Central and west Boulder
80302 covers downtown, University Hill, Chautauqua and the western edge against the foothills. This is the oldest and the most exposed part of the city at once: pre-1940 housing with original or partly updated plumbing, sitting closest to Boulder Creek and to the canyon mouth that feeds it.
Winter pipe bursts concentrate on the Hill, where a large share of the housing is student rental stock that empties over semester break during the coldest weeks of the year. Flood exposure concentrates along the creek corridor and the lower-lying streets near it.
80309 is the University of Colorado campus.
North Boulder
80304 runs north of downtown, taking in the older north Boulder neighborhoods and the newer development beyond them. Housing is mixed — early-century cottages adjacent to 1990s and 2000s infill — so the failure modes are mixed too. Fourmile Canyon Creek and Wonderland Creek both cross this area and both were significant in the 2013 flooding.
East Boulder and Gunbarrel
80301 covers east Boulder and Gunbarrel. Newer construction overall, with modern supply plumbing, more commercial and light-industrial property, and the failure profile that goes with newer buildings: water heaters, appliances and fire sprinkler systems rather than aging pipes. Boulder Creek runs along the southern edge of this area as it leaves town.
South Boulder
80303 and 80305 cover Table Mesa, Martin Acres and the southern neighborhoods against the foothills. Largely 1950s to 1970s construction on sloping ground below the mountain backdrop, which means runoff from above is a real factor during intense rain and rapid snowmelt. Bear Canyon and South Boulder Creek both drain through here.
The 1950s and 1960s housing in Martin Acres and Table Mesa is now at the age where original supply plumbing and original sewer laterals are both failing, which produces a steady baseline of water and sewer calls independent of weather.

Frequently asked questions
Which Boulder ZIP codes are covered?
80301, 80302, 80303, 80304 and 80305 cover the city, with 80309 serving the University of Colorado campus. Surrounding Boulder County communities including Louisville, Superior, Lafayette and Niwot are generally workable depending on contractor availability.
How do I know if I am in the floodplain?
The City of Boulder publishes floodplain mapping, and FEMA's Flood Map Service Center covers the wider county. Being outside a mapped zone is not the same as being safe — plenty of 2013 damage occurred outside mapped areas, because the maps model specific scenarios rather than every possible one.
Does campus housing get covered?
University-owned buildings are handled through the university's own facilities and contracting processes. Privately owned rentals around the Hill and elsewhere in the city are ordinary residential work.
