How Old Is Wilsonville'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
Although a small portion of Wilsonville's homes predate 1986, the median build year of 1993 indicates the majority of the city's residential plumbing was installed after lead solder was banned - which tends to reduce the plumbing-related component of lead exposure at the household level.
Most homes in Wilsonville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Wilsonville: Remediation Cost in Perspective
At current valuations, Wilsonville sits in the low remediation-share tier - the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Wilsonville are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 48% above the Oregon average.
Protecting Children from Lead in Wilsonville
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.
Whenever aggregate samples pass the federal action benchmark and pre-rule housing - 25% in Wilsonville - represents a smaller fraction, lead occupies a lower priority on the local picture.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies.
