Housing Age Profile

A median build year of 2007 in Brentwood points to a housing stock where post-1986 construction is the norm. That matters because lead solder in plumbing - banned federally in 1986 - is a primary pathway by which older homes can elevate tap water lead above what enters the distribution system.

Most homes in Brentwood were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in Brentwood

17%
Homes Built Before 1986
0.0031
mg/L Avg Lead (Limit: 0.015)

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.

Once federal rules removed lead-bearing solder from new plumbing, building practice changed quickly. Brentwood now carries just 17% of older inventory from that earlier era. Citywide readings remain compliant, though no system-level number can replace a one-home draw.

A/V Share of Claim-Record ZIPs

Historical NFIP data for Brentwood contains 11 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $5,030. 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.
