Phase 2 Traffic Study
On February 27, 2018, the City hired Iteris, Inc. (Iteris) to perform the second phase of this study. This phase focuses on the large truck traffic issues and also proposes short and long term improvements to overcome some of the traffic and safety challenges in the Carbon Canyon corridor.
Iteris completed a draft of the second phase study report in October of 2018 and the report received support from the City of Brea’s staff. On January 9, 2019, staff and Iteris presented the draft study to the Public Works Commission and received their support in submitting it to Caltrans. At this meeting, several residents provided input regarding the study, which will be thoroughly evaluated and considered. The January 9, 2019 presentation provides a good overview of the potential solutions and can be accessed via the following link: January 9, 2019 Presentation.
Prior to submittal to Caltrans, the Councils of both cities must adopt resolutions which request Caltrans to restrict large truck traffic from this roadway. The study and the resolutions are then submitted to Caltrans for their formal review. Once reviewed and approved, the local Caltrans Districts (Districts 8 and 12) will forward the study along with a recommendation to their Headquarters in Sacramento for final approval. This process may take several additional months, if all proceeds as desired.
On March 26, 2019, the Chino Hills City Council adopted a resolution which requests Caltrans to prohibit excessively large sized trucks from utilizing this highway. And, on June 4, 2019, the City of Brea adopted a similar resolution. Both resolutions, along with the completed study, were submitted to Caltrans on June 19, 2019. The City is driven to successfully complete this challenge and we are fortunate that Caltrans has been a supportive partner on this effort. However, the timing will continue to depend upon their review and any additional (or unforeseen) steps.
