Portland sits at the confluence of the Willamette and Columbia Rivers. This geographic position makes riverine flooding and groundwater intrusion common issues. Neighborhoods near the Willamette like Johns Landing, South Waterfront, and Sellwood experience basement seepage and crawl space flooding during heavy rain cycles. Portland's wet season runs from October through May, delivering the bulk of annual rainfall. When storm systems stall over the Coast Range, rainfall totals can exceed three inches in 24 hours. This saturates the ground and overwhelms drainage systems. Emergency water removal becomes critical for properties in flood-prone areas, older homes with inadequate foundation drainage, and commercial buildings with below-grade spaces.
Portland enforces specific building codes related to water intrusion and moisture control. Homes built after 2014 must meet updated energy efficiency standards that include improved moisture barriers and ventilation. However, most of Portland's housing stock predates these codes. Older homes require experienced technicians who understand how to dry structures without modern vapor barriers or mechanicals.
