How Old Is Bulverde'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
A post-1986 majority in Bulverde's housing inventory — median build year 1990 — generally signals lower aggregate plumbing-era lead risk.
Most homes in Bulverde were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Bulverde: Remediation Cost in Perspective
Across Bulverde, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.

Protecting Children from Lead in Bulverde
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.
In Bulverde, the older-stock footprint runs at 17% — a contained slice — and aggregate utility readings land safely under the EPA action mark. That keeps lead off the local priority list, with a one-faucet draw remaining the only direct read on a specific address.

Climate-Related Water Risk for Bulverde
Within the NFIP's national dataset, Bulverde falls in moderate-exposure territory — 118 documented incidents spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Bulverde has a moderate flood history with 118 FEMA claims averaging $38,566 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>$2,700</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.
