Why Category 3 Hits Fort Lewis Hard
The pattern in Fort Lewis is consistent. sewer lateral collapse during atmospheric river rainfall events drives most of the emergency restoration calls we get. A close second is hillside septic system failure during saturated soil conditions.
Fort Lewis experiences mild, wet winters with frequent rainfall, increasing the risk of sewer and septic system failures. The region's proximity to the Puget Sound also contributes to high moisture levels, accelerating bacterial growth in contaminated water.

The region's proximity to the Puget Sound also contributes to high moisture levels, accelerating bacterial growth in contaminated water. The dominant local driver is sewer lateral collapse during atmospheric river rainfall events, with hillside septic system failure during saturated soil conditions showing up as the next most common cause. Damage builds in stages. Spread. Absorption. Microbial growth. Structural compromise. Every stage you pass through adds to the final bill.
