Grizzly Flats 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
With a median build year of 1997, Grizzly Flats's housing stock reflects a city built across multiple eras. A substantial share of homes predate 1986 - the year lead solder in plumbing was federally banned - meaning the risk from plumbing materials is unevenly distributed across the city's neighborhoods and property types.
Most homes in Grizzly Flats were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Grizzly Flats
In Grizzly Flats, the equity impact of remediation is proportionally small - not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.
Remediation costs in Grizzly Flats are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 50% below the California average.
Grizzly Flats: 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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted - but 35% of the Grizzly Flats inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.
