Housing Age Profile

Housing age is one of the most reliable proxies for plumbing-era lead risk, because two federal milestones - the widespread use of lead pipes before 1970 and the continued use of lead solder until 1986 - define the highest-risk tiers of the residential housing stock. With a median build year of 1987, Beaverton falls squarely within the older range - meaning a large fraction of the housing was built under the plumbing standards of those earlier eras. The distribution above captures where that risk concentrates, and why older neighborhoods warrant particular attention from residents concerned about tap water quality.

Pre-1970 (Lead Pipes Risk)

Pre-1970 (8%) 1970–1986 (42%) Post-1986 (50%)

Over half of homes in Beaverton were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Beaverton Homeowners

While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Beaverton is notably favorable - the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.

Median Home Value

$535,800

Est. Remediation

$1,150

Remediation as % of home value 0.2%

Remediation costs in Beaverton are relatively low compared to home values. The $500–$1,925 estimated range is a small fraction of median property value. Home values are 32% above the Oregon average.

Lead Exposure Risk for Children in Beaverton

50%

Homes Built Before 1986

0.0047

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.

Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 50% of Beaverton stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.

40%

A/V Share of Claim-Record ZIPs

Historical NFIP data for Beaverton contains 118 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $11,184. Among ZIP codes with claim records, 40% 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>$1,150</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.
