Housing Age Profile
What does a median build year of 1956 mean for water safety in Allison? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used - making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Allison were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Allison
What should Allison property owners understand before approaching remediation at this cost-to-value tier? That the equity share is elevated enough to treat this as a formal financial decision - one where knowing the full scope and prioritizing documented issues by urgency shape the outcome more than any single variable, given where this market falls on the remediation-share scale.
At 2.3% of home value, remediation costs in Allison represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,600–$3,300. Home values here are 37% below the Iowa average.
Allison: Lead Risk & Vulnerable Populations
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.
Practically, the structural drivers in Allison - 79% pre-rule stock and citywide monitoring at or beyond the regulatory benchmark - make an in-home draw the practical way to translate aggregate averages into the specific conditions at one address.

Allison: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Allison contains 1 flood insurance claim. Among claims with payment data, the average reported building, contents, and ICC component sum is $6,233. 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.
