Housing & Infrastructure in Harrison
With 81% 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
Heavily weighted toward older construction, Harrison's housing stock carries a median build year of 1969. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Harrison 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 Harrison Homeowners
Because property values in Harrison comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Harrison are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 158% above the New York average.
Lead Exposure Risk for Children in Harrison
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 Harrison, where 81% 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 Harrison
FEMA data places 100% of Harrison's ZIP codes inside designated flood zones, and the NFIP claim record confirms the real-world impact: 856 filed claims representing decades of documented flood events with consequences for property and, at sufficient severity, for local water infrastructure.
Harrison has a significant flood history with 856 FEMA flood insurance claims on record, averaging $13,063 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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>$1,200</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.
