When does drainage work need a permit in Everett?
Ecology's Stormwater Management Manual for Western Washington (SWMMWW, 2024 edition) is the state floor. A municipal stormwater permittee may instead adopt a REGIONAL manual Ecology has determined equivalent, and most do — some counties publish their own, some cities publish their own, and others adopt Ecology's directly. WHICH MANUAL APPLIES IS A PER-JURISDICTION FACT and it changes the numbers: review thresholds for new plus replaced impervious surface and for land-disturbing activity differ between manuals, so read this jurisdiction's own adopting chapter before quoting one. Critical-area and closed-basin parcels get stricter review under every manual.
From Everett's own code
“Exemptions to the minimum requirements for new and redevelopment are provided in the Stormwater Management Manual for Western Washington. In addition to those exemptions, project sites, or portions of project sites, that potentially contribute stormwater to the city’s latest designated combined sewer system (as set forth in EMC 14.08.040(B) ) shall not be subject to this chapter. The combined sewer system routes stormwater for treatment at the publicly owned treatment works.”Source ↗verified 2026-04-26

Notes & caveats
Issuing body is city public works / county DPER, often parallel to the building permit. On-site infiltration / detention required where infeasible to discharge to municipal storm. Critical-area parcels (steep slope, salmon-bearing watercourse) get more conservative review.
