Because the beaver isn't just an animal; it's an ecosystem!

Day Four of the “Emergency bank stabilization”  that was estimated to take ten days. We have ten feet of sheet pile installed for a 200 foot project.  5% complete. You know that algebra thing “if five percent of a project can be done in four days, how many days will it take to complete the entire project?”

 

A lot.

 

The needed sheetpile is supposed to be delivered on Monday. Skip Lisle is supposed to leave tomorrow. Yesterday he was going to approach the city about staying at least through the lodge installation, which we entirely support. I talked with Igor Skaredoff (who is on the oversight committee) and he agreed it was a good idea, and said he would approach city staff about it as well. I have not yet heard the outcome, but as we wait I thought I would just remind regular readers (and first time readers!) that us “crazy beaver people” have a list of good reasons to be doubtful of this “emergency”. This was printed in the Martinez  Gazette yesterday.

 

A previous letter to the editor highlights the secrecy and delay of the Martinez City council, but falls short of describing the actual dishonesty that has taken place. Not only would there have been no emergency if the council had implemented our recommendations sooner, there is no emergency now.

 

In response to the February report alleging damage to the properties beside the creek due to beaver burrowing, the city issued a no-bid, unpublished, contract to a geotechnical engineer. He visited the site twice and released his report on September 9th outlining that there was no damage to either building, that there was some separation of the bank from the wall, and that this could be cheaply addressed through the installation of pressurized grout and re-vegetation.

 

The city reviewed his recommendations and their modest price-tag in private and promptly demanded the expert revisit the property. Apparently his solution wasn’t expensive enough, and his findings weren’t dire enough. The expert obligingly returned ten days later and reported that the situation had gravely worsened. The only lasting solution was a 500,000 installation of sheet piling.

 

His report contained no photographs of this “alarming change” which constituted an emergency. There was no effort to assess the structure, design or age of the wall and there was no explanation of why the separation of a bank from a wall would constitute an emergency in the first place.

 

Is it a retaining bank?

 

Worth A Dam hired Laurel Collins, a fluvial geomorphologist, who spent 4 hours inspecting the creek and bank on October 6.  She actually entered the water, which no expert had done. She identified a two-foot footing along the wall, which no expert had done. She assessed and documented each beaver tunnel, which no expert had done. She found the tunnels run parallel to the water as expected, not away from it as alleged. The footing is below the bank and likely predates the bank. There are no signs of stress from the slipping of the bank, which was never intended to “hold up” the wall. Ms. Collins’ report, which mirrored the city’s September 9th report, was obviously not dire enough either. For mysterious reasons, the city is committed to a large scale project along this bank, and made sure their expert report justified it as an emergency. As with the Iraq war “the intelligence was fixed around the policy”.

 

We can only watch to see what follows: residents of the sheet pile-weary Bethel Island might suggest that the vibrating hammer technique to be used will cause significant structural damage to the properties along side the creek. Savvy residents who have watched this debacle from the beginning are waiting for the restaurant Bertola’s to be deemed structurally unsound, for the building to be torn down, and the arrival of a plan to install an underground parking structure in its place.

 

In the mean time, experts take heed. When the city of Martinez asks you for recommendations, remember to give them the most expensive solution possible.

So today the final sheet of the small section between the bridge and the lodge was installed, but the others haven’t been delivered yet so the work has halted. We were told that the obstuction yesterday was from a “tree root”. The explanation was that if it had been cement the metal would have jumped around, sort of like it did today, when Bertola’s windows rattled and the building shook.

If that was a tree root, then this must have been the tree

(In case you don’t recognize the picture this is the “Tree of Life” from Walt Disney World, and um, it’s made of cement.)

For this morning’s efforts they couldn’t install the last pile towards the wall to close off the curve. There were too many “roots”. They thriftily used the “left over” sheet pile from yesterdays scraps to close the gap between the pilings and the wall. It is resting atop the footing and will be welded in place this afternoon.

Skip is slated to leave Saturday, and the sheet piles may not arrive until Monday. What could possibly go wrong?


Hard labor today saw the willow topped from the trees distributed into the creek where the beavers could reach it. Jon is walking a little stiff after all the carrying, but he was helped by one of the kind-spirited tree cutters. Our intrepid photographer Cheryl Reynolds was offered actual dollars for the pictures she will be submitting for the LA times article. Nice work. We got a donation from as far away as Germany and we found out that ESA students will be on sight to help observe the work Thursday morning.

Here’s proof that the non contact thermometer readings are working to help find beaver location in the lodge.

The warm spot indicates hot-blooded little beaver bodies, most likely the yearlings in the old lodge. This is a surface reading thermometer; obviously beavers have a higher temperature than 57.8 but they lean against the walls of the lodge and raise the temperature measurably.


Last night all four kits were in grand display at the footbridge, and we made a few delightful discoveries. One kit ducked under water near the second dam, where we’ve been seeing a little intriguing action. Then a young man noticed he “popped” out on the other side into the waterway dug by the flood plain work. He had a tunnel through the levy, and another exit near the footbridge where he emerged to check out the food his brothers were enjoying. Then he crossed over the packing material left by the city, obviously appreciating the ready-made dam.

This is good news because our beavers will need somewhere to hide out during next week’s horrors, and if they’ve already started a tunnel in that scrap of unloved land, maybe they can expand it into temporary housing. Today’s farmers market had a host of beaver support, ($120.00 in donations) and some intriguing conversations. Including the reporter from the LA times (!) and the Castro street resident who saw fish & game inspecting the creek earlier and asked why. He was told there were two dead dear in the creek from a probable Mountain Lion up behind the adult school. Hear that beavers? Stay down stream!

The highlight of last night though had to be the beaver-lovin’ family with young children who came down to see the animals, bearing a tiny beaver toy that made chewing noises. We thought that was cute enough but our hearts were melted when their daughter turned around and we saw she was wearing her lovingly preserved beaver tail from the from the festival in August. Cheryl asked permission to take this photo:

When we expressed our delight, she marched us out to the street where she had placed this handmade sign:

“Leave the beavers aloooooonnnnnnnnnnne”. Hmmm, anyone wanna make that video?

Ohhh PS, my computer tells me this is the 292 post on the web page. Lets hope when we get to 300 we still have beavers.


In preparation for tuesday’s construction, castro street between Marina Vista and Escobar was closed today, along with the lane nearest the bridge on both streets.

The work saw the first tree casualty as the forklift bringing the metal plates the crane will rest on knocked out a street tree. If it weren’t for our friends at the county building there would be no access at all, but at least a narrow path was left for them.

Worth A Dam was contacted today by Dave Scola to ask whether we would help Skip Lisle supplemental feed and help him to use the infra red temperature device we offered for lodge readings. He also said that when the trees are topped we will have access to the cuttings to decide whether they should be for feed or removed. I asked him to contact the city parks manager to identify other sources of Arroyo Willow we could cut along the creek.

Even if we are prevented from being anywhere close to the work, Worth A Dam will be on hand. We are armed with spotting scopes, walky talkies, infra red thermometers and spotlights. If the beavers can be protected, they will be.
