Concrete Retaining Walls in Camano Island, WA

Retaining walls in Camano Island: what to know

The county’s 2021 residential exemption list keeps a wall at four feet or less, running from the footing’s bottom to the crest, exempt from permit unless a surcharge is present. The copy we read says nothing about liquids or about engineering for walls, so those answers come from the county. Walls over the line are scoped to the county’s building permit process, which the county confirms for each parcel.

The footing depth and the crest are logged for each run, along with any bank, drive, or structure that pushes on the wall and how far it sits from the face. On parcels near the water, the wall’s outlet is checked against the county’s shoreline program before the section is drawn. Water collected behind the wall goes to a chosen outlet, and that outlet stays listed as pending until the county replies.

Permits and rules in Camano Island

Before a quote goes out, we confirm how Island County classes the wall, including whether a surcharge applies and whether the county wants an engineer’s design for a wall above 4 feet. Each load behind the wall is noted on the site plan with its offset from the face. The county’s answer is filed with the wall plans, and any pending item stays listed on the scope.

Rules change and vary by parcel, so we confirm the current requirements with the city before we start.

Questions from Camano Island homeowners

What wall height stays exempt on Camano Island?

The county’s residential list exempts a wall whose height from footing to crest stays at four feet or less, provided no load sits behind it. A loaded wall falls outside that exemption, so the load is measured before quoting.

Does loose soil stacked behind a Camano Island wall alter its permit status?

The copy we read gives no surcharge definition, so each load goes to the county before the layout is drawn. A load behind the wall takes it outside the exemption, which is why the answer shapes the quote.

Who confirms drainage for a Camano Island retaining wall?

The county is asked about any outlet that reaches the road or the water, and the design follows the county’s written reply. Until that reply arrives, the outlet stays marked as pending.
