Benicia Infrastructure Age
With 68% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Plumbing risk in older housing is defined by two eras: the pre-1970 period when lead pipes were commonly used for service lines, and the 1970-to-1986 period when lead solder remained standard in copper plumbing until the federal ban. Benicia's median build year of 1988 lands in a range where both eras are heavily represented in the housing stock. That creates an elevated aggregate environment for plumbing-related lead exposure - one that city-level water quality averages don't capture, because the risk sits inside individual properties rather than in the distribution system.
Over half of homes in Benicia were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Benicia
Equity impact data for Benicia lands in the favorable tier - remediation claims a small slice of what properties here are worth.
Remediation costs in Benicia are relatively low compared to home values. The $2,100–$4,800 estimated range is a small fraction of median property value. Home values are 5% above the California average.
Benicia: 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.
Older interior plumbing shapes the local picture: 68% of Benicia homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.

Benicia: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Benicia contains 21 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $63,139. 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>$3,000</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.
