Housing & Infrastructure in Troy
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
Cities with large shares of pre-1986 housing carry elevated aggregate risk from lead-soldered plumbing; Troy sits on the lower end of that spectrum. The median build year of 1993 reflects a housing stock in which post-ban construction is dominant - meaning lead-soldered copper joints are less prevalent across the city as a whole. Still, aggregate figures don't tell you what's happening inside a specific older home. Any structure built before 1986, and particularly those built before 1970 when lead pipes were commonly installed, can still present meaningful lead risk regardless of the city-wide picture.
Most homes in Troy were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Troy Homeowners
Remediation costs in Troy are small relative to typical property values - the cost-to-value ratio here is favorable.
Remediation costs in Troy are relatively low compared to home values. The $950–$3,200 estimated range is a small fraction of median property value. Home values are 36% above the Missouri average.
Lead Exposure Risk for Children in Troy
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.
Through the multi-year window of EPA Lead and Copper Rule monitoring, Troy has stayed under the action mark. Paired with a 29% pre-rule housing share, the result places lead in a lower-priority spot on the local picture - without erasing the structural gap between citywide averages and what arrives at one specific tap.

Historical NFIP Claim Context in Troy
Historical NFIP data for Troy contains 82 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $16,110. Among ZIP codes with claim records, 100% 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>$1,900</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.
