The City Council of Broomfield held a study session on August 19, 2025, focusing on traffic impact assessments and safety measures related to the proposed extension of SkyStone Parkway. The meeting featured discussions on updated traffic generation standards and the implications of changing travel patterns due to increased remote work.

A representative from the Institute of Transportation Engineers explained that traffic generation calculations are based on national data and regression equations, which provide consistent results regardless of location. The upcoming twelfth edition of the trip generation manual, set to be released next week, is expected to reflect changes in traffic patterns, particularly a decrease in morning peak hour trips due to more people working from home.

Council members raised questions about the study area for traffic evaluations, which included surrounding neighborhoods and anticipated developments. The traffic impact study accounted for all known developments in the vicinity, ensuring a comprehensive analysis of traffic movements.

Safety features for the SkyStone Parkway extension were also discussed. Proposed measures include raised crosswalks and narrowed lane widths to slow traffic. The new lanes are planned to be 11 feet wide, which is slightly narrower than the standard 12 feet, to help mitigate speed. However, some council members expressed concerns about the adequacy of lane widths for larger vehicles, suggesting that 10-foot lanes could be sufficient.

In terms of bike infrastructure, the plans include raised bike lanes on the new section of SkyStone Parkway, while existing sections will feature painted bike lanes to delineate space for cyclists. Council members emphasized the need for effective separation between vehicular and bike traffic to enhance safety.

The North Metro Fire District was also consulted regarding the necessity of the road extension for emergency response. While specific data was not immediately available, the fire district highlighted the importance of having multiple access points for efficient evacuation during emergencies, such as wildfires.

The council concluded the session by emphasizing the importance of updated traffic studies and safety measures as the project moves forward. Further analysis will be provided to the council once the new traffic generation manual is released, ensuring that all safety and traffic concerns are adequately addressed.
