How Old Is Hales Corners's Housing Stock?

Housing Age Profile
Heavily weighted toward older construction, Hales Corners's housing stock carries a median build year of 1966. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Hales Corners were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Hales Corners: Remediation Cost in Perspective
Across Hales Corners, the equity share taken up by estimated remediation is small - a favorable ratio for most property owners.

Protecting Children from Lead in Hales Corners
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted - but 81% of the Hales Corners inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.

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.
