Tracy Infrastructure Age
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
Post-1986 construction is where the lower lead-solder risk lives, because that's when the federal ban on lead solder in plumbing took effect. In Tracy, where the median build year is 1996, the housing stock falls broadly on the newer side of that threshold - a distribution that moderates aggregate plumbing-era risk compared to older housing markets.
Most homes in Tracy were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Tracy
Across Tracy, the equity share taken up by estimated remediation is small - a favorable ratio for most property owners.
Remediation costs in Tracy are relatively low compared to home values. The $790–$1,960 estimated range is a small fraction of median property value. Home values are 16% above the California average.
Tracy: Lead Risk & Vulnerable Populations
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.
Since the federal solder ban took effect, new plumbing has been built without that pathway, and Tracy's pre-rule stock at 27% reflects a contained footprint.

Tracy: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Tracy contains 67 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $31,696. 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 <strong>$1,260</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.
