Housing Age Profile
Over the decades, West Des Moines accumulated housing from multiple construction periods. The median build year of 1997 places the midpoint of that stock near the 1986 threshold when lead solder in plumbing became federally prohibited - leaving a sizable share of homes on each side of that safety line.
Most homes in West Des Moines were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in West Des Moines
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If 41% of the West Des Moines inventory comes from before the federal ban on lead-bearing solder - and if utility samples sit at or near 0.015 mg/L - the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

Historical Flood-Claim Evidence for West Des Moines
Historical NFIP data for West Des Moines contains 416 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $13,060. Among ZIP codes with claim records, 100% 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 <strong>$2,400</strong> 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.
