How Old Is Mission'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
Banned from residential plumbing in 1986, lead solder was a near-universal feature of copper plumbing before that cutoff. In Mission, where the median build year is 1997, the majority of housing falls into the post-ban category — though the older fraction of the stock still carries the residual risk that comes with pre-1986 pipe and solder materials.
Most homes in Mission were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Mission: Remediation Cost in Perspective
Property values and remediation costs in Mission combine to produce a high equity share — the financial burden here is significant.
At 2.2% of home value, remediation costs in Mission represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,750–$3,900. Home values here are 47% below the Texas average.
Protecting Children from Lead in Mission
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.
21% — that captures the slice of Mission stock built before federal rules removed lead-bearing solder from new construction. Combined with system samples below the regulatory action mark, the picture points to a quiet baseline, with one-home draws as the only direct read on a specific address.

Climate-Related Water Risk for Mission
Measured against the full NFIP dataset, Mission's flood record stands out: 627 claims accumulated over decades and 100% of ZIP codes inside FEMA-designated boundaries add up to a high-exposure profile where water infrastructure has faced recurrent stress.
Mission has a significant flood history with 627 FEMA flood insurance claims on record, averaging $23,954 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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.
