How Old Is Evansdale's Housing Stock?
With 72% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Evansdale's median build year of 1968 places it squarely in that category.
Over half of homes in Evansdale were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Evansdale: Remediation Cost in Perspective
Given current Evansdale property values, the remediation-to-equity ratio falls in the elevated tier - deliberate financial planning is a meaningful factor in how homeowners approach the documented water and safety issues on record here.
At 2.1% of home value, remediation costs in Evansdale represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $2,000–$4,100. Home values here are 13% below the Iowa average.
Protecting Children from Lead in Evansdale
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.
Routinely in Evansdale, where 72% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.

Historical Flood-Claim Evidence for Evansdale
Historical NFIP data for Evansdale contains 43 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $7,618. 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>$3,000</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.
