Housing & Infrastructure in Smithville
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
With a median build year of 1995, Smithville's housing stock reflects a city built across multiple eras. A substantial share of homes predate 1986 — the year lead solder in plumbing was federally banned — meaning the risk from plumbing materials is unevenly distributed across the city's neighborhoods and property types.
Most homes in Smithville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Smithville Homeowners
Because property values in Smithville comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Smithville are relatively low compared to home values. The $1,900–$4,100 estimated range is a small fraction of median property value. Home values are 75% above the Missouri average.
Lead Exposure Risk for Children in Smithville
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 Smithville, where 33% 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.

Flood & Climate Risk in Smithville
Over the multi-decade window covered by the National Flood Insurance Program, Smithville has accumulated 92 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.
Smithville has a moderate flood history with 92 FEMA claims averaging $6,561 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>$2,900</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.
