Housing Age Profile
Homes on the same street in Leawood can differ: one may keep original pre-1986 plumbing while another has been replumbed, so the 1981 median is only a starting point.
Most homes in Leawood were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Leawood Homeowners
Because the median home value in Leawood is large relative to the estimated cost of remediation, the ratio between them stays at or below 1%; that is a statement about two area-level numbers, not a quote for a particular house or a judgment about what an owner can pay.
Estimated remediation costs in Leawood can be compared with local home values. The $300–$800 estimated range can be set against the median property value; actual costs vary by home. Home values are 288% above the Kansas average.
Lead Exposure Risk for Children in Leawood
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Historical NFIP Claim Context in Leawood
Historical NFIP data for Leawood contains 136 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $29,988. Among ZIP codes with claim records, 33% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The $500 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
