Water damage in Montesano tends to cluster in predictable windows because of the local climate. sewer lateral collapse during atmospheric river rainfall events A close second is hillside septic system failure during saturated soil conditions.
Montesano experiences mild, wet winters with frequent rainfall, increasing the risk of sewer and septic system failures. The combination of heavy precipitation and aging infrastructure heightens the likelihood of black water contamination.
