Inside city limits the ground ranges from about 324 to 1,029 feet above sea level (USGS 3DEP). Terrain flow lines are not a record of past flooding at a house or a prediction of stormwater depth. Choose a location to see surface drainage analysis and water flow direction based on terrain shape. The first three locations are free.

How to read this. These are National Flood Insurance Program claims, so they count only insured buildings and miss flooding where owners had no flood insurance. FEMA publishes them without names or addresses: they show which years and areas flooded, never whether a particular house did. They are the claims rated in the city’s own NFIP community, which covers the city limits. ZIP codes are as reported on the claims, and a ZIP code can extend beyond the city. The “rated” flood zone is the one used to price the policy and may come from an older map. Data as of 2026-09-08, from FEMA OpenFEMA.
