Housing & Infrastructure in Terrell
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
Reading the housing data for Terrell, with a median build year of 1990, reveals a community where neither old nor new construction dominates. That balanced profile means lead-solder-era plumbing is present throughout a meaningful portion of the residential inventory — with risk concentrated in properties built before 1986 and most acute in those that predate 1970.
Most homes in Terrell were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Terrell Homeowners
When remediation costs are measured against Terrell home values, the resulting ratio is in the low tier — addressing documented water and safety issues here claims only a minor fraction of typical equity, and most homeowners are in a position where the financial commitment is straightforward rather than a material burden on their household budget.
Remediation costs in Terrell are relatively low compared to home values. The $1,400–$2,950 estimated range is a small fraction of median property value. Home values are 2% below the Texas average.
Lead Exposure Risk for Children in Terrell
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.
Locally, 40% of Terrell homes carry interior plumbing from the era when lead solder was still permitted in new builds, and citywide monitoring approaches or crosses the EPA action benchmark. Households can find a draw-test kit and certified filtration through verified retailers.

Flood & Climate Risk in Terrell
Although Terrell's flood history doesn't reach high-severity thresholds, NFIP data documents 24 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.
Terrell has a moderate flood history with 24 FEMA claims averaging $18,079 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>$2,100</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.
