Boulder is a college city at the Rocky Mountain foothills — the site of Colorado's deadliest modern flood: the September 2013 Front Range flood killed 9 people in Boulder County and caused $2B+ in damage. Boulder Creek and Four Mile Creek created catastrophic flash flooding that overwhelmed every bridge and basement in the flood corridor. CU Boulder's large campus and student housing market creates significant rental maintenance challenges. Boulder is at 5,430 ft elevation with extreme temperature swings. The steep terrain amplifies flash flood speed and intensity — foothills canyon water reaches Boulder in minutes during heavy rain events.
Flood-prone areas: Whittier and University Hill near Boulder Creek have highest flood risk. Mapleton Hill and downtown are in the flood corridor. Table Mesa and south Boulder are higher ground.
