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
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Wilsonville, the median build year of 1992 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
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
Given current Wilsonville valuations, the remediation-to-property-value ratio is low — most homeowners are looking at a proportionally modest share that fits within routine financial planning.
Remediation costs in Wilsonville are relatively low compared to home values. The $1,200–$3,400 estimated range is a small fraction of median property value. Home values are 76% above the Alabama 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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 31% pre-rule share in Wilsonville keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Climate-Related Water Risk for Wilsonville
Over the multi-decade window covered by the National Flood Insurance Program, Wilsonville has accumulated 8 claims — a total that suggests more than isolated flood exposure. With 100% of ZIP codes in designated flood zones, the water-quality implications of flooding move from hypothetical to periodically relevant: treatment intake can be compromised, wells can be infiltrated, and distribution backflow can occur.
Wilsonville has a moderate flood history with 8 FEMA claims averaging $6,031 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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. Flood damage can add significantly to the estimated <strong>$2,200</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
