Whatcom County Code regulates tree removal in Critical Areas and their buffers, the Lake Whatcom watershed, the Lake Samish watershed, the Lake Padden watershed, and areas within 200-feet of a regulated shoreline.
Tree Removal in the Lake Whatcom, Lake Samish, and Lake Padden watersheds
A tree removal permit is required for the removal of any significant tree(s) (if the removal of the tree(s) is not associated with a development permit). You can get the Tree Removal Permit application at http://www.whatcomcounty.us/920/Applications-FormsLinks.
If trees are to be removed as part of a development permit, tree removal information will be required with the applicable development permit. A tree retention plan will be required to be submitted with the applicable development permit.
Tree canopy removal (whether it is associated with a development permit or not) may not exceed more than 35% or 5,000 sq. ft. of the tree canopy existing on site as of January 1, 2017 (measured cumulatively).
See WCC 20.51.430 and WCC 20.51.440 for tree removal in the Lake Whatcom watershed and WCC20.71.354 and WCC 20.71.356 for tree removal requirements in the Lake Samish and Lake Padden watersheds.
