Clyde Hill tree rules: what to check before cutting or building

Does every private tree need a removal permit?

Clyde Hill's published rules do not lay out a general private-tree retention percentage or a standard citywide replacement ratio like those used by some neighboring cities. The main tree-specific chapters instead address street trees and disputes over views and sunlight. That is not a blanket clearance to remove every tree on a construction site.

Before clearing, ask the City whether the particular tree is affected by a critical area, an existing development approval, a recorded restriction, or another site-specific condition. Confirm ownership and check title documents too. Get that answer before demolition or excavation makes the decision irreversible.

Start with the City's tree and view guidance and describe the actual tree, location, and proposed construction.

Street trees need a separate City check

The public right-of-way can extend well beyond the pavement. A tree beside your lawn or driveway may still be a street tree; the fence and curb are not reliable property boundaries.

Chapter 8.21 regulates planting and care of street trees and prohibits unauthorized removal or damage. Adjoining owners have maintenance responsibilities, and planting must use City-approved species and locations with appropriate visibility and utility clearances. Paying for maintenance does not give an owner unrestricted removal rights.

For a new driveway, utility trench, or construction entrance, ask the City about tree preservation and any required authorization before hiring a crew. Include root protection, equipment access, and material storage in the construction plan, not just a promise to leave the trunk standing.

Read the street-tree rules in Chapter 8.21 before work near the road.

Tall hedges have height limits of their own

Clyde Hill generally limits living fences to eight feet above original grade. Constructed fences generally have a six-foot limit. A closely planted barrier of vegetation may be a living fence even if each plant could also grow into a tree.

Along 84th Avenue NE, NE 12th Street, and SR 520, special arterial-road provisions allow constructed fences up to eight feet and living fences up to ten feet, measured from the higher of the arterial or original grade. Other arterial situations and street placement rules have their own details; do not apply the ten-foot exception to every roadside hedge.

Front-yard fences generally need a two-foot setback from the right-of-way for landscaping, subject to the code's exceptions, and cannot interfere with traffic visibility. Confirm the classification, measuring point, and location with the City before planting a permanent privacy screen.

See Chapter 17.37: fences and living fences for the exact limits and exceptions.

A blocked view does not let you cut a neighbor's tree

The City's view and sunlight chapter offers a process for certain previously enjoyed views or sunlight later obstructed by private trees. It starts with neighbor discussion and proceeds through arborist and mediation steps before a possible hearing. It is not permission to enter another property or order tree removal yourself.

The view chapter has its own tree-height and historic-tree exemptions. Do not mistake an exemption from a view complaint for a general tree-removal prohibition. Likewise, being eligible for a complaint does not mean removal will be ordered.

Our separate Clyde Hill view-protection guide explains eligibility, evidence, the process, and who may pay.

Keep construction away from roots you want to keep

Even when removal is not required, a foundation, retaining wall, drainage trench, or temporary access road can damage a tree you intended to preserve. The visible trunk is only a small part of the problem. Compaction and changes in grade can cause damage that shows up well after construction.

Have a qualified arborist assess important trees early and recommend protection distances and methods for the actual species and condition. Coordinate that advice with the architect, civil engineer, and builder before fixing the footprint. For boundary trees or roots extending from a neighbor's tree, resolve ownership and legal questions before cutting or trenching.

The City's tree page and urban forestry resources are useful starting points for arborist help and planting guidance.

Choose new trees for their mature size

A small nursery tree can become a large view, maintenance, or root conflict. Think about its mature height and spread, distance from buildings and utilities, the sunlight your rooms need, and neighbors' existing views. Planting choices made during a new-home project can create years of avoidable trimming.

Choose species and locations with an arborist rather than assuming every fast-growing evergreen is a good privacy screen. Where vegetation functions as a living fence, plan for the legal maintained height. Keep a record of any neighbor agreement about future maintenance.
