Portland Tree Consulting

"Portland Tree Consulting works with developers, builders, engineering firms and architects. We make tree inventories of building sites and classify trees by species, size and condition and determine where they fit into City Code requirements. We identify trees that must be preserved and determine protection measures to accomplish this.
On a smaller scale, we help homeowners with individual tree removal and tree pruning permits. We also write tree protection plans for house additions and remodeling when they are required by municipalities. We have been doing this work since 1997 from the Multnomah Tree Experts platform. Portland Tree Consulting performs consulting only, not tree service work."
