Jul 12, '10Rain Drainage and root systems at a Lake Oswego home

Today was one of those days that make being an arborist exciting: an opportunity for preservation via thoughtful planning…

I had the opportunity to meet with a new client in Northwest Portland, and walk his 1-acre property with him for a thorough discussion of his entire landscaping and tree care strategy. He had called with a couple of specific concerns about three particular trees, but we had a great opportunity to review his entire site thanks to some lucky conditions.

The previous day, more than 2 inches of rain had fallen, and the amount of water moving behind the house and around the site was amazing, leading to some great discussion of landscape design drainage techniques and how to maintain the tree canopy so that the hydrology on the property is not altered. It was a great example of a varied canopy of species indigenous to our specific Willamette Valley environment, a small number of trees that are native to the Northwest (but not necessarily the Willamette Valley); and the canopy also included some well-placed exotics (non-native species) that have naturalized well. We were able to examine the entire canopy, and classify the trees as dominant, co-dominant, sub-dominant and suppressed; we discussed removing most of the suppressed trees to improve the site ecology and help with fire prevention.

We examined the three trees that had led to initial concerns: A Western Red Cedar and an Oregon Ash were leaning precariously towards the house, and a large co-dominant Red Alder was showing exposed roots on the down slope side. We determined it would be best to remove the Cedar and the Ash for safety, but that the Alder could be left for the time being, hopefully saving the tree.

Our thorough discussion and examination of the entire site provided a great way to strategize and plan for the long-term health of the trees and the entire property’s landscaping. We were able to address the immediate concerns, while alse developing a long term plan with a schedule for implementation that would nurture the entire landscape and work well for the client. At Springwater Arboriculture, we strive to find the best possible balance between preservation of your beautiful trees and a safe forest canopy. This site consultation was a great example of the ways that a thorough consultation can create an outstanding long-term benefit for your entire landscape and canopy.
