Housing & Infrastructure in Stone Harbor
With 61% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
The median home in Stone Harbor was built in 1974 — a figure that places most of the city's residential stock in the era when lead solder was still standard in copper plumbing. Homes built before 1986 may have lead-soldered joints; those built before 1970 face the additional possibility of lead pipes in the service line itself.
Over half of homes in Stone Harbor 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 Stone Harbor Homeowners
For most homeowners in Stone Harbor, the estimated cost of water and safety remediation represents a proportionally modest share of what properties are worth — placing this area in the lower tier of the remediation share scale.
Remediation costs in Stone Harbor are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 267% above the New Jersey average.
Lead Exposure Risk for Children in Stone Harbor
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.
61% — that captures the slice of Stone Harbor housing dating from before the federal ban on solder containing lead. It pairs with aggregate utility readings that either approach or cross 0.015 mg/L, the benchmark set under the EPA Lead and Copper Rule. Together, the two figures shift one-home reads into a standard household-level confirmation, particularly for families with kids. A certified lead-removal filter is available through retailer-verified channels if a kit returns results that warrant additional measures.

Flood & Climate Risk in Stone Harbor
Stone Harbor's flood profile — 1539 NFIP claims over the program's multi-decade period and 100% of ZIP codes within FEMA-designated flood zones — reflects a community where flooding has shaped the local risk landscape in sustained ways. That sustained exposure has specific consequences for water quality that don't apply to lower-exposure areas. Treatment facilities handling intake from flood-saturated watersheds face contaminant loads that can exceed normal filtration capacity. Private wells in FEMA-designated zones face surface infiltration risk during every significant event. Distribution systems in areas that flood repeatedly accumulate backflow stress over time. None of these represent constant threats to water quality, but they are activated by the kinds of events that the NFIP record shows have occurred here, repeatedly, over many years.
Stone Harbor has a significant flood history with 1,539 FEMA flood insurance claims on record, averaging $14,286 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.
