Housing & Infrastructure in Schertz
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Copper plumbing joined with lead solder was standard practice through the mid-1980s — a design choice that federal regulators prohibited in 1986. Schertz's residential inventory, centered around a median build year of 2007, is weighted toward the post-prohibition era. That context is relevant because the primary plumbing risk in older homes comes not from the municipal water supply but from what happens as water moves through lead-jointed pipes inside the structure — an exposure pathway that newer homes mostly avoid.
Most homes in Schertz were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Schertz Homeowners
At current valuations, Schertz sits in the low remediation-share tier — the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Schertz 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 30% above the Texas average.
Lead Exposure Risk for Children in Schertz
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.
Since the federal solder ban took effect, new plumbing has been built without that pathway, and Schertz's pre-rule stock at 19% reflects a contained footprint.

Flood & Climate Risk in Schertz
The NFIP claim record for Schertz — 68 filed incidents — reflects genuine, recurring flood exposure rather than an isolated event or two. When a community accumulates flood claims at this volume and carries 100% of its ZIP codes inside FEMA-designated zones, flood history starts to factor into water quality planning in ways it doesn't for lower-exposure areas. Flooding introduces specific contamination pathways — runoff overwhelming treatment facility intake, surface water infiltrating private wells, and pressure disruptions in distribution systems allowing backflow — all of which become more relevant as flood frequency increases.
Schertz has a moderate flood history with 68 FEMA claims averaging $16,421 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.
