Housing Age Profile

Monmouth's housing stock is predominantly older, with a median build year of 1955 that reflects decades of construction before federal plumbing standards were tightened. The 1986 ban on lead solder and the pre-1970 era of lead service lines are both relevant benchmarks here - a significant share of the residential inventory predates one or both of those cutoffs, creating an elevated baseline for plumbing-related lead risk that aggregate water quality data may not fully reflect at the household level.

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

Monmouth: Remediation Cost in Perspective

Looking at how documented remediation costs fit within Monmouth's property market, the equity share lands in the elevated tier - a result that positions the household financial perspective as one requiring structured preparation, where mapping costs against household budget, documenting scope early, and sequencing by urgency are the practical tools that distinguish manageable outcomes from financially disruptive ones.

Median Home Value
$100,900
Est. Remediation
$2,700
Remediation as % of home value 2.7%

At 2.7% of home value, remediation costs in Monmouth represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,750–$3,900. Home values here are 45% below the Illinois average.

Protecting Children from Lead in Monmouth

86%
Homes Built Before 1986

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.

Before the federal solder ban, lead solder was a routine plumbing material, and 86% of the Monmouth inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.

A/V Share of Claim-Record ZIPs

Historical NFIP data for Monmouth contains 8 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $18,967. 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>$2,700</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.
