a tree is at risk of being removed

Scroll Down For Instructions

if you are worried about a tree that might be removed, know of a tree that will be removed in the future, or want to investigate a tree that's already been removed. Please use the guide below, and if you have any questions, don't hesitate to contact us at info@treeactionseattle.org.

Thank you!

Step 1

Determine the Address

If you already know the address associated with the tree, or a tree is located in the right-of-way, please skip this steps step. Trees in the right-of-way are managed by Seattle Department of Transportation (SDOT), whereas trees on private property are managed by Seattle Department of Constructions and Inspections (SDCI).

For trees on private property, first find it’s address so you can find the appropriate documents. To find the address:
  1. Go to the King County Parcel Viewer.
  2. Click on the Basemaps button at the top right of the map. Change it to the latest available aerial map to see the aerial imagery on the map.
  3. Type in a street address you know is near your tree in the text box to the leftmost on the same menu as Basemaps.
  4. Look for your tree in the satellite data and make a note of its official address.

Step 2

Find Land Use Protections

Some addresses have a higher level of SDCI protection, most notably if they are in Environmentally Critical Areas (ECAs). ECAs are discussed in detail in the FAQ at the bottom of this page.You can check if the address is in an ECA in order to know if the removal or tree work will need additional permits or a Vegetation Restoration Plan.
  1. Go to the City of Seattle ECA map.
  2. Type your address in the text box in the upper left corner. Sometimes trees span more than one lot so you may need to try adjacent addresses too.
  3. The Layer list on the right sidebar has two sections: “Layer list” and “Environmentally Critical Areas (ECAs)”. Choose any of the ECA layers available in the latter section to see if your address belongs to any of such ECAs.
  4. Look for your tree in the satellite data and make a note of its official address.

Step 3

For Private Property Trees, Find Tree-Related Permits with SDCI

If your tree is on private property, you will now search the SDCI website to find relevant permits, if any exist. Your goal is to locate all relevant documentation that makes the tree removal “legal” in the eyes of the city. If any documents are missing, this is our best chance to  delay or prevent the tree removal.
  1. Go to the SDCI Permit Site.
  2. Enter the address you found above, or search with a specific document ID if you have it, and click Go. Don’t leave the page until the search is finished. Sometimes trees span more than one lot so you may need to try adjacent addresses too.
  3. Sort by descending date by clicking on the Date column header until it shows a down arrow.
  4. Now you’ll have to dig into the documents. Information related to tree work can be in any document with the following “Record Type” (found in the last column of the table):
  • SDCI Tree Public Notice
  • Construction Permit
  • Demolition Permit
  • Master Use Permit
  • Arborist Report
  • Treecycle Letter
  • Code Compliance Complaint

what's next?

After you collect documentation in steps 1 – 4

Now that you have all relevant documentation, it’s time to check for any errors, deceptions, or falsehoods.

We have experienced developers intentionally providing an incorrect (much smaller) measurement of a tree’s diameter, hiding arborists’ reports, or saying a tree is sick when it’s healthy in order to get a permit to remove it.

To save trees, it’s important to dig into these records and fact-check them with your own photos, measurements, or aerial data from the King County Parcel Viewer.

Make a Complaint to SDCI or SDOT

Now that you have all relevant documentation, it’s time to check for any errors, deceptions, or falsehoods.

We have seen construction companies intentionally providing an incorrect (much smaller) measurement of a tree’s diameter, hiding arborists’ reports, or saying a tree is sick when it’s healthy in order to get a permit to remove it.

To save trees, it’s important to dig into these records and fact-check them with your own photos, measurements, or aerial data from the King County Parcel Viewer.
400 Ward St, Seattle
Suki the snowy owl perches on a tree in South Queen Anne. A construction company tried to illegally remove this tree. SDCI didn't respond to complaints from neighbors, even though the tree was in their jurisdiction and their complaint line was open. Eventually SDOT stepped in to save the tree.
