Housing & Infrastructure in Henderson
With 69% 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, Henderson's housing stock carries a median build year of 1964. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Henderson 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 Henderson Homeowners
Property value and cost data for Henderson produce a moderate remediation-share classification — a level where advance financial planning has real practical value and the commitment is realistic for most homeowners who approach it deliberately.
Remediation costs are moderate relative to home values in Henderson. The estimated $1,100–$4,100 range is manageable for most homeowners but still worth budgeting for. Home values are 43% below the New York average.
Lead Exposure Risk for Children in Henderson
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.
When older housing represents 69% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Henderson address.

Flood & Climate Risk in Henderson
Over the multi-decade window covered by the National Flood Insurance Program, Henderson has accumulated 13 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.
Henderson has a moderate flood history with 13 FEMA claims averaging $9,690 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>$2,200</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.
