Housing & Infrastructure in Coupeville
With 47% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
When a home in Coupeville was built matters for lead because federal rules adopted in 1986 limited how much lead new plumbing could contain; the local median build year is 1982. A median sits in the middle of a range, so some homes are older and some newer, and past repairs may have changed the pipes in either group. A plumber can identify the materials inside a home, and a lab test measures what reaches the tap.
Most homes in Coupeville were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Coupeville Homeowners
How large is the remediation estimate next to home prices in Coupeville? Small in relative terms: it amounts to 1% of the median value or less, although the dollar figure below is still an estimate and actual costs vary by property and contractor.
Estimated remediation costs in Coupeville can be compared with local home values. The $600–$2,300 estimated range can be set against the median property value; actual costs vary by home. Home values are 24% above the Washington average.
Lead Exposure Risk for Children in Coupeville
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Historical NFIP Claim Context in Coupeville
Historical NFIP data for Coupeville contains 7 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $4,405. 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 $1,100 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.
