How Old Is Monmouth's Housing Stock?

Likely Pipe Material

With 46% 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.

Housing Age Profile

Some cities skew heavily toward one construction era; Monmouth does not. The median build year of 1999 reflects a housing stock where older and newer homes share the market in meaningful proportions. That mixed profile means the city carries moderate aggregate plumbing-era risk - with older homes, particularly those built before 1986, representing the portion of the stock where lead-soldered joints may still be present.

Pre-1970 (Lead Pipes Risk)
Pre-1970 (11%) 1970–1986 (35%) Post-1986 (54%)

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

Monmouth: Remediation Cost in Perspective

Low proportionality - that's the Monmouth picture when remediation costs are placed against typical home equity.

$407,100
Est. Remediation
$1,200
Remediation as % of home value 0.3%

Remediation costs in Monmouth are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 0% above the Oregon average.

Protecting Children from Lead in Monmouth

46%
Homes Built Before 1986
0.0043
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.

If 46% of the Monmouth inventory comes from before the federal ban on lead-bearing solder - and if utility samples sit at or near 0.015 mg/L - the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

Historical Flood-Claim Evidence for Monmouth

9
Total FEMA Flood Claims
$27,690
Avg Reported Sum With Payment Data
100%
A/V Share of Claim-Record ZIPs

Historical NFIP data for Monmouth contains 9 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $27,690. 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>$1,200</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.
