Housing & Infrastructure in Seaside Park
With 78% 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
What does a median build year of 1951 mean for water safety in Seaside Park? 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 Seaside Park 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 Seaside Park Homeowners
Property equity in Seaside Park runs well ahead of estimated remediation costs — a cost-to-value ratio that sits in the low tier, meaning documented water and safety issues here are the kind homeowners can plan to address without treating the expense as a significant budget event relative to what their homes are worth.
Remediation costs in Seaside Park are relatively low compared to home values. The $1,200–$2,500 estimated range is a small fraction of median property value. Home values are 61% above the New Jersey average.
Lead Exposure Risk for Children in Seaside Park
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 78% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Seaside Park.

Flood & Climate Risk in Seaside Park
Because Seaside Park's NFIP claim count reaches 1441 and 100% of ZIP codes fall within FEMA-designated flood zones, flood exposure here operates differently than it does in lower-claim communities. In areas with isolated flood events, water-quality infrastructure can typically absorb the stress and recover between events. In communities with repeated high-volume flooding, treatment plants face recurring overload conditions, private wells in FEMA-designated zones accumulate repeated infiltration episodes, and distribution systems experience repeated pressure events that can drive backflow. The claim record for this area points to that second category: a flood environment where water infrastructure stress is periodic and documented, not theoretical.
Seaside Park has a significant flood history with 1,441 FEMA flood insurance claims on record, averaging $33,084 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>$1,800</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.
