Skokie Infrastructure Age
With 88% 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
Pre-1986 plumbing is not a rare legacy case in Skokie — it's the dominant profile. The median build year of 1951 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Skokie were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Remediation costs in Skokie are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 107% above the Illinois average.
Skokie: Lead Risk & Vulnerable Populations
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 Skokie have approached or crossed the regulatory action level on multiple occasions. Combined with 88% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

Skokie: Flood History & Water Damage Risk
Across the NFIP's long tracking period, Skokie shows 334 claims and 100% of ZIP codes within FEMA-designated flood zones — figures that place it in moderate flood exposure territory. At this level, the water-quality implications of flooding — contaminated wells, stressed treatment intake, distribution backflow — move from theoretical edge cases to genuine periodic risks, particularly during higher-severity events.
Skokie has a moderate flood history with 334 FEMA claims averaging $4,546 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>$1,600</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.
