How Old Is Tolley'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
Lead solder was a standard plumbing material before 1986, when federal law prohibited its use in new residential construction. In Tolley, the median build year of 2004 indicates that plumbing age is a material factor in local lead risk - with the pre-1986 share concentrated in specific neighborhoods and building types where older construction remains common.
A significant portion of Tolley's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Protecting Children from Lead in Tolley
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.
Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 40% of Tolley stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.

Historical Flood-Claim Evidence for Tolley
Historical NFIP data for Tolley contains 9 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $11,595. 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>$2,400</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.
