Housing & Infrastructure in Selbyville
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
Selbyville's housing stock skews relatively recent, with a median build year of 2007. Homes constructed after 1986 avoid the lead-soldered copper joints that were standard before the federal ban — reducing aggregate risk from plumbing as a contamination pathway.
Most homes in Selbyville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Selbyville Homeowners
Low proportionality — that's the Selbyville picture when remediation costs are placed against typical home equity.
Remediation costs in Selbyville are relatively low compared to home values. The $1,200–$2,600 estimated range is a small fraction of median property value. Home values are 22% above the Delaware average.
Lead Exposure Risk for Children in Selbyville
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.
Even with citywide samples reading clean and just 22% of Selbyville homes dating to the pre-rule era, individual-faucet conditions remain a separate question that aggregate utility data cannot resolve for one specific address. That gap is structural, not a function of severity.

Flood & Climate Risk in Selbyville
Flood activity in Selbyville is neither negligible nor at the level of the highest-exposure areas in the NFIP dataset. The 376-claim record and 100% flood zone coverage suggest a community that has experienced recurrent events but has not faced the kind of sustained, severe exposure where water-supply contamination becomes a primary public health concern. It sits in a middle range where flood history merits inclusion in any complete local water quality picture.
Selbyville has a moderate flood history with 376 FEMA claims averaging $11,507 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>$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.
