How Old Is Flower Mound'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
Lead exposure in tap water isn't just a function of what water utilities deliver — it's also shaped by the plumbing inside individual homes. Structures built before 1986 may contain lead-soldered copper joints, and homes built before 1970 face an additional risk from lead pipes themselves. Flower Mound's median build year of 1993 suggests the housing stock is broadly weighted toward the safer post-1986 era, but the age distribution shown above makes clear that the pre-1986 share of the inventory still represents a meaningful fraction worth understanding for anyone in an older home.
Most homes in Flower Mound were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Flower Mound: Remediation Cost in Perspective
In Flower Mound, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Flower Mound are relatively low compared to home values. The $1,083–$2,567 estimated range is a small fraction of median property value. Home values are 171% above the Texas average.
Protecting Children from Lead in Flower Mound
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.
Aggregate sampling rests beneath the federal action threshold here, while only 16% of Flower Mound housing predates the solder rule change.

Climate-Related Water Risk for Flower Mound
Although Flower Mound's flood history doesn't reach high-severity thresholds, NFIP data documents 49 claims and FEMA maps place 67% of ZIP codes in designated flood zones — a combined profile that makes flood-related water quality considerations a reasonable planning baseline.
Flower Mound has a moderate flood history with 49 FEMA claims averaging $19,578 per payout. 67% 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.
