Wimberley Infrastructure Age
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
Tap water lead levels are shaped by two factors: what the utility delivers, and what the household plumbing adds to it. Older homes contribute disproportionately to that second variable because lead solder was standard in copper plumbing before 1986, and lead pipes were common before 1970. In Wimberley, where the median build year is 1991, a substantial share of the housing stock falls into these older categories. The bar chart above breaks out the pre-1970, 1970-to-1986, and post-1986 segments — the key ages for understanding where plumbing-era risk concentrates across the city.
Most homes in Wimberley were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Wimberley
Remediation costs in Wimberley are small relative to typical property values — the cost-to-value ratio here is favorable.
Remediation costs in Wimberley are relatively low compared to home values. The $1,950–$4,600 estimated range is a small fraction of median property value. Home values are 109% above the Texas average.
Wimberley: Lead Risk & Vulnerable Populations
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 31% of the Wimberley inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Wimberley: Flood History & Water Damage Risk
Flood exposure in Wimberley is meaningful by NFIP measures — 472 claims on record and 100% of ZIP codes carrying FEMA flood zone designations. That level of activity makes flood history a relevant factor when evaluating local water quality over time.
Wimberley has a moderate flood history with 472 FEMA claims averaging $79,623 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>$2,800</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.
