Housing & Infrastructure in Jamestown
With 68% 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 Jamestown — it's the dominant profile. The median build year of 1974 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Jamestown 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 Jamestown Homeowners
The household financial picture for Jamestown homeowners is proportionally favorable — addressing documented issues claims a small slice of equity, and the cost-to-value ratio puts this area well within the manageable tier.
Remediation costs in Jamestown are relatively low compared to home values. The $1,100–$3,400 estimated range is a small fraction of median property value. Home values are 83% above the Rhode Island average.
Lead Exposure Risk for Children in Jamestown
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 Jamestown have approached or crossed the regulatory action level on multiple occasions. Combined with 68% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

Flood & Climate Risk in Jamestown
How does Jamestown's flood record connect to local water quality? The NFIP documents 58 claims — enough to signal recurring events — and 100% of ZIP codes carry FEMA flood zone status. That combination places flooding in the category of factors that can periodically affect water infrastructure, even if the area isn't among the highest-exposure communities in the NFIP dataset.
Jamestown has a moderate flood history with 58 FEMA claims averaging $4,999 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>$2,100</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.
