Housing Age Profile

Since 1986, federal law has prohibited lead solder in new residential plumbing. With a median build year of 2000, much of Tiffin's housing falls on the safer side of that line - though homes built before 1986 still warrant testing regardless of the city-wide profile.

Tiffin: Lead Risk & Vulnerable Populations

10%
Homes Built Before 1986

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.

10% - that captures the slice of Tiffin 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.

A/V Share of Claim-Record ZIPs

Historical NFIP data for Tiffin contains 3 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $13,269. 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.
