the Revised EA and were made part of the FONSI.

Additional information regarding the Revised EA and the FONSI is available at www.codot.gov/projects/c470ExpressLanes or by contacting CDOT’s Jerome Estes at 303-757-9295.

The FHWA will publicize a Limitation on Claims notice for the FONSI in the Federal Register in the near future.
