Hey there!
If you live in West Seattle and thinking about building something, you’ve probably heard about those ECA Steep Slope permits. Sounds complicated? Don’t stress — Team Alki Deck Builders has your back and handles the whole process for you.

What’s an ECA Steep Slope anyway?

Seattle has a lot of Environmentally Critical Areas (ECA) — places with steep slopes, unstable ground, or other sensitive features.
If your property has a slope of 40% or more, it likely falls into that category, and yeah — you’ll need a permit before building anything major.

But no worries — that’s where we come in.

How do you know if your property’s in a Steep Slope area?

You can check it yourself on the Seattle GIS Map.
or — way easier — just shoot us your address, and Team Alki Deck Builders will check it for you, no strings attached.

What happens if your lot is in a Steep Slope zone?

You’ll need:

• A geotechnical report (fancy word for soil & slope stability check);
• The right paperwork submitted to the Seattle Department of Construction & Inspections (SDCI);
• Patience — getting the permit can take a few months.

But here’s the good news — we handle all that.

How Team Alki Deck Builders helps:

• We check your property;
• Bring in trusted engineers for reports;
• Deal with all the city paperwork;
• Handle permit approvals;
• Build your project safely & legally.

Bottom line — you relax, we do the legwork.
