Housing & Infrastructure in Swansboro
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Lead solder was a standard plumbing material before 1986, when federal law prohibited its use in new residential construction. In Swansboro, the median build year of 1992 indicates that plumbing age is a material factor in local lead risk — with the pre-1986 share concentrated in specific neighborhoods and building types where older construction remains common.
Most homes in Swansboro were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Swansboro Homeowners
At current valuations, Swansboro sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Swansboro are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 31% above the North Carolina average.
Lead Exposure Risk for Children in Swansboro
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.
Confirming what flows from a specific faucet still requires a one-home draw, even where Swansboro averages stay clean and the pre-rule housing share holds at 30%.

Flood & Climate Risk in Swansboro
Swansboro carries a substantial flood exposure profile — 817 claims filed over the program's long tracking window and 100% of ZIP codes within FEMA flood zones. For water quality, that exposure level means flooding has likely stressed local treatment and distribution infrastructure on multiple occasions, creating periodic windows of elevated contamination risk.
Swansboro has a significant flood history with 817 FEMA flood insurance claims on record, averaging $17,051 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.
