All of the traffic from Madrona would dump onto Carbon Canyon Road near the burned out horse stables between Sleepy Hollow and Olinda Village. There is no traffic signal planned at this time but it wouldn't come as a big surprise if the project created a need for one. Anyone who drives on Carbon Canyon Road at morning or afternoon rush hour knows how bad it can be already. Approval of this project guarantees that it will be worse.
Madrona would generate about 1,600 average daily trips onto Carbon Canyon Road. They reach this number because each additional house generates about ten vehicle trips a day. For example Dad goes to work counts as one trip; the gardener comes and goes, that is trip 2 and 3, Mom goes to and from the store are trips 4 and 5, etc.
Many of those trips would go to intersections in Brea that are already very bad. Morning and afternoon rush hour intersections that are guaranteed to get worse are: Carbon Canyon Road and Olinda Place, Imperial and Birch/Rose, Valencia and Lambert, Lambert and the 57, and everything in the middle. No traffic study was done on any intersection in Chino Hills. The study didn't seem to focus on the choke-point where Lambert goes from three lanes in each direction down to one. If you enjoy being stuck in traffic, Madrona is a project you will love.
The Madrona project will make traffic worse and there is nothing they plan to do about it because the cost of a remedy is too "burdensome" for the developer. In order for the Madrona project to be approved, the City of Brea must therefore issue a "Statement of Overriding Consideration (SOC)." That means the Environmental Impact Report has identified a significant and unavoidable negative environmental impact from the project that cannot be mitigated (fixed) but the City thinks the project benefits the community so much that it is willing to overlook FOREVER the negative impacts that will be generated by the project.
One of the three SOC's required for the Madrona project is traffic. The SOC must explain why the project is so good that traffic impacts can be ignored now and forever. The claim is that Brea needs more executive housing and these residents will buy a lot of stuff in Brea. Do you think it is worth it? The project is equidistant between The Shoppes in Chino Hills and Downtown Brea. Since La Floresta and Blackstone housing projects have not been completed, we do not yet know if the required traffic mitigations for those projects have been effective.
Traffic is given grades, much like students, and they are grading the Level of Service (LOS) at intersections, A,B,C,D,E, and F. (e.g. how many times do you sit through a signal) Here's an interesting quote from the EIR. "Levels of Service along Carbon Canyon Road are currently at acceptable LOS C or D, but are approaching theoretical capacity limits. Current peak hour conditions are approaching theoretical capacity and are considered highly congested."
Here's a quote from the EIR when the project was called Canyon Crest: "The City of Brea has established level of service (LOS) "D" as the performance standard for signalized intersections throughout the City's roadway network." But the project would push the intersection at Olinda Drive and Carbon Canyon Road from D to E. So they have decided to change the City of Brea General Plan standards, or change the way they are measured for this project. That's just wrong.
There is also the issue of the extra traffic during two and a half years of construction. This additional traffic, coming from the Brea side of the canyon, will affect Carbon Canyon Road and surrounding roads six days a week from 7 AM to 7 PM for two and a half years. And this does not take into consideration heavy rains, landslides, and possible fires that could render the road closed for extended periods of time thereby extending the impacts.
Recently it was learned that the road that will serve as a temporary construction road and as a secondary emergency exit is owned by Chino Hills State Park. The City of Brea has a public road easement over the Olinda Drive extension. Eventually that road will serve another housing development on land owned by Aera Energy. So if Madrona and the Aera project are someday built, Madrona residents will be watching Aera residents drive by on a public road they have a right to use. Brea has refused to analyze those traffic impacts that would likely bring hundreds of cars through Olinda Village as Madrona residents seek a short cut and use of the traffic light on Carbon Canyon at Olinda Place.
