Durham sits in the NC Piedmont, home to Duke University and a growing Research Triangle tech economy. Ellerbe Creek and Eno River create moderate flood corridors through the city. Durham receives 47 inches of rain annually with significant hurricane remnant events (Florence 2018, Floyd 1999 caused major flooding regionally). The city's building boom from tech and university growth creates mixed-age housing stock from aging tobacco warehouse conversions to modern construction. High-humidity Piedmont climate means water damage events progress rapidly to mold if not addressed within 48 hours.
Flood-prone areas: Northgate Park and Morehead Hill near Ellerbe Creek have highest flood risk. Hope Valley and Southpoint are newer with modern drainage. Duke Park and Watts-Hillandale have older homes with higher plumbing failure rates.
