What affects the cost in Aurora
Climate: ERA5 reanalysis via Open-Meteo
USDA soil maps put Fondis soils across much of Aurora, with 8 of the 17 rated sample points in slow-shedding hydrologic groups. Drainage is genuinely mixed across the city, and roughly 124 freeze-thaw cycles a year work at any crack that lets it in. Soil varies sharply across Aurora, so treat this as the pattern across 17 sampled points rather than a description of your lot.
Soil: USDA NRCS SSURGO · Fondis silt loam, 1 to 3 percent slopes · 17 points sampled
Permits in Aurora

What puts water in an Aurora basement
Aurora goes through about 124 freeze-thaw cycles in an average year (ERA5 reanalysis). Each cycle expands the water in saturated soil against foundation walls, and repeated over a winter that frost pressure works cracks open and lets seepage in.
And it is not only a floodplain problem: in Arapahoe County, about 91% of basement flood-insurance claims were filed outside the mapped flood zone, and because flood insurance is mostly bought only inside that zone, the real outside-the-zone share is almost certainly higher.

Aurorabasement & foundation FAQ
Why do basements take on water in Aurora?+

My home isn't in a flood zone, can the basement still flood in Aurora?+
Yes. In Arapahoe County, about 91% of basement flood-insurance claims were filed outside the mapped flood zone, and because flood insurance is mostly bought only inside the zone, the true out-of-zone share is almost certainly higher. Basement water is usually a groundwater problem, which the flood map does not measure.
