Sandbagger creates and implements Stormwater Pollution Prevention Plans for commercial construction projects across King County — meeting DOE, EPA, and local requirements.
What Is a SWPPP?
Your Plan for Managing Stormwater — and Avoiding Fines
A Stormwater Pollution Prevention Plan (SWPPP) outlines how your construction site will:
Prevent soil erosion
Contain sediment and debris
Protect nearby water bodies
Stay in compliance with state and federal law
Most commercial projects in Washington require a SWPPP before excavation begins. We help you get it done right — and fast.

FAQs
Stormwater Plan FAQs
Is a SWPPP required for my project?
If your project disturbs one acre or more (or is part of a common development plan), you’ll likely need a SWPPP and a Construction Stormwater General Permit.
Do you file permits too?
We assist with permit documentation and submission, and we coordinate with consultants or city officials if needed.
What if my SWPPP needs to change mid-project?
No problem. We provide updates and BMP changes as your site conditions evolve — with full documentation.
