Housing Age Profile
What does a median build year of 1966 mean for water safety in Bay Shore? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used - making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Bay Shore 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 Bay Shore Homeowners
Low proportionality - that's the Bay Shore picture when remediation costs are placed against typical home equity.
Remediation costs in Bay Shore are relatively low compared to home values. The $1,600–$3,300 estimated range is a small fraction of median property value. Home values are 28% above the New York average.
Lead Exposure Risk for Children in Bay Shore
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 80% of the Bay Shore inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.

Historical NFIP Claim Context in Bay Shore
Historical NFIP data for Bay Shore contains 2,052 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $47,061. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The <strong>$2,400</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
