Greenville-Banning Channel Project Explained

Last night, in the Costa Mesa City Council Chambers, a small group of residents heard from representatives of the Flood Control Design Section of the Orange County Public Works Department and City Staff about the plans for rehabilitation of a little over 3,000 linear feet of the Greenville-Banning Channel, which runs through Costa Mesa from the I-405 Freeway, across California Avenue to the Santa Ana River.
The project designer, Justin Golliher, guided the discussion and the PowerPoint presentation for the seven (7) residents who showed up for this meeting.  Approximately 250 homes received notices.  I only knew about it because of a press release issued by the City earlier in the day. Questions should be directed to Golliher at 714-647-3979
We learned that this project is only one in a $2 billion dollar backlog in work for the Public Works Department - which might take 90 years to complete.  The Flood Control group manages more than 370 miles of flood control channels throughout Orange County - more than the miles of roads the county manages.
This project will require the replacement of the New Hampshire Avenue bridge in its entirety.  The California Avenue bridge will be untouched.   This project is necessary to rehabilitate a crumbling channel in which decades of erosion has taken its toll.  The entire length will receive some kind of repair, which will be designed to manage that proverbial 100 year flood.
Many factors were considered when planning this project, as listed on the slide below.
The permitting process is overwhelming, having to deal with many governmental entities.
It is presumed that the permits might be obtained by December of this year.  The schedule below shows the anticipated time table, with completion optimistically planned for the winter months next year.
I thought it was interesting that when members of the public asked about community outreach the officials indicated that the contractor would be in touch with them.  They made it clear that "issues" with the contruction during the process should be directed to the contractor.

Clearly, the work needs to be done on that channel, which is certainly showing signs of possible failure if a large storm were to occur.  Questions were asked about standing water - there shouldn't be any.  That's an important issue since we hear more and more about mosquito-born illnesses lately.  County Vector Control will handle that problem.

A ditch currently runs parallel to South Coast Drive between it and the La Quinta Inn. Maybe officials would like to stop by today and see the standing water.

I'd like to add a bit of clarification to the "CALL THEM, NOT US!" section. OC Public Works definitely wants residents to contact our OC Construction Division if they have concerns during construction. OC Construction oversees the contractor during the project execution and is responsible for community relations during the construction period. If you have an issue, we want to know about it!

Prior to the start of construction a notice is mailed out providing contact information for the OC Construction staff and the contractor. I should have provided a little more information about how OC Public Works manages the construction contract because we are very involved in the construction process and evidently this was not conveyed.

Thanks for the clarification.

Thanks, Geoff, for reporting on this. Flood control is an important project, and I am glad to know it is starting.

The short notice for this meeting annoyed me. We pay extra for the (Righeimer created) City Employee position of "Communications Director" to send us an email at the last minute.
