The region's topography also contributes to localized flooding and sewer lateral damage during heavy rainfall. 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.
