How Old Is Hillsboro's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Check your utility's service line inventory as well as your home's build year; in Hillsboro, where the median build year is 1997, both pieces help.
Most homes in Hillsboro were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Protecting Children from Lead in Hillsboro
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
A tap test is worth considering in Hillsboro, where area lead results average at least 10 parts per billion and 40% of homes are older than 1986.

Historical Flood-Claim Evidence for Hillsboro
Historical NFIP data for Hillsboro contains 184 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $15,612. 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 $800 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.
