Housing & Infrastructure in Arena
With 50% 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 Arena — it's the dominant profile. The median build year of 1983 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Arena were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Arena Homeowners
The cost-to-value ratio in Arena is in the moderate range — neither dismissible nor alarming, but above the threshold where remediation can be treated as incidental. Most homeowners here are weighing a real equity commitment, and the moderate classification reflects that accurately.
Remediation costs are moderate relative to home values in Arena. The estimated $2,000–$4,000 range is manageable for most homeowners but still worth budgeting for. Home values are 0% above the Wisconsin average.
Lead Exposure Risk for Children in Arena
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.
Older interior plumbing shapes the local picture: 50% of Arena homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.

Flood & Climate Risk in Arena

Arena has a moderate flood history with 4 FEMA claims. 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>$3,000</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.
