What flood insurance costs in Sangamon County

What NFIP policyholders in Sangamon County pay a year for a single-family home, by flood zone: the middle half of premiums on policies that took effect Sep 2025–Sep 2026. It is what insured homes here pay, not a quote for any one building.

Flood zonePoliciesMiddle halfFull-risk median
A zones (special flood hazard area)69$740–$1,750$1,340
X zone (outside the mapped flood zone)96$440–$830$620

Full-risk premium: the median of FEMA's own full-risk premium for the same policies (Risk Rating 2.0). A discounted policy rises toward it a step each year, within the law's cap on yearly increases. Zones are the flood zone each policy is rated in. OpenFEMA NFIP Redacted Policies v3, as of Sep 2026.

How the rent-to-price figure works

A year’s cash rent for an acre, divided by the median price an acre paid for the same kind of land in this county over the last three years: sales of a single parcel of 10 acres or more, never lots or house sites. Sales counted: Illinois transfer declarations (IDOR PTAX-203) of 10 acres or more that the parties declared as farm property, single-parcel deeds for value with none of the form’s related-party, distress or partial-interest answers checked. Where fewer than 10 such sales were recorded, or their prices range too widely, no figure is shown. A low share usually means land here is priced for something other than farming, such as homes or development.
