Carbon Canyon Road S-Curve Widening Zoom Mtg on 10 June

A virtual public meeting set up by CalTrans District 8 for the "State Route 142 S-Curve Project," proposing widening at this section along the summit on Carbon Canyon Road in Chino Hills and which would, many are concerned, allow for the rescinding of the large truck ban just recently enacted, has been scheduled on Zoom for Wednesday, 10 June at 5:30 p.m.

You can request to register by contacting: e&pengagement@icf.com.

For anyone living in Carbon Canyon or who regularly uses the state highway, this is a very important part of public input, so please consider joining and expressing concerns because there is no question that this project will be especially invasive if it involved allowing larger trucks again.  This road should not be used as a large truck route, but one wonders if there is pressure to make it one no matter how detrimental it would be to our communities in Brea and Chino Hills, as well as to the Canyon.

If there is such a plan, what is obviously needed is a coordinated response like Hope for the Hills undertook to fight back against the Southern California Edison TRTP transmission lines some 15 years ago.  That movement was successful and it would take the same type of effort to push back against what might be unreasonable and unwarranted project that serves narrow, though deep pocketed, interests at the expense of broader community concerns.

This post was edited following a comment on the Chronicle Facebook page rightly calling for attention to the facts—we would add, as we know them now, pending further revelations.  In the meantime, the CEQA Initial Study may be worth reviewing before the meeting on the 10th.

And, just found this Chino Valley Champion article, as well, note the statement by a CalTrans spokesperson that the ban may be rescinded once the widening project is complete
