Housing & Infrastructure in Colleyville
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
Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 1997 places Colleyville in the middle zone between those thresholds - with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.
Most homes in Colleyville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Colleyville Homeowners
In Colleyville, documented water and safety issues can be addressed without making a meaningful dent in home equity - the financial proportionality here is favorable, and the commitment fits within standard property planning frameworks.
Remediation costs in Colleyville are relatively low compared to home values. The $1,200–$2,600 estimated range is a small fraction of median property value. Home values are 214% above the Texas average.
Lead Exposure Risk for Children in Colleyville
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.
If 33% of the Colleyville inventory comes from before the federal ban on lead-bearing solder - and if utility samples sit at or near 0.015 mg/L - the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

Historical NFIP Claim Context in Colleyville
Historical NFIP data for Colleyville contains 63 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $20,126. Among ZIP codes with claim records, 0% 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 <strong>$1,800</strong> 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.
