How Old Is Wylie's Housing Stock?
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
Banned from residential plumbing in 1986, lead solder was a near-universal feature of copper plumbing before that cutoff. In Wylie, where the median build year is 2004, the majority of housing falls into the post-ban category — though the older fraction of the stock still carries the residual risk that comes with pre-1986 pipe and solder materials.
Most homes in Wylie were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Wylie: Remediation Cost in Perspective
Setting Wylie remediation figures against its property market, the resulting ratio sits comfortably in the low tier — a classification that reflects the kind of household financial position where most homeowners can identify documented issues, schedule the work, and absorb the cost without it registering as a significant budget disruption.
Remediation costs in Wylie are relatively low compared to home values. The $1,100–$2,600 estimated range is a small fraction of median property value. Home values are 59% above the Texas average.
Protecting Children from Lead in Wylie
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.
Despite citywide averages reading cleanly under the federal action threshold, the way utilities pull samples — from a representative subset rather than door-to-door — leaves room for individual buildings with older interior lines to behave differently than the aggregate suggests. With only 16% of Wylie stock predating the solder rule, that residual subset is small but real, and a draw-test kit gives the only direct read on what comes out of one faucet on a given morning.

Climate-Related Water Risk for Wylie
Although Wylie's flood history doesn't reach high-severity thresholds, NFIP data documents 23 claims and FEMA maps place 100% of ZIP codes in designated flood zones — a combined profile that makes flood-related water quality considerations a reasonable planning baseline.
Wylie has a moderate flood history with 23 FEMA claims averaging $18,532 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>$1,700</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.
