It is the responsibility of the homeowner to properly maintain the street trees, or boulevard trees, located on your property. This includes pruning to height for pedestrian clearance, thinning, watering, leaf cleanup, and tree replacement – if needed.

These are designated as “Street Trees” by the City of Duvall and therefore, fall under the Tree Protection Ordinance implemented in 2018 and must be replaced if dead. If one or more of your trees needs to be removed, you must obtain a permit from the City prior to work commencing.  According to the city ordinance, trees should be spaced at a minimum on 25′ apart and a maximum of 40′ apart.  This may mean that you need to replant trees in a different location.

The original Autumn Maple street trees are susceptible to verticilium wilt and may need to be replaced.  The HOA board had an arborist inspect the trees on NE 150th, and she provided the following information that you can use when looking at your own trees to understand if they will soon need to be replaced.  Look for the following in your trees:

1. Extensive girdling root damage

2. Presence of buttress and stem decay

3. Presence of fungal fruiting bodies

From the arborist, “At this stage of advanced decay and long-term damage no mitigation measures are recommended to try to

“save” the trees. The cost would be prohibitive and likely unsuccessful.”

Additionally, the new street tree(s) is to be planted per the city ordinance, within one year of removal of the dead tree(s). Removing street trees, or any other exceptional trees for that matter, from your property without City approval may result in fines imposed by the City. For information regarding new trees, please refer to the Replacement Trees tab. 

Duvall City requires that replacement trees have a caliper diameter of 2″ at chest height. 

The Duvall City tree municipal code can be found here.

In the event that a street tree requires replacement, the Board has consulted with arborists and the city of Duvall to determine a list of approved replacement trees. The trees on this list were selected based on consistency in size, foliage, and coloration when compared with the existing street trees in the neighborhood.

Duvall City requires that replacement trees have a caliper diameter of 2″ at chest height. See the links below for pictures and additional information on each tree.
