Housing & Infrastructure in Magnolia
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
Construction dates in Magnolia center on a median of 2006, and the Census figures behind it describe when homes were built, not what materials they contain.
Most homes in Magnolia were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Magnolia Homeowners
In Magnolia, estimated remediation comes to 1% or less of the median home value.
Estimated remediation costs in Magnolia can be compared with local home values. The $300–$1,500 estimated range can be set against the median property value; actual costs vary by home. Home values are 66% above the Texas average.
Lead Exposure Risk for Children in Magnolia
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
For families with young children in Magnolia, two area figures are available: pre-1986 construction at about 17%, and a mean of the ZIP codes' 90th-percentile lead results under 0.010 mg/L. Testing water from the tap a child drinks from gives a home-specific result.
Sources: EPA Lead and Copper Rule, U.S. Census Bureau ACS, CDC childhood lead poisoning prevention guidelines.
Historical NFIP Claim Context in Magnolia
Historical NFIP data for Magnolia contains 996 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $68,085. Among ZIP codes with claim records, 33% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The $600 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
