How Old Is Haiku's Housing Stock?
With 44% 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 trying to understand water quality at the household level, the year a home was built often matters more than any city-wide water report. That's because the 1986 federal ban on lead solder in plumbing, and the earlier phase-out of lead pipes before 1970, created sharp discontinuities in residential plumbing risk by construction era. Haiku's median build year of 1981 puts the city in the transition zone: a substantial share of the housing stock postdates the solder ban, but a comparable fraction predates it - with the oldest homes carrying both the solder risk and the pipe risk simultaneously. Whether any individual household sits on the safer or riskier side of these thresholds is the key question, and it's one the city-wide median alone can't answer.
Most homes in Haiku were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Haiku: Remediation Cost in Perspective
What does remediation cost in financial context for Haiku homeowners? Proportionally very little - the equity share here is low, and addressing documented issues is a manageable planning question rather than a material financial burden.
Remediation costs in Haiku are relatively low compared to home values. The $2,560–$5,320 estimated range is a small fraction of median property value. Home values are 42% above the Hawaii average.
Protecting Children from Lead in Haiku
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Haiku have approached or crossed the regulatory action level on multiple occasions. Combined with 44% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

Historical Flood-Claim Evidence for Haiku
Historical NFIP data for Haiku contains 9 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $2,077. 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>$3,840</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.
