Sediment and Sand

Although the January 25th meeting of the Hahamongna Watershed Park Advisory Committee was well attended, it was a low-key affair. Folks were calm and polite. But if there had been any sand at Casita del Arroyo, one might have seen toes drawing lines in it.

Many citizens don't want Hahamongna to be another Arcadia Woodlands disaster,
LA County is all set with its Post Station Fire Sediment Removal Project for Hahamongna
and
the Committee (HWPAC) has procedures to follow. It's not always easy to know which way they're going to go.

But Tuesday night their toes were showing.

Highlights of the discussion:

Past Committee chair Tim Wendler expressed that he would like to see alternatives to the current plan that would "cause less environmental impact." (Basically, the 50 acres just north of Devil's Gate Dam will be freed of vegetation and kept that way, if the County is true to its word.)

LA County's Ken Zimmer said there are no alternatives to the plan.

Apparently not satisfied with Mr. Zimmer's answer, a Committee member whose nameplate I couldn't see asked him if alternatives had been studied.
He said there were no alternatives.
The Committee member rephrased her question. "Did the County study the possibility of reinforcing the [Devil's Gate] dam without tearing out acres of wildlife?"

"That possibility was not studied," said Mr. Zimmer.

The committee asked the County to return with alternatives to the current plan. Whether the County will do so remains to be seen. Maybe they don't have to. Maybe they can just kick that sand in the public's face.

Obviously I don't have a good feeling about this. I hope to be proven wrong.

The next meeting is currently scheduled for March 22nd, 6pm. As soon as I know the location, I'll notify you.

UPDATE:
THIS JUST IN from Altadena Patch:
If you want to find solutions and prevent the destruction of Hahamongna Watershed Park, come to an organizational meeting of environmental activists:

• Where: 1750 N Altadena Dr, Pasadena, CA 91107 (Eaton Canyon Nature Center)
• Date: January 29, 2011
• Time: 10:00am

• In the wake of the destruction of the Arcadia Woodlands and concerns over the sediment removal plans for Hahamongna, a group of local environmentalists are meeting to discuss forming a local environmental coalition.
  The idea would be to have a group that could help influence public environmental policy in a positive direction.
  Members of the local Sierra Club, Audubon Society, and other organizations will be in attendance.
  The meeting will take place at the Eaton Canyon Nature Center.  All are welcome.

WTF

The Hahamongna basin fills up with rain and silt every year. The Devil's Gate Dam has a job to do--keep all that stuff from flooding Pasadena, South Pasadena and beyond.

The Los Angeles County Department of Public Works Water Resources Division Flood Control District (LACDoPWWRDFCD for short) has a job to do, too--keep the dam in working condition.

Well, the LACDoPWWRDFCD's been busy, you know? So many dams (14), so little time. The sediment behind the Devil's Gate Dam has been building for some time and could have continued to do so. But the 2009 Station Fire scorched the mountains so severely they couldn't retain their soil. In early 2010, along with ash and debris, it all came flowing into the basin by the ton. Actually, it came by the cubic yard--almost a million of 'em.

Last year was an average rain year. Another year like it will bring the dam near to "uncontrolled flow at the spillway," according to Ryan Butler of the LACDoPWWRDFCD. Last Tuesday, Butler and Ken Zimmer of the LACDoPWWRDFCD presented the Postfire Sediment Removal Project (PSRP) at a meeting of the Hahamongna Watershed Park Advisory Committee (HWPAC).

Beginning in September of 2011, long after this coming winter's rain (which, you may recall, could bring the dam near to "uncontrolled flow" if it's an average year), the LACDoPWWRDFCD will first create a road into the basin from Oak Grove Drive near La Canada Flintridge High School. Then they'll remove 15 acres of native willow trees from the basin. By then they figure the rains will set in so there probably won't be much sediment removal next fall and they'll cease working until the spring of 2012.

Then (two rainy seasons from now, I guess we should pray for drought?) the emergency work begins in earnest. That will be 300-400 trucks per day, 7:30am-5pm Monday through Friday between May and December, hauling sediment out of the 50 acres closest to the dam to sites in Irwindale and Azusa. The job is expected to take 3 years at a projected cost of $35 million.

The "emergency" status of this project gives the LACDoPWWRDFCD a California Environmental Quality Act (CEQA) exemption, meaning an Environmental Impact Report (EIR) isn't required (even though there's still more than a year to do it--but you know, so many EIRs, so little time). The LACDoPWWRDFCD still has to get permits from the California Department of Fish and Game (CDFG), the Los Angeles Regional Water Quality Control Board (LARWQCB) and the US Army Corps of Engineers (USACE). Each of these agencies may require some sort of mitigation, environmentally speaking.

More questions will be asked. The city of La Canada Flintridge will have to weigh in. Mary Barrie of Friends of Hahamongna wrote an excellent report about the LACDoPWWRDFCD presentation. Arroyo Seco Foundation Managing Director Tim Brick expressed, among other things, his belief that this should be an issue in our upcoming municipal elections.

The stuff's gotta go. But does it have to go like this? The outgoing chairperson of the HWPAC, Tim Wendler, asked if other plans were considered before this one was chosen. "There's not a lot of options," said the LACDoPWWRDFCD's Zimmer. He added, "Deferring clean-outs doesn't work." Seeing as the LACDoPWWRDFCD has been deferring clean-outs for some years now, I guess we could say we have proof that he's right. Zimmer had the second-best line of the evening when he said, "Believe it or not, this is the fast track of the county."

The best line of the evening came from HWPAC member Maria Isenberg: "Can we get rid of that nasty little soccer field?"

I will bring you good news about Hahamongna later this week, I promise.

Here's good news about the PDP/PPM Contest:
Steve Scauzillo of Temple City (Daily Photo) is this week's winner of the PDP/PPM books contest! Steve was among those who answered correctly, "Who were the original architects of Pasadena City Hall?" It was the San Francisco firm of Bakewell and Brown. I took this week's poo bag to the Pasadena Farmers' Market and asked the beautiful daughter of one of my favorite merchants to draw a name at random from the correct answers. Steve won a copy of the lovely book At Home Pasadena from Prospect Park Media.

UPDATE: here's the county's sediment removal project.
