Mountain View Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Lead solder was a standard plumbing material before 1986, when federal law prohibited its use in new residential construction. In Mountain View, the median build year of 1995 indicates that plumbing age is a material factor in local lead risk — with the pre-1986 share concentrated in specific neighborhoods and building types where older construction remains common.
Most homes in Mountain View were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Mountain View
Across Mountain View, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.
Remediation costs in Mountain View are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 60% below the Hawaii average.
Mountain View: 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: 32% of Mountain View 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.

Mountain View: Flood History & Water Damage Risk
100% of ZIP codes in Mountain View are mapped into FEMA-designated flood zones, and the NFIP records 2 claims reflecting a multi-event flood history. That combination places local flood exposure in the range where water-quality implications deserve at least periodic attention.
Mountain View has a moderate flood history with 2 FEMA claims averaging $13,823 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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. Flood damage can add significantly to the estimated <strong>$1,200</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
