Pacific sits on the lower White River and has flooded repeatedly, most recently when a levee breached in December 2025, so crawl space mold here often follows river water. Removal means getting the space dry, removing soaked insulation and ground cover and cleaning the framing before repairs.

A river town
Pacific is a small city between Auburn and Sumner, about 25 miles south of Seattle, mostly in King County with a small part in Pierce. The lower White River, also called the Stuck River, runs along its east side. Record November rains in 2006 pushed the river over its banks along Pacific City Park and created a temporary 25-acre lake. On Jan. 8, 2009, water releases from Mud Mountain Dam caused rapid flooding with virtually no notice. Then early on Dec. 16, 2025, a White River levee built of HESCO barriers breached, flooding a large part of the city; more than 200 homes were affected and over 600 people were displaced.
What to do now
- Stay out of the crawl space until power to wet areas is safe and standing water is gone.
- Pump or let the water drain, then open the space to start drying; EPA says assume mold if a flooded home couldn't be dried within 24 to 48 hours.
- Photograph the water line, silt and damaged insulation for insurance and permit records.
- Don't run a forced-air furnace whose ducts sat in floodwater until it has been checked.
- Keep children out of cleanup, as EPA advises, and wear at least an N-95 respirator if you go in.
- Before rebuilding, ask the city which permits or floodplain approvals your repairs need.
Signs and what they point to
| What you see | Likely cause |
|---|---|
| Silt layer on the ground cover | River water entered the space |
| Batts heavy, dripping or on the ground | Insulation soaked during the flood |
| Growth spreading upward from the sill | Framing that stayed wet after the water dropped |
| Musty smell returning weeks later | Hidden wet material or soil that never dried |
Cost factors
Angi's Seattle cost guide puts crawl space mold work at $425 to $1,650; HomeGuide's 2026 national range is $1,500 to $4,000. Flood jobs in Pacific usually land higher in those ranges because of silt removal, full insulation tear-out, duct checks and replacement of rotted framing. The City of Pacific says repairs to flood-damaged property need building permits and/or floodplain development approvals, issued through Community Development, and that homeowners insurance does not cover floods.
