Diseased Tall Redwood Tree on Neighbor's Property
April 2016
I recently had my trees including a redwood tree assessed by three arborists. All gave me unsolicited feedback about the redwood tree in a neighbor's yard. That tree, without being able to directly look at the tree or its roots, said it was either diseased or had root damage given that the canopy that does exists covers top 1/3 of the tree and is in poor condition and the lower 2/3s is dead branches. This 90 foot tree is surrounded by several homes in a dense environment that also includes a synagogue.
I contacted the City of Berkeley to see if there's something they can do or if they have programs about helping property owners but have not heard anything.
Does anyone have any familiarity with this kind of situation. I don't know this neighbor since it's not someone who lives on my block. Their property abuts several properties on a perpendicular street (the yard is behind my yard). I would like to talk to the neighbor but think it would be best to be able to present helpful information to the neighbor.
Thanks! Anon
Go talk to your neighbor. In the time it took you to post this you could have already been done with the conversation. Tell the neighbor what you learned. DO NOT get the city involved until you know for sure that no action will be taken by your neighbor. If my neighbor had information like this, I would want to know it. And I would be horrified if my neighbor sicced the city on me instead of talking to me herself. Just knock on the door
Call your homeowner's insurance agent. They have a vested interest in this situation. They may be willing to approach the neighbor, if you would prefer not to.
Alternatively, you can get the names and some contact information for all the abutting neighbors either from the tax assessor's public records or by asking a real estate agent who does business in your neighborhood to look up the owners' names, after you provide the addresses.
If your property, and other properties, are at risk for damage if this tree falls over, perhaps the affected parties could share the cost of mitigating the situation. Amelia Sue
Sounds like you have a ticking time bomb. Are you living in a location where the tree could fall and kill you or one of your neighbors? This kind of stuff does happen. If the tree is as bad as you describe you should move out until it is safe. I would notify ALL of your neighbors including the folks at the synagogue.
Make sure the city knows and takes action including contacting the mayor and city attorney if needed.
Trees do fall. We had a huge 100 foot tree just topple over one afternoon. In December a falling tree branch injured someone in Oakland.
But let me share this. We have two friends in Oakland hills who had tree problems. One family had a 100-foot tree Redwood tree unexpectedly fall. These people had amazing luck as the tree just happen to fall exactly between there house and their neighbors. Had it fallen a few feet to the left or right it would have taken out either house. All they lost was a car and their mailbox.
Our other friends were not as lucky. They had a tree fall right through the middle of their house "cutting" the living room and master bedroom in half like a giant chainsaw. The entire family was at home at the time and had anyone been in the living room there is no way they would have survived. Had the tree fallen a few degrees in any other different it would have landed in the kitchen or kids rooms.
Not trying to scare you but treed in urban areas do fall and it's all a question of where it's going to land.
As far as I know the city doesn't have a program to help homeowners. They do have a responsibility to protect the public. ANON
Is the tree in danger of shedding branches, damaging property? If so, have an arborist give you a quote for what it would cost to have the tree cut down, and have them put in writing that the tree is in danger of causing damage. Then give this information to your neighbor. You say you don't know them, but if the tree causes harm to a neighbor's property they could be liable -- so it's probably better that they know.
I am going through a similar situation with a neighbor's tree, and likely we will wind up sharing the expense of having the tree removed. Though not a great solution, your neighbor might finally act if you and the other affected neighbors offered to contribute to the cost of having it removed.
chop it down!
Write them a letter, expressing your concerns. You might ask a City Arborist to weigh in. Taking a big tree down is expensive and emotional; to make it work you might have to (eventually) offer to split the cost with them. You could try mediation...
How to measure the height of a redwood tree
Aug 2009
We have a rather tall and very healthy-looking redwood tree in our neighborhood and the topic came up several times among the residents of how to measure its height. I suggested using el-hi math (measure dist to base, and angle to top), but the idea didn't take with the group at large. Anyone been in a similar situation -- did you hire someone to do this? Maybe you used a special tool? Nel
I like your suggestion. This is a simple trigonometric formula. Ht = base times tan of angle.
Another way, which might sit better with your non-mathematical more visual neighbors, is to use proportional triangles. Imagine a small triangle near the corner you are using for your angle. Measure the base and height of your small triangle and the base of the large triangle. The height will be proportional (H/B=h/b).
Of course both ways assume a 90 degree angle from the tree to the base line. Both will be quite accurate if you get a transit from the tool lending library to help. Andus
You could in theory use similar triangles. Put up a 10 foot stick next to the tree. Measure the length of its shadow. Measure the length of the tree's shadow. The ratio of the two shadows lengths is in theory the same as the ratio of the stick and tree heights. anon
We had a gentleman from Arborist Now come check out our redwood when we were worried about it, and he seemed very knowledgable and helpful. https://www.arboristnow.com/
We have used Tree Sculpture for consultation and also tree removal. Really nice, professional company, and their arborist Dan is great, takes time to explain everything, and knowledgeable. I tried going through another company and their rep didn’t even bother to come to my house to look at my tree, and their bid was much higher. Another company sent an arborist but he never bothered to follow up with a quote and didn’t reply to emails. Tree Sculpture was by far better. Highly recommend Tree Sculpture.
We were impressed by Traverso Tree Service. We had an ailing redwood, too.
